To write a book about infinity is tough, and to review it is not easy either.
Broadcasting is strictly linear - you can't double back to re-hear a paragraph. You get it or your miss it. Turok does his best to catch the average curious mind with anecdotes and colorful metaphors, but I have to wonder how many millions of polite Canadians could genuinely grasp what he was on about from beginning to end. Even with the advantages of the book for, it was a tough read for someone with lifelong amateur curiosity into the general concepts of cosmology and physics.
If you do follow Turok, you will end up accepting thatour universe is expanding at an accelerating rate, having started as a microscopic dot of unbelievably compressed energy some 4-5 billion years ago. The expansion is probably powered by unmeasurable "dark matter" and "vacuum energy". It is not the job of physicists to ask why this happened, but they are increasingly confident that they know how it happened. Turok inclines to the view that our current expanding universe is just one instance of an infinite number of expansions, followed after a few billion years by contraction, and then another Big Bang to start the expansion again.
