This is a work of pure imagination. The author has come up with an imaginative idea (that does NOT meet the criterion for being considered a theory) about what comprises the universe we live in. This book claims that matter, energy and space are the same thing, with the particles we observe being 'knots' of space.

Unfortunately, his ideas simply don't work. When one creates even the most rudimentary mathematical model of his theories, one finds predictions that contradict what we know about the universe. Even without doing any math, it is possible to find errors and false predictions in his ideas based on simply finding the logical conclusions of his claims.

This book is self-published, after having been rejected by a number of publishers. I find it quite telling that even a company that would publish works by Deepak Chopra would turn down this author.

Duffield has been shopping this theory around the internet for several years now. In that time, he's been banned from numerous science forums for various reasons, including refusing to accept correction, presenting his ideas as established science, and even attempting to intimidate others by describing his claimed prowess at boxing and willingness to travel.

**In short, this book is a waste of time, for the author as well as any reader. I would recommend that anyone wishing to learn more about physics purchase a book by an actual physicist**.
