# black hole information paradox

My illustrations can’t illustrate how space and time are warped; for instance, to understand the whole story, you have to account for the fact that clocks inside the black hole run very differently from clocks just outside, which in turn run very differently from clocks far away. So is it possible that it resides inside the event horizon somewhere or perhaps at the event horizon itself encoded as the most basic information of itself. Perhaps the conjecture has just evolved into something like this pretty statement: “The ‘no hair theorem’ … encodes our failure to find any alternative to the black hole geometry” (They will certainly discuss quantum operations and I think the Lindblad equation.) It is very clear that with this type of problems, having enough complexity, you need to work with the equations to get any useful and theoretically valid insights. (It is not a phrase which seems to get used in this context). Do your homework. Particle Physics: Why do it? And the accelerating observer also sees a horizon, almost exactly like a black hole horizon; because information about what is happening behind the horizon can’t catch up with the accelerating observer, so (unless s/he stops accelerating, which s/he can always choose to do) that person will never learn what happened behind the horizon. I don’t think many people still believe that the No-Hair Conjectures, which are true for classical black holes, are true of quantum black holes.

Unfortunately, I’ve learned what I know about it much the way Avery has, from some quantum information notes and some papers. So the intuition you’re relying on fails, eventually, because in some way the infalling observer comes back out (scrambled) in a FINITE time. You’re worrying about something that has nothing to do with the physics of Hawking radiation. Regarding the fact that we do not have direct experimental confirmation of Hawking radiation, which is true, that does not invalidate the theory.

We have made great advances in physics in the last 120 years or so, propelled by the twin revolutions of general relativity and quantum theory. There are lots of thought experiments about black holes, but any real experiment should help a lot. Specifically, observers who remain outside the black hole see the information accumulate at the horizon, and then come flying outward in the Hawking radiation.

First, let’s talk information.

He also believes that a similar process occurs in the observable universe on its entirety which would mean that we live in a holographic 3D universe on top of a 2D space encoded with information. A basic knowledge of math will allow anyone to see that Crother’s proofs are essentially irrefutable and reveal the intrinsic flaws in the math of “black holes”. Any chance that the uncertainty principle and information leakage from a black hole might be related? The first problem that showed up was rather thorny: we knew by then that Entropy, using Clausius’ definition, has a finite value. Besides, strict causality does not apply to quantum field theories. Translation often has to proceed in two steps… let me know how you approach it. You’re not hearing about most of them. But that approach doesn’t usually leave anyone satisfied.

In the black hole formula, the adimensional factor is the area of the event horizon divided by the square of the Planck length (there’s also a constant with the value of 4 dividing). Theoretical calculation: General relativity predicts gravitational waves. As for your questions… they are too many for me to address entirely.

However, real black holes, such as the big one in the center of a galaxy, absorb incoming matter (and radiation?

You said several things about black holes and accretion disks that suggest you are confused or misinformed. As Matt also points out, with a 50/50 virtual +/– mass contribution the net gain/loss OUGHT to be zero. The presence of iron at the core is equivalent to ever famous apocalyptic phrase “the end is near”, The atomic structure of iron is highly stable and the energy & force required to fuse two iron atoms into nickel is insane which means that at this stage the star cannot sustain its fusion engine & starts giving away to gravity, The number 1.4 times the mass of sun is quite important in astrophysics because it is key to understanding the evolution of stars in the universe. Pingback: WHAT HAPPENS TO OBJECTS THAT ENTER BLACK HOLES? That means that we can apply a linear transformation, a translation of time of the form t’ = t + delta_t, or a translation of space of the form x’ = x + delta_x and the corresponding physical quantities will be conserved. Which means this idea can pan out only if we discard the principle of locality.

