> But there is a problem with identifying entropy as the driving force behind the arrow of time. For this to be true, the universe must have started out in a very low entropy state. The puzzle is: why?
It's interesting that simplicity is the goal everywhere else in science, but it's bad when it comes to the initial state of the universe. After all, having a lot of neg-entropy is just another way of saying "takes very little information to describe". The fact that the initial state is surprisingly simple to us is oxymoronic in a way.
