Speaker Time Text
joe rogan
Oh, wait a minute.
Are we going live?
Boom.
And we're live.
Mr. Carroll, how are you, sir?
sean carroll
Very good to be back.
joe rogan
Very good to have you back.
So you have a podcast now.
sean carroll
I do.
I've joined the ranks.
You inspired me.
joe rogan
Well, it's important.
We need people like you out there.
You have, what, seven episodes so far?
sean carroll
Seven episodes up.
A few more in the can.
I'm going to try to dribble them out once a week for the first six months or so, see how it goes.
joe rogan
Are you enjoying the process?
sean carroll
I am.
Mindscape, by the way, is the name for those out there in podcast land.
Yeah, I'm loving it.
The thing that tilted me over toward doing it, because look, I have a day job, right?
I can't spend too much time doing this stuff.
But what I realized, it was an excuse, a license to talk to people who are not just physicists, right?
Because I have intellectual interests that go way beyond just what I do for a living, and in academia, you're not allowed to take seriously anything other than your Your discipline, your job, right?
I'm allowed to be talking about physics but nothing else.
So now I can talk to historians and economists and philosophers and psychologists and it's great.
joe rogan
Well, you could have just gone to Evergreen State and then you could talk about anything.
When you're teaching a professor, you could just – if you're a professor, you could teach them dance.
sean carroll
We have to break out of the system.
We have to do it ourselves.
joe rogan
Yeah, man.
Gotta break out of that system.
So your podcast, you decided that this would be a great venue for you to just expand on subjects and just get into anything that you'd like.
sean carroll
Well, you know, I have opinions about things and I've never been one who said you shouldn't talk about things unless you're a PhD credentialed expert, right?
I think everyone should be talking about everything, but you should know what your level of expertise is.
So if you're not an expert, you should listen to people and you should then make your own decisions, but you should first gather the information.
And so I don't feel quite like I can go – I have a blog, whatever I want on my blog, but I can't really – I can expound on my theories of economics because what do I know about economics?
But I can call up a very expert economist and chat with them on the podcast and both I will learn something and hopefully the listeners will.
joe rogan
So you're going to just basically talk about anything.
sean carroll
The shtick is we sort of try to pick an idea, right?
So for the hour or whatever it is, I don't have your stamina.
I can't do the two-and-a-half-hour thing.
I know.
I need more nitrous caffeine in me.
But yeah, for an hour, hour and a half, I'll get someone who's an expert and we'll dig into an idea and try to understand what's going on in sort of everyday people's language and how it fits into the bigger picture and things like that.
Trying to mix up, you know, good old professors, which are my peer group, to sort of – I got some people coming out of left field.
I had a professional poker player.
I have a movie director coming up, a chef and things like that.
So – but basically, yeah, whatever I want to talk about.
joe rogan
That's awesome.
So is this for your own edification or are you just using it as just a platform?
sean carroll
Like what – Yeah, I think that my – like philosophically, I treat it like it's for me, right?
Like I'm not going to do guests or topics or not do topics because the people say so, right?
There's plenty of people out there who don't want me to talk about anything other than physics, right?
Or at least nothing that involves politics or religion.
joe rogan
Stay in your lane, bro.
sean carroll
Very much, right.
But I love talking about politics and religion.
So guess what?
I'm going to talk about those things.
And so – and then hopefully it finds an audience, right?
And so I'm willing to listen to suggestions but mostly I have to treat it like it's for me.
joe rogan
Trevor Burrus Well, I think it's absurd to ask someone to not talk about things if they're interested in those things.
sean carroll
Aaron Ross Powell People love doing it, right?
Like I especially love the commenters saying, oh, of course he's a scientist so he knows nothing about politics.
I'm like, you're an anonymous YouTube commenter.
Why should I listen to your opinions about politics?
joe rogan
You definitely can't listen to the opinions of anybody that's willing to take the time to comment on YouTube.
That's a problem.
I had a whole bit about it, because I was like, what kind of a person does that?
Who listens to a video and goes, well, it's about time that I put in my input?
It takes a very rare breed, unless they have a real specific expertise in what's being discussed.
Maybe it's about auto repair, and that is not how you replace a transmission.
Here's why.
sean carroll
Or if you're just asking questions.
Like I love my comments.
Like mostly the comments even on my YouTube.
Like so I send the video.
I don't do video, right?
I'm just doing audio podcasts.
But you can put them on YouTube with a static image.
And for some reason people like that.
People listen to podcasts on YouTube, right?
joe rogan
A lot of them.
sean carroll
Yeah.
And the comments have actually overall been surprisingly good because YouTube is one of the worst, right, overall.
unidentified
Right.
sean carroll
But, you know, people say, like, oh, I didn't know that, or tell me more about this, or this was interesting.
That's great.
Like, by all means, do it.
But if you're like, don't talk about that, I want to hear about this, then, you know, block, go away.
joe rogan
It only takes a tiny drop of LSD to pollute a whole bucket of water.
sean carroll
There you go.
joe rogan
And that's really what the deal is with YouTube comments.
It's just that the sheer number of people, the problem is that YouTube has a dedicated I don't know why, but that platform seems to attract some of the worst in people that comment.
sean carroll
And I'm, you know, I cannot claim that I'm immune to reading it and getting annoyed, right?
I'm like, you idiot.
I know I should just say, forget it, move on with my life.
I'm like, damn it.
joe rogan
Well, it's interesting in a lot of ways.
I mean, there's something fascinating about this new form of communication where someone can send this very just flat text.
You don't know anything about the background of the person that's sending it.
And there's a style of doing that that's designed to kind of mess with your head.
sean carroll
Just like poking all of your nerves, right?
Yeah.
And look, let me just – just to redress the balance here.
It's great that we have these new ways of talking to each other, right?
And part of – I glancingly mentioned the fact that academia wants you to stay in your lane very, very much.
And I think that that's a shame.
And so I think that part of the many hidden purposes of my podcast, one of them is to – Dissolve the boundary between science and the rest of our intellectual life, right?
Like sometimes I'll be talking about science, sometimes I won't.
Like we tend to silo off science as a thing and then like economics and history and political science is another thing that is out there and relevant to the world and science is something that is sort of a form of entertainment for a lot of people.
And I want to mix it all up.
I want the different people talking to each other.
And so overall, by all means, comment on the YouTube videos and keep that conversation going.
joe rogan
That's good of you.
That's a very healthy attitude.
And that's kind of the attitude that you have to have if you're putting everything out there.
sean carroll
Yeah.
And just one more irony is like I'm not – I don't seek conflict.
I'm a conflict-averse person.
Like I just want – I don't want to argue with people.
But I do want to say things that are true and not everyone agrees about what is true.
So there's going to be arguments.
So I put up with that but I'm not seeking it out.
So I would like this utopia of rational discourse where everyone is talking about ideas in a dispassionate way and in good faith looking toward – moving toward the truth.
joe rogan
It would be nice if we had like a system, like almost like a rating system for humans, like a Yelp for commentators.
sean carroll
People are trying that.
joe rogan
It's not a bad idea.
It really isn't in terms of like people review your comments on things and enough people decide like this is just unnecessary.
sean carroll
Yelp for expertise.
joe rogan
Yeah.
sean carroll
Or for commentary in general.
joe rogan
Well, all the above.
Yeah, I mean, I think we're probably going to move to some sort of a system like that.
In fact, some people are actually advocating that for society to have some sort of a rating system for people and almost a new kind of currency, like a social currency.
sean carroll
They're doing it in China, right?
joe rogan
You heard this?
Yes, yes.
It's scary for people, though, because it's China.
And, you know, China is a trippy place, and it's very trippy in terms of it's sort of got capitalism going, but it's also a communist dictatorship, and it's controlled by the government, and all the companies are also in...
You know the thing with Huawei?
Am I saying it right?
People are getting mad at me about that.
Huawei?
I think it's Huawei.
It's now the number two cell phone manufacturer in the world, and they're forbidden to work with US carriers.
The United States government does not trust this company, so they've said, you know, this company has apparently done Some shading things according to them, not according to certain tech people who say it's nonsense.
So now they're keeping them from selling their cell phones with AT&T and T-Mobile and whatever.
But they're the number two manufacturer in the world now.
They just surpassed Apple.
sean carroll
Because China's just so big.
joe rogan
China's a trip.
sean carroll
Yeah.
Well, it's...
They know very well.
It's kind of remarkable to me that China has been so stable and successful because there are people who don't like it.
There are people who rebel against the system but they've been so – the government has been so enormously successful at controlling information, controlling what you learn.
Like you can't Google Tiananmen Square if you're there in China.
You can't get those images or anything like that.
Companies want to do business there, so they'll go along with it.
And I'm not sure if it's stable.
I talked about this in my last podcast with Yasha Monk.
I'm not sure that democracy is stable either.
So when the technological capabilities are changing so rapidly, huge abuses and huge changes are on the horizon even if we don't know what they're going to be.
I mean that's – That's my worry about the social credit system, right?
Like it's so obviously abusable, right?
Make the wrong people have bad credit, make the people you like have – I mean if this is run by the government, you're going to trust them to do it fairly?
I'm a little skeptical about that.
joe rogan
Well, I think this last election and the subsequent analysis of the manipulation of the election has been very eye-opening to people.
The Russian troll farms.
Have you been paying attention to any of that stuff?
That is a stunning revelation that there's 24-7 businesses where people are set up, where they're hired to just...
Tweet and post things and comment on things and they're all working in some way to try to manipulate the way people look at the news.
sean carroll
Yeah, and the most interesting thing to me, I thought like if they were clever, they will do this and they do it.
It's not just that they have… A policy that they want to push, right?
Or a candidate they want to push.
They want to foment disagreement, right?
They will take the most radical views on either side and pump them up just so Americans are tearing at each other's throats.
And yeah, that kind of works, right?
That's pretty successful so far.
joe rogan
There was a Radiolab podcast where these people that were Trump supporters detailed being contacted By these Russian troll farms, where they organized these rallies, and they organized these protests, and they even hired a fake Hillary.
They hired a fake Trump, and they're going to have the Hillary in a cage, and they wanted everybody to yell out, lock her up.
These Russians coordinated this whole thing.
sean carroll
Right.
And then once it starts, it organically takes over, right?
I mean you probably saw just the other day this Trump rally where the CNN reporter was trying to do … Jim Acosta.
Yeah, trying to do a camera spot and he just like got drowned out by people shouting at him and shouting obscenities.
Yeah.
I don't know what – that's bad, right?
OK. I mean it's bad.
The media, I wouldn't want that to happen to Fox News.
I wouldn't want that to happen to people I disagree with.
You got to let the people in the media be the media.
They're not the enemy of the people.
joe rogan
Well, what he's done is very dangerous.
It's very sneaky and very dangerous, and it's very manipulative, and he's essentially in survival mode.
And when people are in survival mode, he's not thinking at all about the importance of the press.
He's thinking about his situation, his stance, his position in life.
Preserve that.
And what's the best way to preserve that?
Well, someone's attacking me, attack the people who are attacking me.
sean carroll
Yeah, you build yourself up by creating an enemy that everyone can agree on, right?
One of the chilling things that Yasha pointed out, there's really – despite the rhetoric, there's never been a successful truly multi-ethnic democracy in the history of the world.
Like democracies that have worked have worked because one group is the boss, right?
And they give rights to the rest of the people and so forth and try to be fair to some extent.
But – That's changing.
As the demographics of the world are changing, we're becoming more of the patchwork that we claimed to be years ago, and people aren't quite happy with that.
They're not comfortable with it, and this is something that can be used to gin up emotional reactions.
joe rogan
Yeah.
There's – people are terrified of change too.
There's always this nostalgia for the past.
sean carroll
Yeah.
And a past that is not necessarily accurate.
unidentified
Right.
sean carroll
It has that they envision.
And it's – and I'm sympathetic with the real problems, right?
There are real problems with inequality and With healthcare and with jobs and not just the number of jobs, but the jobs are changing.
Not everyone is really tooled up to be a high-tech office worker in this day and age.
And so I take those concerns really, really seriously.
But those concerns are being channeled in very unproductive ways to scapegoat people who don't deserve it.
joe rogan
One of the things that's fascinating to me that seems to be boiling under the surface is the possibility that we might need some sort of universal basic income to deal with what's happening with AI and automation.
Like automation of cars, automation of normal jobs, food preparation, things that people have come to just take for granted that a human's going to be doing that.
It's entirely possible that millions and millions and millions of people are going to be out of work within a very short period of time.
And it seems to me that it's one of those really sneaky things that might just catch us before we're ready for it.
sean carroll
Yeah, I think that if you extrapolate very far ahead into the future and imagine what utopia is supposed to look like or the far technologically advanced civilization, why wouldn't we imagine that work is done by robots and machines and human beings are free to be creative or artistic or athletic or just sit on their butts why wouldn't we imagine that work is done by robots and machines and human beings are free
If you believe that that's a possible future, then the way to get there is to, as robots and machines do more and more, make it more and more possible for people to live without working.
I think that's at least – I have no idea whether it works in practice.
I'm not an economist.
I haven't studied it.
But I think it should be taken seriously as an idea.
joe rogan
If you looked at it as a pessimist, if you looked at it with a cynical perspective, you'd say, well, people just – they don't have motivation.
Then they behave like rich kids or entitled people or people who won the lottery.
They blow all the money.
They don't take it seriously because they didn't earn it.
It goes against human nature.
sean carroll
Yep.
I get that and maybe it does.
Let them do it.
Who am I to tell people that they need to be virtuous by earning a living in some job that they may or may not be able to keep for very long?
Yeah.
People who say that usually haven't gotten fired from their jobs recently, right?
joe rogan
Right, right.
Yeah, and I always feel like the people that are actually ambitious...
But the real problem, I think, would be growing up with that.
I think if you got it as an adult, you'd probably recognize it as a safety net that it is.
But if it was during your developmental process, you might rely on it as a constant, and so that might be a problem in terms of motivation.
sean carroll
I think so and I think that – and you see it, right?
I mean I have friends at various levels of income and class that they grew up in and you can always tell people who grew up in very comfortable environments because they don't have jobs.
They have projects.
Like I'm working on a project because they're not really worried about the project failing.
Like if you grew up without that safety net, you're more cautious, right?
Like you have to have a failsafe.
You have to have a backup plan.
But what if everyone had that backup plan?
What if we could all do projects instead of work?
Is that really a worse world?
joe rogan
I don't know.
Do you know any trust fund people?
sean carroll
Oh, yeah.
joe rogan
Yeah, the ones that I know all blow their money.
sean carroll
Actually, I know some very wealthy people who raise their kids really well.
joe rogan
As trust fund people.
sean carroll
Oh, yeah, as people who never need to work a day in their lives, and they all work really hard.
joe rogan
That's so weird.
sean carroll
Yeah, it's possible.
joe rogan
Find those people and clone them.
sean carroll
Yeah.
joe rogan
Find out what made them tick.
So they found a passion.
They found something that they're actually...
That seems to be a giant issue.
sean carroll
That's right.
And your parents need to sort of encourage that.
Parents matter when it comes to like if you are very wealthy, do you feel like you deserve it or do you feel like, oh, I should give something back because I'm really, really fortunate, right?
joe rogan
Well, there's cockamamie ideas that come from people that haven't earned their money, too.
One guy came to me with this crazy idea for this project he's doing and wanted me to get involved in it, and I was going over the details of it.
I was like, I don't think this is going to work.
Why is this guy so enthusiastic about it?
And then the more I dug into it, I'm like, oh, he got all this money from his dad.
Right.
unidentified
Oh.
joe rogan
Well, there you go.
james damore
This guy's just—he's got pipe dreams.
sean carroll
Yeah.
I mean, I guess I feel, just to be honest about it, like, I'm very lucky.
Not because I grew up wealthy, because I didn't, but because I now have a job that represents what I want to do.
Like, what I would do with my life— If I were independently wealthy, isn't that different from what I'm doing right now, right?
That's bliss.
Exactly.
But therefore, I kind of think that I would like a world where everyone can do that, if that's what they wanted.
joe rogan
That would be amazing.
sean carroll
Yeah.
joe rogan
The real question is, does everybody have an actual interest?
And if they don't, is it nurture or nature?
sean carroll
And if they don't, do we force them to?
Is that what we want to do?
joe rogan
I don't want to do that.
