| modern cosmology: Modern Cosmology Scott Dodelson, 2003-03-30 Modern Cosmology begins with an introduction to the smooth, homogeneous universe described by a Friedman-Robertson-Walker metric, including careful treatments of dark energy, big bang nucleosynthesis, recombination, and dark matter. From this starting point, the reader is introduced to perturbations about an FRW universe: their evolution with the Einstein-Boltzmann equations, their generation by primordial inflation, and their observational consequences. These consequences include the anisotropy spectrum of the cosmic microwave background (CMB) featuring acoustic peaks and polarization, the matter power spectrum with baryonic wiggles, and their detection via photometric galaxy surveys, redshift distortions, cluster abundances, and weak lensing. The book concludes with a long chapter on data analysis. Modern Cosmology is the first book to explain in detail the structure of the acoustic peaks in the CMB, the E/B decomposition in polarization which may allow for detection of primordial gravity waves, and the modern analysis techniques used on increasingly large cosmological data sets. Readers will gain the tools needed to work in cosmology and learn how modern observations are rapidly revolutionizing our picture of the universe. - Provides foundations, calculations, and interpretations which illuminate current thinking in cosmology - Covers the major advances in cosmology over the past decade - Includes over 100 unique, pedagogical figures |

| modern cosmology: The True Story of Modern Cosmology Emilio Elizalde, 2021-08-19 This book tells the story of how, over the past century, dedicated observers and pioneering scientists achieved our current understanding of the universe. It was in antiquity that humankind first attempted to explain the universe often with the help of myths and legends. This book, however, focuses on the time when cosmology finally became a true science. As the reader will learn, this was a slow process, extending over a large part of the 20th century and involving many astronomers, cosmologists and theoretical physicists. The book explains how empirical astronomical data (e.g., Leavitt, Slipher and Hubble) were reconciled with Einstein's general relativity; a challenge which finally led Friedmann, De Sitter and Lemaître, and eventually Einstein himself, to a consistent understanding of the observational results. The reader will realize the extraordinary implications of these achievements and how deeply they changed our vision of the cosmos: From being small, static, immutable and eternal, it became vast and dynamical - originating from (almost) nothing, and yet now, nearly 14 billion years later, undergoing accelerated expansion. But, as always happens, as well as precious knowledge, new mysteries have also been created where previously absolute certainty had reigned. |
| modern cosmology: Modern Cosmology D. W. Sciama, 1971-08-31 The exploration of the Universe, as conducted by physicists, astronomers, and cosmologists was one of the greatest intellectual adventures of the mid-twentieth century. This book, first published in 1971, tells the story of their achievements and the insight gained into the structure, history, working and scale of our Universe. Dr Sciama describes the major components of the Universe as understood at the beginning of the 1970s: the stars, galaxies, radio-galaxies and quasi-stellar objects. He discusses in detail the red shift of the lines in their optical spectra, which leads to the idea that the Universe is expanding. Theoretical discussion of the expanding Universe suggests the possibility that intergalactic space may contain a significant quantity of matter and be the seat of important physical activity. The issues involved are thoroughly debated. Also discussed is the discover and significance of the 3'K' cosmic microwave radiation, its relation to the hot big bang and the helium problem, to cosmic high energy processes and to questions of isotropy. |

| modern cosmology: Modern Cosmology in Retrospect B. Bertotti, 1990-10-25 Modern cosmology aims to determine the origin, evolution, and ultimate fate of the Universe. This is an area of modern science that has engendered fierce debates which have captured public interest. This book recounts the development of modern cosmology, in chapters contributed by many of the leading protagonists. It is a fascinating account of physical and observational cosmology, the great cosmological debates, important observations and the riddle of dark matter. The enormous controversy surrounding the Big Bang theory is retold in personal recollections from H. Bondi, W. McCrea, and Fred Hoyle. This is followed by chapters on the discovery of cosmic radio waves and the contributions made by radio astronomers to current cosmology. The book concludes with a tribute to some of the pioneers of cosmology. |
| modern cosmology: Modern Cosmology & Philosophy John Leslie, 1998 Did the universe originate from a big bang as argued by leading astrophysicists and others? Or does some other theory more accurately describe its beginnings? Are there other forms of life in the universe? What about other universes?

