Eternally existing self-reproducing inflationary universe.
Abstract
It is shown that the large-scale quantum fluctuations of the scalar field φ generated in the chaotic inflation scenario lead to an infinite process of self-reproduction of inflationary mini-universes. A model of an eternally existing chaotic inflationary universe is suggested. It is pointed out that whereas the universe locally is very homogeneous as a result of inflation, which occurs at the classical level, the global structure of the universe is determined by quantum effects and is highly non-trivial. The universe consists of an exponentially large number of different mini-universes, inside which all possible (metastable) vacuum states and all possible types of compactification are realized.
