The only non-contradictory model of universe
  The Friedmann equations of universe dynamics describe the infinite number of the Friedmannian models of universe. The consistent and distinguished relativistic, classical-mechanical, quantum-mechanical and formal-logical analysis of the Friedmannian universe models leads to a surprising and unexpected conclusion: The Friedmannian model of the flat expansive homogeneous and isotropic universe with the zero gravitational force state equation is the only model of universe, which does not contradict the: 1st Einstein general theory of relativity (and its special partial solutions: the Einstein special theory of relativity and the Newton theory of gravitation); 2nd quantum mechanics; 3rd fundamental formal principles of logical thinking; and 4th observations.
