Physicists Euphoric but Confused about Black Hole Paradox. The recently proposed idea of “black hole firewalls” has physicists questioning some of their most cherished ideas
The black hole rewall paradox suggests that an observer falling into an old black hole must see a violation of locality, unitarity, or the equivalence principle.
“The putative black hole firewall is one of the hottest problems in physics today, and we hope that our paper makes a significant contribution to the field,” says Page.
By replacing black holes with fuzzballs—dense, star-like objects from string theory—researchers think they can avoid some knotty paradoxes at the edge of physics.
Black holes are involved because they represent the meeting of GR and QM, as both theories can apply in those regions. A large part of the firewall paradox argument is based around the notion of monogamous quantum entanglement: that is, you can only have one kind of entanglement at a time.
The Black Hole Firewall Paradox . By L.D. Molag. Abstract. Until an article by Ahmed Almheiri, Donald Marolf, Joseph Polchinski and James Sully in 2012 it was generally agreed on that an observer freely falling in to a black hole should perceive the space in the vicinity of the horizon as ordinary Minkowski space. This assumption is guided by Einstein’s equivalence principle. The article by
A bstract. Considering the role of black hole singularity in quantum evolution, a resolution to the firewall paradox is presented. It is emphasized that if an observer has the singularity as a part of his spacetime, then the semi-classical evolution would be non-unitary as viewed by him.

29/05/2014 · All black holes have an event horizon (EH), which is the point of no return (gravitationally speaking). Once you pass the EH, you cannot escape the pull of the black hole and as you get nearer and nearer the black hole you will be stretched out in a process called “spaghettification.”

A black hole firewall is a hypothetical phenomenon where an observer falling into a black hole encounters high-energy quanta at (or near) the event horizon. The “firewall” phenomenon was proposed in 2012 by Ahmed Almheiri , Donald Marolf , Joseph Polchinski , and James Sully [1] as a possible solution to an apparent inconsistency in black hole complementarity .

Regarding the black hole information paradox, observer complementarity allowed in-falling information to be cloned at the horizon without any violation of quantum mechanics.
The effect could create a “firewall,” a violent region that would destroy anything passing through it on its way into the black hole. Firewalls create a paradox, though.

But despite the collective angst, even the firewall’s fiercest detractors have yet to find a satisfactory solution to the conundrum. Joe Polchinski , one of the authors who published the paper on the blackhole firewall paradox, has a more technical write up of the subject over on Cosmic Variance .

Guest Post: Joe Polchinski on Black Holes, Complementarity, and Firewalls Posted on September 27, 2012 by Sean Carroll If you happen to have been following developments in quantum gravity/string theory this year, you know that quite a bit of excitement sprang up over the summer, centered around the idea of “firewalls.”
This apparent loss of unitary at the end of black hole evaporation has been dubbed the information loss paradox. A great deal of effort has been spent in devising possible scenarios to preserve unitarity in the context of black hole evaporation [see Fig. 1 for a flowchart].
We argue that the following three statements cannot all be true: (i) Hawking radiation is in a pure state, (ii) the information carried by the radiation is emitted from the region near the horizon, with low energy effective field theory valid beyond some microscopic distance from the horizon, and
I. Review of the information problem and black hole complementarity II. The firewall argument III. Responses and open questions
The actual argument is more complicated but basically the idea is the firewalls are necessary in order for black hole evaporation to be unitary and for effective field theory to be valid just outside the black hole. For what it’s worth I think that it is probably wrong anyway though.

Washington, March 7 (ANI): A new study has dispelled the so-called firewall paradox which shocked the physics community when it was announced in 2012 since its predictions about large black holes contradicted Einstein’s crowning achievement-the theory of general relativity.

It would seem then that either the physical information of an object is lost when it falls into a black hole (information paradox) or objects are vaporized before entering a black hole (firewall

A main spaceship is in freefall above the black hole, and it measures the existence of a firewall before plunging through the horizon. Just before crossing the horizon, but after making the measurements, a smaller escape craft fires off to escape to safety far outside the black hole just in time.
A Black Hole Mystery Wrapped in a Firewall Paradox nyti.ms A paradox around matter leaking from black holes puts into question various scientific axioms: Either information can be lost; Einstein’s principle of equivalence is wrong; or quantum field theory needs fixing.
Scientists have revealed new insights into the life and death of black holes. Their findings dispel the so-called firewall paradox which shocked the physics community when it was announced in 2012
The other assumption overturned by the new research is that black holes have no “hair” – a term coined by John Wheeler to refer to any information about a black-hole’s make-up besides its total mass, charge and angular momentum. – supermassive black hole guitar tab pdf I don’t know, the paper is quite long and I don’t understand most of it.

Curtains down for the black hole firewall paradox: making gravity safe for Einstein again. Posted on 6 March 2013. Research by scientists at the University of York has revealed new insights into the life and death of black holes.
This version of the paradox arises long before a black hole completely evaporates, seems to be the version that has played a central role in quantum gravity, and is genuinely paradoxical. After ex- plicating the paradox, I discuss the implications of more recent work on AdS/CFT duality and on the ‘Firewall paradox’, and conclude that the paradox is if anything now sharper. The article is
Perhaps the information encoded slips out with the Hawking radiation, but this idea runs into another problem: it leads to the black hole being surrounded by a “firewall” of blazing, energetic particles, again something general relativity forbids.
3 collapsing body is behind the horizon, it is incapable of influencing the radiation. The radiation outside the black hole is in a mixed (thermal) state.

A black hole firewall is a hypothetical phenomenon where an observer falling into a black hole encounters high-energy quanta at (or near) the event horizon.
black hole so that we had a normal surface at the horizon, instead of just a vacuum region, then we would evade Hawking’s paradox. But such an alteration is hard to obtain, for a simple reason.
