Supersmoothing through slow contraction

Glushchenko (Department of Physics, Princeton University, Princeton, USA) ; Anna Ijjas (Max Planck Institute for Gravitational Physics (Albert Einstein Institute), Hannover, Germany; Gottfried Wilhelm Leibniz Universität, Hannover, Germany) ; Frans Pretorius (Department of Physics, Princeton University, Princeton, USA) ; Paul J. Steinhardt (Department of Physics, Princeton University, Princeton, USA)

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.
