Encoding Cosmological Futures with Conformal Structures |
Abstract |
We define the new conformal frameworks of an anisotropic future endless universe and an anisotropic future singularity. Both new definitions are motivated by quiescent cosmology and the Weyl curvature hypothesis (WCH), which previously only possessed a framework for a possible classical initial state of the universe, namely the isotropic singularity. We devise a framework which also encodes appropriate cosmological futures. It is not restricted to the ideas of quiescent cosmology and the WCH, however. The new irregular, degenerate conformal structures differ significantly from those of the isotropic singularity. We discuss some of the implications of the new definitions, as well as the relation to the somewhat dual dynamical systems approach. |