Find a thing.
sean carroll
You know, and actually I never tell people like follow your passion or find what you love because look, there's a lot of people who need to earn a living, right?
There's a lot of people who just need to do work because they need to pay the bills.
That's fine.
That should be respected.
In the world we have right now, that's an honorable thing to do and not everyone gets to just do what they love.
joe rogan
That's true.
There are some things, though, that you can do for a living that you'll actually enjoy.
Like, you need to make a living, but because of your temperament, because of your interests, you can find a thing, whether it's carpentry or whatever it is that you find to be fascinating and fulfilling when you're actually doing it.
You're making a living, but you're also doing something that, man, this is very satisfying.
sean carroll
Maybe.
Maybe that's true.
I mean, it's certainly true.
It can be done.
Can it be done for everyone in the world?
I don't know.
joe rogan
That's a good question.
unidentified
I don't know.
joe rogan
Yeah.
Well, there's so many styles of living, too.
You know, when you're talking about China, I was in China recently.
We spent some time in Thailand, and we flew through China.
And one of the things you realize about China is there's a totally different way of moving.
Like, people just walk right through people.
I mean, there are lines.
If there's a space in a line, they don't respect that space.
They go right into that space, right in front of you.
Like, oh, there's a space there.
They didn't even think of it as rude.
It's not rude.
sean carroll
It's just the style, right.
joe rogan
Yeah.
It's just how it is.
sean carroll
We went through Southeast Asia for a few weeks and visited Vietnam and Thailand.
And they're right next to each other, but just the behavior in the city is utterly different.
Like, just walking down the street.
It's just a different culture.
joe rogan
I haven't been to Vietnam.
What was that like?
sean carroll
Oh, Vietnam was my favorite.
It was the best.
joe rogan
Everybody says that.
sean carroll
It's great.
I mean, I don't know.
I was there for a few days, right?
I'm sure that there's depths to the country that I didn't perceive, but it was coming to life.
Literally, the week we were there was the first McDonald's was opening in Vietnam, which is not good, but at least it meant we were there in a pre-McDonald's society, right?
Physically very beautiful.
The food was amazing.
It was all scattered out like the – people just go crazy on the streets in any direction they want and it was not organized or anything like that.
But it was very genuine.
It was – people were trying to be nice.
People seemed to be very friendly.
We didn't speak any of the language or anything like that.
And it was just a wonderful experience overall, yeah.
joe rogan
That's awesome.
Yeah.
Asia is a trip.
It's a really different part of the world.
sean carroll
China is – yeah, I've been to China too and it's a – that's a trip for a different reason, right?
And I'm scared by China in the sense that I'm worried that they will succeed while still being repressive dictatorship, right?
Like I remember reading these memoirs from Bertrand Russell when he visited China.
And he was rhapsodizing about this is an amazing culture, amazing people.
This is great.
And I'm like, does he not know it's a communist dictatorship?
And then my brain kicked in.
I'm like, oh, no, it was 1912. It was not a communist dictatorship at the time.
And there's a great tragedy in the way that China has been sort of repressed for so long.
I think there's an immense – There's potential and promise there but it's also the possibility that they just remain this autocracy forever and some people's lives improve and a lot of people's just drudgery for billions of people.
joe rogan
Trevor Burrus Yeah, it's totally possible.
It's fascinating that they become this combination of things, a combination of both capitalism and communism.
sean carroll
Trevor Burrus Yeah.
Well, I think that's it.
They found a release valve.
Like you couldn't be – the Soviet Union was going to collapse because it's a terrible system, right?
Economically, politically, whatever.
And China found this little bit of balance where they still have the repressive dictatorship but they give enough freedom for people to be ambitious and try to get ahead and that improves the economy and they make some terrible mistakes, right?
There are these huge cities that are built and no one lives there, right?
And there's these spooky pictures, right?
joe rogan
Trevor Burrus You've seen the recreations of other large cities like Paris?
sean carroll
I've seen that.
That's the weirdest thing.
And sometimes like cities like Shenzhen, like right next to Hong Kong, it's a city of 5 million people that 30 years ago was 50,000 people, right?
Like it just – they built it in a couple of years.
And other places like, oh, we'll build a shopping mall here and it's just instantly – it looks like Detroit the next day.
There's no one there and no one makes – No one builds anything.
No one does anything.
Because it's not really capitalism.
It's still a planned economy and there's pluses and minuses for that, no doubt.
joe rogan
One of the big fears about China is their experimentation with genetics.
Is that they're willing to do things ethically that scientists in America and a lot of parts of the Western world are not willing to engage in yet.
Including the use of CRISPR on human embryos.
sean carroll
Yep.
And I think – so I have mixed feelings about that.
I think it's going to happen in all cultures.
I think we're going to do it, right?
I actually had – sorry, I haven't released that podcast yet but stay tuned.
I have an excellent podcast coming with Carl Zimmer who is a science writer who just wrote a long book about heredity and genetics.
And yeah, so what they're going to be doing with the designer babies, it's not science fiction as far as I can tell.
It's going to happen.
But it's very unclear what it will mean because we're not any good right now at figuring out how genetics turns – how your DNA turns into a person, right?
joe rogan
Yeah.
sean carroll
It might be that we find something that if you change this particular gene, sure, you can live twice as long, but also you'll have Parkinson's disease when you're 14. We don't know what the interdependencies are and stuff like that.
But it's coming.
I think that the idea that we will be choosing embryos to come to term and be people on the basis of their genes before they're implanted in A uterus is 100 percent.
That's going to happen.
And the chance that we're going to be editing them is 99.99 percent chance.
And you're right.
China is way more willing to do that.
And again, I'm not really sure that's good or bad.
I think it's going to come here.
What I'm more worried about is that people figure out a system that will make – you can have a baby who's guaranteed to be tall and beautiful and smart and live for 150 years and it will cost you a million dollars.
Then that will be a little bit unfair, right?
That will be an issue that will come up.
joe rogan
Yeah.
But then isn't it unfair that The Rock is The Rock?
How did he get to be The Rock?
sean carroll
It is.
But I think psychologically, I think he worked hard.
joe rogan
He also had some benefit.
sean carroll
He started in the right place.
You know the story of Yao Ming, right?
joe rogan
No.
sean carroll
So Yao Ming, the basketball player from China, he was basically the result of a breeding program.
joe rogan
Really?
sean carroll
Like, they encouraged his parents, who were both really tall basketball players, to have a baby.
And, you know, it worked for him.
It doesn't always work.
It's a crapshoot.
But it can work, yeah.
joe rogan
But that's normal breeding.
That's like, I have a dog, and my dog's a good-looking dog.
You have a dog of the same breed.
Let's put them together.
sean carroll
That's right.
With human beings, but yes.
Otherwise normal.
Yes.
And I think it's different...
It's different psychologically because we think it's different winning the lottery than already being rich and therefore being able to afford something that changes who you are.
I think that – I don't know.
Maybe I'm wrong.
Maybe people will think that that's awesome and these people will be celebrities and we'll follow them on Instagram.
I suspect people will be rubbed the wrong way at that kind of access to something that most people can't afford.
joe rogan
They most certainly will.
They most certainly will.
But I think if you look at it objectively, if you look at the interactions of the species as a completely outside observer, you would say not only is this inevitable, but this is going to lead to some really spectacular changes in what a human being is.
Think about a big part of what we're concerned with constantly on a daily basis is health care, right?
People are very concerned with people that have to deal with debilitating diseases.
If we could just eliminate all those, why wouldn't you want that?
sean carroll
Yeah, I think you probably will be able to, and it will probably happen.
That I think is – but then almost everyone agrees with that.
Like that's not the controversial part, right?
Like, yeah, if we can eliminate – and apparently – Some diseases we already know, like right there in your DNA, you're going to get Huntington's when you're 40 years old, right?
And so those are easy to eliminate, peanut allergies or something like that.
Other diseases are harder.
We don't know what causes them, so it'll take time.
But I think that that would be uncontroversial if you could just remove diseases from people ahead of time.
It's a little bit different if you're choosing their hair color and skin color and shape of their nose and feet and whatever.
That gets...
joe rogan
It does get squirrely, but it's also, you know, the idea of it being a cost-prohibitive issue.
Well, isn't that the case with almost all technology as it emerges?
Remember when plasma TVs were like $20,000 for a small television?
I remember I saw them.
It was only like a 30-inch television or something that was exorbitant.
And I was like, this is incredible.
Like, look at it.
It's flat.
It hangs on the wall.
This is incredible.
But now, everybody has them.
And they're cheap.
You can get one for a few hundred bucks, and it's way bigger and way better than what it was back then.
sean carroll
Yeah, and I think actually that's very realistic, that maybe it will be a million dollars, but then 10 years later it will be $100,000.
joe rogan
It has to sort of be a million dollars first.
It kind of just like cell phones, like everything else, it has to be a really expensive thing, and then eventually it trickles down.
Like cell phones and becomes available everywhere to everybody.
Like if you look at the average person's cell phone, if you buy a cheap cell phone for like 300 bucks, it is way better than an iPhone from 10 years ago.
You know, it's just in every way.
sean carroll
Yeah.
No, I think that's probably right.
And I think that it's one of the things that's happening.
Like we're still the beginning of technology, right?
Like technology is not that advanced compared to where it's going to be.
You know, I have another podcast guest coming up who is an expert on aging.
And how we can fix that by messing with genes a little bit.
joe rogan
Was it Aubrey de Grey?
sean carroll
No.
No.
This was a real scientist at Princeton.
You know, someone who's just doing experiments.
joe rogan
Isn't he a real scientist?
sean carroll
Well, he's – I don't know him that well, so I shouldn't say.
But I think of him as an advocate for anti-aging.
joe rogan
Yeah.
sean carroll
Which is good.
Which is cool.
But my guest, Colleen Murphy, is just like a biologist who's working on things and discovered something, right?
Like she's not trying that hard.
You knock out a certain gene in the certain worm and it lives twice as long and without any decay, right?
Like it doesn't get old because it's fascinating.
Why do we die?
Why do we grow old?
It's not necessary.
You could design an organism that doesn't get older.
It would die from random bad things.
You get hit on the head with a brick.
But you don't need to die.
The reality is that evolution programmed aging and death into us because once we have kids or once we've outlived our reproductive lifespan, we're not useful anymore.
So biology wants us to die.
And so in other words, it's potentially fixable.
It might not be easy.
It might not happen 100 years from now, but it could.
So I think that aging, genetic engineering, brain-computer interfaces, all that stuff is going to – within the next 100 years totally change what it means to be a human being and we're totally not ready for it.
And so I was saying this to Carl.
Carl is like not that – Carl Zimmer is more or less sanguine about it.
He's like, don't worry.
Just we'll put regulations on.
It will be fine.
My attitude was, no, actually we should think of the absolute craziest science fiction scenarios because I want to be prepared, right?
Even if it doesn't come to pass, I want to worry about the least probable things because it might spark something that actually helps us down the road.
joe rogan
Yeah, there was a recent discovery.
They figured out a way to shut off whatever it is that causes wrinkles and reverse the process.
So whatever is causing your skin to get wrinkly and sag, they're reversing that process.
sean carroll
We might be members of the last generation to die.
joe rogan
Whoa.
Or of old age.
unidentified
Right.
joe rogan
We won't be immortal.
sean carroll
Well, then if you thought you were immortal, if you thought – well, let's say you thought that your average lifespan was a million years.
Would you suddenly become way more cautious?
joe rogan
I'd start jumping off buildings and shit.
Yeah.
I have a friend of mine who does that flying squirrel suit stuff.
He holds the world record.
sean carroll
You don't become invulnerable, you just don't age.
joe rogan
Yes, exactly.
sean carroll
That flying squirrel stuff is truly dangerous.
joe rogan
Oh, it's super dangerous.
unidentified
Base jumping, right?
joe rogan
What if they could just fix you?
sean carroll
But that's a separate thing.
Yes, that's possible, right?
Like maybe they could back you up.
joe rogan
Take your goo.
sean carroll
Back you up and then you just dive and they build your clone, put you back together.
Like all these crazy science fictions here.
I don't think that that's – I think that backing up is way harder than people think.
And I think that stopping aging is way easier than people think.
But we'll see.
joe rogan
I agree with you.
I went to the 2045, I think they're calling it, conference in New York City a few years back ago.
It's all the Ray Kurzweil advocates that think you're going to download brains into computers and stuff.
Not that compelling.
That stuff, I was like, what are you going to do?
What's going to happen?
It seems like everybody had this idea of one day we'll be able to do this and we'll be able to take consciousness.
And I'm like, yeah.
sean carroll
Maybe.
It doesn't violate the laws of physics, but it's hopelessly impractical compared to anything we can do right now.
The human brain is just not something you can read out, right?
joe rogan
Well, my question, and this was something that really concerned me, was what's to keep someone from making hundreds of thousands of versions of themselves?
Like, what if it takes someone from some, you know, really rich billionaire character that can afford to do this and say, I'm going to do this many, many times.
Then I'm going to have my clones make clones of clones, and I'm going to fill up a whole island with me.
sean carroll
Why would you do that, though?
joe rogan
Because you're a crazy person.
sean carroll
Okay, I mean, crazy people are allowed to do crazy things, right?
joe rogan
But imagine if you had a hundred Sean Carrolls in your house working on things.
sean carroll
But they're not the same person.
joe rogan
What if you found out that 30 of the Sean Carrolls were smoking crack, and banging hookers, and driving fast on the highway in the wrong direction?
sean carroll
Can you imagine?
joe rogan
Have you realized that after a while, there is a randomness, DV being you?
Sure.
sean carroll
Yeah, it's Evo Devo, right.
The environment you grow up in matters.
joe rogan
That would be really fascinating.
That would be an excellent episode of Black Mirror, where someone clones We're good to go.
There's a real concern with messing with biology in a way that's never been done before.
sean carroll
Exactly.
And I think that the extent to which it's coming is something we haven't quite faced up to yet.
joe rogan
Right.
sean carroll
And it's really coming.
It's coming fast and profoundly.
We're not ready.
joe rogan
Yeah.
And the possibility of just...
Creating a world that we're not prepared for and we're not prepared for the consequences of.
sean carroll
Yeah, exactly.
So that's why I'm all in favor of thinking crazy, right?
Like just wondering what it would be like.
Even if the answer is no, that will never happen.
At least be prepared a little bit.
Think of all the alarmist crazy scenarios.
unidentified
Yeah.
joe rogan
Have you really gotten into CRISPR? Have you really looked into that stuff at all?
sean carroll
Not that much, you know.
It's a little too applied, a little too real world for my taste.
joe rogan
For people to know what we're talking about, it's a new technique for editing genes that was discovered accidentally while examining the effects of...
sean carroll
The story is amazing.
I mean, there are these bacteria.
So here's the thing.
We think of DNA as where our genetic information is stored, right?
You have a little code.
It's a little list of symbols, A, C, G, T. And they're in a row and that's it.
It is handed down from parents to children.
But the reality is way more complicated than that because different parts of the DNA do things and different ones don't.
Some of them get turned on and turned off.
We have mitochondrial DNA, which are not our DNA. We have these little sub-cells within us that get carried along for the ride and have their own DNA. And So CRISPR is this thing that was invented by nature, right?
Not by human beings.
These bacteria who were trying to resist viruses, right?
So the viruses would come in and attack them.
And basically the bacteria learned a way to steal part of the DNA of the virus and keep it as like a facial recognition software thing.
It's like a template like, oh, this DNA thing is approaching me.
That's a virus and I should attack it, right?
Like this is something that I learn how to fight off.
And so to do that, you need to be able to snip out a little piece of DNA.
And so scientists, biologists learned that they could train.
This is a little bit fanciful way of putting it, metaphorical.
But they could train the bacteria to go in there, snip out pieces of DNA and you can do that for any DNA you want.
And you can replace it with something else.
It's not really very high precision right now, but that's coming.
And so in principle, this is a little way to change a genetic code.
And then they figured out some other way that ordinarily, right, if you have two parents and you have like brown eyes versus blue eyes and blue eyes are recessive.
So they both need to have the blue eye gene to give you if you want to have blue eyes.
But they figured out a way that you can change the DNA and it automatically with 100 percent accuracy gets sent to all of your offspring, right?
It's not 50-50 chance or whatever.
