This book was released on 2021-07-20 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: For anyone who has ever wondered about such questions as what the meaning of life is, what the purpose of their own life is, whether there is life after death, whether God exists, what the future holds for humanity, and why anything exists at all as opposed to nothingness, then this book answers all of those questions using the known laws of physics. This work details physicist and mathematician Prof. Frank J. Tipler's Omega Point cosmology, which has been published and extensively peer-reviewed in leading physics journals. The Omega Point cosmology is a proof (i.e., mathematical theorem) demonstrating that sapient life (in the form of, e.g., immortal superintelligent human-mind computer-uploads and artificial intelligences) is required by standard physics (viz., the Second Law of Thermodynamics, General Relativity, and Quantum Mechanics) to take control over all matter in the universe, for said life to eventually force the collapse of the universe, and for the computational resources of the universe (in terms of both processor speed and memory storage) to diverge to infinity as the universe collapses into a final singularity, termed the Omega Point. Said Omega Point cosmology is also an intrinsic component of the Feynman-DeWitt-Weinberg quantum gravity/Standard Model Theory of Everything (TOE) correctly describing and unifying all the forces in physics, of which TOE is itself mathematically forced by the aforementioned known physical laws. The Omega Point final singularity has all the unique properties claimed for God in the traditional religions. This book additionally addresses the societal implications of the Omega Point cosmology.

Book excerpt: ABSTRACT: Analysis is given of the Omega Point cosmology, an extensively peer-reviewed proof (i.e., mathematical theorem) published in leading physics journals by professor of physics and mathematics Frank J. Tipler, which demonstrates that in order for the known laws of physics to be mutually consistent, the universe must diverge to infinite computational power as it collapses into a final cosmological singularity, termed the Omega Point. The theorem is an intrinsic component of the Feynman–DeWitt–Weinberg quantum gravity/Standard Model Theory of Everything (TOE) describing and unifying all the forces in physics, of which itself is also required by the known physical laws. With infinite computational resources, the dead can be resurrected—never to die again—via perfect computer emulation of the multiverse from its start at the Big Bang. Miracles are also physically allowed via electroweak quantum tunneling controlled by the Omega Point cosmological singularity. The Omega Point is a different aspect of the Big Bang cosmological singularity—the first cause—and the Omega Point has all the haecceities claimed for God in the traditional religions. From this analysis, conclusions are drawn regarding the social, ethical, economic and political implications of the Omega Point cosmology.

Book excerpt: A highly respected physicist demonstrates that the essential beliefs of Christianity are wholly consistent with the laws of physics. Frank Tipler takes an exciting new approach to the age-old dispute about the relationship between science and religion in The Physics of Christianity. In reviewing centuries of writings and discussions, Tipler realized that in all the debate about science versus religion, there was no serious scientific research into central Christian claims and beliefs. So Tipler embarked on just such a scientific inquiry. The Physics of Christianity presents the fascinating results of his pioneering study. Tipler begins by outlining the basic concepts of physics for the lay reader and brings to light the underlying connections between physics and theology. In a compelling example, he illustrates how the God depicted by Jews and Christians, the Uncaused First Cause, is completely consistent with the Cosmological Singularity, an entity whose existence is required by physical law. His discussion of the scientific possibility of miracles provides an impressive, credible scientific foundation for many of Christianity’s most astonishing claims, including the Virgin Birth, the Resurrection, and the Incarnation. He even includes specific outlines for practical experiments that can help prove the validity of the “miracles” at the heart of Christianity. Tipler’s thoroughly rational approach and fully accessible style sets The Physics of Christianity apart from other books dealing with conflicts between science and religion. It will appeal not only to Christian readers, but also to anyone interested in an issue that triggers heated and divisive intellectual and cultural debates.

Available in PDF, EPUB and Kindle. Book excerpt: The author has spent his life in an obsessive quest to understand the nature of reality and the purpose of existence. Many would say this is a symptom of Asperger s syndrome, a high functioning form of autism. While I certainly fit this profile I believe there is a different more amazing reason. If an individual actualizes their potential in this space-time it is also actualized in the Singularity the space-less, time-less part of the dual universe at the quantum level. Each step of my life has led to find the answers because in the Singularity I had already found them. Here are the answers to God, the universe, and everything, I give them to you now because you are in desperate need of them, do with them what you will. Buy the book or not, read the book or not, I do not care, for I have completed my task and fulfilled my destiny, and that is all that matters. But if you do read the book be prepared for a remarkable vision of the nature of reality, and a magnificent purpose of existence illustrated with poetry and painting.

Quantum Gravity was his goal and remained his goal throughout his lifetime until the very end. The pursuit of Quantum Gravity requires a profound understanding of Quantum Physics and Gravitation Physics. As G. A. Vilkovisky commented , "Quantum Gravity is a combination of two words, and one should know both. Bryce understood this as nobody else, and this wisdom is completely unknown to many authors of the flux of papers that we see nowadays." Distingished physicist Cecile DeWitt-Morette skillfully blends her personal and scientific account with a wealth of her late husband's often unpublished writings on the subject matter. This volume, through the perspective of the leading researcher on quantum gravity of his generation, will provide an invaluable source of reference for anyone working in the field.

