The LCDM model of cosmology fails another important test
I don't know if you caught that recent paper on quasar studies that was published recently, but it's definitely not good news for expansion proponents. Their expansion interpretation of redshift fails at higher redshifts. That's now the second time in as many decades that the expansion interpretation of redshift has failed to correctly predict the outcome of observations at larger distances.
When the SN1A data didn't jive with their predictions of a *decelerating* universe, they loaded up their expansion model with a hypothetical new form of energy that defies the conservation laws of physics. It was bad enough that dark energy needed to remain at a constant density throughout the expansion process to explain the SN1A data, but to explain the new quasar observations, dark energy would actually have to *increase* in density per unit volume throughout multiple exponential increases in volume.
It can't even be associated with a "constant" in a GR formula anymore, it would have to be an *increasing variable* now. Dark energy is the ultimate free energy machine. Imagine if I told you that the more dark energy that I used to fill up a piston to produce power, the more dark energy I had leftover after filling it up? Would you believe me? Science routinely rejects free energy machines for violating conservation of energy laws, but somehow dark energy gets a free pass. It's getting even more unbelievable by the decade.
On top of all that, the dark matter claim struck out three more times in three different and unique DM experiments just this week alone:
Three strikes for dark matter theory this week, and it's only Tuesday.
Between the quasar study and the DM experiments, the LCDM model is literally falling apart of the seams now, and they simply do not wish to discuss it.
I really don't think that the LCDM cosmology model will survive the JWST telescope era. Assuming it keeps finding 'mature' galaxies at even higher redshifts like Hubble, there just won't be anywhere left to hide anymore. The lack of useful predictions and the incorrect predictions are killing the LCDM model as it is. I certainly don't see it getting any better once the JWST comes online. JWST will probably see mature galaxies for as far as it can see too.
The "bait and switch'/equivocation fallacy routine related to Doppler shift isn't the only slight of hand being used to promote the LCDM model. Edwin Hubble personally preferred a static universe and tired light solution to explain redshift in space later in his life, yet astronomers, astronomy papers, and astronomy shows on TV routinely (falsely) claim that "Hubble proved that the universe is expanding", a claim that Hubble himself didn't even believe to be true. They also assert that GR theory predicts singularity type black holes when in fact Einstein rejected that idea. Hannes Alfven referred to magnetic reconnection theory as "pseudoscience' too, but you'd never know that by listening to the mainstream or reading their papers. There seems to be quite a few ethically 'questionable' statements which are used by the mainstream when promoting the LCDM model, and the Doppler shift equivocation fallacy is just one of them.
That really shouldn't be the case. LCDM proponents should be able to sell their model based on real empirical physics, but unfortunately they don't have a lot of real empirical physics to offer.
IMO the worst part of the whole redshift problem relates to the way that the mainstream handles the 'tired light' alternative explanation of redshift which Hubble preferred. They actually have no published papers to offer (well one by Fritz Zwicky when he was promoting his own tired light model 50+ years ago) on the topic of tired light alternative explanations of photon redshift. Instead, they constantly cite an unpublished website by one guy (Ned Wright) who in turn only references one actual published paper on the topic, that one and only one tired light model paper by Fritz Zwicky from more than 50 years ago. When promoting his own tired light model, Fritz Zwicky pointed out that one type of inelastic scattering, specifically Compton scattering, probably wouldn't fully explain cosmological redshift without "blurring" the images at higher redshifts. Never once did Zwicky mention any other known mechanisms of redshift, just Compton scattering, and Zwicky only did that much so that he could try to justify and promote his *own tired light explanation* for redshift. The astronomy industry has *never* done an exhaustive study of all the known types of inelastic scattering to find out if they would or could explain cosmological redshift. They simply handwave away tired light alternatives, and cite unpublished references to try to support their handwavy arguments. Keep in mind that tired light explanations of redshift do *not* violate conservation of energy laws like dark energy. Any loss of momentum by the photon is simply transferred to the plasma medium and all energy is conserved just as we would expect. If you read that quasar thread, I cited Chen's empirical lab work with plasma where he showed an empirical correlation between the number of free electrons present in the plasma and the amount of plasma redshift that he observed. There is a simple empirical explanation for photon redshift which A) works in the lab unlike the "space expansion" claim as to cause, and B) violates no laws of physics like the expansion explanation does.
The amount of mental gymnastics required to support the LCDM model of cosmology is simply off scale. Not only does the LCDM model violate conservation of energy laws, it fails large redshift observations galore. and it's failed every laboratory test of the exotic matter claim to date.
I think that's why we end up with equivocation fallacies being misused to support the model. It just doesn't have any empirical support to offer.
