Joe Rogan Podcast, check it out!
The Joe Rogan Experience.
Train by day, Joe Rogan Podcast by night, all day.
neil degrasse tyson
I don't want every one of my sentences to sound like Barry White.
joe rogan
Is that what it sounds like in your ears?
neil degrasse tyson
In headphones, they do.
It's like, oh, hey, baby.
unidentified
I just can't.
neil degrasse tyson
Whereas without the headphones, I'm just regular.
unidentified
All right.
neil degrasse tyson
Ready?
Oh, ready.
joe rogan
Good to see you.
neil degrasse tyson
Hey.
joe rogan
What's happening?
neil degrasse tyson
Show.
joe rogan
I'm excited to talk to you.
I'm excited to talk to you about a bunch of things, but I've been paying attention to all the web telescope.
neil degrasse tyson
Oh my gosh.
joe rogan
Fascinating.
neil degrasse tyson
It's all that.
joe rogan
Could you please explain the difference in the ability of the capabilities of this telescope versus what we've had previously?
neil degrasse tyson
Yeah, so first of all, it's all that, and the excitement was in part because so much could have gone wrong with this thing, and the fact that nothing went wrong, we were ecstatic.
joe rogan
Could you explain how complicated it is to get something like that?
neil degrasse tyson
Yeah, so one of the great challenges that we face is, how do you put a telescope in orbit that's bigger than the rocket that's gonna launch it?
Is that even possible?
And the Hubble telescope, do you know what set the size of that?
94 inch diameter mirror.
That's the biggest mirror you could fit in the payload of the space shuttle.
That's what set the size of that telescope.
Big as it was, we would have made it bigger if the space shuttle were bigger.
Now, I don't know if you've seen the Hubble telescope.
There's a replica of it at the Air and Space Museum.
Let's take a photo of it.
It's there hanging from the ceiling, but if you want to know, it's about the size of a Greyhound bus.
So, the space shuttle deployed a Greyhound bus into orbit, which is the Hubble Space Telescope.
And the value of the Hubble was that you could update it with servicing missions, and it was serviced many times.
And as a result, it lived within our culture for three decades.
There are people who came of age only ever knowing the majesty of the universe as delivered to you by the Hubble Telescope.
30 years worth of this.
Think about it.
Most other telescopes, they put into orbit, and they have a five-year mission, and then they come down.
So they don't have a chance to get inside you, to become something that you...
Oh, you got a nice visual there.
So that's the Hubble telescope on the left, which every year, every year, I post a tweet.
At the end of the Stanley Cup, and I say, the Stanley Cup and the Hubble telescope had the same designer.
joe rogan
Really?
neil degrasse tyson
No, I'm just kidding!
No, just look at the thing!
It looks like the Stanley Cup.
joe rogan
A little bit.
neil degrasse tyson
A lot!
joe rogan
I wouldn't confuse the two if they were in a room together.
neil degrasse tyson
So here's the thing.
So notice the Hubble telescope, its diameter is the spherical shape that fits in the spherical payload of the space shuttle.
So now we want to put a bigger telescope into orbit.
How do you do that?
And so this is where you need engineers, clever engineers.
We say, here's a rocket, one of the most powerful rockets we can use, but the fairing, that's the place where you hold the payload, can only be so big.
And they say, all right, why don't we fold the telescope?
Now, how are you going to fold the mirror?
Oh, you...
Turn the mirror into segments, hexagons.
Hexagons, one of only three shapes that can tile a surface, a square, a triangle, and a hexagon.
No other shape can do this.
So, well, you can have other irregular shapes that can match up.
You can tessellate what it's called.
But if you have what's called a regular polygon, so here in the image there, what you can see is all of the mirror segments.
Those fold.
Into a narrow structure along with the unfurling solar panels as well as the heat shield.
Notice that it was made in Northrop Grumman.
By the way, Grumman has a long history in helping NASA put stuff in space.
The LEM, Lunar Excursion Module, remember that?
The thing that landed on the moon?
That was designed and built in Bethpage Long Island at Grumman Aerospace.
And you go to Bethpage today, people still stand tall because they had aunts and uncles who worked on that project.
Space is a force of nature unto itself in our sense of pride, in our sense of achievement.
And our sense of what operates on civilization to take us into the future lest we continue to regress and move back into the cave which we came.
There it is all folded up in the image we now see for those who are watching this.
And you slip that into a fairing and then you launch it a million miles from Earth.
Opposite the sun from Earth.
And it unfurls like petals of a flower.
joe rogan
Is there an animation of how that goes down?
neil degrasse tyson
Oh, yeah.
Yeah, slow-mo animation.
Sure, he can find it.
And it's the deployment, how it deployed as it was on its way to its location, which is one of the Lagrangian points in orbit.
For every two objects that orbit each other...
There are five Lagrangian points.
So here we are unfolding.
So there we have solar panels coming out the side.
And there's the communication antenna.
And it has a unique set of baffles that shield it from sunlight.
So that the mirror and the detector can be very, very cold.
Because it's specially tuned to observe infrared that comes to us from space.
And infrared, as you may know, we normally associate it with heat.
Well, how am I going to detect something that's very, very cold in space if my detector is hotter than what I'm trying to detect?
There's no way to see something that is warmer than the temperature of your detector.
So your detector has to be very cold.
Extremely cold.
So these are the baffles, and there are many, many layers.
So that when sunlight hits one layer, That layer absorbs it and re-radiates it in both directions, forward and back.
So there's less that goes to the next layer.
So then the next layer re-radiates it, and by the time it gets to the fourth layer, hardly anything goes towards the telescope.
And so it is insulated, and it drops to deep space, cold temperatures.
And it's literally where the sun don't shine right now.
joe rogan
So the solar panels are getting the solar energy from the bottom.
neil degrasse tyson
Yeah, because that's the direction the sun is, correct.
joe rogan
So it radiates off the bottom, and those are the things that protect it.
And we see how all those layers...
neil degrasse tyson
All the layers, yeah.
Amazing.
Yeah.
And it's specifically tuned for the infrared part of the spectrum.
You remember the spectrum.
So you have visible light, right?
ROYGBIV, if you want to remember it.
Red, orange, yellow, green, blue, indigo, violet.
Those are the...
Parts of the spectrum we can see.
But there's light outside of this.
There's like beyond the violet, there's ultraviolet.
That's how you get that.
And below the red is infrared.
Not visible to the human eye.
By the way, insects can see ultraviolet.
We can't.
That's why bug zappers work.
You put a UV light in a bug zapper, The bugs say, oh my gosh, I love ultraviolet.
And then they get zapped.
And we're old enough to remember before there were bug zappers, you'd had a picnic bulb for Twilight picnics.
And it's like a yellow bulb, kind of yellow amber bulb.
It was a bug bulb.
It was sold as bug bulbs.
It's not that they repelled bugs.
It's that the bugs couldn't even see it.
Because their whole vision is shifted towards the ultraviolet.
And it leaves out the deep red.
So that's evidence we're smarter than bugs.
That's one piece of evidence that we're smarter than bugs.
So just to bring that to a closure, the earliest forming galaxies in the universe radiated a lot of ultraviolet.
So you might say, well, let's get an ultraviolet telescope.
No, because 14 billion years later, the expansion of the universe has redshifted the ultraviolet into the infrared.
So if you want to see the birth of galaxies...
You've got to know what they look like in the here and the now.
And in the here and the now, it's in the infrared.
So this is a telescope specifically tuned to see galaxies born at the edge of the universe.
And infrared also allows you to see deep into gas clouds.
joe rogan
Now, when they're showing you an image like this...
neil degrasse tyson
So right here, this is the Pillars of Creation, which were so named at the time Hubble first attempted this.
We were gaga over the Hubble image of this.
And now, like the JWST, oh my gosh.
For those who are more prone to religion, some have called this the Hand of God.
Because if you look at the Pillars, you can kind of picture like a thumb and fingers.
So...
But regardless, this is nearby.
This is the telescope peering deep into gas clouds that otherwise would enshroud what's going on.
And you get to see stars being born, planets being born.
And so what's remarkable about JWST is that to be tuned for the edge of the universe and the birth of galaxies is the same properties you would want to see the birth of stars.
A star is born right in front of your nose that would otherwise be cloaked by gas.
And infrared penetrates those clouds and enables you to see it as though the cloud isn't even there.
And you already know this because if you're driving through fog, you put on your fog lights.
The fog lights are not blue.
They're like reddish, amber.
That improves your ability to see through the fog.
If we could see infrared, that's the kind of light you'd use, then you wouldn't even know the fog was there.
That's why self-driving cars will be amazing.
It won't matter if it's foggy.
They'll be able to see everything.
Just give them infrared sensors.
The fog is irrelevant.
They can drive 100 miles an hour in dense fog, and all the cars will see each other.
And they want to change lanes, they tell other cars, I'm going to change lanes.
They'll part for them, open up, and we won't get 40,000 deaths a year as we currently do from automobile accidents.
joe rogan
Now, how much bigger is this telescope?
neil degrasse tyson
So, you want to think about collecting area.
And I forgot the exact number.
Something like eight times around there.
More powerful in the sense of it can see things eight times dimmer.
There you go.
So, that's about two and a half squared.
That's about eight times the area.
joe rogan
And the technology, obviously, is improved as well.
So, like, the ability that...
neil degrasse tyson
Well, our detectors are better, and let me remind you that when the Hubble was designed, it was designed in like the 1980s, and it was scheduled to go up, and then we had the Challenger accident.
And that delayed the shuttle program.
So there's Hubble sitting there in mothballs with an old Microsoft chip.
And by the time it launched, it was already not as fast as it could have been.
And so the very first servicing mission swapped all that out and put in better methods and tools for measuring what it is we always needed it to do.
So one sad part about this Is that it's not serviceable.
We have no access to that point in space a million miles from the moon.
We haven't left low Earth orbit since 1972. We're not going out a million miles from Earth to fix a telescope.
So that's unfortunate.
Maybe a robotic fix?
I don't know.
To refill some of the fuel.
It needs fuel to station keep.
joe rogan
Didn't it get hit by a micrometeor?
neil degrasse tyson
Yeah, well, that's the brakes when you're in space.
joe rogan
Yeah.
neil degrasse tyson
Yeah, but it doesn't affect the overall performance.
joe rogan
That's amazing.
neil degrasse tyson
Yeah, yeah.
Well, it's huge, and micrometeors will do small damage, but...
You don't want it in the middle of a meteor storm.
That would be totally bad.
joe rogan
And do they, I mean, they obviously know, like, where some of the asteroid belts are and where some of the, like, nearby Earth objects are.
neil degrasse tyson
Yeah, so in this context, so first, most asteroids are in the asteroid belt.
So that's between Mars and Jupiter.
So I have an asteroid named after me.
joe rogan
Congratulations.
neil degrasse tyson
I don't mean to brag or anything.
joe rogan
Can't you get a star named after you online?
neil degrasse tyson
Not authentically.
joe rogan
You just get robbed.
You just pretend it's yours.
neil degrasse tyson
They'll send you a map with your name drawn in the map.
joe rogan
So you pay for a piece of paper.
neil degrasse tyson
Yeah, they claim that it gets registered with the astrophysicists, but it doesn't.
There's only one way we name stars, and that's by committee and by traditions and this sort of thing.
They're fascinating traditions.
So planets are named after Roman gods.
And planet moons are named after Greek characters in the life of the Greek god Who's the counterpart to that Roman god.
So, Jupiter, for example, one of its moons is Ganymede.
Ganymede was the manservant of Zeus, and Zeus and Jupiter were corresponding gods in Greek and Roman.
And not only that, what's the number?
Is it about half, somewhere around there, of all the stars in the night sky that have names, have Arabic names.
So in my field, we have deep respect for people who made great inroads into understanding the natural universe.
And the golden age of Islam from a thousand years ago made material contributions in this regard.
And of course, Greek and Roman legends and this sort of thing.
So there they are in its influence on Western culture.
So, yeah, no, the universe is a fun place.
joe rogan
Pretty fun place.
neil degrasse tyson
Oh, yeah.
joe rogan
So, this James Webb telescope, in terms of its ability to recognize things, like what magnitude of improvement are we talking about from the Hubble?
neil degrasse tyson
Yeah, a factor of 10. Yeah, a factor of 10. Yeah, easily.
That's right.
Well, a factor of 10 for the things Hubble could see, but it's incalculable.
When it sees things that Hubble could have never seen, because Hubble was not tuned for the infrared.
So then you can't even compare it.
It's a complete other window opened up to the universe for you.
joe rogan
So what has changed in terms of our understanding?
The web has been in the million-mile orbit, or however far away it is, for how long now?
neil degrasse tyson
Well, it got there, and then we did some engineering.
So I guess a year, year and a half?
joe rogan
And what has changed in our understanding?
neil degrasse tyson
So, that's been people's first question, and what I want to do is temper that to say something a little different.
So, yes, we expect James Webb to make great discoveries.
We expect that.
But the first order of business is hardly ever, let's discover something new today.
It's, here's something that we have limited understanding of, let's improve on that.
And in so doing, we deepen our understanding of how things work in the universe.
That doesn't always involve overturning a previous idea or discovering something that nobody ordered.
All right?
That will happen.
We fully expect that to happen.
But we targeted parts of the sky initially because we know other telescopes have gone there before.
And we're going to say, how can we further advance and deepen our understanding?
One thing it's going to be able to do, and it has already done, You know how many exoplanets there are?
I don't know how many of your audience was born after 1995. How many 27-year-olds and younger?
joe rogan
Probably quite a few.
neil degrasse tyson
Quite a few.
Okay.
So I will take this opportunity to knight them Generation Exoplanet.
1995 was the first exoplanet discovered, a planet orbiting another star.
And I'll never forget that because it was my first time on national television.
I was freshly minted as director of the Hayden Planetarium in New York City.
And NBC sent a...
New York City is the media news headquarters, right, of all the networks.
So NBC sent an action cam.
They interviewed me because of my title, not because they knew or gave a...
Crap who I was.
My title was Director of the Planetarium.
And so I gave my best professorial reply.
I said, well, it's the Doppler shift.
This is how it's discovered and what we do and how we measure it.
And I was describing the fact that when you discover these planets, you don't actually see the planet.
You see the effect of the planet's gravity on the host star.
And so if you'd watch the host star, the host star like jiggles.
Okay?
Just a little bit in response to the planet going back and forth around it.
So you're measuring the star.
So I motioned that, like, with my hips.
And that evening, on the evening news, That's all they showed, was me jiggling my hips.
I said, oh my gosh.
Okay, that's how you're gonna do this.
Okay.
You don't want me to be Professor Neil.
You want me to be Soundbite Neil.
All right, so from then on, I practiced my soundbites.
And a soundbite's like three sentences.
joe rogan
Oh, so you recognize that this is the format now?
neil degrasse tyson
Correct!
And I said, I can't just give them my stump speech as professor of astrophysics.
It has to work in their medium.
And so I went home and stood in front of the mirror.
And had people just shout out things to me, anything in the universe, any idea, object, person, place, or thing.
And I would come up with like three sentences that are interesting, make you smile, and be tasty enough to want to tell someone else the anatomy of a soundbite.
So try it.
Say anything in the whole universe.
joe rogan
How do we know how...
neil degrasse tyson
No, just one word.
Just say anything.
joe rogan
The Big Bang.
neil degrasse tyson
Big Bang.
Ooh, the birth of space-time energy and everything we know and love about this universe.
It occurred 14 billion years ago, and we have no idea what happened before it.
And we're still expanding, as we will forever.
I read an article- That's my sound bite for the Big Bang.
joe rogan
It's a good sound bite.
I read an article about the Webb telescope and what they were taking into consideration is the possibility that the Big Bang may be incorrect and that the universe might be larger and older than we think.
neil degrasse tyson
So, I hesitate to ask what pages on the internet you hang out on.
joe rogan
It wasn't saying the universe is older.
It's saying as more data and new information comes in, there is a distinct possibility that the Big Bang might just explain the reach of the technology and not the actual scale of the universe itself.
neil degrasse tyson
Okay, so the way to think about this is...
And this is the way science has worked since basically the year 1600 where Galileo sort of starts codifying what people knew probably should be happening but no one really did it in large scale.
If you have an idea about something, then you test it multiple ways and get other people to test it.
And if the tests give you consistent results, you have a new understanding of the universe.
When that happens, That knowledge of the universe doesn't go away.
It doesn't get undone.
What happens, typically, is you have a deeper understanding of the universe in which that understanding gets embedded.
And you realize that you only understood a small part of a larger whole.
But the small parts you did understand, where you had multiple experiments that confirmed it, that doesn't change.
So the cleanest example of this, and I'll get back to your question, is Newton's laws of motion and gravity.
You know, did anyone see anything move faster than a galloping horse in his day?
Probably not.
And so...
The Newton's laws of motion and gravity worked.
They worked not only for galloping horses, it worked for the moon in orbit around the Earth.
And the Earth in orbit around the Sun.
And Jupiter's moons in orbit around Jupiter.
Alright?
And for the planets.
unidentified
So...
neil degrasse tyson
Okay.
But wait a minute.
It doesn't work for Mercury.
Mercury's orbit is not following Newton's laws.
Is there something wrong with the data?
Let's check it.
Data's correct.
Oh my gosh, what's happening?
Einstein comes along and says, I have a new understanding of gravity and a new understanding of motion.
And it accounts for this weirdness in Mercury's orbit.
joe rogan
What was the weirdness?
neil degrasse tyson
Its shape was not exactly what Newton's laws of gravity would give you.
Its shape could only be accounted for when you throw in Einstein's theory of general relativity.
Why?
Because the Sun's gravity is so monstrous and Mercury's orbiting close enough to it that it's being influenced by extra phenomenon going on in the universe that's the product of very high and significant gravity.
And so, so then do we throw Newton out the window?
No, actually.
You know what Newton's laws are?
They're what Einstein's laws look like when you put in low speeds and low gravity.
If you put in low speeds, they become Newton's laws in that limit.
Newton's laws don't stop working where they used to work.
Apollo, to the moon, used only Newton's laws.
Because Einstein didn't matter at those scales.
The moon and earth and rockets, we're not going fast enough for any of that to matter.
