I hope this thread doesn't levitate into that old thing about the hole through the center of the earth. What? Who me? Rule 6? You wouldn't! OK, maybe you would, so just in case, it goes like this:

Suppose there was a hole through the center of the eartr clear to the other side. Assume comfortable temperatures and pressure all the way through. We are concerned only with motion here. If you fell into the hole, aerodynamic drag would limit your speed and you would fall past the center but not all the way up to the other side. After passing center, gravity would stop working for you and would begin to work to slow you down. Somewhere short of the other side, you would slow down, stop, and then fall back the other way. After falling a shorter distance, you would pass center at a slower rate and therefore would not go as far past center. Sooner or later you would come to a stop at the center and remain there. A 4000 foot ladder would be very handy after that.

But the question is, how many times would you pass center? Further, how long would all of this take? And more important, who cares?
