Yesterday B.o.B. posted dozens of tweets about the Earth being flat, which were detested by astrophysicist Neil deGrasse Tyson and thousands of his Twitter followers. The Columbia University grad listed off scientific facts to B.o.B, directly, ending his lesson with "Duude — to be clear: Being five centuries regressed in your reasoning doesn't mean we all can't still like your music."

Naturally, B.o.B. didn't take too kind to Tyson's tweets (or scientific reasoning, for that matter) and dropped a diss track at midnight entitled "Flatline." "Globalists see me as a threat, free thinking got the world at my neck / Hah, am I paranoid? Picture Malcolm X in a room full of pigs, trying not to bust a sweat," he raps. "Aye, Neil Tyson need to loosen up his vest - they'll probably write that man one hell of a check." He then goes on to make claims about NASA and includes an audio clip of Tyson at the end, which you can listen to above.
