HIP-HOP Neil deGrasse Tyson Responds to B.o.B Diss Track with Drake-Referencing 'Flat to Fact'

A new development in the beef no one saw coming: Astrophysicist Neil deGrasse Tyson has issued a response to B.o.B's diss called (wait for it) "Flat to Fact" -- and yes, it references Drake's "Back to Back."

While Tyson admitted on Twitter that he didn't do the rapping, he recruited his own nephew, who just so happens to be a rapper, to fire the shots for him.

"I'm bringing facts to combat a silly theory because B.o.B has gotta know the planet is a sphere," the MC spits.

The record comes after Bobby Ray challenged NGT and all of the Internet that the Earth was flat. "A lot of people are turned off by the phrase "flat earth" ... but there's no way u can see all the evidence and not know... grow up," the rapper tweeted.

Dr. Tyson also appears on the track, providing the track's bookends with live readings of his previous tweets to B.o.B.

"Flat Earth is a problem only when people in charge think that way. No law stops you from regressively basking in it," he says before wrapping with, "Duude -- to be clear: Being five centuries regressed in your reasoning doesn’t mean we all can’t still like your music."
