"Local spacetime is bound by gravity. There is enough mass in your average galaxy to create a gravity well that prevents expansion. Molecules are even more absurd."

Flamboyant, ridiculous supposition on your part. Shame on you.

You have no evidence, no proof, not even a *hint* that Gravity prevents the fabric of space, dimensions themselves, from expanding in local areas...yet you spout such rubbish as if it was fact. It's not.

Nor can you even show a Force that *is* causing Space to expand.

Shame. Shame. Shame on you.

You really need to study GR and SR.

You have no idea what you are talking about.

the fabric of space, dimensions themselves

There are three dimensions

Time, people, and dinner.
