Euclid won't "find" dark matter or dark energy as things; it will map where our descriptions break down

Persistent, organized mismatches aren't noise; they're the signal.

Is the expansion of the universe slowing down? It is widely accepted that the universe is expanding at an accelerating rate, but now researchers say our measurements of the mysterious force driving that may be wrong and that the universe began to ...

If you're curious about the Son et al. (2025) #MNRAS study published by @royalastrosoc.bsky.social, @astrojonny.bsky.social has written a fascinating report in @newscientist.com - is there now a real case that #DarkEnergy must be physics beyond #LambdaCDM?

Everyone wants something better than ΛCDM There’s a nice short review article on arXiv today by Mike Turner. I wasn’t going to share it because it hasn’t got any pictures in it, but changed my mind. Here is the abstract The current cosmological paradigm, ΛCDM, is characterized (b) its expansive description of the history of the Universe, its deep connections to particle […]

Critique of Lambda-CDM: A key theme is skepticism towards the Lambda-CDM model's reliance on dark matter/energy, seen by some as overly flexible additions akin to epicycles in older models. #LambdaCDM 2/6

6/8 Despite this vast complexity, the universe's structure can be described by just six parameters in the standard Lambda-CDM model of cosmology.

ACT's five-times-higher resolution was expected to reveal deviations from this model, potentially pointing to new physics.

Dark Energy May Not Exist: Something Stranger Might Explain The Universe There might not be a mysterious 'dark' force accelerating the expansion of the Universe after all.
