Parallel Worlds: A Journey Through Creation, Higher Dimensions, and the Future of the Cosmos Paperback – Illustrated, February 14, 2006

As those into the hard sciences know we have come a long way in the study of modern day physics and cosmology. What used to be considered science fiction and pseudoscience has become acceptable and valid scientific theories and hypothesis. The last six months I have been reading numerous books on physic, cosmology, time travel and related topics. I just finished this fascinating 436 page soft book (Parallel Worlds: The science of alternative universes and our future in the cosmos by Michio Kaku) and found it to be a delightful read.I had read sever previous books by this author so I was familiar with his work. This book explains in great detail the most recent developments in physics and cosmological theories. This easy to read book is organized into three parts:The first part (The Universe) covers baby pictures of the universe, the paradoxical universe, the big bang, and inflation and parallel universes. The second part (The multiverse) explores dimensional portals and time travel, parallel Quantum Universes, M-Theory, a designer universe, and searching for echoes from the eleventh dimension. The final part (Escape into hyperspace) focuses on the end of everything, escaping the universe and beyond the multiverse.If cosmology, physics and other universes fascinates you this is a book you should check out.Rating: 5 Stars. Joseph J. Truncale (Author: Tactical Principles of the most effective Combative Systems).

In this book, Michio Kaku, a leading theoretical physicist, discusses the current state of the search for a unified theory to explain everything, from quantum physics to relativity and everything in between. In layman's terms, he discusses the history of string theory and M-Theory, the current form of string theory, and what it all means in terms of the possibilities of alternate universes, time travel, and the origin of the universe. Kaku discusses the possibilities of more than 3 spacial dimensions, as implied by the theory. Kaku goes on to discuss the ultimate fate of the universe: a continual expansion resulting in temperatures too cold to support life, or a crushing implosion resulting in temperatures too hot to support life. Kaku discusses the possibility that M-Theory may increase our understanding of the universe (or multiverse) enough to be able to travel into a different universe, or back in time, before our universe collapses. Kaku ends with a philosophical discussion on our place in the universe and what the point of it all is.If you have read Kaku's book "Hyperspace", some of this book will be review, as he includes some of the same concepts of extra dimensions in this book.Kaku explains the science in such a way that the layperson can understand it fairly well. He doesn't go into much mathematical detail; he only explains enough so that the reader understands what the theory means and doesn't get bogged down with all the details. This is what makes Kaku's writing great. His books, such as this one, are written for those who haven't studied physics in depth but who are interested in what is going on in the field of physics and the search to understand the universe.The bottom line: Kaku is a great resource for the latest developments in theoretical physics and our understanding of the universe.

I must say I have read many of Kaku's books and from my perspective they are very well written and in a style and prose that entertain and stimulate. His love for science is infectious and it leaves one with a feeling of awe and wonder for the Universe. A Universe that too many people take for granted.However, I must answer a rather poor review of this book by "Panabear" who stated the following:"I'm surprised to see such high ratings for this book, as I don't know anyone scientifically inclined that found this to be a good book".And who might that be panabear? , you and your brother?How pathetic and how wrong. Here is list of truly scientifically inclined individuals and organizations that do praise the book.They include:Brian Greene, Professor of Theoretical Particle Physics, Columbia University, writer of the: The Elegant UniversePaul Davies, Australian Centre for Astrobiology, Macquarie University , THE WINNER OF MULITPLE AWARDS FOR HIS SCIENTIFIC WRITINGSAnd finally one of most prodigious Scientific journals in America: The Scientific American. Which ALSO heaped praise on the book.It seems that panabear is a one star reviewer. Maybe panabear should stay at the zoo.
