Update | In response to B.o.B's diss track, Neil deGrasse Tyson's nephew, a rapper who goes by the name TYSON, released a diss track of his own Tuesday afternoon. Set to the beat of Drake's popular song "Back to Back"—itself an evisceration of rapper Meek Mill—it is called, naturally, "Flat to Fact."

Your move, B.o.B.

In what is quickly becoming one of the strangest celebrity beefs in recent memory, Georgia rapper B.o.B has been exchanging jabs with renowned astrophysicist and Cosmos presenter Neil deGrasse Tyson over whether the Earth is flat. B.o.B thinks it is. Tyson—being a top U.S. scientist and all—argues that it, in fact, is not.

The Twitter back-and-forth began on Sunday evening, when B.o.B tweeted the observation below to his 2.3 million followers about the lack of a perceived curve in the background of a photo.

The cities in the background are approx. 16miles apart... where is the curve ? please explain this

Since Sunday, the Carolina-born rapper has gone on a deep dive into the "Earth is flat" conspiracy, live-tweeting his findings along the way. The crux of B.o.B's argument is that to the naked eye, the planet does not appear to be curved. He argues that the widespread belief that the Earth is round is an elaborate hoax perpetrated by NASA and the Freemasons.

B.o.B is actually not the only flat Earth truther out there. There is an entire Flat Earth Society, whose mission is to "promote and initiate discussion of Flat Earth theory," which stems from "literal interpretations of Bible passages." The society sells its own merchandise and everything.

As with any good conspiracy theory, a trove of explainer videos can be found on YouTube—created by presumed basement dwellers with intermediate PowerPoint knowledge.

For Tyson, who has been known to debunk bad science in mainstream pop culture through his Twitter account—most recently that of Star Wars: The Force Awakens—the argument that the Earth is flat couldn't be a juicier softball.

@bobatl Earth's curve indeed blocks 150 (not 170) ft of Manhattan. But most buildings in midtown are waaay taller than that.

@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.

@bobatl Flat Earth is a problem only when people in charge think that way. No law stops you from regressively basking in it.

@bobatl Duude — to be clear: Being five centuries regressed in your reasoning doesn’t mean we all can’t still like your music

But B.o.B isn't having any of Tyson's science. On Monday night, the rapper took the beef to its logical conclusion by releasing a diss track aimed at Tyson and other believers in a round Earth.

Some choice excerpts:

Neil Tyson need to loosen up his vest
They'll probably write that man one hell of a check

NASA is not out of range for B.o.B's fire either.

Use your, use your common sense
Why is NASA department of defense?
They divided up the seas into thirty-three degrees
Feeding kids masonry, be careful what you read

Bars upon bars.

That's probably why the horizon is always rising
Indoctrinated in a cult called science
And graduated to a club full of liars
Heliocentrism, you were the sixth victim
Fuck you and your team, you could sit on the bench with 'em

But when it was all said and done—if it is (please, God, let it be done)—Tyson threw the hammer down an hour after B.o.B posted his diss track.

The Cosmos is knowable. When childhood curiosity persists as an adult, it inoculates against others telling you what to think
