A Possible Mechanical Explanation For Gravity.

[Little Bang]

Suppose we could make a sphere out of some mythical material that is totally non-elastic. Inside the sphere we place six balls made of the same material such that the balls almost touch the sphere but not quite. The sphere is located somewhere out in space where gravity is as close to zero as possible. We shake the sphere to start the balls bouncing around inside. Each ball has the same mass and inside of each ball is a clock that we can observe. Now we use the clock of each ball to measure it's momentum just before it collides with another ball and obviously we find that the momentum of each ball is identical. Next we move our sphere close to the edge of a black holes event horizon. If we calculate the momentum of a ball bouncing toward the EH we find that because it's clock slows down as compared to a ball bouncing away from the EH that it's momentum is greater. The total momentum of the balls will always be greater toward the EH. Instead of balls we could be talking about atoms. Can someone show me why this does not imply that gravity is just an artifact of time dilation?
