Question Infinity or not infinity that is the question.

Harry, just to amplify a little.

Loving a marriage partner, is not the same as
Loving a parent or sibling, is not the same as
Loving a good friend, is not the same as
Loving a piece of music, is not the same as
Loving spaghetti bolognaise, is not the same as
Loving to watch a favourite TV program.

Having confidence in skiing, is not the same as (ability)
Having confidence in someone to keep an appointment, is not the same as (trust)
Having confidence in a newspaper, is not the same as (fairness)

Being a good friend, is not the same as (trust)
Having a good time, is not the same as (enjoyment)
Drinking a good wine, is not the same as (taste)
Making good time, is not the same as (punctuality)
Being good, is not the same as (behaviour)
Making good, (success)

There are many more examples, even if some of these refer only to shades of meaning.

For me, the confusion and discussion is not about context or definitions. It’s about the measurements.

You may believe that expanding space, taking galaxies with it, is causing those insane rates.

But it shows me that something is wrong. And it has to be the dogma of light, for that’s the only thing they will not consider.

Science has restricted itself with this dogma. And for the spacetime pure-est, this dogma is now impossible to either prove or disprove. And insist that velocity sets time and length.

I believe this intellect is of poor quality. It is more like a religion, then a science. With false relics.

Physics has become a philosophy now, instead of a science. A path for faith thought, instead of a path of discovery.

Just an observation. And the context gleaned from it. I believe redshift will be the greatest misunderstanding in science history.

And once that is cleared up, a new context for this cosmos will begin. A totally new cosmology.

Quantum light.

Of course the measurements are the bread and butter, but you then need deductions and hypotheses. These require words, with accurately defined meanings, which are the province of science.

May I point out politely, that, in some cases, you seem to have read the opposite of what I posted.

The recently launched James Webb Space Telescope (JWST) is opening new observing windows on the distant universe. Among JWST's instruments, the Mid Infrared Instrument (MIRI) offers the unique capability of imaging observations at wavelengths λ>5μm. This enables unique access to the rest frame near infra-red (NIR, λ≥1\mum) emission from galaxies at redshifts z>4 and the visual (λ≳5000Å) rest frame for z>9. We here report on the guaranteed time observations (GTO) from the MIRI European Consortium, of the Hubble Ultra Deep Field (HUDF), forming the MIRI Deep Imaging Survey (MIDIS), consisting of an on source integration time of ∼41 hours in the MIRI/F560W (5.6 μm) filter. To our knowledge, this constitutes the longest single filter exposure obtained with JWST of an extragalactic field as yet.

The research is covering 1.2 million Galaxies.
If the research covered the total sky, it would take over a million years.
The more we see out there the more complicated and more than we ever thought.
We see out there Millions of Galaxies before the so-called Big Bang.

And yet NASA said it all happened in a few million years.

Hybrid-z: Enhancing Kilo-Degree Survey bright galaxy sample photometric redshifts with deep learning​

We employ deep learning (DL) to improve photometric redshifts (photo-zs) in the Kilo-Degree Survey Data Release 4 Bright galaxy sample (KiDS-Bright DR4). This dataset, used as a foreground for KiDS lensing and clustering studies, is flux-limited to r<20 mag with mean z=0.23 and covers 1000 deg2. Its photo-zs were previously derived with artificial neural networks from the ANNz2 package, trained on the Galaxy And Mass Assembly (GAMA) spectroscopy. Here we considerably improve over these previous redshift estimations by building a DL model, Hybrid-z, which combines four-band KiDS images with nine-band magnitudes from KiDS+VIKING. The Hybrid-z framework provides photo-zs for KiDS-Bright, with negligible mean residuals of O(10−4) and scatter at the level of 0.014(1+z) -- reduction by 20% over the previous nine-band derivations with ANNz2. We check our photo-z model performance on test data drawn from GAMA, as well as from other KiDS-overlapping wide-angle spectroscopic surveys, namely SDSS, 2dFLenS, and 2dFGRS. We find stable behavior and consistent improvement over ANNz2 throughout. We finally apply Hybrid-z trained on GAMA to the entire KiDS-Bright DR4 sample of 1.2 million galaxies. For these final predictions, we design a method of smoothing the input redshift distribution of the training set, to avoid propagation of features present in GAMA, related to its small sky area and large-scale structure imprint in its fields. Our work paves the way towards the best-possible photo-zs achievable with machine learning for any galaxy type both for the final KiDS-Bright DR5 data and for future deeper imaging, such as from the Legacy Survey of Space and Time.
