Full paper here[1], and here's[2] the earlier paper about the model itself. They overloaded the CCC acronym, which has also been used for Penrose's Conformal cyclic cosmology[3], though can't say which is more speculative. I'm also reminded of Von Neumann's elephant[4], given that they vary the constants it doesn't seem that surprising I suppose that they can get a fit. Freeman Dyson learned this the hard way[5]. This is just one test, the article mentions a few others that they'll need to pass to be a serious contender. Will be interesting to see how it goes.

  I'd say cyclic universe is way more kooky - it's wishful thinking that doesn't match the observations. https://bigthink.com/starts-with-a-bang/no-universe-before-big-bang/ https://bigthink.com/starts-with-a-bang/no-universe-before-b... This one is trying to replace one of the invisible mass with a modified physics.

    That was my intuition, but I'm just a layman so... that said, both seem to be geared towards making testable predictions, which makes them both a lot better than some other proposed alternatives.

“Dark matter” always seemed like a cop out to this layperson. You can’t just give up and attribute problems with your theory to a mysterious substance that can’t be seen or measured!

  You mean like Planet Nine? If Dark Matter exists it can be measured by it's effects on its surroundings

  As another layperson with a background in finance, it always felt like the cosmological equivalent of making a Balance Sheet balance by plugging the difference in a model

    Well not at all. If anything, that's the MOND theories. The proper almost exact analogue to dark matter is an accountant noticing something's wrong with the figures, trying to find an honest mistake somewhere, and failing to do so, starting to reasonably suspect that there's embezzlement going on and the missing money has not simply disappeared into the ether.

      Except accounting is just fun with numbers, so by definition you know if something is off, whereas with cosmological models you can't ever know if the math is missing something or if the model itself is inaccurate I'm saying (as others seem to also be saying) that it feels akin to saying "trust me, the model is right, we just haven't been able to find the missing $1 million but I'm sure it exists somewhere" It's not a particularly innovative or insightful criticism of current models, but that's what it feels like from the outside looking in. Chalk it up to ignorance, if you'd like, but I still feel like asking "are you sure you can't fix the model instead of plugging it with some unobservable feature?"

It’s too bad the piece doesn’t have any reactions from other physicists. Is this a pretty speculative idea in the field or closer to the mainstream?
- exe34 3y ago
  It's completely on the fringe side - doesn't mean it's wrong, just that it will need to explain a whole lot of known observations and then predict something that we can't currently explain before it catches on.

Just another way of writing the equations. Not any kind of discovery. Write the other headline, equally as 'provable': Tired light does not exist, it's really dark matter.

Scientists are grasping at straws to explain the JWST observations but I still prefer Randall Mills' classical theory now thirty years old, that has stood up well with all its predictions coming true despite the howls of laughter from the skeptics. The model of atomic structure is superior and it shows dark matter is just hydrogen in a lower-energy non-radiative state. https://brilliantlightpower.com/theory/ https://brilliantlightpower.com/theory/

  Many physicists have dismissed BLP’s theories as incompatible with established principles of physics. The concept of hydrinos, for example, contradicts the known laws of quantum mechanics, which are well-supported by experimental evidence. Critics argue that BLP’s approach contains mathematical errors and unjustified assumptions. There have also been allegations of portions of Mills’ work being copied from other texts without proper attribution. Despite BLP’s claims of breakthroughs and imminent commercialization, the company has faced significant challenges in gaining acceptance from the scientific community and in securing patents. The theory has not been independently verified, and there is widespread doubt about the viability of the technology proposed by BLP

    Please don't post unattributed copied and pasted LLM outputs here. That's not what I come to HN to read

      The training data comes from here https://en.wikipedia.org/wiki/Talk:Brilliant_Light_Power/Archive_1 https://en.wikipedia.org/wiki/Talk:Brilliant_Light_Power/Arc... 20 years worth of Wikipedia gate keeping. On the up side one can read how the sausage is made. For negative statements the uneducated troll Eric Krieg is a suitable source. For positive statements no peer journal is good enough. 2005 > Dr. Mills was awarded a Bachelor of Arts Degree in Chemistry, summa cum laude in 1982, and a Doctor of Medicine Degree from Harvard Medical School in 1986. Why are you guys so reticent to accept the degrees of genuine researchers, 2016 > Trends Journal : after completing his medical studies in three years, Mills spent a fourth year at MIT investigating electrical engineering. > > Where did The Trends Journal (TTJ) get Mills' MIT background? 2024, Mills still doesn't have any professional training (according to wikipedia) The LLM's must be full of this garbage.

Explain like I'm five here, was JWST supposed to be able to see further back than Hubble to the origins of the universe? Has this happened? What are the findings?
