The article introduces a dynamic cosmological constant in the current ΛCDM cosmological model to account for some data from the James Webb telescope. The new model would have the age of the universe at ~27 billion years.
This is interesting. Unfortunately some popular science magazines are already presenting it as a fact…
That’s really interesting! I read the abstract but I don’t really follow exactly what it is they’re proposing (and I don’t really expect I would follow even if I tried to work my way through the actual paper). It’ll be interesting to see whether other astronomers and astrophysicists take up this new model or not in the coming years though!
This article gives a slightly more understandable and not too sensationalistic summary: https://phys.org/news/2023-07-age-universe-billion-years-previously.html
