Assume you could make a tunnel through the center of the earth so you could go from one side of the planet to the other. Assume that air resistance is very minimal and that you don’t burn up due to the intense heat and radiation; describe your fall through the tunnel if you jumped into the hole on one side of the planet. Our physics Professor asked us this bizarre question and I have been pondering it ever since. Wouldn't the answer depend on the radius of the hole? My own odd logic thinks that you would be able to travel through the hole without any resistance, in fact, since there are large masses to the sides of you (and therefore gravity pulling from two sides), you would levitate from the sides which would put you right in the center of the hole. Anyone have any ideas? Thanks in advance everyone!
