The James Webb Space Telescope has only been watching the sky for a few weeks, and it has already delivered a startling finding: tens, hundreds, maybe even 1000 times more bright galaxies in the early universe than astronomers anticipated.

Within days after Webb began observations, it spotted a candidate galaxy
that appears to have been shining brightly when the universe was just 230 million years old, 1.7% of its current age, which would make it the most distant ever seen. Surveys since then have shown that object is just one of
a stunning profusion of early galaxies, each small by today=E2=80=99s standards, but more luminous than astronomers had expected.

Well, this confirms what I have been thinking all the time since several years. Maybe there is no "Big Bang" but a gargantuan gas cloud that started to condense into galaxies 16, or 17 Gy ago.
Or maybe not, since we see the brightest ones at those enormous distances,
it is normal that we see the bright and younger ones. JWST has started observing a few weeks ago. Maybe we will find old galaxies at100 My after
the supposed "bang" soon. The current record holder that I mentioned in
this group was at 230 My and it is but one of " a stunning profusion of
early galaxies," See "On the stunning abundance of super-early, massive galaxies revealed by JWST" https://arxiv.org/abs/2208.00720
VERY interesting times.

Interesting contortion of logic here from the moderator. Because
erroneously the moderator is pretending that a non expanding model predicts *no temp difference* of the CMBR over distance!!
( Tell me something moderator...based on which published research did you come to
the conclusion that a non expanding model couldn’t predict a temp difference
of the CMBR?)
Looking at the conclusion section of one of the papers you cite (3), I notice
the supporters of the BBT suggest that the temp of the CMBR increases with increased redshift. In other words presumably they are saying that in an earlier
Big Bang universe where there was less expansion the CMBR would be hotter. And therefore also supposedly disproving any non expanding model. (?) However as usual from BB theorists this ignores what a non expanding CMBR would also predict at earlier redshifts.
Because in a non expanding model redshift of the CMBR is said to be,
by some theorists at least, a galaxies black body spectrum from great cosmological distances redshifted from the optical spectrum to
the microwave region. And using the inverse relationship over distance then it’s also true that energy , luminosity and *temp* of a redshifted CMBR would
also reduce over distance in a non expanding universe.
After all unlike the
BBT the non expanding model DOES like to,stick to,the accepted laws of physics.
Seems to me that the authors of the paper have not only just proven
that a Big Bang model can be verified using their analysis. But that they also
have concluded thatbnon expanding model is also verified by their analysis.

inappropriate for the newsgroup because it contains false statements.
In particular:

long since debunked),
the usual idea is that it is REPROCESSED to the
microwave region (e.g. absorbed and re-emitted by dust), not that it is REDSHIFTED. After all, such non-big-bang models typically don't have a cosmological redshift.
Because in a non expanding model redshift of the CMBR is said to be,You are probably thinking that objects further away are fainter. Yes.
by some theorists at least, a galaxies black body spectrum from great cosmological distances redshifted from the optical spectrum to
the microwave region. And using the inverse relationship over distance then
it’s also true that energy , luminosity and *temp* of a redshifted CMBR would
also reduce over distance in a non expanding universe.
Luminosity, as usually defined, is an intrinsic quantity, but maybe you
mean apparent luminosity. OK. In some sense the received energy is
less, of course. But the temperature is measured from the peak in the spectrum, which doesn't change just because an object is further away;
it changes only if there is a cosmological redshift.
Astronomers routinely measure the temperatures of stars, which are visible over a
very wide range of distances. It is something which can be measured independently of distance.
After all unlike theIf you are thinking of a specific non-expanding model which has a cosmological redshift, you need to cite the corresponding paper or
BBT the non expanding model DOES like to,stick to,the accepted laws of physics.
Seems to me that the authors of the paper have not only just proven
that a Big Bang model can be verified using their analysis. But that they also
