Abstract: A semiclassical mechanism which suppresses the weak anisotropies of aninhomogeneous cosmological model is developed. In particular, a wave functionof this Universe having a meaningful probabilistic interpretation is obtainedthat is in agreement with the Copenhagen School. It describes the evolution ofthe anisotropies with respect to the isotropic scale factor which is regardedas a semiclassical variable playing an observer-like role. Near thecosmological singularity the solution spreads over all values of theanisotropies while, when the Universe expands sufficiently, the closedFriedmann-Robertson-Walker model appears to be the favorite state.
