Cosmological parameters from the thermodynamic model of gravity

TL;DR

This paper presents a thermodynamic gravity model that explains dark energy as collective gravitational interactions, providing estimates of cosmological parameters that align closely with observations.

Contribution

It introduces a novel thermodynamic approach to gravity that accounts for dark energy through collective interactions, differing from standard models.

Findings

Estimated dark energy density matches observations

Derived baryon and radiation densities are consistent with current data

Supports thermodynamic gravity as a viable cosmological framework

Abstract

Within our recent thermodynamic model of gravity the dark energy is identified with the energy of collective gravitational interactions of all particles in the universe, which is missing in the standard treatments. For a simple model universe composed of neutral and charged particles of identical mass we estimate the radiation, baryon and dark energy densities and obtain the values which are very close to the current cosmological observations.
