@sonjorce okay, so: i am thinking about this stuff as it relates to the big bang. so even at a very very small time after the big bang, the stuff that is not inside the observable universe was already outside it? (i mean, not that we can know what it is, but if it is there, then it was)Permalink Look on archive.org
Mood +2 🙂

@sonjorce because obviously if you wind completely back to the big bang, everything is in the same place, but that is before time started, so it's not like anything could be observed.Permalink Look on archive.org

@sonjorce it is weird to think of the observable universe as a thing that is limited in time as well as space, although of course that's the case. if you see halfway across the universe, that place can't be influenced by somewhere outside the universe, but it is also a long time agoPermalink Look on archive.org

@sonjorce (but that place, now, could have a different conception of the observable universe which includes places inaccessible to us. and this is kind of a geometric relationship which is not dependent upon the time we're observing - the same would be the case 1 second after BB)Look on archive.org
