Abstract
A model of the early universe at times close to the Big Bang is proposed where the Friedman-Robertson-Walker model does not work. It is based on an asymptotic study of the Einstein-Maxwell equations at short distances. It is shown that under certain conditions their solutions acquire spherical symmetry. A criterion for isotropization of solutions of the Einstein-Maxwell equations is formulated. Solutions of the Maxwell-Einstein equations allow to find a space-time metric. At short distances, the metric has a singular Schwarzschild form, where the mass of matter in the entire universe plays the role of mass. On the periphery, the metric is determined from Maxwell's equations in a curved space-time. It is shown that the singularity is shielded by this peripheral solution. The results obtained make it possible to clarify the details of phenomena in the field of modern cosmology, as well as the theory of electromagnetism and gravity.
