Abstract

In daily life the world shows a marked distinction between past and future, but (with a minor exception) the laws of physics are symmetric in time. Gerald Whitrow was among the first to realize that the resolution of this paradox lay with cosmology and the initial conditions at the birth of the universe. But this simple conclusion conceals some deep subtleties that took a new twist with the emergence of quantum cosmology and the inflationary universe scenario. The issue has still not been fully resolved, and remains one of the great outstanding scientific mysteries.
