B.o.B. has started a GoFundMe to buy satellites so he can prove the Earth is flat

The rapper ended up in a feud last year with famed astrophysicist Neil deGrasse Tyson

Last year, rapper B.o.B. officially joined the Flat-Earther club.

That's after a series of bizarre tweets claiming the world has been "tremendously deceived" and that we all needed to "grow up" and realise it, thousands of years of science be damned.

He even managed to catch the attention of famed astrophysicist Neil deGrasse Tyson, who deconstructed his theory point-by-point; B.o.B. then responded with the track "Flatline feat. Neil Tyson", with lyrics such as: "Aye, Neil Tyson need to loosen up his vest/ They'll probably write that man one hell of a check."

Not content to leave things there, the rapper's now started a GoFundMe page to prove his doubters wrong, planning to "purchase and launch multiple satellites into space" to find Earth's curve and see if the planet is actually round and not a giant flat disc as he suspects.

Earth's curve is a major point of contention for Flat-Earthers, since they believe it should be more visible to the human eye on the planet's surface; a point he tried to demonstrate by photographing two cities 16 miles apart which appear in line with each other. Of course, the answer is simply that the curvature isn't visible within such a minute distance.

B.o.B. has so far raised just under $700 of the $200,000 needed to send satellites where satellites have definitely been before, to see nothing new and witness what everyone already knows.
