Neil DeGrasse Tyson Drops the Mic on B.o.B on "The Nightly Show"

In the latest escalation of their war of words, astrophysicist Neil DeGrasse Tyson appeared on "The Nightly Show" to rebuke B.o.B's insistence that the Earth is flat. After host Larry Wilmore initated the "science emergency defense program," Tyson showed up to deliver a quick lesson on why we perceive the Earth as flat when we stand on it, despite its roundness, as well as shame B.o.B for his unscientific approach. After quoting Isaac Newton, Tyson said: "That's right, Bo.B, when you stand on the shoulders of those who came before, you might just see far enough to realize the Earth isn't fucking flat." He also demonstrated how gravity works by fittingly dropping the mic. Watch his appearance below, via Vulture.

Here's the backstory: Earlier this week, B.o.B went on a Twitter monologue about how the Earth is flat, prompting Tyson to respond to him with science. B.o.B then released "Flatline," a song that dissed Tyson as well as promoted several other conspiracy theories (and the work of Holocaust denier David Irving). After that, Tyson's nephew dropped his own diss track, "Flat to Fact."
