The gauge factor increase and the hypothetical emerging of the matter objects on the horizon in the standard model of universe

In the standard model of universe the increase in mass of our observed expansive and isotropic relativistic Universe is explained by the hypothetical assumption of matter objects emerging on the horizon (of the most remote visibility). However, the mathematical-physical analysis of the increase of Universe gauge factor shows that this hypothetical assumption is non-compatible with the variants of the standard model of universe by which - according to the standard model of universe - can be described the expansive evolution of the Universe.
