Cosmology and Black Holes

Winter, 2011

In the last of course of this series, Leonard Susskind continues his exploration of string theory that attempts to reconcile quantum mechanics and general relativity. In particular, the course focuses on string theory with regard to important issues in contemporary physics. Topics include: 1) the impact of string theory on the pursuit of black holes; 2) the string theory landscape and the implications for cosmology; and 3) the Holographic Principle and its applications.   (Image credit: KIPAC at Stanford University)

Lectures in this Course

  1. 1

    Special relativity and string theory

    Professor Susskind describes the special theory of relativity and focuses on showing how it connects to string theory. He considers concepts such as space-time and some of Einstein's original concepts.
  2. 2

    Black holes

    Professor Susskind present the mathematics of a black hole.
  3. 3

    Black hole horizons

    Professor Susskind describes the geometry of a black hole near the event horizon.  He describes how standard concepts from quantum physics can explain the physics that occur at this point.
  4. 4

    Black holes and light

    Professor Susskind again discusses black holes and how light behaves around a black hole.  He uses his own theories to mathematically explain the behavior of a black hole and the area around it.
  5. 5

    Black hole entropy

    Professor Susskind describes how string theory gives a resolution to the question regarding the entropy of a black hole.
  6. 6

    Black hole entropy 2

    Professor Susskind continues the presentation of the theory behind calculating the entropy of a black hole.
  7. 7


    Professor Susskind discusses the concept of cosmic horizons as well as the relationship between ultraviolet and infrared light.
  8. 8

    More black holes and horizons

    Professor Susskind completes the course with a broad discussion of black holes and horizons.
