Cosmological implications of Karolyhazy uncertainty relation

TL;DR

This paper explores how the Karolyhazy uncertainty relation implies the existence of dark energy and estimates its dynamics throughout the universe's evolution, linking quantum uncertainty to cosmological phenomena.

Contribution

It provides a novel analysis of dark energy dynamics derived from the Karolyhazy relation within an effective quantum field theory framework.

Findings

Dark energy naturally emerges from the Karolyhazy relation.

The model predicts specific evolution patterns for dark energy.

Results support the relation's relevance to cosmological observations.

Abstract

Karolyhazy uncertainty relation, which can be viewed also as a relation between UV and IR scales in the framework of an effective quantum field theory satisfying a black hole entropy bound, strongly favors the existence of dark energy with its observed value. Here we estimate the dynamics of dark energy predicted by the Karolyhazy relation during the cosmological evolution of the universe.
