I'm fascinated by the way this book provokes either a 5 star response or a 1 star response, with nothing in between. I''m a five-star fan myself, and I think the reason for the dichotomy (hem hem, as Molesworth would say) is that John Gribbin is so careful to get his facts right and to spell out what he means by words like "model." If you don't care and just want an easy but sloppy read, this might annoy you. But if you want the real stuff and proper science, there is nothing better. For as big a subject as the universe, of course it makes sense to start by spelling things out. And why shouldn't red shift come in where it does, if that's the proper place? I'm sure my views wont win any converts, and no doubt John Gribbin would aggree that any publicity is good publicity, but I just wanted to get this off my chest.
