As I move away from the earth, the effect of gravity is reduced. At the earth's surface, gravity is greatest on me. Will gravity decrease if I go below ground and closer to the center of the Earth?
If I could stand at the center of the earth, wouldn't I be weightless because there is no mass at the center but the earth's mass would be all around me? Would I be pulled in all directions and blow up like a balloon?
Anybody seen any web sites that discuss this topic?
