I always pondered about everything in our universe getting swallowed up continuously merging black holes until all of a sudden "everything" is "in" the black hole and then suddenly that's your big bang, and everything starts all over.

I don't have the Ph.D physics/maths skills to work out the plausibility of any of that (or variations on that) but I've always felt I've been good at coming up with ideas.

Any physicist wants to work with me, I'm https://purpleidea.com/contact/

If you agree with the above comment, doesn't that make you an atheist, not agnostic?

Atheists are people that don't bleieve there is a God. Agnostics are people who don't know they are atheists. -- Aron Ra

I can't 100% prove that I'm an atheist, so I'm definitely agnostic. The brain structure is constantly evolving and it's unclear how that exactly works. What is a "belief" any way, and what does it matter for?

> But how come Penrose’s theorems forbid out such outcomes? It’s all down to a rule called the quantum exclusion principle, which states that no two identical particles known as fermions can occupy the same quantum state (such as angular momentum, or “spin”).

> And we show that this rule prevents the particles in the collapsing matter from being squeezed indefinitely. As a result, the collapse halts and reverses. The bounce is not only possible – it’s inevitable under the right conditions.

Do I understand right, that this would mean that every formation of a black hole would result in a bounce?

I've heard about interesting theory. Since we observe large early galaxies, to explain them scientists postulate that they must have grown very quickly. But recently some scientists calculated how much light would such quickly growing galaxies could have emitted. And it turned out that this light after being dispersed by the dust and redshifted by the expansion of the universe it should have contribute to CMB, up to 100% of it's observed intensity. What's interesting they didn't make any assumptions outside of established modern cosmology. Just So it's entirely possible that CMB is something completely different than what we believed.

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

> the percent of people who consider their jobs meaningless

Worth to point out that there is a huge difference between people considering their jobs meaningless AND their job being meaningless, though.

I think you're right, but it's not how I remember it for some reason. I didn't read the book "Bullshit Jobs" [1] as an attempt to quantify how many jobs were bullshit. The author was an anthropologist with no interest in quantifying the economic impact. It's lots of amusing anecdotes from frustrated workers and a nudge for people to question the efficiency of capitalism. At least that's how I read it. But reading the…

> while he claims that 50% of jobs are useless, less than 20% of workers feel that way, and those who feel their jobs are useless do not correlate with whether their job is useless. (Garbage collectors, janitors, and other essential workers more often felt like their jobs were useless than people in jobs classified by Graeber as useless.)

Well, again, there is a huge difference between one's own perception of their job being useful or not. I believe garbage collectors, janitors, and nurses, are not examples of useless jobs. Useless jobs are mainly in the office, called "paper pushers". I mean come on, have you not been to any jobs (nor heard of any) where you had to pretend you were busy just to get paid? I saw plenty of cases.

Why do you think God will have a name? Name is used by humans to identity a person among a lot of other persons. Why will God have a name if it is the only thing in existence? To answer the question of why humans give name to God. It's to make god more relatable so that they can workshop it. And use devotion to come closer with it. Look up Bhakti Yoga.

How about just having one God vs many? If there is a single omnipotent being, why do various cultures have multiple gods? And why do different cultures’ gods tell them different things?

Fair question. So my understanding is God is consciousness. It's omnipotent, all knowing and eternal. It's the only thing which is constant in your life and it sees everything you do.

Now, you cannot worship consciousness as humans because it's invisible and you can never imagine it. You need a version of consciousness that you can see as well as you can relate to. So cultures invent localized version of God which people can relate to. And of course it will have attributes similar to that of the culture. But the properties kind of still hold. Like all knowing, powerful etc.

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…

> What the paper actually proposes [...] (Emphasis mine) I haven't read the paper yet, but this sounds like a (good) summary of exactly what the article is saying. It makes me wonder what, if anything, you feel is different from the way you put it and the way it is explained in the article? As a layman they seem the same to me.

The article was written by the main author of the paper, so yes, it's a good summary :)

The big bang sounds like how a computer would interpret being turned on. Anyone else think this is what happened?

Computers refer to this as 'the Big Boot'.

One day someone's going to reboot that computer and I'm going to lose all my carefully curated trauma.

> The center of a black hole is infinitely dense. That's why it even exists. The event horizon is not the black hole. Arguing semantics is rather boring when it's obvious you understood the point he was trying to make. > Our universe is expanding. It's density is not fixed. None of that precludes uniform density at large scales.

>> Our universe is expanding. It's density is not fixed. > None of that precludes uniform density at large scales. According to observation, the universe is expanding. An argument that it's really static at a large scale would require contradicting observational evidence, but none exists. A theory that requires abandoning observational evidence bears a special burden, which this theory lacks.

Black holes are capable of expanding, they do it by eating material from outside.
