Neil deGrasse Tyson's rapping nephew dropped a B.o.B. Flat Earth diss track. It's not good.

First, rapper B.o.B came out of the Flat Earth closet and declared to the world that he believes that the Earth, like time, is actually a flat circle. Then, Neil deGrasse Tyson tried to explain to him that science has proved that the Earth is actually spherical in nature. B.o.B disagreed and shot back with a diss track.

Now, Tyson’s nephew, indie rapper TYSON, has thrown his hat into this weird, weird ring with a response track titled “Flat To Fact,” a riff on Drake’s diss track to Meek Mill “Back to Back.”

It is…it is not good. But, it is scientifically accurate!

Your move, B.o.B. The Great Flat Earth Rap Battle of 2016 has begun.