| modern cosmology: Cosmology Steven Weinberg, 2008-02-21 This book is unique in the detailed, self-contained, and comprehensive treatment that it gives to the ideas and formulas that are used and tested in modern cosmological research. It divides into two parts, each of which provides enough material for a one-semester graduate course. The first part deals chiefly with the isotropic and homogeneous average universe; the second part concentrates on the departures from the average universe. Throughout the book the author presents detailed analytic calculations of cosmological phenomena, rather than just report results obtained elsewhere by numerical computation. The book is up to date, and gives detailed accounts of topics such as recombination, microwave background polarization, leptogenesis, gravitational lensing, structure formation, and multifield inflation, that are usually treated superficially if at all in treatises on cosmology. Copious references to current research literature are supplied. Appendices include a brief introduction to general relativity, and a detailed derivation of the Boltzmann equation for photons and neutrinos used in calculations of cosmological evolution. Also provided is an assortment of problems. |

| modern cosmology: Physical Foundations of Cosmology Viatcheslav Mukhanov, 2005-11-10 Inflationary cosmology has been developed over the last twenty years to remedy serious shortcomings in the standard hot big bang model of the universe. This textbook, first published in 2005, explains the basis of modern cosmology and shows where the theoretical results come from. The book is divided into two parts; the first deals with the homogeneous and isotropic model of the Universe, the second part discusses how inhomogeneities can explain its structure. Established material such as the inflation and quantum cosmological perturbation are presented in great detail, however the reader is brought to the frontiers of current cosmological research by the discussion of more speculative ideas. An ideal textbook for both advanced students of physics and astrophysics, all of the necessary background material is included in every chapter and no prior knowledge of general relativity and quantum field theory is assumed. |
| modern cosmology: Trends in Modern Cosmology Abraao Jesse Capistrano, 2017-06-07 The modern cosmology has been turned into an outstanding field of active research through the years. Today, we have more scientific data in modern cosmology than we could get rid of it, which makes the present days an exciting era for scientific knowledge. Trends in Modern Cosmology invites the reader to tackle the big questions of the universe from cultural aspects of cosmology and its influence on arts, philosophy, and politics to more specialized technical advances in the field as the physics of dark sector, black holes, galaxies, large structure formation, and particles. In fact, it reveals our endless searching for the better understanding of the universe as a legacy of knowledge for next generations. |
| modern cosmology: Encyclopedia of Cosmology (Routledge Revivals) Norriss S. Hetherington, 2014-04-08 The Encyclopedia of Cosmology, first published in 1993, recounts the history, philosophical assumptions, methodological ambiguities, and human struggles that have influenced the various responses to the basic questions of cosmology through the ages, as well as referencing important scientific theories. Just as the recognition of social conventions in other cultures can lead to a more productive perspective on our own behaviour, so too a study of the cosmologies of other times and places can enable us recognise elements of our own cosmology that might otherwise pass as inevitable developments. Apart from modern natural science, therefore, this volume incorporates brief treatments of Native American, Cave-Dweller, Chinese, Egyptian, Islamic, Megalithic, Mesopotamian, Greek, Medieval and Copernican cosmology, leading to an appreciation of cosmology as an intellectual creation, not merely a collection of facts. It is a valuable reference tool for any student or academic with an interest in the history of science and cosmology specifically. |

| modern cosmology: Cosmology for the Curious Delia Perlov, Alex Vilenkin, 2024-10-03 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. |
| modern cosmology: The Zen in Modern Cosmology Harry C. S. Lam, 2008 According to Modern Cosmology, our Universe came from a primordial state 13.7 billion years ago, with no matter and very little energy. In other words, it was almost empty. Where do the stars and galaxies, and everything else in the present universe come from then?This captivating book provides an answer to this question, and explains the observations and evidence behind the assertion of an almost empty primordial universe. Aimed at a general audience, it assumes no prior knowledge of astronomy or physics.The emptiness of the primordial universe is reminiscent of the emptiness in Zen Buddhism. The similarities and differences of these two forms of emptiness are explored. |

