Cosmological principle – The fundamental principle of all modern cosmological models is the cosmological principle. It consists in the fact that the characteristics of the Universe are the same from the points of view of observers who are at all its points at the same time. This explains the lack of clear directions in the Universe and the fact that matter in space is distributed relatively uniformly. It is generally accepted that all observations have confirmed the isotropy and homogeneity of the Universe.
