Performing a fully non-perturbative analysis using the tools of numerical general relativity, we demonstrate that a period of slow contraction is a `supersmoothing' cosmological phase that homogenizes, isotropizes and flattens the universe both classically and quantum mechanically and can do so far more robustly and rapidly than had been realized in earlier studies.

  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.
