Yeah. So?
That's what I'm saying. A tiny,
tiny volume of (barely) energetic space is being added at every point in space throughout the universe. It's
like it's coming out of another "dimension," and it can certainly be modeled as such, but I think it's as likely that it is just a quality of the space we inhabit, still "hot" after the goings on in the very early universe.

My "verbal model" addresses current expansion, which can only
add to existing voids, not create them in the first place. For that, the bets are on an early period of hyper-rapid expansion (apparently from
very energetic space), which expands the quantum fluctuations to the sizes of the temperature variations on the CMB. That lays the foundation for the subsequent gravitational conglomerations.
