Rapper B.o.B declared to his followers yesterday (January 25) that he subscribes to the conspiracy theory stating the Earth is actually flat, not round. Scientist and renowned tweeter Neil deGrasse Tyson set him straight with a string of posts, ultimately declaring that whatever B.o.B's archaic stance on the issue may be, he still digs his music.

Naturally, B.o.B has since responded to Tyson's tweets with a diss track called “Flatline,” in which he not only mentions the scientist by name (“Neil Tyson need to loosen up his vest / They’ll probably write that man one hell of a check”), but also samples one of his lectures at length.

The track continues, as B.o.B injects various conspiracy theories like reptilian people (“Now the mirror lizard’s breath got the clones scared cuz / Woo, use your, use your common sense / Why is NASA part of the department of defense?”) and bizarrely mentions Holocaust denier David Irving (“Do your research on David Irving / Stalin was way worse than Hitler / That’s why the POTUS gotta wear a kippah”). Listen to the full track above.

Not one to back down, Tyson responded with his own song called "Flat to Fact," (a play on Drake's Meek Mill diss track called "Back to Back") created by his nephew who raps under the name (wait for it) TYSON. Check that song out below and let us know whose side you're on in this science-based debate.
