Still this assumption that there actually was a happening or occasion or whatever which is subsumed under that catchall nomenclature 'Big Bang'. I OPd a thread some years ago which ran&ran&ran for a good while, asking simply "What went Big Bang?" I don't think a satisfactory answer [or indeed any sort of answer] in fact emerged. It's a copout concept, not much more useful than "God", SFAICS.