| modern cosmology: God, the Multiverse, and Everything Rodney D. Holder, 2017-03-02 Modern cosmology tells us that the universe is remarkably 'fine-tuned' for life. If the constants of physics or the initial conditions at the Big Bang were different by the smallest of margins then the universe would have been dull and lifeless. Why should the universe be so accommodating to life? Many cosmologists believe that the existence of many universes can explain why ours is so special. In this book Rodney Holder subjects this 'multiverse' hypothesis to rigorous philosophical critique. A multitude of problems is exposed. Going substantially further than existing treatments, Holder argues that divine design is the best explanation for cosmic fine-tuning, specifically that design by God is a superior explanation in terms of both initial plausibility and explanatory power, and is therefore the most rational position to take on the basis of the cosmological data. |
| modern cosmology: The Little Book of Cosmology Lyman Page, 2020-04-07 The cutting-edge science that is taking the measure of the universe The Little Book of Cosmology provides a breathtaking look at our universe on the grandest scales imaginable. Written by one of the world's leading experimental cosmologists, this short but deeply insightful book describes what scientists are revealing through precise measurements of the faint thermal afterglow of the Big Bang—known as the cosmic microwave background, or CMB—and how their findings are transforming our view of the cosmos. Blending the latest findings in cosmology with essential concepts from physics, Lyman Page first helps readers to grasp the sheer enormity of the universe, explaining how to understand the history of its formation and evolution in space and time. Then he sheds light on how spatial variations in the CMB formed, how they reveal the age, size, and geometry of the universe, and how they offer a blueprint for the formation of cosmic structure. Not only does Page explain current observations and measurements, he describes how they can be woven together into a unified picture to form the Standard Model of Cosmology. Yet much remains unknown, and this incisive book also describes the search for ever deeper knowledge at the field's frontiers—from quests to understand the nature of neutrinos and dark energy to investigations into the physics of the very early universe. |

| modern cosmology: Let There Be Light Howard Smith, Ph.D., 2010-10-04 In Let There Be Light, Howard Smith, a research astrophysicist and traditionally observant Jew, explores how modern scientific understandings of the cosmos complement Judaism's ancient mystical theology, the Kabbalah. He argues that science and religion are not only compatible, but that a healthy, productive dialogue between the two sheds light on ethics, free will, and the nature of life, while at the same time rejecting fundamentalist misinterpretation and the pseudoscience of creationism. Written for a general audience, yet supported by the most current and accurate scientific research, the book discusses topics such as modern quantum mechanics and mystical notions of awareness; how Kabbalah's ten sefirot mirror the developing phases of an inflationary universe; and the surprising parallels that exist between the Big Bang theory and Kabbalah's origin theory. Smith delves into complex ideas without resorting to jargon or mathematical equations, creating an intelligent, authoritative work accessible to all readers. |
| modern cosmology: Introduction to Cosmology Matts Roos, 2015-03-09 The Fourth Edition of Introduction to Cosmology provides a concise, authoritative study of cosmology at an introductory level. Starting from elementary principles and the early history of cosmology, the text carefully guides the student on to curved spacetimes, special and general relativity, gravitational lensing, the thermal history of the Universe, and cosmological models, including extended gravity models, black holes and Hawking's recent conjectures on the not-so-black holes. Introduction to Cosmology, Fourth Edition includes: New theoretical approaches and in-depth material on observational astrophysics and expanded sections on astrophysical phenomena Illustrations throughout and comprehensive references with problems at the end of each chapter and a rich index at the end of the book Latest observational results from WMAP9, ACT, and Planck, and all cosmological parameters have been brought up to date. This text is invaluable for undergraduate students in physics and astrophysics taking a first course in cosmology. Extensively revised, this latest edition extends the chapter on cosmic inflation to the recent schism on eternal inflation and multiverses. Dark matter is discussed on galaxy and cluster scales, and dark matter candidates are presented, some requiring a five-dimensional universe and several representing various types of exotica. In the context of cosmic structures the cold dark matter paradigm is described. Dark energy models include the cosmological constant, quintessence and other single field models, f(R) models and models requiring extra dimensions. |
| modern cosmology: God's Two Books Kenneth James Howell, 2002 This is an analysis of how 16th- and 17th-century astronomers and theologians in Northern Protestant Europe used science and religion to challenge and support one another.

