Lies

• Spreads the lie that American schools once taught flat earth. In his efforts to spread this lie, Weiss has committed elder abuse.
• Spreads the lie that Polaris has been seen from the Southern Hemisphere.

Leaky App

DIRTh's app is spectacularly insecure. It's been known to leak user email addresses, coordinates on the globe, and passwords in the clear since October 2024 and is still not fixed as of February 2026.

The app computes distances internally using the Haversine formula. See Image.

Weiss-isms

"Why don't we see any land when we're looking down at the ocean?”

“West is where you are, south is everywhere else.”

About April 8, 2024 Total Solar Eclipse: “Whatever it is that is blocking the sun isn’t in front of it, it’s behind it”

“If refraction were real, somebody should be able to walk down a city block and take a right-hand turn, and if they went far enough, they should refract back out so you could see them on the same avenue”

"All your listeners can see it"

"Spectroscopy needs to be in a container"; an assertion he made while debating Professor Dave.

Antisemitism

David Weiss is a Jew who had a Bar Mitzvah. On May 21, 2025, he hosted a Zoom call where about 80 Rabbis and devout Jews were invited. Dave brought Austin Whitsitt, a Holocaust denier and antisemite, to the call. During the call, one of the participants asked Dave if he would denounce antisemitism. He refused.

In the email thread after the show, Dave requested to be removed from the email thread, but before he left, he was specifically asked to denounce Holocaust denial or antisemitism:

David Weiss, do you denounce Antisemitism?

A simple “yes” will do.

Or any other response including no response is clearly “no”.

He refused to answer, making his position clear.

Knowledge about the model

DITRH claims that people on the globe side are not qualified to talk about the globe for not knowing all the Trivia. So let's make a table about what we know about the globe and what Dave knows about flat earth, to see if he is qualified to talk about flat earth.

Question	Globe	Flat earth
Radius of Earth	6371.0 km	Unknown
How thick is earth	12,742 km	At least 12 km
How fast is it spinning at the equator	Once a day	Not applicable
How fast does the sun move around earth	Not applicable	Unknown
Distance between sun and earth	About 151 million km	Somewhere between "it's in the clouds" and a few thousand km.

According to his own standard he is not qualified to talk about earth's shape.

Chicago Skyline

Dave: They don't talk about, hey, across Lake Michigan, I can see Chicago 57 miles away.

Apollo The Original: Mhm.

Dave: Right. And I can't see the very very bottom of the lowest buildings, but I can see the rest. Well, the top of the tallest building should be a couple hundred feet below the curve, but we can see the whole city.

Dark Star analysed the photo and showed there is a lot more missing than just the bottom of the lowest buildings.

The radius has been debunked

Dave: The radius the line from the center of the earth to the surface. It's three, nine, five, nine, 3,959 miles. That's been debunked because the radius tells us the circumference. The radius tells us how much curvature there is over a certain distance. And we can see things far beyond that physical limitation of a globe. So the radius has been debunked. What does that mean? That means that all of the planetary distances, the moon, the sizes, that's been debunked. Space travel has been debunked. Our solar system's been debunked. Everything has been debunked when the radius is debunked. The Earth is flat and it's provably so.

As the previous example already showed, he ignores the atmosphere.

Antarctica

Mountains and dome

Dave: There's mountains in Antarctica. They call them uh there I mean the names of the mountains are very weird. But um there's supposedly mountains there higher than Everest, but they don't tell us about that.

Apollo The Original: Then How do you know that?

Dave: Well, this is information that we have from some explorers from from old encyclopedias. The encyclopedia from 1958 says at 80 degree 80 or 85 degrees I forget 80 degrees 80 degrees south which is way south farther than any one is allowed to go and and independently they say that there's a domed ceiling at 13,000 ft.

The highest peak in Antarctica is the Vinson Massif at a height of 4,892 m (16,050 ft), which is significantly smaller than Mount Everest.

The encyclopedia American does talk about a dome, but in this context it's a geological structure. It should be obvious to anyone that no one would measure the height of a dome near its edge, but always at its highest point.

Apollo The Original even checks it himself with Dave present.

Antarctic Treaty

Dave: Um what's out there? There's no free and independent exploration. All the countries in the world that are waring with each other, they all agree nobody can go to Antarctica. And that's a fact. No. Well, you can't go.

They'll say, "Yes, you can. You can buy a trip. All these people go. Thousands of people go."

Not thousands. You know, some people go every year, but um they only take you to the very tip of Antarctica. the very, you know, that little spit that comes out near South America. They take you to a little island there. Um, and that that's all they let you uh see. They only take you to um I can share this with you. Let me let me just let me do that. So, I'm going to show you the bases. So, they only take you there. There's two little islands that they take you to. And one of them is called Deception Island, and the other one's called, I believe it's Rothschild Island.

First, the Antarctic Treaty literally tells people that it encourages freedom of scientific exploration and studies. Second, The Final Experiment showed that you can book a trip inland.

Population

Dave: You could take the population of the world and everybody can live in Texas and half of Texas would be empty, right? So, it's incredible how much space and that's with the number they give us 8 billion people. I think there's two billion people maybe.

Apollo The Original: So, they say that uh population of China's population.

Dave: Yeah. So, that that's this is good.

Apollo The Original: So, I did this exercise a couple of years ago.

Dave: Yeah. But while you're looking that up,

Apollo The Original: 1.4 Mhm.

Dave: 1.4 billion. Yes. Right. So they went from um well they went from 500 million to 1.25 billion in I think it was 20 years something like that. So that would require every couple to have five children. This happened during their one child rule.

China's population went from about 500 million to about 1.4 billion in around 60 years, 3 times longer than Dave claims.

• Promotes the "Flat Earth Sun, Moon & Zodiac Clock" app, which has been criticized for actively leaking user data.
• Vehemently rejected a free trip to Antarctica for TFE.
• Hard to distinguish from a potato.
• Has used his channel to share the MCToon harassment website.
• He joined a fake podcast hosted by It's a Rubiks, with Toon and FTFE as guests.
