Rapper B.o.B. and astrophysicist Neil Degrasse Tyson have been engaging in one of the more unlikely beefs of all time.

It started when B.o.B. said the world was flat. Tyson corrected him. So B.o.B. recorded a diss track targeting Tyson. Then Tyson's rapper nephew came back at B.o.B with bars.

Yesterday on the Nightly Show With Larry Wilmore, Tyson used his own words to eviscerate Bobby Ray's flat earth argument.

Tyson ends the segment with a gravity proving mic drop. But something tells us we'll still be hearing more from B.o.B on the subject of the earth's shape
