Gas of wormholes as a model for dark energy

E.P. Savelova1

Abstract

We assume that some amount of dark energy appears due to vacuum polarization in external classical fields. In the early Universe, perturbations in this energy may form actual wormholes. We show that actual wormholes give a negligible contribution to the change in the vacuum energy density, while their contribution to the mean curvature is apt to form the observed dark energy phenomenon. Using the contribution of wormholes to dark matter and dark energy, we find estimates for the characteristic parameters of the gas of wormholes.
