Two months after the fundraiser was posted, B.o.B had reached $6,883 of his $1 million goal, the first thousand of which he donated himself, according to his GoFundMe page. Flat-Earthers, of course, don't believe in the Earth's curvature (which, for the record, becomes visible to the human eye at about 35,000 feet (11,000 meters) elevation, but only given at least a 60-degree field of view, according to a 2008 paper, making it hard to detect from a typical passenger airliner window). B.o.B raised his profile further this year with an attempt to crowdfund his own rocket launch to carry a camera into space to look for the curvature of the Earth.
The rapper B.o.B, also known as Bobby Ray Simmons Jr., is famous for having gotten into a Twitter fight with physicist Neil deGrasse Tyson over whether the Earth is round.
