The black hole phase of the Universe
A state of the universe by its average density and possible radius is considered. By a mass assessed on the basis of these parameters, the expectable cases when the universe may occur inside the Schwarzschild’s sphere and form the black hole, are calculated. An inner non-stationary nature of the Universe by an example of the evolutionary stages of its existence as the black hole are analyzed, which indicates that a non-stationary nature of the black holes is their usual form of state. © 2011 Bull.