So then you can just propagate a change in the genetic code throughout the species pretty darn quickly.
Human beings take a long time to breed, but animals and plants, it's a whole other world, right?
You can design those very, very rapidly.
joe rogan
And there's already been at least one revision of the process, right?
sean carroll
I think so.
But yeah, I think I just told you everything I know about it.
joe rogan
I think they're continuing to improve on the process.
And it's really going to be very interesting to see where that goes as that advances.
Yeah, I think this was a concern with places like China.
They're already doing this.
They're already manipulating genetics and trying to create super people.
sean carroll
And I think that the chances that gives them a great basketball team are greater than the chances that give them a bunch of brilliant PhD scientists.
joe rogan
Well, that's where it starts, right?
A lot of it starts in competitive athletics.
Have you paid attention?
Did you watch the documentary Icarus?
sean carroll
No, I did not.
joe rogan
A fascinating documentary that's on Netflix right now about...
It really is kind of a crazy set of circumstances.
There's a guy named Brian Fogle.
He's the director and the producer of the movie.
And he was a competitive bike racer.
And he decided to document what he wanted to do was compete in a race, a bike race, 100% clean, and then get a Russian scientist to juice him up.
So in the process of getting this Russian scientist to juice him up, he stumbled upon a scandal.
And in the middle of him making this...
Yeah, but I mean, in a crazy way, because this Russian guy is the head of the anti-doping agency in Russia.
And he was just sort of informing him how you would do this.
So he teaches him, informs him how you can do this.
While this is all going on, it turns out that the Russians had completely cheated their way through the Sochi Olympics.
And it was all documented.
And so they were getting busted as this is all going on.
And he films this Russian guy who's the head of it escaping Russia...
And being chased and testifying all the different strategies that the Russians used in order to completely cheat on like at least one entire Olympic team.
Like every single athlete was on drugs.
And they had a record number of gold medals.
And so then he starts detailing the process and how they did it.
And these forensic tests examined the urine bottles and showed that they've been opened, even though they were supposedly not openable.
And really, really interesting stuff.
But that national pride, the thing about national pride and the ability to win a bunch of gold medals and athletic dominance is so important for the morale of these countries that want to establish superiority.
sean carroll
Right.
Yeah, and there are some people who say, well, let's just go for it.
Let's just have the all-dope Olympics, right?
Like let people enhance themselves as much as they possibly can.
And there's an ongoing debate about what about people who use prosthetics, right?
Is that fair?
If you lost a leg and you have a prosthetic leg, could that potentially give you an advantage in a running event or something like that if it were a sufficiently good prosthetic?
I don't know the answer to any of these questions.
I think it's a little bit weird because – We set up these arbitrary categories for what is a sporting event and we invented them, right?
They're not out there in the world and now we're faced with wholly different circumstances to what to do about it.
But yeah, I think that there's the question of what we should do, which is hard.
There's the question of what's going to happen, which is it's all going to happen.
All these things are going to happen.
joe rogan
I was talking to a guy this past weekend who's a Navy SEAL, and his friend lost his hand.
And they gave him a new hand.
And they're working on this new hand now that's going to allow him to play piano.
So it's a completely artificial carbon fiber hand with all these different things that attach directly to your nerves.
And somehow or another, he can control it with his arm that's going to allow him to play piano.
sean carroll
And you're going to tell me he could never play the piano before.
unidentified
Right.
joe rogan
Now he knows how.
sean carroll
It's programmed.
joe rogan
It's in the thing.
sean carroll
Well, this is what I was saying about the brain-computer interfaces.
I think that's the real – that's even bigger frontier than synthetic biology or genetic engineering because computers are really useful for things.
Robots are very useful for things.
Human beings are just going to sort of blend in.
It's not like we're going to have AI and super healthy humans.
It's we're going to just have everywhere on that spectrum.
joe rogan
Yeah, that's what I'm thinking as well.
There's going to be some sort of a symbiotic thing like a chip or, you know, they tried it with the Google glasses to try to get people to wear it, but they were goofy.
I put them on.
They felt too science fiction-y.
sean carroll
Just like the first portable phones were these giant things, right?
That doesn't mean, right?
That's not a long-term prognostication tool.
Yeah.
Lots of people are working on it.
Elon Musk has a little company that no one knows about.
Well, they do now.
Well, people know about it if they care, but it's not like one of his famous ones, right?
To implant neural lace, right?
To put something in your body that reads your brain.
joe rogan
Neural lace.
I don't like the way that sounds.
Where does it go?
sean carroll
You wanted more macho?
joe rogan
You pointed the back of your head, too.
sean carroll
Yeah, you open up your skull.
joe rogan
No, I didn't think of it in terms of lace.
I didn't think of it as lingerie.
I was thinking of it as like a mesh.
sean carroll
Yeah, that's the idea.
joe rogan
It just seems creepy that it's going to latch on your nerves.
sean carroll
Yeah, and improve you.
joe rogan
Neural lace.
sean carroll
You won't need your phone anymore.
joe rogan
Wow.
And you went to the back of your head.
Everyone goes to the back of their head.
unidentified
Well, the front of my head is useful for something else.
joe rogan
But I mean like the matrix, everybody goes to the back of the head.
sean carroll
Yeah.
I mean right now, companies that want to make money in the short term are building these non-surgical, non-invasive things.
We like wear something on the front of your head or wear a cap or something like that.
Which can detect frequencies of vibrations in your brain, and it's very primitive, but you can move things around.
You can control drones, right, with your brain without touching anything.
But yeah, if it ever becomes practical, which is very far from certain, but the thing to imagine in the far-out science fiction scenario is cracking open your skull, inserting some electrodes in there, closing it back up, and now you're part of the super internet without doing anything more than closing your eyes.
joe rogan
Yeah, and there's also the possibility of enhancing various thought processes, too, with transdermal stimulation.
You know they're doing that now.
They've performed a series of tests where they have people do certain tasks, and then they put electrodes into certain areas of the brain and put an electric charge, and that electric charge stimulates various aspects of the brain and then allows them to complete certain tasks quicker and more efficiently.
sean carroll
I think – and this is just kind of uninformed belief.
But I suspect that the human brain is pretty optimized for what it tries to do.
I think that rather than improving the brain or stimulating it, the way forward is to augment it, like hook it up to calculators and internet and whatever.
One thing that – I don't see talked about very much, but I think will be a real game changer.
We talk about phones as if we're carrying around phones, but we don't mostly use our phones to talk to people on the phone, right?
We check the email, check the internet, and we take pictures.
Once you really have, and again, it might not be possible, but if you really had a direct connection between your brain and the internet, your eyeballs are a video camera.
Everything you see you can record and store somewhere, right?
So – and you can lend them to other people or people can subpoena them or whatever.
Like there's literally no place in the world that human eyeballs aren't looking at that would not be subject to later inspection.
That is weird and scary and bad, right?
joe rogan
It is weird and scary and bad.
And what if someone comes up with a better eyeball?
sean carroll
Oh yeah, of course.
joe rogan
They let you scoop out your old dull eyes and put in some new awesome ones that you can record with?
sean carroll
Yeah, absolutely.
joe rogan
Yeah.
I don't think that...
I think I absolutely agree that enhancing it with electronics is probably the way to go and that having some sort of symbiotic relationship with electronics.
But I also think that this transdermal stimulation can enhance that process on top of it.
I think there's going to be a bunch of different things going on at once.
I mean, if you think about...
where someone eventually figures out a way to design various aspects of the human brain that are more open to interface with technology, changing various receptors, make them more efficient for data to go straight to the dome.
sean carroll
Yeah, and I think that there is a short-term versus long-term question here, right?
Like even if what I said is a long-term truth, on the short-term, improving our thinking skills in direct ways with stimulation or whatever sounds pretty good.
But maybe you can just do that through beta blockers or some drugs or something like that.
Like I think that that's another thing very plausible that we'll have safe, super-efficient drugs someone can take in over the next six hours.
They're way clearer thinkers than they were before, right?
joe rogan
Is there any concern with what's the endgame?
I hope so.
sean carroll
Yeah, I hope so.
I mean, if you're super far advanced, the endgame is you realize that life is not that interesting.
joe rogan
You went too far.
sean carroll
Yeah, you're like, well, why am I here?
What am I doing with all this?
Yeah, a little challenge is helpful, actually.
Well, in particular, if you develop immortality, if there's no concern about getting injured or killed, I think that people who envision super far ahead science fiction scenarios and especially people who envision uploading brains and consciousness underestimate the importance of our bodies to who we are as human beings, right?
Not just that we're in a body but like hunger, I don't think it will be anything like the personality, the person who you are if your body is taken away.
joe rogan
That's the big question about artificial intelligence.
We have very specific needs that are addressed by our ambitions.
Biological needs, the idea of transferring your genes, keeping your bloodline going, all that stuff.
There's all these survival instincts that we have that you wouldn't necessarily have if you were an artificial life form.
Why would you care if someone pulled the plug on you?
Why would you try to survive?
What's your purpose here?
sean carroll
Right, exactly.
joe rogan
It seems sort of futile.
sean carroll
There's a lot of talk in the AI existential risk community, like worrying about artificial intelligence, about value alignment, like making sure that the AI's Value the same things that we do, like our existence, for example, right?
But I think a little bit, at least what I hear, and I'm not an expert, but what I hear seems a little bit off the mark because they're talking about what to program into the AI. But if it's in any sense really an AI, it can reprogram itself.
Right?
You can change your mind as a human being.
You can change your values.
You can change your motivations.
Artificial intelligences should be able to do the same thing.
And in fact, they better be able to do that if they're going to be truly intelligent, if they're going to mimic what a human being can do.
It can't be something where we program them to just do a task because that's not intelligent, right?
So if that happens, yeah, then who knows what they're going to eventually be motivated to do if anything.
Like you said, like what is their motivation even to do anything at all or even to exist?
joe rogan
Well, isn't one of the big concerns is that in releasing artificial technology and giving it autonomy that what we're going to do is start a process that's some sort of a perpetual exponential domino effect Of technology where this new artificial life is going to create better artificial life,
which creates better artificial life, which expands to godlike powers within a very short period of time and decides we're stupid and useless and just eliminates us.
sean carroll
And then it gets bored and shuts itself off.
joe rogan
Yeah, it goes, what are we doing here?
The sun's going to burn out in X amount of billion years.
sean carroll
These are hard things to even extrapolate because they're so far beyond our experience.
But I do think that We're opening up doors that we never have before between genetic modifications of human beings, artificial intelligence, brain-computer interfaces.
We don't have the experience or the capacity to really even ask the right questions about these things.
unidentified
Right.
joe rogan
We're sort of rudimentary.
The ideas that we have of what is necessary are really based on our own biological needs.
We have family.
We want to keep everybody healthy.
We enjoy our community.
We want to keep it safe.
We enjoy our earth.
We want to keep it clean.
We want to save things for the future generations.
And all these concerns that we have that are very biological, they just won't exist for artificial life.
sean carroll
I think that's exactly right and I think that what we're really good at or what we're better at in terms of imagining the future is taking what already exists and just expanding it, right?
Like so when people – I think maybe we talked about this on the last podcast.
But when people first started imagining mechanical devices to carry you around, mechanical transportation in the late 1800s, They imagined a mechanical horse because they knew that horses existed, right?
And the car was a totally different thing and people hadn't thought of that originally.
And then when people did think of cars, they thought of flying cars because they saw they were flying animals, right?
And the flying cars haven't appeared because we didn't – what they should have been thinking about is how are cars going to change our cities and our commutes and how we live, right?
When people invented the internet, they weren't sure what they were going to do with it.
And I think that the same thing is true when – If we can imagine blending the barrier between our biological existence and some virtual existence, we don't even know what questions to ask about that.
joe rogan
Yeah.
And I think we are getting close to those other things that you mentioned, though.
Boston Dynamics is getting really close to artificial dogs and artificial horses.
I mean, they have things that you can't kick.
You kick them and they don't get knocked over.
sean carroll
They can open doors.
joe rogan
Yes.
They can jump incredible distances, incredible heights.
There's some amazing ones that do acrobatics now.
Have you seen that?
Where they're going to replace stuntmen in movies that could potentially get harmed with these robots that can do crazy backflips and jump off buildings.
sean carroll
The next big war is going to look very, very different than the last big war.
joe rogan
Hopefully it won't happen.
But if it does, yeah, there's a big emphasis on automated things, not just drones, but physical things that are running around on the ground.
sean carroll
You can make decisions, right?
Give it a little bit of AI. Do you watch Dark Mirror?
I haven't seen it.
It's in my queue.
joe rogan
There's an insane episode on...
Do you remember the name of it?
Black Mirror?
Black Mirror.
Did I say Dark Mirror?
Yeah.
Black Mirror.
this insane episode on these little robots that are chasing metal face metal head something like that yeah it's about robots chasing after this lady It literally is these little tiny Boston dynamic robots, but they can kill you.
sean carroll
Yeah.
joe rogan
And they're on a mission.
And this is not outside the realm of possibility at all.
sean carroll
Nope.
It really isn't.
And like I said, we don't even know.
It's easy to extrapolate right ahead to sort of the simple differences.
joe rogan
There it is.
That's from the episode.
It's a fantastic episode, too.
There's so many good episodes of that show.
Black Mirror is just amazing.
sean carroll
Yeah, I gotta start watching that.
joe rogan
But that's a concern.
I mean, there's a real concern.
I mean, we're doing it right now with drones.
You know, if you talk to people that have paid attention and studied drone warfare and how Incredibly inhumane it is and how different it is from any other type of warfare in terms of the ability to rationalize targets when you're not there and you're nowhere near and you're just pressing buttons and you decide, well, there's a very good possibility this person's in here.
Fuck it.
Nuke the building.
sean carroll
Yeah.
I think we're doing that.
joe rogan
Yes.
sean carroll
That's absolutely happening.
But on the other hand, the drones are also delivering pizzas.
joe rogan
Are they, though?
sean carroll
I think so.
joe rogan
Who's gotten a pizza with a drone?
sean carroll
I think so.
joe rogan
If you looked at the amount of people that have delivered pizzas with drones versus the amount of people that have been killed by drones...
sean carroll
Probably the killing is bigger.
joe rogan
Well, the innocents are the scariest.
Drones are really good at killing innocent people.
Not so good at killing the people that are specific targets.
sean carroll
But I think my point is just that there are going to be pluses and minuses, right?
unidentified
Yes, for sure.
sean carroll
So I think that it's going to change...
Like, if we combine this idea of...
You know, interfacing with computers, with this idea of drones doing some drudgery work, with this idea of giving people a basic income, everyone is just gonna sit in their rooms and write on their tumblers all day.
That's gonna be the future.
joe rogan
I don't think they're going to be writing anymore.
I think there's a real possibility that we're going to create virtual reality that's indistinguishable from regular reality and people are going to live in there like Ready Player One.
Well, it'll be better.
sean carroll
I think the big flaw to me in things like Tron or Ready Player One is that they make the virtual reality look too much like the real reality.
There's no reason why virtual reality has to have gravity.
There's no reason why it has to be three-dimensional.
There's no reason why you have any limit on how strong you are or how fast you are or anything like that.
There's no reason why you have to have only one body.
I mean, there's a million different ways in which it could be very, very different.
joe rogan
Well, it also could be implemented with something like the tank, the float tank that we were talking about earlier.
I mean, you could climb into that float tank with some sort of apparatus, hook these gloves on, put this helmet over, and literally not be subject to the whims of gravity.
You can't even feel it.
The effects of gravity will be inconsequential because you will feel like you're floating, and then from there you'll be able to fly around and do all sorts of...
sean carroll
Yeah, I think like this weird period between the year 1900 and 2000 or 2100 or whatever it's going to be, it will be a weird transitional period in human history where we invented technology and not really put it to work yet.
And there might be some equilibrium that we reach in 100 or 200 years where the whole mode of life is utterly different than what it is now.
joe rogan
If you could put priorities in terms of like what you think people should concentrate on first, In regards to this kind of stuff, what do you think those would be?
If someone said, Sean, you're a super smart dude, let's get on the ball here and figure out what direction should we take this in?
sean carroll
I mean, what I do for a living is more like foundational, what are the laws of physics kind of things, right?
So I'm not the person to speculate on this stuff.
unidentified
But who is?
sean carroll
Well, I think this is why I said earlier, I think we should be talking to each other because nobody is.
