    Here's a summary

    It's by no means confirmed. It's one theory out of many. The JWST data shows galaxies have a significant preference to all spin the same way. Mathematicians say this would be evidence in favor but not fully confirm the black hole theory (also called the Swarthschild theory if you want to DDG more). Some suspect it's bias from the rotation of our own galaxy affecting the data and they plan to calibrate more

    Do you have an essay you could throw at me, or some kind of video that explains it in reasonably understandable detail?

    I follow PBS Spacetime already, so chances are I've seen the videos you're thinking of and can't remember them offhand. I'll give your link a read tho, thanks!

    Anton Petrov also has good analysis of papers like that, here's him explaining why no the observation does not support the black hole cosmology as long as we're not cherrypicking https://youtu.be/xXSV9JaWxCE

    Doesn't mean the paper is shit, it always helps drawing parallels to notice differences and refine our equations, but the sensationalism must prevail for all the news sites reporting on it I guess.

    I wonder if there are rules pertaining to black holes existing within other black holes. If black hole A is inside black hole B, does it make sense to have a meaningful distinction between black hole A and the other stuff inside black hole B?

    It's not a thing. Or, like, this theory ("black hole cosmology") has been around for ages, it's not broadly accepted and I can find no evidence of NASA publishing anything explicitly in support of it. The pop-sci articles are all linking back to this study which decidedly does not make the conclusion the universe might be inside a black hole.