But when you start going fast enough, you cannot use Newton's laws.
You have to use a deeper understanding.
Now, where does Einstein take us?
You go into the center of a black hole, you get black holes from Einstein.
Center of a black hole is a singularity.
All the theories say the matter occupies zero volume.
Thereby having infinite density.
And that's kind of weird.
What?
No, you can't have infinite.
No.
That's a limit of Einstein's theory.
That's where it breaks down.
Some have joked that's where God divides by zero.
Remember in math class, you can't divide by zero.
It's not defined or not allowed.
So in Einstein's equations, we're dividing by zero at the singularity.
So we all know That as brilliant as Einstein was, and as successful as his general theory of relativity has been, it has limits.
And one limit is the center of a black hole, and another limit is the very birth of the universe itself.
Getting back to your question, the Big Bang.
So we have top people working on trying to resolve this singularity problem.
And in so doing, you get to some ideas that, well, maybe our Big Bang, because the Big Bang is not going to go away.
All the data support this.
So now I've got this Big Bang thing, okay?
And, well, is this embedded in something bigger?
So when you put like quantum physics and general relativity and you try to come up with some bigger understanding, deeper understanding, strength theorists have been all into this, you get a multiverse.
We didn't pull that out of our ass.
That came out of the equations.
So how old is the multiverse?
I don't know.
It's definitely older than our universe because it birthed our universe and it births other universes and it births The way the equations drive it, an infinity of universes.
This is the idea that maybe there's a version of us in another where I'm bald and you got the afro, but everything else is the same.
joe rogan
And also a version where everything's the same.
neil degrasse tyson
Where everything would be the same, yes.
joe rogan
Everything you've ever said has been said before exactly in the same order.
neil degrasse tyson
Correct.
There's no reason to presume that everything in this universe isn't or hasn't already played out.
In the exact way in another one of these infinite universes.
joe rogan
And in an infinite number of different ways.
neil degrasse tyson
Correct.
And so that is what comes out of the equations.
So that makes the Big Bang a kind of a small part of a much larger whole.
And so, yeah, we're ready for that.
But the fact that the universe had a beginning 14 billion years ago, and there's the cosmic microwave background, all of these features...
Are intact.
They're not going to all of a sudden not apply.
That's my point.
That's my long answer to your very clean question.
joe rogan
So this thing that happened 14 billion years ago, what is the predominant theory of why?
neil degrasse tyson
So this multiverse concept gives us a reason why.
Okay?
It's like, imagine you're rolling around in a basin, okay?
And you're stable there.
You're just fine.
But then something kicks you out of the basin, and you didn't know that there's a huge hill to roll down after you come out of that basin.
But you didn't know that.
You thought everything was just fine.
You roll down that hill, you're gaining energy.
At the bottom of the hill, something stops you.
And then where does all that energy go?
One of the hypotheses, and I'm highly simplifying here, is that the energy gained by rolling down a hill And these are energy hills that would exist in this sort of higher dimensional space that we're talking about.
That energy has to manifest in that object somehow, and it becomes an explosion.
With enough energy, it gives birth to matter, everything that we know and love, and it expands.
Because when you concentrate that much energy in a small spot, that's the only thing you can do.
joe rogan
I understand that you're simplifying it, but I don't understand.
neil degrasse tyson
Simplify it in the sense that by using this basin analogy and rolling down a hill, that there are equations of the energetics of a system, and this is called a false vacuum.
So you can be in a place that's not the true bottom energy state of the system, but you think everything is fine, but it's not.
If you move around among these hills and valleys, you end up birthing universes out the other side.
And this multiverse concept actually delivers this for you, basically for free.
joe rogan
That thought would be that the Big Bang is just one of many events that happen in the multiverse.
neil degrasse tyson
Correct.
And not only that, it could be that other Big Bang events It might have a slightly different laws of physics in it.
So you want to watch out for that.
If you cross over from one universe to the other and the charge on the electron is slightly different, all your atoms could just scatter or compress into a pile of goo.
Yeah, so take something to test first.
joe rogan
Yeah, send a chicken out there.
unidentified
Send a chicken out there.
neil degrasse tyson
Chickens get no respect.
What happened to guinea pigs?
joe rogan
Well, guinea pigs are cute.
neil degrasse tyson
They're cute and furry.
Oh, my gosh.
joe rogan
Chickens are way easier to just send to space.
neil degrasse tyson
I spent a whole section in this book talking about people who love animals and want to care for them and don't want to eat them, but the only loved ones that are cuddly.
joe rogan
Oh, yeah, for sure.
neil degrasse tyson
You'd make a plush toy out of it.
joe rogan
My agent said that.
She knows I hunt.
She's like, you should hunt pigs because they're ugly.
I'm like, how dare you?
First of all, domesticated pigs are adorable.
neil degrasse tyson
They are, in fact.
joe rogan
Yeah, domesticated dogs are ugly, too, because they're desperate.
neil degrasse tyson
In fact, I have a...
I have a voice cameo of a pig in a Disney XD cartoon called Gravity Falls.
It's a farmhouse and there's a pig that lives with everybody.
And the pig eats some slop that the kids are told makes you smarter.
And so they bought it at a fair or something.
So they went to sleep putting the slop on their forehead.
Thinking it would get into their head and make them smart.
But the pig sees it on their forehead and licks it off of their forehead.
And then overnight, the pig becomes a supreme genius.
Builds an atom smasher.
Builds a voice translator.
And while the pig is smart, I'm its voice.
It's cute.
It's cute.
And so, but what was I talking about before?
joe rogan
Big Bang, multiverses, different laws of physics.
neil degrasse tyson
Yeah, slightly different laws of physics are a fascinating prospect.
How they might vary and how you might want to avoid it.
Oh, but I was talking about you want to save animals.
I've never seen anyone say, save the leeches.
joe rogan
No, no one cares about bugs.
neil degrasse tyson
Save the ticks.
In particular, parasites.
Save the mosquitoes.
Mosquitoes, you know, the biggest enemy of humans, as big an enemy as we are to each other through warfare and the history of civilization, the greatest enemy to human life has been the mosquito.
Responsible for more than a billion human deaths in the history of civilization.
And so, here we have mosquitoes, ticks, tapeworms, you know, go down the list and you can ask, if you're really into animals and don't want to kill them, if you heard that ticks were endangered, Would you start a movement to protect ticks?
Would you do that?
And if you would, more power to you.
But I'm thinking you're not.
joe rogan
Why would you if you know about Lyme disease?
neil degrasse tyson
This is my point.
This is my point.
By the way, the Lyme virus wants to live too, right?
These are all creatures on God's green earth, right?
And so you end up being a species bigot.
In the chapter, Meatarians and Vegetarians, there's the philosophies that each of those camps will embrace.
And the question is how...
Thoroughly thought through are those philosophies.
In one example, let's say you don't want to kill animals.
So you have a humane mousetrap in your basement.
Okay?
Why not?
You don't want to snap the neck of the mouse.
That's cruel.
And you like animals, right?
So you save the mouse.
You got to check on it every few days because they dry out quickly if you trap it.
So what do you do when you catch it?
What do they do?
joe rogan
Release it.
neil degrasse tyson
Release it back into the wild.
Guaranteeing the mouse gets eaten whole by an owl or pecked apart by all manner of woodland predators between 9 and 18 months of its life.
So the safest thing to do with your mouse is to leave it in your basement.
If you really care about animal life and the mouse managed to get into your basement, leave it there.
It'll live up to six years in your basement.
joe rogan
I lived in Colorado for a while next to an ashram and I was visiting the ashram and talking to the woman who runs it and she sprayed raid all over these ants.
And I go, what are you doing?
And she's like, well, it's unfortunate, but we have to address the fact that we have an infestation of insects.
I'm like, you just mass killed all these living beings with poison from the sky!
And you did it in front of me.
neil degrasse tyson
Aerial assault.
joe rogan
While you're espousing the benefits of Buddhism and meditation.
neil degrasse tyson
Yeah, so people kind of cherry pick.
joe rogan
Yeah.
neil degrasse tyson
And I understand it, but I don't mind if someone cherry picks as long as they're completely self-aware of it.
joe rogan
Most people aren't.
neil degrasse tyson
And by the way, the home where you're saving the mouse...
I did a rough calculation.
It's probably made from the wood of about 50 trees.
Each tree could have lived 100 years but didn't because it was cut down to make your home.
The studs, the 2x4s, the floorboards, the wall panels, the siding.
And each of those trees was home to birds and insects and fungus and squirrels and And every day of that tree's life, via photosynthesis, it created 15 times the mass of the mouse in breathable oxygen.
So I ask you, who do you think nature cares more about?
The tree or your one-ounce mouse?
joe rogan
Probably the tree.
neil degrasse tyson
I'm thinking.
And some trees live a thousand years.
joe rogan
Well, have you paid attention to some of the new research that's being done about how trees communicate with each other?
neil degrasse tyson
I'll get to that.
Yeah, I'll get to that.
That's in that chapter, the vegetarians and vegetarians chapter.
So trees are fascinating.
I've heard people say, well, the mouse has a beating heart, and the tree does not, or plants do not, and animals do.
And I said to my, well, let me think this through.
If you cloak a tree, does it not suffocate?
If you cut a tree, does it not bleed?
If you cut off its nutrients at the base, does it not wither and die?
joe rogan
Well, when they're aware they're being eaten, they release plant defense chemicals.
unidentified
I'm getting there.
neil degrasse tyson
I'm getting there.
All I'm saying is the tree gets nutrients from the soil to the topmost leaf.
It does it not for want of a beating heart.
It does it in spite of not having one.
It has a circulation.
joe rogan
It just has a different way of life.
neil degrasse tyson
It's where I get my maple syrup from.
Tree blood.
So to fault a tree or plant life for not having a beating heart, when it's not that they need one and don't have one, it's that they don't need one and never wanted one.
Now, you're talking about the mycelium.
So this is a interconnected network.
It's a fungal network underfoot in a forest where it connects multiple kingdoms of life.
There are four kingdoms.
You might have learned that there were two.
We've upped it since then.
Those two kingdoms are still intact, but like I said...
Now, there's more.
It's embedded in a larger truth.
There's the plant kingdom, animal kingdom, fungal kingdom, and then we have a kingdom that includes all of the bacteria and archaea and other microscopic life forms.
And so, here's an interesting fact.
I lost sleep for a week over this.
Ready?
If you look at the common ancestor between fungus and animals, Because the tree of life ultimately has one taproot.
And as it splits, it speciates, and you get all these things.
The diversity of life on Earth is enabled by the fact that life can speciate.
You look at the common ancestor between animals and fungus.
The common ancestor between humans and mushrooms split later.
Than its common ancestors split with green plants.
What that means is we and mushrooms are more alike than either we or mushrooms are to green plants.
joe rogan
Well, mushrooms breathe oxygen.
neil degrasse tyson
All I'm saying is you grill a portobello mushroom?
What's the first word people use to describe it?
joe rogan
Vegetarian.
neil degrasse tyson
No, we talk about mushrooms tasting meaty.
joe rogan
Yeah.
neil degrasse tyson
Yeah, meaty.
Meaty mushroom.
Last I checked, no one has ever accused kale of tasting meaty.
joe rogan
No.
neil degrasse tyson
So, in a way, we're kind of biting into ourselves.
Plus, mushrooms, you know, shrooms, you know, people have whole relationships with mushrooms.
joe rogan
Oh, yeah.
neil degrasse tyson
Yeah.
Oh, yeah.
And mushrooms are fungus.
Fungus thrives on our body.
joe rogan
Have you ever done psychedelic mushrooms?
neil degrasse tyson
I've never done anything psychedelic.
joe rogan
Why?
neil degrasse tyson
Can I tell you why?
joe rogan
Yeah, please do.
neil degrasse tyson
So, I don't know if it's a good reason...
I don't know if it's the best reason that can exist, but for me it's a really good reason.
The human mind barely works as it is.
Barely.
You ever see a book of optical illusions?
No one doesn't love a good book of optical illusions.
And you turn the page, oh, what is that?
Oh, is it in the page?
Out of the page?
Is the line longer?
Is it shorter?
And you scratch in your head.
These are simple line drawings that confound the human mind's ability to interpret.
Our brain barely works as an accurate decoder of the natural world around you.
You now want to stir in chemicals?
I recognize it'll take you on a ride, but I have always valued objective reality.
I don't want anything interfering with my understanding of what is actually happening in front of me.
And there are people who would claim that under the influence, they're accessing some actual other reality.
All I can say is, if in that other reality you can, you know, invent the James Webb Space Telescope, tell me about it.
If you can figure out how to fly, you know, and if you can do that, tell us about it.
And there are people who say, oh, I visited Venus when I was on a head trip.
Did you bring back evidence?
Evidence matters?
unidentified
Okay.
neil degrasse tyson
Did you bring it?
No.
But it was in their head.
joe rogan
Well, the material world, what we're talking about is actual physical objects, right?
It's like if you could bring back something.
neil degrasse tyson
The physical universe.
The physical world.
joe rogan
The physical – what they're experiencing is something akin to – you could call it a hallucination.
You could call it a portal where physical reality doesn't exist and you only exist as consciousness.
neil degrasse tyson
Here's my skepticism.
I don't mind people saying that they visited another planet.
Or whatever, wherever they're visiting, or some astral plane, okay?
I don't, okay.
I'm, you know, write a travelogue and share it with people, as some have done.
I guess I would ask whether what you experienced is part of an objective reality that we can all recognize.
Because if it's not, then it's completely in your head.
And if it's completely in your head, it's less useful.
joe rogan
But what do you mean by that?
Part of an objective reality?
neil degrasse tyson
An objective reality.
So here's an example.
When people have these near-death experiences, okay?
Or one where they're dying on a table and they are commonly described.
They leave their body and they look back on themselves, okay?
That's a thing going...
That's something, okay?
Let's investigate this.
Okay?
So, the test for whether you really left your body or whether you were hallucinating it is get some writing that faces the ceiling up above your body.
Okay?
They've done this experiment.
And if you're floating above your body, above that piece of paper, when you come back to life, you should be able to say what's written on that piece of paper.
That is yet to happen.
joe rogan
If you get above it.
neil degrasse tyson
Yeah, if you get above it.
Correct.
That is yet to happen.
That'd be really good...
joe rogan
So where would that piece of paper be suspended?
neil degrasse tyson
No, you have to put it up on a shelf or something.
Yeah, you'd be able to put it in a way that it would be clearly...
joe rogan
But then the person would have to die knowing that piece of paper was there and then be brought back?
neil degrasse tyson
Possibly.
If...
joe rogan
So you'd have to tell them, hey, I know you're going to die.
neil degrasse tyson
You're going to die.
If you come back, I have a piece of paper up here.
Go read from it.
joe rogan
That seems like a pretty ridiculous experiment to try to achieve.
neil degrasse tyson
Wait, wait, wait, pause.
Pause?
Ridiculous experiment.
joe rogan
So like, hey, I know this guy's about to die, but instead of concentrating on bringing him back to life, let's write down on a piece of paper and leave it on the show.
But who the fuck is going to do that?
neil degrasse tyson
You know what they did?
joe rogan
What?
neil degrasse tyson
In 1895, after Wilhelm Röntgen discovers x-rays, and they find out it penetrates your body, and you can see bones inside your body, you know what they did?
unidentified
What?
neil degrasse tyson
They set up x-ray machines at the bedside of dying people to see if they can see a soul leave the body.
joe rogan
Hmm.
And everybody just got cancer from radiation.
neil degrasse tyson
They died from cancer?
I thought that was an admirable attempt.
joe rogan
Yes.
neil degrasse tyson
Interesting.
To make a measurement.
joe rogan
Yeah, that's interesting.
neil degrasse tyson
Yes.
joe rogan
But how would you possibly know that someone is going to die and or have a near-death experiment?
A near-death experience, rather, and then put a piece of paper on a shelf.
neil degrasse tyson
What you want to do, you'd have to be really organized about that.
unidentified
Yeah.
neil degrasse tyson
And if you want to do this en masse...
joe rogan
You'd have to just, like, have shelves in every bedroom.
neil degrasse tyson
Have shelves in every room.
Of every ER. Every ER, correct.
Or, yeah.
joe rogan
How often does that happen where people have above their body experiences where they leave their body?
neil degrasse tyson
It's very frequently reported.
joe rogan
Very frequently?
neil degrasse tyson
Oh, yeah.
I'm just saying that the brain is capable of so much extraordinary thought within itself.
joe rogan
Of course.
neil degrasse tyson
That what I care about for the...
World is what is objectively true, and what's objectively true can be verified by multiple people.
And if it's only true within your head, it's not useful, is all I'm saying.
joe rogan
How could it not be useful if it's useful to you?
But hold on, if it's useful to you, and then that usefulness to you actually manifests itself in something that gets created because of this experience, like Kerry Mullis created the PCR method because he had an acid trip, and during the acid trip came up with this idea.
neil degrasse tyson
So, what we'd have to ask is, how frequent So you get everybody who takes trips of any kind, be it mushrooms or acid, and look at the body of their new thoughts that have come from them, For them having, when they credited, okay?
And Carl Sagan was a big pothead, okay?
And highly productive scientist.
So the question is, does it give you some insight, which when you were not under the influence, gets you closer to an objective reality?
That's an interesting question.
joe rogan
Carl Sagan actually believed that there was What was his description, the way he described it?
But he said he believed that there are thoughts that were only available when you were under the influence of marijuana.
neil degrasse tyson
That is certainly the case for any drug, right?
joe rogan
Yeah, but he felt like those thoughts were beneficial.
neil degrasse tyson
Well, I can ask, are those thoughts more connected to reality than if you were not so influenced?
I did an experiment with myself, okay?
When I first started writing in graduate school at a monthly column, You know, there's that stereotype of Hemingway with a drink, you know, and they're writing, and that's their creative moment.
I said, I don't really like hard liquor, but I like wine, so I said, let me get a bottle of wine and drink wine while I write.
And I said, yeah, this is good, this is good, and I'm doing it.
And then...
I did it without wine.
This is an experiment I conducted on myself.
And it was not as fun composing without the influence of just some, you know, a smooth, sort of low-level sort of wine buzz.
