People have always tried to explain the causes of various phenomena in the surrounding space, as well as the cause of the emergence of the word itself, which is called the Universe in our time. At the present stage of development of consciousness, a picture of the world emerged from the primary singularity(a special state of matter). According to the concept generally accepted in cosmology, the Universe arose as a result of the Big Bang and is still expanding. This point of view was confirmed in the first half of the last century.
The theory of a non-stationary universe, proposed by the soviet mathematician Friedman and observational data obtained by Hubble, found that distant galaxies scatter at speeds proportional to the distance from the observer, where the proportionality coefficient is the Hubble constant. Einstein argued from the start that the universe must be stationary. Friedman, who entered into a dispute with him, on the basis of field equations (Einstein’s equations) constructed a whole class of homogeneous isotropic models, among which expanding, contracting, and…
