Anyway, as I said, just idle speculation for fun.
How does the universe know it’s supposed to consider the positions on the entire circumference of a galaxy, and not just the “left” edge, or the left edge plus the center, or the right edge plus one quarter of another galaxy’s pinky finger, when deciding how strong gravity should be in the left edge? Only local information should be relevant, otherwise you’re back to assuming the universe respects our arbitrary boundaries.
You have a compressed gas, so, low entropy, then it starts expanding. The area where it started expanding has less possible states that the area around, but just because the area around is bigger, nothing to do with the relative position itself.
If the number of states are associated to gravity somehow, then gravity will be bigger the further you go from the center.
Because we are brainstorming in creative mode, I will add a bonus: if the number of possible states increase gravity, maybe, the older the universe gets, the bigger is that influence all around, accelerating its expansion.
I suppose that I will get my Nobel any day now ;-)
Not that this would affect California vs Rhode Island analogies, unless you could demonstrate that things in Rhode Island were a lot hotter...
