Re: [Phys-l] Arrow of Time Issue

In 1800 if I were to ask you to describe where humans came from, you would say God (if you were a good Christian man). Scientifically, we know that humans have evolved from Ardipithecus. Or if I asked you to describe the accurate quantum theory of gravity you would have no idea. The world is full of uncertainties, you just have to go out on a limb an take a chance (e.g. Einstein, Newton, Darwin, Plank)
