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 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 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.

  1. Causal Horizons, Geodesic Completeness and Stability in Slow Contraction Cosmology

    gr-qc 2026-07 conditional novelty 5.0 of 10

    Semi-infinite slow contraction (ε>3) is past-complete and horizon-free, asymptotes to Minkowski, evades BGV, and stays stable, unlike contracting de Sitter.
