"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 👍

"In his presentation, Prof. Scolnic demonstrated how even tweaking over a dozen aspects of their analysis couldn’t get below about 72.5 km/s/Mpc"

@fraser What is the difference between this 'new theory' and suggesting that angels pushed the universe to give it more expansion speed just before recombination?

From a #PhilosophyOfScience point of view, a 'phase change' can't be confirmed independently of the #HubbleTension it is trying to resolve. A poor reflection on cosmologists.

"the popular claim that 'dark matter explains many independent observations' is misleading"
"... cosmology today is an evolving, unstable field of research. It’s not unlikely to have a completely different model in five, ten or twenty years."

Is Something Missing from the #Standard #Model of the #Universe? - A 2018 #HubbleSpaceTelescope finding confirmed a nagging #discrepancy about the #HubbleConstant showing the universe is expanding faster now than was shortly after the #bigbang. #Researchers hinted that there may be #newphysics to explain the inconsistency known as the ‘#HubbleTension’.
