Hi Tobin Dax

You mentioned that “ The self-gravity of planets, stars, galaxies, and even clusters prevent them from expanding as space does. Only intercluster space (well, maybe intergalactic space, to a smaller degree) expands via the Hubble law.”

Why stop the expansion of space at the boundary of galaxies? Why assume that self-gravity prevents stars and galaxies from expanding? Why not have the expansion of space-time be a unifying property of the universe? There is a lot of space with in galaxies, why not expand them. There is a lot of space within an atom, why not expand the atom?

So long as I provide a model for expansion that preserves celestial and atomic stability, what is the problem?
