Self-Correction and Hollow Spheres 00:04:20
If we're going to do a show like Skeptoid and claim to be some sort of beacon of critical thinking and learning to tell what's true from what's not, then we need to cling to one of the core scientific principles, self-correction.
Believe it or not, Skeptoid sometimes is wrong.
And today, we've got a whole raft of corrections to past episodes.
How many of these did you catch?
That's up next 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.
Error Correction, Tokyo Drift.
Once again, it's time to dip into the mailbag and fix some factual blunders in past Skeptoid shows that were caught and corrected by you, the Skeptoid listeners.
Today we've got corrections that both excite and illuminate the mind, as they not only make our brains better, but they're fun and cool.
We're going to fix our episodes on hollow earth theory, on the Aaron Brockovich case, weather satellites and 5G internet, the makeup of the core of the Earth, massacres during pandemics, a tidbit on the Mary Celeste, and to round out the field, what episode would be complete without a discussion of ninjas.
We're going to get started with a very fun correction.
It goes all the way back to episode number 343 on the hollow earth theory, which was a series of beliefs held by a few outsiders at various points in history.
There were a number of models espoused by various believers, but one of the most common held that the outer surface of the Earth, where we all live, is just as it actually is in reality, but that the Earth is a hollow shell and there's a whole other civilization living on that inside convex surface.
Listener Paul, president of the Flemish Belgian Skeptics, recently wrote, This reminded me of an exercise during my engineering studies.
I remember we had to calculate gravitational attraction within a hollow sphere.
The resulting force was zero, anywhere inside the sphere.
This means you could not live on the interior surface.
You would just float away.
I've never seen this used as an argument against a hollow Earth, which doesn't really require arguments, of course.
So I'm wondering, did I remember my physics exercise of 45 years ago correctly?
Now, if that's correct, it shows that the believers in this particular hollow Earth model were wrong, but that I was also wrong in not catching the physical impossibility.
So I passed this along to my favorite physicist, currently a fourth-year student in astrophysics, and she replied, Hello, Paul, I'm Erica, Brian's daughter, and he checked with me on this subject since I am currently in my senior year studying physics.
You remembered correctly.
The resulting gravitational attraction within a hollow sphere of uniform density is equal to zero.
It's an excellent physics exercise and wonderful practice for many students in derivations of formulas.
I'm a TA this year for introductory physics, and I would really like to throw this at our students.
Physics is really just the coolest.
So wrong I was, and this very cool note has been added to that episode transcript on the website.
Recent episode number 743 covered the famous Aaron Brockovich case, which became something of a poster child for ambulance-chasing lawyers who manufacture mega-dollar lawsuits against super-deep pockets like those of public utilities.
Water Vapor and Arbitration Errors 00:03:09
Because the science in these cases is often shoddy, the plaintiffs tend to prefer to avoid going to court where they might be required to meet a standard of evidence.
And the Aaron Brockovich case was a classic example.
This particular case went to arbitration instead, a process which I described as one in which the arbitrator has to craft a settlement that both parties agree to.
Listener Wilco wrote, Both parties have to agree in a mediation, not in arbitration.
In arbitration, the arbitrator arbitrates, and the parties have to abide.
And there's usually no right to appeal.
I'm not a legal expert, but I'm familiar with mediation and arbitration through my work in real estate.
Otherwise, I wouldn't have noticed it.
And he provided an authoritative supporting reference.
I was erroneously describing mediation, not arbitration.
It's been corrected on the transcript, and fortunately, this error had no bearing on any of the episode's conclusions.
Apologies to any mediators and arbitrators who may have been offended enough to consider suing me.
In another recent episode, number 739, we talked about one science-based concern over the rollout of 5G cell phone data, interference with certain weather satellites.
In short, one of the 5G frequency bands is very close to a band used by a couple of modern weather satellites to detect water vapor.
So if the required tolerances aren't followed, a city covered by 5G towers could possibly look like a bank of moisture to a satellite so equipped.
As these satellites have only been flying since 2011, I retorted to some of the claims that 5G would send weather forecasting back to the 1950s by stating that at worst, weather forecasting would be sent back to 2011, not to the 1950s.
Listener Leonard wrote in, This is simply not true.
The ability to see water vapor from satellites goes back many decades.
A quick Google finds many links to support this.
And he provided links to articles describing earlier water vapor detection satellites.
There have been quite a few different technologies flying on different satellites, going back, as he said, many decades.
We traded quite a few emails, and he's a physicist, so he knows his business, but working through all the references we dug up, we found no satellites flying prior to 1998 that used this particular frequency for water vapor detection.
So I've updated the transcript accordingly, but remain open to any further corrections, as this turned out to be a surprisingly complex case of frequencies and technologies and satellites.
Regardless, looking back like this is a purely theoretical exercise.
If we decided not to enforce the tolerances on 5G towers, what old historical weather satellites that are no longer used would have been impacted?
It doesn't really matter, so it was kind of a goofy comparison for me to make.
Earth's Magnetic Field Adventures 00:02:23
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 finished 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.
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.
Get the full details and book your cabin at skeptoid.com slash adventures.
