If we look far enough out, we should see when the voids formed, and this
theory would seem to predict that each void would expand rapidly from a
central point. We aren't too far from testing this prediction I think.
Radical energy conservation seems a bizzare tendency to observe in *all* voids
across the universe. They obviously aren't hiding from each other, after
all. It would seem to imply they can't create new universes to explore, and
so realize that their local energy is all they'll ever have.
Having neutral zones full of visibly noisy galaxies also seems odd.
In neutral zones on earth, one tries to minimize activity so that it is easist
to tell if someone is trying to cross.
