Penrose wrote in the Road to Reality that gravitational clumping increases the entropy of the universe. The early universe was very low in entropy because it was very smooth, with very little clumping. So, is it accurate to say that the early universe was high in entropy except for the gravitational contribution? Almost like the universe was allowed to equilibrate without gravity and then gravity was suddenly turned on? If gravity was turned off for the beginning of the universe, would this explain the low entropy of the initial universe?
