Trying to make the cosmos out of nothing

“Krauss does want to deliver that blow: towards the end of the book, he promises that we really can have something from nothing – “even the laws of physics may not be necessary or required”. Ultimately, though, he has to perform a little sleight of hand. Space and time can indeed come from nothing; nothing, as Krauss explains beautifully, being an extremely unstable state from which the production of “something” is pretty much inevitable.

However, the laws of physics can’t be conjured from nothing. In the end, the best answer is that they arise from our existence within a multiverse, where all the universes have their own laws – ours being just so for no particular reason.”