But I looked at the two There was no contest.
My completely sober writing was vastly better than what I was writing under the influence of several glasses of wine.
Even though I believed it was really good.
joe rogan
But hold on a second.
What kind of writing are you talking about?
If you're talking about fiction?
neil degrasse tyson
No, no.
Prose.
joe rogan
Okay.
neil degrasse tyson
Prose.
joe rogan
One of the greatest examples of fiction being enhanced under the influence of drugs and chemicals is Stephen King.
If you go and read Stephen King's early work versus the stuff after he got sober, and I'm a gigantic Stephen King fan.
neil degrasse tyson
Was it just alcohol in his case or were there other drugs?
joe rogan
A lot of cocaine, a lot of alcohol, cigarettes, a lot of cigarettes.
It was way better.
It's vastly superior.
Darker, deeper, stranger, more bizarre, more shocking.
neil degrasse tyson
In the day, you're saying.
joe rogan
In the day.
Read it today.
Read Carrie today.
unidentified
No, no, no.
neil degrasse tyson
I meant you're saying what he created in the day under that influence.
Yes.
joe rogan
The stuff under the influence.
The stuff he created under the influence.
neil degrasse tyson
Carrie is deeply dark.
joe rogan
It's so dark.
neil degrasse tyson
Oh my gosh.
joe rogan
It's so dark.
neil degrasse tyson
So when was Shawshank?
joe rogan
Pet Sematary.
Almost all of them.
neil degrasse tyson
When was Shawshank Redemption?
joe rogan
I think all of them were when he was fucked up.
He wrote some good stuff after he was fucked up, but like Cujo, he doesn't even remember writing it.
neil degrasse tyson
And it's fantastic.
So is this something you would recommend?
For creative people.
joe rogan
I recommend Stephen King.
Get back on Coke, sir.
Stay off Twitter.
Get back on Coke.
I'm kidding.
neil degrasse tyson
So my one little experiment with glasses of wine...
joe rogan
Yeah, that's not enough.
That experiment's not enough.
I personally feel that under the influence of marijuana, I come up with some of my best ideas for comedy, for stand-up comedy writing.
I like to...
I do the George Carlin method.
neil degrasse tyson
I hear you got a new show ready to drop.
I'm looking forward to that.
I love your work, by the way.
joe rogan
Thank you very much.
Thank you.
I do the George Carlin method.
I write sober, and then I punch it up high.
neil degrasse tyson
Okay.
joe rogan
As opposed to the opposite.
neil degrasse tyson
Yeah, interesting.
joe rogan
Well, George Carlin had a great point.
He's like, you should write about things that you're thinking about and things that are, like, important or things that are on your mind, and then he would, like, let it sit, and then he would smoke pot and go back to it.
And then he would come up with all the funny.
neil degrasse tyson
Interesting.
joe rogan
All the ridiculous aspects of it, and he would interject them into there.
neil degrasse tyson
Uh-huh, uh-huh.
joe rogan
Yeah.
neil degrasse tyson
Yeah, so I'm just saying, to the extent...
I'd like to know how reliable that is.
joe rogan
Well, here's the other point that I should say.
There's many people that don't do any drugs that write fantastic stuff.
And there's many comedians that are completely clean and sober that have done their best work once they got clean and sober.
That's true, too.
Both those things are true.
But I think they're tools.
neil degrasse tyson
And we lost some comedians.
I mean, you know, Mitch Hedberg, for example.
joe rogan
Yeah, so Mitch was genius.
neil degrasse tyson
Yeah, I really loved his stuff.
joe rogan
And he had a really bad drug.
His injectable heroin was his thing, which is one of the worst.
But the point is, it's like...
They're tools.
And I used to have a joke about it, like that marijuana is like any other tool.
It's like a hammer.
You could build a house with a hammer, or you could hit yourself in the dick if you're fucking crazy.
And that's the problem with all sorts of things.
They need to be managed responsibly, and people need to understand what the effects are, what the dosage is, and that's where science comes in.
neil degrasse tyson
Here's what I'll do.
Here's what I'll do.
I still have some writing projects that I'm going to finish.
joe rogan
Do I take mushrooms?
neil degrasse tyson
No.
When I'm done with what I know I wanted to write before I died, then I will consider this.
joe rogan
Then come to daddy.
neil degrasse tyson
I'll come to papa.
I'll come to papa.
joe rogan
We'll hook you up.
neil degrasse tyson
And then I'll see if some new creative thing comes out of me at that time.
joe rogan
Well, I don't know if new creative things will come out of you, but I think thoughts will come out that probably wouldn't exist without them.
And when you're talking about like really breakthrough psychedelic moments like DMT or mushroom psilocybin, one of the really fascinating things is they mimic neurochemistry.
Like, DMT is in the brain, and it's in all the organs, and it's a part of natural human neurochemistry.
neil degrasse tyson
Well, except, of course, so is fentanyl.
joe rogan
Fentanyl is a part of the human neurochemistry?
neil degrasse tyson
No, you have receptors for it.
joe rogan
Right, but DMT is produced by the human body.
I mean, how many of these Would
neil degrasse tyson
I have to see to be convinced that it's a reliable consequence of it?
joe rogan
I think you would have to do it.
This conversation is like talking to a person who's lived in an underground tunnel their whole life who's dismissing sunlight.
They're like, what's the big deal with sunlight?
I'm fine down here with light bulbs and you and your sunlight.
unidentified
Oh yeah, photosynthesis.
joe rogan
I've got hydroponics.
neil degrasse tyson
So you're being a...
A very effective drug pusher.
joe rogan
But the drugs that I'm interested in are not dangerous.
They're not ones that kill you.
Like, I've never done cocaine.
I've never done heroin.
I've never done amphetamines.
I'm not interested in those.
neil degrasse tyson
Does cocaine kill you?
joe rogan
It can.
neil degrasse tyson
It can if you're rich enough.
joe rogan
Well, it certainly can kill you today because so much of it is laced with fentanyl, which is one of the number one killers of young people, unfortunately, is fentanyl contamination of drugs.
But I'm interested in pharmacology.
I'm interested in what happens to the mind when it's under the influence of different substances.
neil degrasse tyson
Yeah, I guess I'm less interested because I have to think more about what you said.
Look at how people misinterpret reality when they're not on anything.
joe rogan
It's a good point, and another good point is there's many people that under the influence of those drugs.
neil degrasse tyson
The failure of eyewitness testimony just to say what actually happened.
joe rogan
Sure, and that's under extreme duress.
neil degrasse tyson
That's terrifying.
People end up in jail because of that.
joe rogan
Yes, for the rest of their lives.
Yes.
Listen, I've had many, many conversations with people on this podcast about that because I've worked with my friend Josh Dubin who was originally an ambassador for the Innocence Project and has done a bunch of stuff on his own where he's gotten many, many, many people out of jail.
neil degrasse tyson
The fact that an Innocence Project even has to exist in this world is itself a travesty.
joe rogan
Well, I'm hoping that with science there's going to come a time where we can actually read the contents of people's minds.
And that this will no longer be, I remember this.
neil degrasse tyson
It's an episode of Black Mirror.
joe rogan
Yes.
neil degrasse tyson
Yes.
But I think maybe, yes, that would be interesting.
joe rogan
But isn't the problem is that false memories are a real thing.
neil degrasse tyson
So there are people who believe something, and if you read their mind, you'll just see what it is that they believe.
joe rogan
But I wonder if you could sort of back-engineer that belief.
I wonder if it could get to the point where you could say, oh, you believe this because this is a memory of the way you've described the memory.
neil degrasse tyson
No, we just do it Black Mirror style and you have a chip that records everything that you see.
joe rogan
That's probably the future.
neil degrasse tyson
There's a chapter here called Law and Order, where I get into the role of science in deciding whether someone is guilty or innocent.
And it's the idea that in a courtroom, someone says, I need a witness.
This is like...
In the court of science, that's the last thing you are ever asking for.
joe rogan
Yeah.
neil degrasse tyson
Because we know, psychologists knew this first.
The rest of us, you know, figured it out after the fact that I would just testimony is one of the least reliable forms.
The third time I was rejected from jury duty, I show up dutifully, okay?
And they...
The third time, they said there was a woman who was robbed on the street of her groceries and her purse.
And they had the person who she accuses, positively identifies, and her.
And it's a literal he said, she said, okay?
We read the particulars of the case.
She said he robbed her, the groceries took it, and then ran off.
When the cops found the guy, he was not in possession of anything she said he took.
They looked in the area, if anything stashed in dumpsters or anything, they didn't find anything.
Okay, so that's the state of the case.
And the judge reads the particulars and goes to the, I'm down to the last 15, I'm almost on a jury!
For the first time I'm out, I'm almost there!
And said, do you have any...
Does anyone think they would not be able to convict based on the kind of information and evidence that's been presented?
And they said, juror 14, whatever you're numbered, right, until you're selected.
I said, yes, I'd have a problem.
If the only evidence available is eyewitness testimony, then everything I know about it Tells me I should not trust it on the level where you end up putting someone in jail.
So I could not convict if that's the only evidence you have.
What the judge said next was, are there any other jurors, like juror 14, who needs more than one witness before they would be able to convict?
And I said, should I jump in now and say, that's not what I said.
What should I do?
The person in front of me said, Your Honor, that's not what he said.
Ah!
Okay?
And I said, oh, thank you.
Thank you, Jesus.
He said, that's not what he said.
And I resisted with all my might to say, Your Honor, you were eyewitness to what I said 20 seconds ago and got it wrong.
Yes!
But I resisted, but I was nonetheless on the street 20 minutes later.
joe rogan
I think you should have said that just for his own edification.
neil degrasse tyson
No, it was a she, by the way.
joe rogan
Sorry, I'm sexist.
neil degrasse tyson
You're totally sexist.
What's wrong with me?
We've all known that forever.
joe rogan
Slap myself on the wrist.
neil degrasse tyson
So, I'm just saying, it's clear that the legal system...
Precision of...
joe rogan
Deeply flawed.
neil degrasse tyson
It's deeply flawed.
And they say, well, it's the best we have.
Well, then fix it.
I mean, if that's how you were talking, when they used to dunk people, and if you died face up, you were innocent and died face down, you were guilty.
That was the best they had then, but we improved on it.
joe rogan
Right.
If they drowned you, you weren't a witch.
Congratulations, you weren't guilty.
neil degrasse tyson
Well, it depends.
Yeah, that's right.
How you died, and you'd otherwise go to heaven.
Right.
So, plus there's...
In Columbus's voyage, there's a lot.
We talked about Columbus last time on the show.
joe rogan
Oh, I talked about Columbus many times.
neil degrasse tyson
Yeah, yeah, yeah.
joe rogan
It's horrific.
neil degrasse tyson
So, in one of the voyages, they went on some stretch of time and they didn't have food and they had Indians that they brought on board as well as some of their own crew.
And people were dying.
And so, at sea, what do you do with a dead body?
You throw it overboard, of course.
So, a person who's keeping notes said all the Indians they threw overboard Floated face down.
And all the Christians floated face up.
joe rogan
Oh, Christ.
neil degrasse tyson
I said, okay.
Okay.
I guess that could happen.
Statistically, perhaps.
I don't know.
But now we have his handwritten notes in his testimony of something that is completely fulfilling his own worldview's expectations of how things should be.
unidentified
Mm-hmm.
neil degrasse tyson
So in the whole sort of law and order chapter, I just pick all that apart and just try to say, you know, why not have jurors that are really good at data analysis?
How about that?
joe rogan
That would be nice, but that's really hard to find.
And then on top of that, if you are dealing with eyewitness testimony, what do you do?
Do you just throw everything out completely?
Or do you try to assess whether or not that person is capable of objective thought and reasoning?
neil degrasse tyson
No.
Because even people who are better at it are still flawed at it.
joe rogan
Right.
Especially under extreme duress.
neil degrasse tyson
Stress experience.
Correct.
As they've done many times in psychology class, the class is unfolding, and they stage some violent thing with an explosion, and then they say, write what you just saw.
And nothing agrees.
So, yeah, it's a challenge.
joe rogan
Which is the problem of conspiracy theories after big events like 9-11.
Like all the people that say they saw this and they saw that and I remember this and I remember that.
unidentified
Correct.
joe rogan
And you have these little sound bites of all these people and you piece them together like, oh my god, they planted bombs.
neil degrasse tyson
And there are also people who say before an earthquake.
joe rogan
They knew it was gonna happen.
neil degrasse tyson
They see all the animals running, and it's like, okay, you reported that after the earthquake happened, not like before.
joe rogan
But doesn't that happen during tsunamis?
Don't animals actually do go to higher ground?
I think that has actually been documented.
neil degrasse tyson
Okay, so I'm highly suspicious of whether that's true.
Because a tsunami, there's no way to know that.
Tsunami typically occurs from an earthquake way offshore.
And it's a very low...
Amplitude wave in deep water that continues to gain amplitude as the water gets shallower and shallower.
So that's why waves get bigger when they crash on the shores.
So as it comes to the shore, so if you're just an animal in the woods, if you're not on the shoreline, there's no way to know that.
joe rogan
I think they were talking about animals on islands and animals that do live closer to the shore.
And maybe there's an indication because the water pulls back.
neil degrasse tyson
Sure, I can recognize that, but if you're just an animal somewhere onshore, away from the coast, I don't really see that.
I need to see very good evidence for that, and not just someone's account of it.
joe rogan
Yeah, I don't know if they're talking about- This is my whole point.
neil degrasse tyson
People have accounts of all kinds of things.
Do you know, there's a whole other chapter called Risk and Reward.
Here's something.
Surely in your life you have taken an average of numbers before.
joe rogan
Tell me yes.
neil degrasse tyson
Lie to me even if it's not true.
Do you realize that the first time anyone ever did that to realize that maybe there's some interesting result here was after The invention of algebra, trigonometry, geometry, and calculus.
joe rogan
Really?
neil degrasse tyson
Statistics is just something that the human brain, it's just not natural.
It is completely foreign to us.
We don't know how to interpret simple random events because we want to give meaning to them.
You know the thing where you're in some other country in some other city and you meet someone like a childhood friend.
And you say, small world!
That's your first thought, right?
Small world.
Here's how to cure that.
Next time you're in a foreign city, Go up to every single person you walk by and say, do I know you?
And they'll probably say no.
I mean, know you personally?
They'll know you because you're a dude, but they know you personally?
No.
Just keep doing this.
And if they say, no, I don't know you, then say, big world.
Just do that.
You'll do that millions of times before you meet someone who you once knew.
And the proper statistics will then get recorded for that.
So no, it's not a small world.
It's a fucking big world.
And there are a lot of people in it who you don't know.
joe rogan
It's just very unusual when you meet someone in another country that you know from back home.
neil degrasse tyson
Well, if you do the math, there are a lot of things that people say are unusual where it would be unusual if you didn't.
joe rogan
Well, if you fly to England and you don't tell anybody you're flying to England and you run into a friend from back home, that's pretty unusual.
neil degrasse tyson
Look how often people say that it happens.
joe rogan
Well, we live in a strange world now.
neil degrasse tyson
That's precisely my point.
joe rogan
Right.
neil degrasse tyson
Okay, everybody you know has that story.
If you run the statistics on it, it would be odd if you went your life—presuming you have a normal life and you know people and your school was big and all of this, okay?
You didn't grow up in a farm with nobody—you didn't know anybody.
It requires some basic number of people.
So there's a lot of errors of statistics that we make of probability and statistics.
The sad part of it is there's an entire industry that has risen to exploit that fact.
And they're called casinos.
The fact that you could go to a roulette table and somebody's got a lot of money on seven.
I said, why do you have money on seven?
It's due.
What do you mean it's due?
Well, look at the previous roles because they'll show you the previous roles and seven hasn't appeared in 20 roles or whatever the number is they put.
So it's due.
No, it's not due.
This is a failure of the human brain to understand and interpret probability and statistics.
There are people who are going to roll dice, okay?
If they need a low number, they'll take the dice and like gently roll them.
If they need a high number, they'll throw them hard.
unidentified
This is crazy!
joe rogan
But those people are suckers.
There's other people that do understand statistics, and they kick them out of casinos because they count cards.
neil degrasse tyson
Only for those that are not purely random, like a roulette table, okay?
Or dice.
Right.
joe rogan
You think things like blackjack.
neil degrasse tyson
Correct.
You can tilt the odds in your favor a little bit and be systematic about it.
But I'm talking about pure probabilities.
The fact that someone thinks that a number is due.
joe rogan
Right.
neil degrasse tyson
Is itself, do you realize the American Physical Society, this is my physics peeps, that's our physics society.
1986, they were going to have their annual meeting in San Diego, and there was a hotel snafu, so they had to reschedule.
And so Vegas said, we'll take you.
The MGM Marina, which became the MGM Grand, we'll take you.
4,000 physicists said, okay.
4,000 physicists had their annual meeting in Las Vegas.
And let me tell you, K-12, is there even a course offered in probability and statistics?
You learn reading, writing, and arithmetic, not reading, writing, and probability and statistics, right?
It's kind of not there.
And if it's there, it's an elective, okay?
So, as a scientist, especially as a physical scientist, I take some form of probability and statistics every single year I am in school.
Different nuances and how data can be looked at and analyzed and put together and averaged.
The average that I told you about, you add numbers, divide by them.
That's one of a dozen kind of ways you can average numbers.
There are other ways.
You can have a statistically weighted average.
It depends on the needs, depends on the situation.
Point is, the physicist came to Vegas.
One week later, there was a news headline, Physicists in Town, Lowest Casino Take Ever.
Physicists were told to never return to Vegas.
joe rogan
Really?
neil degrasse tyson
Yes!
joe rogan
They were told to never return?
neil degrasse tyson
They were told.
Well, that might be apocryphal, but it was in the headline.
joe rogan
Really?
neil degrasse tyson
Yeah.
joe rogan
That's funny.
neil degrasse tyson
So these are people, these are my peeps, this is what we do.
unidentified
A little too smart.
neil degrasse tyson
We think about, it's not because we took advantage of the blackjack table, it's because they just simply didn't gamble.
joe rogan
Well, I'm the same way.
I don't gamble either.
I look how big the place is.
