DOWNLOAD EBOOKThe book collects a series of articles to review the advances that have been made in the field of gravitational collapse in general relativity and alternative theories of gravity in the past few years. Many approaches to black hole and singularity formation in general relativity and beyond have been proposed over the last few decades. The importance of collapse models is that they provide natural thought experiments where to test the behavior and properties of a variety of approaches to general relativity and its implications for ultra-compact objects in the universe.

Modified and Quantum Gravity

ISBN-13: 3031315200
DOWNLOAD EBOOKThis book discusses theoretical predictions and their comparison with experiments of extended and modified classical and quantum theories of gravity. The goal is to provide a readable access and broad overview over different approaches to the topic to graduate and PhD students as well as to young researchers. The book presents both, theoretical and experimental insights and is structured in three parts. The first addresses the theoretical models beyond special and general relativity such as string theory, Poincare gauge theory and teleparallelism as well as Finsler gravity. In turn, the second part is focused on the observational effects that these models generate, accounting for tests and comparisons which can be made on all possible scales: from the universe as a whole via binary systems, stars, black holes, satellite experiments, down to laboratory experiments at micrometer and smaller scales. The last part of this book is dedicated to quantum systems and gravity, showing tests of classical gravity with quantum systems, and coupling of quantum matter and gravity.
The New Time Travelers: A Journey to the Frontiers of Physics

DOWNLOAD EBOOKThe story of physicists' quest to answer a mind-boggling question: How can we travel through time? Since H. G. Wells' 1895 classic The Time Machine, readers of science fiction have puzzled over the paradoxes of time travel. What would happen if a time traveler tried to change history? Would some force or law of nature prevent him? Or would his action produce a "new" history, branching away from the original?In the last decade of the twentieth century a group of theoretical physicists at the California Institute of Technology undertook a serious investigation of the possibility of pastward time travel, inspiring a serious and sustained study that engaged more than thirty physicists working at universities and institutes around the world.Many of the figures involved are familiar: Einstein, Stephen Hawking and Kip Thorne; others are names known mostly to physicists. These are the new time travelers, and this is the story of their work--a profoundly human endeavor marked by advances, retreats, and no small share of surprises. It is a fantastic journey to the frontiers of physics. Some images in the ebook are not displayed owing to permissions issues.
New Ideas Concerning Black Holes and the Universe

ISBN-13: 1839685417
DOWNLOAD EBOOKThe ideas presented in this book are new scientific theories based largely upon a spate of very recent astronomical observations. These theories include: a cosmological model that appears to be superior, in many respects, to the inflationary "concordance model"; proposed thermal stability criteria for a generic quantum black hole; theoretical constraints concerning black hole binary graviton emissions; theoretical effects of abelian vortices on space-time; and a proposed solution to the mystery of the observed asymmetry between universal matter and antimatter. The new ideas presented in this book have been selected in order to inspire others that, regardless of the impending limits of observation, the scientific creative process will continue.

ISBN-13: 3642419925
DOWNLOAD EBOOKThe Springer Handbook of Spacetime is dedicated to the ground-breaking paradigm shifts embodied in the two relativity theories, and describes in detail the profound reshaping of physical sciences they ushered in. It includes in a single volume chapters on foundations, on the underlying mathematics, on physical and astrophysical implications, experimental evidence and cosmological predictions, as well as chapters on efforts to unify general relativity and quantum physics. The Handbook can be used as a desk reference by researchers in a wide variety of fields, not only by specialists in relativity but also by researchers in related areas that either grew out of, or are deeply influenced by, the two relativity theories: cosmology, astronomy and astrophysics, high energy physics, quantum field theory, mathematics, and philosophy of science. It should also serve as a valuable resource for graduate students and young researchers entering these areas, and for instructors who teach courses on these subjects. The Handbook is divided into six parts. Part A: Introduction to Spacetime Structure. Part B: Foundational Issues. Part C: Spacetime Structure and Mathematics. Part D: Confronting Relativity theories with observations. Part E: General relativity and the universe. Part F: Spacetime beyond Einstein.

Gravitational Collapse and Spacetime Singularities

DOWNLOAD EBOOKPhysical phenomena in astrophysics and cosmology involve gravitational collapse in a fundamental way. The final fate of a massive star when it collapses under its own gravity at the end of its life cycle is one of the most important questions in gravitation theory and relativistic astrophysics, and is the foundation of black hole physics. General relativity predicts that continual gravitational collapse gives rise to a space-time singularity. Quantum gravity may take over in such regimes to resolve the classical space-time singularity. This book, first published in 2007, investigates these issues, and shows how the visible ultra-dense regions arise naturally and generically as an outcome of dynamical gravitational collapse. It will be of interest to graduate students and academic researchers in gravitation physics, fundamental physics, astrophysics, and cosmology. It includes a detailed review of research into gravitational collapse, and several examples of collapse models are investigated in detail.

DOWNLOAD EBOOKThis compilation based upon recent peer-reviewed journal publications encapsulates how the Flat Space Cosmology model (FSC) has become the primary competitor to the inflationary standard model of cosmology. New ideas concerning black holes, dark energy and dark matter are presented and shown to correlate extremely well with astronomical observations. Anyone who follows the fast-changing science of cosmology, has an interest in the latest developments, and would like to know how it is that our universe appears to follow equations one would ordinarily expect for a time-reversed black hole (!), may find this book to be fascinating. Cosmology is the study of how the universe has changed over the great span of time (roughly 14 billion years). Later centuries will look back upon the period from 1990-2030 as a ‘Golden Age’ of theoretical and observational cosmology. It is highly likely that we are on the verge of a deeper understanding of the most mysterious energy (‘dark energy’) and matter (‘dark matter’) comprising the majority of energy and matter in the universe. Some of the material presented in this book is on the cutting edge of dark energy and dark matter theoretical work. This book summarizes, for the first time, the groundbreaking publications of two cosmologists, one from the United States and the other from India, from 2015 thru 2020. During this highly productive period, the authors stealthily published their papers in six different peer-reviewed scientific journals, so that the model could be quietly explored in all aspects before bringing it all together in a single book. This is that book!
