can the metallicity...f these stars
Doubtful. They don'y even have a real redshift - just photometry.

The code authors claim it is goof to Z=4,
OK, this is definitely one of your typos you should definitely fix. :oldbiggrin:

Now Sabine is mononymic like Cher, Madonna and Prince?
And Lubos. You forgot Lubos. (Otoh, I wish I could.)

Sabine has said that dark matter predictions are not matching up to observations but MOND is.
Stacy McGaugh's blog Triton Station is probably a better source for what's going on with actual data vs theories. He has just now (10-Mar-2023) put out a new post about this. One of the things he reminds is that this business about "big galaxies early" was a prediction of MOND. See his post from 3-Jan-2022.

More of a Freudian slip. Photometric redfshifts are little better tnan "Golly, it sure looks red". Yes, someimes that's all you have, but it's hard to get excited until the real data - i.e. spectroscopic redshifts - come in.

No matter what Beyonce and JayZ post on their blogs.

Agreed. The papers will be published and bloggers and YouTubers will comment including The Hoss and others but ultimately, it will be discussion on PF that will make sense of it all. To me at least.
