According to classical physics, the universe could be imagined as a giant billiards table. An indeterminate number of years ago, some great force broke the ball rack with a giant pool cue. Since then, the billiard balls — the particles that make up the stars and you and me and all the planets we can see — have been in motion, bouncing off of one another according to a strict set of physical laws. Their behavior is predictable. If you were sufficiently wise and sufficiently skilled in math, you could tally together the size, speed, composition, location, and trajectory of every billiard ball in the universe, all the way back to the Big Break or as far into the...
