It successfully bridges the gap between undergraduate and advanced graduate texts by discussing topics of current research, starting from first principles. Throughout this authoritative volume, emphasis is given to the simplest, most intuitive explanation for key equations used by researchers. The first third of the book carefully develops the necessary background in general relativity and quantum fields. The rest of the book then provides self-contained accounts of all the key topics in contemporary cosmology, including inflation, topological defects, gravitational lensing, galaxy formation, large-scale structure and the distance scale. To aid understanding, the book is well illustrated with helpful figures and includes outline solutions to nearly 100 problems. All necessary astronomical jargon is clearly explained, ensuring the book is self-contained for any student with undergraduate physics.

Cosmological Probes of Light Relics (Springer Theses)

by Benjamin Wallisch

The wealth of recent cosmic microwave background and large-scale structure data has transformed the field of cosmology. These observations have not only become precise enough to answer questions about the universe on the largest scales, but also to address puzzles in the microscopic description of Nature. This thesis investigates new ways of probing the early universe, the properties of neutrinos and the possible existence of other light particles. In particular, based on detailed theoretical insights and novel analyses, new evidence for the cosmic neutrino background is found in the distribution of galaxies and in cosmic microwave background data. This tests the Standard Model of particle physics and the universe back to a time when it was about one second old. Furthermore, it is demonstrated that future observations will be capable of probing physics beyond the Standard Model since they can achieve a particular target which would either allow the detection of any light particles that have ever been in thermal equilibrium or imply strong bounds on their properties.

Cosmological Theories of Value: Science, Philosophy, and Meaning in Cosmic Evolution (Space and Society)

by Mark Lupisella

Building from foundations of modern science and cosmic evolution, as well as psychological and philosophical perspectives of value and meaning, this book explores some of humanity’s biggest questions: · Is the Universe “about something”? · What might be roles for life and intelligence in cosmic evolution? · How might we think about value, meaning, purpose, and ethics in a cosmic evolutionary context? The author explores how the sciences of relativity and quantum theory, combined with cosmic evolution and philosophical traditions such as process philosophy, contribute to the development of a broad “relationalist framework”. That framework helps inform perspectives such as “scientific minimalism” and “cosmological theories of value”. Cosmological Reverence, Cosmocultural Evolution, and the Connection-Action Principle are explored as examples of cosmological theories of value, all of which help inform how we might think about ethics, value, and meaning in a cosmic context – including application to the search for extraterrestrial life and the future of intelligence in the universe. This book will benefit a diverse range of practitioners in philosophy, science, and policy, including interdisciplinary fields such as Science and Society and cultural evolution studies. From the Foreword: “This volume ranges from the sciences of cosmic evolution, relativity, and quantum mechanics, to value theory and process philosophy, all with the goal of exploring how they relate to humanity in the sense of worldviews and meaning. With his three cosmological theories of value, Lupisella goes beyond the bounds of most books on naturalism, and into fundamental questions about the nature of the universe and our relation to it. To read Lupisella is to have a mind-boggling experience, to want to race to references, to want to know more.” Steven J. Dick Former Baruch S.

Cosmological and Black Hole Apparent Horizons (Lecture Notes in Physics #907)

by Valerio Faraoni

This book overviews the extensive literature on apparent cosmological and black hole horizons. In theoretical gravity, dynamical situations such as gravitational collapse, black hole evaporation, and black holes interacting with non-trivial environments, as well as the attempts to model gravitational waves occurring in highly dynamical astrophysical processes, require that the concept of event horizon be generalized. Inequivalent notions of horizon abound in the technical literature and are discussed in this manuscript. The book begins with a quick review of basic material in the first one and a half chapters, establishing a unified notation. Chapter 2 reminds the reader of the basic tools used in the analysis of horizons and reviews the various definitions of horizons appearing in the literature. Cosmological horizons are the playground in which one should take baby steps in understanding horizon physics. Chapter 3 analyzes cosmological horizons, their proposed thermodynamics, and several coordinate systems. The remaining chapters discuss analytical solutions of the field equations of General Relativity, scalar-tensor, and f(R) gravity which exhibit time-varying apparent horizons and horizons which appear and/or disappear in pairs. An extensive bibliography enriches the volume. The intended audience is master and PhD level students and researchers in theoretical physics with knowledge of standard gravity.

