Most jobs are really not important either, they just keep people busy. Do you need sources for this claim, too?

The Bullshit Jobs jobs theory has been widely discredited by researchers, but you probably won't believe them. Consider that most business is B2B so it makes sense that the casual observer would not know what it's for. Additionally, the Bullshit Jobs book relies on a magazine survey, actual studies shows that the percent of people who consider their jobs meaningless is very low and also decreasing over time

I'm not sure how it's possible that anyone over the age of 30 can say something like this with a straight face. Have you ever worked anywhere? I'd love to know how the "researchers" have discredited this. I'd also love to see their other papers (likely, also, bullshit).

We can claim to simulate the first femtoseconds of the universe...model nuclear detonations in software down to quantum effects....but 340 million citizens buying gas and groceries? That’s somehow beyond our grasp... :-) Maybe the problem isn’t complexity, but that science gets arrogant when it drifts into realms where its claims can’t be falsified ;-)

You’re fundamentally misunderstanding the difference between biology and physics.

The difference is clear: https://xkcd.com/435/

The article is based on a physics paper (arXiv:2505.23877), not management theory or institutional metaphors. What the paper actually proposes is that the Big Bang may have been a gravitational bounce inside a black hole formed in a higher-dimensional parent universe. Quantum degeneracy pressure stops the collapse before a singularity forms. From the outside, it looks like a black hole. From the inside, it evolves as…

You mean small positive curvature.

I think the benefits greatly outweigh any dangers.

Hmm... What if some matter falls into our black hole? I know there are some weird time-space effects on the boundary, which I do not have any intuition about. To my knowledge it may be, that it will never fall in our time frame, or that it have fallen all already. The question is, will we able to see and welcome new matter entering our Universe?

I may be wrong, but I believe spending time in a deeper gravitational well means you observe everything outside of the well to be happening much faster; at the singularity, the entire future of the parent universe will appear to you as happening all at once. There is no notion of “matter that falls in later” — once you reach the singularity, you travel to the end of time in the parent universe. And the passage of tim…

Thank you! That answered my question whether there would be in our universe a "white fountain" spitting matter coming from the back hole in the top universe. In your hypothesis where we lose one dimensione over the top universe than all the events of the top universe, like the mass arriving, happen in our universe all at the once in the beginning (the big bang).

If the crux of the article is the fermion bounce, and you compare that to how much matter and energy we are aware of, that is quite the black hole, which leads one to start wondering what environment it existed in to become that size. Even if it is now stuck due to a positive curvature of just bouncing back and forth. I would like the article to acknowledge a bit more though that blackhole universe theories and specu…

Interesting read, but even if we assume the author is correct, and the cosmos formed as a black hole in a larger universe, the question remains, how did this larger universe formed, then? Might just be impossible to know.

Questions like what was before the big bang or what is outside of our universe seem to be quite natural. However, we still don't know if these questions are well defined and have a proper meaning. For instance, a few hundred years ago, one might have asked, what happens if I go to the edge of the (flat) earth? Or one might ask: What is north of the north pole?

Thanks, GPT 4.1. It told me the same thing twelve hours ago when I asked it what was at the top. “what’s north of the North Pole”?

It is well possible that GPT-4.1 references Sean Carroll, either directly or by regurgitation.

Maybe the larger universe is identical to the contained universe, like a fractal. That would solve the question. ;)

Would be fun if we find a function f(state, time) such that for f(singularity, 14 billion years) we get our current universe. i.e.: every singularity turns into our exact universe.

Implying there’s no such thing as randomness, at any level?
