The book describes a new approach to Einstein's theory. The possibility of moving in space at speeds exceeding the speed of light is shown. The principle of the transition of matter through the light barrier and the presence of a zone of uncertainty in its vicinity are explained. The principles of exchange of matter and energy with hyperspace are shown. Accurate calculations of the cosmological redshift and the temperature of the background radiation of the Universe are given, as properties of the Dirac Sea, and, as a consequence, the stationarity of the Universe. The parameters and properties of white holes as the basis for the structure of galaxies and other cosmic objects are given. And much more.
