My rating: 4 of 5 stars
I enjoyed this but of course I'm a layman -from outside, the idea of the various types of parallel universe posited here seems almost absurd, a sort of mathematical game. Greene goes some way to explain how some of these ideas could make sense and perhaps be proved (to the extent that positing the existence of realms of reality -sorry- that are completely inaccesible to us could be done at all). One little point: he tries to put together arguments for and against each of these postulates (and of course, again, many look very reasonable but I haven't got the tools to judge) but he seems to put a bit more weight (and expound much more at length) in the arguments for than against. A good read nonetheless and one that offers breathtaking vistas and thoughts on what may be reality and the universe(s).
