THE DARK ENERGY EXPLAINED BY A SCHWARZSCHILDIAN COSMOLOGY - <em>ET CETERA</em>

Abstract

In a First Part we give a Schwarzschildian generalization of the Newtonian, and Friedmannian, models of universe. By virtue of the Hilbertian gravitational repulsion, our formulation explains the red-shifts of the galaxies and the existence of a DARK ENERGY. In the Second Part we discuss two ignored consequences of Friedmann’s metrics: i) the existence of a time coordinate such that there is no expansion of Friedmann’s universes; ii) a corollary of a theorem by Hönl (1949), which tells us that the physical meaning of the point-origin of the galaxy paths is very problematic.
