I am not arguing for certainty of singularity, quite the opposite. I stated that we seriously suspect the math yielding us that singularity is wrong, we just cant figure out anything more correct yet. Personally I think the geometry of spacetime inside blackhole gets all twisted up, bubbling like a boiling pot of water, but my guess is as good (probably worse) than anyone elses. >when blackhole density falls below the density of the universe Which one? The outside one? Density of whole universe? Its local surroundings? Are you counting unknown pressures of stuff we, for pure lack of understanding what the hell it even is, call dark energy/mass? The "blackhole less dense than the rest of the universe" seem like just another mathematical artefact that couldnt, for any reason, exist in real world. Not saying thinking about it is wrong, but imho more could be gained by thinking "well it surely cant exist, so what mechanism are there that stops this", instead of "this math says that, so lets subdue our whole theory to it". Very same scenario as the singularity inside. Just because math works for something doesnt mean it is like that. In science history we had plenty of equations that worked, until we discovered some edge case where it suddenly didnt. I think its safe to bet interiors of blackholes, or blackholes encompassing whole universe, are prime candidates for such edge cases where our pressumed math models just break down. The fact that our current math models are returning infinities, we are generally accepting that to be the case.

> but imho more could be gained by thinking "well it surely cant exist, so what mechanism are there that stops this" Well, the universe Schwarzschild radius is massively larger than the universe itself, so math says we live in a black hole. It is true this might be a mathematical artifact, but it could also be how it actually works and the observations we make in our universe and about big bang is how a black hole looks on the inside. I don't think you should just assume the math is wrong here and throw away those observations of the inside of a black hole. Sure you should be open to that being wrong, but at least to me that is far more believable and interesting to study, then you can try to connect what we observed about the big bang with a black hole etc. If I go through enough of these forum discussions maybe I develop this long enough, and then maybe I'll take a serious attempt at solving the math to combine the two, since nobody else will do that. I was called a genius by both my physics and math professors, so it is possible I can solve it since I have good intuition for physics and good skills at math, most people who work in physics just have one of those, even though likely I'll fail, but it would be fun to try. What makes me believe such an attempt could work is that it could lead to a different math for gravity and black holes at small scales, and thus lead to a unified theory of QFT and GR. If I manage to do that then I could convince physicists to adopt the new interpretation of GR. Current attempts of unifying those two has started from the QFT side and tried to incorporate current GR theories, but they all failed. But I haven't seen many try to attempt that from the GR side and unify that with QFT, so maybe that would yield some results. Anyway, I don't think that professional physicists will solve this, since they are too occupied focusing on publishable results rather than solving the core issue. What I write here isn't publishable, so no physicists would even think about working on it. It is how GR was invented by Einstein even though he wasn't a physics researcher, sometimes you need a big jump done by an outsider. GR wasn't on anyone's radar when Einstein suggested it, likely it would never have been discovered without Einstein, or at least take centuries. The gravity formula you get from GR doesn't need space time distortions to reproduce, so theoretical physicists would just update the gravity formula to match observations without creating a new interpretation of what that means. Newtons gravity formula doesn't come with an interpretation, updating it to match new data is exactly what they did with dark matter and dark energy since it is just a formula, so I see no reason why gravity would be any different without Einstein's GR. Black holes would just be a part of that dark matter. Edit: Anyway, for me it is fun to argue on forums, so that is the best way for me to think and develop theories. Typically I don't really believe what I say, so part of my posts is to find evidence for it and try to convince myself that what I say is true. So I refine things quite a bit in every discussion.

  I got a good idea: Nothing ever passes the event horizon, rather as an object gets close to the event horizon the combined Schwarzschild radius of the black hole and the object will at some point cover the object, meaning the event horizon would expand and engulf the object instead of the object moving through it. This would totally change the math around the event horizons, since then space doesn't need to be connected between the interior and exterior of the hole. The outside of the hole still would work the same, but as the hole bends space to engulf objects rather than objects moving through space to enter the hole you get a very different way to look at the interior. Not sure how the math for that would work, but it is fun to think about. Also this is obviously true, for any particle that point would happen before it enters the current radius, so the hole expands out, even if it is by an extremely small amount that is still enough to change the math around the event horizon singularity. Edit: The main thing this changes is that now the particle doesn't have to accelerate to the speed of light as it passes the event horizon, as the event horizon expands to cover it rather than it accelerating through. As you can understand that is a massive change, it means that space inside the black hole could remain sane without breaking GR. The infinite time dilation you get at those gravity levels is why the math for space and time inside of black holes is so strange, remove that and you can get back to sanity.

    Then we could assume that the interior of the black hole looks just like our universe, since our universe is smaller than its Schwarzschild radius. Basically we want to show that the interior space time of a black hole can be relatively flat. The problem to solve then is to calculate what happens at the edge of such a universe, and try to match that with what happens at the edge of a black hole, since those two would be the two sides. To unify that with QFT you'd have to include the particle collapse (or entanglement if you want to use the many worlds wording), where the quantum field would collapse to where the particle suddenly is inside the black hole instead of outside. I have long theorized that there is no way to unify the theories without using quantum collapses, so black holes could engulf particles via quantum field collapses only. The math for such collapses isn't fully established though, so it would need to have more theories on the quantum side as well. But at least that means nobody has developed a theory like this yet. The main calculation would be to calculate the probability of a particle collapsing into the black hole over time, by calculating how large part of the particle field is inside the critical area were it would be inside the new black hole radius. The particle and the black hole would get entangled for a bit where it is both inside and outside the black hole at the same time, and then the field collapses and it is fully inside. I think that can actually work! Then the black holes event horizon is a natural quantum effect, which could potentially provide the missing link between the two.
