It's unlikely that anyone expected B.o.B. and Neil DeGrasse Tyson to be going head to head in 2016. After the rapper shared a stream of tweets insisting that the earth is flat—"A lot of people are turned off by the phrase 'flat earth'... but there's no way u can see all the evidence and not know"—Tyson responded yesterday with a pithy dismissal: "Being five centuries regressed in your reasoning doesn’t mean we all can’t still like your music."
B.o.B. has now called the physicist out in a track called "Flatline." Freethinking got the world at my neck, he raps. Neil Tyson gotta loosen up his vest/ They probly write that man one hell of a check/ I'm over here on this side of town/ Come on over over over over here and try to clown/ I will never pipe down.
Other key lines include: Use your common sense, why is NASA part of the Department of Defense, and Indoctrinated in a cult called science/ And graduated to a club full of liars/ Heliocentrism... fuck you and your team, you can sit on the bench with 'em.
Presumably Tyson is working on a response at this very moment.
Update, 1/26/2016, 4:40 p.m.: Tyson tweeted a link to a B.o.B. diss track.
Tyson has responded to B.o.B.'s "Flatline" with a song of his own—kind of. "As an astrophysicist, I don't rap, but I know people who do," he wrote on Twitter. Then he shared "Flat To Fact," which borrows the instrumental from Drake's "Back To Back" and features rapping from Tyson's nephew.