I'm like, how was this made?
By selling tickets to the buffet?
I don't think so.
I don't think so.
No, this is made from suckers.
neil degrasse tyson
Not.
joe rogan
Me and my wife went a few months ago.
neil degrasse tyson
Let's say you're winning in something.
You're in the one-armed bandit and you had a jackpot.
What do they do with you?
At that point, they see this is happening.
What does the house do?
joe rogan
They check the machine.
neil degrasse tyson
No, no, no.
joe rogan
They check you.
They give you free drinks.
neil degrasse tyson
No, they give you free drinks.
joe rogan
Yeah.
neil degrasse tyson
They got a comely server to come over to you and say, would you like a free cocktail?
joe rogan
Yes.
neil degrasse tyson
To stir chemicals into your brain to disrupt the little bit of objective reality that you're experiencing.
joe rogan
Release your inhibitions.
You're feeling lucky.
Are you feeling lucky, Neil?
neil degrasse tyson
Are you feeling lucky?
joe rogan
Yeah.
I don't feel lucky at all at casinos.
I feel stupid.
neil degrasse tyson
Oh, and another thing with the state lotteries, this is all in the risk and reward chapter.
State lotteries, do you know what most of the revenue, you know, it's a state money that goes into the coffers, tax coffers.
Do you know where most of that money is allocated in most states?
joe rogan
No.
neil degrasse tyson
It goes to education.
joe rogan
Oh, that's good.
neil degrasse tyson
You didn't know that?
joe rogan
No, that's great.
neil degrasse tyson
Yeah, it's cool.
So that makes you feel a little better like you're helping out your own state when you buy your state lottery.
Here's the thing.
Part of me wonders, okay?
Let me join you in a conspiracy thing here, okay?
Okay.
That's my conspiracy.
unidentified
Okay?
neil degrasse tyson
Am I allowed?
joe rogan
Yes, please.
neil degrasse tyson
Am I allowed one per year?
joe rogan
I'll give you all the ones you want.
I love a good conspiracy.
neil degrasse tyson
The conspiracy is they have to make sure that the school curriculum does not teach probability statistics.
unidentified
What?
joe rogan
What?
Because if they did- Wait a minute, wait a minute, wait a minute.
neil degrasse tyson
If they did, then no one would play the lottery.
joe rogan
So they allocate money to education with a specific mandate that you can't- No, I'm not saying that.
What are you saying?
neil degrasse tyson
Yes, I'm saying that.
joe rogan
Jamie's saying no, no, no.
unidentified
It's not like a law.
neil degrasse tyson
No, no, no.
unidentified
No, I'm just saying it's a little suspicious.
neil degrasse tyson
That the very knowledge of math that would undermine the ability of the state lottery to make money is not a required part of the math curriculum in kindergarten through 12. But you don't think that's why.
I'm just playing with it.
No, I don't really think that's why.
Right.
Okay, so I see what you were doing there.
You were assuming that I was totally in on this conspiracy theory and I have charts on my wall and websites devoted to it.
No, it just crossed my mind how odd it is that when you know enough about probabilities, you bet less.
And when you bet less, the revenue to the state would drop, and that's the revenue that would go to education.
So it has the power to plant the seeds of its own undoing.
And it doesn't do that.
I'm intrigued by that fact.
joe rogan
Just removing ourselves from the conspiracy theory aspect of it, do you think that it would be beneficial to teach probability and statistics to people?
neil degrasse tyson
Oh my gosh!
Look at how many bad decisions we make!
Because we think we have an understanding Of what is random and what is not.
There's the one, they did this, but actually their analysis was flawed, but the basis was well placed.
So the idea, you're playing a basketball game, and somebody hits a few shots in a row, he's got a hot hand, give it to them.
They don't have a hot hand.
It is the natural consequence.
If you're shooting 50% in a game, or 40%, and you take, I don't know how many shots, you take 30 shots, you can look at the probability that you'll have multiple shots in a row that are made.
And it's very high and it's very real.
So it's not something special happening.
It is the randomness of the statistics that's happening.
joe rogan
Okay, but this is talking about statistics, but from an individual basis.
Do you discount the idea that sometimes people feel really good and they have a very good sense of where the ball's going, where they're more loose or relaxed or more practiced, whatever it may be, and they're more accurate because of that?
neil degrasse tyson
If that's the case...
No, so people have good days, right?
joe rogan
Right.
neil degrasse tyson
Clearly.
So this is why that original analysis was slightly flawed.
Because a person can have more than what is typical shots in a row.
joe rogan
Right.
neil degrasse tyson
Okay?
And for that game, you could look at their data, and they would make 60% of the shots instead of 40% of the shots.
And if you make 60% of the shots, you then expect three in a row here, six in a row there, five in a row here.
In the...
In the random expression of having a 60% success rate in a basket, you expect intervals where you make multiple shots in a row.
That's my only point.
And that could be a good day for you because you're shooting 60%.
And I want to recognize that.
I'm going to hand you the ball if you're having a good day.
You can totally have a good day.
But at the end of the day, you're not sinking 20 here and none before it.
No.
The statistics maintain themselves in the game, unless you get injured or something, of course.
But my point is, we have such...
And I don't want to blame people for this.
If it was natural to think statistically about the world, it would have been the first branches of math we would have ever discovered.
But it wasn't.
It was like 1753. Sounds like a long time ago.
But it's 50 years after calculus was invented.
After calculus, which is not even taught in school.
joe rogan
Not long ago at all, really.
neil degrasse tyson
Correct.
There's a simple paper on the benefits of taking the mean, mean is average, of observations in astronomical data.
That's what an astronomer did it.
First to take a mean.
And this is just...
So that tells me we are victims of our own brain wiring.
And it takes many years to undo that wiring or to see through it so that you are not...
You know, and it prevents you from seeing other things, okay?
joe rogan
How so?
neil degrasse tyson
Do you realize last year we lost as many people in the United States to traffic accidents...
As we did in all the years we fought in Vietnam.
Look at the effort we put up as a country beginning maybe 1967, certainly 68, to stop the carnage And that's just the American deaths, not to mention the millions of deaths of the Vietnamese themselves, North and South.
Point is, our reactions to statistics are very different depending on what caused it.
And I'm intrigued by that.
I don't have a good understanding of it.
Any laws that treat it are going to have to fold in people's emotions.
Here's an example.
You shoot deer with your bow and arrow.
There's a certain number of deer deaths and human deaths by cars hitting deer in the roads, especially in suburban, rural places, okay?
What do you do about this?
What are you going to do?
joe rogan
Get a truck with a big-ass bumper.
That's what they do out here.
neil degrasse tyson
The Joe Rogan solution.
joe rogan
That's the Texas solution.
You ever see those guys that work on ranchers?
neil degrasse tyson
Make sure your truck has significantly more mass than the deer.
joe rogan
No, they have specific bumpers that they build to save people's lives.
neil degrasse tyson
Right.
And, of course, this is what the old locomotives had if there were cattle on the – you ever see that pointy front on locomotives?
joe rogan
Yes, exactly.
neil degrasse tyson
Yeah, that was to pry cattle on it so it wouldn't roll over the cow and derail the thing.
So what do you do?
Do you accept – The hundred deaths a year in your county, whatever, human deaths.
No one's counting deer deaths here, right?
Or do you find something...
joe rogan
Get yourself a big-ass bumper.
neil degrasse tyson
Oh, there you go.
Big-ass bumper.
joe rogan
Deer killer bumpers.
Look at those suckers.
neil degrasse tyson
I like the Ford F-250 right there.
joe rogan
That's what I'm saying.
Look at that one.
The Ford F-250, that red one, that's what I'm talking about.
neil degrasse tyson
The problem is if the center of mass of the deer is above the level of that bumper...
joe rogan
But it's not.
neil degrasse tyson
Well, for elk it would be.
For moose it would be.
My wife grew up in Alaska.
joe rogan
No.
neil degrasse tyson
Yes.
joe rogan
No, not a 250. F-250?
Center of Massive and Elk?
neil degrasse tyson
Moose.
joe rogan
Moose is a different thing.
neil degrasse tyson
I saw a moose.
joe rogan
When you see them for the first time, you're like, how is that real?
The first time I saw a moose, I was in British Columbia, and I saw it.
It was like the scene in Jurassic Park where Jeff Goldblum gets out of the Jeep, and he's like, Yeah.
neil degrasse tyson
It's like, who invented that?
Right, right.
joe rogan
Look at the size of that thing.
neil degrasse tyson
So if you're under the center of mass, then it will just roll up and crush your windshield.
Yes.
So you have to watch out for that.
joe rogan
It will go through your windshield.
neil degrasse tyson
Yeah, yeah, yeah.
joe rogan
It's horrific.
neil degrasse tyson
So here's my point.
There's a group, I forgot where, somewhere in New England, who did a study.
And the study was, if you have 100 deaths a year, we can drop that to maybe 30 deaths a year.
How?
By introducing...
The natural cat predator to the deer.
So it would be like the puma or bobcat, one of these sort of mid-sized cats that hold the deer as their quarry.
And they ran some models of how this would go.
And you could drop the number of human deaths by a factor of three.
Because still some deer would wander onto the road.
But You'll lose about 10 children a year.
They'll just snatch your kid out of the backyard and eat your child.
So look at these numbers.
You killed 100 people in their cars, or the deer killed 30 people plus 10 children.
No, no.
The deer killed 30 people.
The bobcat kills 10. And the bobcat might kill an adult.
Not bobcat.
unidentified
Mountain lion.
neil degrasse tyson
Mountain lion.
Or whatever was native in the region long ago.
And so they did a study.
And the point is, you could not bring that suggestion forward.
joe rogan
Right.
neil degrasse tyson
Because the government would be introducing an animal that killed your children, But no one's looking at the hundred people that were, whatever the numbers were, it was a factor of three or so.
joe rogan
Do you know there's another solution?
neil degrasse tyson
The correct numbers are in the book.
No, I'm just giving this as an example.
joe rogan
I understand.
neil degrasse tyson
We're not equipped to fold our emotions with the data to arrive at a solution That would save the most lives.
joe rogan
I see what you're saying.
There is a technological solution that they've come up with.
There's a device that they put at the front of the car that makes a very certain sound that alerts dear to the presence.
unidentified
I've heard about that.
neil degrasse tyson
It's right on the edges of the...
I've heard about that, but I haven't read about it...
20 years ago or so.
I haven't heard much about it since.
joe rogan
I don't know how effective it is.
neil degrasse tyson
The air going through it makes a kind of a siren effect.
joe rogan
Is that what it is?
unidentified
Yeah.
neil degrasse tyson
That's when I last remembered it.
unidentified
Yeah.
joe rogan
Well, whatever it is, it develops some sort of a sound that the deer can hear and they avoid it.
But...
They have a problem with headlights.
neil degrasse tyson
I was in Alaska, and there was a deer and a grizzly bear.
Must have been 300 yards away.
Way down in the valley.
And the deer noticed it.
And it was eating, but it was eating very cautiously, always looking to the bear.
And I'm saying, if it could notice a bear 300 yards and be cautious of it, Why can't it know a Ford 250 barreling down a road?
joe rogan
Because it's not natural.
neil degrasse tyson
Well, figure it out!
It's a mammal that's got a brain!
joe rogan
That takes forever.
neil degrasse tyson
Let me get angry with the deer for a second.
And how come we haven't killed all the stupid deer by now, so the ones that are left are the ones that recognize that cars killed them?
joe rogan
Because they're all stupid.
They just have really good senses.
They have senses that are designed to avoid predation.
neil degrasse tyson
But they're living with us now.
Mice and rats figured out how to coexist with humans.
joe rogan
Rats are very intelligent.
neil degrasse tyson
They figured this out.
joe rogan
Yeah, but deer don't know what to do with headlights in cars.
It's a completely unnatural thing.
neil degrasse tyson
So everyone that doesn't, they die.
And the ones that have a little bit of genetic variation that figures it out, they'll survive.
joe rogan
Sort of.
Because then they get horny.
The problem with deers, if you look at the number of deaths...
neil degrasse tyson
So I don't know anything about the sex life of deer.
joe rogan
I do.
neil degrasse tyson
Okay.
joe rogan
One of the things that happens...
neil degrasse tyson
Don't tell me how you know.
joe rogan
The uptick.
Well, the rut.
When deer rut is when you hunt them, and one of the things that happens during the rut is they get ridiculous, and they just run out into traffic.
neil degrasse tyson
Okay, they can't even control themselves.
joe rogan
They chase does into the street.
That's oftentimes does.
neil degrasse tyson
The male deer chase the female deer.
joe rogan
Yes, because they're just chasing them.
The females are just trying to get away, and they just run out into traffic.
That happens.
Or the male is trying to chase the female, and all he's got on his mind is he's got tunnel vision, and they just, boom, gets hit by that F-250.
neil degrasse tyson
Speaking of deer, By the way, my sister drives an F-250.
Or is it a 450?
Is there a 450?
No, she drives a 350!
Excuse me!
joe rogan
Oh, she has a Dually?
neil degrasse tyson
Yeah, she's got one where the tires can do separate things.
Oh, okay.
Yeah, she's serious.
Don't mess with my sister.
joe rogan
Okay, is your sister out there off-roading?
What is she doing with that crazy truck?
neil degrasse tyson
She likes being badass when the time comes.
joe rogan
I like the way she thinks.
neil degrasse tyson
But she doesn't hunt, so it's missing half the equation there.
So, on the subject of deer...
In the chapter on gender and identity.
So I go there, gender and identity, because it's a very hot topic.
joe rogan
Yeah.
neil degrasse tyson
And I just apply some rational thinking to it.
Do you know about Santa's reindeer?
Do you know about them?
joe rogan
Sure.
I know very much about them.
neil degrasse tyson
Oh, you do?
joe rogan
Yeah.
neil degrasse tyson
Okay.
So do you know that...
joe rogan
The caribou.
neil degrasse tyson
Yes.
Yeah, caribou, correct.
joe rogan
Yeah.
neil degrasse tyson
And, well, you can domesticate the caribou.
And when you do...
Then both the boys and the girls have antlers.
joe rogan
Okay?
Well, that's just the fact of all caribou.
neil degrasse tyson
Oh, all caribou.
Excuse me.
But sorry, the domesticated ones are called reindeer, but they're derived from the caribou.
Correct.
So now watch what happens.
So, as you may know, the male deer lose their antlers in late October, early November.
joe rogan
Depending upon where they're at.
neil degrasse tyson
Unless you castrate them.
You castrate them and they'll keep their antlers.
But otherwise they drop their antlers.
joe rogan
Right.
neil degrasse tyson
Before winter begins.
joe rogan
Generally not.
neil degrasse tyson
No, I don't agree with that.
joe rogan
Well, it depends on the animal, but a lot of them keep it until almost spring, and then they drop and they grow back very quickly.
neil degrasse tyson
That's nothing of what I've read or learned of this animal.
joe rogan
Or just caribou?
From deer?
neil degrasse tyson
No, caribou.
Just caribou.
Specifically.
joe rogan
Okay.
neil degrasse tyson
The ones that became Santa's reindeer.
We're not talking about the deer in Central Texas.
No.
joe rogan
They dropped them in the winter.
neil degrasse tyson
They dropped them in November.
Okay?
joe rogan
The female don't.
neil degrasse tyson
The female don't.
So all that means is all eight of Santa's reindeer are female.
Which means Rudolph has been misgendered.
joe rogan
Interesting.
Well, do you know where the myth of Santa's reindeer flying comes from?
neil degrasse tyson
I think it's from mushrooms, isn't it?
joe rogan
Yeah, Amanita muscaria mushroom, which looks like Santa Claus.
neil degrasse tyson
Yeah.
joe rogan
That's it.
neil degrasse tyson
With the red and white dots.
joe rogan
And they love those things.
They love the Amanita muscaria mushroom to the point where when people are doing mushroom ceremonies and they go outside to urinate...
neil degrasse tyson
To drink the pee.
joe rogan
Caribou will knock you over to get to your urine.
neil degrasse tyson
Yeah, that's crazy.
joe rogan
If you have domesticated caribou, they will knock you over to get to the urine because they smell the Amanita muscaria and whatever.
It's not psilocybin.
neil degrasse tyson
It has to be such a major...
I'm trying to imagine how high I want to get to drink someone else's pee.
joe rogan
Well, caribou are not that wise, nor are they educated, nor do they even understand the concept of urine.
Whatever the psychoactive compound, well, their sense of smell is preposterously intense.
I mean, we can't even imagine what a deer can smell.
They can smell you hundreds of yards away.
I mean, I've seen deer go like this a hundred yards away, and then they bolt because they smell you.
They catch your wind.
Yeah, they're amazing.
neil degrasse tyson
Here's a mystery that I've always had.
To this day.
Because dogs have very acute sense of smell as well.
joe rogan
Yeah.
neil degrasse tyson
That's how you say that.
If you just say, dogs smell good, you don't know what that means, right?
Do they smell better than we do?
Right.
It's an ambiguous sentence.
joe rogan
Right.
neil degrasse tyson
So they have an acute sense of smell.
So if they smell so acutely, why do they get within like a half inch of each other's butt?
joe rogan
Because they want to smell each other.
neil degrasse tyson
But you could smell that 100 yards away?
joe rogan
Yeah, but they want to smell everything.
They want to smell the hormones.
Yeah, well, they're intensely attracted.
neil degrasse tyson
Okay, so it's so good.
joe rogan
Yeah.
neil degrasse tyson
Let me get up on it.
joe rogan
Yeah, they want to know if you're feeling aggressive, if you're in the heat.
They want to know all those things.
neil degrasse tyson
Yeah, I never had that urge to do that with other humans.
joe rogan
You know, a bear can smell somewhere in the neighborhood of nine times greater than a bloodhound.
neil degrasse tyson
Mmm, so we should domesticate bears and track down.
joe rogan
Good luck with that.
neil degrasse tyson
By the way, have you seen a bear?
You've got to be able to find this.
I saw it on social media.
There's a bear walking down a highway, and there's a tipped over traffic cone, and it looks at it, and then it writes it back up and keeps walking by it.
Wow.
And I say to myself, because I have a chapter in here called Body and Mind.
There it is.
