Cosmological implications of Karolyhazy uncertainty relation

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.
