Abstract

It is well known that the spontaneous breaking of discrete symmetries may lead to a conflict with big-bang cosmology. This is due to the formation of domain walls which give an unacceptable contribution to the energy density of the Universe. On the other hand it is expected that gravity breaks global symmetries explicitly. In this work we propose that this could provide a natural solution to the domain-wall problem.
