Neil deGrasse Tyson Gave B.o.B. the Business Last Night

Neil deGrasse Tyson, America’s official keeper of popular science, has suddenly found himself embroiled in a feud with B.o.B., the rap artist who has made headlines for his staunch beliefs (and tweets) regarding the earth’s surface, which he believes is flat, and not round. Neil deGrasse Tyson does not like it when people with influence feed misinformation to the public. And so he retaliated; first with a rap, and then with an appearance on the The Nightly Show With Larry Wilmore

On the show, Tyson explained very complicated but easy-to-understand theories of non euclidean geometry to B.o.B., calmly outlining that very small things cannot see the curvature of the surface on which they crawl, simply because our perception doesn’t allow us to. He did so after handing his sandwich and jacket over to Wilmore, and ended the whole thing with a mic drop, which he prefaced by saying, “This is called gravity.”

Wilmore tweeted a highlight of Tyson’s appearance:
