B.o.B Vs. Neil deGrasse Tyson

What you need to know about hip hop’s strangest feud.

Yes, your favorite astrophysicist is in a hip hop beef.  After rapper B.o.B started tweeting what he believed to be evidence that the world is flat, Neil deGrasse Tyson stepped in to debunk the ill-advised theory. Outraged, B.o.B released a diss track in which he alleges that deGrasse Tyson is paid to propagate a round earth conspiracy.

"Neil Tyson need to loosen up his vest. They probably write that man one hell of a check," B.o.B raps.

Refusing to back down from a challenge, deGrasse Tyson responded with a diss track of his very own. With the help of friend who can rap and a sample of Drake’s diss track “Back to Back” he set the record straight with a track entitled “Flat to Fact.” Check out the video below for the full story.
