Problems of the matter increase in our observed expansive and isotropic   relativistic Universe
  The increase in mass of our observed expansive and isotropic relativistic Universe in the present relativistic cosmology is explained by the extensive assumption of the matter objects emerging on the horizon (of the most remote visibility). However, the physical analysis unambiguously shows that this assumption contradicts the theory of relativity, quantum mechanics, classical mechanics and observations.
