Can you cite your sources please?

Sabine Hossenfelder has a few comments on this topic in her YT channel.

Sabine Hossenfelder cast herself out from academia and took a recent turn to monetizing laundering peoples vague understanding string theory is a waste of time (cannot be proven empirically) into academia is doing fake work and if they'd apologize and own up to it, maybe we would trust them again.

Most famously, through a bizarrely written letter from an anonymous whistleblower pleading that she not topple the academy, as it would ruin the lives of thousands of academics making up things to get grant money to survive.

I think a point they are trying to make is that the border of a black hole is only to us outside observers, if you yourself fell into one you wouldn't notice anything specific when you crossed the boundary. The popular example of hawking radiation references a border and pairs of particles, however its actually only to help people understand the idea of what is going on

> if you yourself fell into one you wouldn't notice anything specific when you crossed the boundary. Wouldn't you notice that fairly suddenly everything's getting brighter because all the light/radiation is sucked back in?

I learned recently on [a video](https://youtu.be/a4vHwY0wMjs?t=246) that for very large black holes , we suspect there is no difference.

For smaller BH, the gravity gradient is higher and it would be detectable.

That exemplifies a much deeper problem than good information, “Good Law”: https://en.m.wikipedia.org/wiki/Good_law As an aside, the earth is almost flat, just not nearly as flat as the Universe.

It’s in the Library of Babylon. My standing citation.

Not many people these days like to hear this (I myself was one of them), but the answer to this is in Genesis. There's a reason some of the most famous mathematicians, scientists, engineers, and philosophers of all time believe(d) in God. The Hebrew name of God, YHWH, literally means "He Who Is." In other words, the Self-Existent One. The father and originator of all things that were, are, and will be, who exists out…

"An equation means nothing to me unless it expresses a thought of God." — Ramanujan

I like to think he was referring to computation. There's a reality to the constant pi, its computation, and ourselves and the representation being part of that same universe.

Predicting inflation rates may be harder than discovering the birth of the universe actually, because it would require perfect knowledge of the present and by the time you compute it it's out of date.

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.

Might as well believe in God if you’re going to believe in spontaneous accidental creation…

I don't think so - god is substantially less parsimonious. But in the end, I think you're sort of using two different notions of belief as if they were the same. I believe (lowercase b) in all sorts of stuff, scientific and otherwise, but believing in God typically indicates some kind of act of faith, which is to say, ultimately, to believe in something despite the absence of evidence for it and for some deeper reaso…

Historically, in the West at least, the ability or inability to reason one's way to the existence of God determined whether you needed to rely on faith or not.

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's in a 1D black hole?

/dev/null I presume

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 a 13.8 billion year expansion. That is general relativity applied across frames.

Simply put this is a relativistic collapse model with quantum corrections that avoids singularities and produces testable predictions, including small negative curvature and a natural inflation-like phase.
