Hyperspace: A Scientific Odyssey Through Parallel Universes, Time Warps, and the Tenth Dimension
Are there other dimensions beyond those of our everyday experience? Are there gateways to parallel universes? What happened before the first day of Creation? These types of questions are at the center of current scientific activity. Indeed, many physicists today believe that there are other dimensions beyond the four of our space-time, and that a unified vision of the various forces of nature can be achieved, if we consider that everything we see around us, from the trees to the stars are nothing but vibrations in hyperspace. Hyperspace theory - and its more recent derivation, superstring theory - is the eye of this revolution. In this book, Michio Kaku shows us a fascinating panorama, which completely changes our view of the cosmos, and takes us on a dazzling journey through new dimensions: wormholes connecting parallel universes, time machines, "baby universes" and more. Similar wonders are emerging in some pages in which everything is explained with elegant simplicity and where the mathematical formulation is replaced by imaginative illustrations that allow the problems to be visualized. The result is a very entertaining and surprising book, which even leaves behind the greatest fantasies of the old science fiction authors.

Michio Kaku apparently spent his childhood building super-colliders in his parents' garage. It paid off. He's clearly brilliant, and best of all, he's not lost his imagination. One sad fact of modern physicists is that precious few of them have any imagination, and are incapable of thought experiments and relative flights of fantasy. As Kaku has pointed out, fantasy fueled more great discoveries in science than pure science ever did on its own. In this book he uses what we know about quantum physics to explore possibilities formerly relegated exclusively to science fiction. In doing so, he should be admired. He is merely asking us to consider what some great minds in both literature and physics have imagined, and in doing so, manages to make what we do know seem almost simple by showing us how much we truly don't know. He's amazingly talented, imaginative, and best of all, he knows his math. He also knows how to use that math to dream of what's possible. An absolutely fun book to read.

This is the book that allowed me to fool an entire room of graduate students into thinking I was utterly Brilliant. It is a really good crash course on just what the hell Quantum, String, Unified Field Theory ad Superstring actually are. Lays down the history and concepts in a way that makes sense and makes you get it.
Particularly savvy readers will start making the other logical leaps. If we are thinking energy vibrating along a 10-dimensional string, what does that say about the frequency of sentience in the universe? Since energy can't go anywhere and sentience is a factor of energy, what the hell really does happen to us when we die?
Enjoy your trip down the rabbit hole.

I think this book is superb.
String theory is complicated and it would be easy to make the subject dense and unappealing.
However. Michio Kaku has a lightness of touch that enables the reader to think they might understand what's going in in our world where the extra dimensions are rolled up to the size of the Planck length.
The author also includes references to the great scientists of yesterday, the Newtons, Faradays, Maxwells as well as the scientists of the 20th Century allowing the reader to see how theories have changed through the centuries.
There's an intriguing section on Type I, II, and III civilisations.
The Earth is a Type 0 civilisation at the moment.
A Type I civilisation is one that controls the energy resources of an entire planet, controls the weather on its home planet, and has explored its own solar system.
A Type II civilisation is one that controls the power of the sun and has begun the colonisation of local star systems.
A Type III civilisation is one that controls the power of an entire galaxy and can probably manipulate space-time.
It's almost certain that any visitors from outer space to Earth would be from a Type III civilisation, in which case why would they bother with us? We'd have nothing to impress them and anything they could pass on to us would be beyond us, almost like a human communicating with an ant colony and trying to teach them how to build a solar panel.

DNF at chapter 10. It was a bit too dry and technical for me. While the chapter names were intriguing and there were interesting anecdotes in each chapter, it was still slightly too boring, even with the pictures, for me to read into and understand the developments of modern physics. There wasn't much holding it together, i.e. the book only follows the overthrow of each theory as its organizing structure. It also seemed to ramble on with analogies that weren't that great to follow, eg the wood vs marble and flatland comparisons. Though I'm sure that Michio Kaku is quite knowledgable about the theories mentioned in the book (as evidenced by his other books) I expected this book to be more in story form like Flatterland and thus easier to read. Overall, this book was just disappointing for me. I expected it to be a fun and informative telling of the evolution of dimensional theories but ended up getting a book that was difficult to read and closer to a paper than novel.

5 stars for his lessons on physics, science, and mathematics. No stars for his musings on religion, god, and evolution.

This author writes my favourite non fiction science books and this one did not disappoint. Technically it is the re-release of a previously published book with a new audio version but I am happy that this format will bring this book to a larger audience.
This book is largely framed around hyperspace or dimensions beyond the four we can already perceive. This topic alone was fascinating but I appreciated that the author expanded into adjacent topics from multiworld theories to discussions of an intelligent creator.
Disclaimer I received a copy of the audiobook from the publisher.

