Far out cosmology (Introduction)

Your (DT and dhw) mantras that "There must have always been something" and that "Nothing can come from nothing" are where we disagree. -But we have discussed this before in the context of Victor Stenger's "Comprehensible Cosmos". -I am happy with the universe's origin being a state of "nothing" or "void" or maybe some other word is needed that doesn't have other connotations. -The "big bang" wasn't really an explosion - that was just a satirical name given to the theory by Fred Hoyle. I'm not convinced by the "inflation" aspect of the theory anyway.-The idea that there must have "always" been something betrays your inability to get the Newtonian idea of time out of your head. Time and space are measurable properties that only make sense within the universe. Once it contracts down to sub-Planck dimensions time and space have no meaning.
