Neil deGrasse Tyson argues with rapper B.o.B about whether Earth is flat

It turns out while we were all losing sleep over important matters like if "Making a Murderer's" filmmakers left out crucial evidence, physicist Neil deGrasse Tyson was engaged in an epic philosophical battle for the ages with rapper B.o.B. over whether the Earth is flat or round.

In a series of tweets, the "Airplanes" singer essentially declared us all fools for believing our planet is round, prompting Tyson to boldly go where no celebrity scientist has gone before: dropping basic science knowledge to a rapper over Twitter.

"Duude," Tyson wrote in one tweet, "to be clear: Being five centuries regressed in your reasoning doesn't mean we all can't still like your music."

Burn! This is the kind of rap feud we can totally get behind. See some of the exchange below.
