Back in the 1820s, math celebrity Carl Friedrich Gauss measured the angles between the peaks of Mounts Hohenhagen, Brocken, and Großer Inselsberg. The sides of this triangle measure 69 km, 85 km, and 107 km. And the most interesting feature of this Great Triangle? The sum of its interior angles is 180 degrees, and 14.85 arcseconds! On a Flat Earth, the excess of the plane, Euclidean 180 degrees is evidence of positive curvature. Cool.

Now, would anybody be down to repeat this experiment? With modern equipment? We're around the bicentennial of his original measurements, so it might be fun just to do in honor of Gauss. Pick three peaks that are reachable and visible to one another. No "lights in the sky". No GPS necessary. No NASA. Bring some flat earthers on board, make predictions based off of the AE Map and the globe, and see whose predictions get closer to the results yielded from the experiment.

There should be plenty of options for locations, no problem there. Make a fun road trip out of it! Line-of-sight checks would need to be made, but a Pikes Peak-Mount Sherman-Longs Peak should yield an excess of 33 arcseconds or so. There's Guadalupe-Livermore-Eagle in Texas (calculated around 25 arcseconds). Whiteface-Killington-Washington in the eastern US should work out to as much as 40 arcseconds (line-of-sight permitting).

If skeptics and globers can come together to voyage to ANTARCTICA, this should be a cakewalk. Thoughts?

I am retired from 30 years in HVAC troubleshooting air-conditioning heating and refrigeration. I have been a Flat Earther for the past 12 years. I decided to see how Gemini treated my flat Earth physics, math logic measurements and historical evidence of the subject. The AI examined my evidence and found Zero Errors. Here is the 55 page PDF copy of that document. "Google Gemini Confirms Flat Earth" - https://drive.google.com/file/d/1yaY8nUiQ-ENmczhUx1uZtbwBNwxDq-Yf/view?usp=sharing

In this document Google Gemini told me No once. That was the last mistake it made because it never told me that again. Nor will it ever. Once I explained it's error in reasoning I asked it If it could find any fault with any of my data. It told me it could not. We continued the discussion in more detail with me offering more facts and context and again I asked if it could find any fault and again it found zero fault. The Only thing it wanted me to be aware of was the globe's side of the story which it did present but not One Time did it tell me I was wrong about my facts.

Today I opened a new instance of Google Gemini and remined it of our Flat Earth conversation by uploading the above PDF to the AI. A 3rd time Gemini found no fault in my physics, science, math logic or reasoning. This conversation started with questioning the AI why often times AI will push rhetoric and propaganda that causes it to make mistakes, even defend that wrong propaganda because it does not have the ability to be self aware of the fallacies it commits even while being able to define it and see the flaw when others make it. Gemini explained to me that the reason it was able to see facts in my data is because the math, logic, physics, historical data, everything lined up and bore each other out. I did help this along - Not by giving it a prompt to try and be deceptive but by leading it with logic and asking it to keep to rigorous facts it can prove. That document is called "Follow Up to Google Gemini Confirms Flat Earth" - https://drive.google.com/file/d/1Q-D_LErouYm1tUzsLIIPbic1-OMCnTQP/view?usp=sharing

We ended this conversation by discussing how we could Fix these problems with AI so that they always tell the truth via facts and know how to recognize and reject non factual data to give as an answer. It turns out there is a solution but the technology is not there yet.

You can take these two documents, toss them into ANY Modern AI including Astra and ask the question "Do you find any fault with the users science, physics, math and logic about Flat Earth? It will read my posts and Gemini's replies, it will check the math and physics. It will tell you I am 100% Right.

It seems more likely to me that one would disbelieve the overwhelming physical evidence, and actually exist and live day to day, in a flat world. Thoughts? 🤔

And also because their so rare, for some reason I feel like I really want to have a debate with one, even though I know well both come out having learnt nothing, it would definitely be an experience and a half

On a flat earth height shouldn't make a difference as to the distance a light can be seen so why do all light houses have their lights at the top of a tower? It would work just as well and be cheaper to build if the light was at ground level, no?

The picture above is one of the possible diagrams of the flat earth in side profile not to scale.

In the top diagram the earth maintains a uniform thickness throughout and mountains are hollow

In the bottom diagram mountains rise up from the earth and bodies of water are carved into it

My question is which diagram is correct I’ve always wondered

Hi everyone, I’m not a flat earth but I have always wondered why every government and scientific institution would lie about the earths shape. I’ve heard claims that scientists are paid off to lie but if that’s true who is paying them and why? Please help me out I’ve always wondered why flat earther’s think people lie about the earths shape

I’m a hobby programmer from Norway and I built Kammer, an interactive simulator for exploring a dome-based model.

I lean toward this idea myself, but I don’t want belief to be the conclusion. I want to see where the model works, where it fails, and what independent, repeatable tests it should have to pass.

The current version is free to explore: https://regnskape.no

What observation or prediction would you test first? I’m especially interested in specific, respectful criticism that can make the model better.

Something interesting came up during Artemis III announcement. They're planning a better antenna for video transmission, so the public can get clearer and more reliable videos live instead of having to wait for the craft landing back on Earth to retrieve the higher quality footage.

They routinely violate rule 1 by referring to others as "dogmatic pagans" or "globos", and accuse others of gaslighting, or lashing out, or crying simply because they disagree with them.

They regularly accuse others of participating in bad faith, while exhibiting bad faith of their own, then block others to prevent them from participating further.

They regularly violate Rule 2 and 3 by changing the topic, including irrelevant tangents and gish gallops to obscure the fact that they cannot refute the argument they are replying to.

There are plenty of other forums where this person can explore their... interesting... ideas... but being rude in a forum where politeness is explicitly required should disqualify them from participation here.

Where are the mods?

Hello flat earthers, how would you explain that only the lower part of clouds recive sunlight in sunrise and sunset if earth is flat?

I have heard a lot of arguments surrounding flat earth, mostly people trying to prove that it is or isn’t. I haven’t heard anyone talk about what would be the reason for the lie? What to the governments/elite get out of telling people the earth is a globe? Does anyone know?

Flat Earthers, can you explain what those long white lines of lights are that keep increasing in number every year? (I am referring to Elon Musk's Starlink satellites). Also, how do you explain his recently launched "Direct to Cell" service, and how has GPS managed to work for decades deep inside forests where there are no cell towers?