Check this out.
Just watch.
It's a black bear.
joe rogan
He's like, this looks wrong.
neil degrasse tyson
Yeah, it looks wrong.
Okay.
By the way, you found this video really fast.
Thank you for this.
joe rogan
I think that's a grizzly bear.
neil degrasse tyson
Oh, he's got the lump on the neck?
joe rogan
Yeah, the way he looks.
That's pretty crazy.
neil degrasse tyson
Yeah, that's grizzly.
That's a total grizzly bear.
And it keeps going.
Didn't even look back!
joe rogan
What do you think's going on with that?
neil degrasse tyson
I don't want to say that's evidence of intelligence so much as it's evidence of more going on inside the animal's head than any of us would have previously ever credited.
In another example, and I get this example in body and mind again, there's a magpie Bird, who there's a bottle of water in some playground area, park area, and it goes up to the bottle of water and it dips its beak in to drink from it.
Okay, here it is.
See this?
Okay, it goes in and drinks from it to watch.
It's going to drink.
But the problem is there's a limit to how far its beak can reach inside of it.
And so it gets a stone that fits inside the bottle, which raises the water level so that its beak can continue to drink from it.
This is some Archimedean crazy stuff going on.
joe rogan
It really is.
neil degrasse tyson
The magpie, by those in the know, is ranked among the smartest of birds.
And this is doing something I think humans wouldn't even think to do.
joe rogan
Probably many humans.
neil degrasse tyson
Right.
And so, do you remember, how did they teach you where humans were in the tree of life when you were in school?
Like, we were the smartest or the biggest brain.
How did they describe it to you?
joe rogan
Yeah, we're the top of the food chain.
neil degrasse tyson
Okay.
And what do they say about our brains?
Just tell me in your...
joe rogan
Well, it's the size of our brains that makes us so superior.
neil degrasse tyson
Okay, but...
joe rogan
But then you look at a magpie.
neil degrasse tyson
Yeah, but dolphins' brains are bigger, so...
joe rogan
Yeah, 40% larger.
neil degrasse tyson
Okay, so then, therefore, what is, you know...
Whale brains are bigger.
If there are other animals with bigger brains and we want to stay at the top, what do they say about those other animals?
joe rogan
I don't know, what do they say?
neil degrasse tyson
No, I'm saying, okay, so you know what they did?
joe rogan
They say they're inferior?
neil degrasse tyson
So what they did was say, they say, oh, no, we don't have the biggest brain, oh, but brain to body weight ratio, then we're the highest, okay?
joe rogan
Is that accurate with dolphins?
neil degrasse tyson
Yes, so our, because they're bigger, much bigger creatures than we are, and when you divide the weight of the brain by the weight of the body, we win.
joe rogan
Right.
neil degrasse tyson
We beat out Whales, we beat out dolphins, we beat out elephants.
Then there are those who are fans of those who say, well, you want to do it lean weight because the dolphins and whales have a lot of blubber and the brain is not having to control the blubber.
So cut away the blubber.
That boosts them, but they're still not as high as us.
So we walk away saying, we're at the top.
However, what they did not say, which I had to, 40 years later, I learned this, That we do not have the highest brain-to-body weight ratio among animals, only among mammals.
The magpie has a higher brain-to-body weight ratio than humans do, as do all other mid-sized birds, like crows, owls, eagles, these folks, okay?
Mm-hmm.
We all have a higher brain to body weight ratio than humans do.
So that rule that put us at the top was specifically for mammals.
And I'm angry that I didn't think to hear how specific that was when I was taught that in eighth grade.
joe rogan
Isn't our understanding of like crows using tools very recent, like within the last hundred years?
neil degrasse tyson
All I can tell you is any animal that we have ever got to study in more detail than we previously did has shown to be more intelligent than we ever gave it credit for being.
And you know who has the biggest brain to body ratio of any creature on earth?
joe rogan
Who?
neil degrasse tyson
Some species of ants really 15% of the body weight is their brain And it's kind of obvious some of them like the whole front section is their head, right?
It's kind of in retrospect It's kind of obvious and ants are very busy doing some complicated things and we don't know what they're doing especially leaf cutter ants that they're busy carpenter ants leaf cutting ants and crossover into termite land I don't know how big their brains are, but they're busy building stuff.
joe rogan
And they work in communication with each other somehow.
neil degrasse tyson
And they communicate.
One of my favorite cartoons was two dolphins swimming together, and there's a human up, you know, it's like one of these water parks, right?
And one dolphin says to the other, they, speaking of the humans that are up on dry land, they face each other and make noises, but it's not clear they're actually communicating.
So, I'm just saying, we have a picture of an ant, remember?
Close-up of an ant.
Yeah, that recently released this image, I think.
Yeah.
joe rogan
Jesus Christ.
neil degrasse tyson
So...
joe rogan
What a horrific demon that would be if it was large.
neil degrasse tyson
Insects with so much detail on their bodies.
And to say, well, we're at the top.
Really?
I got one for you.
How much at the top are you?
Do you realize one slice of your lower intestine, your colon?
One centimeter slice...
Lives and works more microbes than the total number of humans who ever lived.
So, ask yourself, what are you to those microbes?
Are you Joe Rogan?
No, you are an anaerobic vessel of fecal matter in which they thrive.
joe rogan
And without them, you don't exist.
neil degrasse tyson
Well, you don't digest your food, first of all.
Second, you want to keep them happy because if they're not happy, then they're in charge.
They send you to the nearest toilet as fast as can be.
So part of a cosmic perspective on this world is looking at things in a way that decentralizes who and what you are relative to everything else.
And you get a much more honest account of how things work, how they're put together.
joe rogan
That's very hard for people to really grasp.
unidentified
It's an ego.
joe rogan
You're actually an ecosystem.
neil degrasse tyson
Yes.
Yes.
And what is the number?
Some percent of your total body weight is the weight of other living things, especially what's alive and thriving in your gut.
You're just carrying them along.
joe rogan
That's the case with all organisms, though.
We like to think of organisms as being individuals, but they're actually hosts.
neil degrasse tyson
I don't think...
Well, not all.
joe rogan
Not when you get down to single cells.
neil degrasse tyson
Not single cells, but others, yeah.
A lot of symbiotic relationships going on.
joe rogan
Oh, yeah.
neil degrasse tyson
And so you can have a cosmic perspective that's not just the cosmos.
joe rogan
Yes.
neil degrasse tyson
Cosmic perspective just here, life on Earth.
And, you know, they talked about the overview effect where the astronauts, you probably had a few astronauts here as your guest.
joe rogan
Looking down.
neil degrasse tyson
Yeah, you look down.
I prefer the view from the moon.
I'll take it from orbit.
joe rogan
Are you going to do any of those?
Like if they let you up on the Jeff Bezos spaceship?
They send people up there all the time now, right?
It's fairly regular.
neil degrasse tyson
I'm an astrophysicist.
joe rogan
You're not interested?
neil degrasse tyson
No, hear me out.
So take Earth and shrink it down to like a schoolroom globe.
So now we can think of distances relative to that.
And ask, how high up did Bezos and Branson go?
Okay, so here's the school room, but how far away would you say?
joe rogan
Quarter inch.
neil degrasse tyson
You say quarter inch?
Okay, they went the thickness of two dimes.
joe rogan
Oh.
neil degrasse tyson
And a boy who jumped out of a balloon some years ago?
Yeah.
What's his name?
Felix Bumgardner?
unidentified
Mm-hmm.
neil degrasse tyson
Thickness of one dime.
So this idea that they're going, oh, I see the curvature of the Earth.
No, you don't.
You don't.
I'm sorry.
joe rogan
Jeff Bezos doesn't see the curvature of the Earth?
neil degrasse tyson
You will see the edge of the Earth, but ask how far away is your horizon when you're only that high up.
You can just look at that.
Go to the Schoolroom Globe.
Go to...
Dime thicknesses up, and then draw a line to ask, how much of Earth do you see?
You'll see a circle, but that's a circle cookie cut out of the larger sphere.
joe rogan
So it's a perspective issue.
neil degrasse tyson
It's a perspective issue.
And by the way, the images when they showed Felis Bumgarner, where he's prepared to jump, you see this curved earth.
That's a fisheye lens, dude.
Okay?
Fisheye lenses take horizontal lines and bend them.
It's convex when you're above the midplane of the photo.
joe rogan
In order to gather in more of the image.
neil degrasse tyson
Correct!
That's the only way you can distort it to fit it onto a flat plane, because it's looking at a full sort of 360, well, 180, and it's trying to get it in.
But what happens if you take that horizontal line, the horizon, and put it below the midplane of the camera?
It then bends the other way.
Ben's the other way.
In fact, I have a tweet that did this.
Look for Felix and throw some keywords in there with my Twitter handle, and I have the example of the photos.
So, no, he didn't see the curvature of the Earth, but you think he did, and he's high up, and what do we need NASA for, right?
He's one dime thickness.
Elon Musk authentically goes into orbit, because they didn't go into orbit.
They went up and fell back to Earth.
He authentically goes into orbit.
So he is a centimeter.
Well, not even.
Let me see.
Yeah, a little less than a centimeter above Earth's surface.
The folks who really saw Earth were the folks that went to the moon.
We went to the moon nine times, three astronauts a pop.
27 astronauts have seen Earth from the moon.
And that'll change you.
Do you know Apollo 14 astronaut, Edgar Mitchell?
I have a quote from him that opens this book.
And that's all you have to read because the whole book issues forth from that quote.
Here it is.
Edgar Mitchell, Apollo 14. You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.
From out there on the moon, international politics looks so petty.
You want to grab a politician by the scruff of the neck and drag him a quarter million miles out and say, look at that, you son of a bitch.
joe rogan
Edgar Mitchell also believes some wacky stuff.
Did you know that?
neil degrasse tyson
Yeah, I've spoken with him about it, and he was one of the, was he co-founder of the Noetic Institute?
He was a big fan of the possibility that there was a deeper level of consciousness, and I don't think it involved drugs, but just that there was a deeper level of consciousness That the brain might be capable of if subjected to the proper influences and He told me how he came across this.
Okay, I'll tell you They're on their way back from the moon and they're in the capsule and the capsule rotates It helps to stabilize it among other reasons for that happening and he happened to be positioned in the capsule for three days and Where the windows to the capsule were aligned with the plane of the solar system.
Which means every time the capsule rotated, what came in and out of view was the Sun, the Moon, Earth, and all the planets.
And so he's there for three days watching this drift by.
And he felt like he had descended or ascended into a trance state that was beyond what he had ever experienced here on Earth.
By normal things you encounter just being a human on Earth.
And that led him to wonder whether this was an achievable state by some other means By some other forces that you could emulate here on Earth.
And because he experienced that and I didn't, who am I to say?
I'm not going to judge that.
joe rogan
He believed in psychokinetics.
He believed people can do things with their mind.
He had a lot of very strange things that he was interested in.
neil degrasse tyson
I think the cleanest way to say that is he believed there was much more capacity of our mind than we had previously tapped.
And that opens up the gates to all these other things.
But I was just sharing with you the experiential origins of why he thought that way.
But the point is that that can change you.
And in the chapter Earth and Moon, I talk about cosmic perspectives.
As you ascend, the Earth does not look like the schoolroom globe.
Color-coded countries?
You know, only as an adult did I look back on that and I say, you trained me.
From elementary school to know who my enemies are and who my friends are by color-coding contiguous land masses on a globe to teach me about the planet Earth.
joe rogan
But they weren't trying to do that.
neil degrasse tyson
They were trying to explain- It's a consequence of it.
joe rogan
Geography.
neil degrasse tyson
I knew who the evil godless Soviet Union was.
joe rogan
Right.
neil degrasse tyson
Okay?
Their country was painted red.
All right?
Not ours.
I knew this even if it was not on purpose.
It had a subliminal effect.
And when you go into space, the country borders go away.
Except for two places.
There are two places.
You can still see two borders from space.
One of them in the daytime.
You can see the border of Israel with surrounding deserts.
Because Israel irrigates.
And so it's green.
And the surrounding areas are brown.
You can see that from space.
Another border, which you can see from space at night, is, of course, North and South Korea, right there.
And that's punched up.
I mean, if you were in the dead of night, You don't know the difference between the ocean and the land as your sightline crosses North and South Korea.
If you look at the GDP per capita differences between Israel and surrounding nations and South Korea and North Korea, it's factors of 8, 9, 10, 12. Space can reveal economic inequities in at least those two places, which is itself kind of a stunning fact.
So I want to tell Elon, you're now neighbors with him, right?
Get him back here and say, Elon, build a bus, a space bus.
We have an Airbus.
Why not a space bus?
A space bus where you put all the warring leaders And have them send them to the moon, have them look back on Earth.
Say, you know, we're fighting over that border.
We are?
unidentified
What?
joe rogan
Once they came back down, I think they'd just go right back to work.
neil degrasse tyson
You think so?
joe rogan
I just went to the Keck Observatory on Wednesday.
neil degrasse tyson
Nice.
joe rogan
It was amazing.
neil degrasse tyson
Hawaii.
unidentified
Yeah.
neil degrasse tyson
Big island.
Very nice.
Did you go to the base camp or all the way to the top?
joe rogan
The base camp.
neil degrasse tyson
Yeah.
joe rogan
I went specifically there because I had an experience there.
About, it was six, 17 years ago, I went there and I caught it on a perfect night where the moon wasn't out and it was phenomenal.
And the view is so astounding.
There's so many stars.
You see the Milky Way in such clear detail that you have a totally different perspective of the cosmos.
And you feel like you're flying through space with a windshield over your head, like you're in a spaceship.
neil degrasse tyson
You know, there's some other...
My entire PhD thesis involved mountain-going.
It's a lost...
Ritual, because now we'd have what's called service observing.
You just write in what things you want to observe on what nights for how many hours, and then they send you back the data.
There used to be a pilgrimage to the top of a mountain, and you'd live nocturnally, and you'd go to them and be up all night with the telescope and the universe.
There's a certain almost spiritual connectivity that When it's just you alone.
And there are moments that mountains are high up enough so that if clouds roll in, you're above the clouds.
joe rogan
We were above the clouds.
neil degrasse tyson
You're above the clouds.
This is what makes it especially spooky, magical, mystical, Mount Olympus-like.
Because you're on the top.
There's no other land.
It's just clouds.
So it's you, the tops of clouds, And the universe.
joe rogan
Yeah.
neil degrasse tyson
Communing with the cosmos.
joe rogan
Just the view of it is so astounding.
neil degrasse tyson
And many people who go to Australia and say, oh, you've got to see the southern skies.
What they don't know when they say that is any clear sky anywhere in the world will get you that.
joe rogan
Yeah.
neil degrasse tyson
In the southern hemisphere, only 15% of humans live there.
So there's essentially no light pollution anywhere there.
85% of all humans in the north, you're hard-pressed to find a completely dark sky in the north, leaving you to think that there's something magically beautiful and different about the southern sky.
You're observing the northern sky.
Hawaii's like 15 degrees north, so it's a lot of the southern sky as well.
Point is, you have the best observing site in the world.
Which is why they wanted to put a 30 meter telescope there and there's some conflict with the indigenous groups regarding that and whether the mountain is sacred and in what ways it's sacred and the like.
And so that's still going on, last I checked.
But...
I'm not surprised and I'm delighted that you had that experience.
And now you know how I feel when I look up.
I was baptized, emotionally, psychologically baptized with the night sky in New York City's Hayden Planetarium.
Because as a city kid, I grew up in the Bronx.
We don't have a relationship with the night sky.
We might see the moon and an occasional planet.
The setting sun, that's it.
Couple of dots for stars.
That's it.
You see the tall buildings.
Back then there was air pollution, light pollution.
So my first night sky was the Hayden Planetarium.
And to this day, I was nine years old.
To this day, when I go to mountaintops, just as you experience, and I look up, I said, this is so beautiful.
It reminds me of the Hayden Planetarium.
joe rogan
That's funny.
neil degrasse tyson
I know that's messed up, but that's how I feel.
And you've got a sky here with meteors.
I'm loving it, man.
joe rogan
Shooting stars.
neil degrasse tyson
I'm loving it.
joe rogan
Yeah.
The view that I saw on Wednesday was not as good as the view that I saw, whatever it was, 16, 17 years ago.
neil degrasse tyson
Wait, wait.
Who laid out these stars?
joe rogan
Oh, it's just there's LED panels.
neil degrasse tyson
You didn't call me.
joe rogan
No, they're not accurate.
They're just dots.
neil degrasse tyson
Dude.
All right.
At least you have stars.
joe rogan
In my old pool in California, I had the star system of where, like, you know, I was born in August.
So it's the constellation Leo.
neil degrasse tyson
When you were born?
joe rogan
Yeah, when I was born.
Okay.
Embedded into the ground of the pool.
neil degrasse tyson
All right.
There you go.
There you go.
joe rogan
Allegedly.
You know, if they're asking me to verify, I'm like, wow, it looks like stars.
But that view of the Keck Observatory, just even from the base station, it's so stunning that it does reset your understanding of where we are.
And it makes you angry that we have so much light pollution that people are denied that.
Because I think it changes the way people view our relationship with the cosmos.
neil degrasse tyson
In fact, it goes even deeper than that.
But let me...
I want to quickly comment that there is an entire indigenous community in the world that is very concerned about the loss of very dark night skies because so much of the culture Relates to that night sky as part of what it values and what it passes down from one generation to the next and it goes beyond just the light pollution because now folks like your boy Elon Is
launching And I don't like the fact that they use the word constellation to refer to satellites.
Because that's my word.
That's my people's word.
Constellations.
They're actual stars.
Not moving hardware.
We got people talking to people.
I can connect you.
No, no.
We're friends.
joe rogan
You're using the wrong words.
neil degrasse tyson
I feel completely at home.
He's on the spectrum a bit.
I'd say one out of six of my colleagues is probably on the autism spectrum.
In retrospect, now that I look at, once you learn what the spectrum is, there used to be Asperger's and then they folded that in.
You know, there are colleagues who just would not relate to another person or a camera, but they were graded in their lab and in the things.
And so you say you're just not socialized.