| modern cosmology: The State of the Universe Pedro Ferreira, 2012-10-18 A masterly overview of the development of cosmological thinking from the Greeks, via Newton and Einstein, to the present day. It is science's last and greatest challenge: fathoming the depths of the night sky. The objective: to crack the cosmic code, to unravel the blueprint for nature's grandest conception, a machine constructed on an unimaginably vast scale - the Universe itself. Today's model of an expanding Universe - the big bang cosmology - is actually built on principles derived from a few simple mathematical equations. Gravity-warped space time, quantum mechanics, the physics of the subatomic, these crucial insights, stemming from Einstein's revolutionary theories of relativity, have led to a simple and elegant framework within which the whole of the Universe, over billions of years, has been described. But recent evidence has begun to make wrinkles in the neat fabric of the big bang cosmology. There is now overwhelming evidence that there is far more stuff in the Universe than we can see. What, and where, is this 'dark matter'? And it now appears that the expansion of the Universe is accelerating: something out there - some exotic 'dark energy' - is acting against gravity to push space and time apart. While offering a critical view of how all the pieces in our current model fit together, Pedro Ferreira argues that Einstein's Universe may be just another stepping stone towards a new, more profound and effective cosmology in the future. |
| modern cosmology: Cosmology Norriss S. Hetherington, 2023-05-31 This book is a collection of contributions examining cosmology from multiple perspectives.

| modern cosmology: Matter and Spirit in the Universe Helge Kragh, 2004 Cosmology is an unusual science with an unusual history. This book examines the formative years of modern cosmology from the perspective of its interaction with religious thought. As the first study of its kind, it reveals how closely associated the development of cosmology has been with considerations of a philosophical and religious nature. From nineteenth-century thermodynamics to the pioneering cosmological works of Georges Lematre and Arthur E Milne, religion has shaped parts of modern cosmological theory. By taking the religious component seriously, a new and richer history of cosmology emerges. |
| modern cosmology: The End of Everything Katie Mack, 2020-08-04 A NEW YORK TIMES NOTABLE BOOK * AN NPR SCIENCE FRIDAY BOOK CLUB SELECTION* NAMED A BEST BOOK OF THE YEAR BY THE WASHINGTON POST, THE ECONOMIST, NEW SCIENTIST, PUBLISHERS WEEKLY, and THE GUARDIAN From the cohost of the podcast The Universe with John Green and one of the most dynamic stars in astrophysics, an “engrossing, elegant” (The New York Times) look at five ways the universe could end, and the mind-blowing lessons each scenario reveals about the most important concepts in cosmology. We know the universe had a beginning. With the Big Bang, it expanded from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life as we know it. But what happens to the universe at the end of the story? And what does it mean for us now? Dr. Katie Mack has been contemplating these questions since she was a young student, when her astronomy professor informed her the universe could end at any moment, in an instant. This revelation set her on the path toward theoretical astrophysics. Now, with lively wit and humor, she takes us on a mind-bending tour through five of the cosmos’s possible finales: the Big Crunch, Heat Death, the Big Rip, Vacuum Decay (the one that could happen at any moment!), and the Bounce. Guiding us through cutting-edge science and major concepts in quantum mechanics, cosmology, string theory, and much more, The End of Everything is a wildly fun, surprisingly upbeat ride to the farthest reaches of all that we know. |
| modern cosmology: Fundamentals of Cosmology James Rich, 2013-04-17 This is a textbook intended for students and researchers who wish to under stand the physics of standard big bang cosmology and how it is used to interpret the most recent observations. It is based on courses given over the last seven years to beginning graduate students at the University of Paris and to advanced undergraduates at l'Ecole Poly technique. Since the great major ity of these students did not intend to become professional cosmologists, I have emphasized subjects that should be of general interest. Progress in observations over the last ten years has been truly astounding and a new textbook might be justified simply to report on recent break throughs. The traditional successes of modern cosmology are well-known. Among these are the dynamical understanding of the universal expansion, the prediction of the cosmic microwave background radiation, and the calculation of the abundances of the light elements. To these we can add new observa tions that suggest that we are beginning the era of precision cosmology. Perhaps most spectacular was the observation this year of the first acoustic peak in the anisotropy spectrum of the cosmic background radiation by the Boomerang and Maxima collaborations. These beautiful measurements have convinced many people that the universe has a nearly critical energy density and that a complete understanding of structure formation may be at hand. |
