I’m not sure that this book is entirely successful in answering, or even trying to address, the question posed on the cover — why is the universe just right for life? It talks a lot about how the universe may have formed, and what the laws of the universe are, and it seems like it does a lot of describing rather than explaining. Now, of course, that’s because we don’t really have an answer, but it does seem a little misleading.
Davies looks at a lot of different theories here, some of them more scientific than others — he includes the philosophical side of things too, including the religious point of view. He’s fairly even handed about this, so it’s hard to tell exactly where he’d put his money most of the time (except that he’s generally sceptical of the religion explanation, because it’s a non-explanation: it just shunts the question up a level). Most of the explanations are clear, though string theory remains utterly baffling to me (or at least, the rationale behind it does).
Oddly enough, I’m left feeling that The Goldilocks Enigma is much more positive about the idea that other intelligent life is out there than The Eerie Silence. I haven’t looked at publication order or anything, but it was a little strange, reading them one after the other.
Regardless, this was written before the Large Hadron Collider swung into action, so no doubt it’s out of date in some ways. Still a good background in the various theories, particularly the more philosophical ones like the anthropic principles that aren’t likely to change. (To his credit, I now understand the anthropic principle a lot better than I did after GCSE/A Level Religious Studies. Sorry, Mr B.)
