There are only two kinds of redshift. GRS and DRS. Though if you wish, we could divide DRS into two categories; localized Doppler redshift due to localized (non-expansion) velocity and the other; ‘cosmological’ redshift, due to recessional velocity per expansion in the current EU model. I actually think it should be divided into two categories. Doppler redshift is what is presumed to be the Hubble expansion factor. I presume it is due to GRS at the cosmological level. That is what I wish to debate. Or do Taylor and Wheeler show the only example of GRS possible?
GRS and DRS is all there is, and ever was, let’s not make it more complicated than it is.
HST does not need 10,000 years to measure the current redshift of any cosmologically significant object (don’t be silly), but to actually witness any measurable change in the redshift (per EU predictions) or actual change in location (per EU prediction) it would take about 10,000 years. Our currently published accuracy rates of measuring distances at cosmologically significant distances (cosmologically red shifted objects) are far too inferior to measure such changes in the few decades we wish it could be done. If it could be directly observed that would be helpful, but as yet, we do not have the technology to see this in action, period. If you would like me to run through the math at some point I will, but it is not observable with any other method than the one we have been using; i.e. the spectrum. One method is not sufficient when there are other possible other explanations like GRS to explain cosmological redshift, IMHO
I don’t really have to explain “why the light coming from Andromeda wouldn't have a cosmological redshift component?”, because it doesn’t and is not far enough away to help discover anything regarding cosmologically significant objects. It is moving toward us at 121 kilometers per second, so it is blue shifted in the spectrum. This would be localized Doppler shift and shows a velocity toward the observer, us. NGC 224 has no cosmological significance whatsoever, unless the universe is about to collapse right here.
From NASA,
“Theorists still don't know what the correct explanation is, but they have given the solution a name. It is called dark energy.”
“More is unknown than is known. We know how much dark energy there is because we know how it affects the Universe's expansion. Other than that, it is a complete mystery. But it is an important mystery.”
From WIKI,
“In physical cosmology and astronomy, dark energy is a hypothetical form of energy that permeates all of space and tends to accelerate the expansion of the universe.[1] Dark energy is the most accepted hypothesis to explain observations since the 1990s that indicate that the universe is expanding at an accelerating rate. In the standard model of cosmology, dark energy currently accounts for 73% of the total mass–energy of the universe.[2]”
I did not make up Dark energy, the scientific community did. Dark Energy is a hypothetical form of energy that makes up the math that does not work within our current EU model. Not my idea, but the scientific, peer reviewed, community. It sounds as though you know better than them?
World views are of no interest to me as it involves this subject.
