Re: Webb and Hubble confirm Universe's expansion rate
#2This sort of brushes on it but for a long time there was hope at resolving the Hubble Tension by saying that Hubble telescope’s measurements were incorrect, because that would be the most simple explanation. This was not the case, so if anything, the mystery deepens. I don’t know for certain but I believe Hubble’s estimation has been widely accepted for a while though, because we’ve been using the 13.8 billion cosmological age estimate ever since I started brushing up my layman's understanding of the subject.

Basically it means that we can't regard the Hubble result as a mismeasurement and the age of the universe seems to be different depending on how you measure it.
From the article:
"The bottom line is that the so-called Hubble Tension between what happens in the nearby Universe compared to the early Universe’s expansion remains a nagging puzzle for cosmologists. There may be something woven into the fabric of space that we don’t yet understand."

Either we live in an unusually under dense region of the universe or our models are wrong ("new physics").

#9Unbelievable how much we can work out from just the odd photon hitting us from somewhere in the great unknown.
