It's for the folks plagued by existential dread that need to know where we came from. Well son, it's black holes the whole way down.

I mean, what if you happen to live trillions of years and reach the edge of the universe?

I mean technically the sentence structure says that:

• Fact: NASA has done something
• That something: potentially discovering that we are in a black hole

So in a sense there is no contradiction there with the words "fact" and "potentially". Although there is a relevant possibility for confusion of what is being stated as a fact, so your point stands. I just like nitpicking on technicalities :D

Isn't matter the whole issue

And then punch your landlord in the face. They are a landlord, they probably deserve it.

It's been a while so I'm a little hazy on the details, but in one of the Culture books by Iain M. Banks there's a part where a bunch of Minds (for those unfamiliar: kind of beyond godlike artificial intelligences that run a utopian civilization, the eponymous Culture) are talking about how they can create simulations within simulations so perfect that it would be impossible to tell if you were in one, and what if their entire reality was just one in a long chain of nested, perfect simulations? But in the end they come to the conclusion that there's no way to tell and nothing they can do about it anyway, so they might as well just get on with it lol.

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

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.

I, for one, would like to see the cafeteria menus in advance so parents can adjust their dinner menus accordingly. I don't like the idea of Milhouse having two spaghettification meals in one day.

time to spagettify spaghettis, lets create hyperspag

Your life just got worse. You're paying rent inside of a black hole.