Book excerpt: #1 NEW YORK TIMES BESTSELLER • The epic story of the greatest quest in all of science—the holy grail of physics that would explain the creation of the universe—from renowned theoretical physicist and author of The Future of the Mind and The Future of Humanity When Newton discovered the law of gravity, he unified the rules governing the heavens and the Earth. Since then, physicists have been placing new forces into ever-grander theories. But perhaps the ultimate challenge is achieving a monumental synthesis of the two remaining theories—relativity and the quantum theory. This would be the crowning achievement of science, a profound merging of all the forces of nature into one beautiful, magnificent equation to unlock the deepest mysteries in science: What happened before the Big Bang? What lies on the other side of a black hole? Are there other universes and dimensions? Is time travel possible? Why are we here? Kaku also explains the intense controversy swirling around this theory, with Nobel laureates taking opposite sides on this vital question. It is a captivating, gripping story; what’s at stake is nothing less than our conception of the universe. Written with Kaku’s trademark enthusiasm and clarity, this epic and engaging journey is the story of The God Equation.

Available in PDF, EPUB and Kindle. Book excerpt: Quantum gravity is perhaps the most important open problem in fundamental physics. It is the problem of merging quantum mechanics and general relativity, the two great conceptual revolutions in the physics of the twentieth century. The loop and spinfoam approach, presented in this 2004 book, is one of the leading research programs in the field. The first part of the book discusses the reformulation of the basis of classical and quantum Hamiltonian physics required by general relativity. The second part covers the basic technical research directions. Appendices include a detailed history of the subject of quantum gravity, hard-to-find mathematical material, and a discussion of some philosophical issues raised by the subject. This fascinating text is ideal for graduate students entering the field, as well as researchers already working in quantum gravity. It will also appeal to philosophers and other scholars interested in the nature of space and time.

Book excerpt: Quantum physics is the most fundamental -- but also the most baffling -- branch of science. Allowing for dead-and-alive cats, teleportation, antimatter, and parallel universes, as well as underpinning all of our digital technology, it's as important as it is mind-bending. This clear and compact book demystifies the strange and beautiful quantum world, and hence the nature of reality itself. Contents include: Schrodinger's cat, inside the atom, the particle zoo, the Higgs boson, Heisenberg's uncertainty principle, God playing dice, relativity, the Big Bang, dark energy and matter, black holes, the fate of the Universe, the Theory of Everything, quantum gravity, string theory, the multiverse, instant communication, quantum computing and cryptography, superconductivity, quantum biology, quantum consciousness, and much more. Written as a series of mini essays with 200 simple diagrams to help understanding, there can be no easier guide to this notoriously confusing subject. At last it's possible for non-specialists to understand quantum theory and its central role in the birth of the universe and the very existence of life.

Available in PDF, EPUB and Kindle. Book excerpt: 'An astonishingly good read, gripping and thought-provoking' William Lane Craig 'If you wanted to understand Stephen Hawking but couldn't face the maths, this is the book for you.' Dr Althea Wilkinson, Jodrell Bank Stephen Hawking kept breaking rules. Given two years to live, he managed another 54. He wrote about quantum cosmology - and sold 20 million books. He could not speak, yet the world recognized his voice. Hutchings and Wilkinson shine light on his extraordinary ideas. The result is a thought-provoking theological commentary and critique of black holes, origins, many universes, and Big Questions. In 'God, Stephen Hawking and the Multiverse', Hutchings and Wilkinson explain the key elements of Stephen Hawking's physical and mathematical theories, consider their philosophical and religious implications, and relate his ideas to traditional Judaeo-Christian concepts of God. This book about Stephen Hawking and God and the relationship between God and science gives a brief but engaging overview of the history of physics and cosmology. Perfect for beginners, 'God, Stephen Hawking and the Multiverse' offers a concise and accessible introduction to Hawking's work and how his contributions to modern physics and cosmology can complement religion. Exploring topics such as gravity, quantum mechanics and general relativity, the authors offer a fresh perspective on the relationship between God and science, providing a balanced and informed commentary on Hawking's work both scientifically and theologically.

Available in PDF, EPUB and Kindle. Book excerpt: Quantum gravity is the name given to a theory that unites general relativity - Einstein's theory of gravitation and spacetime - with quantum field theory, our framework for describing non-gravitational forces. The Structural Foundations of Quantum Gravity brings together philosophers and physicists to discuss a range of conceptual issues that surface in the effort to unite these theories, focusing in particular on the ontological nature of the spacetime that results. Although there has been a great deal written about quantum gravity from the perspective of physicists and mathematicians, very little attention has been paid to the philosophical aspects. This volume closes that gap, with essays written by some of the leading researchers in the field. Individual papers defend or attack a structuralist perspective on the fundamental ontologies of our physical theories, which offers the possibility of shedding new light on a number of foundational problems. It is a book that will be of interest not only to physicists and philosophers of physics but to anyone concerned with foundational issues and curious to explore new directions in our understanding of spacetime and quantum physics.

