Long and involved, but interesting

Humans find it quite easy to grasp the idea of spacial dimensions. This might be because we have eyes, and skin that can feel things. If a clock was conscious, would it find space to be the elusive dimension? The author starts from the premise that time is inherently elusive, and he seeks to resolve this by eliminating it entirely. Inevitably, the notorious dual-slit light interference experiment features centrally in the book, as it does in Professor Deutsch's studies. Both of these quantum physicists are drawn to the multiple worlds (multiverse) theory, in which a virtually infinite number of universes exist simultaneously, 'touching' and affecting each other through the interaction of electromagnetic particles and probabilities. This theory is not accepted by the majority of physicists. Barbour's book is not an easy read; the early parts are far too long, and the conclusions - and the resultant implications - are not really clear at all. Having read the book, I certainly find it easier to imagine the universe existing as a timeless present moment, with no past and no future. Whether this book is on the right track, or merely leading its readers up the garden path, only the 'future' will reveal.
