Conformal formulation of cosmological futures

TL;DR

This paper introduces a new conformal framework for describing anisotropic cosmological futures, expanding the theoretical tools available for understanding the universe's long-term evolution beyond isotropic models.

Contribution

It develops a novel conformal formulation for anisotropic future states of the universe, extending the Weyl curvature hypothesis to include anisotropic singularities and endless universes.

Extends conformal framework beyond isotropic models

Abstract

We summarise the new conformal framework of an Anisotropic Future Endless Universe and an Anisotropic Future Singularity. Both new definitions are motivated by, but not restricted to quiescent cosmology and the Weyl curvature hypothesis, which previously only possessed a framework for a classical initial state of the universe, namely the Isotropic Singularity. Some of the features of the framework are briefly discussed.
