Abstract:

I will discuss recent results from full-blown numerical relativity simulations of early-universe scenarios, demonstrating that slow contraction is a “supersmoothing” cosmological phase that homogenizes, isotropizes and flattens the universe and can do so far more robustly and rapidly than had been realized in earlier studies.
