A decade or so ago, the mainstream "assumed" that LHC would help them find their beloved exotic matter. The reality however with LHC is that it utterly *crushed* their best dark matter models out of existence, along with the mathematical basis for their beloved WIMP models (SUSY theory). SUSY theory isn't just on life support anymore, it's dead and buried. WIMPS today really have no real mathematical basis for their existence, but they just won't die a natural scientific death. Of course there are "little Higg's concepts and extra spacetime dimension concepts' that also predict "WIMP like" particle, but SUSY theory was in fact the primary basis for WIMP claims, and SUSY theory went down in flames at LHC. Not a single new "sparticle' was produced or observed at LHC, and the standard particle physics model has proven to be extremely accurate at predicting even secondary decay processes with unbelievable accuracy. Every WIMP claim either requires SUSY, or it requires the existence of additional spacetime dimensions, or both. Axion and sterile neutrino concepts don't tend to work very well in the mainstream computer models, and they too have been studied and falsified by recent high precision experiments.
What started out as optimistic enthusiasm as it relates to dark matter claims a decade ago has since turned into a kind of dark matter zombie apocalypse. The dark matter concept won't die, even though the entire mathematical basis for the concept has been utterly destroyed. The mainstream makes such a big deal about their mathematical prowess, but they've struck out consistently in terms of their mathematical claims about DM. It's like being a mathematical expert on astrology. Sure, the math has value as it relates to the movement of objects in the sky, but their mathematical expertise is *useless* in terms of predicting events in the lab.
LUX-LZ, Pandax-III and Xenon-NT will push the WIMP interaction cross section with ordinary matter right down into the realm of neutrino interactions. At that point they'll be no way to distinguish between them. For all intents and purposes, those three experiments are the 'last hurrah" of WIMP theory. If they don't find anything (and we already know from the LHC results that they won't), then WIMP theory will have died a slow and agonizing death in the lab and even the WIMP zombies will be dead and buried. All this will occur over the next 5-7 years.
The next LCDM zombie apocalypse relates to quasars. They keep showing up further and further back in time, at higher and higher energy levels. Quasars should not have formed so "early" in a big bang universe. They keep defying all the mainstream computer models. Things will only get much worse when the James Webb Space Telescope starts returning images of the distant universe. Unlike Hubble, JWST will be able to probe a wider wavelength range which will let it see more distant galaxies and more 'redshifted' objects. It not only contains a larger reflection area, it has the ability to look much further due to it's improved wavelength sensitivity.
The mainstream already struggles to (doesn't) explain distant quasars as it stands, but as quasars show up at greater distances, it's only going to get worse for them. Unlike with LHC, I'm sensing and feeling enthusiasm for JWST but unlike with LHC before it started up, I'm not seeing any real confidence that JWST will "validate" the LCDM model. It feels like there's enthusiasm for the improvement in technology and enthusiasm for the new images the JWST will produce, but I'm also sensing some real fear and trepidation about what JWST might do to their cosmology model. It's not clear what exactly JWST will produce in terms of images yet, and I think they already know that. If it does keep showing the presence of massively energetic quasars even further back in time, and mature galaxies as far as it can see, it's going to create huge a dilemma for the LCDM model. The mainstream already has to resort to exotic 'dark stars" and absurd ad-hoc explanations to attempt to explain high redshfit Hubble observations, and t's only going to get worse once the JWST images start arriving IMO.
If photon redshift is in fact related to "tired light" rather than space expansion, then deep field JWST images should show us mature, well defined galaxies and massive quasars in it's deep field images, just as Hubble deep field images show us today. If however redshift is related to expansion as the mainstream claims, then galaxies and quasars should stop being visible beyond a certain redshift. It takes time for galaxies to form and to grow in the LCMD model. It takes quasars even more time to form in mainstream models. Quasars also happen to be the brightest objects in the universe, so they will be visible as far back in time as they exist, or that JWST can hope to observe. JWST will have the technology to quite literally blow the LCDM model out of the water in deep field images. If like Hubble, JWST also observes "mature' galaxies and massive quasars as far back in time/distance as it can observe, the party will be over for LCDM proponents.
Keep in mind that not only will the WiMP zombie apocalypse run it's course and be completed at the smallest scales by around 2025, the JWST should have returned images by then which blow away their claims at the largest possible scales. Astronomy is on track to experience a "quantum shift", and an epiphany experience over the next decade.
As LHC has already demonstrated, time and technology have been on our side, and it continues to be on our side. When you look however at where things are headed, the LCDM model is likely to be ripped to shreds within the next decade. If they don't find actual evidence of WIMPS in the next round of Xenon experiments, and they keep finding massive quasars in JWST images, LCDM won't survive another decade.
Personally I think that the jig will be up when JWST starts returning deep field images. I don't believe that the mainstream is emotionally or scientifically prepared for what it is likely to see in those images. I think even they know that there is a distinct possibility that JWST will blow their model away, which is why the enthusiasm seems to be somewhat muted by trepidation.
IMO, things are likely to remain as they are though about 2022-4 and then I think that all hell is going to break loose in astronomy.
I for one am really looking forward to JWST images. LHC and other experiments can and have already blown away their mathematical models at the smallest scales on the ground, but JWST will have the ability to blow away their model at the largest possible scales. Recent Hubble images are already pushing their model to it's limits, but JWST will leave them with no place to hide IMO.
