The Black Hole Wars: My Battle with Stephen Hawking

October 1, 2008
Dr. Leonard Susskind (Stanford University)
Black holes, the collapsed remnants of the largest stars, provide a remarkable laboratory where the frontier concepts of our understanding of nature are tested at their extreme limits. For more than two decades, Professor Susskind and a Dutch colleague have had a running battle with Stephen Hawking about the implications of black hole theory for our understanding of reality — a battle that he has described in his well-reviewed book The Black Hole Wars. In this talk Dr. Susskind tells the story of these wars and explains the ideas that underlie the conflict. What's at stake is nothing less than our understanding of space, time, matter and information!

General Relativity Lecture 7

(November 5, 2012) Leonard Susskind continues the discussion of black holes in depth using coordinate transformations and diagrams to develop an intuitive understanding of black hole physics.

This series is the fourth installment of a six-quarter series that explore the foundations of modern physics. In this quarter Susskind focuses on Einstein's General Theory of Relativity.

Originally presented in the Stanford Continuing Studies Program.

Black Holes and the Fundamental Laws of Physics - with Jerome Gauntlett

Black holes are extraordinary and may even hold the key to unlocking the next phase in our understanding of the laws of physics.

Black holes are amongst the most extraordinary objects that are known to exist in the universe. Jerome Gauntlett will discuss their fascinating properties and describe the dramatic recent observations of black holes using gravitational waves. He will also explain why it is believed that black holes hold the key to unlocking the next level of our understanding of the fundamental laws of physics.

Jerome Gauntlett is a professor of theoretical physics at Imperial College. His principal research interests are focussed on string theory, quantum field theory and black holes. Most recently he has been investigating whether string theory techniques can be used to study exotic states of matter that arise in condensed matter physics. He was Head of the Theoretical Physics Group at Imperial from 2011-2016.

He was the theoretical physics consultant for the film The Theory of Everything and he has an Erdos-Bacon number of six (having written a paper with Shing-Tung Yau and appeared in the film Windrider with Nicole Kidman).

Note: I select clips with insights from these much longer conversation with the hope of helping make these ideas more accessible and discoverable. Ultimately, this podcast is a small side hobby for me with the goal of sharing and discussing ideas. For now, I post a few clips every Tue & Fri. I did a poll and 92% of people either liked or loved the posting of daily clips, 2% were indifferent, and 6% hated it, some suggesting that I post them on a separate YouTube channel. I hear the 6% and partially agree, so am torn about the whole thing. I tried creating a separate clips channel but the YouTube algorithm makes it very difficult for that channel to grow unless the main channel is already very popular. So for a little while, I'll keep posting clips on the main channel. I ask for your patience and to see these clips as supporting the dissemination of knowledge contained in nuanced discussion. If you enjoy it, consider subscribing, sharing, and commenting.

Leonard Susskind is a professor of theoretical physics at Stanford University, and founding director of the Stanford Institute for Theoretical Physics. He is widely regarded as one of the fathers of string theory and in general as one of the greatest physicists of our time both as a researcher and an educator.

Black holes! From Stephen Hawking to Interstellar, black holes are mammoths in the world of science AND sci-fi. But what exactly IS a black hole? Do events happen inside black holes? Are black holes really a hole? Are black holes really black?! Join Gabe on this week’s episode of PBS Space Time as he debunks popular black hole misconceptions, and rethinks what the term, ‘black hole’, even means. Thought you knew what a black hole was? Think again!

Black Hole wars - Leonard Susskind

The Black Hole Wars
Speaker(s): Leonard Susskind
Abstract: The strange paradoxes and puzzles of the quantum behaviour of black holes and the things that fall into them led to a spirited battle of ideas between Stephen Hawking, Leonard Susskind and other scientists. Resolving the debate may change our entire understanding of space, time, matter and information – is the entire world, for example, a quantum hologram?