Cosmological and Psychological Time (Boston Studies in the Philosophy and History of Science #285)

by Yuval Dolev Michael Roubach

This book examines the many faces of philosophy of time, including the metaphysical aspects, natural science issues, and the consciousness of time. It brings together the different methodologies of investigating the philosophy of time. It does so to counter the growing fragmentation of the field with regard to discussions, and the existing cleavage between analytic and continental traditions in philosophy. The book's multidirectional approach to the notion of time contributes to a better understanding of time's metaphysical, physical and phenomenological aspects. It helps clarify the presuppositions underpinning the analytic and continental traditions in the philosophy of time and offers ways in which the differences between them can be bridged.

Cosmology (Series in Astronomy and Astrophysics)

by Nicola Vittorio

Modern cosmology has changed significantly over the years, from the discovery to the precision measurement era. The data now available provide a wealth of information, mostly consistent with a model where dark matter and dark energy are in a rough proportion of 3:7. The time is right for a fresh new textbook which captures the state-of-the art in cosmology. Written by one of the world's leading cosmologists, this brand new, thoroughly class-tested textbook provides graduate and undergraduate students with coverage of the very latest developments and experimental results in the field. Prof. Nicola Vittorio shows what is meant by precision cosmology, from both theoretical and observational perspectives. This book is divided into three main parts: Part I provides a pedagogical, but rigorous, general relativity-based discussion of cosmological models, showing the evidence for dark energy, the constraints from primordial nucleosynthesis and the need for inflation Part II introduces density fluctuations and their statistical description, discussing different theoretical scenarios, such as CDM, as well as observations Part III introduces the general relativity approach to structure formation and discusses the physics behind the CMB temperature and polarization pattern of the microwave sky Carefully adapted from the course taught by Prof. Vittorio at the University of Rome Tor Vergata, this book will be an ideal companion for advanced students undertaking a course in cosmology. Features: Incorporates the latest experimental results, at a time of rapid change in this field, with balanced coverage of both theoretical and experimental perspectives Each chapter is accompanied by problems, with detailed solutions The basics of tensor calculus and GR are given in the appendices

Cosmology Beyond Einstein

by Adam Ross Solomon

This work investigates the theoretical and cosmological implications of modifying Einstein's theory of general relativity. It explores two classes of modifications to gravity: those in which the graviton is given a small mass, and those in which Lorentz invariance is spontaneously broken. It elucidates the nature of cosmological perturbations in theories of massive bimetric gravity, including a potentially deadly instability. Theories of gravity beyond general relativity could explain why the expansion of the Universe is accelerating, obviating the need for a dark energy, and can also affect the evolution of the early Universe. Next, it investigates the nature of spacetime in massive gravity theories that contain two different spacetime metrics. Lastly, the strongest constraints to date are placed on the size of Lorentz-violating effects in the gravity sector during inflation.

Cosmology and Controversy: The Historical Development of Two Theories of the Universe

by Helge Kragh

For over three millennia, most people could understand the universe only in terms of myth, religion, and philosophy. Between 1920 and 1970, cosmology transformed into a branch of physics. With this remarkably rapid change came a theory that would finally lend empirical support to many long-held beliefs about the origins and development of the entire universe: the theory of the big bang. In this book, Helge Kragh presents the development of scientific cosmology for the first time as a historical event, one that embroiled many famous scientists in a controversy over the very notion of an evolving universe with a beginning in time. In rich detail he examines how the big-bang theory drew inspiration from and eventually triumphed over rival views, mainly the steady-state theory and its concept of a stationary universe of infinite age. In the 1920s, Alexander Friedmann and Georges Lemaître showed that Einstein's general relativity equations possessed solutions for a universe expanding in time. Kragh follows the story from here, showing how the big-bang theory evolved, from Edwin Hubble's observation that most galaxies are receding from us, to the discovery of the cosmic microwave background radiation. Sir Fred Hoyle proposed instead the steady-state theory, a model of dynamic equilibrium involving the continuous creation of matter throughout the universe. Although today it is generally accepted that the universe started some ten billion years ago in a big bang, many readers may not fully realize that this standard view owed much of its formation to the steady-state theory. By exploring the similarities and tensions between the theories, Kragh provides the reader with indispensable background for understanding much of today's commentary about our universe.