It was OK just because the science fiction at the end was a lot of fun.
Dr. Kaku alternates through two styles -- talking to the reader like they're completely stupid and then talking to them like they've taken a college physics class. I'm neither, I understood what he was writing, and was just insulted. The cornerstone of Hyperspace theory is that there were 10 dimensions for a fraction of a fraction of time in the first fraction of time of existence for this universe, but 6 of them probably don't exist since. Um, so there aren't 10 dimensions -- there might have been. And then the whole premise is that I should accept the premises in the book even though he acknowledges there may never be proof?
And the difference between this and religion is....oh, I see, there is none. Fifth dimensional beings could exist, but not God? Interesting assertion. So long as we're just accepting things on faith, let me toss this one out there: God is a 5th dimensional being.
But of course, it's sexy to act like you're smart -- and when someone like Dr. Kaku publishes a sexy bit of science fiction and calls it researched science, everyone's afraid to look like they don't "get it." It's like living in a Rand novel.
It's OK to call bullsh*t on someone in the sciences, people. And in this instance, I do.

Me lo he pasado muy bien, llevaba mucho tiempo lejos de la divulgación y es que a veces los traumitas nos apartan de cosas que realmente nos gustan y disfrutamos. Libro entretenido y manejable, un recorrido por el último siglo de física donde nos enseñan lo micro y lo macro y lo difícil que es juntarlo todo. Planteamientos a futuro. Entendinble y con buenos ejemplos, didáctico.

If you've thought science is dull or perhaps too far beyond you, then please meet Michio Kaku. He writes about theoretical physics in a way that will fill you with wonder and possibility. He takes what would otherwise be very complex concepts and conveys them using metaphors that every average joe can understand. The number of a-ha moments I had reading this book were too many to count. What a terrific read.

I got this on my birthday from my mother. Thank you 💝💝💝💝
Wow! What a wild ride it was! From history to science, from scientists to ports, this book left no stones unturned. Although I wanted a book with more equations and mathematics ,and this book had ZERO equations, I loved it immensely. I didn't know topics like string theory,why 10 dimensions are needed etc and this book made them clear for me. Again, I knew topics like relativity and quantum mechanics, but didn't know the history behind them. This book was long, and took me a long time to finish it, but it was worth it.
Pros: easy language, fluid writing style, covered interesting and complexed concepts like hyperspace, quantum mechanics, relativity, particle physics and cosmology.
Cons: Can be felt boring from time to time because of the history part.

Started strong. An introduction to non-Euclidian geometry, string theory, and related concepts. Made me fantasize about learning the math.
Got more and more speculative toward the end, and not so interestingly so. Like many books, this one would have been improved by a ruthless editor. Still, worth a read if the topic interests you.

There was no need for it to take me so long to read this book, because it's not a difficult read and Kaku's writing style is easy to follow. In fact it took me eight years to read because I noticed that I bought it in 2015 and kept it in my drawer, but I read it at the right time I suppose. Published in 1994, it's dated now, which is why I want to read his more recent works because I'm sure that science has made dramatic advancements over the past 29 years. As the title suggests it is an odyssey through scientific theories of the nature of reality, the premise being to find a single theory that unites the four forces of nature. I found myself often thinking about the movie Interstellar and how scientifically accurate it is, and in general this pursuit to know the mind of God shows how great humanity can be, that we can be godlike ourselves. It's rather inspiring.
There's certain things in this book I'll come back to, but I generally don't put a tremendous amount of energy into remembering things that I don't really need to know at any particular point in my personal journey. I'm not a physicist after all, however my magical interests invariably lead me to be interested in physics. Lastly, I liked how philosophical it is, and Kaku gives some attention to philosophy in the conclusion and says how the giants of physics don't dismiss it. People say this and that about philosophy, but it's rather important to have sound conceptual foundations for everything in life. It's literally important to everything -- everything issues from philosophical underpinnings, and our progress as a race depends on our philosophical conceptions of aspects of reality, so I don't understand the disrespect to the discipline of philosophy commonly found in the scientific community. My opinion is that we need to work in harmony to make even quicker progress and stop the fragmentation of our disciplines. Philosophy and science should never really have been separated in the first place. Ok that's it for now, I didn't really put a lot of energy into this review. Just some quick notes. Maybe I'll soon make some changes and write a better review.

I am now officially a Michio Kaku fan. This book explains physics as it should be taught in school. His simplistic approach begs the reader for more information. I also love physics now because I understand it a lot more thanks to Mr. Kaku's books. The school systems should think about this book as part of their cirriculum to teach the importance of understanding physics. Highly recommended.