No one person is, right?
That's why we need to have people from different areas of expertise talk about each other's areas, if only then to be corrected, right?
But to be open to that dialogue.
So I think that For example, an enormous amount of effort has been put into nanotechnology, building tiny little machines.
I suspect that mostly the real advances there are not going to be in nanotechnology but in synthetic biology where you take bacteria or multicellular organisms that already exist and adapt them for your purposes.
Make them do whatever you want because biology has already solved a lot of the problems that technology is still struggling to figure out.
joe rogan
So the concept of nanotechnology is you're going to take almost like a cell-sized machine and many of them are going to go into your body and find areas that are damaged or that are problems.
sean carroll
Or do whatever.
unidentified
Yeah.
sean carroll
There's a woman, a professor at Caltech who gave a talk a few months ago about she builds robots out of DNA.
So these little DNA robots can go in and right now they're at the level where what they can do is sort things.
So like if they have molecule one and molecule two scattered across some surface, this little DNA robot will go in and move all molecule one to the left, all of molecule two to the right.
And so she says that's the beginning – Like in the future, you'll have your little DNA box and you'll say, you know, I'm allergic to tomatoes.
And then it will invent a little machine that will run through your body and fix your allergy to tomatoes, right?
You don't need that anymore.
joe rogan
Whoa, with a machine?
sean carroll
With a DNA robot.
So why DNA? Because you think of DNA as carrying the genetic code, but DNA is a wonderful molecule because it is relatively stable, but it's not just a crystal, right?
It's not just doing the same thing over and over again.
So it contains information.
And it can adapt.
It can hold on and grab on to certain things and let go and do things.
So DNA is a wonderful testing ground for building little, really, really tiny things in your body that will change who you are.
joe rogan
Well, here's a question that's not totally related, but you might be a good person for this.
unidentified
What is quantum computing?
joe rogan
Now, I keep hearing about this.
It's one of the big breakthroughs in computers is going to be quantum computing.
sean carroll
Right.
I'm almost the right guy.
I'm not completely the right guy.
I actually did teach a course at Caltech that involved quantum computing.
So I'm above average.
joe rogan
Definitely the best guy to do that.
sean carroll
But yeah.
So quantum mechanics.
This is the book that I'm writing right now.
It's going to be out a year from now called Something Deeply Hidden.
It will be about quantum mechanics and the goal of the book will be to make quantum mechanics understandable to everybody.
and convince them that quantum mechanics really does imply the existence of multiple worlds where things look very much the same except for tiny differences.
And one way of thinking about what quantum mechanics says is in classical mechanics, which is what came before quantum mechanics, let's imagine you have a bit, right, that is something is either zero or one, right, one piece of information.
In quantum mechanics, you have a quantum bit, a qubit as they call it.
Very clever.
So the difference is that instead of it being a zero or a one like it would be classically, quantum mechanically, it is in some superposition of zero and one.
It's some combination of a little bit zero, a little bit one.
And it's not that you don't know which one it is.
It's that it really is both.
It might be 90 percent zero and 10 percent one or something like that.
So take that fact, number one, okay?
Fact number two is that quantum mechanics has a thing called entanglement.
Which means that if you have two bits, classically, so you have 00, 01, 10, 11, right?
Four different possibilities.
So quantum mechanics says it's not that this one bit is in a combination of 0 and 1 and this other bit is also in a combination of 0 and 1. It's that the two-bit system is in a combination of 00, 01, 10, 11, right?
So it might be that it's 50 percent 00 and 50 percent 11. So you don't know what either bit is but you know they're the same, right?
So that's entanglement.
So you take these two ideas that you have a combination of zeros and ones rather than just one or the other and the different bits can be entangled with each other and then you just say, well, what is a computer?
A computer is something that takes bits in, does manipulations and spits out the answer, right?
You solve problems.
That's what's literally going on in your computer is a bunch of zeros and ones being pushed around.
So a quantum computer is pushing around a bunch of qubits, right?
A bunch of spinning particles or something like that.
The spin of a particle that can either be spinning clockwise or counterclockwise is a qubit.
And so these particles can interact with each other.
They can become entangled and you invent a quantum algorithm, right?
Like there's algorithms for finding the area of a surface or something like that, factoring large numbers, solving the shortest distance between two different points.
You can do this using the rules of quantum mechanics instead of the rules of classical mechanics and the belief Which is not yet 100% established, but we think is true.
There are some problems that are really, really hard to solve for a classical computer, which means that you can easily make the problem long enough that it would take the lifetime of the universe to solve it on a classical computer.
Which quantum computers can solve quite quickly and efficiently.
And so it's – we're not – we haven't proven that.
It's not a mathematically precise statement.
joe rogan
Why would they think that quantum computers would be able to solve it quicker?
sean carroll
There's more information in the quantum computer.
Like if you have two bits, zero, zero, zero, one, et cetera, there's only four things it can be, right?
If you have a quantum computer, there's an infinite number of things it can be because it's any combination of those four things, right?
10% this, 20% that.
So there's like a continuum of possibilities.
It's analog rather than digital in some sense.
And so what you can do, the quantum computer can just sort of – Take advantage of that extra power to look – I mean because of this entanglement, this is – I'm going to get in trouble with my quantum computing friends because it's not quite fair.
But roughly speaking, rather than manipulating bit by bit, because of the entanglement between the bits, the quantum computer can move all the bits a little bit at once.
So let's say that you're searching for something in a list, right?
A very elementary computer science program is I'm giving you a list, find an element that is equal to a certain number, right?
It sounds easy, but if that list is 10 trillion things long, that's hard, right?
unidentified
Right.
sean carroll
So what the quantum computer can do is say take every element in the list, nudge it a little bit towards zero if it's the wrong answer and towards one if it's the right answer.
And you don't know where it is in the list, but you can do that nudging over and over again.
And at the end of the day, you look for where is the one.
It's very easy to find.
So you can get the answer much quicker, it is believed.
And so things like cryptography, privacy, right, are dramatically changed by this because one of the things that we think quantum computers should be able to do faster is factor large numbers, which is the – the difficulty in factoring large numbers is the basis for much modern cryptography.
But also simulating systems that were just too difficult to simulate.
It took too much computer power to do it.
Now maybe we can do it because nature is truly quantum mechanical at the core.
It turns out to be very hard because the problem is you have all these bits.
If you touch one of them, if the outside world bumps into one of them, like a cosmic ray or an atom hits it, the whole entanglement is ruined between everything.
So it's very, very delicate.
And that's what the – right now they're working on systems of let's say dozens of qubits entangled at once.
You would like it to be way more than that because you can store an enormous amount of information in these things.
If it works, I think it will be way better at computing if it works.
I'm not at all sure that quantum computers will be efficient or cost-effective or anything like that in the near term.
But doing computations faster is something that a lot of people wouldn't be able to do.
joe rogan
So right now they're working with dozens of qubits.
And what's preventing them from expanding that?
Or are they doing it slowly to sort of make sure that it all works correctly and get an accurate model?
sean carroll
Yeah.
So the problem is if you have a qubit, it can be in a combination of zero or one, right?
Any combination whatsoever.
But as soon as you look at it, you never see the combination.
You see zero or you see one.
That's it.
And you've ruined – you've erased this preexisting combination.
If you see zero, now it's in the state zero.
If you see one, it's in the state one.
So if you have a group of many, many qubits, what I mean by look at is literally anything else in the world bumping into it.
So like I said, if photons hit it, if particles – if molecules of air and oxygen or nitrogen bump into the qubit, that will count as an observation and it will collapse as we say.
It collapses the wave function and all of your quantum information is ruined.
So you have to make them sort of very cold, very isolated, very shielded from external influences and the more qubits you add, the harder that is to do.
joe rogan
Now is there a proof of concept to this?
sean carroll
Yep.
They have working quantum computers.
I forget – there was a joke.
Scott Aronson, who's a friend of mine who's a genius theoretical computer scientist, used to joke that the quantum computers are able to say that the number 15 is equal to five times three with very high probability.
That was the state of the art.
I think they're able to say that 21 equals 3 times 7 with very high probability now.
But what you would like to say is some 100-digit number is the product of two other numbers.
They're not able to do that right now.
joe rogan
Now, what are they looking at with this?
When they're looking in terms of the future, this stuff, how do they want to implement this?
sean carroll
Lots of different ways actually, like the actual physical technology that they're using.
Some people are using atoms.
Some people are using sort of features of condensed matter systems like two-dimensional systems where electrons are moving slowly and can wind around each other and things like that.
This is way beyond what I actually know about.
But also the sort of sidelight of this is that this existence of entanglement It's kind of a shared information between two different things in a way that classical physics just would not allow.
And that's interesting and exciting because it opens up ways for sharing information that other people can't get to because you have some information, your friend has some information, but you need both pieces of it to get to it, right?
Right.
Seth Lloyd, who's another friend of mine, an MIT professor, said that he was – he tells a story where he was in a hot tub with the Google guys, right?
With Sergey and Larry and the heads of Google, the founders.
And he said, oh, I came up with this brilliant new idea where we can use quantum mechanics, build a quantum computer so that a person who does a search – A Google search using this quantum computer, they can do a search and they can get their answer, but it is literally impossible for anyone else to ever know what they searched for.
And the Google guys were very excited, and they went away.
The next day they came back and said, oh, we realize this is the opposite of our business model.
It's really important to us that we know what you search for.
joe rogan
Yeah, right?
I mean, that's the whole thing with them.
Google Adsense.
When you go to another website, it shows you, oh, Sean's been looking at Lenovo laptops.
Bam, there they are.
sean carroll
Yeah, and they follow you around on all your other devices.
joe rogan
It's weird.
sean carroll
Your cookies.
joe rogan
Creepy.
sean carroll
But yeah, so in quantum computing, there's quantum money, there's quantum cryptography, there's quantum eavesdropping, things like that.
So it's easy to speculate about.
I would not say the actual technology is very far advanced right now, but I can't tell you how quickly it will happen.
joe rogan
Wouldn't someone like Google just have to adjust?
Because prior to these Google ads, you never really knew what someone was interested in unless they took surveys or unless they had purchasing history.
There had to be some way.
Now they're just detecting off of searches, and that's what their business model is.
But that doesn't mean they can't.
Come up with a better new business model.
sean carroll
They'll have to adapt, but they are not in the business of making that happen.
joe rogan
No.
Especially now it's so effective.
sean carroll
If they were really smart, they would have given Sat the $100,000 and said, tell no one about this ever again.
Right.
joe rogan
Is that enough?
sean carroll
Yeah.
joe rogan
We found out with the Stormy Daniels case that $100,000 doesn't buy a lot of privacy.
sean carroll
Two-thirds of a Stormy Daniels.
unidentified
Right.
joe rogan
What do you think they'll – like what would be the first way they try to use something like this?
They try to use quantum computing.
sean carroll
I don't know.
I think that the people who are really interested in now are the NSA and the DOD, right?
National Security Agency and the Department of Defense because – Secret messages are the most obvious thing.
Cracking codes and things like that.
That's like the killer app that we know about right now.
Physicists of course want to use it to simulate quantum mechanical systems to learn about the behavior of materials like maybe you will build a better superconductor or something like that right away.
Maybe you'll do better designing of your genetically engineered DNA on a quantum computer, right?
Like there's sort of the generic thought that you'll be able to do computations faster.
That's interesting.
Then there's more specific things like if the system you're trying to simulate is itself quantum mechanical, then simulating it on a quantum computer might be the way to go.
joe rogan
Yeah, to most people that just went, woo!
Right over the head.
What are these guys talking about?
Quantum is so weird.
Like one of the things that you said earlier when you were talking about quantum, you were talking about worlds that are very similar but with very small differences.
sean carroll
Right.
Trevor Burrus Yes.
So yeah, I forget whether we talked about this last time.
So there's this whole version of quantum mechanics.
Well, let me back up because we have time, right?
joe rogan
Matthew Feeney Sure.
sean carroll
Trevor Burrus Quantum mechanics is weird because, among other things, it is by far the most successful theory of physics ever invented.
We've tested it to enormous precision, right?
There's zero evidence that quantum mechanics is in any way not right.
But we don't understand it.
We don't – we like – not just people on the street.
Like professional physicists don't know exactly what quantum mechanics says.
joe rogan
So how do you practice it?
sean carroll
Well, we have a recipe.
We have a black box, right?
The way that I put it in the book is imagine you had a website you could go to and you would say – If I threw a ball with a certain velocity in a certain direction, how far would it go?
It would give you the answer right away.
joe rogan
Trevor Burrus Depending upon the atmosphere.
sean carroll
Trevor Burrus Yeah.
You put all the details in, it gives you the answer.
Does that count as you knowing the laws of physics?
No.
You just have a black box, right?
unidentified
Trevor Burrus Right.
sean carroll
Trevor Burrus Well, that's what quantum mechanics is right now.
If we set up an experiment, we can say what the probability of every answer is going to be, every outcome.
But if you say, well, why?
What happened?
We don't know or we don't agree.
Like different people disagree with each other.
And so this version of – there's different versions that try to answer this question.
What's really going on beneath the surface, right?
What's the deep down story of the world?
And one of these stories is the many worlds interpretation of quantum mechanics.
And it was invented by a graduate student, Hugh Everett, in the 1950s who was instantly kicked out of physics.
unidentified
Really?
sean carroll
Yeah.
Oh, yeah.
There's a long, unglorious history of people trying to think deeply about quantum mechanics and being shunned in the community for doing so.
Because we've set up this weird thing where – I mean there was literally a memo that went around the major physics journal in the United States that said we will not even look at papers to try to think about the foundations of quantum mechanics.
It's embarrassing.
It's terrible.
It's like we need to do like real work, like shut up and calculate.
We need to build bombs and things, not think about the nature of reality, which I think is very much antithetical to what physicists should be doing.
But anyway, so what many worlds says is – well, so when we do talk about quantum mechanics, let's say we have a qubit.
We have a spinning particle, right?
We have this combination of spinning clockwise and counterclockwise, and so we call that the wave function.
The wave function is just it's 10% clockwise, 90% counterclockwise or whatever.
So to every possible measurement outcome, you give me a number, and that number is basically how I figure out the probability of that measurement outcome coming true, and that's the wave function.
So for a long time, people thought, well, this is just a trick.
This is just like some – it characterizes our inability to be precise, right?
We have a probability of this, a probability of that.
But someday they hoped – Einstein, for example, had this hope that we'll have a better theory and we'll know exactly how to predict everything with perfect precision.
So whatever it says is no, no, no.
It's the other way around.
This wave function is reality.
That's the whole world, right?
That's what reality is.
It is a superposition, a combination of all the different possible outcomes.
It's not any one outcome.
There's no such thing as where the electron is.
It's all spread out.
And the problem with that is that when you look at the electron spinning, you never see it as a combination of spinning clockwise and counterclockwise.
You always see one or the other.
And Everett says that's because you have a wave function.
You live as a superposition of different possibilities.
And when you look at the electron, what happens is before there was you and there was an electron and a combination of counterclockwise and clockwise.
Afterward, there is the electron was spinning clockwise and you saw it spinning clockwise.
Plus...
That's 10 percent.
Then 90 percent, the electron was spinning counterclockwise and you saw it spinning counterclockwise.
And both possibilities are real but they're separate.
They've branched off from each other.
They've gone their own ways.
They're separate versions of the world, separate copies of reality.
That's why it's called the many worlds interpretation of quantum mechanics.
joe rogan
Trevor Burrus Oh.
Possibilities is always a big feature.
That's the thing that people are constantly discussing, right?
sean carroll
Yeah.
joe rogan
What are the possibilities?
Predicting the possibilities.
And when it comes to human beings, this is also randomly discussed because we talk about determinism versus free will.
We talk about what are the possibilities that is created as Sean Carroll, and why do you think the way you think, and why are you going to say the next thing you're going to say?
And how much of it is biological?
How much of it is your life experience?
How much of it is information that's dancing in your head?
How much of it is you interacting with me, the last thing that I've said to you?
sean carroll
Yeah.
So I had – I was on Sam Harris' podcast.
We had a long conversation about this because he is very anti-free will.
And I think that it's – I disagree with him.
But I don't care.
