So in other words, local gravity effects actually keep local *space* from
expanding? If so, that's a new concept for me; I thought space itself--whatever
it actually *is* ;-) --was sort of 'independent' of gravity, expanding at its
own independent pace, as its own 'entity.' Although, now that I think of it,
"gravity warps space," so what you say isn't so weird after all. Geez, that's
always been a difficult concept to grasp. But is 'new space' actually formed? Or
is it just 'stretched' (whatever *that* concept means)?
