Specialist on a quantum gravitation, theories of space strings, director of Institute of cosmology of University Тафтса (THE USA) Alexander Виленкин tells in the best traditions of popular literature, how the most difficult constructions were born and formed, describing a structure and questioner scenarios evolutions of our Universe, acquaints with the main acting persons of theoretical physics of XX and XXI of centuries. This book, however, relates not only to the cosmology, but also to cosmological philosophy. The creative going near physical constants brings an author over to the idea, that our Universe - one of great number of the worlds existing in parallel with each other. This idea - idea of multiuniverse - it can not neither prove nor refute through supervisions, but her originality and elegance did her identically attractive both for many prominent physicists and in the same measure for writers-fantasies.
