Davies Temporal Gymnastics:
Paul Davies suggests that in a closed-time world, the past would also be the future. He thus opens up a prospect of temporal paradoxes, more frequently visited by science fiction writers, since H.G. Wells. But, if time joins up with itself similarly to a snake swallowing its tail, he proposes it would not be possible to distinguish forwards or backwards in time, just as he has explained, that there is no distinction between left and right hands in a Möbius-type space. Prof. Davies concludes, "Whether or not we would notice such bizarre properties of time is not clear. Perhaps our brains, in an attempt to order our experiences in a meaningful way, would be unaware of these temporal gymnastics."
Holes with Teeth?
As a Mathematical physicist, he expresses his Möbius-style thoughts, "Although edges and holes in space and time might seem like a mad mathematician's nightmare, they are taken very seriously by physicists, who consider that such structures may very well exist. Although there is no evidence for the mangling of space-time, there seems a strong suggestion that space or time might develop 'edges' which have borders, or Cauchy-Reinmann type contours, "so that rather than tumbling unsuspectingly off the edge of creation, we should be painfully and, it turns out, suicidally aware of our impending departure.Read more ›
The reason I don't give this book 5 stars is that it is one of Davies' earlier writings (originally published in 1980). I think he's improved over the years, and one of the best reads I've had from Davies is his "The Last Three Minutes." "Other Worlds" is a great read, but it never seems to achieve it's objective. At the onset, you're expecting to learn how alternate existences and parallel universes may exist or at least be explained mathematically, and if they do exist, what is their physical representation. To me, however, the whole point of the book is lost in deep explanations regarding electron paths and variances along those paths, etc. How these variances apply to "Other Worlds" is never clearly explained. At least to me.
Still, it's a Davies book, and they're very interesting to read. He puts scientific principles in layman's terms without insulting one's intelligence. Overall, I recommend this book, even though I'd recommend reading some of his later works first.
