Hmmmmm. The quantum background being the quanta that come in to being from the deepest kind of absolutely nothing? How many of these to a big bang? One? Where quantum gravity swamps, pre-empts general relativity making singularity impossible? I suppose I’ve been subconsciously, unexaminedly thinking of background quanta as openings, channels for negentropy. Erroneously, unnecessarily. But how do we get from minimal quanta of existence to pre-inflation, Planck epoch big bangs? Unless the minimal quanta actually define the big bangs? I dunno. Especially if the net energy has always been zero… nothing became more complex… nothing; everything cancels out.
