Two Red Shift Predictions
I have two predictions about red shifts. As both apply to the future neither can be confirmed. However they can be debated using just logic. Such a debate brings up problems in cosmology.
1) There is no limit on Z the factor of the red shift in the hydrogen atom absorption line wavelength being measured from distant galaxies.
2) If we viewed the universe from another galaxy we would perceive us at the new center of the expanding universe, just as we see the Earth now at this center of the expanding universe (or the site of the big bang).
The basis for both predictions is the initial observation in the 1930's that the red shift measured in the hydrogen atom absorption line in a galaxy spectrum is proportional to the distance of that galaxy.
Cepheid variable stars in galaxies enabled calculating a distance to that galaxy, so it could be determined by another mechanism. This resulted in Hubble's Law for red shift to distance.
Eventually some scientists proposed neutral hydrogen atoms in intergalactic space could result in this observation.
This theory appears to be confirmed by observations like the Virgo Centric Flow where different galaxy clusters apparently have a different density of neutral hydrogen atoms resulting in a different ratio for more or less red shift.
Therefore the Hubble Constant could vary by direction depending on intervening galaxy clusters.
This theory also appears to be confirmed by galaxies seen to be more distant appear to have more red shift because of the greater distance, through more intervening atoms in space.
Regardless of the physical mechanism for this particular absorption line wavelength to shift (I have seen alternate theories) the red shift to distance rough ratio continues to be observed.
The justification for prediction (1):
As our technology improves we are able to image ever more dimmer objects. As light dims over distance we are seeing objects more distant than before and so the red shift can be increasing. This is due to the red shift to distance relationship.
These observations lead to the very annoying news stories about the 'most distant' or the 'fastest object ever observed. This observation of increasing red shift also results in the ridiculous 'expanding fabric of space' claim that is now widely accepted.
The limit on the Z red shift is based on our imaging technology for what is the dimmest object that can be observed and so that is both the distance limit and the Z limit.
There is no actual limit when its value varies only by technological advances.
If the universe is finite only then there is a limit.
If the red shift to distance relationship is falsified then this prediction has no basis.
The justification for prediction (2):
All objects in the universe are radiating their light in all directions.
All observers in the universe, wherever they are in whichever galaxy, will see all the distant galaxies red shifted by their distance. Each observer, unless they avoid the stupid mistake made by Earth's cosmologists treating a red shift as a velocity, will see themselves at the center of the expanding universe and at the site of their own big bang though they are not at the site of the center seen by all the other observers.
