"I'm starting this GoFundMe because I would like to send one, if not multiple satellites, as far into space as I can, or into orbit as I can, to find the curve," the rapper says in a video posted on the crowdfunding website. The campaign is currently trending on the site.
Some of those who have donated to the campaign have expressed support for the rapper.
"I know the earth is round, but am willing to donate for educational purposes," writes one person who donated $10.
"I am glad you are not afraid to ask, "What if". If it were not for people like you, nothing would be discovered or corrected," writes another who donated $20.
Plenty of others, meanwhile, are mocking him.
"I'm making a donation just so I can see you humiliate yourself. I think Bill Nye and Neil deGrasse Tyson should follow my lead as well! #EducationMatters," comments another.
One person has even started a crowdfunding campaign to send the rapper himself into space.
Last year, B.o.B had a bizarre Twitter spat with astrophysicist Neil DeGrasse Tyson which ended with the rapper releasing a "diss track" called "Flatline." Click for more trending news
