B.o.B has been waging war against facts, but his flat earth theory sadly isn’t catching on as well as he’d hope. Neil deGrasse Tyson tried to educate the rapper on Twitter.

@bobatl Flat Earth is a problem only when people in charge think that way. No law stops you from regressively basking in it.

@bobatl Duude — to be clear: Being five centuries regressed in your reasoning doesn’t mean we all can’t still like your music

And then B.o.B took the high road and made a diss track, which was well, flat.

And then Tyson delivered him his L for the season with this banger courtesy of his nephew Mr. Tyson:

Here, hold my edges.

Yo @bobatl. The world isn’t flat, fam.

*And another rapper is willing to suspend his belief in science too for a rap rumble with Tyson.

I want in on this. I don’t believe in gravity. Come at me.
