Wormhole cosmology and the horizon problem

Abstract

We construct an explicit class of dynamic Lorentzian wormholes connecting Friedman-Robertson-Walker spactimes. These wormholes can allow two-way transmission of signals between spatially separated regions of spacetime and could permit such regions to come into thermal contact. The cosmology of a network of early Universe wormholes is discussed.
