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.

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 Flimish 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
