The Friedmann equations of universe dynamics describe infinite number of relativistic universe models in Newtonian approximation, but only in one of them the Newtonian non-modified relations are valid. From these facts it results that the Universe is described just by this only Friedmannian universe model with Newtonian non-modified relations.3 pagesGeneral Relativity and Quantum Cosmologytext
