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.

- exe34 3y agoI'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.
- magicalhippo 3y agoThat 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.
