According to this, it would be possible to see the 24h sun on flat earth.
I have to wonder what the anti-Truth scientologists have up their sleeve, paying big money for a bunch of people (including 2 Flat Earthers) to fly to Antarctica right now for a so-called "Final Experiment".
That isn't how science talks. Science is never "settled". You observe the facts, you hypothesize, and you make further experiments. Scientists should be melancholic and dispassionate. They should be boring, methodical and engrossed in the data and experimentation methodology. They should NEVER call names, NEVER go on youtube and yell, NEVER get bent out of shape, NEVER get embroiled in politics, and NEVER pick up a cardboard sign and call for the end of the world (or any degree of hype or alarmism). They should also never provide clickbait predictions to those who have business or advertising interests. Those things are the antithesis of true science.
Flat Earthers are the ONLY true scientists in the debate. Virtually all "globe earthers" limit themselves to bandwagon, authority, ad-hominem, possibility, and 50 other fallacies. That isn't science.
Science is about truth and observation, and making the theories align with the facts -- not the other way around.
