Rapper and singer Bobby Ray Simmons Jr., better known as B.o.B, took to Twitter Sunday night through Monday insisting that earth is flat and providing "proof" with some photos and supposed facts, but astrophysicist Neil deGrasse Tyson shut him down with some fast facts. 

Tyson responded to some of B.o.B's tweets with corrections. In response to one that said you shouldn't be able to see the New York City skyline from Harriman State Park's Bear Mountain, Tyson tweeted that the city would be blocked if the buildings in Manhattan weren't tall enough to be seen.

Another of B.o.B.'s tweets said you shouldn't be able to see Polaris, the North Star, from the Southern hemisphere. Tyson explained that the North Star does disappear once you head south of the Equator.

Tyson added that thinking the earth is flat is "a problem only when people in charge think that way. No law stops you from regressively basking in it." And his final quip: "Duude — to be clear: Being five centuries regressed in your reasoning doesn’t mean we all can’t still like your music."

 B.o.B responded to Tyson, telling him to fly to the moon and let people see him through a telescope.
