I have read several articles like this one.

https://www.livescience.com/space/cosmology/james-webb-telescope-confirms-there-is-something-seriously-wrong-with-our-understanding-of-the-universe

They all seem to be saying that there is a “crisis in cosmology”, where different measurements can’t reconcile what the value of the hubble constant is.

Then I watched this video last night that seems to be saying it’s all just tweaking different models.

I’m not entirely sure if they’re talking about two slightly different things. (Hubble’s constant, and the predicted age of the universe.) Or if the “crisis” is really just a misunderstanding, or just clickbait tactics. Any informed opinions on the subject?

    OK, I’ve actually watched the video this time (the last part, as you suggested). It seems that the author decided to leave out the debate about the Hubble constant and talk about other phenomena in the early universe, which also have their uncertainties.

    As far as I can tell, the Hubble tension is still a thing, and JWST only confirmed the measurements of the Hubble telescope. See for example this recent article on ars technica.
