Time-Symmetrization and Isotropization of Stiff-Fluid Kantowski-Sachs Universes
arXiv:gr-qc/9510064 · doi:10.1007/BF00640199
Abstract
It is shown that growing-entropy stiff-fluid Kantowski-Sachs universes become time-symmetric (if they start with time-asymmetric phase) and isotropize. Isotropization happens without any inflationary era during the evolution since there is no cosmological term here. It seems that this approach is an alternative to inflation since the universe gets bigger and bigger approaching 'flatness'.
