Abstract

The universe we observe is homogeneous on super-horizon scales, leading to the "cosmic homogeneity problem". Inflation alleviates this problem but cannot solve it within the realm of conservative extrapolations of classical physics. A probabilistic solution of the problem is possible but is subject to interpretational difficulties. A genuine deterministic solution of the homogeneity problem requires radical departures from known physics.
