Recently everyone became fully aware that rapper B.o.B is a very passionate flat-Earther.
Followers of the 28-year old hip-hop star will know all about his pronouncements on the matter, having tweeted profusely about it.
"No matter how high in elevation you are...the horizon is always eye level...sorry cadets...I didn't wanna believe it either," he wrote back in 2015. "Don't believe what I say, research what I say. I'm going up against the greatest liars in history ... you've been tremendously deceived."
The rapper wears his position as king of the flat Earth with pride and now, he is taking it to the next level. B.o.B. is so convinced that the curvature of the Earth doesn't exist that he has launched a crowdfunding initiative to build his own spacecraft to conclusively prove it.
The target is $200,000 (£150,000), which seems oddly small for a spaceship, though perhaps he's going for the lawn chair tied to helium balloons that saw California man Larry Walters lifted into the stratosphere back in 1982.
Such is the absurdity of the comment, NASA astronauts, renowned the world over for knowing their shit, have replied to the musician.
Terry Virts, who at various points in his life may as well have paid rent on board the International Space Station, gave it to him straight, saying "I can save BoB a lot of money- The Earth is round. I flew around it [sic]."
His point was backed up by none other than Buzz Aldrin, the second person to walk on the moon.
He quoted Terry's tweet, adding: "I did too. It's called an orbit: the curved path of a celestial object around a star, planet, or moon."
To then hammer home the point, Scott Kelly, who commanded the International Space Station (ISS) on three expeditions and was a member of the yearlong mission to the ISS, shared a short but emphatic video.
The clip shows one full orbit of Earth...
Being as passionate as he is, this hasn't persuaded B.o.B that he might be wrong.
He took to Twitter once again to say: "People usually discourage you from doing something when they have something to hide."
On a separate note, in one of B.o.B's more popular songs, 'So Good', he actually tells a girl that they can travel 'the globe'. Odd, really.
He even once got into a Twitter spat with Neil deGrasse Tyson - which is a bit mad when you consider he's the most famous astrologist in the world - even releasing a diss track against the scientist.
