Measurements of the cosmic microwave background ( cmb) radiation provide the strongest evidence for the isotropy of the observable universe on the largest scales. However, the cmb is received from regions which were not in causal contact at the time of last scattering. This is the horizon problem and the generally accepted solution is to invoke an inflationary period in the early universe. We consider the possibility that the universe did not necessarily inflate, but was filled with a network of evolving wormholes connecting otherwise causally disjoint regions. These wormholes emerged naturally from the Planck epoch and need only have stayed open for a very brief time (δt<10-34 sec) in order to have thermalized the early universe.
