Physics

Scientific paper

It is shown that for a definite value of the spin-spin interaction constant, which must be introduced from gauge considerations, the Einstein-Cartan equations without the Λ term admit a cosmological solution in the form of a steady-state de Sitter metric. It is asserted that such a solution can serve as a model of the pre-Friedmann stage of the expansion of the universe, when the spin-torsion interaction is comparable with the energy-momentum-curvature interaction. The value of the interaction constant is obtained (θ˜-10-20) under the condition that the de Sitter stage was realized at quantum densities (1094 g/cm3).
