That is the natural prediction of these things, but I believe OP was looking for some specific, graphable differences to support the idea that these things in distant space do actually exist and evolve dynamically. The alternative implies that these distant constructs are either static projections, or somehow exist outside of our bubble of time.

While the thing you said about change at the macro level is spot-on, good science means we must use data to support these understandings, or else we must reject them entirely.
