What does realism about the quantum state imply? What follows when quantum theory is applied without restriction, if need be, to the whole universe? These are the questions which an illustrious team of philosophers and physicists debate in this volume. All the contributors are agreed on realism, and on the need, or the aspiration, for a theory that unites micro- and macroworlds, at least in principle. But the further claim argued by some is that if you allow the Schrödinger equation unrestricted application, supposing the quantum state to be something physically real, then this universe is one of countlessly many others, constantly branching in time, all of which are real. The result is the many worlds theory, also known as the Everett interpretation of quantum mechanics. The contrary claim sees this picture of many worlds as in no sense inherent in quantum mechanics, even when the latter is allowed unrestricted scope and even given that the quantum state itself is something physically real. For this picture of branching worlds fails to make physical sense, let alone common sense, even on its own terms. The status of these worlds, what they are made of, is never adequately explained. Ordinary ideas about time and identity over time become hopelessly compromised. The concept of probability itself is brought into question. This picture of many branching worlds is inchoate, it is a vision, an error. There are realist alternatives to many worlds, some even that preserve the Schrödinger equation unchanged. Twenty specially written essays, accompanied by commentaries and discussions, examine these claims and counterclaims in depth. They focus first on the question of ontology, the existence of worlds (Part 1 and 2), second on the interpretation of probability (Parts 3 and 4), and third on alternatives or additions to many worlds (Parts 5 and 6). The introduction offers a helpful guide to the arguments for the Everett interpretation, particularly as they have been formulated in the last two decades.

A novel interpretation of quantum mechanics, first proposed in brief form by Hugh Everett in 1957, forms the nucleus around which this book has developed. In his interpretation, Dr. Everett denies the existence of a separate classical realm and asserts the propriety of considering a state vector for the whole universe. Because this state vector never collapses, reality as a whole is rigorously deterministic. This reality, which is described jointly by the dynamical variables and the state vector, is not the reality customarily perceived; rather, it is a reality composed of many worlds. By virtue of the temporal development of the dynamical variables, the state vector decomposes naturally into orthogonal vectors, reflecting a continual splitting of the universe into a multitude of mutually unobservable but equally real worlds, in each of which every good measurement has yielded a definite result, and in most of which the familiar statistical quantum laws hold. The volume contains Dr. Everett's short paper from 1957, "'Relative State' Formulation of Quantum Mechanics," and a far longer exposition of his interpretation, entitled "The Theory of the Universal Wave Function," never before published. In addition, other papers by Wheeler, DeWitt, Graham, and Cooper and Van Vechten provide further discussion of the same theme. Together, they constitute virtually the entire world output of scholarly commentary on the Everett interpretation. Originally published in 1973. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Fun science meets humor and heart in this adventure about a boy who is searching for his mother . . . in a parallel universe. Stephen Albie Bright leads a happy, normal life. Well, as normal as it gets with two astrophysicist parents who named their son after their favorite scientists, Stephen Hawking and Albert Einstein. But then Albie’s mother dies of cancer, and his world is shattered. When his father explains that she might be alive in a parallel universe, Albie knows he has to find her. So, armed with a box, a laptop, and a banana, Albie sets out to do just that. Of course, when you’re universe-hopping for the very first time, it’s difficult to find the one you want. As Albie searches, he discovers some pretty big surprises about himself and our universe(s), and stumbles upon the answers to life’s most challenging questions. A poignant, funny, and heartwarming adventure, this extraordinary novel is for anyone who has ever been curious. Praise for The Many Worlds of Albie Bright: “A big book with a big brain, big laughs, and a big, big heart.” —FRANK COTTRELL BOYCE, New York Times bestselling author of Millions and Cosmic “Hilarious and full of heart.” —PIERS TORDAY, author of The Last Wild “I’d love this book in all the worlds. Heartbreaking, heartwarming, heartstopping. Amazing.” —HOLLY SMALE, author of the award-winning Geek Girl series “Heartwarming.” —The Guardian “Proves the theory that novels about science can be enormous fun.” —The Times Children’s Book of the Week (UK) “Moving, and exploding with scientific ideas and wonder.” —The Herald (UK)

What would it mean to apply quantum theory, without restriction and without involving any notion of measurement and state reduction, to the whole universe? What would realism about the quantum state then imply? This book brings together an illustrious team of philosophers and physicists to debate these questions. The contributors broadly agree on the need, or aspiration, for a realist theory that unites micro- and macro-worlds. But they disagree on what this implies. Some argue that if unitary quantum evolution has unrestricted application, and if the quantum state is taken to be something physically real, then this universe emerges from the quantum state as one of countless others, constantly branching in time, all of which are real. The result, they argue, is many worlds quantum theory, also known as the Everett interpretation of quantum mechanics. No other realist interpretation of unitary quantum theory has ever been found. Others argue in reply that this picture of many worlds is in no sense inherent to quantum theory, or fails to make physical sense, or is scientifically inadequate. The stuff of these worlds, what they are made of, is never adequately explained, nor are the worlds precisely defined; ordinary ideas about time and identity over time are compromised; no satisfactory role or substitute for probability can be found in many worlds theories; they can't explain experimental data; anyway, there are attractive realist alternatives to many worlds. Twenty original essays, accompanied by commentaries and discussions, examine these claims and counterclaims in depth. They consider questions of ontology - the existence of worlds; probability - whether and how probability can be related to the branching structure of the quantum state; alternatives to many worlds - whether there are one-world realist interpretations of quantum theory that leave quantum dynamics unchanged; and open questions even given many worlds, including the multiverse concept as it has arisen elsewhere in modern cosmology. A comprehensive introduction lays out the main arguments of the book, which provides a state-of-the-art guide to many worlds quantum theory and its problems.