No, there's something else going on in there.
joe rogan
Can I ask you a question about that?
neil degrasse tyson
Oh sure.
joe rogan
Do you think that that is an evolutionary advantage that in some way people are developing in this manner so that they can concentrate on things like technology, like astrophysics, like these very specific things that require immense amounts of concentration?
And extreme focus.
Do you think there's possibly that human beings are developing in that way, specifically to accentuate our ability to innovate?
neil degrasse tyson
So it would be very hard to draw that conclusion as some kind of modern force of evolution, because for that to be the case, What would have to happen is those who had this sort of autistic level of focus, so high functioning autism, they would have to be making more babies than other people.
joe rogan
Well, Elon is.
He's out there doing his part.
neil degrasse tyson
So they'd have to be making more babies relative to everyone else to affect the evolutionary path of modern civilization.
And it's not clear that that's what's actually happening.
So we have to ask, did that have any value historically?
I mean, in the history of the evolution of our species.
So, in the chapter Body and Mind, I go over the variations that exist within our species.
Huge variations in height, in weight, in speed, in all kinds of things.
And you can ask, well, then what is normal?
The day that we control the genome, is there going to be some place somewhere where there's a normal human and you're going to take your genome that you're about to control in your unborn child and say, let me adjust it so that it matches this so that all your senses are working as they're supposed to and all the proportions.
Is that the future?
We should ask that.
Because if that's what you're going to do, you're going to homogenize the species.
Okay?
Do you realize, I have a run here of content.
I have a run of descriptions of what people have accomplished, okay?
So, for example, there's a guy growing up, he wanted to play basketball, okay?
And he wanted to be a professional basketball player.
So he worked really hard at it.
And he just wasn't tall enough.
So he said, you should give it up.
But he stayed with it.
Stayed with it.
He said, no, basketball is for tall people.
You're not tall!
Okay?
He now plays for the Harlem Globetrotters.
His name is Hotshot.
What's his last name?
joe rogan
Well, Muggsy Bogues is a great example of that, right?
neil degrasse tyson
No, this guy is four feet five.
Whoa.
Yes.
He's a genetic dwarf.
People told him he can't play basketball, and now he's one of the most popular basketball players.
There he goes.
unidentified
Wow.
neil degrasse tyson
Okay?
Swanson.
Hotshot Swanson.
Okay?
joe rogan
Well, there kind of seems like there'd be an advantage of being that small so you can move around that quick.
neil degrasse tyson
I'm making a different point.
Yes, that's part of the point.
The point is, when you look at someone and they're not, quote, normal, and then you start listing what you think they should not do in life.
Constraining the options that maybe they have ambitions that are greater than anything you imagined.
And so...
There's a letter.
There's a letter beautifully written Someone took a voyage on a steamship in 1915. And I reproduced the letter in here.
Beautifully written.
And this passenger was given a tour of their steamship, okay, by the captain.
And this letter, I can't find it in here, but it's beautifully.
I mean, is there time for me to read something?
joe rogan
Sure.
neil degrasse tyson
You have plenty of time.
I got to read it.
joe rogan
We have all the time in the world.
neil degrasse tyson
Give me a second here.
Talk among yourselves.
What?
unidentified
Let me see.
H-A-J-G.
neil degrasse tyson
I got it.
unidentified
Okay.
neil degrasse tyson
There it goes.
Okay.
Here's a letter.
unidentified
Okay.
neil degrasse tyson
Okay.
Again, this is in the body and mind chapter where we explore Here it is.
I had the wrong ear.
How about a letter written on April 10th, 1930 to Captain Von Beck of the US Line's SS President Roosevelt?
That's Teddy Roosevelt, of course.
The captain had given a tour of the bridge to a passenger who later that day waxed poetic About the experience.
Again, I stood with the captain on the bridge, and he was quiet and composed in the presence of a million universes, a man with the power of a god.
In imagination, I saw the captain standing on the bridge, gazing into the wide canopied heavens and seeing the darkness sprinkled with stars, systems, and galaxies.
That passenger was Helen Keller.
A 1904 graduate of Radcliffe College.
Okay?
So, what...
My point is...
And I have other...
There's a whole run of pages of things...
And there's a whole description of Hotshot here.
Okay?
From the Harlem Goat Trust.
My point is, the moment you homogenize and, quote, normalize who and what humans should be...
You have cut off so much of what has enriched civilization simply because people were different.
joe rogan
Yes.
neil degrasse tyson
Simply because.
unidentified
Yeah.
neil degrasse tyson
And so, if everybody's the same, what kind of world?
I don't want to live in that world.
Give me a different world.
joe rogan
Do you worry that- I got another one here.
unidentified
Please.
neil degrasse tyson
One more, okay?
unidentified
Okay?
neil degrasse tyson
You probably know this, but those who don't know the name, hold off on it, okay?
Here it is.
Jim Abbott.
You know who Jim Abbott is?
Okay.
Some people won't, but here it goes.
Jim Abbott wanted his whole life to be a professional baseball player, a dream shared by many American boys.
Jim wanted to be a pitcher in the major leagues.
He succeeded and played for many teams, chalking up a mixed record of wins and losses, but on September 4th, 1993, while playing...
For the store read...
joe rogan
I don't remember.
neil degrasse tyson
New York Yankees!
Dude!
joe rogan
I thought it was the Mets.
neil degrasse tyson
No!
He pitched a no-hitter.
That's when no batter gets a hit in the entire game.
There have been about 320 no-hitters in Major League history out of 220,000 games played.
Due to a congenital birth defect, Jim Abbott was born without a right hand.
Is Jim Abbott disabled?
Is he?
He pitched a fucking no-hitter for the New York Yankees.
What I'm saying is, obviously not everyone who has a disability will achieve this way.
Don't get me wrong here, but what I want to say is...
Look at what people would have told, and I have six other examples here, one right after another.
What people would have told them coming up.
And Temple Grandin among them.
Probably the most famous autistic person there ever was.
She's professor of farming at, was it the University of Colorado?
Somewhere in the West.
Where because she sees the world the way animals do, she could advise farmers in ways they can handle and herd cows that does not create stress in them.
She figures stuff out.
She has research papers.
joe rogan
Yes.
neil degrasse tyson
But you're going to say, oh, she's not the life of the party.
Get her out of here.
What are we doing as human beings?
joe rogan
Can I give you an example, a personal example?
neil degrasse tyson
What the hell?
And so I was angry writing that chapter.
I was angry!
One more, I gotta go.
unidentified
Let me give you a personal example.
joe rogan
My jujitsu instructor, John-Jacques Machado, was born on his left hand.
He only has a thumb.
He has a genetic defect where he has no fingers on his left hand.
neil degrasse tyson
Call it a genetic feature.
joe rogan
A genetic feature.
neil degrasse tyson
See, you value judging.
joe rogan
It is a feature because he's a multiple-time world champion.
neil degrasse tyson
It is.
joe rogan
And because of the fact that he was born with this one hand that didn't have fingers, he developed a style of jiu-jitsu that enabled him.
You see his hand there?
neil degrasse tyson
Uh-huh.
joe rogan
And he's one of the absolute best that's ever done it.
And he developed a style of jiu-jitsu where he utilizes that left hand to get under chins because it's not encumbered by the mass of the fingers.
neil degrasse tyson
The other fingers aren't in the way.
joe rogan
Uh-huh.
And he slides it in there and sinks rear naked chokes on people.
And he also developed a style that didn't rely on grips.
He developed a style that's overhooks and underhooks, which became modern nogi jujitsu, which is incorporated in mixed martial arts because in mixed martial arts they don't wear the kimono.
neil degrasse tyson
And people who have fingers probably would have never even thought to think that way.
joe rogan
And people who saw Jean-Jacques Machado as a child said, oh, this poor child, he will never reach his full potential, and turned out to be one of the greatest ever.
neil degrasse tyson
Got one.
Here.
Um...
So, Oliver Sacks was a noted neurologist, pioneering entire subfields within his profession.
He was also a best-selling author, describing the human brain as the most incredible thing in the universe.
He led a remarkably varied life while suffering from a neurological affliction called prospopagnosia.
More commonly known as face blindness.
This condition contributed to his severe shyness since he couldn't recognize faces even if he recognized everything else about you.
At times, he would not even recognize his own face in the mirror.
joe rogan
Whoa.
neil degrasse tyson
And he's shy because if he's interested in a...
joe rogan
How does that work?
neil degrasse tyson
If he has a love interest...
If he has a love interest, he doesn't know the next time he sees that person whether that was who he had the conversation with.
Okay?
In 2012, after a lecture on hallucination at Cooper Union College in New York City, I asked him, if you could go back in time, would you take a magic pill in your youth to cure your neurological disorder?
Without hesitation.
He replied, no.
His entire professional interest in the human mind was inspired by the very disorders in his own brain.
He wouldn't have it any other way.
joe rogan
How does that work?
Where they can't see faces, but they can read?
neil degrasse tyson
No, they can see faces, they just don't recognize them.
It doesn't land in any place that you recognize.
Every face, even if you've seen it before, is like a brand new face.
joe rogan
Wow.
neil degrasse tyson
So he'd have to recognize your voice, your vocabulary, your accents, your body gestures, this sort of thing.
Wow.
joe rogan
So, doesn't Brad Pitt supposedly have that?
neil degrasse tyson
That I don't know.
I don't know Brad Pitt.
joe rogan
Doesn't he have...
neil degrasse tyson
...protspagnosia?
Yeah, I... Let's see if that's true.
joe rogan
I felt like he said he has some form of that.
neil degrasse tyson
Is that what he told one girlfriend when he saw the next one?
Is that what you're saying?
joe rogan
How dare you?
Yeah, he does?
neil degrasse tyson
He has some variant on that?
unidentified
What does it say?
jamie vernon
Yeah, he explained that.
unidentified
He hasn't officially been diagnosed with it.
jamie vernon
He has extreme difficulty recognizing people's faces.
joe rogan
Wow.
So maybe there's a varying spectrum of that disorder?
neil degrasse tyson
Yeah, of course, as it would be in anything.
joe rogan
Yeah, there it is.
neil degrasse tyson
Yeah, yeah.
joe rogan
Face blindness.
neil degrasse tyson
That's a very recent article there in this past year.
unidentified
Especially.
joe rogan
How crazy is he's got one of the best faces ever, and he can't recognize his faces.
neil degrasse tyson
Yeah.
Right?
So all of this you'd expect to happen on some kind of spectrum of severity, let's call it, or featurity.
And depending on where you are on that spectrum, you will have certain access to ways people have never thought before, ways people have never done things before.
Have you seen the video of the woman somewhere in East Asia who has no arms?
And she gets out of bed, folds up her, takes care of her child, puts on her makeup.
joe rogan
With her feet.
neil degrasse tyson
With her feet.
joe rogan
Yeah.
neil degrasse tyson
With her feet.
joe rogan
Yeah.
neil degrasse tyson
And so, yeah, she puts on her makeup and puts on her coat, puts on, there's a whole video about this.
And so, I don't know what else to tell you.
Oh, you must know this, my other guy here.
You must know him.
If not, get him on, okay?
Okay.
Get the dude on your show.
Hang on.
jamie vernon
Studies show one in fifty people may have developed that face blindness.
It could be genetic, but this doesn't...
joe rogan
Developmental.
unidentified
Hmm.
neil degrasse tyson
Yeah, there's...
It's...
joe rogan
Interesting.
But how is it that he always winds up with hot women?
Come on, Brad.
jamie vernon
He said people don't believe him because he's like, they think it's self-absorbedness and stuff.
joe rogan
Oh, that's interesting.
That's interesting.
neil degrasse tyson
Here's another one.
You ready?
joe rogan
Yes.
neil degrasse tyson
Matt Stutzman.
joe rogan
I recognize the name.
neil degrasse tyson
Is a championship archer.
joe rogan
Oh yes!
neil degrasse tyson
Who can outshoot most people who have ever wielded a bow and arrow.
joe rogan
He's actually coached by my friend John Dudley.
neil degrasse tyson
In competition.
joe rogan
Yeah.
neil degrasse tyson
By a bow and arrow in competition.
He's also a car enthusiast.
Oh!
He was born without arms.
He shoots his arrows and fixes his cars using his uncommonly nimble legs, feet, and toes.
Is Matt Stutzman disabled?
All I'm here to say is...
Because you started this conversation asking me, on the spectrum of...
Autism, where at some point in that spectrum, you focus like no one can focus before.
Possibly to the exclusion of personal hygiene and other concerns related to your health.
And civilization has definitely benefited.
From those who have been able to focus in such a way.
joe rogan
Yeah.
neil degrasse tyson
So maybe our species and civil, I'm just spitballing here, that our species and the advance of civilization itself has pivoted on the fact that in the variation of who, what and what we are, some of us can focus and solve a problem like what and what we are, some of us can focus and solve a problem like it was the most important thing we would Yeah.
And end up doing so, thereby pivoting civilization into some future that would have not otherwise been realizable.
So yeah, I'm all there.
joe rogan
Yeah, I mean the diversity of human beings and their interests and what they look like and their sizes and the way they interact with the world is one of the reasons why we can create such an amazing world.
neil degrasse tyson
But consider also, and it goes beyond just this, what we call these disabled features, right?
People with disabilities.
It goes to other things.
For example, you must know that it was not until 1987 where the American Psychiatric Association, with some names such as that, but the psychiatrists, Removed homosexuality as a mental disorder from their records, from their encyclopedia.
1987, a disorder.
And so, what does that even mean if whatever the number is, 10, 20% of people or higher are on a gender spectrum as measured in the multiple dimensions that have been revealed in recent years?
If you had control over the genome of your children 50 years ago, and if homosexuality has a genetic component, would you say, I don't want that?
That's abnormal, because you're going to go through that list of what is normal.
And you're going to say, I don't want any abnormalities in my children.
Not at all.
So there's an entire ethical frontier that is yet to be touched.
Yet to be resolved, I should say.
Certainly there are people thinking about it.
What kind of child are you going to create?
joe rogan
Well, this is the question.
When you have, and this is what I wanted to get to, when you have things like CRISPR and you have what could be legitimate genetic engineering of fetuses and of embryos.
neil degrasse tyson
You mean authentic?
It's authentic.
The legitimate implies it's sanctioned.
joe rogan
I mean, not sanctioned.
But the fact that that is an emerging technology and that, like all technologies, it will increase in its ability with innovation, with new versions.
Where do you think this goes?
Do you think it's inevitable that human beings engineer ourselves into these super creatures that are homogeneous?
neil degrasse tyson
Do you think I think we, as has almost always been the case, the science is advancing faster than our morality.
joe rogan
Yes.
neil degrasse tyson
Or our sensibilities.
joe rogan
Or appreciations of humanity.
neil degrasse tyson
You know, and often the scientific advance has very important plus sides to it.
Here's what I want to see happen.
If we can control the genome, Let's just start with what already exists in nature, all right?
We put ourselves at the top of the tree of life, but if newts could draw the tree of life, they put themselves at the top.
Why?
They can regenerate their limbs.
And we can't.
They would value that very highly.
So would we.
Let's get whatever that is in the newts.
Splice it into us.
Line up all the veterans who have, you know, missing limbs.
Put them first.
Regenerate those.
If lobsters can do it and crabs can do it and newts can do it.
joe rogan
They are doing research on that, correct?
neil degrasse tyson
I haven't checked it.
joe rogan
I believe I read.
neil degrasse tyson
I would hope so.
But we're doing research on...
Growing organs.
Yes.
There's a huge need for that.
joe rogan
Yes.
neil degrasse tyson
You don't have to wait for someone to die.
Right.
Particularly the day we have self-driving cars on the road dominating the population of cars.
I see that happening within decades, by the way, and I have good reason for thinking that.
But the day that happens, we lose.
So no longer do 35,000 people a year die.
joe rogan
Right.
neil degrasse tyson
In peak physical health, which has been a source of so many organs, organ donors, right?
You sign your card when you get your driver's license so that when you die in a car accident, we can harvest your organs.
You're young and all your organs work.
We don't harvest organs of 80-year-olds because they're 80 or 90, right?
Right.
The day we lose the 35,000 deaths per year, I hope that happens at a time when we can start growing artificial organs.
joe rogan
Have you done any playing around with auto-driving features on things like Teslas?
neil degrasse tyson
I know it's there, but I'm not mentally ready to experiment.
It's pretty amazing.
joe rogan
Jamie and I have the latest beta of Tesla self-driving.
Have you messed with it at all, Jamie?
Yeah.
neil degrasse tyson
Yeah, yeah, yeah.
joe rogan
What's your take on it?
neil degrasse tyson
I had someone drive me around with it in the beta.
unidentified
It's...
joe rogan
Not comfortable yet, is the best I would say.
You keep your hands on the wheel?
unidentified
Yeah, yeah, yeah.
joe rogan
Yeah, me too.
unidentified
Yeah, yeah.
jamie vernon
And I haven't had to take over, but there's like one time I was like, well, I'm not doing this right now.
unidentified
I'll test it another time.
neil degrasse tyson
Here's what I did do in a Tesla.
You put it on the...
Self-driving?
It's not self-driving.
unidentified
Auto?
neil degrasse tyson
No, just the simple...
What's it called?
All the old cars had it.
Cruise control?
Yeah, cruise control.
But it's managed cruise control.
So I put it at 50 miles an hour, the traffic slows to 30, it slows to 30 with a prescribed car distance in front of me.
The traffic goes to a standstill, the car stops.
The traffic picks up, the old cars wouldn't do that.
So it's doing this.
So I experiment with that.
And I noticed that when it starts from a stop, Or when it slows down, it's way harder on its brakes than I am.
joe rogan
Yes.
neil degrasse tyson
I'm way smoother driver than my cruise control.
joe rogan
Yeah.
neil degrasse tyson
And I've seen cars come in from the side, and it abruptly stops.
When I saw it before it did...
And so I don't know.
But we're at the beginning.
unidentified
Judgment.
neil degrasse tyson
It's dawn.
It's the dawn of this.
joe rogan
But you're recognizing patterns and judgment and whether or not someone's paying attention and whether or not it's going to be...
neil degrasse tyson
All that has to happen is that it goes into an AI learning mode and it gets the sum of all of these experiences of all drivers in these situations.
