Page "Arrow of time" Paragraph 12

If we record somebody dropping a ball that falls for a meter and stops, in reverse we will notice an unrealistic discrepancy: a ball falling upward!

But when the ball lands its kinetic energy is dispersed into sound, shock-waves and heat.

In reverse those sound waves, ground vibrations and heat will rush back into the ball, imparting enough energy to propel it upward one meter into the person's hand.

The only unrealism lies in the statistical unlikelihood that such forces could coincide to propel a ball upward into a waiting hand.
