The first half of the book was reasonably well presented, albeit very brief (most non-specialists would benefit from a lot more more background), but the remainder left me wanting. This is not a book for scientists, and unless the reader is willing to accept all that is said at face value, trying to find supporting information within these pages is largely futile (the motivated reader might search for such support elsewhere). And the punch line, that M-Theory (undefined) may answer all questions about the origins and nature of the physical universe, is pretty much left undeveloped. The book is nevertheless interesting if only to glean a bit of insight into some (pretty counter-intuitive) alternative explanations of reality.
