Last week, Rapper B.o.B released a series of tweets in which he claimed the Earth with flat, and not round like scientist previously suggested. B.o.B. started by tweeting a photo of the skyline with the caption “The cities in the background are approx. 16miles apart… where is the curve ? please explain this.” Even renowned astrophysicist, Neil deGrasse Tyson, could not convince B.o.B that the Earth was flat when he tweeted “@bobatl Earth’s curve indeed blocks 150 (not 170) ft of Manhattan. But most buildings in midtown are waaay taller than that.” After B.o.B continued to tweet thing along the lines of, “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… grow up,” and “You can regurgitate force fed information all day… still doesn’t change physics.” Tyson had had it and tweeted “Duude — to be clear: Being five centuries regressed in your reasoning doesn’t mean we all can’t still like your music.”

The very next day B.o.B released a song by the title “Flat Line (feat. Neil Tyson),” where he rapped about more flat Earth conspiracy theories, said “Aye, Neil Tyson need to loosen up his vest/ They’ll probably write that man one [heck] of a check,” and included a brief exert from a Neil Tyson speech. Following the release of “Flat Line,” Tyson tweeted the Soundcloud link to rapper Tyson’s (no relation) song “Flat to Fact (Feat. Neil deGrasse Tyson)” in which the rapper disputes the “facts” B.o.B made earlier. Rapper Tyson’s song also included scientist Tyson reading the diss tweets he had made the day before.
