In what feels like a throwback to Insane Clown Posse thinking magnets are magic, rapper B.o.B took to Twitter to proclaim he doesn’t believe the world is round.

(Maybe this is more of a throwback to the Middle Ages, but who cares about eras when hashtags weren’t a thing?)

While many a celeb has spout an incoherent tweet or two, B.o.B seems pretty adamant that the world is indeed flat.

Maybe we can let this following Tweet slide as it involved the astute observation of the lack of curvature when gazing out on the horizon.

 

  But… then it got weird. B.o.B thinks NASA is keeping the truth from us about the world actually being flat.  

So like any vigilant astrophysicist, Neil DeGrasse Tyson addressed B.o.B on Twitter saying, “Flat Earth is a problem only when people in charge think that way. No law stops you from regressively basking in it.” Tyson added, “Duude—to be clear: Being five centuries regressed in your reasoning doesn’t mean we all can’t still like your music.”

However, the spat soon turned into an all out rap battle. B.o.B released a song called “Flatline”. Unfortunately, the track is no longer available on SoundCloud, but here are some of the lyrics:

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
Aye, Neil Tyson need to loosen up his vest
They’ll probably write that man one hell of a check

But wait. There’s more:

Heliocentrism, you were the sixth victim
Fuck you and your team, you could sit on the bench with ‘em
But before you try to curve it, do your research on David Irving
Stalin was way worse than Hitler
That’s why the POTUS gotta wear a Kipper
I’m a man first ‘fore an artist
Get a lawyer, look up Doctor Richard

Yes, B.o.B name-checks Holocaust denier David Irving in the baffling lyrics.

Whether or not there’s any rationality behind B.o.B’s actions, Tyson is steadfast in the power of knowledge and in return released his own diss track, Flat to Fact.

Take a listen:

Hopefully Tyson’s rap finally puts a flatline in B.o.B.’s theories.
