 Moon Experiment (Posted on 2004-11-22)
Assume the moon is a perfect sphere and a straight tunnel has been drilled through the center. How long would it take a 1kg ball dropped from one end of the tunnel to reach the center? Ignore all resistances.

If a second 1kg ball is dropped 10 seconds after the first one, when and where in the tunnel would they first meet?

Idealized Moon Stats:
- Diameter: 3480 kilometers
- Mass: 7.38x10^22 kilograms (uniform density)

the ball will stop in the center of the moon becuase that is where the moons gravity originates from. If you drilled a hole through the center, it will fall to the center and then stop. that is gravity
