These are excerpts and elaborations from my book "The Nature of Consciousness"
Entropy was low at the beginning (at the Big Bang) and has since been increasing. The destiny of the universe is, apparently, to expand forever until it will be, for all practical purposes, empty, i.e. it will have reached its maximum entropy and a state of permanent equilibrium. Black holes, in particular, have a lot of entropy (the one black hole that dwells in the center of our galaxy has 100 times more entropy than the whole observable universe).
The US physicist Sean Carroll hypothyzed ("Spontaneous Inflation and the Origin of the Arrow of Time", 2004) that the Big Bang may not be the beginning of the universe but merely a state of transition from decreasing entropy to increasing entropy. He noticed that space is not empty because of the very "dark energy" that caused its expansion. This energy causes quantum fluctuations that can create baby universes. The intriguing feature of this scenario is that one can play the universe in both directions of time: there is no arrow of time.
