WebSo the answer to this conundrum is that there actually is gravity. It's not a gravity-free environment. It's just that the astronauts and the space shuttle and everything else that's in the space shuttle, it's all falling, but it's moving fast enough that it never hits the Earth. It keeps missing the Earth.
