Theories Versus Hypotheses 00:04:15
Today we've got another student questions episode.
This week we've got questions about theories versus hypotheses, the FDA, the destruction of the Georgia Guidestones, the test tube baby company EctoLife, tachyons that move faster than the speed of light, doctors selling woo, the flat earth, and the ethics of paranormal tourism.
And all of that is coming up right now on Skeptoid.
Hi, I'm Alex Goldman.
You may know me as the host of Reply All, but I'm done with that.
I'm doing something else now.
I've started a new podcast called Hyperfixed.
On every episode of Hyperfixed, listeners write in with their problems and I try to solve them.
Some massive and life-altering, and some so minuscule it'll boggle your mind.
No matter the problem, no matter the size, I'm here for you.
That's HyperFixed, the new podcast from Radiotopia.
Find it wherever you listen to podcasts or at hyperfixedpod.com.
You're listening to Skeptoid.
I'm Brian Dunning from Skeptoid.com.
Student Questions, Guidestones, and Tachyons.
Welcome to another Student Questions episode in which people send in their questions from all over the world, and I do my best to give them all a miniature Skeptoid treatment.
You might notice today that not all of our questions come from students.
In fact, in what might be a first, I don't think any of them are from students, but that's okay.
For a long time, these episodes have been open to anyone.
Students of life, students of the School of Hard Knocks, whoever.
Regardless, they're always fun.
Without further ado, let's dive right into our first question.
Hi, Brian.
I'm Diane from Oregon, retired science teacher and lifelong student.
I'm curious as to why you use the terms theory and hypothesis interchangeably.
I know that in common usage, theory means a working explanation for which more evidence is needed, but that's not what it means in science.
And I think this leads to confusion that contributes to scientific illiteracy, as in, evolution is just a theory.
Thanks.
Thanks for pointing out the important distinction.
However, I must beg to differ.
I most certainly do not use them interchangeably, and a number of episodes have discussed the difference between them.
A hypothesis is a proposed explanation that needs to be tested to establish validity, while a theory is a widely accepted explanation supported by solid evidence.
What you've probably heard is me discussing crackpot ideas that their creators have named, such as the stoned ape theory, the electric universe theory, or the flat earth theory, names which have come into common usage and which include the word theory.
I use the recognized name so people know what I'm talking about.
As I explained in one such recent episode on polyvagal theory, It's worth noting, of course, that PVT does not satisfy the requirements to be elevated to the status of a theory, which requires support from multiple lines of evidence, substantial experimental replication, and testable predictions.
It is a hypothesis at best, but not so much even that, as it is not really a suggestion to explain an observation.
It's best described as a conjecture.
But since polyvagal theory is its common name, I call it that in recognition of the fact that if I didn't, nobody would know what I was referring to, and I'd sound like a maniac.
Next, we have a question from Brandon.
Hello, Brian.
In this week's episode, when you were speaking about magnetic therapy, you mentioned that the FDA only speaks about a product's safety, not necessarily its efficacy.
I was wondering if you could spend some time talking about what the FDA actually does and give us some more clarification on what they do rather than just live with myths.
Thank you, buddy.
Have a great week.
Great question, but a thorough discussion of that could never be squeezed into a skeptoid episode.
What Was in the Time Capsule 00:02:38
This is mainly because there's so many different things that the FDA approves and doesn't approve, and their approval means something just a little bit different for each.
There are drugs, but excluding some types, biological products, some kinds of medical devices, but not others.
They regulate some things like human cells and tissue, but don't approve them.
Food additives.
Color additives, but only in regulated products.
And lots of things that they explicitly don't regulate or approve.
Really, the best thing for anyone who wants to learn more would be to visit the FDA website, and there's a page called, Is It Really FDA Approved?
That's a great starting point.
Sorry to do that to you.
Patrick wrote in with this.
Hi, Brian.
I'll keep this short.
