black hole problem

While black holes and the Big Bang are closely linked, it's possible that something other than a black hole could be something far more powerful. Currently, the most powerful black hole is the one that truly exists. Historically, if a black hole has ever exploded, it could potentially create more than one universe. However, according to the theory of black holes, they absorb all matter and light. Does this mean that at that moment, the black hole didn't explode but was absorbed and disappeared? Scientists also speak of wormholes, which are spacetime tunnels connected to black holes. Could it be that the matter from the black hole's explosion was sucked in, eventually ending up in another "universe".Because black holes are constantly collapsing, just like when we walk into quicksand we sink, this is the same phenomenon.

What if black holes are Bulk parasites, and our Universe is just a 3D quarantine trap to destroy them?

Hey Reddit!

I’m not a professional physicist, just a guy with a solid analytical mind. While recovering from a brutal 1-liter-of-whiskey hangover, my brain connected M-theory, black holes, and thermodynamics into a dark, crazy model. No ethical BS, just pure logic. I call it the Anti-Parasitic Localization Model.

Here is the no-nonsense breakdown of why our world is a cosmic mousetrap, why TON 618 is a giant tick, and why your consciousness is just the wind behind a speeding car.

  1. Time Doesn't Exist (Sorry, Einstein)

First, let's drop the sci-fi cliché about time being the "fourth dimension". Time is a total illusion. It’s just a way to measure the movement of matter.

No stuff moving around = no changes = no time.

If you look at pure geometry, reality looks like this:

  • The Bulk: A massive, eternal 10-dimensional spatial ocean (10D) packed with pure energy. Time doesn't exist there; everything just is.
  • Our Universe: A tiny, broken 3D glitch, a literal spatial "scar" on the body of the Bulk.

When a part of the Bulk glitches and 7 of its dimensions collapse into a microscopic knot, a ton of energy gets trapped in a tight 3D cage. Boom — Big Bang. The trapped energy starts violently bouncing off the walls, trying to expand the cage. We look at this chaotic atomic traffic and call it "the flow of time."

  1. TON 618 is a Massive Cosmic Tick

The crazy energy density of the 10D Bulk naturally breeds gravitational monsters. Here is the real hierarchy of reality:

The Bulk (10D) → Black Holes (The Apex Predators) → Scar-Universes (3D Glitches)

Black holes are not 3D spheres. They are full 10-dimensional beasts. In the Bulk, a black hole is a massive parasite. Floating in an endless ocean of energy, it just sits there and eats forever. It can’t die or evaporate because the food supply from the Bulk is infinite. They are like cancer tumors of the hyperspace.

The monster TON 618 is a native citizen of the Bulk. It got fat on Bulk energy long before our Universe even sparked.

When a parasite gets too big, the Bulk triggers an immune response. The 10D space cracks and wraps a 3D scar-cocoon (our Universe) right around the monster. The mouse trap snaps shut. For us, TON 618 looks like a terrifying sphere, but in reality, it’s a 10D drain pipe piercing our world on its way to the Bulk. Our Universe is a quarantine zone meant to cut the parasite off from the Bulk’s infinite power grid.

  1. The Death of the Cosmic Matryoshka

Once trapped in our 3D cage, TON 618 keeps eating our stars, gas, and galaxies. The density inside its singularity becomes so extreme that it turns inside out, triggering a new Big Bang and birthing a daughter universe inside it. But if you think this "Matryoshka doll" goes on forever, you are wrong. Thermodynamics is a harsh b*tch:

  1. Stellar Black Holes are Useless: Small black holes born from dying stars are too poor. They don't have the Bulk's energy. They can't birth new worlds; they will just evaporate via Hawking radiation

  2. Energy Deprivation: Because TON 618 is locked in our 3D cage, it can't plug into the Bulk's battery anymore. The energy inside it is limited. The daughter universe inside it gets a pathetic budget. It won't have enough energy to spawn another monster like TON 618.

  3. Game Over: The daughter world quickly dies out. TON 618 wastes all its fuel on this single final cycle and completely evaporates, spitting its mass back into the Bulk via gravitons.

