Thank you! Yes, that’s definitely interesting to think about. The long-term fate of the universe is another open question -- does it accelerate forever, could it collapse somehow, or cycle somehow? Physics seems to suggest that space will eventually just atomize completely, with individual galaxies or perhaps even molecules expanding beyond each others’ observable horizons. Or could some interesting new unanticipated structures arise, maybe at massive distances or ultra-slow timescales? The general question, I guess, is are we witnessing the long decline of a mature universe, or is it still in its youth?
