Which is the ontology of Dark Matter and Dark Energy?

TL;DR

This paper explores the fundamental nature of dark matter and dark energy by analyzing their possible ontological status within the framework of Poincaré group representations and quantum numbers, suggesting some candidates and the need for reclassification.

Contribution

It proposes a novel ontological framework for dark components based on irreducible Poincaré group representations and quantum numbers, challenging traditional views.

Findings

Certain dark matter candidates can be associated with specific Poincaré representations.

Some dark energy phenomena may require reclassification within this framework.

The approach offers a new perspective on the ontology of unseen universe components.

Abstract

We adopt in this work the idea that the building blocks of the visible Universe belong to a class of the irreducible representations of the Poincare group of transformations (the "things") endowed with classificatory quantum numbers ("the properties"). After a discussion of this fundamentality, the question of the nature of both "dark" components of the Universe which are deemed necessary, but have not been observed, is analyzed within this context. We broadly discuss the ontology of dark matter/dark energy in relation to the irreducible representations of the Poincar\'e group + quantum numbers, pointing out some cases in which the candidates can be associated to them, and others for which a reclassification of both the dark and visible (ordinary) components would be needed.
