I have read several articles like this one.
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?

Go in chronological order if you want the full picture, but it’s not really necessary.
I’d describe it as a faux-crisis. It’s not like astronomy as a field is going to end if we don’t get it sorted by next week. It is annoying though.
