Book excerpt: Although gravity is the dominant force of nature at large distances (from intermediate scales to the Hubble length), it is the weakest of forces in particle physics, though it is believed to become important again at very short scales (the Planck length). The conditions created in particle accelerators are similar to those at the time of the early

This book was released on 2006-04-11 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jean-Pierre Vigier continually labeled one of les heretiques de la science, l’eternel resistant et le patriarche is yet a pillar of modern physics and mathematics, with one leg firmly planted in theory and the other in empiricism spanning a career of nearly 60 years with a publication vitae quickly approaching 400! He wrote of his mentor Louis de Broglie “Great physicists fight great battles”, which perhaps applies even more so to 1 Jean-Pierre Vigier himself . If fortune allows a visit to Paris, reported to be the city of love, and certainly one of the most beautiful and interesting cities in the world; one has been treated to a visual and cultural feast. For example a leisurely stroll from the Musee du Louvre along the Champs-Elysees to the Arc de Triomphe would instill even the least creative soul with the entelechies of a poets muse. It is perhaps open to theoretical interpretation, but if causal conditions have allowed one to be a physicist, visiting Paris, one may have taken opportunity to visit the portion of the old Latin quarter in place Jussieu where Pierre et Marie Curie Universite, reported to be ‘the best university in France’, is stationed.
Download or read book Inflationary Cosmology written by L. F. Abbott and published by World Scientific. This book was released on 1986 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inflation has revolutionized cosmology primarily because it has eliminated the dependence of cosmological modelling on initial conditions. Thus inflationary cosmology is able to account for the present universe starting from a wide range of initial conditions. This volume reviews the presents state of subject. Each chapter consists of a brief introduction followed by reprints of important papers. Experts in the field are also provided with a unifying view point.
Download or read book Primordial Cosmology written by Giovanni Montani and published by World Scientific. This book was released on 2011 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primordial Cosmology deals with one of the most puzzling and fascinating topics debated in modern physics - the nature of the Big Bang singularity. The authors provide a self-consistent and complete treatment of the very early Universe dynamics, passing through a concise discussion of the Standard Cosmological Model, a precise characterization of the role played by the theory of inflation, up to a detailed analysis of the anisotropic and inhomogeneous cosmological models. The most peculiar feature of this book is its uniqueness in treating advanced topics of quantum cosmology with a well-traced link to more canonical and pedagogical notions of fundamental cosmology. This book traces clearly the backward temporal evolution of the Universe, starting with the Robertsonndash;Walker geometry and ending with the recent results of loop quantum cosmology in view of the Big Bounce. The reader is accompanied in this journey by an initial technical presentation which, thanks to the fundamental tools given earlier in the book, never seems heavy or obscure.
Download or read book Cosmogonical Processes written by William David Arnett and published by VSP. This book was released on 1986 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cosmogony deals with no less than the genesis and development of the universe, the solar system and the earth. This book was developed from a symposium in honour of Prof. A.G.W. Cameron of Harvard University on his 60th birthday, and suitably reflects his broad and influential interests. Appropriate to this perspective, a wide variety of topics are reviewed by internationally recognized experts. Beginning with cosmology and the question of dark matter, the spotlight moves to galaxy formation and then evolution. This is followed by the topic of the production of atomic nuclei in supernovae, the clues for nucleosynthesis from isotopic anomalies, and the age of the universe from nuclear chronology. Next come supernovae and neutron stars and their exotic behaviour, then molecular clouds, star formation and the primitive solar nebula. Topics of giant protoplanets, planet formation, and comets close the discussion. A short essay by Cameron provides a fascinating personal insight into the development of some of the most interesting new interdisciplinary areas of modern science. Of particular interest in his narrative is the interplay of theory, observation, experiment and computer simulation, as seen by an active participant.
Download or read book The Universe Before the Big Bang written by Maurizio Gasperini and published by Springer Science & Business Media. This book was released on 2008-10-08 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Terms such as "expanding Universe", "big bang", and "initial singularity", are nowadays part of our common language. The idea that the Universe we observe today originated from an enormous explosion (big bang) is now well known and widely accepted, at all levels, in modern popular culture. But what happens to the Universe before the big bang? And would it make any sense at all to ask such a question? In fact, recent progress in theoretical physics, and in particular in String Theory, suggests answers to the above questions, providing us with mathematical tools able in principle to reconstruct the history of the Universe even for times before the big bang. In the emerging cosmological scenario the Universe, at the epoch of the big bang, instead of being a "new born baby" was actually a rather "aged" creature in the middle of its possibly infinitely enduring evolution. The aim of this book is to convey this picture in non-technical language accessibile also to non-specialists. The author, himself a leading cosmologist, draws attention to ongoing and future observations that might reveal relics of an era before the big bang.
Download or read book Soaring on the Wings of Genius A Chronic written by Andrew Worsley and published by Universal-Publishers. This book was released on 2006-12 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is there a unifying solution to myriad physical laws of Nature that govern the Universe? String theory represents the closest yet to such a unifying solution. However, after 20 years string theory has been unable to predict the physical constants of Nature and still has not provided the answer to quantum gravity. Recent strong evidence for the presence of a newly discovered energy, which affects the entire Universe may be the first clue to an as yet unlocked scientific paradigm. Dr Worsley argues forcibly that the answer to this paradigm opens a new window on the truly unified nature of the Universe. The arguments presented are clear concise and compelling.
