Over the last decade the physics of black holes has been revolutionized by developments that grew out of Jacob Bekenstein's realization that black holes have entropy. Stephen Hawking raised profound issues concerning the loss of information in black hole evaporation and the consistency of quantum mechanics in a world with gravity. For two decades these questions puzzled theoretical physicists and eventually led to a revolution in the way we think about space, time, matter and information. This revolution has culminated in a remarkable principle called “The Holographic Principle”, which is now a major focus of attention in gravitational research, quantum field theory and elementary particle physics. Leonard Susskind, one of the co-inventors of the Holographic Principle as well as one of the founders of String theory, develops and explains these concepts.

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.

These three lectures cover a certain aspect of complexity and black holes, namely the relation to the second law of thermodynamics. The first lecture describes the meaning of quantum complexity, the analogy between entropy and complexity, and the second law of complexity. Lecture two reviews the connection between the second law of complexity and the interior of black holes. Prof. L. Susskind discusses how firewalls are related to periods of non-increasing complexity which typically only occur after an exponentially long time. The final lecture is about the thermodynamics of complexity, and “uncomplexity” as a resource for doing computational work. The author explains the remarkable power of “one clean qubit,” in both computational terms and in space-time terms. This book is intended for graduate students and researchers who want to take the first steps towards the mysteries of black holes and their complexity.

Based on lectures given in honour of Stephen Hawking's sixtieth birthday, this book comprises contributions from some of the world's leading theoretical physicists. It begins with a section containing chapters by successful scientific popularisers, bringing to life both Hawking's work and other exciting developments in physics. The book then goes on to provide a critical evaluation of advanced subjects in modern cosmology and theoretical physics. Topics covered include the origin of the universe, warped spacetime, cosmological singularities, quantum gravity, black holes, string theory, quantum cosmology and inflation. As well as providing a fascinating overview of the wide variety of subject areas to which Stephen Hawking has contributed, this book represents an important assessment of prospects for the future of fundamental physics and cosmology.

Through reading this book, you will have a better understanding on the Holographic Universe and your ability to have experiences in the Holographic Universe increases. Through keeping an open, clear mind (as you read), you can experience what the author has experienced and you will be able to understand what the author is explaining. Instead of just reading the words, read it with the intent to understand the depths of what is being explained. Keep contemplating on it until you experience and understand what is being said about the Holographic Universe. Keep reading the book again and again until you have understood it so that your ability to have experiences in the Holographic Universe increases. In this book, the explanations on the Holographic Universe are based on: 1. the guidance from God, 2. the knowledge of the Brahma Kumaris, 3. Quantum Mechanics (nothing in this book is contrary to quantum mechanics), 4. research, 5. experiences of the author, 6. the knowledge on the chakras and aura, 7. the ancient Hindu texts, etc. There are explanations, in this book, about: 1. the various divisions and nature of the Holographic Universe. 2. how everything happens as per the World Drama (Akashic Records). 3. how people live in two kinds of worlds, the Real World and the Holographic World, at the same time. 4. the Holographic Film of the Hologram which we are participating in. 5. how various kinds of worlds exist. 6. how the quantum energies materialise the physical bodies and physical world through the Holographic Universe. 7. how the creation process takes place through the vortices and chakras. 8. Near Death Experiences 9. the Cosmic Consciousness. 10. how subtle dimensions, holographic bodies and subtle bodies are created. 11. how the aura is used during experiences. 12. how quantum energies of different densities materialise a different kind of Real World for us to live in. 13. how the Holographic Universe changes when the world transforms. 14. the meditation and knowledge of the Brahma Kumaris.
