No . The visible universe is 13.4 billion light years . And according to the big bang, There is nothing past that time.
Except, What ever this huge thing is, we can not see. Matter and huge black holes do not jump behind the horizon faster than light speed.
There was almost certainly something BEFORE 13.7 billion light years ago
(; possibly, a hierarchy of turtles).
The "visible" universe currently observable by Hubble is ~13.1 billion years old.
The "visible" universe observable by JWST may be ~13.4 billion years old.
The actual "light visible" universe observable from earth is ~13.6996 billion years old.
- The "light visible" universe observable from earth
stops at the 3000K big bang plasma at z= 1,089 which
we now observe as (3000/1090)K cosmic background microwave radiation
from (13.7 billion yrs/10901.5) = 380,000 years after the Big Bang.
However, "The Visible Universe" is generally defined as the earth's own
~13.7 billion light years old event horizon left after the big bang inflation
whose current dimensions are calculated to be 46.5 billion light years.
Nothing within "The Visible Universe" is
currently being
influenced by something outside of "The Visible Universe."
That is not to say that something lying outside "The Visible Universe"
has not left an observable fossil imprint upon "The Visible Universe."
The casual speed limit of light was a meaningless concept during the big bang inflation period.