I think it's kind of boring to be honest.
joe rogan
Do you think it's boring, really?
sean carroll
I think it's boring because – here's why I think it's boring.
Because there's two questions.
One question is how does the world work?
The other question is what words should we attach to how the world works?
Sam and I agree on how the world works, right?
But I am what philosophers call a compatibilist when it comes to free will, which is I don't think that I have some ways of thinking my way into overcoming the laws of physics, right?
Like I'm made of atoms, made of particles that obey the laws of physics.
If I talk about myself, As a large collection of atoms and particles obeying the laws of physics, then clearly there's no free will.
There's just the solution to the equations and sometimes the wave function branches and there's now two of me, but that's whatever it is.
There's no spark of consciousness that lets me overcome what the equations say is going to happen.
Trevor Burrus But guess what?
You grew up in a certain place, you have a certain job, stuff like that.
You dramatically condense the information about who you are into a few salient points.
And among those salient points are, I am a person who thinks and makes decisions.
Every person in the world, no matter how anti-free will they are, talks about people as if they make decisions.
And the reason they do is because that's how people are.
That's the best way to talk about people.
It's not like just a compromise.
Like if you don't know the atoms and molecules in somebody's body and you're not infinitely computationally powerful so you can predict the future, then it's correct to talk about people as agents who make decisions.
We call that free will.
I call that free will.
Most philosophers call it free will.
If you don't want to call it free will, be my guest.
It doesn't really matter to me.
joe rogan
I agree with what you're saying.
I think that makes a lot of sense and I think that really simplifies a very complex issue.
When I looked at it and I have had this conversation with Sam as well, I totally see his point and I think he makes a hundred percent sense.
There's no arguing with it.
I really think it's very rational, that approach.
But I also think that it's very much like What we were talking about earlier, that it's not necessarily just a one or a zero, that it's a combination of these things.
Free will, there is some mechanism that chooses to do one thing versus another.
There is some computation.
There's calculation.
There's debate.
There's discussion.
There's a thing.
Inside of you, whatever it is, whatever that process is that's causing you to – I mean, how many times have people stayed up all night going over and over and over a certain idea trying to find a rational conclusion?
sean carroll
Oh, yeah.
All the time.
joe rogan
Right.
Well, what is that?
Is that free will?
sean carroll
Is that – This is where it actually becomes interesting to talk about the vocabulary we use, right?
Because it becomes very, very hard to know where to attach the word I or you when you're talking about this.
Like we tend to say, I made a decision.
OK, that's fine, right?
I decided to have this can of pure caffeine that you put in front of me and drink it.
I could have decided otherwise.
So that's the question.
Like does it make sense to say I could have decided otherwise?
Yeah.
And if you define yourself as the following list of atoms and particles in a certain configuration, then no.
Then the laws of physics said that that was going to happen.
But I don't know what all that is.
That's not a useful way of talking.
So there's a whole other way of talking that says I'm a person and I kind of like coffee but I already had a cup this morning and there's a chance, there's a probability like you say that I would drink this and a probability that I would not.
And those are completely compatible, although they're different.
The only way you get into trouble is if you mix up those two different ways of talking.
If you say, like, I chose to have the coffee because my atoms were in a following configuration or something like that, right?
That's like talking about us as humans and then switching vocabularies to talking about us as atoms, and that's where you get in trouble.
joe rogan
Yeah, it's a weird reductionist take on what it means to be a person that thinks.
sean carroll
Yeah.
Yeah.
I think, you know, if you say, like, there's no free will in your atoms, then I'm with you.
I'm on board.
But no one in the world goes through life that way.
joe rogan
Right.
sean carroll
For good reason.
And they never will.
It's not going to happen.
joe rogan
Yeah.
Well, and you could break that all the way down to creativity, right?
Like, when someone sits down and writes something, like, where's all that coming from?
unidentified
Right.
sean carroll
Yeah, so I think again, there is an interesting question about how much we will ultimately be able to unpack and understand about that, right?
Right now, the brain is kind of just a mystery box to us and there's so much we don't know about how people make decisions, how they remember things, how they come up with new ideas.
So where it matters is how we treat people, right?
The obvious case is responsibility, blame.
Like if you think that a person makes choices, then you can assign responsibility to them for making the choices they made.
That's what we do in the world.
If someone chooses to rob a bank, we choose to put them in jail, right?
And someone could come along and say – no one ever does this – but someone could come along and say, well, they're just a bunch of atoms obeying laws of physics.
How can you blame them, right?
That would be dopey.
That doesn't make any sense.
But what if – You were a minority report, right?
What if you could like put someone in an MRI in a brain scanner and say, yeah, you know what?
Tomorrow they're going to rob a bank.
Do you arrest them?
Is that enough, right?
The fact that their brain was hooked up to violate the law in the future, is that enough to assign personal responsibility to them for that?
Or do you do the opposite and say, well, it's going to happen no matter what.
We can't really blame them.
joe rogan
Well, and also if you do catch this thought process is before the actual action takes place, isn't it possible to correct that thought process with education or some sort of awareness training or something where you could shift the consciousness and abruptly isn't it possible to correct that thought process with education or some sort of awareness training or something where Yeah.
sean carroll
So there's a whole kind of interesting set of ideas that are very popular among philosophers right now, which is the question of moral luck.
So if you're driving down the street and you're buzzed, you're drunk, right?
Maybe you get home fine.
Maybe someone jumps in front of your car and you run them over because you don't have the agility or the reflexes because you're drunk, right?
So you're the same person.
You went home, you're drunk and you're driving home.
But depending on the outside world, you ran someone over and killed them or you didn't.
But in the world, we blame the person who ran somebody over.
We punish them much more severely than the person who got home safely, right?
That's not their responsibility.
They sort of got unlucky there in the world.
So should we blame people who had the chance of doing it?
No one knows the answer to these questions.
These are tricky things.
Like we're not very good, we human beings, at thinking about these probabilistic counterfactual questions.
joe rogan
Yeah, that's a good one.
That is, yeah.
Hmm.
Yeah.
Who are you then?
Are you lucky?
sean carroll
Oh, yeah.
Right.
I mean so much of what happens to us in life, we don't get responsibility for.
joe rogan
I mean we're interfacing with randomness every time we step out the door.
sean carroll
That's right.
But can you treat people that way consistently?
It's hard, right?
It's tricky.
I'm not giving the answer because I don't know.
joe rogan
There is no – right.
sean carroll
Yeah.
This is tricky stuff.
We're certainly not – like if you lived in a world where you thought that what happened in the world was preordained – That there was all the great playing out as a master plan or at the very least that there was some sort of karmic influence that made good things happen to good people, bad things happen to bad people.
Then the world makes more sense, right?
I don't believe any of that stuff but at least then the world seems – if there's something random, you can attach a reason why it happened.
joe rogan
There seems to be something to karma in that when you do good things, you make people feel better, they feel about you better, and then they interface with you in a more positive way, and that sort of like has this outgoing effect.
sean carroll
That's not karma.
That's just a psychologically smart thing to do.
unidentified
Right.
sean carroll
We – and maybe this is just sort of a Western post-Enlightenment way of thinking.
We tend to sort of think about immediate consequences for our actions for better or for worse.
And in the real world, sort of generally trying to be good can often pay back in good ways.
joe rogan
But the woo-woo thing – Is that we're putting out this good energy, and the good energy is coming back to us.
And it's a fun way to look at things, although there's no evidence that points to it.
sean carroll
Yeah, exactly.
Like, if I'm in a yoga class, and my yoga instructor is talking about different energy flowing through different chakras or whatever, I don't care.
Like, it doesn't bother me.
Like, as long as it makes me, you know, do that exercise in the right way.
There's a little.
There's a little, but I'm not going to speak up.
Let's put it that way.
joe rogan
Right, of course.
You're not going to go, stop this class.
You're teaching bullshit.
sean carroll
I would rather have that than, you know, if people want to come up with an excuse to be a good person, that's okay.
joe rogan
It's funny that yoga class is always the base.
It's always where people go to talk about where woo-woo comes from.
sean carroll
Yeah, yeah.
Yeah, it's – because I've had – I mean if you've done yoga, you know like there's a whole spectrum, right?
Like there's teachers who are basically just physical therapists and there are people who are complete crazy hippies who think that you have to think the right thoughts, you know.
joe rogan
Yeah, but people are always searching for some understanding of really complex issues.
And behavior is a very complex issue.
Behavior and how you feel.
Whether you feel good, whether you feel spiritually enriched, whether you feel positive about humanity.
We're always trying to manipulate these states, whether it's through meditation, mindfulness training.
Trying to figure out a way to positively interface.
sean carroll
You know, it's true and it goes back to where we started talking about YouTube comments because, like I said, I do react badly to stupid YouTube comments.
joe rogan
Well, you're a human being.
sean carroll
Well, I'm a human being, but I think that the internet does magnify some of our bad tendencies, right?
And I think that among these – and so I totally include myself as a bad actor here in the sense that it's just so easy to be sarcastic and put people down and disagree in sort of dismissive ways.
I don't think that's good.
I would like to live in a world where people including myself – Even when we disagree with people, even when we disagree with people who are stupid and we're not trying to engage them or improve their lives, just get on with our own lives rather than trying to have a snarky comeback.
Like I get that there's a purpose to snark and sarcasm and whatever.
But it weighs you down, right?
Like, you know, this is why people complain about Twitter and social media.
Like, it's so much psychic energy just gets sapped by reading all these complaints on either side.
There's no, you know, political bias, right?
Like, whatever your feelings are, someone else is making you feel down on the internet somewhere, and it does weigh on you.
joe rogan
There's also this weird impulse that people have with, whether it's Twitter or YouTube comments, this is reductionist take on things to reduce a person down to maybe one statement or misinterpretation of one position and then have that person be dismissed.
Whew!
sean carroll
Yeah, and I think it's tough.
After thinking about it a little bit, I think that it was a bad decision that James Gunn got fired, for example.
I don't know if you followed that little thing.
joe rogan
Guardians of the Galaxy guy.
Well, those were really bad tweets.
They just weren't funny, and he wrote a bunch of them, and there were a lot of it about pedophilia.
sean carroll
So I totally get it, right?
I'm not shocked that he got in trouble that way.
But I also think that his response was immediate and correct and grown up.
He said – he didn't say like, oh, I was young.
It was a different time.
He said like, oh, yeah, I did that.
It was shitty and it was wrong and I take responsibility.
And I do think we got to let people grow, right?
Like that's what most people in this sort of post-MeToo era have not done when they've been accused of these things.
They haven't taken responsibility.
They've made excuses.
And I think that on Twitter especially – I love Twitter.
I think it's my favorite social medium.
But it is too easy to be reductive.
It's too easy to be simplistic and to respond.
And one of the things that annoys me the most about Twitter is when someone tries to be good and then 20 other people say, well, you're not being good in precisely the right way.
I – even though I fail to live up to it myself, I'm trying to be better.
I want to be charitable when I deal with other people.
I got in trouble on Twitter the other day for defending Kellyanne Conway a little bit.
joe rogan
What did she do?
sean carroll
Well, years ago, she did the alternative facts thing.
Remember when she said – when they were talking about the inauguration?
unidentified
Right.
joe rogan
The size of the crowd.
sean carroll
And people pointed out like, no, that's just factually incorrect.
And she says, well, there are alternative facts.
unidentified
Right.
sean carroll
So like I don't want to defend Kellyanne Conway.
I'm not a defender of her in general.
But I think that she just misspoke that one time.
I think that what she was trying to say was there are additional facts that we could also look at, right?
And of course it's in a bigger context where she lies all the time and she lets other people – she is an apologist for other liars.
But I think that – The idea that these people who I disagree with politically are so divorced from reality that they think they can just make up their own reality, no one actually thinks that way.
Like the people who disagree with me about politics or religion or whatever, it's comforting for me to think that they are just – I'm going to disagree with you on that because I don't think that – first of all,
joe rogan
I don't think that she's granted any sort of autonomous decision-making capabilities.
And I think this is probably something that was sat down, that they sat down with a team of experts or, you know, air quote experts, team of people that were in that, you know, room, whether it's press people or...
Spin doctors, where they're trying to figure out a best way to get out of this, and one of the best ways was this concept of alternative facts.
Very similar to one of the ways where Trump was in that meeting with Putin, that very famous, awful meeting that happened recently, where he said, I don't see any reason why it would be Russia that's interfering.
And then he said afterwards, obviously, I misspoke.
I thought it was clear.
What I meant to say.
I didn't see any reason why it wouldn't be.
But it's clear if you watch him say it, that's not what he said.
sean carroll
That was entirely bullshit.
I agree.
joe rogan
Entirely bullshit.
Dangerous bullshit.
Scary bullshit, in my opinion.
sean carroll
Yes.
joe rogan
Because it's such a lie.
sean carroll
Right.
joe rogan
And it's so blatant.
The way he's expressing himself, it's clearly he's dismissing it.
Like, why would it be?
Why would it be Russia?
He's not saying, why wouldn't it be Russia?
Because he's standing right next to Putin, and he would be saying that in a much more measured, and he would be accusing Putin.
sean carroll
Yeah, that was clearly a case where he did something really bad and he came home and all of his advisors said, like, no, we have to fix this a little bit.
And they came up with a really clumsy, you know, incredibly— But that's all they had.
That's all they had, right, because it was so blatant.
joe rogan
And I think alternative facts is also all they had.
sean carroll
I don't – well, you might be right actually.
I didn't really study it very carefully.
I think that it was just a spontaneous blurting out.
joe rogan
You might be right too.
sean carroll
Because – here's why I think that that's probably right because I don't think – like I was trying to say before, I don't think that's their self-conception.
Like people often think that the people who they disagree with – I think that's very rare.
I think that happens.
Like if you're just a con man or whatever.
But I think that more often than we want to admit, people are sincere in their very false beliefs, right?
So I just find it implausible that – I mean Kellyanne Conway, again, lies all the time.
That is not my defense of her.
My defense of her is it was just that she would not go out there and say, "Oh, yes, but we're making up new facts." That's just not the kind of thing someone would say.
joe rogan
Trevor Burrus: But she didn't say it that way.
She said there are alternative facts.
Now you got to think that he's playing to the dumbest people in the room all the time.
And fortunately for him, that's a big number.
And there's a recent thing where he was defending his behavior, saying that anyone can act presidential.
And he stood on stage and he did this sort of robotic, boring walk back and forth, and then he started talking in a boring way and mocking it.
And what's interesting about the video is not just him doing this, which is very silly, but it's also the people behind him thinking it's hilarious.
sean carroll
I did not see this, yeah.
joe rogan
See if you can find it.
There's a video of him saying that anyone can act presidential.
This is very, very recently.
And a lot of people are watching this going, what?
sean carroll
He also thinks you need ID to buy groceries.
joe rogan
Yeah.
There's a lot of that.
Well, he also thinks that stealth bombers are invisible.
sean carroll
Yeah.
joe rogan
Did you see that?
They can't see them, right?
They can't see them?
sean carroll
They're invisible.
joe rogan
You're right behind it, asshole!
You can look at it.
sean carroll
Do you follow Kellyanne Conway's husband on Twitter?
Do you know about him?
joe rogan
I don't even know who he is.
sean carroll
George Conway, he's a lawyer, and he's very vocally anti-Trump.
It's hilarious.
unidentified
Really?
sean carroll
He's constantly subtweeting and making fun of Trump.
No kidding!
joe rogan
Oh, that's interesting.
Wow, that's gotta be fun.
That's a fun household.
But this is what gets me.
Go full screen in this.
You can't?
What's interesting is these dummies behind him.
Like, while this is happening, one of the interesting things about this, to me, is that his back is to all these people, which is very odd, right?
So, they're all behind him.
Instead of having a static backdrop, you're getting to...
Part of the thing is the other people.
It's not just him.
It's their reactions.
sean carroll
Yeah, it's a sense of belonging to a weird group.
joe rogan
Yeah.
sean carroll
And everyone has that, like leftists and rightists and whatever all have this weird belonging.
But when it's – again, it goes back to the China thing, right?
Well, we have Fox News.
We have a way of giving people information that if you follow – I follow Fox News on Twitter because I want to see – It's a weird thing because it's not like it's all lies, right?
There's often lies.
They're there.
But it's like a very different mixture of things than you would get from the rest of the media.
And a lot of it is...
