Lawrence M. Krauss, a well-known cosmologist and prolific popular-science writer, apparently means to announce to the world, in this new book, that the laws of quantum mechanics have in them the makings of a thoroughly scientific and adamantly secular explanation of why there is something rather than nothing. Period. Case closed. End of story. I kid you not. Look at the subtitle. Look at how Richard Dawkins sums it up in his afterword: “Even the last remaining trump card of the theologian, ‘Why is there something rather than nothing?,’ shrivels up before your eyes as you read these pages. If ‘On the Origin of Species’ was biology’s deadliest blow to super-naturalism, we may come to see ‘A Universe From Nothing’ as the equivalent from cosmology. The title means exactly what it says. And what it says is -devastating.”
Well, let’s see. There are lots of different sorts of conversations one might want to have about a claim like that: conversations, say, about what it is to explain something, and about what it is to be a law of nature, and about what it is to be a physical thing. But since the space I have is limited, let me put those niceties aside and try to be quick, and crude, and concrete.
In a backward northern country, people are accustomed to say, in such uncertain cases, “Fine. Whatever you say. See you on the ice tomorrow.”
