Ross Andersen interviews Lawrence Krauss (who may be obliquely referring to David Albert's review), in The Atlantic:
Your book argues that physics has definitively demonstrated how something can come from nothing. Do you mean that physics has explained how particles can emerge from so-called empty space, or are you making a deeper claim?
Krauss: I'm making a deeper claim, but at the same time I think you're overstating what I argued. I don't think I argued that physics has definitively shown how something could come from nothing; physics has shown how plausible physical mechanisms might cause this to happen. I try to be intellectually honest in everything that I write, especially about what we know and what we don't know. If you're writing for the public, the one thing you can't do is overstate your claim, because people are going to believe you. They see I'm a physicist and so if I say that protons are little pink elephants, people might believe me. And so I try to be very careful and responsible. We don't know how something can come from nothing, but we do know some plausible ways that it might.
But I am certainly claiming a lot more than just that. That it's possible to create particles from no particles is remarkable—that you can do that with impunity, without violating the conservation of energy and all that, is a remarkable thing. The fact that “nothing,” namely empty space, is unstable is amazing. But I'll be the first to say that empty space as I'm describing it isn't necessarily nothing, although I will add that it was plenty good enough for Augustine and the people who wrote the Bible. For them an eternal empty void was the definition of nothing, and certainly I show that that kind of nothing ain't nothing anymore.
But debating physics with Augustine might not be an interesting thing to do in 2012.
Krauss: It might be more interesting than debating some of the moronic philosophers that have written about my book. Given what we know about quantum gravity, or what we presume about quantum gravity, we know you can create space from where there was no space. And so you've got a situation where there were no particles in space, but also there was no space. That's a lot closer to “nothing.”
But of course then people say that's not “nothing,” because you can create something from it. They ask, justifiably, where the laws come from. And the last part of the book argues that we've been driven to this notion—a notion that I don't like—that the laws of physics themselves could be an environmental accident. On that theory, physics itself becomes an environmental science, and the laws of physics come into being when the universe comes into being. And to me that's the last nail in the coffin for “nothingness.”
