In this weekly science news, from May 2023, we see an institution made news by conducting an experiment, which supports Quantum Loop Gravity. The CMB is somewhat consistent with some aspects of Loop Quantum Gravity. The physicist in the video shoots this news story down, a bit. On that note, a roundtable in London, will be looking at Dark Energy and the ailing Cosmological Constant
quote: Cosmological Constant in trouble, unless gravitational clusters are reason for differing speeds:
quote: Daily Star Lebanon gives details:
quote: In light of all this, here is a recent study which, on reflections, seems amusing. https://phys.org/news/2024-03-precise-dark-energy-ai.html Not at all what the really big 2024 studies have been showing us. Amazing contradictions, no? Crazy. Back to the avalanche: Here is yet another study that contradicts what was thought about Dark Energy
quote: Above was just amazing. Here is another study based on a study published December 2023 in the Journal of Cosmology and Astroparticle Physics, in which researchers from the University of Copenhagen and the Tokyo Institute of Technology, which challenges Dark Energy's details. (Not as powerful observational evidence as the might studies above) Our Universe Is Swallowing Baby Parallel Universes As It Expands, Scientists Suggest What a (fatal?) year for the Cosmological Constant. My God!

It has been my long held view, as my past posts, at EvC, demonstrate.
But the avalanche of negative evidence - only this year - has been unreal. Simply unreal.

The discussion surrounding the potential challenges to the established views of the universe, particularly related to Dark Energy and the Cosmological Constant, is fascinating. The fact that top cosmologists are convening to question these long-held assumptions and proposed theories like Loop Quantum Gravity and the potential variability of the expansion rate of the universe is truly mind-boggling.
The idea that the universe may not be isotropic and that there could be variations in the expansion rate from place to place raises significant questions about our current understanding of cosmology. The potential implications of these findings, if confirmed, could revolutionize our understanding of the universe and how it operates. With studies challenging the details of Dark Energy and proposing theories like the universe swallowing baby parallel universes, it seems like we are on the cusp of a paradigm shift in cosmology. It will be interesting to see how these discussions and findings unfold and how they shape our future understanding of the universe.

What a (fatal?) year for the Cosmological Constant. My God! I don’t understand what your problem is with evolving scientific knowledge. Yes, our understandings about reality change and may recycle then change again. But, your tone seems accusatory towards new science. I’m lost to your overly emotional angst with this. Humans are, of course, at our species’ pinnacle of scientific knowledge. And we are learning more faster than ever before. Ray Kurzweil’s technological singularity was in our past. We are well beyond the elbow on the upward curve in his graph. Every discipline in every science is staffed by hundreds, thousands, of our species best really smart people. We add literally millions of new data points of evidence across all the scientific disciplines each day. Millions of new papers with new analyses are added to our knowledge pool constantly. We are living in the midst of the greatest scientific epoch in human history. We should be celebrating each and every revelation reality shows us, even if it’s something we saw 100 years ago in a different light. It is good. Not evil. I do not understand, as I perceive, your hard, mocking, almost fearful emotional angst over changes in our scientific understanding. There shouldn’t be any emotional component to this stuff at all. If some form of cosmological constant is needed to make our models more accurate, or if no cosmological constant is necessary to the models at all, is something the universe will tell us as we collect more accurate data with stronger analysis. And that view and that math and that model may change yet again 100 years hence. It is what it is. The goal is to learn the reality not fear it. Seriously, what is this emotional angst you seem to feel so strongly about the presence, absence, history of the cosmological constant?Stop Tzar Vladimir the Condemned!

I was watching a Brian Greene interview from late 2023 or early 2024.
He covered some issues he would talk about in the multi-hour program. He said he needs to explain to people the difference between Dark Energy and the observational evidence for Dark Energy. He never got around to it. I was upset he did not. Because it has been a pretty big problem for people to understand the difference. Do you have a clue, why I feel concerned that NOT ONLY the general public does not understand the nuances, but EVEN those who understand (a little) MORE than the general public fail to understand. It is not about UNKNOWN unknowns. It is not even what the scientific community possesses in the KNOWN UNKNOWNS category. It, actually, it the non-scientific community being very very confused, that has earned my concern. (That is just the beginning of my concerns) (conCERN)

He said he needs to explain to people the difference between Dark Energy and the observational evidence for Dark Energy. He never got around to it. I was upset he did not. Because it has been a pretty big problem for people to understand the difference. That lay people do not understand the technicalities of a complex physical system does not impact the data at all. Most lay people don't understand the physics of their refrigerator. What big problem?
It, actually, it the non-scientific community being very very confused, that has earned my concern. I see. I think your concerns may be ill founded. The public doesn't care how it works as long as the beer is cold. And, frankly, as far as I can see, scientists have better things to do than track and correct all the media misunderstandings of their work. They don't think any more about the public understanding than the public thinks about understanding. If you're so emotionally injured by Brian Greene's talk you should go find someone else. The internet is blessed with a lot of good science communicators covering all the hard science in enough detail for good, if not expert, understanding. If what is available is not in depth technical enough for your wants then you are going to have to engage in concentrated self-study. I still don't see how this elicits such a strong emotional reaction. Are you naturally this high strung about (what I consider) mundane topics?Stop Tzar Vladimir the Condemned!

I like Brian Greene
His book on the Many World's Interpretation, was the one that made the case that eternal inflation was a major impetus for the possibility of the Many Worlds Interpretation being true. (Green accepts its ultimate truth) Green has been accused of being a big promotor of String Theory, when the evidence isn't quite so stellar. Eric Weinstein says Greene and Kaku are "out of control".

Ok. Good. Thank you.
