No bet I'm afraid. I'm happy to concede on this point. When I think about it further, it makes sense that space must not expand in zones where gravity keeps objects from separating due to cosmological expansion. As a very well educated non-physicist/cosmologist, I've had occasion to be wrong

It seems to me that differentiation is local, and spreads slowly, and that there is always going to be some remerging (but only in proportion to the chances of entropy reversing). The an atom starts in a superposition of decayed and non-decayed. Now a cat is in a superposition of alive and dead.
