[@alexdevisscher6784]

I don't really understand what the issue was. By definition, the plunging region is between the Schwarzschild radius and the photon sphere, meaning that light can still escape but it can no longer go sideways without falling into the black hole. Why is anyone surprised that light was found to escape from a region that light can escape from?

[@kylelochlann5053]

Well, between the horizon and the ISCO. I think the big news is that in the past we couldn't get observational information about that region.

[@rosverlegaspo6752]

The problem is with the evidence/proof. It is predicted mathematically that such region exist, but we don't have evidence yet that it is actually there. This is essentially the first evidence that such region might actually exist.

[@shawns0762]

There is no Schwarzchild radius. Most people don't know that Einstein repeatedly said that singularities are not possible. In the 1939 journal "Annals of Mathematics" he wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." He was reffering to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". Time dilation is just one aspect of dilation, it's not just time that gets dilated. A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum, this includes the centers of very high mass stars and the centers of the overwhelming majority of galaxy centers. Dilation explains galaxy rotation curves/dark matter. It can be inferred mathematically that the mass at the center of our own galaxy must be dilated. This means that there is no valid XYZ coordinate that we can attribute to it, you can't point your finger at something that is smeared through spacetime. More precisely, everywhere you point is equally valid'. In other words that mass is all around us. The concept of singularities is preventing clarity in astronomy. They were popularized by television and movies beginning in the 1960's. Singularities were not taught in colleges before 1960. Nobody believed in them when he was alive including Planck, Bohr, Schrodinger, Dirac, Heisenberg, Feynman etc.

[@rosverlegaspo6752]

​@@shawns0762 I don't think people actually believe that singularities exist. They are understand to be mathematical artifacts that means our understanding breaks down and that it requires further research. Of course, there are attempts made where singularities are considered and see what comes out of it, but again, it is known that this is just mental exercises rather than the actual description of reality. That is just what we do with Maths. And while singularities are popular in fictional work, doesn't mean people actually believe they are real. Magic is popular, does that mean people think they are real? Not at all. Same with time travel, multiple world/universes, Star Wars, etc.. I don't know why you equate popularity in fiction means people actually believe in it. [Singularities were not taught in colleges before 1960]... but of course. That is actually true for the entire Theory of Relativity. The Theory of Relativity isn't taught in schools until that time. That is practically true with most scientific theories. That is true with Theory of Evolution for example, was still illegal to teach about it in school in the 1920s about 40 years after Darwin published his book). You are not making any point here. This is nothing but a non sequitur. So... You are just tilting at windmills.

You might be confusing the photon sphere with the isco. The photon sphere is at 1.5r_s, the isco is at 3r_s, right? Though if you twiddle the knobs for the full Kerr-Newman-de Sitter metric you might find something with an isco of 1.5r_s. Light should be able to escape from anything inside the isco but outside the photon sphere, though.

[@kylelochlann5053]

[@RedRocket4000]

The innermost stable circular orbit (ISCO), as the name indicates, is the last stable circular orbit with a minimal radius for a particle revolving around the black hole [1]. A particle will plunge into the black hole if its orbit radius is less than that of the ISCO. The object must be orbiting first for this to apply something could pass up to the event horizon and still escape the black hole as long as it not pulled into an orbit. By leaving out the orbit part Anton described the event horizon.

[@cptcosmo]

Anton, here's a hypothetical physics question for you - if you had a theoretical massless capacitor that had the ability to store more energy density than the energy of space time at the Plank Space Geodesic level, would the capacitor turn in to a black hole due to energy mass equivalence?

[@jajssblue]

Not Anton, but do have a Physics background. The answer would be yes. Einstein's equations accept any combination of mass or energy in a volume to produce curvature in spacetime. If that amount of energy or mass exceeds the Schwarzchild limit, then it will create a black hole. As far as our theories can guide us the amount of energy you're describing at the size is enough to reach this limit.

[@claudiaarjangi4914]

Would that be the equivalent of a kugelblitz ?

