Prior to Big Bang

I don't think it will be long before we are able to see the Big Bang. At
least it is theoretically possible. My question is ... Will we, at least
theoretically, see before the Big Bang? What do you think we will observe?
Thanks in advance.

Cordially,
west

It is unlikely that we shall ever "see" the universe
at the moment of the Big Bang, as it was entirely
opaque to radiation prior to the matter-light
decoupling era (the Cosmic Microwave Background is
a relic of this era, being the radiation that
first escaped from its "confinement" at that time).

Neutrinos probably decoupled prior to light, so we
may get somewhat closer by detecting the Cosmic
Neutrino Background (CNB), but not all the way back
to the first instant.

As to seeing back further than the initial event,
you'll need to come up with a whole new theory that
decouples time from space; both space and time were
supposedly created at the first instant, so there's
no way to talk meaningfully of what was happening
"before".

I don't think we are going to see the Big Bang unless time gets compressed
between us and where it was, somehow.

This is because the light from the Big Bang is likely far beyond the
universe by now.

If time gets compressed, though, maybe we will see the Big Bang, soon.
As to how it gets compressed...it would be by whatever means that we are
seeing galaxies that existed just before the Big Bang...if in fact we are.

If time compression happens, and we do in fact see the Big Bang,
I see no reason at all why would not be able to see things before the Big
Bang.
Time is linear, after all.
What will we see?
I like you can hardly wait.

would it not be so ,that light goes in a big curv?
then it would mean ,that as we look further and further back in time,
that we would eventually see our own galaxy,yes??

IOW ,i don't think we will ever see the BB,not as long as we can perceive
only 3 dimensions,
and that is the case so far,

but don't despair, we can still perceive the remnant of the BB,the so
called,background radiation,about 3 kelvin

The longer light travels the more it is red shifted
due to the expansion of the universe. Even if the
topology of the universe turns out to be closed, light
would never be able to make the circuit; it would be
shifted to undetectability by the time it reached
our cosmic horizon. Another way to put this is that
the distant parts of the universe, everything lying
outside our cosmic horizon, is moving away from us
at greater than the speed of light.

yes ,that is true,
ofcourse , that part of the universe which is leaving us faster than the c ,
we can not see and never will,

but where is the prove,that such a part of the universe exists,
where it the prove,that something goes away from us faster than c? we assume
that!
and where is the proof,that light (what left us) is undetectable before it
makes its round,and comes back to us.

The universe was much denser and hotter in the past,
and the conclusion is that it is expanding. Given the
measured rate of expansion (Hubble constant) we know
that there is a cosmic horizon.

Also, if the universe was not expanding, we would
still be receiving light at the "temperature" of
the BB from regions far away. We don't.

that all is logical,
but,

the BB started in a point here onder my finger on my keyboard,but also
under yours and for that matter at the other end of the universe , so there
is no centre,or
everywhere is the centre,for us the cosmic horizon is in an other place than
for those at the other end of the universe,
what is going on?

Every observer has his own cosmic horizon. An observer
located halfway to our cosmic horizon can see further
past it (by the distance between us and him). It's
much like the Earth's horizon, where it's always
located at the same distance from a given observer.
