A nice review article of his pronouncements against the theory:-http://www.uncommondescent.com/intelligent-design/physicist-paul-davies-killer-argument-against-the-multiverse/-"In addition to the reductio ad absurdum advanced above, Professor Paul Davies has other objections to the multiverse. In an interview last year on Closer to Truth titled, Are There Multiple Universes? (August 23, 2014), Professor Davies explained why he finds the multiverse hypothesis intellectually unsatisfying:- "It's not an unreasonable speculation. However, it falls far short of being a complete theory of existence, which it's often presented as. That is, if there's a multiverse, we can forget about all the mysteries of the universe because it's all explained: everything's out there somewhere. End of story. Well, it's simply not true, because to get a multiverse, you need a universe-generating mechanism - something has got to make all those Big Bangs go “Bang!” - so you're going to need some laws of physics to do that. All of the theories of the multiverse assume quantum mechanics, quantum physics, to give the element of spontaneity to make the bangs happen. They assume pre-existing space and time, they assume the normal notion of causality - a whole host of things. You write down a list, there's about ten different basic assumptions they have to make to get the theory to work. And you can say, well, “Where did they all come from? What about these meta-laws that generate universes and impose effective local by-laws, as Martin Rees would call it, upon these universes? What is this distribution mechanism? How does that work? Where do those rules come from? So all you've done is shift the problem of existence up from the level of universe to the level of multiverse. But you haven't explained it."