A World of Many Worlds is a search into the possibilities that may emerge from conversations between indigenous collectives and the study of science's philosophical production. The contributors explore how divergent knowledges and practices make worlds. They work with difference and sameness, recursion, divergence, political ontology, cosmopolitics, and relations, using them as concepts, methods, and analytics to open up possibilities for a pluriverse: a cosmos composed through divergent political practices that do not need to become the same.

Peter Byrne tells the story of Hugh Everett III (1930-1982), whose "many worlds" theory of multiple universes has had a profound impact on physics and philosophy. Using Everett's unpublished papers (recently discovered in his son's basement) and dozens of interviews with his friends, colleagues, and surviving family members, Byrne paints, for the general reader, a detailed portrait of the genius who invented an astonishing way of describing our complex universe from the inside. Everett's mathematical model (called the "universal wave function") treats all possible events as "equally real", and concludes that countless copies of every person and thing exist in all possible configurations spread over an infinity of universes: many worlds. Afflicted by depression and addictions, Everett strove to bring rational order to the professional realms in which he played historically significant roles. In addition to his famous interpretation of quantum mechanics, Everett wrote a classic paper in game theory; created computer algorithms that revolutionized military operations research; and performed pioneering work in artificial intelligence for top secret government projects. He wrote the original software for targeting cities in a nuclear hot war; and he was one of the first scientists to recognize the danger of nuclear winter. As a Cold Warrior, he designed logical systems that modeled "rational" human and machine behaviors, and yet he was largely oblivious to the emotional damage his irrational personal behavior inflicted upon his family, lovers, and business partners. He died young, but left behind a fascinating record of his life, including correspondence with such philosophically inclined physicists as Niels Bohr, Norbert Wiener, and John Wheeler. These remarkable letters illuminate the long and often bitter struggle to explain the paradox of measurement at the heart of quantum physics. In recent years, Everett's solution to this mysterious problem - the existence of a universe of universes - has gained considerable traction in scientific circles, not as science fiction, but as an explanation of physical reality.

Recent discoveries in cosmology have led to a bizarre new worldview that (to paraphrase Niels Bohr) may be crazy enough to be true. Just consider the litany of mind-boggling new ideas being bandied about lately: the acceleration of cosmic expansion, dark energy (on top of dark matter, yet!), primordial "ripples" in space-time, the quantum creation of the universe from nothing, eternal cosmic inflation, multiple universes . . .Sound crazy enough for you? Fortunately, the new theoretical advances also lead to testable predictions, and we may soon witness the confirmation of some of these predictions by fresh astronomical findings. Alex Vilenkin's own scientific work has been closely tied to the emergence of the new worldview, from the original ideas to the most recent developments. In Many Worlds in One, he gives an exciting, surprisingly entertaining firsthand account of the birth of the new cosmology, and its fascinatingand at times disturbingimplications.

The national bestselling author of The God Equation takes us on a thrilling journey to explore black holes and time machines, multidimensional space and the possibility that parallel universes may lay alongside our own. “A wonderful tour, with an expert guide.” —Brian Greene, New York Times bestselling author of The Elegant Universe Kaku skillfully guides us through the latest innovations in string theory and its latest iteration, M-theory, which posits that our universe may be just one in an endless multiverse, a singular bubble floating in a sea of infinite bubble universes. If M-theory is proven correct, we may perhaps finally find answer to the question, “What happened before the big bang?” This is an exciting and unforgettable introduction into the new cutting-edge theories of physics and cosmology from one of the pre-eminent voices in the field.

In Many Worlds, renowned scientists in fields from physics to astronomy discuss the possibility of a cosmic evolutionary process that guides not only our universe, but other planets and universes as well. Physicist and author Paul Davies observes that “if it turns out to be the case that the universe is inherently bio-friendly, then the scientific, theological, and philosophical implications will be extremely significant.” Many Worlds first focuses on what lessons might be learned from the latest knowledge of the origin and evolution of life. After establishing a well-grounded relationship between science and religion, authors such as Arthur Peacocke and John Leslie evaluate the intricate configuration of events that must occur to create a dynamic and chemically enriched environment capable of not only supporting life, but evolutionary processes as well. The final section addresses the provocative question of extraterrestrial life. What we may find could drastically change our relation to the universe and our creator. As we reflect on the possibilities that the universe presents, author and contributor Christian de Duve aptly states, “Many myths have had to be abandoned. But mystery remains, more profound and beautiful than ever before, a reality almost inaccessible to our feeble human means.” Is our existence part of a divine scheme ingenuously designed to support life, or is it an extraordinary chain of accidents that culminate in a life-permitting environment? The scientific advancements of the past century cannot help but capture the imagination and inspire renewed hope for the future. This volume will add dimension and insight to these yet unanswered questions.

When Gary Jackson, a bright academic student, suffers life changing injuries in a road traffic accident, his world begins to unravel. Having taught himself to lucid dream, he now spends considerable time in bed, living out fantasies in his own mind that he could never experience in the waking world. However, when a relative with dementia claims to have witnessed a murder he committed in a dream, Gary starts to question the nature of reality, and wonders if his actions in the dream world have real life consequences. Meanwhile, in another place, Physics student Gary Jackson finds himself in prison for a murder he has no memory of committing. Can the dreamer help the student get acquitted for a murder everyone saw him commit? Or will Gary spend his life in prison for someone else's crime?