[@alphaomega154]

answer from "alien" : nope. you could tear a space open but you wont be making a blackhole. blackhole is another MATTER. its not a result of energy density. something earth science still dont get it. and when you tear a space open, you only creating incision to form another space inside. you dont tear open a space into some hole towards some other universe. thats SCIENCE FICTION theory. and yes, THERE CAN BE A SPACE INSIDE A SPACE. is this means our universe can be inside another space? theoritically, but sadly, since there is no edge of the bubble of this universe, its not.

[@ThePdog3k]

Does that promote the idea that this is all just a computer simulation and the guy running it just doesn't have the latest hardware?

[@silphv]

@@ThePdog3k Not particularly no, it just follows from mass-energy equivalence. If you want to come up with stories about why some seemingly arbitrary physical parameters are what they are, whether a black hole starts from mostly mass or mostly energy doesn't really affect that, but basically anything involving Planck scale quantities you can make that analogy to a simulation's limit on render resolution. It's not evidence, but it's a fun mysiticism.

Wouldn’t the observer falling into the black hole see the Galaxy rapidly evolve into eventual “end of the universe” due to the time dilation?

[@kylelochlann5053]

No, there'd be plenty of light falling in after the traveler vanishes at the singularity. In the Kerr geometry the traveler can intercept all of the in-falling light due to the peculiar interior spacetime of a rotating black hole. No, the traveler vanishes at the singularity before it evaporates.

Because, for the outside observer, time slows down as matter gets closer to the BH, I've been trying to imagine why nothing is observed obscuring the event horizon.

Is it that there is nothing to see or don't we yet have the resolution to observe it?

Matter accelerates to speeds close to the speed of light as it crosses the horizon - nothing piles up.

@@kylelochlann5053 I was under the impression that that was from the point of view of the falling body. On the other hand, to the outside observer, because of time dilation, it would seem to become stationary near to the event horizon. That's what I cannot get my head around. In my understanding, the image; not the object; should remain in place almost indefinitely. BUT! What is the light source that provides the image? Oh dear! My brain is hurting again.

[@kylelochlann5053]

​@@farrier2708 The image vanishes, and quite quickly, on the order of about 15 microseconds per solar mass of black hole. The light source has vanished across the horizon. You can find the calculation in any good textbook (e.g. MTW around p. 850). It's true you that the photons emitted just outside the horizon won't reach you for an arbitrarily long time, but they'd be lost in the CMB anyway. A huge hurdle the average person faces in understanding black holes is that they're explained using a system of coordinates that don't cover the black hole. The Schwarzschild-Droste coordinates break down at and can't cross the horizon, so you get incomprehensible interpretations of a bad choice of coordinates (time stops and objects stop at the horizon and whatnot, no such things happen). This is why there's been a resurgence of Gullstrand-Painleve coordinates (the River model, Waterfall coordinates, Rain coordinates, etc) which give an intuitive picture of what's going on.

I then realized my mistake. What I thought was a ringed planet was not. it was a tiny Black Hole, and I just fell past the event horizon. I won’t tell you what happened but now when I play, I have constant fear. It really messed me up when it comes to BHs.

That sounds like an incredibly fun game.... I bought No Man's Sky for some of the same purported reason and was sorely disappointed, but yours sounds better.

@@Deletirium No Mans Sky is better today than before for sure. So if its been awhile def check it out again. Also on Nintendo Switch now. Whats even cooler is LowMemSky.....this is a fan game for the Pico-8 program. Its a retro style 2d pixelated.......No Mans Sky.

It’s going to be a great year in physics.

Especially for lions!

[@TrevNoise]

The ISCO’s distance from the event horizon is determined by a black hole’s spin and mass. A maximally spinning black hole, which the accretion disk is spinning in retrograde to the black hole, would have an ISCO at around 9 times its gravitational radius. Roy Kerr was the one to solve the field equation for a rotating black hole and that wasn’t accomplished until after Einstein’s death.

I am so glad that they are calling it The Plunging Region, which is so much more pictorial and vivid, than Retrieving Area T238.

[@kevinreynolds7500]

So how does Hawking Radiation work with the plunging region? I thought a quark/anti-quark pair had to appear near the event horizon, and one would enter while the other escaped. If the other particle can't escape the plunging region, how does this work?
