With enough mass, there is enough energy from gravity to put all fermions into different states, so the collapse continues

Are you suggesting that the authors’ “bounce” would only happen if the energy was not enough to put them into different states?

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.

My theory: There's no such thing as before and after “it”. It is it.

Block Universe. The more you think about it, the more probable it seems. Why should a universe pass time like a movie, if all moments could exist simultaneously? If there is no time, and it’s just a simulation formed in our brain, there doesn’t have to be a beginning nor end.

I've read somewhere an article which posited that our 3D universe might be inside a 4D black hole. When you cross a black hole's event horizon, the radial coordinate becomes timelike, so you lose one degree of spatial freedom. Movement is still possible in the tangential directions however, so what you get is basically an N-1 dimensional universe. So maybe our 3D universe is actually matter that fell into a 4D black…

What? Wouldn't that mean an object's speed in some direction determines how time passes once it crossed over, and conversely, it would experience its old time dimension as spatial and be able to "move through (old) time" freely after crossing the event horizon?? My head hurts.

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

There is no other entity. We're nothing. An algebra of nothing. Combine nothing with nothing in various ways (like S-terms) and it gives you physics, among many other things. From the inside we see a universe, from the outside you would see nothing.

As an agnostic I agree, but none the less it is a whole, absurd joke to be here without any answers and I demand someone to answer me.

We apologize for the inconvenience.

There have been countless academics who have discussed this topic, occasionally not behind closed doors. Regardless, it’s certainly my observation as well.

Yes. Who are these people paying for jobs that don't do anything, and why are they more concerned about "keeping people busy" than their own profits?

Why do you think profits are important?

I would think that profits are important to investors, since that's why they invest in the first place. Maybe not though.

The people doing the hiring are typically not the people concerned about profits at medium and large sized companies. Sure someone has to approve the headcount numbers, but realistically this is an extremely flawed process.

Consciousness is a specific biological adaptation which is primarily focused in the management of social relationships, status, and the prolonged adolescence of children. (and their required care) There's no reason to think that consciousness is an important question in the objective sense; it just matters to people. (and rightfully so) People wondering about consciousness in the universe might be akin to dogs wonder…

What is an important question in the objective sense? Is life, or no because that just matter to life? It seems oxymoronic, "objective question", "objectively important". I don't follow GP's sort of solipsist (?) take, but would say question of whether big bang took place in a black hole is pointless compared to life/experience and how they arise.

Solipsism is the question whether it's all made up by my mind and only my mind exists.

I am not interested in that.

I am interested in the thing in which all the made up stuff appears. And the thoughts and mind appears. Even I appear in that.
