Penrose diagram showing the layered structure of the near horizon region of an ADS black hole

Computational Complexity and Black Hole HorizonsLeonard Susskind(Submitted on 23 Feb 2014 (v1), last revised 25 Feb 2014 (this version, v2))Computational complexity is essential to understanding the properties of black hole horizons. The problem of Alice creating a firewall behind the horizon of ...Tags: Penrose diagram, layered structure, near horizon region, ADS black hole, susskind

### New Revolutions in Particle Physics: Basic Concepts by L. Susskind

Leonard Susskind gives the first lecture of a three-quarter sequence of courses that will explore the new revolutions in particle physics. In this lecture he explores light, particles and quantum field theory.Leonard Susskind, Felix Bloch Professor...Gedanken Experiments involving Black Holes

Gedanken Experiments involving Black Holes L. Susskind, L. Thorlacius (Submitted on 20 Aug 1993) 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 d...Tags: gedanken experiments, black holes, susskind

The Stretched Horizon and Black Hole Complementarity

The Stretched Horizon and Black Hole Complementarity L. Susskind, L. Thorlacius, J. Uglum (Submitted on 16 Jun 1993 (v1), last revised 28 Jun 1993 (this version, v2)) Three postulates asserting the validity of conventional quantum theory, semi-classical general relativity and the sta...Tags: stretched horizon, black hole complementarity, susskind
