Evolution of the open cosmological model with radiation

It is researched earlier discovered open cosmological model received by means of a method of the equivalent potentials. It is as a result shown, that evolution and age of the Universe strongly depend on the relation of the parametres entering into model and defining both presence of radiation, and presence of a mass substance. Besides, the Universe warming-up at an initial stage also depends on these parametres. The illustrative diagrammes confirming above told are given. However examination has shown also inconsistence of introduction above the specified parametres as the constant parameters for all time of evolution of the Universe. Roles of these parametres from the Universe origin till the present epoch change on to the opposite.
