The Black Hole War: My Battle with Stephen Hawking to Make the World Safe for Quantum Mechanics
What happens when something is sucked into a black hole? Does it disappear? Three decades ago, a young physicist named Stephen Hawking claimed it did-and in doing so put at risk everything we know about physics and the fundamental laws of the universe. Most scientists didn't recognize the import of Hawking's claims, but Leonard Susskind and Gerard t'Hooft realized the threat, and responded with a counterattack that changed the course of physics. THE BLACK HOLE WAR is the thrilling story of their united effort to reconcile Hawking's revolutionary theories of black holes with their own sense of reality-effort that would eventually result in Hawking admitting he was wrong, paying up, and Susskind and t'Hooft realizing that our world is a hologram projected from the outer boundaries of space.
A brilliant book about modern physics, quantum mechanics, the fate of stars and the deep mysteries of black holes, Leonard Susskind's account of the Black Hole War is mind-bending and exhilarating reading.
About the Author
Leonard Susskind has been the Felix Bloch Professor in theoretical physics at Stanford University since 1978. The author of The Cosmic Landscape, he is a member of the National Academy of Science and the American Academy of Arts and Sciences, and recipient of numerous prizes including the science writing prize of the American Institute of Physics for his Scientific American article on black holes.
Reviews
Susskind shines !!
This is absolutely the greatest example of what popular science book about theoretical physics/cosmology should be !! Writing is so brilliant, witty, straightforward, direct and succinct, that regardless of education level, anybody can enjoy interesting content (history of science as well as author's personal story) of "The Black Hole War". Author uses analogies in the best possible way, comparable only to Brian Greene and Michio Kaku. Drawings are frequent, well selected, informative and easy to understand. He writes: "The real tools for understanding the quantum universe are abstract mathematics: infinite dimensional Hilbert spaces, projection operators, unitary matrices and a lot of other advanced principles that take a few years to learn. But let's see how we do in just a few pages". AND HE DELIVERES !! While this book could be a starter for anybody, I recommend it to all who know Kip Thorne's famous work. For reason unknown to me, important black hole "war" is not mentioned in "Black Holes & Time Warps" at all. Professor Susskind created a true masterpiece where he even accepts coexistence of science and faith by writing: "The British intellectual world seems to be big enough for both Dawkins and Polkinghorne". Nothing but big applaud for the author and his effort !!
The history is ultimately written by the winners
Leonard Susskind is not only a co-father of string theory, the holographic principle, and many other key concepts of physics but also one of the most original physicists of our era.
He's been fighting against some superficially plausible but fundamentally wrong ideas for decades. During this ferocious fight, he had to discover many fascinating things about quantum gravity.
The battle was about the preservation of the information by black holes. Using revolutionary but approximate results, Stephen Hawking has argued since the 1970s that the information is lost after a black hole evaporates. Leonard Susskind claimed that it was preserved: this preservation, also called unitarity, is one of the postulates of quantum mechanics and these postulates are and have to be completely universal.
Susskind was right. We know many reasons why it is so, including recent results in string theory, and many of them are explained in the book. We also know loopholes that show that Hawking's old qualitative arguments are not quite correct even though his numerical results are numerically almost accurate.
It took many years for Hawking to understand and admit that the information was preserved in the full theory and that physics makes sense. During those years, Susskind was a new "Ahab" waiting for Hawking's elusive concession. However, the book offers a lot of personal stories and emotions, too. Susskind talks about several well-known names of science such as Stephen Hawking, Gerard 't Hooft, Roger Penrose, and Richard Feynman. All of them, and others, have been players in this fascinating story. [Read on...]
