About this item
Are there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered such questions, but there was a time when scientists dismissed these notions as outlandish speculations. Not any more. Today, they are the focus of the most intense scientific activity in recent memory. In Hyperspace, Michio Kaku offers the first book-length tour of the most exciting (and perhaps most bizarre) work in modern physics.
The theory of hyperspace (or higher dimensional space)—and its newest wrinkle, superstring theory—stand at the center of this revolution, with adherents in every major research laboratory in the world. Beginning where Hawking's Brief History of Time left off, Kaku paints a vivid portrayal of the breakthroughs now rocking the physics establishment. Why all the excitement? As the author points out, for over half a century, scientists have puzzled over why the basic forces of the cosmos—gravity, electromagnetism, and the strong and weak nuclear forces—require markedly different mathematical descriptions. But if we see these forces as vibrations in a higher dimensional space, their field equations suddenly fit together like pieces in a jigsaw puzzle, perfectly snug, in an elegant, astonishingly simple form. This may thus be our leading candidate for the Theory of Everything.

Kaku, a renowned theoretical physicist, has a gift for taking the seemingly incomprehensible realms of quantum physics, higher dimensions, and string theory and making them not only understandable but also captivating. His enthusiasm for the subject is infectious, turning what could be a daunting read into an adventure that's as thrilling as any science fiction novel.
The book delves into topics that challenge our traditional notions of reality, such as parallel universes and time warps, with a clarity and insight that only someone of Kaku's expertise can provide. He guides the reader through these complex ideas with the ease of a seasoned teacher, using analogies and imagery that bring abstract concepts to life.
"Hyperspace" is also a testament to Kaku's ability to foresee the future of science. He discusses how these advanced theories could potentially transform our understanding of the universe and lead to groundbreaking technological advancements. It's a glimpse into the potential future of human knowledge and capability, presented with a balance of scientific rigor and speculative wonder.
Perhaps one of the most compelling aspects of the book is how Kaku connects these high-level scientific theories to the fundamental questions of our existence. He explores not just the how, but the why, inviting readers to ponder our place in the universe and the nature of reality itself.
TL;DR: Michio Kaku's "Hyperspace" is a brilliant, captivating exploration of some of the most advanced and exhilarating concepts in modern physics. With his clear, engaging style, Kaku turns complex theories into an enthralling narrative that opens up the universe in ways that are both enlightening and deeply thought-provoking. It's a must-read for anyone fascinated by the possibilities of science and the mysteries of our cosmos.
The book takes us on a journey through the discovery-history of higher dimensions and the quest to unify the laws of physics. It introduces us to Riemannian geometry and explains how forces can be viewed as consequences of geometry in higher dimensions (Hyperspace) a concept that was later used in the General Theory of Relativity, Kaluza-Klein theory as well superstring theory. The laws of physics become more unified, simpler and more beautiful if you add a few dimensions. He convincingly makes the case that you can discover the secrets of the Universe by peering into Hyperspace. The book also discusses topics such as the history of modern physics, relativity, quantum physics, the standard model, GUTs, super gravity, black holes, the big bang, parallel universes, etc. Towards the end of the book he is discussing the fate of the Universe and the fate of human civilization, and the threats we face from the potential of nuclear war, global warming, and possible collisions with asteroids.
The book does not go into depth on any of the multiple topics discussed. It is not that kind of a book. However, on some minor topics I found it to be misleading, particularly on the topics of parallel universes and “Schrödinger’s cat”. For example, he states on page 261 “To Schrödinger, the idea of thinking about cats that are neither dead nor alive was the height of absurdity, yet nevertheless the experimental confirmation of quantum mechanics forces us to this conclusion.” The last part is simply incorrect. This is an interpretation issue, not an experimental issue, and it is sorted out in different ways by more modern interpretations of quantum physics such as the ensemble interpretation and the relational interpretation of quantum physics, or via "decoherence". As for me, when I as a young student taking classes in Quantum Physics at the end of the 1980’s I adopted what was essentially a pre-cursor to the relational interpretation because of what I noticed when I tried to perform Galileo transforms on quantum wave functions. There’s no real contradiction and there are no multiple worlds (universes) needed to explain this. I’ve seen other popularizers confuse people the same way, and I think it just turns people off.
Anyway, other than the above minor complaint, I think this was a very enjoyable and interesting book that I am very glad that I’ve read.
