They're moving with the underlying metric. The speed of light is constant for all observers. That's what defines the visible horizon of the universe.

Those are the kind of thought experiments used to demonstrate the precepts of relativity.

If we could pause the photons from the other universe will still allowing our universe to expand, the distance from the photon to our location would not change at all.

I'm not clear, from reading the thread, just what you mean by "universe".

Let me try to illustrate how I view the universe;

Consider the universe as you would an atom. It has a spherical shape and is comprised of inward components. I don't believe the universe is perfectly spherical, but something closer to a blast radius. The "shell" or edge of the universe is not defined by where the ISM ends but rather how far matter is scattered throughout an infinite ISM. Now I want to clarify that when I speak of ISM inside the universe and outside the universe, there is a compositional difference. Since the end or shell is where matter ends, the black field that extends beyond the shell is devoid of particles or gasses. It is simply void.
