  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.
