Earth is ポルノグラフィティ オフィシャル サイトround. I know it. You know it. Bill Nye knows it.

But still, in 2017, many flat Earth truthers still are denying what has been known as scientific fact for centuries.

They draw in a famous crowd. Several N.B.A. stars (including Cleveland Cavaliers guard Kyrie Irving) have openly voiced their conspiracies. Now, rapper B.o.B. is using his public platform to prove his suspicions about the existence of the "curve" once and for all.

Bobby Simmons Jr. (better known as B.o.B.) launched a GoFundMe page called "Show BoB the Curve" on Thursday. In a video on the page, he calls himself "Flat Earth B.o.B." and explains that he wants to send as many satellites as he can into orbit to "find the curve." The rapper tweeted a link to the fundraising page in hopes of drumming up some support.

It looks as if B.o.B. got the idea from Twitter user Tim Pastoor, who tweeted an idea for how flat Earth truthers can "find the edge" at another user. B.o.B. retweeted and called it a "great idea."

They're always asking for an experiment they can do from home, so here's one: Crowdfund a satellite and go look for the edge.

Actually that's a great idea. 💯💯💯 https://t.co/1obtdBZocH

So far, the page has raised $225. Just a little shy of the skeptical rapper's goal of $200,000.

Eighteen individuals have donated to B.o.B.'s fund at time of writing, in amounts ranging from $5 to $50. However, not all of them seem to agree with the rapper's theories. Donor Daniel Ferguson added a comment to his donation: "Here's $5 to prove yourself wrong."

This isn't the first time B.o.B. has shared his flat Earth beliefs with the world.

In early 2016, the rapper took to Twitter to share some of his his "evidence," including several photos and assertions that the earth is indeed, flat.

Most of B.o.B's reasoning seems to be based on what he can see. He grew frustrated that some of his over two million followers told him that he wasn't high enough to see the Earth's natural curve.

This wasn't the end of B.o.B.'s public display of flat Earth trutherism. The conspiracy-driven tweets sparked a public feud between the rapper and Neil deGrasse Tyson himself.

The famous astrophysicist first fired back with some cold, hard facts. He also shared his concerns about the conspiracies.

@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.

— Neil deGrasse Tyson (@neiltyson) January 25, 2016

The rapper didn't hesitate to respond to the science legend, questioning why only NASA had photos of "the curve."

One Twitter user said he was ready for a diss track to emerge from this epic exchange.

Favorite beef of the year is @neiltyson vs @bobatl. Can't wait for the diss track!

Well, ask and you shall receive.

The Strange Clouds rapper came around later that night with the track "Flatline," which includes audio of Tyson explaining the Earth's spherical shape. In the song, B.o.B. raps, "Globalists see me as a threat, free thinking got the world at my neck."

He calls out the renowned scientist directly, saying, "Neil Tyson need to loosen his vest, they probably write that man one hell of a check." And, once again, he references his skepticism about his view of the horizon (and about science itself): "I see only good things on the horizon, that's probably why the horizon is always rising, indoctrinated in a cult called science and graduated to a club full of liars."

But Tyson wasn't going to let him get the last word. The Cosmos host enlisted the help of his nephew Stephen Tyson to clap back with his own diss-filled track.

The Notorious N.D.T. quotes his own tweet to B.o.B. on the track, "Flat to Fact." He leaves the rest of the rapping to his nephew who goes after the flat Earth theorist directly: "I'm bringing facts to combat a silly theory/Because B.o.B. has gotta know the planet is a sphere, G."

Hopefully this GoFundMe will show B.o.B. the truth about the Earth and, more importantly, end what is perhaps one of the greatest rap battles of this generation. But until then, we can check in on B.o.B.'s "step-by-step documentation" of his mission to "find the curve."
