Scientific paper

We consider the character of the solutions for a homogeneous anisotropic cosmological model of Bianchi type I, with allowance for the second viscosity. It is shown that the viscosity is unable to eliminate the cosmological singularity, in contrast to the previously investigated Friedmann case. The model considered in the present paper has the remarkable property that near the cosmological singularity the gravitational field produces matter within the framework of the classical (rather than quantum) theory.
