AFAIK, the mass of a black hole is concentrated on a point called the singularity, this is the reason for its extreme gravitational pull. So for black holes to behave the way it does, it needs a singularity. Are you suggesting that this singularity is made of dark matter ?
How does this dark matter singularity become that foggy patches shown in the NASA Hubble map ? To me, this doesn't seem to solve dark matter but just complicates things even more, lol 😂
AFAIK, general theory of relatively is proven. I don't know if singularity makes space-time curvature infinitive, that's kinda confusing because infinity a theoretical. For example, we consider sun's rays as parallel even though its not at an infinite distance from earth, so the context matters.
Because I don't know the mathematics behind all this, I'm not sure which infinity they meant. Its possible that they meant the true theoretical infinity. I've heard the quote "black holes are where god divided by zero", so there's definitely some weird mathematics going on. I think Hawking radiation disproved that statement, IDK 🤔. Its been a while since I last heard about black holes, haha. Anyway, these things are weird AF, they're too dense for us to grasp ;)
> Why is my theory making things more confusing
Singularity is more like a point, so calling it a "ball" is kinda misleading. Also, there's a lot of unknowns about dark matter, you're just making a lot of assumptions here, that stars convert matter to dark matter when they explode, that black holes convert matter to dark matter when it swallows something, etc. There's no need to make it this complicated when you can explain everything using a singularity made of normal matter, not dark.
Its not actually a hole, you know that right. It just pulls everything in to the singularity, that's just an extremely powerful gravity. And for where does this matter go, there are theories saying its like wormhole, so it spews everything it swallows somewhere else. There's also Hawking radiation, which is more widely accepted I think. It solves this information paradox, because it shows that black holes radiate away.
"It just pulls everything in to the singularity" - so you're saying it pulls stuff into that "point"? Then why are these black holes bigger, smaller, have a shape, a mass?
I'm no expert, but from what I understand, what they mean by the size is the event horizon. The event horizon is a boundary inside which light can no longer escape. So intuitively, this event horizon should expand when the mass increases because gravity increases with mass.
BTW, from what I know about black holes, they don't have a shape. I've heard about spinning black holes, but never a cube/pyramid shaped one 😁
Oh yeah, the singularity might be of any shape, we don't really know much about the inside, everything after the event horizon is just black
Most black holes I've seen in pictures and stuff have a spherical event horizon, and I think the disk you're mentioning is things orbiting these black holes that glow because of their heat, that video explained it. If the event horizon is spherical, the stuff inside should be spherical too right ? I don't know enough about gravitational fields to know
Oh yeah, the singularity might be of any shape, we don't really know much about the inside, everything after the event horizon is just blackCould also be that there is no such thing as singularity...
If the event horizon is spherical, the stuff inside should be spherical too right ?Sounds right to me but how can we know :D. If I think about my black ball theory then yes haha.
> Could also be that there is no such thing as singularity...
Could be, but the mass of the black hole still has to exist somewhere inside the event horizon. The idea of a singularity is probably used to explain the extreme gravitational pull, maybe it'll have less space-time curvature if the mass is spread around VS on a densely packed point. So more space-time curvature means more gravity. I'm still not sure how scientifically proven this singularity thing is, this is my understanding.
That video is talking about the same thing I said earlier. So its confirmed, dense objects have higher gravity 🙂
> this mass of a black hole is not that black disk we observe, but a tiny point in the middle.
Of course, the event horizon is not a physical boundary like the boundary of a ball, its a point after which light can no longer escape from the gravity of the black hole. And gravitational field is always much larger than the size of the object, think about sun pulling on earth.

I don't know if its just a theory, what's happening inside a black hole we can't know, but we can observe the surroundings to prove that there's extreme gravity there that even light can't escape. Remember, light only moves in a straight line, but massive objects can bend the space-time curvature to bend its path. This has been proven, I recommend you look more into general theory of relativity, its very interesting :)
So when a star dies and it collapses under its own gravity, 3 things can happen. If the repulsion between electrons are able to prevent the collapse, then it becomes a white dwarf. If the repulsion between neutrons stop the collapse, then it becomes a neutron star. But if the star is too massive and even those nuclear forces can't stop the collapse, then there's no other force known to science that can stop it from collapsing on its own. So it collapses into an infinitely dense point !
The reason why we can't compress everything into a point in real life is the same reason why I can't push my hand through the wall. The atoms/electrons in my hand repulses the atoms/electrons in the surface of the wall. But inside the black hole, the gravity is so strong that it overcomes these repulsion between atoms, so there's no other force to prevent it from collapsing into a point.
No matter how much stuff you throw into a black hole, the singularity will remain the same size. The mass of the black hole will increase and thus the gravity increases, so the event horizon will get bigger. But the actual size of the singularity won't increase, it'll just collapse everything into that infinitely dense point. This is just insane 🤯
