Scientific paper

The notion of a spontaneously broken gauge symmetry provides the basis for popular unified theories of weak and electromagnetic interactions. It is proposed that the spontaneous breakdown of gauge symmetries may have a cosmological origin. The occurrence of a phase transition at some early stage of development of an expanding universe is considered and a 'proto-type gauge theory' of the Salam-Ward-Weinberg variety in a curved space with prescribed metric tensor is discussed.
