Rapper B.o.B released a diss track, in which he defends his belief the Earth is flat.
The artist began purporting this claim over the weekend with a series of tweets citing observations related to perception, visibility and his idea of logic.
He questioned why there is no curve in the horizon, why New Jersey can be seen from Philadelphia and why planes don't fly into space when they go straight.
Then, astrophysicist and science communicator Neil deGrasse Tyson took to Twitter to refute B.o.B's claims by way of established scientific evidence.
B.o.B responded earlier today in the form of a song called "Flatline," in reference to the apparent lack of curvature in the horizon, Vulture reports.
The track discusses the outrage B.o.B triggered for his "free thinking," as well as his distrust of NASA and the government in general.
