interaction, forming a new hidden vacuum and visible (baryonic) matter. The energy density throughout the Universe decreases, new regions appear, covered by the gravitational transition from a hypothetical Background Gravitation Field. When a certain minimum (critical energy density) is reached, the gravitational transition into a new hidden vacuum and visible matter will begin to decrease its acceleration. We recreated the inflationary phase of the Universe on the basis of the density decrease postulate. An experiment was also carried out to compare the angular diameters of the distances between pairs of quasars based on data from open access.
