B.o.B. is keeping up with his "world is flat" theory, which brought him plenty of attention online yesterday (January 25).
In a series of tweets, the musician laid out his beliefs and cited theories, only to have commenters challenge him. His supporters were plenty, as well, but he had one well-known challenger in Neil deGrasse Tyson.
No matter to Bobby Ray, who keeps the conversation burning with a new track "Flatline," aimed at Tyson and further pursuing his flat beliefs.
