but, how would a force like gravity pull you when in fact there would be a force pushing you from both sides. I don't understand how it would pull you, well I guess if you were standing up (not really standing) your head and feet would be drawn to your waist.
if you were to drill a hole through the center of the Earth and line the whole with a material that made everything stay out of the hole (The bottom line is a clear path from one side of the Earth to the other) and you fell down the hole what would happen. I would think you could not escape...
