1979 isn't that long ago is it? Well, perhaps it is, but that doesn't excuse this. I love John Gribbin's popular science books so I thought that exploring one of his very early works would be a treat. Unfortunately time hasn't done this any favours and it seems very ropey. His thoughts on time travel are all over the place and based on books that don't seem to have much of a scientific pedigree. There are a couple of places where he picks up on the early 'many worlds' theories, but then he wanders into the realms of Jung and psychiatry and things go haywire. I really can't recommend this.

Substance: More popular than scholarly, and dated now. However, contains some interesting factoids, comparisons of science-fiction writings to reality, and some good story ideas. ( )