This is one of the popular science books that got me so interested in doing physics in the first place. Accessible to me before I even took a physics class, it should be accessible to most anyone with interest. Very interesting questions raised about space and time/parallel universes/etc. New ideas (as of date published: 1994) are discussed in a non-technical way. Also, very well written and easy to read (with humor and everything!).
August 19, 2015
Michio Kaku makes some amazingly complex and mind-bending concepts accessible to the lay reader (i.e., me, and maybe you, too, if you're also not a physicist). He sprinkles the book with entertaining and informative anecdotes and his passion for the topic is infectious. Still, I shudder to think that no author ever addresses Schrödinger's ailurophobia. Here's hoping the 6-dimensional universe opens up just as this one closes!

Un libro fantástico para descubrir una nueva perspectiva del universo.
Read
February 4, 2023I'll come back to this as soon as I extend my knowledge of Kaluza-Klein theory a mathematical basis (therefore I have not rate it yet). The book is substantive and mostly intelligible, although you need to evince more interest in higher dimensions and physics than an average i-like-watching-interstellar person to understand the string theory.

Hyper-generic pop-sci driven to its apex.
For all that it pretends to be a coherent exploration of higher dimensions in both senses of the word (mathematical and sci-fi), Hyperspace is a series disconnected vignettes more concerned with hitting every topic on his list of popular science tropes than telling a coherent story—everything you could expect to be in a work of popular physics is in here, regardless of how much sense it makes to include it. If you're looking forward to seeing another triangle drawn on a saddle or reading another synopsis of that Heinlein story about the girl who became her own parents, Kaku's your guy. (For a while he had me wondering if I'd already read this one and just forgot to review it, but no.)
The physics stuff is mostly⁰ covered in the exact same (shallow) way almost everyone else has covered it,¹ but he doesn't stick to that, because other writers don't. His inevitable discussion of things like the anthropic principle and the cosmological argument (you know: those things that were in all pop-sci from, say, the '80s all through The God Delusion, after which they mysteriously became less fashionable) seem calculated to miss the point in a way that's meant to annoy literally anyone with any opinion at all, but they're not even the most embarrassing sections of the book—that would be the ``futurology''² that takes up most of the last quarter of it (I hope you like reading about the Kardashev scale again!).
In fairness I should also point out that this book was published in 1994, so it does predate a few hundred (but by no means all) of the books that made popular physics such a tired and derivative cottage industry; I don't think that excuses this one.
Writers who have written this exact book in a more competent way include Brian Greene, Brian Cox, and Michio Kaku.
--------
⁰ His discussion of Schrödinger's cat is notably worse.
¹ Kaku did manage to do something Lee Smolin and Peter Woit never could: make me doubt that string theory is actually a meaningful thing and not just a mathematical artefact; a lot of the big insights in his own actual work that he brings up do seem to come down to realising something he came up with was just a way of rephrasing older laws.
² A ``futurologist'', of course, being a sci-fi nerd with delusions of grandeur.

Complete audiobook review
Hyperspace is not a new book. It was first published in 1994. So it’s well-known among some readers. And although the material is almost 30 years old, it’s still relevant today.
I love Michio Kaku’s work. I saw some of his science TV series and always liked how he explained complex scientific facts in a simple form. I also liked references to some books that use the same ideas that the author explains.
Narration by Tim Lounibos is very good and easy to follow. The audiobook format is perfect for readers who want to read the book but maybe until now didn’t dare to dive in. As always, with science books, I recommend listening to this audiobook slowly. Although, the audiobook is easy to follow, and the author explains everything simply.

Michio Kaku je mým oblíbeným teoretickým fyzikem. Při čtení jeho knih si říkám, že kdyby profesoři na univerzitách měli aspoň polovinu jeho nadání popisovat složitou kvantovou fyziku tak, jako to dělá on, určitě bychom měli více inženýrů a třeba bych mezi ně patřila i já.
Kaku ve své starší knize s názvem Hyperprostor poutavě a zajímavě nastiňuje taková témata, jakými jsou světy vně prostoru a času, teorie superstrun, desátý rozměr, ale i černé díry, cestování časem a další osud vesmíru. Neříkám, že je to čtení vždy jednoduché, ale když máte alespoň základní znalosti matematiky a fyziky, jeho vyprávění vám pomůže věci uvést do souvislostí, zasadit je do kontextu a následně porozumět i složitějším konstrukcím. Za mě jednoznačně kniha, která má v mé knihovně svoje nezastupitelné místo.

Intriguing topics and Dr. Kaku is one of the few people who writes for the science enthusiast. Lot of information here. However, it was not conveyed in terms understandable for the general reader. Multitude of topics discussed without ever being broken down as to why I should care or what that means in terms I can relate to. Good book for someone well versed in mathematics or physics. I enjoy the topics discussed, but they need to be broken down in a way in which anyone could understand and relate to.

