Dark matter and dark energy in combinatorial quantum gravity

TL;DR

This paper proposes that dark matter and dark energy naturally emerge from a combinatorial quantum gravity model, with dark energy linked to ground-state curvature and dark matter to space-time allotropes.

Contribution

It introduces a novel combinatorial quantum gravity framework where dark matter and dark energy are explained as inherent features of the model's discrete space-time structure.

Findings

Dark energy originates from ground-state curvature at finite coupling.

Dark matter results from allotropy in the discrete space-time structure.

The model suggests stable space-time 'crystals' with metastable states as dark matter candidates.

Abstract

We point out that dark matter and dark energy arise naturally in a recently proposed model of combinatorial quantum gravity. Dark energy is due to the ground-state curvature at finite coupling, dark matter arises from allotropy in the discrete structure of space-time. The stable structure of the space-time "crystal" represents the curved background, the coexisting metastable allotropes of higher curvature and energy are natural candidates for dark matter.
