This happens every time someone goes into one of these rooms: they disappear leaving behind a random set of items. As for your questions… they are too many for me to address entirely. Then again, what’s a good whodunit if it doesn’t make you work hard to solve the mystery? or is it just classical entropy doing its job? Worded differently, he was assuming the existence of a path through space defined by an algorithm employing some form of infinite recursion (typically halving). Most people I think just refer to the Banks-Peskin-Susskind paper. 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. And these fluctuations are simply those of quantum fields in empty space, containing (apparently) no information at all. They tend to be long and unconvincing, whereas the refutations tend to be short and damning. You’re not hearing about most of them. (1) Two shells of matter are collapsing under their own weight. Of course this is a big mystery. To wit, the dictionary definition of “firewall” is “a wall built to stop the spread of fire” — i.e., a wall through which a fire cannot pass. That is, how did the q…, [Archives] "A central pleasure of doing science is the diversity of the shifting roles one plays while moving throu….
Since the two classes of observers cannot communicate, there is no paradox.
All of that matter remains in the black hole. Why would the interior, if there is an interior of the black hole be three dimensional???

Again, from the accretion disc. As already mentioned, we create a bunch of particles of the same type and with the same quantum state, but that is not the same as “copying” particles. I’m not a physicist and very much appreciate the help your site has given me in getting through (and sometimes beyond) popular books on physics for the “lay” person.
5: Maybe the information is stored in the Hawking radiation?
9: With apologies to Hawking, since neither I, nor anyone I talk to, has a clear idea of what he has in mind, here’s a rough sketch of what I think he’s trying to suggest. I am not anything of a scientist, just reading and trying to get some understanding. It is a completely unrelated issue.
That shouldn’t be a problem for a man who created the TOE. As i understand, X-rays are emitted whenever matter falls into a black hole. This trick did overcome the first hurdle, but there were other bumps down the road. Now, the black hole recap. I’m not well informed, but I just don’t see any mechanism for the info to survive the falling in, let alone the disappearing after. - The Nature of Reality — The Nature of Reality | PBS, Kosmokseen kirjoitettua | Muihin maailmoihin, 10 Mind Blowing Theories About Parallel Universes (Part 2) | A Wallpaper Life, WHAT HAPPENS TO OBJECTS THAT ENTER BLACK HOLES? The concept is utter nonsense. This point, called a singularity, is where the theories of relativity are expected to break down, and become utterly useless at predicting what happens there. 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. So the only way it can be in the Hawking radiation (naively) is if what is inside is copied.
A Halloween Season ‘Taurid Meteor Swarm’ on Tap for 2015? I clearly haven’t thought about some of these details for quite a while. 51:37 Are there any full views of the Earth from satellites?
The theory that the darkest phenomenon in the entire universe gives away highly energetic quantum particles was staggering when it initially came out in ‘74. The history of Physics and of Science in general tells us that when these paradoxes or incosistencies appear, it means that we have bumped into a path towards a breakthrough, an unexpected discovery path towards new theories. Just saw this. A Key Biosignature Called Phosphine has been Discovered in Venus' Atmosphere. He is currently a postdoctoral fellow in the Chennai Mathematical Institute. 33:45 What will Starship land on? Of the many questions they were interested in, one was to ask what quantum theory predicts about black holes. Thank You! Abstract numerical or mathematical relation is useful but not a satisfactory explanation without physical model.
But the captain of the boat will not notice anything when crossing this curve; it is just an ordinary part of the river, whose importance will only become clear when the captain seeks to escape disaster. I guess infinite gravity from infinite mass was on a lunch break. The trick of having a discrete space made out of “cells” of a particular size was actually a precursor of quantum mechanics, as the particular “size” of the “cell” is turned out to be Planck’s constant. poor choice of words! That is why information systems are useful, because of these transformations they can apply to information. Black hole is a place where the pull of gravity is so intense that even light cannot get out. By that I mean black holes would compress matter and energy into an infinitely dense singularity, and didn’t create a seemingly insurmountable information paradox. I did some black hole numerical doodling in Excel, using expressions commonly seen in cosmology papers and ditto websites. The statistical properties of the Hawking radiation, as usual in quantum theory, is the problem – also cannot be solved by non functioning of relativity in black hole situation. The fact that we need to consider molecules to be indistinguishable is a precursor of what Bose bumped into and it later became a major tenet of quantum mechanics. Glad to be of service, Brad! The “temperature of empty space” is ~ 2.73 K (the CMBR temperature), the Hawking temperature of a ~10M⊙ stellar black hole is ~ 100 nK (seven (7) orders of magnitude LOWER than the CMBR temperature), so this radiation would appear to severely violate the second law. The so-called Ultraviolet Catastrophe, or the Rayleigh–Jeans Catastrophe, is what led Max Planck to desesperately find the right equation that would correctly explain Blackbody Radiation, and at doing so, he let the Genie of Quantum Mechanics out of the bottle. Around the mid 1860s, Rudolf Clausius published a paper where he introduced the concept and first formal definition of Entropy. Exactly what is an accretion disc??? I was entirely ignorant of final state QM (and the related Horowitz-Maldacena proposal) until the firewall debate started, for instance. On the contrary, Ludwig Boltzmann was a strong believer and supporter of the idea of atoms, and he was convinced of their existence mostly due to his own research on Statistical Thermodynamics. You referred to the waterfall analogy. I’m not sure if that answers your questions.