Yeah, AI is going to kill some people in self-driving mode.
But I guarantee you...
joe rogan
It's going to kill a lot less.
neil degrasse tyson
It will kill fewer people than in...
Then without it.
joe rogan
Have you seen Lex Friedman playing guitar while he's driving around in a self-driving car?
Yeah, Lex drove around in a Tesla while playing guitar.
neil degrasse tyson
Uh-huh, uh-huh.
joe rogan
It's pretty fascinating.
neil degrasse tyson
Right, so there's a headline here, and that I'm going to read to.
It's a very simple headline, but where is it here?
T-E... Oh my gosh, where is it?
joe rogan
There it is.
There's Lex.
neil degrasse tyson
Oh.
unidentified
That's pretty good.
Thank you.
joe rogan
Lex can shred.
Give me some of that.
You gotta listen to this.
Listen to this.
unidentified
Oh, yeah, he was playing along.
Here it goes.
That's good.
It's good stuff.
joe rogan
Listen to hear.
unidentified
Have you done Lex's podcast?
joe rogan
You would love him.
He's an AI researcher.
From MIT originally and now he's mostly doing independent work and doing his own podcast.
Brilliant, brilliant guy.
You would love him.
And he's got an amazing podcast too.
neil degrasse tyson
Okay, so here it's gonna be in this section.
joe rogan
I don't think you're interested in Lex's podcast.
Seems like he's not paying attention.
neil degrasse tyson
Hang on.
I got this.
No, thank you for the tip.
joe rogan
I'm trying to get him on, buddy.
neil degrasse tyson
I'm trying to get him in.
joe rogan
Lex actually is one of the most brilliant people I know.
I think you would love talking to him.
neil degrasse tyson
An interesting quote here from Walter Badshot.
One of the greatest pains to human nature is the pain of a new idea.
joe rogan
Really?
That guy's an idiot.
That's not the greatest pain.
Someone needs to kick him in the nuts.
It's human nature.
The pain of loss, the pain of failure.
There's a lot more pains.
neil degrasse tyson
The new ideas are amazing.
The longer quote I have here, just in all fairness to the fellow, is...
It is, as common people say, so upsetting.
It makes you think that, after all, your favorite notions may be wrong, your firmest beliefs ill-founded.
Naturally, therefore, common men hate a new idea and are...
Disposed, more or less, to ill-treat the original man who brings it.
joe rogan
Oh boy.
Now we're in the common man thing.
unidentified
Okay.
neil degrasse tyson
Alright, that's 19th century.
joe rogan
I like that even less.
neil degrasse tyson
Alright, here's a headline.
You ready?
And it's why our brain is not statistically prepared.
A headline.
joe rogan
Okay.
neil degrasse tyson
Tesla says autopilot makes its car safer.
Crash victims say it kills.
Both of those are true.
joe rogan
Yeah.
But less.
It's sort of like introducing mountain lions into areas to kill.
neil degrasse tyson
Correct.
joe rogan
Yeah.
neil degrasse tyson
Both of those are true.
And if you keep at it, yes, autopilot will kill...
AI self-driving will kill people, but that number will drop every single year.
And you know why?
Because every way that someone dies...
No other person will die that way again because they'll upload all the software and that does not happen.
This is what the airline industry did.
The FAA investigates every single crash.
You know why you can't take lithium ions onto a plane?
Because there was a UPS plane that had lithium ion batteries in the cargo and it caught fire.
And there's the audio of the pilots Talking to each other and to the thing while the plane is on fire just before the thing crashes.
joe rogan
Do you remember when they used to make you take the batteries out of Samsung phones when you got on planes?
neil degrasse tyson
I never used a Samsung phone.
joe rogan
Samsung phones had an issue.
One of their Galaxy Notes, they would burst into flames because they juiced up the battery capacity.
neil degrasse tyson
I remember it.
Yeah.
joe rogan
And they went a little too far.
Went a little crazy.
neil degrasse tyson
So all I'm saying is that...
joe rogan
They fixed that now.
neil degrasse tyson
Part of the diversity of who and what we are is who...
Who you love, what you want to look like, you know?
This resistance to the gender spectrum concerns me because it's a force of restriction on people's freedom.
And somewhere I read that America is like pursuit of happiness.
I read that somewhere, some document, right?
And so if someone Wants to dress in whatever way they want, and if it doesn't conform with your binarity, you're going to create a law to prevent them from doing it?
Are we any longer in a free country if you have that power over me to express my happiness?
And another thing we're not good at And I gotta go, like, soon.
How long we been talking here, dude?
joe rogan
Couple hours.
neil degrasse tyson
Damn.
Dude.
joe rogan
Come on, this is fun.
neil degrasse tyson
But I love you, man.
joe rogan
I love you, too.
neil degrasse tyson
I love you, man.
I love you.
joe rogan
I love you, too, man.
neil degrasse tyson
People don't know, we were outside wrestling a few moves.
I used to wrestle, you know?
joe rogan
I know you used to wrestle.
neil degrasse tyson
I was, like, captain of my high school team.
joe rogan
You started to have a little flashback.
unidentified
No!
neil degrasse tyson
It was the third period.
I was down four points.
Uh-oh.
joe rogan
The buzzer.
neil degrasse tyson
What was I saying?
joe rogan
We're talking about diversity.
neil degrasse tyson
Oh, yeah, yeah, yeah.
Another thing we're bad at.
We're bad at recognizing a spectrum of things when we confront it.
Our urge is to categorize it.
That urge is so great.
We categorize things that are fundamentally not categorizable.
For example, hurricane strengths.
Hurricane strength is a continuum of miles per hour of wind speed.
unidentified
But we cut it into five categories.
neil degrasse tyson
And you know what happens?
That affects us.
So Hurricane Irma goes from low Category 3 to high Category 3. They're just, oh, it's just Category 3, Irma.
It goes up one mile an hour?
It's breaking news.
Hurricane Irma strengthened to Category 4 just this past hour, and everybody crowds around the TV set.
So our brain doesn't allow a continuum.
We can't...
So what happens?
Are you a boy or are you a girl?
You have to be one of...
Maybe there's a continuum.
Okay?
Oh, you want to talk X chromosome, Y chromosome?
We can do that.
Fine.
All right.
So biogenetically, I can say that there's a boy and a girl or some variant on that, which is in the rare case where you have doubled up on the chromosomes.
unidentified
Intersex.
neil degrasse tyson
Yeah, intersex.
Sure, we can have that conversation, but that's not...
Visible to me in what you do when you wake up in the morning.
I don't see your chromosomes.
You know what I do?
I see what you do to make yourself look like a boy.
You go to the gym.
You'd have wimp muscles if you didn't work out.
Okay?
That's what you do because you're a boy.
You wear boy clothes so that everyone knows you're a boy.
If it was that obvious you were a boy, you wouldn't have to do all of that.
So, so much of what we do to split us into this binarity is artificially added on top of the chromosomes.
So, like I said, if you're a wimpy guy and you go wear man's clothes and you go to the gym because you want to look like a boy.
If you're a girl, you're a woman, and you have hair on your lip, can't have a mustache, you're a girl.
Got hair between your eyebrows, can't have that, gotta remove that.
Okay?
Your breasts are not large enough?
Get them enlarged.
As what happens to, what is the number?
300,000 breast augmentations a year in the United States?
Okay?
These are huge numbers to make us look more to fit into this binarity.
And suppose I don't buy into that binarity.
I say, I like the spectrum.
Someday I feel a little feminine.
Sometimes I feel, I'm not going to wear clothes that way.
You're going to come after me and say, I don't like that.
I'm going to pass a law.
Okay?
Oh my gosh, that's no longer a free country.
joe rogan
Is anybody saying that you should pass a law that men can't wear whatever they want or women can't wear whatever they want?
No one's really trying to do that.
neil degrasse tyson
There are forces of resistance in society that are strongly preventing it.
Really?
joe rogan
Well, I think that's unfortunate.
neil degrasse tyson
And by the way, some solutions, like which bathroom do you use?
There's solutions there.
Just make unisex bathrooms.
Every new restaurant in New York City is that.
So that takes an entire category of people's worries and concerns off the table.
joe rogan
When we're talking about genetic engineering...
neil degrasse tyson
By the way, that's in the chapter gender and identity.
And I didn't even get to color and race.
Oh my gosh.
Just before I go, I want to read a quick thing from that section, but go on.
joe rogan
Go ahead.
neil degrasse tyson
No, no, no.
Finish with your point.
joe rogan
Mike, my wonder is, if you try to look at what human beings are capable of doing now in terms of genetic engineering and what the hopes are, where do you think this leads us if this is allowed?
It's not whether or not it's going to be allowed.
It's going to happen.
Where do you think this leads us to?
When you look at the archetypal alien, What is it?
It's got a large head and no sex organs.
neil degrasse tyson
And they never have hair.
I want a hairy alien one day.
unidentified
A hairy alien.
neil degrasse tyson
With a hairdo.
unidentified
Right.
joe rogan
Yeah, right.
neil degrasse tyson
They're always bald, big eyes.
joe rogan
1970 afro.
neil degrasse tyson
Yeah, yeah.
joe rogan
What do you think that leads us to?
Do you think that leads us to one uniform shape?
Or do you think it leads us to everyone looking like Thor?
Where does that lead us to?
neil degrasse tyson
Yeah, but of course, Thor still had to go to the gym.
joe rogan
But what if there comes a point in time where that's not necessary?
neil degrasse tyson
Sorry, the actor who plays Thor still had to go to the gym.
joe rogan
Things like biostatin inhibitors, you aware of those?
neil degrasse tyson
Yeah, I am.
joe rogan
So if they incorporate that into the human genome, then you're going to have people that have incredible amounts of muscle mass, and they don't even have to do anything to achieve it.
neil degrasse tyson
But what you would have done was, as a parent or as someone in control, predetermine I agree with you.
joe rogan
And that people just start doing that to their children.
We're talking 100 years from now, 1,000 years from now?
neil degrasse tyson
Way sooner than that, 50 years easily.
joe rogan
Where does this go?
neil degrasse tyson
Easily 50 years.
Yeah, so you want to have the muscle-bound family?
But suppose one of them wanted to be a ballet dancer and had to be a little more lanky and elegant.
joe rogan
What if we get to a point where genetic engineering could be utilized on fully formed adults?
And you could change the shape of, like, you know, there's people that are transgender.
What if you could literally become a double X chromosome human being?
And you will literally have a vagina, literally have breasts, ovulate, have a womb.
neil degrasse tyson
I don't know how that would, I have to think about how that would happen.
That would be like an extreme limit of controlling your genomes.
Yeah, so that's a really interesting different world.
It means you can be whoever you want.
joe rogan
Right.
neil degrasse tyson
That's what we are on Halloween, right?
You're wherever you want to be.
joe rogan
What are your thoughts on human neural interfaces, like things like Neuralink and these technologies that are being proposed that would allow human beings to integrate with technology in a physical way, symbiotically?
neil degrasse tyson
Yeah, so I have a chapter in here called Exploration and Discovery, where we talk about the rapid pace of Technology and its impact on civilization, which is extraordinary.
But most predictions are wrong.
You get it right in the first few years and after a few decades.
joe rogan
But with new technology, new possibilities emerge that couldn't even be anticipated.
neil degrasse tyson
It comes in from the side.
joe rogan
Yeah.
neil degrasse tyson
Rather than...
joe rogan
Like the internet.
neil degrasse tyson
More of what...
Correct.
Correct.
It reminds me of there was an ad in 1992, 1903, early 90s from AT&T.
They had a relatively successful ad campaign where they said, have you ever wanted to say some futuristic thing?
And they say, you will.
AT&T will bring it to you.
joe rogan
Yeah, I've seen that.
neil degrasse tyson
One of the things, one of the commercials, was something I've never wanted to do, never dreamed of doing, never did, and never will do.
They show a guy on a beach, okay?
And he's working on a tablet, which was a good predictive thing.
Tablets did come.
He's looking at the tablet and said, and there's a surf coming in.
It's a beautiful beach scene.
He said, have you ever wanted to send a fax from the beach?
Well, you will.
AT&T. He's like, no, thank you.
No one has ever in the history of the universe wanted to do that.
joe rogan
But why wouldn't they if that was all that existed?
neil degrasse tyson
I'm just saying...
joe rogan
Well, now it's email.
It's the same thing.
neil degrasse tyson
No, it's email attachment, correct.
joe rogan
Sure.
neil degrasse tyson
But you don't see that coming if you're extolling the virtues of faxes.
unidentified
Right.
neil degrasse tyson
That's like in Back to the Future Part 2. A film made in 1989, we're riding high in faxes, the 89 to the early 90s.
Do you know what year that took place, was supposed to take place?
unidentified
Back to the Future 2. It's like modern.
neil degrasse tyson
Yeah, 2015. Yeah.
Okay?
So Marty pisses off his boss and he gets fired.
joe rogan
Yeah.
neil degrasse tyson
All right?
So the boss communicates this.
Via fax to his residence, okay?
Except this is the residence of the future.
He has three fax machines in his home.
So you see them come out on three different fax machines.
And no matter what room he was in, he would see it.
Because that's the home of the future.
Because a modern home in 1989 with one fax machine, many homes had no fax machines.
So this is how we're linear thinking people.
Here's Marty.
joe rogan
You're fired!
neil degrasse tyson
There, there.
Three different facts.
Four fax machines.
joe rogan
That's the future.
neil degrasse tyson
There it is.
joe rogan
That's what they thought.
Isn't that funny?
Oh no.
neil degrasse tyson
The future.
And so I talk about here how we also have linear brains, which prevents us from seeing exponential change.
And the best example of this is algae on a pond.
Okay?
So algae, you know, as it grows and it floats on the pond, you see like one square foot of it.
And you learn.
Someone tells you the algae is doubling every day.
And you have this huge pond, and you're told this, okay?
You go away for a month and come back, the pond is half covered with algae.
They say, oh my gosh, I was away for a month and this happened.
When will it be completely covered?
So what's the answer?
It took a month to get halfway.
So how much more time?
joe rogan
A week?
neil degrasse tyson
No, a day.
What did I say?
joe rogan
Doubles.
neil degrasse tyson
It doubles every day.
joe rogan
Yes.
neil degrasse tyson
That's how I started this conversation.
joe rogan
Yes.
neil degrasse tyson
See, the linear brain overrides even the stated facts.
joe rogan
And you know how they deal with that?
They introduce carp.
neil degrasse tyson
Oh, good.
I didn't know that.
joe rogan
And carp eat all the algae.
neil degrasse tyson
I didn't know that.
unidentified
Very good.
joe rogan
Yeah, but then the problem is they eat all the vegetation and you get like Lake Austin.
neil degrasse tyson
Oh, yeah.
joe rogan
There's almost no vegetation.
unidentified
It's a dead lake.
joe rogan
And all the bass have no place to hide.
neil degrasse tyson
Yeah.
Interesting.
joe rogan
Yeah.
Lake Austin looks like the bottom of a swimming pool now.
neil degrasse tyson
Interesting.
joe rogan
Yeah, it's a mistake.
neil degrasse tyson
Nothing there, too.
joe rogan
Whoops.
neil degrasse tyson
Yeah.
You think you know all the causes and effects of things, and then you don't.
joe rogan
Well, when I was on the Big Island, I found out about mongooses.
neil degrasse tyson
Big Island in Hawaii, yeah.
joe rogan
Yeah.
When I was there for the...
neil degrasse tyson
Can we call them mongoose?
Is that allowed?
joe rogan
They're so adorable.
We saw one at the resort, a mongoose.
Cute little fella.
neil degrasse tyson
Wait, but Hawaii has no snakes.
So what do the mongoose eat?
joe rogan
Unfortunately, they brought them in for rats, and they went after ground-nesting birds.
unidentified
Oh.
joe rogan
And so they've devastated local wildlife.
neil degrasse tyson
There it is.
When you're an island in the middle of the Pacific, that stuff is pretty tightly configured.
joe rogan
Those little fellas are so cute.
Okay, the mongooses found in Hawaii are native to India.
We were introduced to Hawaiian islands in 1883 by the sugar industry to control rats and sugar cane fields.
neil degrasse tyson
Any species in Hawaii is going to be invasive.
joe rogan
Yes.
But then it gets to a point where people are making the argument that wild pigs are no longer invasive because they've been there as long as the humans have.
neil degrasse tyson
Yeah, so it's only a problem when it's a problem, is really what that comes down to.
Right.
Right, right.
I'm told that LA palm trees are not native.
joe rogan
Right, they're not.
neil degrasse tyson
Yeah, but they did really well there, and they haven't overrun the city or anything.
joe rogan
Well, also, they're like symbolic of Los Angeles, the palm tree.
neil degrasse tyson
Yeah, you got it.
joe rogan
They're everywhere.
neil degrasse tyson
Okay, so I make a prediction by the year 250. I have a bunch of predictions here.
Okay, let's hear it.
And this is so that in 2050 you can say, Tyson, you had your head up your ass, okay?
I have no hesitation because I go through a whole set of predictions that all didn't come out right.
People predicting 30 years ahead.
And so I just want to join the susceptibility parade here.
joe rogan
Okay, maybe you'll nail a few.
neil degrasse tyson
Neuroscience and our understanding of the human mind will become so advanced that mental illness will be cured, leaving psychologists and psychiatrists without jobs.
In a shift that echoes the rapid conversion from horses to automobiles in the early 20th century, self-driving electric vehicles will fully replace all cars and trucks on the road.
If you want to be nostalgic with your fancy combustion engine sports car, you can drive on specially designed tracks akin to horse riding stables of today.
Very nostalgic.
The human space program will fully transition to a space industry supported not by tax dollars but by tourism and anything else people dream of doing in space.
We develop a perfect antiviral serum and cure cancer.
Medicines will tailor to your own DNA, leaving no adverse side effects.
And this is in response to your earlier question.
We will resist the urge to merge the circuitry of computers with the circuitry of our brains.
joe rogan
Have you ever seen the statistics?
neil degrasse tyson
I'm happy enough to just dig it up here.
No, I don't need to surgically implant this.
I'm seconds away from all the knowledge of the world that I could possibly want.
I don't have to surgically implant it.
I don't have that urge.
