Finite Matter Resolution of the Cosmological Entropy Problem

TL;DR

This paper explores a finite-mass cosmological model addressing entropy bounds, discussing implications for cosmic information, matter distribution, and large-scale light trapping regions, challenging standard cosmological assumptions.

Contribution

It introduces a cosmology with finite total mass and a delta function matter density at the big bang, providing a novel approach to the entropy problem.

Findings

Entropy bounds constrain the model parameters.

The model suggests a diffusing matter density post-big bang.

Discussion of cosmic information and light trapping regions.

Abstract

We discuss how entropy bounds, which are not respected in the standard cosmology, constrain the parameters of a previously suggested cosmology with a finite total mass. In that alternative cosmology the matter density was postulated to be a spatial delta function at the time of the big bang thereafter diffusing rapidly outward with constant total mass. Also discussed here are some related issues including the cosmic onion question, the information content of the universe, and the question of whether light trapping regions exist on a cosmic scale.
