A Local View of the Observable Universe
Physical Review Letters
We present results on the non-linear dynamics of inhomogeneous cosmological models with irrotational dust and a positive cosmological constant, considering, in particular, a wide class with vanishing magnetic Weyl tensor. For those patches of the universe that do not recollapse to a singularity we find a unique attractor, representing a de Sitter vacuum phase. For the (re-)collapsing regions we find a family of (Kasner) attractors, so that generically these regions fall in spindle-likedoi:10.1103/physrevlett.74.1916 pmid:10057796 fatcat:wtghccpqdnbzdcwp2pomiu6vqa
