I know Krauss' position and he has been laughed at by a number of philosophers. He thinks getting a universe from a quantum perturbation in a virtual quantum vacuum is something from nothing. A spacetime quantum vacuum with things poppng in and out of our existence is not nothing. Nothing is an absolute void, which I believe has never existed. There has always been something to answer Leibniz' question.-Ahh There are philosophers who are knowledgeable about nothing that laugh at Kraus.-OK that is a definite play on words.-But similarly ... my view of god is as valid as yours, GKs or DHWs.-The mistake philosophers make is they entertain metaphysical concepts ... like the nothing that (your) philosophers laugh at. My philosophers would take Kraus's idea with interest.-And this takes me to the question (Simon Blackburn's) I mentioned before ... Why is nothing our default state?-Nothing is an absolute void Ignoring the play on words that is available to me ... a valiant attempt, but a fail in my opinion.
