Is there a name for the type of momentum that leads to the expansion of the universe? Or is that just the total thermal energy that will become entropy at some point?
“Dark energy” or “cosmological constant” is what “pushes” the universe to expand. Not angular momentum, which is, according to our understanding is zero. By the way, it is the space itself that expands. There is no any “expansion force” that acts on stars.
Last time I checked, universe does not rotate at all, its total angular momentum is zero.

We proved the no(-ish) angular momentum bcs of spacetime flatness, then we proved local unrealness.
And what about the angular momentum of the multiverse?
Why it would be any different in multiverse? The it is highly unlikely that the pure initial state had any angular momentum.
What is the universes themselves suspended in some sort of field are orbiting some pretty petunias?
In that (quite convincing) case, it still doesn’t revolve around you, unless you are that petunia.
