There are multiple petitions out there, but the frontrunner, "Do not allow Jeff Bezos to return to Earth," had collected more than 33,000 signatures by late Sunday. "Billionaires should not exist," the description read. "On Earth, or in space, but should they decide the latter they should stay there." Bezos is the founder of the space exploration company Blue Origin, which built New Shepard. The rocket is reusable and has capacity for six passengers in its capsule. "If you see the Earth from space, it changes you. It changes your relationship with this planet, with humanity. It's one Earth," Bezos said in a video posted to Instagram. Bezos isn't the only billionaire with his sights set on out-of-this-world endeavors.
