If our universe is ultimately destined to perish, can we move to another? This question, which has occupied the minds of cosmologists all over the world in recent decades, is at the center of the book "Parallel Worlds" by the famous physicist and brilliant popularizer of science Michio Kaku. Another universe, he writes, may be a millimeter away from us, but it is inaccessible because it exists in hyperspace, beyond our four dimensions. How to conquer this hyperspace, is it conceivable? Kaku sees such an opportunity in the new theory of the Multiverse - a world formed by many universes, including ours - one of the great many. But in order to understand the future of cosmology, it is necessary to understand its past vicissitudes and the most important modern discoveries. And the reader is invited to this exciting journey right now.