This is wrong: No particle can exit from the event horizon, no particles could come out of the black hole. It gets to rotating really (relativistically) fast, and – voila. multiple jets of plasma have been confirmed emanating from these bodies. Unfortunately, I think that your description of quantum theory is a bit misleading. I wonder when physicists eventually give up and start looking for a better theory? The force of gravity is so weak when compared to these immensely powerful structures. If quantum mechanical effects in black holes are significant enough for black holes to strongly behave according to the rules of QFTs, we could argue that the multiple stories of QFTs work in favor of the idea that all black holes are really different and unique. Thermal radiation is purely random, and can’t encode any information. (3) Negative energy is an idea generally considered speculative today, 38 years after Hawking’s paper was published, That’s completely wrong: negative energy is the key to understanding why there is anything interesting in the cosmos. But crudely speaking, by the halfway point, so much information has departed the black hole in the Hawking radiation that there’s not enough left at the horizon for holography to represent the black hole’s interior. But I need to get my facts straight first.

The issue has to do with information storage and which objects are quantum-entangled with which other ones. | Of Particular Significance, Pingback: Learning Lessons From Black Holes | Of Particular Significance. We live in a 3D universe and time (Schrodinger’s time) is merely a quantization of causality. If the time in outside universe moves faster and faster as he approaches the horizon, how can he pass it before it’s gone? Most of matter will evaporate into radiation before it could even reach their event horizont, which does behave like the firewall in this way.

33:45 What will Starship land on? He seems to suggest that the complexity itself destabilizes the horizon and allows the information, having been scrambled inside the black hole, to leak back out. Once the boat passes a curve of no-return (see Figure 3), its engine will be unable to fight the current, and it will inevitably go over the waterfall. What I meant was that quantum state can suffer decoherence although overall unitarity has to be conserved. Complex systems, like weather, can exhibit chaos, which can make them unpredictable even before you think about quantum theory. Go figure! At the time, scientists were content with the fact that they could have a mechanical model of the statistical behaviour of billions of molecules of (ideal) gas and be able to predict the values of thermodynamical properties of the gas, even though they did not realize the major significance of these “tricks” that were used.

The issues are related to the fascinating fact that there are extremely strong analogies between the entropy and temperature of hot systems [like a gas of molecules in a box] and black holes — some of the equations are actually the same. This pilot plant could be either real or a simulation, but this is major step in the long process that would get you to a proper design for a real plant, a complete factory capable of producing a certain chemical product or products with economic efficiency. Imagine a man goes inside a room and gets locked in. large (I was not trying for self-promotion here but rather just including the references)…thanks…Emil. The field of theoretical physics that tries to describe gravity according to the principles of quantum mechanics is called quantum gravity and it speculates the presence of an elemental particle called graviton which is massless, has a quantum mechanical spin of 2, and electrically neutral to mention few of its predicted properties. You stated that Zeno is right that one can always divide the remaining distance in half…My argument is that you cannot continue the recursion once you reach the boundary defined by the infinitesimal volume Pingback: In Memory of Joe Polchinski, the Brane Master – Silgate Solutions. It can’t be used to predict precisely what will happen, but only the probability for any particular thing to happen. That is Unruh radiation. Now it’s all 50 shades of grey, with the laws of physics bending under other laws of physics. Let’s see. Post was not sent - check your email addresses! Of course, it may simply be that quantum theory is incomplete, and that the physics of black holes forces us to extend that theory, much as Einstein extended Newton’s laws of motion in his theory of relativity. My conclusion was that this type of structure, if it exists anywhere in the universe, would likely only exist near singularities or at the boundary of the universe. If so, wouldn’t the information also be emitted with infinite possible results of variable information unless observed/operated on beforehand? Bousso discusses it in several of his recent firewall papers, and argues that it doesn’t seem to work. This is to be expected: the radiation also comes from just outside of the black hole, so the most it can tell us will have to do with these three properties. Why is the Tevatron So Busy with Hints of New Physics? It’s also possible for a black hole to emit a photon and absorb an electron-positron pair, or vice versa.
