Entropy is increasing. I am accepting this statement as a fact which I don't know how to verify by experiment. Entropy, as I understand, is related to number of arrangement of objects found in a given system. The more objects there are, the higher is the entropy. For a universe of just one object and if the object is not spinning and shape like a sphere, then the number of arrangement of this object in the universe is 1. This is the minimum for a quantum universe. Obviously, the physical universe is full of many objects: planets, stars, galaxies, interstellar clouds and dust. So there are many possible arrangements for these objects. The entropy should have a large value. But out of these random chaotic arrangements, some semblance of order emerge and I can pressume that this order should lower the value of entropy. Does this emergence of order gave a reason for the universe to expand for entropy to keep on increasing? For black holes, entropy is at a maximum and according to Bekenstein and Hawking, entropy is dependent on the surface area of the black hole not its volume. Relatively speaking, when the universe expands the relative size of an object should decrease toward becoming a point-object and eventually all objects would become of the same size as the spacetime point (either quantized or continuous). So the maximum entropy of the universe is at the time when all objects turn back to the identity of a point of spacetime ( there should be an infinite number of arrangement for an infinite points of spacetime).
