This is my contribution to Stephen Hawking’s 60th birthday party. Happy Birthday Stephen! 1 Crisis and Paradigm Shift Stephen, as we all know, is by far the most stubborn and infuriating person in the universe. My own scientific relation with him I think can be called adversarial. We have disagreed profoundly about deep issues concerning black holes, information and all that kind of thing. At times he has caused me to pull my hair out in frustration – and you can plainly see the result. I can… 
SU-ITP 0025 MIT-CTP-3295 hep-th / 0208013 Disturbing Implications of a Cosmological Constant
In this paper we consider the implications of a cosmological constant for the evolution of the universe, under a set of assumptions motivated by the holographic and horizon complementarity
Quelling the concerns of EPR and Bell
We begin with a review of the famous thought experiment that was proposed by Einstein, Podolsky and Rosen (EPR) and mathematically formulated by Bell; the outcomes of which challenge the completeness
Black hole complementarity with local horizons and Horowitz-Maldacena's proposal
To implement the consistent black hole complementarity principle, we need two assumptions: first, there exists a singularity near the center, and second, global horizons are the same as local
The Anthropic Landscape of String Theory
In this lecture I make some educated guesses, about the landscape of string theory vacua. Based on the recent work of a number of authors, it seems plausible that the lanscape is unimaginably large
Very Long Time Scales and Black Hole Thermal Equilibrium
We estimate the very long time behaviour of correlation functions in the pres- ence of eternal black holes. It was pointed out by Maldacena (2) that their vanishing would lead to a violation of a
Of bounces, branes and bounds
Some recent studies have considered a Randall-Sundrum-like brane world evolving in the background of an anti-de Sitter Reissner-Nordstrom black hole. For this scenario, it has been shown that, when
An instructive model of entropy
This article first notes the misinterpretation of a common thought experiment, and the misleading comment that ‘systems tend to flow from less probable to more probable macrostates’. It analyses the
J an 2 00 3 Of Bounces , Branes and Bounds
Some recent studies have considered a Randall-Sundrum-like brane world evolving in the background of an anti-de Sitter Reissner-Nordstrom black hole. For this scenario, it has been shown that, when
Self-Completeness of Einstein Gravity.
We argue, that in Einsteinian gravity the Planck length is the shortest length of nature, and any attempt of resolving trans-Planckian physics bounces back to macroscopic distances due to black hole
Time Dependence of Hawking Radiation Entropy
If a black hole starts in a pure quantum state and evaporates completely by a unitary process, the von Neumann entropy of the Hawking radiation initially increases and then decreases back to zero


The world as a hologram
According to ’t Hooft the combination of quantum mechanics and gravity requires the three‐dimensional world to be an image of data that can be stored on a two‐dimensional projection much like a
Cosmological Event Horizons, Thermodynamics, and Particle Creation
It is shown that the close connection between event horizons and thermodynamics which has been found in the case of black holes can be extended to cosmological models with a repulsive cosmological
Breakdown of Predictability in Gravitational Collapse
The principle of equivalence, which says that gravity couples to the energy-momentum tensor of matter, and the quantum-mechanical requirement that energy should be positive imply that gravity is
Black hole evaporation without information loss
An approach to black hole quantization is proposed wherein it is assumed that quantum coherence is preserved. After giving our motivations for such a quantization procedure we formulate the
Thermodynamics of black holes in anti-de Sitter space
The Einstein equations with a negative cosmological constant admit black hole solutions which are asymptotic to anti-de Sitter space. Like black holes in asymptotically flat space, these solutions
Is there really a de Sitter/CFT duality?
In this paper a de Sitter Space version of Black Hole Complementarity is formulated which states that an observer in de Sitter Space describes the surrounding space as a sealed finite temperature
The stretched horizon and black hole complementarity.
Three postulates asserting the validity of conventional quantum theory, semiclassical general relativity, and the statistical basis for thermodynamics are introduced as a foundation for the study of
Correspondence principle for black holes and strings
For most black holes in string theory, the Schwarzschild radius in string units decreases as the string coupling is reduced. We formulate a correspondence principle, which states that (i) when the
Quantum Gravity In De Sitter Space
We discuss some general properties of quantum gravity in De Sitter space. It has been argued that the Hilbert space is of finite dimension. This suggests a macroscopic argument that General