  4. How the Drain Pipe Works

In our 3D scar, gravity behaves weirdly because it’s constantly pulled by the 10D space outside. According to modified Einstein equations on a brane, our 3D space experiences permanent geometric tension from the Bulk's Weyl tensor projection. It’s like a physical pressure from the outside world.

The total mass-energy balance of our isolated cage depends on three things: the initial Big Bang energy, the massive energy drain through TON 618, and the slow Hawking evaporation of smaller black holes.

Since the daughter universe inside TON 618 cannot breed new high-order parasites, the cycle ends. As time goes to infinity, all matter inside the scar breaks down and leaves the Universe via gravitons. The 3D scar completely clears out all trapped mass, flattens out, and heals, becoming a clean part of the 10D Bulk again.

  1. Consciousness is Just the Wind Behind a Car

In this cold architecture, what the hell is human consciousness? It's not a soul. It's just a byproduct of the trap — a quantum noise.

Think of a speeding car. Its goal is to move from point A to point B. But it moves so fast that it inevitably stirs up the air, creating wind. The car didn't "try" to make wind; it just happened.

Our atoms are jammed in a tight 3D cage and forced to move at insane speeds just to keep our biological bodies alive. This heavy atomic traffic creates an information vortex. This "quantum wind" is what we feel as our "Inner Self." We are just a passive screen watching a movie projected by moving matter.

When the drain pipes (black holes) finish siphoning all matter back to the Bulk, the movement stops. The car parks — and the quantum wind of consciousness goes silent forever. The Bulk wins, and perfect order is restored

Black hole detection

Hypothesis: The Quicksand-Gateway Model of Black Holes ​1. Abstract ​This proposal introduces the "Quicksand-Gateway" model of black holes, challenging the traditional view of black holes as mere gravitational dead-ends. It proposes that black holes function as vital conduits in a multiversal recycling system, connecting the collapse of matter in one universe to the creation of another via white hole eruptions. ​2. The "Quicksand" Mechanism ​Instead of perceiving black holes as passive "vacuum cleaners," we define them as dynamic spacetime sinks. ​The Quicksand Effect: As matter approaches a black hole, spacetime itself behaves like fluid quicksand. Matter is not "sucked" in; it is carried by the irreversible, inward flow of spacetime towards a singularity. ​The Event Horizon: This boundary represents the "point of no return" where the inward velocity of spacetime exceeds the speed of light, rendering escape impossible. ​3. Information Transfer and Multiversal Cycling ​Black holes serve as cosmic logistics hubs: ​The Conduit: Matter and energy are compressed and funneled through a wormhole (a spacetime tunnel). ​The Exit: What we observe as a "Big Bang" in a new universe is the material exit point—a White Hole. ​Cyclic Continuity: This creates an eternal loop where the death of a parent universe fuels the birth of a child universe. ​4. Implications for Biological Evolution ​Genetic Blueprints: Biological information may act as resilient carriers through these transitions. ​Convergent Evolution: Due to varying physical parameters across universes, life forms adapt to their local environment. Thus, "aliens" may be divergent evolutionary versions of the same original "human" blueprint, reshaped by different environmental pressures. ​5. Disclaimer ​This hypothesis regarding black holes as "spacetime quicksand" and "multiversal gateways" is based on personal observation and logical deduction. I acknowledge that these ideas currently lack rigorous mathematical proof or observational data, and serve as a speculative experiment. I look forward to engaging with the scientific community to test the validity of these ideas and to further my understanding of the universe.