What happened to the Georgia Guidestones and what was in the time capsule buried underneath them?
So if you don't know about the Georgia Guidestones, they were a granite monument built anonymously in rural Georgia.
Covered in multilingual inscriptions advocating policies like limiting world population to 500 million, eugenics, a single global language, peace, reason, environmentalism, kind of a hodgepodge of philosophies.
Skeptoid episode number 108 was all about them, if you want the complete story.
In July 2022, the Guidestones were partially destroyed by an explosion, and the teetering remains were then demolished by officials for safety.
As of this writing, the crime remains unsolved, but it's not hard to guess.
The guidestones had been constantly vandalized, often with slogans written by local evangelicals accusing them of being satanic.
Two weeks before that happened, I did a skeptoid follow-ups episode revealing that their creator had finally been identified.
You can check out skeptoid number 837 for the details, but it was a local doctor, a Christian nationalist, and avowed white supremacist.
He actually used the pseudonym Christian when he had the guidestones built.
Imagine how the dynamite-wielding vandals would feel if they knew they'd just blown up the creation of one of their own.
As for the time capsule, there wasn't one.
A partially completed granite plaque at the site promised one buried six feet beneath it.
But when the contractors demolished the remains, they dug for it and found nothing.
Engineers stated that the red clay soil had not previously been dug up.
Hello, Brian.
This is Jack in Friday Harbor.
Sailing to a Skeptical Conference 00:03:02
Here's my question for you.
I read today that there's a company called EctoLife that is promoting the possibility of birthing 30,000 babies a year artificially in a factory setting.
It seems to me this would be worth a little skeptoid investigation.
Thanks.
Love your work.
I hate to break it to you, Jack, but it's pure fiction.
Filmmaker Hashim Al-Ghaili created an eight-minute computer graphics film short that's like a marketing video for the fictional EctoLife company that he made up.
Apparently enough people were fooled by it and thought it was real that they started sharing it around.
And, well, here we are.
Harold writes, My physics professor said that nothing travels faster than the speed of light in vacuum.
But I've heard that there are particles that travel faster than the speed of light called tachyons.
Do they exist?
So this is a really weird question in that a discussion is probably only meaningful to particle physicists.
For the average Joe on the street who wonders if there are particles that travel faster than light, the answer is no.
Tachyons are hypothetical.
But to physicists working equations, tachyons are useful in a way not too different from how the imaginary number i, the square root of negative one, is useful to mathematicians.
An in-depth discussion is beyond the scope of this podcast, which is my easy out for saying it's way over my head.
But you can get started by thinking of it like this.
If we add energy to a particle with mass, it would speed up.
But if we have a tachyon with imaginary mass, we'd have to take energy away from it to speed it up.
But don't worry, the idea of tachyons doesn't mean there are actually things whizzing around faster than the speed of light.
Special relativity remains intact.
Hey everyone, I want to remind you about a truly unique and once-in-a-lifetime adventure.
Join me and Mediterranean archaeologist Dr. Flint Dibble for a skeptoid sailing adventure through the Mediterranean Sea aboard the SV Royal Clipper, the world's largest full-rigged sailing ship.
This is also the only opportunity you'll have to hear Flint and I talk about our experiences when we both went on Joe Rogan to represent the causes of science and reality against whatever it is that you get when you're thrown into that lion pit.
We set sail from Málaga, Spain on April 18th, 2026 and finish the adventure in Nice, France on April 25th.
You'll enjoy a fascinating skeptical mini-conference at sea.
You'll visit amazing ports along the Spanish and French coasts and Flint will be our exclusive onboard expert sharing the real archaeology and history about every stop.
Selling Paranormal Tourism Ethics 00:08:20
We've got special side quests and extra skeptical content planned at each port.
This is a true sailing ship.
You can climb the rat lines to the crow's nest, handle the sails.
You can even take the helm and steer.
This is a real bucket list adventure you don't want to miss.
