Entropy, black holes, and the new cyclic universe

Blog Article

We track the evolution of entropy and black holes in a cyclic universe that undergoes repeated intervals of expansion followed by slow contraction and a smooth (non-singular) bounce.In this kind nyx 22 brush of cyclic scenario, there is no big crunch and no chaotic mixmaster behavior.We explain why the entropy following each bounce is naturally partitioned into click here near-maximal entropy in the matter-radiation sector and near-minimal in the gravitational sector, satisfying the Weyl curvature conditions conjectured to be essential for a cosmology consistent with observations.As a result, this kind of cyclic universe can undergo an unbounded number of cycles in the past and/or the future.