Hope to see you on board.

Episode number 728 was about what would happen if the Earth's magnetic field flipped, claimed by many on the internet to be the end of civilization.
As part of my discussion on what exactly happens when the Earth's magnetic field flips, I said the Earth's interior is mostly molten iron.
Listener Scion, a geophysicist and volcanologist, was quick to pounce on that one.
The crust and mantle, 1% and 84%, are both solid rock, and the inner core, 1%, is solid metal.
Only the outer core, 14%, is liquid, and it's partly nickel, too.
Which is, of course, absolutely correct.
Alcohol Myths and Premium Facts 00:08:22
My error was attributable to nothing less than pure laziness.
Oh, here's this thing that I think I know rattling around in the back of my head.
I'll just spout it out uncritically as if it's fact.
My son Andrew, a geologist, also rained hellfire upon me when he heard that, but Scion beat him to the punch, so his is the correction I give today.
The transcript has been corrected accordingly.
In episode number 722 on pandemic-related conspiracy theories, we talked about some of the horrible massacres that have taken place throughout history whenever there's been a pandemic.
Some group always blames some other group, Jews more often than not, and has sometimes massacred them in retaliation for the pandemic.
In the episode, I listed a bunch of massacres of Jews, including one called the Flanders Massacre, and gave the years 1348 and 1349 as the time they happened, which was during the Black Death.
Listener Bruno wrote in, Concerning the Flanders Massacre, do you have a source?
Mostly the Flanders massacres used for the throuncing French knights got from Flemish peasants and porters.
But that was in 1302.
There is a Brussels massacre.
Brussels was at that point not in Flanders, but that one was from 1370.
Maybe that is the one you meant?
Bruno is correct.
The Flanders Massacre is a name given to an unrelated event.
There was a massacre of Jews in Flanders during the Black Death in 1349, but it is, so far as I could find, not a specifically named event.
My error and the transcript has been clarified.
It often gives me a moment of pause when I come across something like this.
Historical massacres of Jews were so common that we get their names and years confused.
Now we're going to go way, way back to episode number 289 about the Mary Celeste, the ship that was found sailing all by itself with no crew aboard back in 1872.
I'll cut to the chase as the explanation is a bit long, but the mystery had to do with its cargo of alcohol stored in barrels made of white oak.
except for nine, which were accidentally in red oak.
Catch the episode if you want the full details.
One of my primary sources for the episode stated that the cargo was grain alcohol, which was being imported to Genoa for the purpose of fortifying cheap Italian wine.
Listener Philip wrote, It probably has no bearing on the mystery, but the cargo was denatured alcohol.
No way, I thought, as the records are pretty thoroughly documented.
This episode was nine years ago, so I had to go back to whatever references I listed for the episode.
And in not one of them could I find a reference to grain alcohol.
So I started over and went to Wikipedia in order to get some links to some of the latest and greatest authoritative references on the Mary Celeste.
And guess what?
Everyone that mentioned the type of alcohol gave it as denatured alcohol, which has been rendered poisonous and not suitable for fortifying wine.
Today, denatured alcohol often has methanol in it, so you wouldn't want to drink it.
Without being able to verify whatever my original primary reference was, and without being able to say what passed for denatured alcohol in 1872, I'm not prepared to say for sure that my original primary source was wrong and that the cargo was not for fortifying Italian wine.
But I am prepared to say that what I reported in the episode is at odds with today's primary sources, so this has been noted on the transcript.
If you have additional information that can clear this up, please send it my way.
Episode number 509 was about ninjas.
What they really were, what they did, and what their purpose and techniques actually were.
Turns out to have had little to do with today's pop culture representation.
I used their depiction in the 1967 James Bond movie, You Only Live Twice, as a major influence on today's pop culture version of ninjas, almost every detail of which is wrong.
I said, Everything about the ninja depicted in this scene is accurate, except for a few details.
Real ninja didn't wear black, they didn't fight in open battle, they didn't work in large teams, they weren't trained in any special fighting techniques, and they weren't called ninja.
Other than that, it was spot on.
Well, listener Richard caught me in an error.
Although virtually every other ninja on television or in the movies wore black, the ones in You Only Live Twice wore gray.
In You Only Live Twice, the ninjas wear gray.
The rest is as realistic as any Bond movie.
For example, the cast are bipedal.
And as always, the transcript has been updated with the correction.
One final quick one.
In episode number 693 on the age of the great Sphinx in Egypt, I mentioned alternative historian Graham Hancock and incorrectly identified him as an ancient alien theorist.
Several of my colleagues pointed out to me that Hancock's pseudo-scientific ideas of an ancient advanced civilization do not include any alien origin, and that he's more accurately described as an ancient advanced civilization theorist or alternative Atlantis theorist.
My apologies to Mr. Hancock and the correction has been noted on the transcript page.
So listeners, keep those corrections coming.
No matter how hard I work at making Skeptoid as accurate as it can be, there's always that conflict between the point of diminishing returns and the need to meet a weekly production schedule.
So I'll always get something wrong, and all I can do is hope that it's something pretty minor.
