Holographic principle and large scale structure in the universe

TL;DR

This paper develops a model of the universe's large scale structure using the holographic principle, identifying self-similar levels from superclusters to star clusters, consistent with cosmological observations.

Contribution

It extends the holographic principle to describe the universe's large scale structure and identifies self-similar levels based on gravitational energy considerations.

Findings

Stellar systems formed around redshift 62.

Self-similar structures appeared at redshift 4.

Relaxation times vary with structure mass, being less than the universe's age for star clusters.

Abstract

A reasonable representation of large scale structure, in a closed universe so large it's nearly flat, can be developed by extending the holographic principle and assuming the bits of information describing the distribution of matter density in the universe remain in thermal equilibrium with the cosmic microwave background radiation. The analysis identifies three levels of self-similar large scale structure, corresponding to superclusters, galaxies, and star clusters, between today's observable universe and stellar systems. The self-similarity arises because, according to the virial theorem, the average gravitational potential energy per unit volume in each structural level is the same and depends only on the gravitational constant. The analysis indicates stellar systems first formed at z\approx62, consistent with the findings of Naoz et al, and self-similar large scale structures began to appear at redshift z\approx4. It outlines general features of development of self-similar large scale structures at redshift z<4. The analysis is consistent with observations for angular momentum of large scale structures as a function of mass, and average speed of substructures within large scale structures. The analysis also indicates relaxation times for star clusters are generally less than the age of the universe and relaxation times for more massive structures are greater than the age of the universe.
