Toward a solution of the coincidence problem

TL;DR

This paper explores the coincidence problem in cosmology, proposing that expressing the Hubble rate as a function of dark matter and dark energy densities could lead to better understanding or solving this cosmic puzzle.

Contribution

It introduces a novel approach to address the coincidence problem by linking the Hubble rate to the density ratio of dark matter and dark energy.

Findings

Proposes expressing the Hubble rate as a function of density ratios.

Suggests observational determination of this relationship through redshift data.

Aims to improve understanding of late cosmic acceleration.

Abstract

The coincidence problem of late cosmic acceleration constitutes a serious riddle with regard to our understanding of the evolution of the Universe. Here we argue that this problem may someday be solved -or better understood- by expressing the Hubble expansion rate as a function of the ratio of densities (dark matter/dark energy) and observationally determining the said rate in terms of the redshift.