It's very clear if you follow Fox News, like, they're targeting an older, white, rural, suburban audience, right?
So there's a lot of, like, weird human interest stories about an alligator popping out of the sewer and things like that.
Like, things that are not—they have no political agenda, but they're just trying to— Get those old white people to pay attention.
Yeah, well, they're sending a message that the world is kind of scary and weird and, you know, we need to protect ourselves.
joe rogan
There's an alligator on the golf course.
sean carroll
They really—yeah, like, they love those stories, right?
Yeah.
joe rogan
The alligator of the golf course is my favorite.
sean carroll
It's just local news.
It's the 10 o'clock local news put nationwide and added in there with some cheerleading for this bizarrely dysfunctional administration.
joe rogan
Well, isn't Sean Hannity now the number one watch cable news program?
sean carroll
Something like that.
Yeah, I don't know the numbers.
joe rogan
I think it's number one, and it's fucking awful.
sean carroll
They just...
There was just a poll.
This goes back to the social credit thing.
They did a poll.
What is the most trusted news source?
And Fox News came in number two.
joe rogan
What's number one?
BBC. That makes sense.
Well, CNN has just taken a giant hit because of his constant, constant berating of them.
And then you see Jim Acosta, all these pro wrestling fans giving him the finger and screaming at him.
sean carroll
It's like, what?
unidentified
Yeah.
sean carroll
I do worry that this is a hard thing to come back from because, you know, once you – another thing that Trump said was that, you know, don't believe anything you're told, right?
Unless you hear it from me.
And Sean Hannity says the same thing.
No, I was – sorry, Tucker Carlson said the same thing, right?
joe rogan
Did he say that too?
sean carroll
Tucker Carlson said like, yeah, any other show than this one, don't believe it.
joe rogan
Yeah, look at this.
Fuck the media he has on.
Women for Trump.
Yeah, it's just – what?
And then after listening to this Radiolab podcast about these Russian troll farms and about how they implement these things, you've got to think, is all of this organic?
How much of this is orchestrated?
How much of this attacking CNN is orchestrated?
sean carroll
Part of it is.
Part of it is.
It builds on itself.
joe rogan
All you need is just a little bit of a push.
sean carroll
I was talking to someone who is boasting about how hard Donald Trump works.
That, like, compared to previous presidents, he's really just putting in the hours.
joe rogan
Oh, that's not true, right?
sean carroll
Which is, like, really the least possible thing that you could think about.
joe rogan
Yeah, he wakes up late, he watches eight hours of TV a day.
sean carroll
Yeah, he watches TV, plays golf every day.
He, like, spends all the time at his own resorts.
Like, of all the fantasies you could invent, that's a very weird one.
joe rogan
Well, people just love to find narratives that fit what would be, you know, acceptable for their opinions, this side that they've taken.
sean carroll
Exactly.
Right.
Yeah.
And so, you know, give them credit.
He gives people a narrative that works for them.
joe rogan
Well, CNN does it, too, because CNN, they spent so little time going over Donna Brazile's book.
About how the DNC had been corrupted and about how they had rigged the primaries for Hillary and really screwed Bernie Sanders over.
This was not a narrative that they dwelled on.
They didn't dwell on the fact that she illegally deleted 30 plus thousand emails and said they were about yoga classes.
That shit is just as preposterous.
It's just as damning against CNN as some of the nonsense that Fox News does.
There's no one pure organization of news that's wholly objective.
sean carroll
It's not just as damning.
I think that Fox News is special.
I really do.
joe rogan
Especially damning.
sean carroll
I think that Fox – I mean Fox News was founded by a guy who was a political operator for the Republican Party, right?
Like there might – like individual reporters from most news organizations tend to be liberal.
But they also sometimes tend to overcorrect for that, like to try to bend over backwards to be fair.
Like way more Republicans are quoted in The New York Times than Democrats ever are.
And I think that there are certainly biases and certainly misrepresentations of reality from all these different outlets.
But I think Fox News is special among the major ones.
joe rogan
I would concede that.
But I also think that one example, like the New York Times is different because – The New York Times, I feel like because of the fact that it's actually writers and it's in text, you're not dealing with people that have to be comfortable performing in front of a camera, which eliminates a large swath of intellectuals.
sean carroll
Right.
It's a different medium.
And they fact check and, you know, corrections in a way that the TV does not.
joe rogan
Yeah, it's theater.
It's a different thing.
And people like Sean Hannity, that if you read his written word, I don't think he would stand out.
sean carroll
No, and again, like I said before, I worry about what happens next because I don't think that Trump will win again.
joe rogan
I think he will.
sean carroll
All right.
I don't think so.
joe rogan
I think it's entirely possible he'll win again.
sean carroll
Yeah, but again, I didn't think he was going to win the first time.
No, I didn't.
I was just going to say, don't listen to me.
Before Donald Trump, I was really good at predicting who was going to win elections.
I have no ability once he's in the game.
But I worry that the people who sort of are on his side are going to feel even more disenfranchised and disenchanted and angry.
joe rogan
I think that one of the reasons why I said it's entirely possible, and I don't know if he will win again, but I don't even know if I believe he'll win again, but I think it's a possibility.
And I think that one of the reasons why I think that is I don't see who's the big candidate on the other side that's opposing him that stands out right now.
sean carroll
Yeah, that's a problem.
joe rogan
I think there's a real issue with people not wanting the job.
It's a really scary job, you know?
I mean, it sucks you dry like a vampire that's hooked up to the back of your neck.
It's just so, even with him, with his unique ability to sociopathically sort of navigate the waters of accusations and guilt, he still looks beaten down by this job.
sean carroll
Yeah, but people want it.
Maybe not the people we want to want it, right?
joe rogan
Who wants it on the Democrat side?
Who wants it on the left that stands out?
sean carroll
I mean, I think...
I'm not excited by any of the people right now, but I think...
joe rogan
No one is.
sean carroll
I bet there's going to be 10 people running at least.
I mean, I think that Biden has at least 50% chance to run.
Elizabeth Warren's definitely going to run.
joe rogan
Do you think Elizabeth Warren, though, she's got that real problem with the whole Pocahontas thing.
That whole Indian thing.
sean carroll
Whether you're going to run is different than whether you're going to win.
joe rogan
Right.
But that is a giant problem.
The thing that she may have faked, whether or not she has Native American heritage and she's not willing to take a DNA test.
And this Native American heritage, she claimed, is how she got into Harvard.
And she used that in order to get special status, and that's a problem.
You know, whether or not you should forgive someone for something they did a long, long time ago, which I think you probably should.
The problem is, it sort of, in some ways, negates a lot of the good work and things that she said, because people say, I can't trust her.
She lied about her actual ethnicity.
sean carroll
Yeah, it's – but what is hard for me to do is to predict how much it will matter, right?
Like in 2008, we had a race between a Vietnam War hero and a black guy whose middle name was Hussein.
If you had told me that a few years earlier, who's going to win?
I would have gotten that one wrong.
joe rogan
We also had Sarah Palin.
Yeah, exactly.
sean carroll
This is what we don't know.
joe rogan
If he had taken a better running mate, it's entirely possible McCain would have been president.
sean carroll
I think that people were really tired of George W. And I think that McCain was just not a good candidate.
joe rogan
I think he was going to lose no matter what.
Obama was so charismatic and so uniquely intelligent and smooth and relaxed and statesmanlike.
I think he fit the bill of what we wanted a president to be.
sean carroll
But remember, people were worried about like he went to Jeremiah Wright's church and things like that, right?
Right.
Stuff that didn't – like at the time, it was a big deal and who cares eight years later, right?
So I don't know about the Pocahontas stuff.
joe rogan
That's a big one though.
The Pocahontas stuff is a big one because it's a personal lie.
sean carroll
I don't know.
But again, I mean, I think Cory Booker is going to run.
Kamala Harris might run.
Who knows?
There's a bunch of people.
I would not be at all surprised if Joe Biden didn't run.
I'm kind of Don't think that he should, but he's getting up there.
And he's a Washington insider, which is not really what the country wants, right?
joe rogan
In 1988, in Boston, we used to have Joe Biden night at the comedy clubs.
And Joe Biden night was a night where we would do other people's material.
Because this is when Joe Biden got busted with Kennedy speeches.
sean carroll
Yeah, well, and Neil Kinnick, the British politician, stole from him too.
joe rogan
And this was when he was running for president in 88. Right.
sean carroll
He's never done very well running for president.
He's run several times.
So I think that he was a good vice president, and people like him for that, and they might not want him to do more than that.
joe rogan
Vice president is a great job if you want no one to pay attention to you.
sean carroll
Yeah, exactly.
joe rogan
It's like being the co-star in a buddy cop movie with a huge superstar.
sean carroll
Very few responsibilities, go to some funerals.
joe rogan
Yeah, easy.
sean carroll
Yeah, unless you're Mike Pence where you're trying to make it The Handmaid's Tale behind the scenes.
joe rogan
He seems like he's kind of laying back though, especially over the last few months.
Trump is so insane that you see very little Mike Pence.
sean carroll
I don't think you see very little of him, but I think that he's trying his best to put in policies behind the scenes.
joe rogan
Well, what is this new thing that Jeff Sessions is trying to push?
sean carroll
Religious freedom.
joe rogan
Yes.
sean carroll
Which means you have to obey whatever the fundamentalist Christians want to do.
Yeah.
joe rogan
Well, this is what – Michael Malice was tweeting about this the other day when he tweeted this.
He said, when I said that a version of Sharia law could very well be coming out of this administration, this is what I'm talking about.
sean carroll
Yeah.
Yeah, it's a weird backward thing where you define religious freedom to be let fundamentalist Christians do whatever they want, right?
joe rogan
Yeah, and do it by law.
sean carroll
Yeah, yeah.
I mean it's tricky because – Yeah, I don't know.
I mean if someone wants – part of me is a little bit libertarian when it comes to personal action.
Like if someone doesn't want to deal with you, that's their right.
But when whole groups are being subject systematically to discrimination like gays are, then the government steps in to protect them a little bit and I think that's OK. And a lot of this is doctors don't want to do abortions or health care providers or insurance providers don't want to pay for things because of their religious beliefs or Catholic universities don't want to do certain things and – I think that these are legitimate questions and we're not really having a grown-up intellectual conversation about them.
We're just throwing feces at each other in this particular arena.
joe rogan
Well, it's also strange when someone comes up with some sort of a new idea like that, that goes against the separation of church and state.
And it's being promoted by a guy who's openly religious and says a bunch of really preposterous things.
And, you know, generally someone who's not a very trustworthy source of...
Well, that's right.
sean carroll
And there's this fascinating question about why white evangelicals are Trump's biggest support group, right?
Like huge – despite the fact that he is not religious himself, that he's the biggest sinner ever to be in the Oval Office.
But they love him.
And it's a weird thing.
And I think a lot of it comes – well, so there's sort of the – Strategic questions, a lot of it comes down to abortion, right?
They want Supreme Court justices who will overturn Roe v.
unidentified
Wade.
sean carroll
And whoever – however they're going to get that is good for them.
But then there's a whole much more elaborate apologetics about how God is using Donald Trump as his instrument to make the country better even if he himself is a flawed vessel.
Sometimes God works through flawed vessels.
joe rogan
Well, if you position yourself as an ally, even if you have previously sinned, the beautiful thing about Christianity is all you have to do is say, that's not me anymore, I found Jesus.
And I saw a pastor on television going on about that, and about, when you're talking about Trump, you're talking about the Trump before he found Jesus.
And he's like, I don't have a past.
And he's like, I am born again.
I do not have a past.
Do you?
And he was going on about this whole thing about this concept of Trump is now an agent of God.
sean carroll
But I don't necessarily even think it's Christianity.
I think that religion can be infinitely malleable to the purposes of the moment, right?
Sure.
He wouldn't have said that about Obama or whoever, right?
You pick and choose when you apply your criteria.
Like I did this once as an exercise for myself.
There are certain phrases in the Bible or certain passages in the Bible which are sort of unapologetically Right.
And just like there are others that are unapologetically right-wing and authoritarian, it's a big book full of different things.
So I wondered like how – what do they tell themselves?
What do the people who don't fall on that side of the spectrum tell themselves about these passages in the Bible?
So there's one very famous passage about how it is easier for a camel to pass through the eye of a needle than for a rich man to enter the kingdom of heaven, right?
Clearly, I think that anyone who reads this says this is an anti-rich person.
So you can Google it.
So what do people say about this?
So my favorite explanation was that sure, it's impossible for camels to pass through the eyes of a needle except if Jesus helps them.
joe rogan
Or if you grind the camel down to very fine dust and one particle at a time.
sean carroll
They interpret this as that only through Jesus do we get into heaven.
That's really the only lesson they get from heaven.
joe rogan
Oh, okay.
So that's nice.
sean carroll
It has nothing to do with rich people.
joe rogan
All you have to do is find Jesus, and if you're rich, you're good.
But on your own, you're fucked.
sean carroll
This is why I can't – even though I'm an atheist, I'm very happy to explain why I don't think that God exists.
But I don't blame religion most of the time for people's bad actions because I think that religion is just sort of a catalyst.
It lets people find excuses for their bad actions.
But it's usually the bad actions, the desire to do bad actions that comes first most of the time.
Do you ever look at religion as a potential almost evolutionary software program that's allowed people to – I think we are a little bit quick to attribute ideas and cultural concepts to evolution.
But certainly, you know, religion was not like just science done badly back in the day, right?
Like what religion was was something much more expansive, interleaved with your life overall.
So it was not just how the world was created and whether God exists.
how to be a good person, how to live in your community, things like that.
And disentangling these things is one of the reasons why religion is still hanging around, right?
Like even after the kind of underpinnings of the religion in terms of understanding how the world works have been removed by science, the other thing is that religion is still The other functions are still there and I'm a big critic of my fellow naturalists who have not put enough effort into replacing the other functions of religion now that the claims about the world are no longer viable.
joe rogan
Aaron Ross Powell That's a great way to present it.
Yeah, and it's really a problem when there's so many versions.
sean carroll
Yeah.
So I mean one of the many, many reasons why I think that it's not really credible to be religious intellectually is because if – in the classic traditional Western religious sense where there's a god and he cares about us, right?
So there's all sorts of questions about where we define the boundary of religion, whether Buddhism is a religion or something like that.
But in the usual sense that we grew up with in this country – Aaron Ross Powell Surely, if that were true, God would have done a much better job of explaining himself to us, right?
Like, why would God give us his message through a bunch of people in a tiny country who didn't write?
You know, like, the New Testament wasn't written down until decades after the event.
None of the people who wrote it down were eyewitnesses.
Why is it only shared there?
I mean, God is God, right?
Like, he could easily have showed up to everybody in the world, talk to them, explain how things were going, and let them make their own choices.
That would have been a much more efficient way of getting the message out.
And so it's just not really sensible to think that – so if God didn't exist, then what you would imagine is that in different countries and different parts of the world and different periods in history, people would tell their own stories and they'd all be a little bit different and they'd be adapted to their local circumstances and they'd be utterly incompatible with each other.
And that's exactly what you find.
joe rogan
Do you speculate as to what the origins of the concept of God are since so many different groups of people all over the world have a very similar idea, at least, that there's some omnipotent superpower that's controlling the destiny of everything?
sean carroll
Yeah.
So number one, I think that the idea of omnipotence was actually somewhat late coming onto the scene, right?
Like if you dig into what was happening before 2,000 years ago, you know, the Hebrew God was not omnipotent at the beginning, right?
The Hebrews came out of a polytheistic society where there were lots of different gods around and you can trace how their god evolved over time and first became their god, right?
Like this was one god that the Hebrews were worshipping and the Egyptians and the Babylonians would worship other gods.
Then they started saying, well, our god is better than all the other ones.
And then they started saying, well, the other ones don't even exist, right?
And it was an evolution over time and omnipotence came late.
Like you would talk about the gods quarreling.
If you were a polytheistic, a pagan culture, it actually makes more – like a lot of the world makes more sense if you believe there's a whole bunch of gods out there who disagree with each other, right?
Suddenly lots of aspects of reality come into focus.
But the idea there's supernatural, very powerful – I mean that's just an obvious idea I think.
Like we're human beings.
We tend to – as our first guess in understanding the world, treat the world as humanists.
Like we're anthropomorphic, right?
