The Singularities in Quantum Cosmology
Abstract
A cosmological model is proposed, in which quantum effects lead to infinitely many terms nonlinear in curvature, and these terms lead to the following conclusion: the physical singularity (i.e., a state with infinite matter densityp) occurs int≃10^{43} s, when the curvature is finite. An attempt is made to give physical interpretation of this model from the viewpoint of the ‘foamlike’ model of spacetime.
