Towards the theory of the evolution of the Universe

A self-consistent account of the most simple nongauge vector fields leads to a broad spectrum of regular scenarios of the temporal evolution of the Universe completely within the frames of Einstein's general relativity. The longitudinal nongauge vector field is "the missing link in the chain," displaying the repulsive elasticity and allowing the macroscopic description of the main features of the Universe's evolution. The singular big bang turns into a regular inflation-like state of maximum compression with the further accelerated expansion at late times. The parametric freedom of the theory allows us to forget the troubles of fine-tuning. In the most interesting cases the analytical solutions of Einstein's equations are found.
