I thought the cosmological expansion theory of the standard model was falling apart calling into question the Big Bang theory. If that’s the case, then are we sure we have a good handle on the age of the universe?

Do you have any links where I can read more about that? That's fascinating and I wasn't aware, and I evidently am not using the right search terms to find out more

Maybe unrelated but YouTube has been throwing a lot of faux science and astronomy at me lately. Youtubers reading controversial papers presented as indisputable even when there's no scientific consensus at all on the results.

It's depressing to think about, but for many intents and purposes fake space facts are just as good as true space facts.

Especially for purposes of monetizing YouTube videos.

I believe they’re referring to the “crisis in cosmology”. I’m purely a layman, but I found some videos useful. I believe at least PBS Space-Time [1] is well regarded in physics circles (for laymen explanations.). I found the other one [2] to be more digestible though.

Depends on your perspective I suppose. Most of the stars have already formed and star formation will slowly grind to a halt in a few billion years.

old and young universe then :)

At least, I can understand visualize the time scale of the universe a lot better than I can visual the length scale. Speed of light doesn't feel like 1/1 to humans!
