(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
instant on the galatic scale (see also: Relativity). and so by the time
WEBB or any other other telescopes s mirrors cameras and blah blah blah
send that to our eyes those photons are now old reeely old. And the grand
expansion is fast enough to go faster then light? or is it because the
universe is stupendously big. so it takes a while to get to where we can
snag some photons?
