The universe was before the "Big Bang"

Many scientists believe that the universe originated from the
"Big Bang" (https://bit.ly/3DCD7JE). However, physicist Brian
Cox stated that the universe existed before this event. According
to Professor Cox, there was a time before the Big Bang when the
universe actually existed. Then, 13.8 billion years ago, the
universe was a small point where everything was much closer
to each other.
Before the "Big Bang" matter did not exist, and there was only an
ocean of energy, almost motionless, but slightly swaying. Professor
Cox says we must "imagine it as a motionless ocean of energy
filling a void." Although there were no structures in this place, the
energy acted on the space, causing it to stretch.
In 2020, astrophysicist Roger Penrose stated that the Big Bang was
not the beginning. Something happened before the "Big Bang", and
this something awaits us in the future. We exist in a universe that
is expanding, then all the mass disintegrates, and the distant future
turns into the "Big Bang" of another era. The astrophysicist
believes that he was able to detect fragments of the past Universe,
which are "dead" black holes. There are six of them, they are well
warmed up and eight times the diameter of the moon.
