For the universe I use dimensionless entropy S/k = ln Ω for which the most convenient unit is the googol (10{sup 100}) and take all dark matter as black holes whereupon the present entropy is about a thousand googols independently of whether dark energy possesses entropy. While the energy of the universe has been established to be about 0.04 baryons, 0.24 dark matter and 0.72 dark energy, the cosmological entropy is almost entirely, about (1−10{sup −15}), from black holes and only 10{sup −15} from everything else. This identification of all dark matter as black holes is natural in statistical mechanics.
