If you were to drop a ball, it would be easy to calculate when it will hit the ground and how much energy will be absorbed by the ground (let's assume there's no air resistance and the ball does not bounce).
If you were to then reverse time, would energy from the ground gather rapidly toward the location of the ball, creating a powerful but microscopic impulse capable of launching the ball to its original height?
If the answer is yes, then the time reversed system should in fact be deterministic.
If the answer is no, then there could not possibly be any way to predict when the ball will bounce or how high it could go. The system would not be deterministic.
Which result is closer to reality?
