Why the baiting? Give Sabine Hossenfelder the money. She is a real physicist, and she isn't ridiculing flat earthers. They may be wrong, but they're not stupid. And they've been around a long time. So, what constitutes proof? There are mathematical proofs- that don’t necessarily align with with reality… And are you the judge, that doesn’t sound like a fair test, meeting your standard or proof? Are you looking for clever proofs, or absolutes? Baiting to debate? Baiting to ridicule? Some seriously credible people have believed flat earth theory. I am not arguing for flat earth, I am just saying there are better ways to go about it.
