I am not a GR expert. I have read that virtual gravitons which travel faster than the speed of light are responsible for black hole gravity extending outside of its horizon.

Now for us to feel the gravity of the entire universe, the virtual gravitons must have infinite velocity. Is that the case. Is it even correct to talk in terms of virtual gravitons. Is it correct to talk in terms of gravitons.

Rather than just saying I do not have a clue, why did you not say what the correct physics is.

In principle we can see sphere of diameter 30 billion light years in the universe. The distribution of galaxies within that sphere that we are able to observe is not uniform. Is that the large structure you refer to? How can it be uniform and have structure at the same time?