Like if something exists, it must have been designed.
There must be a reason.
There must be a purpose.
Things work in a certain way because someone made them that way.
We don't see that person hanging around so it must be up there in the sky or something.
I don't think it's that hard to imagine that all sorts of different cultures would evolve.
joe rogan
Trevor Burrus Do you think it's also a function of us growing up with mentors and father figures and leaders and chieftains and there's always someone who is the big kahuna.
So this is the sky daddy.
Sky daddy overlooks the big picture.
sean carroll
I think there's that and also the idea of your ancestors and ancestor worship or veneration, right, which is also very – almost universal in primitive cultures.
Like you don't want to admit you died, right?
That's a sad thing to sit through.
So I don't know.
I'm sure there are real experts who know a lot about the actual origins of these things.
But my point is just that I don't take the commonalities between different sets of religious beliefs as evidence for anything other than this is a very human thing to invent.
joe rogan
People search for meaning and they take meaning from whatever religion or ideology that they subscribe to and they use it as sort of a A reason why they're living.
It gives them hope.
It gives them something.
unidentified
Yeah.
sean carroll
It's a very common theme among religious thinkers that if it weren't for the existence of God or whatever, there'd be no reason to live.
There'd be no reason to be a good person and so forth.
And, you know, I think it goes back to the motivation we have as having bodies versus being in a computer.
Like there's plenty of reasons to do different things.
Like in the big picture in my last book, I talk a lot about – it's OK to admit that we as human beings have desires, that there are things we care about, that we want to be true.
And you can talk about why that's true from evolution, from biology and whatever.
But it doesn't matter why in some sense.
We have goals.
We're not completely aimless.
Like we want to survive.
We want to flourish.
We want to be friends with people.
We want to have families, whatever it is we want to do.
All that we put together in terms of morality and ethics and meaning and purpose comes out of thinking hard and carefully, hopefully, about how to systematize and grow those existing desires that we have into a way of living in the world.
We don't need anything external to make that happen.
We just need to sort of think about where we are already and try to make it better.
joe rogan
But you as an intelligent person who's also an atheist, who thinks very deeply about things, what do you cling to as a purpose for life?
Do you have one?
Do you have like a...
When you sit and think, what's the point of all this?
Do you...
Do you?
sean carroll
I don't have a single one.
I don't have a monolithic purpose.
I have plenty of intermediate-sized purposes, right?
Otherwise, why continue living?
I think that there's plenty of things I want to do, to achieve, to experience, to share, to give to the world, right?
joe rogan
That's a big feature, right?
The give to the world.
Absolutely.
The way you interact with other human beings and your effect on other human beings, Trevor Burrus Yeah.
sean carroll
And even if I think that when I die, I will no longer exist and my feelings won't matter, I have feelings right now about what the world will be like even after I'm not here anymore, right?
So I can still be motivated to make the world a better place in ways that will outlive me, even if I think that when I die, it's really the end for me.
joe rogan
Trevor Burrus Do you get down sometimes?
Do you ever – do you get like these periods of like – what is the purpose of all this?
sean carroll
Especially if you see some ridiculous thing in the news or some horrific tragedy and … For horrific tragedies, no.
I'm just fortunate enough to be pretty even-keeled when it comes to that stuff.
I don't struggle with depression or despair or existential anxiety or anything like that.
When I was a kid, when I was first starting to think about the universe and science and things like that, I would start wondering about, well, what if the universe hadn't existed at all?
What if I – It wasn't here.
And that made me lose sleep that night.
And I think like many people, there was a very definite moment when I realized that I and everyone I knew would die, right?
So I woke up crying and my mom had to comfort me because I was like, you know, grandmom's going to die and you're going to die and I'm going to die.
But as a grown-up, no, I think that I'm more or less – So again, one of the future podcast guests that I'll be – next week's podcast will be by a woman who's part of the death positive movement.
Have you heard about this?
joe rogan
No.
sean carroll
Yeah.
This is real stuff.
joe rogan
What?
Who?
sean carroll
So don't distinguish – don't confuse it.
There is a whole movement like an antinatalist move or something like that.
I forget what they call themselves.
But there's a whole movement that wants human beings not to exist.
That's crazy.
joe rogan
Yeah.
sean carroll
But there are people who like that.
The death positive movement is the following.
Like we're going to die.
We should face up to it.
We should accept it and we should deal with it in a personally and culturally positive way.
So for example, like right now, especially in the United States, even compared to Europe or other countries, We're terrible at dealing with death.
We put people in hospitals.
We take them away from their families, away from their homes.
We refuse to admit that they're going to die.
So we treat it as if the whole purpose of the game is to squeeze out as many more hours of life as possible no matter what the quality of that life is.
And all that is just rubbish and we should be much more grown up about it.
We should plan ahead.
When Obama suggested that in the healthcare system there should be some planning for what happens when you die, Sarah Palin came along with death panels.
That was a very effective rhetorical strategy.
We don't want to think.
die.
We don't want to plan for it.
If we did plan for it, it could be better.
We could die at home.
We could die with less pain.
We might not live as long as we don't like do every single medical intervention possible just to squeeze out a few more breaths.
But it could be a much more life-affirming experience to die because the people around us who are there come across with an acceptance of what's going on rather than the feeling that we should just do everything we can to prevent it?
joe rogan
I had a similar situation happen recently with a dog of mine who's a Mastiff who reached 13 years old.
And for Mastiffs, that's very old.
And we had to put him down because he couldn't walk anymore.
And he was...
It was brutally painful to watch him try to get up and fall down.
But one of the things I was thinking was that if this was my grandfather and not my dog, Yeah.
again.
unidentified
Right.
joe rogan
And knew his days were numbered.
He couldn't do anything.
Most days he just slept all day until it was time to eat.
But it was getting to the point where I had to carry him to his food.
sean carroll
Yeah.
joe rogan
And I knew that it was rolling.
sean carroll
There's no quality of life, right?
joe rogan
There's no quality of life.
sean carroll
In some sense, it's even harder with the dog because you can't talk to them, right?
You can't explain to them what's going on.
They can't explain to you what their wishes are.
So you have to be the responsible one.
But yeah, so everything legally and culturally in the United States is we're not allowed to relieve that pain or that despair that you have near the end of your life.
Some states, including California, are passing death with dignity laws where basically it's what used to be called assisted suicide, but we don't call it that anymore.
A doctor is allowed to give you the means to end your own life when you're near.
You have to be near a point of no return but still clearly thinking enough to be able to make that decision for yourself.
joe rogan
And there's also an issue with our real concern is their fear and this experience being this terrifying sort of step into the great beyond.
There's a tool to mitigate that and the tool that has been shown to mitigate that is psychedelics.
One of the big ones being psilocybin.
Psilocybin has a remarkable effect on people that are going through stage 4 cancer.
Johns Hopkins has studied it.
There's quite a few studies that have shown that people, when you give them psilocybin, they're much more relaxed and much more comfortable with this idea of ending this life.
It's gone through its course, and it's an inevitable thing, and it's really our biological limitations that are terrified and sparking up all these things.
sean carroll
Yeah, I'm actually 100% in agreement there.
My wife, Jennifer Ouellette, who is a science writer, wrote a book called Me, Myself and Why, Searching for the Science of Self.
And one of our friends said, oh, if you're going to write a book about the self, you got to do LSD. And so we did, and she researched it, and it's a fascinating history, right?
And Aldous Huxley, I don't know if you know about Aldous Huxley's story, and he took LSD to do exactly this.
He had throat cancer, and it completely helped.
Yeah, it's never fun to die, right?
It absolutely helped ease that journey in a very simple way.
But just as we are a sort of immature society that doesn't want to face up to the reality of our eventual deaths, we're also very culturally conservative and squeamish about drugs, right?
And so we don't even let people do research on some of these drugs.
And so I think that, yeah, we have a lot of growing up to do when it comes to not just living a good life but also having a good death.
joe rogan
And also paying attention to actual scientists who have studied these compounds and really understand what the effects of them are and have researched them deeply and have personal experiences with them and are saying, well, these things have been demonized.
And they're tools that we can use to sort of mitigate a lot of the real issues that we have.
Whether it's culturally or personally with these transitionary times, like death is inevitable.
So now that we know it's inevitable, you tell me what the main problem would be with someone taking psilocybin before they die and letting them ease their way through this.
sean carroll
But you know, it's the same reaction that doesn't want people to have a basic income.
Right?
There is a sort of moral feeling that you're weak if you don't struggle against death, everything, and it's silly, right?
It makes no sense, but it's very, very common.
joe rogan
Yeah, it's so weird that the universal basic income topic is one of those knee-jerk reactionary topics that I myself, my friend Eddie Huang, Introduced it to me for the first time.
And my initial knee-jerk reaction was, oh, you can't do that to people.
Human nature, people are going to get lazy.
And then the more I thought about it, I was like, well, if you just cover their food and their rent, is it really going to kill their ambition?
Is our ambition uniquely tied to just survival?
That doesn't make any sense.
sean carroll
Well, and it's a weird – it's the same weird thing that people use against having a progressive tax system.
Like if we have – if we tax people's money, they won't want to work anymore.
But if – you still want more money.
Like we don't tax them so much that you have less money the harder you work.
That's not how it works.
And I think like what – so – but also for the universal basic income stuff, I think people have to reconcile themselves.
So what if someone wants to just sit around and play video games all day?
Is that the worst thing in the world?
I mean I think that there will be people like that.
There will still be other people who want to write poetry and build sailboats and build spacecraft, et cetera, or build artificial intelligence.
I mean it wouldn't – what if everyone could do whatever they want when they were kids, when they were 10 years old.
They were taught a good programming language and could make up whatever apps and programs they wanted.
Like that would be a whole different world than what we live in right now and it might be very exciting.
joe rogan
Well, creatively, it could possibly expand a lot of people's potentials, right, where they no longer have to have a job so they could do whatever this one thing is that they're thinking about doing, write a book, a screenplay, develop something.
sean carroll
And in the short term, I don't know if a basic income works sort of economically, but I think that if we believe that there's more and more stuff that can be done by computers or by robots or whatever, automation, Then it's absolutely something that should be taken seriously.
Yeah.
So I think that the whole theme, this is great because we've been talking in a lot of different angles about the fact that the shape of the world is changing in a way that makes what it means to be human changing.
And facing up to what those changes are, the fact that we die, the fact that we make up purpose and meaning for ourselves and our lives, and the fact that – What we are physically in terms of bodies and machines and so forth is also changing.
So part of the theme of my podcast, I hope, is that to think through some of these issues to sort of – I don't know the answers, but I want to ask the questions about who we are, what we're living, what should we be doing about it because God's not going to give us the answer.
joe rogan
Well, I think podcasts like yours and, I mean, any podcast where people are really Carefully considering issues.
I think what's important about them that really didn't exist before is that someone can sort of digest these very complex subjects through two people having a conversation about it that perhaps are more informed and have more data and have more thought about these particular issues.
So what you can do and what Sam Harris can do and a lot of people can do that are creating these podcasts about these really complex issues is you start that conversation and this seed gets planted into someone's head and maybe they carry with them at work, they carry with them when they're on the subway or during their commute home and then they become a part of the broader conversation that we have as a culture.
sean carroll
Exactly, yeah.
And that's why I sort of want to not draw a distinction between science and other ways of thinking deeply about the world because I want people to – I've often said this as a joke.
I want to live in a world where people work hard in the factory and they go out for a drink afterward and talk about their favorite interpretation of quantum mechanics, right?
I want that to be the kind of thing people are bullshitting about over beers.
That would be a world I want to live in.
joe rogan
Is that possible?
Have you ever run into a quantum mechanics conversation at a bar?
sean carroll
There are far too many people who think they understand something about quantum mechanics and are going to explain it to me.
So I want the existing conversations to be a little bit more informed.
joe rogan
Well, there's a few people online that someone has – you've got to get this guy on.
And then I've listened to them talk and I'm like, I'm pretty sure – That that guy's full of shit, but I can't really point out how I know that.
sean carroll
A lot of crack bots.
Feel free to email me.
I will help you out.
joe rogan
Well, I don't want to bring this one guy up, but I'll talk to you about it off the air.
sean carroll
There's a lot of woo-woo out there, but also it's quantum mechanics.
A lot of very respectable people who sound crazy if you don't know too deeply what they're saying.
joe rogan
Well, that is the Feynman quote, right?
If you think you know quantum mechanics, you definitely don't know quantum mechanics?
sean carroll
Exactly, which is – the whole point of my book is to overcome that feeling because I think what happened is it's true that we don't agree.
We physicists don't agree on what quantum mechanics says.
Yeah.
If you try to understand it too hard, you're wasting your time.
And I so disagree with that point of view.
So I think that quantum mechanics is and should be understandable by everybody.
unidentified
What a squirrely concept. - It's, It's – yeah.
sean carroll
Yeah, it's weird and that's why a lot of people – there's a lot of people who I know who are friends of mine who are professors in philosophy departments because they got a PhD in physics and they realized what they really wanted to do was to think about quantum mechanics in a deep way and they would never get a job in a physics department doing that.
But philosophy would let them do it.
joe rogan
Oh, wow.
Interesting.
sean carroll
What they're really doing is physics, but they're doing it in a way that philosophers are happy with and physicists aren't.
joe rogan
What year did the concept of quantum mechanics become invented and discussed?
sean carroll
It started in 1900, exactly.
But they sort of perfected the modern version around 1927. What was the original thought process?
joe rogan
Do you know?
sean carroll
Yeah.
It's – the history is amazing and messy because they didn't – there was so much weirdness going on.
It was Max Planck, right, of Planck radiation.
Have you ever heard of that?
No.
German physicist.
So black body radiation.
Something glows when you heat it up, right?
Right.
So basically what happens when you heat something up is all the atoms and molecules start vibrating.
There's a lot of charged particles.
A charged particle has an electric field around it.
And if you vibrate it, the electric field starts vibrating.
We call that light or radiation, right?
Electromagnetic waves are being emitted.
So you could – in the year 1900, you could sit down and do a calculation.
What should that look like?
If you heat everything up, how much radiation should it give off?
And the problem was it should give off an infinite amount of radiation at very long wavelengths, which is obviously false, right?
It's obviously not how things really work.
So there was this blatant disagreement between everything we thought we knew because in the 19th century, in the 1800s, people really thought in physics that they were close to the answer, right?
They had a picture where there were particles like electrons and protons and then there were fields like the electromagnetic field and the gravitational field and the particles were matter and the fields pushed them together.
They interacted.
They were the forces, right?
And this picture was so good and so compelling that people were basically like, we're almost done with physics, right?
We almost have it all figured out.
And then there were a couple of little things like the blackbody radiation that you made a prediction.
It was wildly off.
And so they're like, well, what's going to happen?
So Planck says, well, maybe when this electromagnetic radiation is emitted, it's not just a continual stream of radiation.
Maybe it's like individual little packets of energy.
He had no reason to say that.
Like, he's just out of the blue.
It was just pulled out of his butt, right?
joe rogan
So he was just sitting there with a pad, just contemplating.
sean carroll
And he's like, what if?
And he goes, what if?
He gets exactly the right answer.
It fits the data, right?
And he said, there it is.
And he himself, like, wasn't sure what to make of this.
He's like, I got this idea.
It gives the right answer.
Who knows?
joe rogan
That is crazy.
sean carroll
And it was five years later.
A young man named Albert Einstein said, well, I know what's going on.
Those little packets of energy are themselves particles, that light is not a wave.
There's particles that are being given off, photons, what they were later called, right?
And that's what he won the Nobel Prize for.
Einstein never won a Nobel Prize for relativity.
He won the Nobel Prize for inventing photons, basically.
Trevor Burrus And then – so there was that – so that was – there were two tracks going on.
Remember I just said in the 19th century it was – the world is made of particles and fields.
So the first thing that happened is people started thinking about these fields, the electromagnetic field and Einstein says, well, there's something a little bit particle-like about it, right?
It's not a hard and firm distinction.
Then separately, they looked at atoms, right?
So you have an electron orbiting an atom, orbiting the nucleus of an atom.
You have this picture that everyone has seen of a cartoon of an atom, right, with the electron orbiting around.
Again, you can make a prediction that that electron moving around the nucleus of an atom should be giving off light.
It's a moving electron.
When you accelerate an electron, it gives off light.
