Things nearest the center would move towards the center at an accelerated rate. So observation from the perspective of an object falling in the black hole could be everything is expanding? Since everything is getting compressed as it goes toward the center. I’m not an expert on anything but it seems like an intriguing concept.
we learn that the entire observable universe – the area that sits within the “Hubble radius” is also on that line. In other words, if a black hole was as large as the universe we can see, it would have the same density as the universe.
Not saying any of this makes sense, but you seem to be working with different assumptions.
Another narrative could be: As mass gets added to the black hole, it (the universe) grows.
Doesn’t that not mesh with the whole “space is constantly expanding” thing?
If the observable universe was all in a black hole, everything would be moving closer together as we get pulled toward the singularity.
…right? Definitely not my area of expertise, but the little I do know is raising a few flags.

Iflscience is a pop science website. There’s no guarantee this isn’t bullshit.
You can just read the submission in the AJP issue: https://pubs.aip.org/aapt/ajp/article/91/10/819/2911822/All-objects-and-some-questions

There’s also an event horizon where space is expanding away from us rapidly enough that we can never get that far no matter how long we travel.
