Following a two day Twitter-thon in which he supplied photos and text backing up a theory that the earth is flat, B.o.B came through late Monday night (Jan. 25) with a new track reinforcing his claims. "Flatline" uses audio of world-renowned astrophysicist Neil deGrasse Tyson, who jumped into the rapper's Twitter mentions yesterday, disproving his theory, to lend credence to B.o.B's assertion.

While Tyson wrote yesterday, "Duude — to be clear: Being five centuries regressed in your reasoning doesn’t mean we all can’t still like your music,” the audio clip shows him confirming that the earth is an oblate spheroid and pear-shaped.

While deGrasse Tyson would likely contest the context of his segmented remarks and dispute the end which B.o.B uses them to prove, the rapper does manage to put together a focused, bar-heavy effort that at the very least proves his own grasp on the messages he's sending out. Throughout the song, he raps, "Globalists see me as a threat, free thinking got the world at my neck," "Neil Tyson need to loosen his vest, they probably write that man on hell of check" and "I see only good things on the horizon, that’s probably why the horizon is always rising, indoctrinated in a cult called science and graduated to a club full of liars."

B.o.B added to his Twitter treatise with a pair of messages pointed at the response given to him by media outlets on Monday. "Since all mass media wants to make me look crazy and drag me through the mud... make sure you mention the cloning centers I talked about," he wrote. And later: "here n america, you can be anything, worship anything, & believe anything... EXCEPT the earth not being round... they'll hang u 4 that 1."

Tyson likely didn't know the depth of his involvement here in what has become the first patently bizarre rap-related feud of the new year. If Tyson responds or B.o.B continues to plant his flat earth flag deeper, we will update this story accordingly.
