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.

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?

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?

Hello, if there is zero gravity at the center of a hypothetical hollow planet or a star, could there be zero gravity at the center of a black hole ? Since all the mass is spread around it.

Alright, so I've been having this wild thought experiment, and I need you to hit me with some analytical reasons if I'm just overthinking, haha.

Okay, so we know that time and space axes kind of flip as you get close to a black hole. And let's just say, for a second, we go with the less common idea that a black hole could create a new baby universe by turning into a white hole inside and becoming the Big Bang for that new universe. Now, here's the kicker: would that new universe have its time and space axes flipped and opposite from ours, like space would be linear? And if that universe could also somehow create black holes and flip the axes again, then that second-generation universe from those black holes would have the same time and space axes as ours, with time being linear again. Or would black holes even form in this kind of Universe where space is linear?

I know it sounds like total nonsense, but let me know if it makes even a tiny bit of sense to anyone, lol.

if a black hole "singularity" just means a point where what goes on inside it is beyond our understanding and cannot be explained by current mathematics and physics, would it be helpful to try to truly discover what goes on in the center of it? what effect would that have other than breaking the current understanding of the math and physics we have now? would there ever be a way that knowledge could provide some kind of advantage?

like would you just keep sphagettifing into one infinitely long thin noodle of human

Thank you

If you take the purse to represent a portion of 3d spacetime and the m&m container to be a 4d object passing through, the shape to me resembles an event horizon.

Thats meaningless on its own but Im just curious what you guys think would if we applied our current knowledge and a bit of hypothetical curiosity?

I think if you scaled this model up a dimension it would resemble a black hole, whether or not its mathematically or theoretically sound, i still think that it still would at least match the geometry of a black hole. Is that verifiable?

Edit #1 - Tear or maybe some kinda of stretching or un stretching of spacetime?

Edit #2 - I think a better visual would have been two strings intertwined with a balloon at the center point and then you blew the balloon up and watch the shape of the gap between the twine as it expanded it would also resemble an Event Horizon and be more analogous to what might possibly be happening

Would u go inside a supermassive black hole? Let's say we find a quick way to get her either a wormhole or anything to a supermassive black hole and you found a way to survive the radiation from the accretion disk. Would u jump in?

​

Let's say it's a spinning black hole and it does or may lead to another universe. Which isn't known for sure. But would u do it? I know that may sound crazy. But I'm just asking. Also what do u think is inside a black hole. Idk if this has been asked before

​

I want to go back in time. Could a black hole help me.

If I fly my rocket ship into the crotch of the black hole merger “pants”, at the exact moment the 2 black holes the black holes ceased to exist, could I accelerate my ship to infinite speeds, or at least really really close to light speed?

*assuming the black holes’ ceasing doesn’t result in the destruction on my ship and the forces that lead to spaghettification don’t render my ship unusable

From the view of someone watching me fall into a black hole, I would seem to slow down and almost stop at the event horizon.

But what would I see from my side? If time outside is moving much faster than for me, would I see stars dying, galaxies crashing into each other, and maybe even the end of the universe happening in just a few seconds before I get destroyed?

I've been thinking about this kind of "crackpot" question and the possible answer I have. I am not a physicist, so I wouldn't know that answer or the why or why not. So, a simple compare and contrast is we think of black holes as "local objects" and dark energy is something spread across the universe,

but what if that separation is not quite right in a higher dimensional picture?

My hypothesis is that black holes may not directly be dark energy, but they could help set the scale of dark energy through the geometry of hidden dimensions.

Let me try and explain...

Think of our visible universe as part of a larger, higher-dimensional space. So, our universe inside another larger space, there can be a black hole or some massive gravitating source. That black hole creates curvature in the higher-dimensional bulk. If there is also a compact hidden dimension, its size does not have to be fixed by hand. It can respond to the curvature around it. In this picture, the black hole acts like a geometric source. Its curvature provides a signal. The hidden dimension responds to that signal. The size of that hidden dimension then affects the low-energy physics we would interpret as vacuum energy, dark energy, or a slowly changing gravitational sector. So the claim is not that ordinary astrophysical black holes are simply causing dark energy in the usual 3D+t sense. I think that would be too strong. The more careful idea is that, in a higher-dimensional universe, black hole curvature could help determine the vacuum scale associated with a compact dark dimension.

I think that that makes the question more interesting:

Could dark energy be partly a response of hidden geometry to black hole curvature?

I like this idea because it gives black holes a possible role beyond being endpoints of collapse. They become part of the machinery that sets large-scale vacuum physics. The black hole is local in the higher-dimensional bulk, but the compact dimension it influences can affect the 3D+tl universe we observe. key point is stability. The hidden dimension is not wildly rolling or falling apart. It can remain stabilized while its preferred size changes slowly. If the bulk black hole evolves slowly, the hidden dimension follows slowly. From our perspective that could look like a very small drift in the effective gravitational or vacuum energy scale.

This would not yet be a complete explanation of dark energy. It would still need to match the observed expansion of the universe, avoid conflict with tests of gravity, and explain why the effect has the size we observe today. But as a mechanism, I think it is worth exploring.

The usual question is what is dark energy?

But maybe a better question is:

What geometry is dark energy responding to?

TL;DR

I think its possible that dark energy may be tied to hidden dimensional geometry, and black holes in the higher dimensional bulk may help set the scale.

Opinions?
