d region 400-800 million years after the big bang. I propose that
gathering faint signals from a dark region in the deep space
would reach space that is past the big bang. And what would
we see? I am pretty certain: Just a similar galaxies upon galaxies
picture.

You can not see time, before there was light! You may be able to push it
back to the first stars. if you had a REALLY big scope on orbit.

I am more ahead, I think, my eyes are not Hubble but I can see that
there was no big bang 13.2 billion years ago, if there was it happened
a lot more time ago.
