-- Rapper B.o.B really isn't letting go of this "the Earth is flat" idea.
After Tyson kindly explained to the "Airplanes" singer why his reasoning was Medieval and downright wrong, B.o.B fired back with a track called "Flatline" sampling a speech from the astrophysicist talking about the formation of the Earth, along with raps from B.o.B about a number of conspiracy theories.
Clearly Tyson wasn't getting through to the rapper on Twitter, so he released his own track this afternoon called "Flat to Fact."
"He learned the game from Carl Sagan/You can never check him/ You say the Earth is flat and then you try to disrespect him," the song begins.
Here is where it gets really meta. There are of course conspiracy theories abound on Twitter about B.o.B's belief of the conspiracy theory, with some speculating he's simply looking for attention.
