So would I, A-G. It's just the cosmological picture forming in my fevered little brain conjectures that the vacuum is "intermediate" between us (physical reality) and its principal base (geometry) -- which base is non-corporeal, non-spatial, non-temporal, non-physical. The speculation is the primary vacuum facilitates or translates the expression of the non-corporeal realm as physical reality.
Of course, this is just a conjecture. The picture is not yet fully formed.... and if it were, it could certainly still be incorrect. :^)
"... my fevered little brain conjectures that the vacuum is "intermediate" between us (physical reality) and its principal base ..." Perhaps the 'vacuum' is a flux between 'past' temporal and 'present' temporal variable expressions of dimension TIME. Such a flux could be what 'pushes' the 'volume' of the physical universe.