I'm sorry.
joe rogan
Right, but if they do increase the capacity for human knowledge and your access to information substantially to the point where someone with a neural interface has an enormous advantage over anybody who doesn't.
neil degrasse tyson
Well, they'll do it faster, perhaps, but I don't...
joe rogan
But not just faster, but change the way you interface with...
Information.
neil degrasse tyson
That remains to be seen.
And of course, a guy says that, Mr. Singularity.
joe rogan
Ray Kurzweil?
neil degrasse tyson
Ray Kurzweil, right.
He's a big fan of that.
Here's a new book where it's...
The singularity is nearer.
His first book was The Singularity Was Near.
joe rogan
What a prediction.
neil degrasse tyson
We will learn how to regrow lost limbs and failing organs, bringing us up to the level of other regenerating animals on Earth, like salamanders, starfish, and lobsters.
Instead of becoming our overlord and enslaving us all, artificial intelligence will be just another helpful feature of the tech infrastructures that serve our daily lives.
Those are my predictions to be found wrong in 30 years.
joe rogan
Do you have any fears of artificial general intelligence?
neil degrasse tyson
No.
joe rogan
Not at all?
neil degrasse tyson
I don't think that's where it's going to head.
Neither does Kurzweil, by the way.
I think we'll put intelligence in things that need to do things.
Get the perfect cup of coffee.
Put it in your car so it drives and doesn't get in an accident.
Put it in things.
To have the one thing that does it all, I don't...
joe rogan
I would love to hear you talk to Elon about this because he has a deep fear of it.
neil degrasse tyson
Yeah.
I'm anomalous there, so don't listen to me.
Listen to others.
joe rogan
You're anomalous in the fact that you're not concerned?
neil degrasse tyson
Yes.
If you go to AI experts, most of them are concerned that it poses an existential threat.
I think it'll just be more stuff that'll help us out.
joe rogan
But what about when it's used in military applications?
neil degrasse tyson
Well, that isn't ethical.
I mean, all military operations involve some ethical...
The ethical decision tree.
joe rogan
Right.
neil degrasse tyson
So it would be added to the ethical decision tree.
joe rogan
But when you have unethical foreign countries that will use these sort of artificial...
neil degrasse tyson
Well, that's tank, anti-tank warfare.
So you need ways to combat that.
Yeah.
It'll escalate.
Yeah.
unidentified
By the way, the countries have ministers of AI. We don't.
joe rogan
Yeah.
neil degrasse tyson
We're behind on that curve.
I'm worried.
Yeah.
joe rogan
That's the concern, right?
The concern is that someone else is going to implement it and they're not going to have ethics or morals behind it.
They're just going to have this idea of control and dominance.
neil degrasse tyson
Correct.
And so there's always the bad actor that you've got to – and the military, they're paid to consider the conduct of a bad actor.
joe rogan
And the real concern is that we become them to beat them.
That's the fear.
neil degrasse tyson
Yeah.
Except we're not autocratic.
We don't think we are.
So...
We would have to get an entire Congress, an entire electorate to vote that way.
joe rogan
Yeah.
neil degrasse tyson
And that's – if we do, I don't know what the future of the world will be at that point.
It's spooky.
joe rogan
It's spooky because, again, we don't have the ability to sort of extrapolate and look at the future in terms of like how all these things are implemented and what the overall result is going to be.
unidentified
Mm-hmm.
joe rogan
So you're not worried about these human neural interfaces at all?
No, I don't see it happening.
You don't see it happening at all?
neil degrasse tyson
No, I think we'll resist it.
I think it'll...
joe rogan
But didn't we...
There's a lot of people that resisted email.
Like, I don't even have email, man.
Those people all got on board.
neil degrasse tyson
A lot of people resisted cell phones.
People used to print their email, remember that?
And they'd print it and then read the printed email, remember?
joe rogan
Yeah.
But a lot of people resisted this idea of cell phones, but now they're everywhere.
neil degrasse tyson
No, the only resistance I'm referring about is the machine biology interface.
joe rogan
Right.
neil degrasse tyson
That's what we're going to resist.
We're not going to resist the continued advance of the technology.
joe rogan
But if it creates a superior human being.
neil degrasse tyson
It already has.
It beats us at chess, at Go, at any intellectual task we give it.
It's already superior.
joe rogan
If it's a symbiotic thing, if it becomes integrated with the human biology.
neil degrasse tyson
I think we'll resist that, that's all.
It's a prediction that we can...
unidentified
I think you will.
joe rogan
I'm going to hop on board right away.
I'm going to be one of the first people.
I'm going to drill a hole in my head, Elon.
Let's go.
neil degrasse tyson
Implant it.
joe rogan
I don't want to be left behind.
neil degrasse tyson
Okay.
joe rogan
Well, the real concern is that it's really going to separate the haves from the have-nots.
Because if it does give you an advantage economically, an advantage in terms of your intellectual capacity...
You're going to have this advantage because it's going to be prohibitively expensive, I would assume, initially.
neil degrasse tyson
Often things that are prohibitively expensive initially don't forever stay that way.
joe rogan
Right, like cell phones.
neil degrasse tyson
Of course.
joe rogan
But eventually it becomes...
neil degrasse tyson
Or flat panel TVs.
joe rogan
Sure.
neil degrasse tyson
They're like impulse items at Kmart.
joe rogan
I was just at Walmart.
neil degrasse tyson
I can't believe how cheap they are now.
It's nuts.
Yes, it's nuts.
joe rogan
Yeah.
neil degrasse tyson
It's crazy.
joe rogan
They were so expensive.
neil degrasse tyson
I remember.
And heavy.
joe rogan
Like 20 grand.
Yes!
neil degrasse tyson
Tens of thousands of dollars.
And they'd come in like wood crates.
joe rogan
Yep.
Yep.
neil degrasse tyson
And now you needed power tools to undo it.
joe rogan
You can do it yourself and mount them yourself on the wall.
neil degrasse tyson
Let me leave you with some thoughts here.
joe rogan
Okay.
neil degrasse tyson
Please do.
There's a section here on race and color.
Which is another thing with the variation of what we have in the world.
Just a point I want to make.
When European anthropologists started running through Africa and started describing what they saw, their urge was to say, Everyone in Africa is this thing, and they have dark skin, woolly hair, and that is a thing.
And they called it a race, and they called it the Negroes, okay?
And this is our attempt to classify into few categories something that might actually, in real life, be on a spectrum.
We know that the human species began in Africa.
And everybody who populates everywhere else in the world came out of Africa to do that.
What that tells you is that the genetic diversity within Africa as the origin of our species is greater than it is between any other two people anywhere else in the world.
But because the anthropologists were not thinking genetic diversity, they're thinking skin color.
They put them all in one bin.
But if you have the most genetic diversity, then in practically every way humans vary, you would find the extreme of that in the African continent.
Where would you find the tallest people in the world?
Watusi tribe of Africa.
How about the shortest people in the world?
joe rogan
Pygmies.
neil degrasse tyson
The pygmies.
Not even that far away.
Right.
Geographically.
They have the same skin color, so the Europeans said these are one group of people, one race.
Where might you find the slowest people in the world?
Well, no one looks for them.
Where would you find...
There's no races to find the slowest people.
How about the fastest people?
Africa.
People of African descent have dominated the long distance as well as the sprint.
Two completely different physical abilities.
Oh, but they're all dark-skinned people.
They're all Negroes.
Where would you likely find the dumbest person in the world?
Africa.
How about the smartest person in the world?
Africa.
joe rogan
How about the Egyptians?
neil degrasse tyson
The Europeans did not look for people smarter than they were.
And to this day, where they find evidence where that might have been the case, you have people saying aliens did it.
Egypt is, of course, in Africa.
A brilliant civilization.
Oh, my gosh.
While Europeans were still either disemboweling heretics or whatever the hell they were doing, Even before that, thousands of years ago.
So my point is, if you don't look for it, and you don't find it, and you're going to create a map of humans of the world, you're going to put yourself at the top.
That's what you're going to do.
And you're going to write things like this.
Who do you want to hear from?
Thomas Jefferson or Francis Galton?
joe rogan
Jefferson.
neil degrasse tyson
Jefferson.
1785, speaking of the Negroes, comparing them by their faculties of memory, reason, and imagination, it appears to me that in memory, they are equal to the whites, in reason, much inferior, as I think one could scarcely be found capable of tracing and comprehending the investigations of Euclid.
And in imagination, they are dull, tasteless, and anomalous.
joe rogan
What is Euclid?
neil degrasse tyson
I honestly don't know how many Euclid-fluent white people Jefferson knew in the original American colonies.
Euclid invented geometry.
Euclidean geometry is ancient Greece.
And his books still exist to this day.
So he's saying, the black slaves don't know Euclid, can't figure out Euclid.
joe rogan
Well, they haven't been educated.
neil degrasse tyson
Regardless, how many white farmers in 1785 USA knew Euclid?
Zero.
unidentified
Okay.
neil degrasse tyson
But whatever were his observations and objections to black people, he had no hesitation continually mating with at least one of them, producing six children.
So you know what I did here?
Oh, then there's a guy who wrote a whole book comparing black people and white people, a book that was used into the 1960s.
It was called The Origin of Races by Carlton Kuhn.
He wrote, if Africa was the cradle of mankind, which he recognizes, it was only an indifferent kindergarten.
Europe and Asia were our principal schools.
So these are people putting themselves at the top.
He's white, so he's got to put white people at the top.
Then I thought, suppose anthropologists We're black racists instead of white racists.
What would they write?
What would they come up with?
joe rogan
Well, also what he's saying is ridiculous because if it's kindergarten, how did they do the pyramids?
It's the most complex structures ever known to man.
neil degrasse tyson
Hold on.
joe rogan
We can't reproduce today.
All of us.
neil degrasse tyson
My only point is...
When you have that mindset, and you have to put yourself at the top, and all people with dark skin are one entity, you're not looking for people smarter than you.
There's other evidence here.
Do you realize that the people who get the highest scores on standardized tests in England are immigrants from the Igbo tribe in Nigeria?
And their kids outscore all the, quote, native white people in the town.
If you're not looking for them, you're not finding them.
It just doesn't...
It's a thing.
It's all here in this chapter.
And all I'm doing is bringing science to it.
That's all I'm doing here.
And...
Where is it here?
Okay.
unidentified
So...
neil degrasse tyson
Black...
Yeah.
Here it goes.
Then I gotta go.
I can't keep staying here, dude.
joe rogan
It's okay.
You can come back.
There's a lot of little stickies on that book.
I'm sure you have many other things to talk about.
What is the book, by the way?
neil degrasse tyson
Oh.
Starry Messenger.
joe rogan
Is it available now?
neil degrasse tyson
Cosmic Perspectives on Civilization.
joe rogan
Is it out currently?
neil degrasse tyson
It came out eight weeks ago.
joe rogan
Please tell me you did the audio version of it.
neil degrasse tyson
I did.
joe rogan
Thank you.
neil degrasse tyson
I did.
joe rogan
I hate when people have other people do the audio version.
Oh yeah.
neil degrasse tyson
I did the audio version.
unidentified
I'm glad.
neil degrasse tyson
Oh yeah.
joe rogan
Of course you.
You'd have to.
neil degrasse tyson
I could not do the audio version of this.
joe rogan
Some fucking actor?
neil degrasse tyson
I talk about the pyramids here.
Even Elon Musk, by the way, tweeted, pyramids...
Aliens built the pyramids, obviously.
Elon said that?
joe rogan
I think he was joking around.
neil degrasse tyson
Possibly, but he said it, and it's in a...
joe rogan
You know, Elon likes to joke around about shit.
neil degrasse tyson
Here's one.
On May 1st, 2021, a talented chess player reached the title of National Master for having achieved a U.S. Chess Federation rating above 2200, landing among the top 4% of 350,000 rated players in the world.
A rating achieved that was 500 points higher than that of his chess coach.
Just a few years after learning how to play the game.
That prodigy is a 10-year-old boy named Tani Tolua Adewumi, the son of Nigerian refugees to the USA in 2017.
His family spent a brief time living in homeless shelters in New York City before his parents established stable employment and permanent residence.
I played a brief chess game against the little fellow in March 2021 on Grandmaster Maurice Ashley's Twitch platform.
A live streaming social media interface.
The game was indeed brief.
Yeah, he wiped.
wipe the floor with me.
Speaking of Nigerians, immigrants to the U.S. enjoy an 8% higher household income than the national average.
Nigerian immigrants to the United States.
And ethnic Nigerian children in the United Kingdom, especially those from the Igbo tribe, consistently attain higher test scores on average than their white children.
unidentified
What is it about Nigeria?
neil degrasse tyson
Occasions to pause and wonder what depths of intellect...
These are occasions to pause what depths of intellectual capital in math, science, and engineering or any field lay hidden deep within the African continent or anywhere else on earth, lost for now or lost forever for want of an opportunity to flourish.
I'm going to leave you with a fast list.
I want to tell you what my racist black anthropologist found.
Let's go back to the 19th century and let all anthropologists be black racists instead of white racists.
Okay?
joe rogan
Okay.
neil degrasse tyson
What would they say?
So, all right.
Chimpanzees are humans' closest genetic relative.
We just need to find similarities between chimps and white people, and that would be surefire evidence of their less evolved state.
Because that's what people were saying.
The blacks were still evolving, and they show a chimp, a black person, and a white person.
And so you can enslave black people and laws against them.
It's a way to justify it, because of course you're going to put yourself at the top.
So now, hypothetical black racist anthropologist.
Chimps and other apes.
So this is a list.
This is in a book that was never written.
Chimps and other apes grow hair all over their bodies.
The hairiest people you've ever seen have been white people, with mats of hair across their chests and ascending their backs.
Their body hair can even reach upward and out of their shirt collar.
Black people do not remotely approximate this level of hairiness.
There was no mention of this in any of those books.
Distinct from their face, hands, and feet, part the hair of most chimpanzees the way they do to each other when checking for lice, and their skin color is white, not any shade of black or brown.
Chimps tend to have big ears relative to their head size.
After decades of ear-watching, I can attest that the biggest ears I've ever seen on humans have been on white people.
Have a look yourself, next time you're in a crowded public place.
Doubtless there's strong overlap, but the size of black people's ears can be as little as half the size of white people's ears.
You might now ask about the famously large ears of President Barack Obama.
But he is precisely half white.
Just as much white as black.
So maybe his big ears come from the white half of his family.
For most of the 20th century, Neanderthals were portrayed as stupid and brutish.
Turns out, beginning in the 1990s, genetic research revealed that Europeans are between 1 and 3% Neanderthal.
Africans, zero percent.
That can't be good for Europeans.
Time to clean up that backward primitive image.
Since then, published references to Neanderthals instead comment on what must have been their creative, artistic, inventive, and articulate ways crafting sophisticated tools and technologies to shape their world.
Look how easy it is to be racist.
Let's continue.
Chimpanzees invest quality family time pruning each other's hair.
We've all watched them do this.
Apparently, the lice they find must be tasty, because whoever plucks them from the other chimps' head also eats them.
Ever hear of a lice outbreak among black children?
Probably not.
White children are 30 times more susceptible to lice infestation than are black children.
The parasite simply likes to lay eggs in the hair of chimpanzees and white people more than on the hair of black people.
This goes on.
This could have been included and they would have said, well, wait a minute, maybe all humans are together and chimps are something completely different.
But they didn't go there.
Their bias prevented their analysis of information that stares flat into their face.
Okay?
Here's one.
I'm going to skip some here because I got to go.
I got a plane waiting for me.
I'm skipping some here.
Ready?
joe rogan
Yeah.
neil degrasse tyson
This is one more from the Chimp Vault.
I have others that are not chimp related.
Here's one.
Chimpanzees love to swing in trees.
Apparently, so do suburban white children.
They typically can't wait to build and live in a backyard treehouse.
You have not likely seen black children even contemplate the idea.
White people clearly want to return to their fully primitive state.
This would be a racist black person, okay, from the 19th century, publishing, trying to find ways to enslave white people.
That's a cosmic perspective.
That's a, look, dude, this is what we were doing as humans to each other.
Not recognizing authentic diversity in who and what we are.
Trying to separate, to say, I'm better, I make the rules, and whatever rule I'm making, I'm going to put myself at the top.
And you're not going to be at the top, because you're different.
joe rogan
Do you anticipate that as people get more education, more information, and as we evolve, that we'll stop doing that and we'll start recognizing the importance of diversity?
neil degrasse tyson
I want to believe that.
joe rogan
And that it's our strength?
neil degrasse tyson
I want to believe that.
joe rogan
I want to believe that, too.
neil degrasse tyson
I so want to believe that.
Okay.
Here it is.
Then I really gotta go.
joe rogan
Okay.
Last one.
neil degrasse tyson
This is a quote, a short quote from Horace Mann 200 years ago.
I want this on my tombstone.
I beseech you.
Nobody uses beseech anymore.
I love it.
I beseech you to treasure up in your hearts these my parting words.
Be ashamed to die until you have won some victory for humanity.
Our primal urge to keep looking up is surely greater than our primal urge to keep killing one another.
If so, then human curiosity and wonder, the twin chariots of cosmic discovery, will ensure that starry messages—these are messages from science, from the sky, from the universe—continue to arrive.
These insights compel us, for our short time on Earth, to become better shepherds of our own civilization.
Yes, life is better than death.
Life is also better than having never been born.
But each of us is alive against stupendous odds.
We won the lottery only once.
We get to invoke our faculties of reason to figure out how the world works.
But we also get to smell the flowers.
We get to bask in divine sunsets and sunrises.
And gaze deeply into the night sky they cradle.
We get to live and ultimately die in this glorious universe.
joe rogan
That's a hell of a tombstone.
neil degrasse tyson
Dude, I gotta run.
joe rogan
Thank you, sir.
neil degrasse tyson
One day I'll come back and just chill.
We'll lift weights together.
joe rogan
Okay.
neil degrasse tyson
Wrestle a few rounds.
joe rogan
Let's do it.
neil degrasse tyson
You know.
joe rogan
Thank you very much.
unidentified
Love it here.
Appreciate you.
neil degrasse tyson
Thanks for having me.
joe rogan
Thank you.
