We can assume the hypothesis that the Universe has a closed life cycle of development. The expansion process and the compression process. Logically, Nature should have closed cycles - the processes of expansion and contraction.    The Neutron Universe hypothesis is based on the definitions and properties of the mass interaction potentials of the Universe. It is assumed that the original matter of the Universe was a neutron nucleus with a size of  6.2 astronomical units and the number of neutrons . This core, in the course of its development, broke up into millions of clusters of galaxies like the Virgo cluster of galaxies. The individual galaxies in this cluster are similar to our own galaxy, the Milky Way. All astronomical objects in our Galaxy are showing signs of the formation of the neutron excess of dense objects.
