Cool stuff. Inspired by [1], our brains observe by taking a measurement, which collapses the billiard ball's color to be red, "instantaneous velocity."

While otherwise unattended, the billiard ball only has metadata about its original color, but is otherwise every color and no color (to us). The physics are only computed separate from maximal energy conservation.
