[QUOTE="quad, post: 16605581, member: 17952"] Space is curved by the sun because of it's mass and gravity. Replace the sun with a little rock and boom space is not curved as much. And the Earth spins off into the galaxy along with all the other planets lol! Maybe Jupiter will keep them bound to the Solar System?
