The Cosmological Principle treats our observable region as representative of the whole universe, letting cosmologists generalize local measurements to the entire cosmos and enabling models like the standard ΛCDM.

[#Cosmology] Is the Standard Cosmological Model (#ΛCDM) compatible with recent tensions concerning the #Hubble constant (linked to the #expansion of the Universe) and matter density fluctuations in the #Universe?
Yes, say the cosmologists at IRAP: after analyzing nearly 200 #alternative models, they have revisited the Standard Model: "this new version is statistically equivalent or better than previously proposed unbiased extensions".

Oui, répondent les cosmologiste de l'IRAP : après analyse de près de 200 #modèles alternatifs, ils ont revisité le modèle standard : "cette nouvelle version est statistiquement équivalente ou meilleure que les extensions précédemment proposées sans biais".

"Here, as a last-ditch effort, we point out that disregarding the large angular scale polarization obtained by Planck, which allows for significantly larger values of the matter clustering parameter σ8, could lead to better agreement between Planck and JWST within the ΛCDM framework."*Last-ditch*: a desperate final attempt = If this explanation doesn't work, they will give up #ΛCDM 👍

Rising Tension.
Early Cosmicflows-4 result: R. Watkins+co-authors present an estimate of the bulk flow, the average velocity of the survey volume: about 400 km/s. This has an epsilonesque chance of occurring in the ΛCDM model with CMB derived parameters.
