Reply to comment by skofan in 87 newly-discovered galaxies, found using Webb space telescope, could be earliest known galaxies in the universe — the first indication that a lot of galaxies could have formed much earlier than previously thought by marketrent

Ok I'm no physicist but why do we think space itself is fully contained within a bubble of what we can see? Isn't it silly to assume there's nothing outside our visible bubble when we always see more the further we look? How do we know it's space itself contracting and not just our portion of some much larger explosion?

I feel like maybe that's all explained well enough, but I also know scientists love to smell their own farts and word conjecture as fact.

We know it's space itself because everything appears to be moving away from us, personally.

The only two ways that's geometrically possible is if we are actually uniquely special and the center of the entire universe, or if everything is moving away from everything else. The second one is considered the only plausible of the two options.