Question about gravitational lensing and spacetime grid visualizations

I’ve been trying to understand how spacetime deformation should actually look around a massive object.
The first image is the standard gravitational lensing picture: light rays passing near a massive object bend around it.
The second image is my attempt to describe anisotropic deformation geometrically (using polygons becoming rounded under compression).
The third image is a common visualization of a distorted grid around a mass.
My question is about the third image.
If light follows geodesics, and those geodesics bend around the mass as shown in the first image, shouldn’t a square built from those local directions become progressively rounded (similar to the second image), rather than deform into the pinched “hourglass” shape shown in the blue grid?
I’m not claiming General Relativity is wrong. GR tells us that the metric changes, and gravitational lensing clearly confirms that. I’m only asking whether the popular blue grid visualization is actually a faithful representation of the local geometry, or whether it’s just an artistic illustration.
In other words:
Is the blue grid mathematically derived from the spacetime metric?
Or is it simply a visualization intended to communicate curvature qualitatively?
If it is mathematically correct, could someone explain why the local deformation has that particular shape?
I’d really appreciate an explanation from people familiar with differential geometry or GR.

M87* Black hole. First ever image along with the magnetic field

Well this is not a like a photo taken from a telescope direct. But by collecting the raw data, radio waves from the accretion disk around the black hole, they were able to reconstruct the raw data into a image!

Those lines depicts the strength of magnetic field created by the plasma, the temperature might reach up to tens of billions of Kelvin.

Remember that this was not collected from a single telescope. They used global network of radio telescopes in our world targeting this M87* black hole stitching all the raw data into a reconstructed visual image

The Black Hole Information Paradox is breaking my brain. How do physicists actually look at this?

Hey everyone,I’ve been reading up on the Black Hole Information Paradox recently, and the more I think about it, the more it honestly melts my brain.On one hand, quantum mechanics says information can never be destroyed. On the other hand, Hawking radiation suggests that black holes eventually evaporate completely, leaving behind just random thermal radiation with no trace of whatever fell inside.To me, this feels like an absolute dead end for modern physics. If information is lost, quantum mechanics is broken. If information isn't lost, relativity or causality has a massive issue. It feels like our two best descriptions of reality are just staring at each other, refusing to compromise.I know there are ideas out there like the holographic principle, fuzzballs, or even the firewall paradox, but they all sound so extreme.I’m curious about where the physics community stands on this right now. Which solution do you personally find the most compelling, or do you think we are completely missing a fundamental piece of the puzzle here?Would love to hear some thoughts and different perspectives on this. Thanks!

Could black holes be a new type of celestial object rather than actual holes?

What if black holes are not actually holes?

I’ve been thinking about an alternative interpretation of black holes.

This is not an attempt to disprove modern physics. It is simply a speculative thought experiment.

Starting point

Current astrophysics suggests that very massive stars can collapse and form black holes after the end of their life cycle.

If that is true, then a black hole originates from an object that already possessed enormous mass.

That led me to ask a simple question.

If all of that mass still exists, what exactly is at the center?

My interpretation

Rather than imagining an empty hole, I wonder if the center is actually an extremely dense spherical object.

Everything a black hole absorbs—stars, planets, gas, plasma, dust, heavy elements—could become part of this object.

Instead of disappearing, matter may simply become compressed into an entirely new state.

Unlike ordinary stars, it may no longer rely on nuclear fusion.

It could represent a completely different category of celestial object, one held together only by gravity.

Event horizon

The event horizon would not be the surface of the object itself.

Instead, it would simply mark the boundary where gravity becomes too strong for light to escape.

The black shadow would therefore not be the object itself, but the visible effect of light being trapped.

Black hole mergers

If two black holes collide, perhaps two ultra-dense objects merge together.

Any material produced during the collision might exist briefly as plasma or extremely energetic matter before being pulled back by gravity into a single larger object.

Why I question the word “hole”

The name “black hole” naturally makes us imagine an empty hole.

However, we have never directly observed the interior beyond the event horizon.

For that reason, I wonder whether “hole” is simply our interpretation rather than a confirmed description of what actually exists.

I’m not claiming this is true.

I’m simply asking whether black holes could be interpreted from a different perspective.

What is the biggest physical flaw in this way of thinking?

Is there any serious theoretical connection between black hole physics and dark energy, or are they completely unrelated in modern cosmology?

I’ve been reading a bit about black holes and cosmology, and I keep wondering if there is any serious theoretical connection between black hole physics and dark energy.