Cosmology and Politics in Plato’s Later Works

by O’meara Dominic J.

Knowledge of the structure of the cosmos, Plato suggests, is important in organizing a human community which aims at happiness. This book investigates this theme in Plato's later works, the Timaeus, Statesman, and Laws. Dominic J. O'Meara proposes fresh readings of these texts, starting from the religious festivals and technical and artistic skills in the context of which Plato elaborates his cosmological and political theories, for example the Greek architect's use of models as applied by Plato in describing the making of the world. O'Meara gives an account of the model of which Plato's world is an image; of the mathematics used in producing the world; and of the relation between the cosmic model and the political science and legislation involved in designing a model state in the Laws. Non-specialist scholars and students will be able to access and profit from the book.

Cosmology and String Theory (Fundamental Theories of Physics #197)

by Horaţiu Năstase

Cosmology describes the evolution of the Universe and is based on a description of its beginning from quantum fluctuations. String theory is the only known consistent theory of quantum gravity that can deal with the highest energy scales near the Planck energy, relevant for cosmology's beginning. As a result, only string theory can give a fully consistent picture of cosmological origins. This book describes the best current avenues for obtaining cosmology from string theory. It is aimed at graduate students, and also researchers, with some familiarity with cosmology and string theory, however no detailed knowledge is required.

Cosmology and the Scientific Self in the Nineteenth Century: Astronomic Emotions

by Howard Carlton

This book argues that while the historiography of the development of scientific ideas has for some time acknowledged the important influences of socio-cultural and material contexts, the significant impact of traumatic events, life threatening illnesses and other psychotropic stimuli on the development of scientific thought may not have been fully recognised. Howard Carlton examines the available primary sources which provide insight into the lives of a number of nineteenth-century astronomers, theologians and physicists to study the complex interactions within their ‘biocultural’ brain-body systems which drove parallel changes of perspective in theology, metaphysics, and cosmology. In doing so, he also explores three topics of great scientific interest during this period: the question of the possible existence of life on other planets; the deployment of the nebular hypothesis as a theory of cosmogony; and the religiously charged debates about the ages of the earth and sun. From this body of evidence we gain a greater understanding of the underlying phenomena which actuated intellectual developments in the past and which are still relevant to today’s knowledge-making processes.

Cosmology for the Curious

by Delia Perlov Alex Vilenkin

This book is a gentle introduction for all those wishing to learn about modern views of the cosmos. Our universe originated in a great explosion – the big bang. For nearly a century cosmologists have studied the aftermath of this explosion: how the universe expanded and cooled down, and how galaxies were gradually assembled by gravity. The nature of the bang itself has come into focus only relatively recently. It is the subject of the theory of cosmic inflation, which was developed in the last few decades and has led to a radically new global view of the universe. Students and other interested readers will find here a non-technical but conceptually rigorous account of modern cosmological ideas - describing what we know, and how we know it. One of the book's central themes is the scientific quest to find answers to the ultimate cosmic questions: Is the universe finite or infinite? Has it existed forever? If not, when and how did it come into being? Will it ever end? The book is based on the undergraduate course taught by Alex Vilenkin at Tufts University. It assumes no prior knowledge of physics or mathematics beyond elementary high school math. The necessary physics background is introduced as it is required. Each chapter includes a list of questions and exercises of varying degree of difficulty. This new edition includes hints for answering the questions and exercises, as well as extensions to the discussions on dark matter, quantum cosmology. A new chapter summarizing the standard cosmological model has also been added.

Cosmology in Gauge Field Theory and String Theory

by D. Bailin A. Love

Cosmology in Gauge Field Theory and String Theory focuses on the cosmological implications of the gauge theories of particle physics and of string theory. The book first examines the universe's series of phase transitions in which the successive gauge symmetries of the higher-temperature phase were spontaneously broken after the big bang, discussing relics of these phase transitions, more generic relics (baryons, neutrinos, axions), and supersymmetric particles (neutralinos and gravitinos). The author next studies supersymmetric theory, supergravity theory, and the constraints on the underlying field theory of the universe's inflationary era. The book concludes with a discussion of black hole solutions of the supergravity theory that approximates string theory at low energies and the insight that string theory affords into the microscopic origin of the Bekenstein-Hawking entropy.Cosmology in Gauge Field Theory and String Theory provides a modern introduction to these important problems from a particle physicist's perspective. It is intended as an introductory textbook for a first course on the subject at a graduate level.

