Citing back to Owen:
Gil is right. The universe could be infinite, and it is at the least big
enough that we have no positive evidence so far that it isn’t infinite.
If it were infinitely large, but only finitely old, then at any given place,
the only photons that could yet have sped past us
Hmmm. Are we? I am skeptical it is. Ok so if it's not...how would we even
check? Gravity lensing and guesstimate?

AH! egad, that's so large and far away I can almost get my head around it.
lol no wonder we want infra-red. that's practically going backwards by then

They are shifted so far to the red that when they reach us, they are stop
lights.

(using a bad analogy) and those photons record what's going on like a on
going WEBB stream? so we now have essentially the ability to see old
streams (as it were) from photons any anything else that can get a snippet
of that. and basically light does take time to show up. it's not exactly
My guess: stars, including the Sun, are constantly producing and emitting
new photons. This happens as a result of fusion and other processes.

Same Q! My guess is what they meen is that stuff is reely far away so it'd
be like looking at events that had happened but we can catchup to the show
because of distance somehow due to lag essentially. Someone that knows more
about this then I do hopefully has a much more concrete answer. Fwiw
In aj NYTimes article:
https://www.nytimes.com/2022/12/27/science/astronomy-webb-telescope.html
..there is the usual discussion on "seeing back to the first several
millennia".
But, and be kind, why haven't these photons already sped past us? I suppose
it is because the exanssion is uniformly