Michio Kaku did a terrific job of explaining to the layman scientific possibilities often depicted in sci-fi.
Read
December 3, 2019This is the first "hardcore" science book I've ever read, after wetting my appetite on The Universe In Your Hands and Astrophysics For People In a Hurry, and needing to dive deeper into these topics.
This book did not disappoint! It's a bit dated, as it was written in the 1990s, but I wanted to start with some of Kaku's earliest works to get a solid foundation of the concepts in here, before moving to his more recent books.
Hyperspace has left my mind buzzing with possibilities, with the wonder of the universe, as it took me through concepts like quantum physics, string theory, and higher dimensions.
This has been rewarding as a theoretical physics fan, and inspiring as a science fiction writer.
I'm excited to read Kaku's next book. It's already sitting on my shelf! 😌
This was my first hardcore science book, but it definitely won't be the last. :)))

Hyperspace: The Next Frontier
This was a really interesting and enlightening read.
I found it was on par with other Kaku books - I think I have read about 3 others.
He has a really particular way of writing that just gets right to the point, and I find it really well crafted.
Would highly recommend this book to anyone who enjoys physics, space, and philosophy.
3.8/5

“According to string theory, if we could somehow magnify a point particle, we would actually see a small vibrating string. In fact, according to this theory, matter is nothing but the harmonies created by this vibrating string. Since there are an infinite number of harmonies that can be composed for the violin, there are an infinite number of forms of matter that can be constructed out of vibrating strings. This explains the richness of the particles in nature. Likewise, the laws of physics can be compared to the laws of harmony allowed on the string. The universe itself, composed of countless vibrating strings, would then be comparable to a symphony.”

Remek könyv volt. Olvasmányos, több helyen humoros. Ha a fizika alapjai megvannak - általános + gimi - teljesen érthető lesz. A megértést, a vizualizációt több ábra és grafikon is segíti. Nagyon egyben lévő könyv ez, csak ajánlani tudom. Magyarul, az Akkor Kiadó gondozásában jelent meg 2006-ban.

This book has been on my shelf for years. I've looked at it and wanted to read it for years. I have always been too intimidated to pick it up. I have always been fascinated by physics , but mathematics always keeps me from jumping in. I barely survived Algebra in college.
If you are reading this and also feel this way, fear not! Kaku does a phenomenal job with this book and keeping the mathematics to a minimum and focusing more on the physical principles. You will get lost at times, concepts will go over your head, but he will bring you back. It is important to note that most of this stuff is over a physicists head as well. So, give it a read. I never once felt so overwhelmed I wanted to stop. I blew through this book much faster than I imagined. Why did I wait so long!?
If you are reading this and also feel this way, fear not! Kaku does a phenomenal job with this book and keeping the mathematics to a minimum and focusing more on the physical principles. You will get lost at times, concepts will go over your head, but he will bring you back. It is important to note that most of this stuff is over a physicists head as well. So, give it a read. I never once felt so overwhelmed I wanted to stop. I blew through this book much faster than I imagined. Why did I wait so long!?

Book for the science enthusiast who have an issue with mathematical equations, thoroughly entertaining, awakening, unputdownable.

It's up there, though not as accessible, as Hawking's "A Brief History of Time" and "The Universe in a Nutshell". Dr. Kaku does spend a considerable time walking the reader through how the theories of space-time and hyperspace arose and some of the historical and more mathematical stuff can be a little dense. However, the book opens really nicely with very vivid and amazing explanations of just how freaky hyperspace can be as well as the implications for the world of physics. The book also ends really well with how hyperspace can tell us something about how the universe will end as well as how it may help us, if we're still around, at that time as well as how to build a time machine and the potential evolution of an intelligent species into one capable of manipulating time and space.
I imagine his other book "Physics of The Impossible" which focuses more on trying to explain with physics for well-known sci-fi concepts would be as good as the beginning and end of this book. However, if you find that kind of topic, theoretical physics, black holes, time travel, 10 dimensional space, then I would recommend this book.

Ayer no pude parar de leer hasta terminar. Este libro es realmente bueno. Kaku tiene una didáctica bastante agradable y el libro está plagado de explicaciones meditadas para ser lo más sencillas posibles (a pesar de la complejidad de los temas tratados). Es un excelente libro de referencia y descubres datos curiosos que jamás te habrías imaginado.
El único contra es que ahora se encuentra desactualizado porque es pre-higgs y pre-colisionador franco-suizo de hadrones. Así que hay algunas anécdotas, planteamientos y conjeturas que ya perdieron sentido o que ahora son hechos irrefutables. De cualquier forma sigue siendo una gran obra que recomiendo a aquellos curiosos que no se han decidido a navegar en las aguas de la física cuántica. :)
