The Arrow of Time and the Initial Conditions of the Universe

Robert M. Wald

Abstract

The existence of a thermodynamic arrow of time in the present universe implies that the initial state of the observable portion of our universe at (or near) the ``big bang'' must have been very ``special''. We argue that it is not plausible that these special initial conditions have a dynamical origin.
