There are a lot of fierce, even uncomfortable debates happening in entertainment world now, from the totally not-OK gender disparity in pay to what to do about the diversity problem.

Neil deGrasse Tyson defends Scientology: Christianity, other Religions are just as crazy

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.