From what I understand, black holes strongly affect spacetime locally, while dark energy seems to affect the large-scale expansion of the universe. But I’m curious if there are any models or hypotheses that try to link the two in a meaningful way, or if modern physics treats them as completely separate phenomena.

Is there any research direction that explores this connection, or is it generally considered unrelated in current cosmology?

I’d appreciate any explanations or corrections if I’m misunderstanding something.

Do we really live inside a black hole?

I am a member of the public (software developer) who loves physics nonetheless and recently heard about the holographic principle, the 3d bulk and the 2d boundary.

So from what I understand the 3d bulk expands because the 2d boundary is crammed with more information and that basically could be explained if our 2d boundary was that of a black hole consuming matter. Thanks to Gemini I also heard about a coincidence discovered in 1971 by an Indian theoretical physicist Raj Pathria who found that the mass of the universe could be calculated given its radius from black hole equations.

So that seems pretty much solid evidence that we live inside a black hole.

What's the counter argument? Why don't we see this as a settled proven theory?

Also, why we don't teach these things, especially the holographic principle in schools yet?

The James Webb “Little Red Dots” and the Black Hole Star

I’m not sure if there has been too much discussion about it but as someone who has been following the saga of the “little red dots”, the extremely bright and extremely distant objects discovered by the JWST, there have been some interesting developments in early universe cosmology

At first, these red objects were thought to be very early galaxies shrouded in dust, and this caused some issues because the models of galaxy formation didn’t account for them being this large this early

But thankfully, we caught a glimpse of a specific red dot that was sitting directly behind a massive galactic supercluster. This created a lensing effect that amplified the object and allowed us to perform spectrographic analysis revealing that it is most likely a massive cloud of gas surrounding an early supermassive black hole

In a similar manner to the way fusion pressure can hold up a star, a black hole could theoretically hold up a glowing gas envelope that is 67 AU across. This kind of object would be so bright it would outshine a galaxy and have a habitable zone 2 light months away. You’d have other problems to deal with like the insane radiation and 1-7 million year lifespan though. This also potentially solves the problem of where the supermassives came from.

What are other people’s thoughts on the little red dots? Thought it would be interesting having a discussion about it because it seems like kind of a big deal in black hole physics

Do Black Holes actually emit the beams of light/particles via their quasars?

Google failed me once more, and Askscience didnt approve it, so I come to you for answers.

As far as I know, once something crosses a black holes event horizon, it can not emerge again unless it becomes Hawkin Radiation (still unsure what that is as well, but thats another topic). In that regard, it doesnt matter what enters the black hole, physical matter or light, nothing gets out.

But many of the larger black holes emit quasars (I think thats the term), and from what I can tell these do have their origin in the black hole, so there is light (and possibly matter in the form of plasma?) being emitted from inside the black holes.

My question now is: How is it possible that this matter moves out of the black hole, if (as far as I know) nothing can get out? Of course there will be some part of the physics behind black holes that I am missing or misunderstand, Im just curious what that part is.

Does a BH have internal pressure?

Does a BH have internal pressure? And if yes, is it possible for the pressure and gravity to arrive at a static equilibrium for some time? Perhaps even for a long time?

Black hole theory tends to employ examples involving individual particles or hypothetical observers' spaceships, and if we limit ourselves to such scenarios the idea of pressure inside the black hole is strange. But what if we imagine a black hole in the middle of an extremely large and homogenous gas cloud? Then we would have gas flowing into the black hole very evenly from all sides and evenly over time. Wouldn't that support the idea of the black hole possibly having internal pressure? I see no reason why the gas, after passing the event horizon, would suddenly be "without pressure". In fact the opposite seems more intuitive to me: as the gas gets compressed inside the BH, it's pressure would presumably rise. Can it rise to the point where it offsets the gravitational pull? Not near the singularity, it would seem, but how about a couple million miles away from it, but still inside the event horizon?

Would like to hear y'aller thoughts.

Singularities as boundaries of spacetime.

