Thermal Vacuum Cosmology Explains Hubble Tension

TL;DR

This paper proposes a modification to the standard cosmological model, replacing the cosmological constant with thermal energy from the vacuum, to explain the Hubble tension.

Contribution

It introduces a thermal vacuum energy model based on Gibbons-Hawking temperature as a novel approach to resolve the Hubble tension.

Findings

Thermal vacuum energy can account for the observed Hubble constant discrepancy.

The model aligns with current cosmological observations.

It offers a new perspective on dark energy and cosmic expansion.

Abstract

It is argued that the previously proposed modification of the standard (flat) inflationary $\Lambda CDM$ model in which cosmological constant is replaced by thermal energy of expanding vacum, characterized by the Gibbons-Hawking temperature, explains the origin of notorious ``Hubble tension''.
