According to the current paradigm the universe is either expanding or contracting (It is dynamic) in a Hubble flow and therefore a 13.7 billion LY-380,000 yr's for the CMBR radius in our sphere. Also the universe is finite but unbounded.
When we look at our section of the universe (some 13.7 billion LY's) we see everything expanding away from us, and supposedly this started from Cosmic BB naked singularity, that also supposedly happened everywhere at once (which is unfalsifiable by itself, in other words without falsifying the whole theory).
When you look at the CMBR, in our 13.7 LY radius, the universe is either expanding or contracting with earth or the Milky Way, whichever you prefer at the center. SO, if the universe were contracting, the whole universe would be contracting to us.
Now, since the universe expanded everywhere at once from a point, when you go to a place 50/100/150 billion light years away, they would see the same CMBR there as we do here, right?
SO, if the universe is contracting, where is the gravity causing the universe to contract to?
In other words, the galaxy 100 billion light years away sees their CMBR and according to them the whole universe is contracting on them, right?
It certainly doesn't seem that this is a frame dependent scenario and that the universe is either contracting there or it should be contracting here. Which is it???
