Title: GENERATING A HOT BIG BANG VIA A CHANGE IN TOPOLOGY
Abstract: This letter uses ideas developed recently in semiclassical quantum gravity to argue that many qualitative features of the Hot Big Bang generally assumed in cosmology may be explained by the hypothesis that, interpreted semiclassically, the Universe “tunnelled into being” via a quantum fluctuation from a small (Planck-sized), topologically complex entity to a topolo-gically trivial entity (like a Friedmann Universe) that rapidly grew to a more macroscopic size.
