jumping off the planet in reality is of course impossible, talking about the crazy sites beliefs, it would not be.
if the elevator lost control and fell down its colum, falling faster than gravity, yes you would be on the ceiling, or at least levitating.
but that argument is pointless because... well gravity is still a factor
weve all seen the video of nasa and the weightless stuff. they are on a spacecraft, the spacecraft and them are moving at a certain rate, inertia. so wouldnt it be true that if they pushed off from a surface from the spacecraft they would go flying in the opposite direction?
you know... the laws of physics, equal and opposite reaction mumbo jumbo...
so theoretically, if the planet had no gravitational pull, you could jump off the face of the earth if you were on side B of the plant and its inertia was toward that of side A
