So, the burden is now on them to show why all this evidence for the round Earth is false. These things have themselves been tested, and no 'evidence' or explanations that the flat-earthers have thus far offered have stood up to testing.

The tweet then followed up with a question that lacked a question mark: 'Anyone want to buy SpaceX,' it read.Ī March 11 Instagram post sharing this image was flagged as part of Facebook’s efforts to combat false news and misinformation on its News Feed. 'The world is flat and I can’t get past the firmament!' read what looked like an April 25 tweet from Musk, referring to an unfounded belief that Earth is covered in a dome called the firmament. The earth isn’t flat, and SpaceX founder Elon Musk didn’t say it was, either.Īn image of a purported tweet from the entrepreneur suggests otherwise.
