TL;DR

This paper explores how the cosmological constant emerges as a constant of integration in thermodynamic gravity models, and how it can be bounded using quantum uncertainty principles related to horizon information.

Contribution

It introduces a novel approach linking the cosmological constant to horizon information bounds within thermodynamic gravity frameworks.

Findings

Cosmological constant appears as an integration constant in thermodynamic gravity models.

The Károlyházy uncertainty relation can bound the cosmological constant.

The model connects quantum information limits to cosmological parameters.

Abstract

Within thermodynamic models of gravity, where the universe is considered as a finite ensemble of quantum particles, cosmological constant in the Einstein's equations appears as a constant of integration. Then it can be bounded using Karolyhazy uncertainty relation applied for horizon distances, as the amount of information in principle accessible to an external observer.