But cabins are selling fast and this ship does always sell out.
Act now or you'll miss this once-in-a-lifetime opportunity.

Hope to see you on board.
That's skeptoid.com slash adventures.
Hey, Brian, Eric from Wisconsin.
Just wondering how you handle experts that sometimes recommend non-expert things.
For example, a physician suggesting doing acupuncture for pain.
Thanks.
You've got this in virtually every field.
Medicine is particularly problematic.
Doctors are human and only incrementally less likely than the average person to believe in some alternative therapy and to be happy to sell it.
And to the extent they're not violating medical ethics, they have every legal right to do so.
That leaves the onus on you, the consumer.
You can give them a bad review online, but that doesn't make much difference.
The next customer who loves the alternative therapy will leave a positive one to counteract it.
Really, this is just one more argument in favor of having a good general science literacy.
You can't protect everyone, but you can protect yourself and your family.
Here's a question from Robert.
Hi, Mr. Denning.
I've been reading a lot about the Earth being flat.
How do you know that the Earth isn't flat like one of those ancient compact disk things?
Or it's round like a basketball.
Thanks.
It's a fun question, but quite honestly, even the most science-y among us don't always necessarily have the best rebuttals at the tip of our tongues.
Here are a few quick ones that are irrefutable.
Constellations in the night sky differ based on your location, in such a way that is consistent only with the Earth being a sphere.
Gravity keeps you standing upright.
If Earth were a disk, when you're out near the edge, you'd be standing at a sharp angle, since gravity pulls toward the center of mass.
You can see farther from higher up.
If you look at the horizon through binoculars, you will see a very different sight from the top of a tall building than you would from down lower.
During a lunar eclipse, whenever the shadow of the Earth falls across the moon, you can clearly see that it's round, even when the moon is down low near the horizon.
Well, that's enough for now.
If you still can't convince them with that, my advice is to save your breath.
Hi, Brian.
This is Susan Gerbig from the Gorilla Skepticism on Wikipedia project.
I'd like your thoughts on paranormal tourism.
I recently wrote the Gulf Breeze UFO Wikipedia page and was surprised to learn that Gulf Breeze, Florida gained by increasing tourism dollars as several UFO conferences were held there and TV shows like Inside Edition and others expose the public to the area.
Places like the Winchester Mystery House and much less well-known buildings rely on the paranormal aspect to bring in much needed funds to keep the buildings maintained.
I find the history of these places interesting, but don't think enough people do, so they sometimes go the paranormal route.
Your wisdom is appreciated.
So this is a difficult question.
Every week when I do a Skeptoid episode about some paranormal thing, for example, the Cottingley Fairies, I'm well aware that most of the people who look for it using a search engine are more than likely going to be believers in it.
So I might well tweak the episode title toward clickbait to increase this traffic.
But once they get to my page, it's very clear that this is a fact-based exploration of the phenomenon.
This is a bait and switch situation that's going to exist regardless of how I title the episode.
So I use that to the best advantage to spread the message of critical thinking as far and wide as possible, because that's what Skeptoid is here to do.
Now I'd like to say that the same logic could be applied when you attract tourists by leveraging a ghost story.
But then you could hit them with a science message instead when they arrive.
But no, you can't do that because you're deceiving them into spending money to travel, then giving them something other than what you promised them.
And that's not cool.
People are always going to be interested in paranormal travel, and anyone who sells it to them should give them what they paid for, in my opinion, just as a basic honest business practice.
My hope is that in the gift store at the end of the ghost tour, you've got the skeptical books front and center.
An honest operator will give them the entertainment they were promised and then make sure that the honest account of the attraction is available for any who are open to it.
If I owned the attraction, I'd sell the honest version to begin with, because I've learned from 16 years of Skeptoid that the truth is always more interesting than the fiction.
It just takes more work to sell that effectively.
But doing that work is why I go to bed at night with a clear conscience.
And thus concludes another student questions episode.
