Format:Paperback
In this superbly written book, Michio Kaku explains it all and "solves" it all by the theory of hyperspace. Basically, it explains the futility of unifying the basic forces of nature in the present concept of 4-D space-time. In fact Albert Einstein had to add the fourth temporal dimension of time to explain the field theory of gravity. Later Theodr Kaluza, while expressing Einstein's field equations in five dimensions came to startling result in which Maxwell's field equations of electro-magnetism was included along with field equations of gravity. So, just by addition of one dimension, two fundamental forces of nature were getting unified. Much later the 11-dimensional supergravity theory encompassed all the forces as well as matter in its expression giving hope of the ultimate theory in offing. It was eventually abandoned because the equations were nonrenormalizable (nonsensical results). Of course, the latest offering is the 10-dimensional superstring theory and its successor the 11-dimensional M-theory. These theories are very promising, seeming to unify quantum theory and general relativity and steering clear of the troubles which beset previous higher dimensional theories. In fact, according to Kaku, at the instant of creation our universe was a 10-dimensional supersymmetric universe with all forces and matter/energy unified into one entity!
This book also delves into the origin and history of higher dimensional concepts, explained lucidly and brilliantly by Mr. Kaku. He explains that higher dimensional objects couldn't be visualized by us(3-D beings) and thus has to be viewed as projections or shadows on our 3-D space or even unravel them in our space(like a "tesseract", which is an unraveled hypercube). Kaku often drives home his point by explaining in terms of 2-D "flatlanders" existing in our 3-D world, which no doubt is a very easy way of understanding these kinds of concepts. This book will also explain theories regarding parallel universes, black holes, worm holes, time travel and death of our universe.
I definitely recommend this book to those who want to have a glimpse of the future and understand and enjoy the various physical concepts which are being brought from the realm of science fiction to our present day reality.

This book mainly deals with the 10 dimensions of the string theory.
I will start my review with the minor drawbacks of the book. First of all it is quite old. 1994 is 15 years older than our era, witch is quite a lot of time for science. Secondly, i dont want to sound like an arrogant but for me this was the 11th book of popular science that i've read, and to be honest it rarely said anything i didnt already know. Some people said that it got into to many details. On the contrary, i believe that it lacked some deeper details for the more enthousiast reader. But that's all the drawbacks i could think of.
The book is superb! I read it in 3-4 days, it is quite a record for me (i am not native english speaker), and that alone shows how addictive it was. It is highly enjoyable, very well written and very makes you visualize in your mind in a exciting way various terms, such as the topology of space etc. All the terms are extremely well analysed to the point that you feel it is like a fairy tale. I guess that for an unexperienced reader in popular science, reading this book will be a major philosofical shock. Learning for the first time about the double slit experiment, parallel worlds, topology of the universe is not an easy think!
Michio Kaku is an exceptional writter.

As an undergraduate physicist, this book has reminded me why I chose the subject!
Kaku's book takes you through all the ideas that have been put forward about multi-dimensional space in a fascinating way. Adding extra dimensions to our universe, instead of the usual three of space and one of time, has amazing consequences. It can unify all the forces in a beautifully simple way, enable time and space travel and maybe even explain paranormal phenomena! The chapters are split down into subheadings and this makes the physics a lot easier to digest.
'Hyperspace' is so enthralling it is extremely hard to put down. It has just the right balance between science and entertainment that makes it perfect for all to read. The ideas within this book really stretch your imagination to the limit and you will find yourself talking about the ideas to others. I would recommend this book, and Kaku's others, to anyone.
