A bstractWe 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 (iii) the infalling observer encounters nothing unusual at the horizon. Perhaps the most conservative resolution is that the infalling observer burns up at the horizon. Alternatives would seem… Expand
Comment on the black hole firewall
Recently, it has been argued that black hole complementarity is inconsistent by showing that, for an infalling observer, it would lead to the existence of a firewall near the black hole horizon,Expand
Comments on black holes I: the possibility of complementarity
A bstractWe comment on a recent paper of Almheiri, Marolf, Polchinski and Sully who argue against black hole complementarity based on the claim that an infalling observer ‘burns’ as he attempts toExpand
Complementarity endures: no firewall for an infalling observer
A bstractWe argue that the complementarity picture, as interpreted as a reference frame change represented in quantum gravitational Hilbert space, does not suffer from the “firewall paradox” recentlyExpand
Firewall or smooth horizon?
Almheiri, Marolf, Polchinski, and Sully pointed out that for a sufficiently old black hole (BH), the set of assumptions known as the complementarity postulates appears to be inconsistent with theExpand
Black hole complementarity and firewall in two dimensions
A bstractIn connection with black hole complementarity, we study the possibility of the duplication of information in the RST model which is an exactly soluble quantized model in two dimensions. WeExpand
The firewall transformation for black holes and some of its implications
A promising strategy for better understanding space and time at the Planck scale, is outlined and further pursued. It is explained in detail, how black hole unitarity demands the existence ofExpand
The Two Faces of Hawking Radiation
What happens when Alice falls into a black hole? In spite of recent challenges by Almheiri et al. — the so-called "firewall" hypothesis —, the consensus on this question tends to remain "nothingExpand
An uneventful horizon in two dimensions
A bstractWe investigate the possibility of firewalls in the Einstein-dilaton gravity model of CGHS. We use the results of the numerical simulation carried out by Ashtekar et al. to demonstrate thatExpand
Black Holes: Thermodynamics, Information, and Firewalls
Black holes have presented us with some of the most baffling paradoxes in physics. From their original conception as dark stars, they have come to be understood as physical systems with their ownExpand
The black hole information paradox and highly squeezed interior quantum fluctuations
Almheiri, Marolf, Polchinski, and Sully argued that, for a consistent black hole evaporation process, the horizon of a sufficiently old black hole should be replaced by a "firewall" at which anExpand

Complementarity, not Firewalls
In this note I argue that a version of complementarity is possible which evades the need for the "firewalls" recently proposed by Almheiri, Marolf, Polchinski, and Sully to burn up observers fallingExpand
Singularities, Firewalls, and Complementarity
Almheiri, Marolf, Polchinski, and Sully, recently claimed that once a black hole has radiated more than half its initial entropy (the Page time), the horizon is replaced by a "firewall" at whichExpand
Complementarity is not enough
The near-horizon field B of an old black hole is maximally entangled with the early Hawking radiation R, by unitarity of the S-matrix. But B must be maximally entangled with the black hole interiorExpand
Gedanken experiments involving black holes.
Analysis of several gedanken experiments indicates that black hole complementarity cannot be ruled out on the basis of known physical principles. Experiments designed by outside observers to disproveExpand

The black hole information paradox forces us into a strange situation: we must find a way to break the semiclassical approximation in a domain where no quantum gravity effects would normally beExpand
Remarks on the black hole information problem
String theory provides numerous examples of duality between gravitational theories and unitary gauge theories. To resolve the black hole information paradox in this setting, it is necessary to betterExpand
