Based on the model of the Universe with initial minimum entropy, the article considers the evolution of the Universe as brane of four-dimensional space. Taking into account that the radius of the fourdimensional sphere increases with the speed of light, it is shown that the possibility of observing galaxies is limited to a four-dimensional space-time cone with a forming angle of 1 radian, which is about 5% of all galaxies. The dependence of the mass and position of galaxies in space-time since the moment of radiation has been found. This dependence explains the reason for the reduced mass of matter in the Universe, found from astronomical studies. It is shown that in astronomical studies can be found no more than 8% of the real density of matter. It was also shown that gravity takes main role in the redshift of the emission spectra of galaxies localized in clusters at a distance of more than 4 billion light years. This fact explains the presence of a cluster of quasars in the absence of quasars in other large parts of the sky. In this case, the distance to quasars may turn out to be significantly less than that given in the scientific literature.
