 The existence of such a general gravitational entropy may provide a key to answering the question about the development of stars, galaxies, and other large-scale structure in the universe, as well as the puzzle about the fact that the very early universe seems prima facie to have been already a state of very high  entropy.[20]  Just as the thermodynamical behavior of ordinary matter picks out a preferred direction in time, the idea goes, so does the way gravity tends to shape the evolution of matter on cosmological scales, and, moreover, it picks out the very same direction in time. If one could show that the extremely homogeneous conditions of the very early universe was a state of low gravitational entropy, and that the current inhomogeneous clumping of matter into stars, galaxies, etc., is a state of high gravitational entropy, and that the difference in gravitational entropy is enough to counterbalance the decrease in the entropy of ordinary matter as the universe evolved from homogeneity to clumpiness, then one would have saved the Second Law by replacing it with the Generalized Second Law. And that is exactly what many physicists today think is the solution to our problem: how to reconcile the appearance of an early state of the universe of high entropy with the demanded universal validity of the Second Law.