Cosmology in Theological Perspective: Understanding Our Place in the Universe

by Olli-Pekka Vainio

Olli-Pekka Vainio, a leading expert in science and theology, explores questions concerning the place and significance of humans in the cosmos. Vainio introduces cosmology from a "state of the question" perspective, examining the history of the idea in dialogue with C. S. Lewis. This work, which is related to a NASA-funded project on astrobiology, ties into the ongoing debate on the relationship between Christian theism and scientific worldview and shows what the stakes are for religion and theology in the rise of modern science.

Cosmology in the Early Modern Age: A Web of Ideas (Logic, Epistemology, and the Unity of Science #56)

by Paolo Bussotti Brunello Lotti

This volume addresses the history and epistemology of early modern cosmology. The authors reconstruct the development of cosmological ideas in the age of ‘scientific revolution’ from Copernicus to Leibniz, taking into account the growth of a unified celestial-and-terrestrial mechanics. The volume investigates how, in the rise of the new science, cosmology displayed deep and multifaceted interrelations between scientific notions (stemming from mechanics, mathematics, geometry, astronomy) and philosophical concepts. These were employed to frame a general picture of the universe, as well as to criticize and interpret scientific notions and observational data.This interdisciplinary work reconstructs a conceptual web pervaded by various intellectual attitudes and drives. It presents an historical–epistemological unified itinerary which includes Copernicus, Kepler, Galileo, Descartes, Huygens, Newton and Leibniz. For each of the scientists and philosophers, a presentation and commentary is made of their cosmological views, and where relevant, outlines of their most relevant physical concepts are given. Furthermore, the authors highlight the philosophical and epistemological implications of their scientific works. This work is helpful both as a synthetic overview of early modern cosmology, and an analytical exposition of the elements that were intertwined in early-modern cosmology. This book addresses historians, philosophers, and scientists and can also be used as a research source book by post-graduate students in epistemology, history of science and history of philosophy.

Cosmos, Gods and Madmen: Frameworks in the Anthropologies of Medicine

by Lynch Littlewood

The social anthropology of sickness and health has always been concerned with religious cosmologies: how societies make sense of such issues as prediction and control of misfortune and fate; the malevolence of others; the benevolence (or otherwise) of the mystical world; local understanding and explanations of the natural and ultra-human worlds. This volume presents differing categorizations and conflicts that occur as people seek to make sense of suffering and their experiences. Cosmologies, whether incorporating the divine or as purely secular, lead us to interpret human action and the human constitution, its ills and its healing and, in particular, ways which determine and limit our very possibilities.

Cosmos: An Illustrated History of Astronomy and Cosmology

by John D. North

For millennia humans have studied the skies to help them grow crops, navigate the seas, and earn favor from their gods. We still look to the stars today for answers to fundamental questions: How did the universe begin? Will it end, and if so, how? What is our place within it? John North has been examining such questions for decades. In Cosmos, he offers a sweeping historical survey of the two sciences that help define our place in the universe: astronomy and cosmology. Organizing his history chronologically, North begins by examining Paleolithic cave drawings that clearly chart the phases of the moon. He then investigates scientific practices in the early civilizations of Egypt, Greece, China, and the Americas (among others), whose inhabitants developed sophisticated methods to record the movements of the planets and stars. Trade routes and religious movements, North notes, brought these ancient styles of scientific thinking to the attention of later astronomers, whose own theories-- such as Copernicus' planetary theory-- led to the Scientific Revolution. The work of master astronomers, including Ptolemy, Galileo, Kepler, and Newton, is described in detail, as are modern-day developments in astrophysics, such as the advent of radio astronomy, the brilliant innovations of Einstein, and the many recent discoveries brought about with the help of the Hubble telescope. This new edition brings North's seminal book right up to the present day, as North takes a closer look at last year's reclassification of Pluto as a "dwarf" planet and gives a thorough overview of current research. With more than two hundred illustrations and a comprehensive bibliography, Cosmos is the definitive history of astronomy and cosmology. It is sure to find an eager audience among historians of science and astronomers alike.
