Chances are the big bang if happened, a lot older

Say the Andromeda is crashing with Earth. These are two nearby
galaxies.
In a billion years they will collide and the collision may last 3
billion years.

We have seen many collided galaxies in space. But yoyu take this
miniascule event taking place in a close proximity, and wonder how
could
the Universe be only 13.2 billion years old. Something doesn't nake
sense.

What if scientists were to pick a dark spot in the deep field picture
and
gather the faintest signals from that spot, then zoom up the picture.

The deep field picture was of 400-800 million years after the big bang.

Chances are that if zooming further, then one would arrive to a time
that was before the big bang according to calculations, and what would
they find? A picture of galaxies upon galaxies.
