ON THE TIME PROBLEM IN QUANTUM COSMOLOGY

Abstract

The problem of time in quantum cosmology in the framework of quantum geometrodynamics is considered. The birth of the Universe is interpreted as the tunneling of a planchet through a potential barrier. Under the barrier, time is imaginary. In the classical region there is a real time determined by the phase of the quasiclassical wave function, the dependence of which on the scale factor describes the evolution of the Universe.
