The International Space Station

If I have a hole straight from one end of the earth to the other, east to west, south to north and I jumped in that hole. Would I go all the way through to the other side of the earth or would I stop in the middle because of gravity pushing me? In the middle you would reach the same speed as the International Space Station. It's called simple harmonic motion and the time required is about 42 to 45 minutes. We've got Ari on the line with his question for Dr. Carl. Next up we have Dr. Kane.
