Holography, Dark Energy and Entropy of Large Cosmic Structures

TL;DR

This paper explores how dark energy influences the entropy of large cosmic structures, suggesting a holographic principle similar to black holes, where surface properties encode the system's degrees of freedom.

Contribution

It proposes that dark energy constrains cosmic structures' entropy, extending the holographic principle beyond black holes to large-scale cosmic objects.

Findings

Dark energy imposes entropy bounds on cosmic structures

Holographic principle may apply to large-scale structures

Entropy related to surface area of cosmic objects

Abstract

As is well known, black hole entropy is proportional to the area of the horizon suggesting a holographic principle wherein all degrees of freedom contributing to the entropy reside on the surface. In this note, we point out that large scale dark energy (such as a cosmological constant) constraining cosmic structures can imply a similar situation for the entropy of a hierarchy of such objects.
