Question: If we can see some of the first ever galaxies that are no longer existent by pointing the Hubbell space telescope at a spot of sky for a lengthy time period, Is it possible that we could actually see the Big Bang if we pointed the Hubbell space telescope at the same position for an even longer period of time?

Yes but stephen, cant we see galaxies that are no longer existent through the hubble telescope?
yourmum commented on :
or is that just as you said about the big bang, an ‘afterglow’?
Stephen commented on :
I believe that’s right, youmum, we can’t certainly see very far back in time to things that no longer exist because the light took so long to reach us.
But the Big Bang was the very first visible event in the history of the universe (as far as we know – let’s leave aside what went on before that). I’m guessing that it’s simply too far back for us to have seen it – in other words the light waves reporting on this event have already passed us by.
But I could be wrong!
