Neil DeGrasse Tyson Proves Gravity, Drops Mic on Rapper B.o.B. Over Twitter Beef (Video)

The Earth is round again, astrophysicist proves on “Nightly Show,” so that settles that

Neil DeGrasse Tyson just dropped the mic on rapper B.o.B. — for real.

The beloved astrophysicist took their Twitter beef to Larry Wilmore’s “Nightly Show” on Wednesday, crushing the “Airplanes” emcee with a few on-camera physics lessons. The final one, an actual mic drop, was all about gravity. Sir Isaac Newton would have handled his hip-hop feuds in the same exact way.

“All right, listen B.o.B., once and for all,” Tyson kicked off his segment, before beginning with some apparent size and stature jokes about the artist. B.o.B. stands 5 feet 10 inches tall; Tyson is 6-foot-2.

“Small sections of large curved surfaces will always look flat to small creatures that crawl upon it,” the actual scientist said during his Comedy Central opportunity, explaining why the hip-hop artist’s online insistence that the globe is actually flat is foolish and even dangerous.

Tyson then got into the calculus and non-Euclidean geometry of the whole. This reporter could so easily explain that to you, but I don’t want to bore anybody.

We’ll just let Tyson have the last word, instead: “The Earth isn’t f–king flat,” he concluded.

B.o.B. had actually released NDT diss track “Flatline” after some 140-character back-and-forth between the two — but we think this effort by Tyson is the response that ultimately wins.
