Default accelerating universe conundrum, help me find my logic flawplease

Okay, so here we are for the moment in a RF that's

OR,

we're just looking at a small galaxy and a huge
galaxy in an area of space for which the volume is
uniform throughout...

Even way out here in this outside RF, how would we
know?

Well, assuming both galaxies are relatively close by in their
supercluster, the volume and PDT value of space in which they reside
would be uniform. Then you'd look at how far back in time the
supercluster itself resides. See graph -

If it's *far enough* back to where the cosmological PDT value is
beginning to really steepen, then the spatial volume will be
contracting concomitantly with it. You're simply "playing the tape
backwards" of the thinning and expansion of space on the cosmological
scale.
