Smooth Initial Conditions from Weak Gravity

High Energy Physics - Theory 2011-02-16 v2 General Relativity and Quantum Cosmology

Abstract

CMB measurements reveal an unnaturally smooth early universe. We propose a mechanism to make this smoothness natural by weakening the strength of gravity at early times, and therefore altering which initial conditions have low entropy.
