It all started Sunday when rapper-singer B.o.B. took to Twitter to preach the truth as he sees it. He wanted the world to know that the Earth is flat, despite centuries of evidence to the contrary.
The cities in the background are approx. 16miles apart... where is the curve ? please explain this pic.twitter.com/YCJVBdOWX7— B.o.B (@bobatl) January 25, 2016
@bobatl Polaris is gone by 1.5 deg S. Latitude. You've never been south of Earth's Equator, or if so, you've never looked up.— Neil deGrasse Tyson (@neiltyson) January 25, 2016
@bobatl Flat Earth is a problem only when people in charge think that way. No law stops you from regressively basking in it.— Neil deGrasse Tyson (@neiltyson) January 25, 2016
@bobatl Earth's curve indeed blocks 150 (not 170) ft of Manhattan. But most buildings in midtown are waaay taller than that.— Neil deGrasse Tyson (@neiltyson) January 25, 2016
Finally, B.o.B. deployed a new tactic to make the case that the Earth is flat, via a new song. The track entitled "Flatline" includes quotes from Tyson and takes a direct hit at him: "Aye, Neil Tyson need to loosen up his vest/They'll probably write that man one hell of a check." (Warning: Some of the language is not suitable for kids.)
The rapper claims it's not a publicity stunt, though it's certainly succeeding in getting him in the public eye.
Amazingly, Tyson escalated the rap battle with a post of his own. "As an astrophysicist I don't rap, but I know people who do," he wrote. The track includes lines like: "The ignorance you're spitting helps keep people enslaved -- I mean mentally." Ouch.
Despite it all, Tyson suggested he's something of a B.o.B. fan -- of the music, anyway.
@bobatl Duude - to be clear: Being five centuries regressed in your reasoning doesn't mean we all can't still like your music— Neil deGrasse Tyson (@neiltyson) January 25, 2016