Download or read book Gravity Strings and Particles written by Maurizio Gasperini and published by Springer. This book was released on 2014-05-12 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: New fundamental forces of Nature? New forms of "dark'' energy? Signals from epochs preceding the Big Bang? Is our space-time unique? Only a joint study of the three topics examined in this book – gravity, strings and particles – may provide answers to these questions. Such a study may also provide the key to solving one of the most fascinating mysteries of modern science, namely: Besides time and the three spatial dimensions, how many other dimensions exist in our universe? The book is primarily addressed to readers who do not necessarily have a specific background in physics but are nevertheless interested in discovering the originality and the possible implications of some of the amazing ideas in modern theoretical physics. The emphasis is on conveying ideas rather than explaining formulas, focusing not on what is known but -- mainly -- on what is still unknown. Many parts of the book are devoted to fundamental theoretical models and results which are potentially highly relevant for a deeper understanding of Nature, but are still waiting to be confirmed (or disproved) by experiments. From this point of view, the material of this book may also be of interest to professional physicists, whether or not they work in the field of fundamental interactions.
Download or read book The Problem of Time written by Edward Anderson and published by Springer. This book was released on 2017-09-18 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a treatise on time and on background independence in physics. It first considers how time is conceived of in each accepted paradigm of physics: Newtonian, special relativity, quantum mechanics (QM) and general relativity (GR). Substantial differences are moreover uncovered between what is meant by time in QM and in GR. These differences jointly source the Problem of Time: Nine interlinked facets which arise upon attempting concurrent treatment of the QM and GR paradigms, as is required in particular for a background independent theory of quantum gravity. A sizeable proportion of current quantum gravity programs - e.g. geometrodynamical and loop quantum gravity approaches to quantum GR, quantum cosmology, supergravity and M-theory - are background independent in this sense. This book's foundational topic is thus furthermore of practical relevance in the ongoing development of quantum gravity programs. This book shows moreover that eight of the nine facets of the Problem of Time already occur upon entertaining background independence in classical (rather than quantum) physics. By this development, and interpreting shape theory as modelling background independence, this book further establishes background independence as a field of study. Background independent mechanics, as well as minisuperspace (spatially homogeneous) models of GR and perturbations thereabout are used to illustrate these points. As hitherto formulated, the different facets of the Problem of Time greatly interfere with each others' attempted resolutions. This book explains how, none the less, a local resolution of the Problem of Time can be arrived at after various reconceptualizations of the facets and reformulations of their mathematical implementation. Self-contained appendices on mathematical methods for basic and foundational quantum gravity are included. Finally, this book outlines how supergravity is refreshingly different from GR as a realization of background independence, and what background independence entails at the topological level and beyond.
Download or read book Springer Handbook of Spacetime written by Abhay Ashtekar and published by Springer. This book was released on 2014-09-01 with total page 883 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 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.
Download or read book Primordial Cosmology written by Patrick Peter and published by Oxford University Press. This book was released on 2013-02-14 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an extensive survey of all the physics necessary to understand the current developments in the field of fundamental cosmology, as well as an overview of the observational data and methods. It will help students to get into research by providing definitions and main techniques and ideas discussed today. The book is divided into three parts. Part 1 summarises the fundamentals in theoretical physics needed in cosmology (general relativity, field theory, particle physics). Part 2 describes the standard model of cosmology and includes cosmological solutions of Einstein equations, the hot big bang model, cosmological perturbation theory, cosmic microwave background anisotropies, lensing and evidence for dark matter, and inflation. Part 3 describes extensions of this model and opens up current research in the field: scalar-tensor theories, supersymmetry, the cosmological constant problem and acceleration of the universe, topology of the universe, grand unification and baryogenesis, topological defects and phase transitions, string inspired cosmology including branes and the latest developments. The book provides details of all derivations and leads the student up to the level of research articles.
Download or read book Quantum Gravity and Quantum Cosmology written by Gianluca Calcagni and published by Springer. This book was released on 2012-10-31 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum gravity has developed into a fast-growing subject in physics and it is expected that probing the high-energy and high-curvature regimes of gravitating systems will shed some light on how to eventually achieve an ultraviolet complete quantum theory of gravity. Such a theory would provide the much needed information about fundamental problems of classical gravity, such as the initial big-bang singularity, the cosmological constant problem, Planck scale physics and the early-time inflationary evolution of our Universe. While in the first part of this book concepts of quantum gravity are introduced and approached from different angles, the second part discusses these theories in connection with cosmological models and observations, thereby exploring which types of signatures of modern and mathematically rigorous frameworks can be detected by experiments. The third and final part briefly reviews the observational status of dark matter and dark energy, and introduces alternative cosmological models. Edited and authored by leading researchers in the field and cast into the form of a multi-author textbook at postgraduate level, this volume will be of benefit to all postgraduate students and newcomers from neighboring disciplines wishing to find a comprehensive guide for their future research.

Download or read book Relic Gravitons written by Massimo Giovannini and published by World Scientific. This book was released on 2024-02-27 with total page 827 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relic Gravitons delves into the cosmic backgrounds of stochastic gravitational waves, exploring their potential as a unique source of information on the early physical conditions of the Universe close to the Planck epoch. Drawing on various lecture notes, articles, and reviews since the early 1990s, the monograph presents a topical account of the subject. The aim is to offer students and practitioners a useful tool for understanding the most recent developments of a lively field that is now thriving also thanks to forthcoming observational data.While the detection of diffuse backgrounds of gravitational radiation might improve current bounds on the supplementary polarizations of gravitational waves, the author explores across the sixteen chapters of the monograph the sensitivity of cosmic gravitons to the new physics beyond the standard lore of fundamental interactions. It is argued that the discovery of relic gravitons may trigger a paradigm shift whose implications are yet to be fully understood.In different respects, the physics of relic gravitons bridges the microworld of the standard model of fundamental interactions with the macroworld of gravity and cosmology. The ultimate purpose of this book is then to provide, at once, a systematic and self-contained presentation which is still sorely lacking in the current literature.
