Episode notes

quantum mechanics says that in principle you should be able to measure all of the radiation that comes out and reconstruct the book. So is it possible that somehow when the book falls into the black hole its information is duplicated into the outgoing radiation and we get it that way? Well that's an interesting question. The problem with it is it's known in quantum mechanics that you cannot really duplicate information. You can't even at least within the usual rules of quantum mechanics save the situation by duplicating the information. On the other hand what if you could duplicate the information but nobody could ever in principle detect the fact that you duplicated the information. This is after all a thought experiment just so the audience

For decades now physicists have been struggling to reconcile two great ideas from a century ago: general relativity and quantum mechanics. We don’t yet know the final answer, but the journey has taken us to some amazing places. A leader in this quest has been Leonard Susskind, who has helped illuminate some of the most mind-blowing ideas in quantum gravity: the holographic principle, the string theory landscape, black-hole complementarity, and others. He has also become celebrated as a writer, speaker, and expositor of mind-blowing ideas. We talk about black holes, quantum mechanics, and the most exciting new directions in quantum gravity.

He has made important contributions to numerous ideas in theoretical physics, including string theory, lattice gauge theory, dynamical symmetry breaking, the holographic principle, black hole complementarity, matrix theory, the cosmological multiverse, and quantum information. He is the author of several books, including a series of pedagogical physics texts called The Theoretical Minimum. Among his numerous awards are the J.J. Sakurai Prize and the Oskar Klein Medal.
