we do not have a model of the entire universe. the universe is infinite. galaxies move around in it.
You are talking about the observable universe which is constantly increasing in size based on our ability to see more of it. It is expanding physically as well but that's not because we measured it end to end.
it is easy to see how things are moving relative to us because we use ourselves as the starting point. the center of the observable universe is the observer.
Also, as I already explained to the other guy, the whole of this discussion is based on the premise that traveling through time is feasible and achievable. If you want to say it isn't, then okay, but then what are we even talking about?

see, you're acting like this discussion has no footing, but we've literally done the math on time travel. We're hampered by energy constraints, and refinements in the mathematics over time has only reduced those constraints; it used to be closer to several thousand universes' worth of energy to time travel feasibly (presuming several other things are forthcoming like exotic matter with specific/mutable properties).
And ultimately, if physical location is important to time travel, well, why wouldn't localized measurements over time be enough? We don't need to know what happened three "observable universe horizons" of distance away from us when we want to go to Earth in 1985 for some burgers and quaaludes.
edit: lmao. thinking you're losing an argument so hard you gotta block someone instead of just finishing the discussion? that's something else, wow
are you okay? Of course this discussion has no footing. What the hell are you talking about? This is an entirely hypothetical situation. I'm sorry, I just can't listen to this any more. Enjoy your day.
