wrong, there is no up or down in the universe, and there is simply nothing keeping the earth in place. the earth is constantly spinning at speeds up to 2,000 mph, meaning that if we were to suddenly stop, it would be absolutely devastating. the earth is also not held up by anything in this universe, it simply levitates in place. like i said, there is no up or down, so down is sideways and up is forwards. the only thing the earth it technically "standing" on is the sun's massive gravitational pull, keeping it in a stable orbit.