Book excerpt: This book provides insight into major facets of the physics of quantum gravity. The application of quantum field theory for explaining gravity is one of the main problems in contemporary elementary Physics. It has been in existence for nearly a century, but a definite answer is yet to be determined. Loop quantum gravity and string theory have answered several answers associated with this problem, but they have brought with themselves a huge set of added questions. Apart from these two theories, several other alternative theories have also been developed over the decades. Renowned authors from across the globe have contributed in this book. The content provided in this book deals with gravity and its quantization through known and alternative methods in order to provide a better understanding on the quantum nature of gravity. Readers will find an extensive compilation of physical and mathematical concepts along with updated research regarding the challenging puzzle of quantum gravity in this book.

Available in PDF, EPUB and Kindle. Book excerpt: The forty papers collected here honor one of the great scientists of our time--John Archibald Wheeler. In this volume are gathered the six issues of the journal Foundations of Physics (February through July 1986) that celebrate his seventy-fifth birthday. Enlivened by Professor Wheeler's celebrated drawings, the book captures and illuminates his many contributions to physics, including his discovery of the scattering matrix and his elucidation, with Niels Bohr, of the mechanism of nuclear fission, his many contributions to Einstein's theory of gravity (for instance, the black hole), his deep insights into quantum theory and measurement (the elementary quantum phenomenon), and his efforts to explain the origins of the quantum postulate and quantum gravity (the meaning circuit and the Wheeler-DeWitt Equation). The majority of the papers reflect and build on Professor Wheeler's revolutionary ideas. Many scientists are convinced that his insights into the foundation of modern-day physics will induce a profound change in our perception of the universe. This book will appeal to scientists and philosophers who wish to look at one man's rendering of the "big picture" through the eyes of his colleagues. The work is prefaced by a compilation of quotes from Professor Wheeler, edited by Kip S. Thorne and Wojciech Zurek. The contributors to Between Quantum and Cosmos are M. Alexander, A. Anderson, H. H. Barschall, J. D. Bekenstein, C. H. Bennett, P. G. Bergmann, V. B. Braginsky, D. R. Brill, L. Brown, I. Ciufolini, L. Cohen, M. Demianski, D. Deutsch, B. DeWitt, C. DeWitt-Morette, R. H.

Available in PDF, EPUB and Kindle. Book excerpt: Theoretical physics and foundations of physics have not made much progress in the last few decades. Whether we are talking about unifying general relativity and quantum field theory (quantum gravity), explaining so-called dark energy and dark matter (cosmology), or the interpretation and implications of quantum mechanics and relativity, there is no consensus in sight. In addition, both enterprises are deeply puzzled about various facets of time including above all, time as experienced. The authors argue that, across the board, this impasse is the result of the "dynamical universe paradigm," the idea that reality is fundamentally made up of physical entities that evolve in time from some initial state according to dynamical laws. Thus, in the dynamical universe, the initial conditions plus the dynamical laws explain everything else going exclusively forward in time. In cosmology, for example, the initial conditions reside in the Big Bang and the dynamical law is supplied by general relativity. Accordingly, the present state of the universe is explained exclusively by its past. This book offers a completely new paradigm (called Relational Blockworld), whereby the past, present and future co-determine each other via "adynamical global constraints," such as the least action principle. Accordingly, the future is just as important for explaining the present as is the past. Most of the book is devoted to showing how Relational Blockworld resolves many of the current conundrums of both theoretical physics and foundations of physics, including the mystery of time as experienced and how that experience relates to the block universe.

Available in PDF, EPUB and Kindle. Book excerpt: Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behaviour of matter in a curved spacetime. This theory is the basis for the standard model of big bang cosmology. The discovery of gravitational waves at the LIGO observatory in the US (and then Virgo, in Italy) is only the most recent of this theory's many triumphs. The second is quantum mechanics. This theory describes the properties and behaviour of matter and radiation at their smallest scales. It is the basis for the standard model of particle physics, which builds up all the visible constituents of the universe out of collections of quarks, electrons and force-carrying particles such as photons. The discovery of the Higgs boson at CERN in Geneva is only the most recent of this theory's many triumphs. But, while they are both highly successful, these two structures leave a lot of important questions unanswered. They are also based on two different interpretations of space and time, and are therefore fundamentally incompatible. We have two descriptions but, as far as we know, we've only ever had one universe. What we need is a quantum theory of gravity. Approaches to formulating such a theory have primarily followed two paths. One leads to String Theory, which has for long been fashionable, and about which much has been written. But String Theory has become mired in problems. In this book, Jim Baggott describes "the road less travelled": an approach which takes relativity as its starting point, and leads to a structure called Loop Quantum Gravity. Baggott tells the story through the careers and pioneering work of two of the theory's most prominent contributors, Lee Smolin and Carlo Rovelli. Combining clear discussions of both quantum theory and general relativity, this book offers one of the first efforts to explain the new quantum theory of space and time.
