An intriguing book to say the very least. This book walks you through many of the sciences; mostly theoretical in nature. You do not have to be a science geek to read it, but trust me it would be helpful in understanding a greater portion of the book. Regardless of that fact, it was at the very least a rollercoaster ride learning a bit about many differing theories about hyperspace, wormholes, black holes, time travel, parallel universes, and other dimensions. In some parts it was an easy read, and other parts were a tough read. Overall, I found it to be a great book that touched on many theories and subjects of science which I have always been interested in, but just never read about or studied. I left this book with several questions and thoughts, such as: As civilizations mature they tend to disappear; as these civilizations rise to power and harness the power of the atom, are they destined to destroy themselves? Is the galaxy destined to continue to expand, or will it eventually – at some point in time – begin to contract?
I have seen Michio Kaku on several programs on the news channels, Discovery and Science channels. He is a very interesting individual who seems to be able to put very tough subjects into very simplistic terms.
