The book serves well as an introduction to the multiverse and will open up many people´s eyes (John Gribbin). Every chapter opens level after level of previously unimaginable, mind-expanding realities (Oliver Sacks ) Product Description There was a time when ´universe´ meant all there is. Everything. Yet, as Brian Greene´s extraordinary book shows, ours may be just one universe among many, like endless reflections in a mirror.