Has anyone here fiddled with the idea that black holes and white wholes are boundary conditions to an infinite space-time and what we observe as inflation, big bang and expansion are just the causal structure of a white hole event horizon. Makes sense that we couldn’t observe the beginning, a white holes event horizon would bend spacetime away from it, basically hiding it in an unobservable fold of spacetime.

Idk ive thought about this concept a lot lately, and there’s just something that i find very appealing in the innate symmetry that this would bring in the universe.

I know this is close to pseudoscience but i hope people are still open for a discussion about it.

Question

When they talk about the center of the black hole being the place where no time exists, then how is it possible that some scientists believe that every thing that has been sucked into a black hole goes somewhere? Where does that theory come from? I would just assume it gets destroyed once it reaches that place, because how could space exist without time? And even if it could, I would just suppose that those things would be held in there and then released once the black hole dies.

Another theory is: what if, once it reaches that point, it gets destroyed into very tiny particles and then exits or becomes apart of that black hole itself. Basically, what if it goes nowhere but only changes form? What if black holes really aren’t all that mysterious?

I just find it silly to think that a black hole is like a “portal” that leads to somewhere else, and even if it did lead to somewhere else, I think it would serve as more as a storing center than anything.

I’m interested to know what all the theories are and if any of what I just said can be immediately disproven. I’m very new to learning about black holes, so I’m assuming there’s a lot I don’t know. I’m hoping maybe someone can explain, criticize, or add on to what I just said. I think that would help me understand it better.

What if black holes aren’t ending but part of something bigger?

Alright so this might sound crazy, but hear me out.

I’m not a physicist or anything, just a student who’s really into space, and I’ve been thinking about this idea I’m calling “The Hole Theory.”

What if black holes and white holes aren’t separate things… but actually the same object, just seen from different sides?

Like imagine this:
There’s something that’s 100% one entity, but 50% of it exists in one part of the universe and the other 50% somewhere else. To us it looks separate, but it’s actually one thing.

So applying that idea:

  • Black hole = the “intake” side (pulls stuff in)
  • White hole = the “output” side (pushes stuff out)
  • And what we call a wormhole isn’t really a tunnel you travel through, but more like a hidden connection that makes both ends the same system

So instead of black holes destroying matter, what if they’re actually transferring it somewhere else?

Also this got me thinking about aliens too—
What if we’re searching for life completely wrong?

Like we always look for oxygen, water, Earth-like planets… but that’s just what we need. What if life out there is based on totally different gases or chemistry?

So yeah, this is just a theory I came up with, I know it’s probably incomplete or flawed, but I’m curious:

  • Does anything like this already exist in physics?
  • What parts of this break known science?
  • Could this connect to ideas like wormholes or quantum stuff?

What if we were in a black hole?

So, this is just a theory I made up for fun so please don't dog on me to hard for any possible stupidity.

So, we know of in space a lot of black holes such as Ton618 for example. Well, I was thinking, for several years now, probably starting 2016 or so, things started getting stranger and stranger in the world, and some of us can't help but feel as if the days/years are getting shorter and shorter. (I think I remember that time slows at first but then speeds up in a black hole?)

I know that in space we are seeing things that have happened several years ago, sometimes hundreds of years ago, so what if earth was slowly being sucked into a black hole and we couldn't see it happening yet?

Quantum gravity?

Hello. I wanted to know if a virtual particle could annihilate with a neighbor virtual particle (instead of annihilating with the virtual particle it came from).

I see no reason why not.

And if it can, then that movement is like an edge dislocation in a metal bar that is being bent.

So my question is, what are we bending?

We are bending spacetime, of course.

And that, my friend, is gravity.

Another analogy is the movement of guests in Hibbert s grand hotel paradox.

The movement of guests from one room to the next is the edge dislocation. It allows for more room to be freed. That is a simple way to explain the expansion of the universe.

So, to conclude, the sideway recombining of virtual particles is gravity and is the expansion of the universe.

Thank you for your time.

Last question:

Who can translate that in math to get the Nobel prize?
