You keep repeating this, but other theories imply that, yes it does, its
just that the force that makes the universe expand is *huge*, but weak.
I.e., its like 10 billion hand fans waving at a sail. That amount of
force *might* have the effect of making the boat move, but its effects
on a fly passing in front of any given fan isn't going to do much. By
the same token, gravity is sufficient, for now, to prevent any obvious
expansion of places where it dominates, but we are talking about an
expansion rate, where it dominates, of like 1 gazillionth of a
millimeter per billion years, or some absurdly small change. Small
enough that its not going to be detectable, using any known instrument,
until like 10,000 times to time its going to take for the sun to burn
out.
It rather depends on "which" of the current theories you look at, and
who is discussing them. There are a lot of attempts to fit the math
together to work, and none of them have a clear picture, so all we have
is approximate guesses. Some of what you say fits, some of it doesn't,
so its is possible that the universe will die heat death, by *very
slowly* being ripped apart, including atoms, but at a rate that will
leave 99.9% of all suns dead by the time it starts to happen anyway,
but, at this point, slightly less possible, according to some people in
the field, that matter will remain intact, but the universe will just
keep expanding at an accelerating rate.
