B.o.B made us scratch our heads when he shared in a series of tweets that had “scientific” evidence the Earth was flat and not round.

Bobby Ray is so committed to being a flat Earth truther that he tried to confront Nasa and Neil Degrasse Tyson’s logic on Twitter (and wrote a diss track called “Flatline” at him), dropped a series of mixtapes where he comments on society, politics, and conspiracy theories, and now wants to launch a satellite through a GoFundMe to prove once and for all the Earth is flat.

Then there’s Kyrie Irving, who is also a firm believer that the Earth is flat. But he could be trolling with his stance, who the hell knows.

It’s enough to get Bill Nye so fired up that he wants to debunk every flat Earth theory out there. Complex's Khal and Frazier Tharpe sat down with him recently to hear his thoughts about the phenomenon.

“The dismissal of so much human knowledge is crystallized that the Earth might be flat. It’s just saying, everyone we came before me is a dumbass and that’s wrong,” he says. “The passion, beauty, and joy – the PB&J of science – is you can do it for yourself. It’s not man, woman. It’s not recently from Africa, recently from Europe. It’s true for everyone—the Earth goes around the sun, the Earth is a ball.”

“And if you believe the flat Earth, go to the freaking edge, and take a picture. Post it on the ‘Gram.”