So it should lose energy and spiral into the middle.
It should not just stay in the same orbit.
It should be losing energy by radiating energy away.
You can calculate for a typical atom how long should it take before the atom shrinks to zero size.
And the answer is like a hundred billionth of a second.
So all the atoms that you and I are made of should just go right away.
joe rogan
Evaporate.
sean carroll
Yeah, evaporate.
Give off light and scrunch down to zero size.
That's a problem, right?
That's not compatible with the data.
So Niels Bohr in 1913-ish comes along and says, I have an idea.
What if the electrons don't do that because they can't?
What if there's certain orbits that they're allowed to have and they're not allowed to have any other ones?
Again, just pulled out of nowhere, like for no good reason.
But he says, if that's true, I predict the following spectrum of radiation from hydrogen.
Look it up.
It's exactly right.
It fits the data perfectly.
And people are like, what the hell is going on?
And then it was – so that took like another 10, 15 years before people like Heisenberg and Schrodinger built that up into saying it's not just – That waves of light have a certain particle-ness.
It's also that particles like electrons have a certain waviness and there's a wave function and they're inventing quantum mechanics and we're still arguing about it to this day.
joe rogan
Well, it's such a difficult concept to Wrap your head around that it's been distorted, right?
Especially by the Woo merchants.
sean carroll
I have a fun part in my book.
I list like 20 titles that came up in Amazon when you type the word quantum in.
So there's like quantum love, quantum power, quantum yoga, quantum healing, quantum politics, quantum theology.
It's like used for every crazy bit of nonsense that you've ever heard of.
joe rogan
How do you mitigate that?
sean carroll
Write more books, have more podcasts, keep talking, right?
Like, you know, you'll never get rid of it entirely.
There, you know, as you may have heard, there are people who still believe the earth is flat.
joe rogan
Oh, I have heard.
sean carroll
So you're never going to completely get rid of the wrong ideas, but you can get the right ideas out there more effectively.
joe rogan
Yeah.
Do you think that it's possible that, I mean, this concept was created and invented somewhere around the 1900s?
Is it possible that another theory that's just as revolutionary is being developed right now?
And through things like the Large Hadron Collider and It's search for understanding the elementary particles of the universe.
Is it possible that we could develop a new theory and are there any that are being contemplated right now?
sean carroll
So it's absolutely possible.
That was what Einstein tried his best to do, right?
He thought that he could do better than quantum mechanics and he did not succeed.
The big difference is that when real quantum mechanics was developed between 1900 and 1927, at every step it was because there was some dramatic disagreement between the theory and the data.
And right now, our theories are good enough that they fit the data really, really well.
So we're trying to make – I and others are proposing new ideas to try to understand how space-time emerges in quantum mechanics and things like that.
And you can try to do better than quantum mechanics.
But it's all just on pure principle, right?
On pure coherence and beauty and elegance because we have a theory that fits the data fine.
And it's so much harder to make progress when you're just trying to do it in your brain rather than doing it by data.
joe rogan
So as for right now, there's nothing else being contemplated.
sean carroll
That's pretty unique.
It is being contemplated, nothing promising, nothing emergent.
Like there are people who think they can do better.
There is no one who agrees that someone else is doing better right now.
joe rogan
Are there any standout theories that people have sort of?
sean carroll
I think replacing quantum mechanics or even improving quantum mechanics is because there's no guidance whatsoever from experiments.
There's not even a sort of leading thing.
In fact, I don't think it's the right way to go.
I think that given right now, given the fact that we have quantum mechanics and yet don't quite understand it, our job should be to understand what we got.
joe rogan
What has come out of the Large Hadron Collider?
I know that there was some discussion as to whether or not they found the Higgs.
Is it Boson or Bosson?
sean carroll
I say Boson, but...
It's pronounced with a Z, but it's spelled with an S. B-O-S-O-N. Oh, it is pronounced – because I only read it.
I never – Yeah, physicists say boson.
joe rogan
Boson?
sean carroll
Yeah.
joe rogan
Okay, so the Higgs boson.
There was some discussion that they had absolutely proven its existence, but then there was also some debate about that.
sean carroll
So it's actually a very bittersweet story, the Large Hadron Collider.
joe rogan
Damn it.
sean carroll
I hate a bittersweet story.
Well, life doesn't promise you a rose garden.
We found the Higgs boson fairly quickly after getting the Large Hadron Collider up to speed.
We found it in 2012. You can read that in my other book, The Particle at the End of the Universe.
But we didn't find anything else.
So did we find the Higgs boson?
Yes.
It is crystal clear that we found a particle and that particle is exactly what we predicted.
It talks to the other particles in the same way.
It has the right mass.
It has the same lifetime and all those things.
But there is a puzzle.
So this is what we have.
We don't have blatant disagreement between theory and experiment.
What we have are puzzles, right?
What we have are mismatches between our informal expectation and what reality is doing.
So in one way – so there's a number, which is the mass of the Higgs boson.
We measured it, okay?
130-some times the mass of a proton.
But there's a guess as to what the mass should have been.
If nature were natural, nature is natural.
But if our notion of nature worked out the way it was, what should the mass of the Higgs boson be?
And it's literally a quadrillion times bigger than what it actually is.
joe rogan
What's a quadrillion?
sean carroll
10 to the 15. Trevor Burrus I'm not making this up.
You can Google this.
The mass of the Higgs boson should be enormously bigger by sort of what our intuitive feelings about quantum mechanics and quantum field theory say.
So this is a known problem.
This has been known for a long time called the hierarchy problem.
So even before we discovered the Higgs, we knew it wasn't that heavy.
We knew it was much, much lighter than what it should be.
So the hierarchy problem was a known thing.
And people said, how could it be true?
Well, you have to change the theory a little bit.
You have to like add some new particles or predict some new features of physics going on.
And many, many people, myself included, were very optimistic that the Large Hadron Collider would find evidence for what was going on, would find more particles than just the Higgs boson.
It's found nothing else.
Maybe it would find supersymmetry or extra dimensions or strings or some new kind of combinations of old particles.
It's found nothing else.
So now we have a puzzle and no answers, right?
And that's the most frustrating thing because there – I mean people don't want to say this out loud, but here we go since no one is listening to this, right?
The last time particle physicists were surprised by an experimental result from a particle accelerator was in the 1970s.
Since then, we found new particles, but they were already predicted and expected to be there.
We've never found a particle since the 70s that no one had anticipated finding long before.
joe rogan
Well, just the idea of a particle collider as a layperson, as a person just looking on the outside, like, you got to create crashes.
Like, that's the only way to figure out what's going on with the basic building blocks of the universe.
You have to crash things into each other.
sean carroll
I know, yeah.
Well, so the secret to that is that really the world is not made of particles.
It's really made of fields, right?
That's quantum field theory is the label given to this.
For the electromagnetic field, for the light coming out of the light bulbs, that makes sense.
We figured out the fields first and only found the particles later.
But it's also true, as we were just talking about, for the particles like electrons, protons, quarks, neutrinos.
These are all vibrations in fields.
So what you should think about when you think of colliding particles, it's not little I think?
But when these particles that you made in the Large Hadron Collider hit each other, that sets up vibrations in every field in the universe, like very faint little jiggles up and down.
And then you look and you see, and quantum mechanics says there's a probability it will look one way versus another.
So the way you make it – how in the world do you make a Higgs boson by colliding protons even though the Higgs boson is over 100 times heavier than a proton, right?
The answer is really you're setting up vibrations in the Higgs field, which was always there all along.
And then you very quickly—actually, you can't.
The Higgs boson disappears so quickly you'll never see it.
You see what it decays into.
You see what it converts into.
The vibrations in the Higgs field get transferred to vibrations and other things, and that's what we observe in our detector.
So if you are able to do this sort of conceptual switch from particles to fields, then the reason why we need an accelerator and a collider to make new particles begins to make a bit more sense.
unidentified
Woof!
sean carroll
Doesn't it?
Don't you agree?
unidentified
Yeah.
joe rogan
Oh, I get it now.
There was something that I had read.
I'm trying to remember it.
sean carroll
One more thing.
If you're in a room with two pianos and you play one piano, the other piano will start vibrating along with it a little bit.
joe rogan
Ah, that's an interesting way to look at it.
sean carroll
That's the one field, the quarks and the gluons and the protons start the Higgs field vibrating a little bit.
That's what we eventually see.
joe rogan
I'm glad you mentioned gluons.
That's one of the things that I had read about that they did What they had either discovered or were able to observe with the Large Hadron Collider was I believe it's called quark gluon plasma.
sean carroll
That's right.
You got it right.
joe rogan
Thank you.
Which is an immensely dense thing.
The way they described it was something like something that was a fraction the size of a sugar cube would weigh as much as the Earth itself.
sean carroll
Yeah, that's right.
So usually what you try to do with particle accelerators is discover new particles, right?
So to do that, why haven't you discovered them already?
Usually it's because they're too heavy.
It takes a lot of energy to make them.
E equals mc squared.
If the mass is big, you need a lot of energy in as small as possible region.
That's how you make new particles.
So to do that, you take some particles that are pretty small like protons and you smash them together and that's how we discovered the Higgs and we're looking for other things.
But maybe your goal in life is not to discover new particles but to understand the particles that we already know about, right?
In that case, maybe you want to see what happens when you get, like you say, a huge number of particles together in the same place with a lot of energy and see how they interact with each other and make a plasma.
A plasma is like what's at the center of the sun, right?
But instead of electrons and photons, we're going to make it out of quarks and gluons.
So instead of smashing together protons, a proton has three quarks each, right?
We smash together the nucleus of a heavy atom, like an iron or a lead atom, right, which has, you know, dozens of protons and neutrons in it.
So we get as many particles as we can squeezed together in the same place.
So the energy is a bit more diffuse, but we get to study how they interact with each other because that's what conditions were like near the Big Bang.
Lots of particles going on.
It wasn't just two particles smacking into each other.
So we're learning a lot about what conditions were like in the very, very early universe.
joe rogan
What is the mass of this stuff, this quark-gluon plasma?
There's some insane number that I remember reading.
sean carroll
Yes, but my neural implant is failing me, so I cannot remember the number right now, but we could Google it.
I don't know.
It's very dense.
joe rogan
Gigantic, massive.
sean carroll
It's a bit of a cheat, right?
Like, you know, so I always – I get laughs when I give talks on the Higgs boson because I mentioned that the lifetime of the Higgs boson – I already said it disappears very quickly, right?
So I say it's one zeptosecond, which is true.
And just like, you know, you – when I said quadrillion, you're like, what is that number?
And I said 10 and 15. But who cares?
Right.
The point of a zeptosecond is really short.
So I say it's a zeptosecond, which is a really short period of time.
And everyone laughs.
It's 10 to the minus 21 seconds.
But who cares?
Like if I had said 10 to the minus 28, would that have changed your opinion of the Higgs boson in any way?
Like it's a really short period of time.
unidentified
Right.
joe rogan
Like five quadrillion.
Is that more than four quadrillion?
sean carroll
Yeah.
It doesn't really affect your life in any meaningful way.
joe rogan
What is going on right now with science that is particularly compelling to you other than things we've already discussed?
sean carroll
I'm very interested in entropy and complexity, complex systems.
There's a wonderful place in New Mexico in Santa Fe just called the Santa Fe Institute which is devoted to the study of complex systems.
Physicists are really, really good at studying simple systems, a couple of particles at a time, right?
There are certain techniques they have.
This is why we have theories that explain all the data because we're asking questions about the simplest possible things that we can.
Once you have a bacterium or an elephant or an economic system or an internet, these are very, very complex systems with many moving parts that interact with each other in complicated ways.
And so you can start asking yourself questions about are there laws that govern the behavior of these complex systems that we wouldn't have noticed if we just studied them piece by piece?
The answer is a little bit yes.
I hate to keep advertising my podcast, but we had Jeffrey West on the podcast who was- Why do you hate it?
Yeah, I shouldn't hate it.
joe rogan
That's the whole reason to be here.
unidentified
I'm lying.
sean carroll
I'm not actually telling the truth.
You solved through me there.
I love advertising my podcast.
So I had Jeffrey West, who's a brilliant physicist who actually started as a particle physicist.
And then when we were going to have – remember, we were going to build the superconducting supercollider in the United States.
This was going to be our version of the LHC, the Large Hadron Collider.
But the SSC would have been both sooner and better.
It would have been higher energy and more powerful.
joe rogan
That was during the Clinton administration, correct?
sean carroll
Yeah, that's right.
Well, it started during the Reagan administration and then Clinton let it be killed by Congress basically.
Yeah.
So Jeffrey West, who was a particle physicist at the time, said like, that's my life's work.
Like I was hoping for this to come online.
I'm not going to see.
What else can I do?
And he found that in biology, there are what is known as scaling laws.
So if you look at different organisms like mammals or whatever, right, you can plot different quantities like their mass and their metabolism or their lifespan, things like that.
And it turns out that they are related to each other.
It's not – if you know how heavy a mammal is, you know how long it's going to live.
You can figure that out.
And in fact, it's related to the metabolism also.
So there's a wonderful – so basically the bigger you are, the longer you live.
Also, the bigger you are, the slower your heart beats and they exactly cancel out.
So that every mammal lives for about 1.5 billion heartbeats on average.
joe rogan
I've read that and I relayed that to my friends that are runners.
And I was like, you've got to think, if you're an ultramarathon runner, like my friend Cameron Haynes, he runs these 240-mile runs.
It's ridiculous.
sean carroll
My nephew just did that in Death Valley.
I keep saying badass, but it's like the bad water.
135 miles, yeah.
joe rogan
These races are crazy.
So you've got to think the exertion over long periods of time, you're juicing up your battery.
sean carroll
You don't get a finite number, a fixed number of heartbeats to begin with.
joe rogan
But you know what they do do, though?
It lowers their resting heart rate, which is fascinating.
sean carroll
Yeah, that's right.
joe rogan
So all this extreme exercise, oh, you're wasting heartbeats.
But also, your heartbeat is probably like 78, whereas theirs is 34. Yeah, now they're winning overall.
Yeah.
sean carroll
It totally compensates.
joe rogan
It's weird, right?
It's a weird sort of counterintuitive thing.
sean carroll
But again, the billion and a half is just an average.
But the point is, so Jeffrey West and his collaborators said, why?
unidentified
Why?
sean carroll
Why is it that, you know, you can't make an animal that's twice as big and lives the same length?
What's going on?
So they actually came up with a theory based on the fact that our bodies are networks, right?
Our circulatory system or our respiratory system or our nervous system, they all have the same structure like trees, right?
Like fractals.
And they are able to show that if the resources that our biology uses Travel through these fractal networks in a three-dimensional space, right?
We're three-dimensional beings.
Then you get these scaling laws.
You get this universal behavior and it fits the data and now you can extend it to the behavior of things like cities and corporations and stuff like that.
So when you get people in a city, they walk faster, right?
Like people in little small towns mosey down the street and everyone in the big city walks faster.
And why is that?
Like what's going on?
And there's – you would not be surprised to learn that there are more patents that are generated in a big city than a small town.
But there are even more patents per person.
In a big city.
Like living in that dense environment changes the rate of innovation and things like that.
So they're studying how we can try to extract these not quite as precise as particle physics but still very general robust relationships between these large systems and learn from that how to make things more sustainable, more creative, more innovative, more livable and things like that.
So I think all this stuff is very fascinating.
joe rogan
They've actually done studies where they've put cameras up on streets and they watch people walk by and the amount of footsteps they take per minute, they can accurately depict or they can accurately predict how many people live in that city.
sean carroll
I believe that.
That's cool.
joe rogan
It's insane.
Just based on how and also how fast you talk.
sean carroll
Trevor Burrus Yep.
How fast you talk, how fast the line moves in the DMV and the post office.
I think it's Dublin.
I'm not exactly sure but Jeffrey West has this picture of Dublin.
There's this tourist area and so it's both a big city where a lot of people live but it's also a famous tourist destination where foreigners come in and wander around, right?
And the locals who live in a big city and want to get where they want to go became so frustrated with all these moseying tourists.
They literally made walking lanes for the locals where you have to walk fast, right?
You're not allowed to meander.
joe rogan
Oh, wow.
That is interesting.
That's interesting.
Listen, thank you very much for doing this.
Thank you for being you.
