Identification of All Dark Matter as Black Holes

TL;DR

This paper proposes that all dark matter in the universe consists of black holes, based on entropy considerations, suggesting a natural explanation consistent with statistical mechanics.

Contribution

It introduces the idea that all dark matter can be identified as black holes using entropy calculations, providing a new perspective on dark matter composition.

Findings

Most of the universe's entropy is from black holes.

Dark matter's energy is primarily non-baryonic and dark energy dominates.

All dark matter could be explained as black holes based on entropy analysis.

Abstract

For the universe I use dimensionless entropy $S/k = \ln \Omega$ for which the most convenient unit is the googol ($10^{100}$) and identify all dark matter as black holes whereupon the present entropy is about a thousand googols. 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 $(1 - 10^{-15})$, from black holes and only $10^{-15}$ from everything else. This identification of all dark matter as black holes is natural in statistical mechanics.
