Cosmological Anisotropy and the Cycling of Universe
Abstract
Description
In this paper, we analyze the anisotropy of the scale factor in the Kantowski-Sachs spacetime. We show that the anisotropy will not increase when the expansion rate is greater than certain values while it will increase when the expansion rate is less than that value or the Universe is contracting. It is manifested that the matter dominated and radiation dominated era favor the flat spacetime if the anisotropy does not develop significantly. The relation between the cosmological anisotropy and the red-shift of the supernovae, which could be used to verify the anisotropy through the observation, has been derived.
