Hi Alex
At the moment, we can't see back that far. JWST can see very far back into time, but only after the universe cooled and matter formed. We can see the afterglow of the plasma of course (CMBR) but that's it so far.
Why can't we see that far? Because there's a giant wall of plasma (i.e. no matter) between us and the "event". We can only theorise what was before the formation of matter and the CMBR helps a lot, but we can't actually see beyond that.
One area where the standard model breaks down is anywhere near infinity.. that is, a black hole or the birth of the universe. Whenever we see something "infinite" then it's usually a warning that something's wrong with the science.
