Update 5 p.m. ET: Neil deGrasse Tyson's nephew, Vice reports, just responded to B.o.B's diss track with "Flat To Fact," a song that implements the most incredible "Weird Al" Yankovic-type flow. This is now, officially, lit.

Bobby Ray Simmons, Jr., known professionally as the rapper B.o.B (which actually stands for Bob), has joined the list of rapidly fading celebrities who believe the Earth is actually flat. Yesterday, he released a storm of knowledge memes on his unsuspecting 2.3 million Twitter followers that proved "once you go flat, you never go back."

Shortly afterward, Neil deGrasse Tyson—a Harvard-educated astrophysicist and cosmologist who has the soul sucking job of trying to get people to understand scientifically proven facts—chimed in to politely teach B.o.B something that humanity has known for hundreds of years.

@bobatl Earth's curve indeed blocks 150 (not 170) ft of Manhattan. But most buildings in midtown are waaay taller than that. — Neil deGrasse Tyson (@neiltyson) January 25, 2016

@bobatl Polaris is gone by 1.5 deg S. Latitude. You’ve never been south of Earth’s Equator, or if so, you've never looked up. — Neil deGrasse Tyson (@neiltyson) January 25, 2016

@bobatl Duude — to be clear: Being five centuries regressed in your reasoning doesn’t mean we all can’t still like your music — Neil deGrasse Tyson (@neiltyson) January 25, 2016

In response, B.o.B has dropped what we are fairly confident is the first-ever Neil deGrasse Tyson diss track. It's called "Flatline - feat. Neil Tyson", and at one point the rapper name-drops Holocaust denier David Irving. Enjoy.
