This groundbreaking book presents a new perspective on three of cosmology's essential questions: What came before the Big Bang? What is the source of order in our universe? And what cosmic future awaits us?
Penrose shows how the expected fate of our ever-accelerating and expanding universe--heat death or ultimate entropy--can actually be reinterpreted as the conditions that will begin a new "Big Bang." He details the basic principles beneath our universe, explaining various standard and non-standard cosmological models, the fundamental role of the cosmic microwave background, the paramount significance of black holes, and other basic building blocks of contemporary physics. Intellectually thrilling and widely accessible, "Cycles of Time" is a welcome new contribution to our understanding of the universe from one of our greatest mathematicians and thinkers.

Introduction to General Relativity and Cosmology gives undergraduate students an overview of the fundamental ideas behind the geometric theory of gravitation and spacetime. Through pointers on how to modify and generalise Einstein's theory to enhance understanding, it provides a link between standard textbook content and current research in the field.Chapters present complicated material practically and concisely, initially dealing with the mathematical foundations of the theory of relativity, in particular differential geometry. This is followed by a discussion of the Einstein field equations and their various properties. Also given is analysis of the important Schwarzschild solutions, followed by application of general relativity to cosmology. Questions with fully worked answers are provided at the end of each chapter to aid comprehension and guide learning. This pared down textbook is specifically designed for new students looking for a workable, simple presentation of some of the key theories in modern physics and mathematics.

Contemporary science presents us with the remarkable theory that the universe began to exist about fifteen billion years ago with a cataclysmic explosion called `the Big Bang'. But was the Big Bang created (by God), or did it occur without cause? In this book two philosophers of the opposite viewpoints debate the question. Their arguments are based on Einstein's theory of relativity and include a discussion of the new quantum cosmology recently developed by Stephen Hawking in A Brief History of Time.

Black holes, once considered to be of purely theoretical interest, play an important role in observational astronomy and a range of astrophysical phenomena. This volume is based on a meeting held at the Space Telescope Science Institute, which explored the many aspects of black hole astrophysics. Written by world experts in areas of stellar-mass, intermediate-mass and supermassive black holes, these review papers provide an up-to-date overview of developments in this field. Topics discussed range from black hole entropy and the fate of information to supermassive black holes at the centers of galaxies, and from the possibility of producing black holes in collider experiments to the measurements of black hole spins. This is an invaluable resource for researchers currently working in the field, and for graduate students interested in this active and growing area of research.

This new graduate textbook adopts a pedagogical approach to contemporary cosmology that enables readers to build an intuitive understanding of theory and data, and of how they interact, which is where the greatest advances in the field are currently being made. Using analogies, intuitive explanations of complex topics, worked examples and computational problems, the book begins with the physics of the early universe, and goes on to cover key concepts such as inflation, dark matter and dark energy, large‑scale structure, and cosmic microwave background. Computational and data analysis techniques, and statistics, are integrated throughout the text, particularly in the chapters on late-universe cosmology, while another chapter is entirely devoted to the basics of statistical methods. A solutions manual for end-of-chapter problems is available to instructors, and suggested syllabi, based on different course lengths and emphasis, can be found in the Preface. Online computer code and datasets enhance the student learning experience.

From the days of antiquity to the time of the Middle Ages, intellectuals have widely assumed that stars were alive, a belief that gave the cosmos an important position not only in Greek religion, but also in discussions of human psychology and eschatology. In the third century AD, the Christian theologian Origen included such Hellenistic theories on the life and nature of the stars in his cosmology, a theory that would have important implications for early Christian theology. Moving through a wide range of Greek, Latin, and Oriental sources from antiquity to medieval times, this is the first thorough treatment of Origen's biblical theology. The second book in the new Oxford Early Christian Studies series, Origen and the Life of the Stars provides a new look at the roots of early Christian thought.

From the dawn of humankind, men and women have looked at change--as wrought by weather, the seasons, and, most strikingly, the inexorable advance of time--as something essentially to be feared. And partially from this fear the great religions and mythologies have arisen, systems which gave meaning to the ever-changing world, and, quite often, immortality to ourselves. By the late nineteenth century, the quest for ultimate meanings became largely the province of science, and today, change still figures (on the surface, at least) as a malevolent force: most of the cosmological theories formulated in recent years predict the ultimate extinction of the world by universal entropy.

Bringing together the evidence and insights of biology and physics, of astronomy and cosmology, Louise Young offers a profoundly original and stirring vision of order, form, change, and the creative forces in the universe. Opposing the long-held beliefs of many scientists that the universe is running down and will eventually collapse upon itself, Young eloquently argues that the tendency toward increasing entropy is merely one aspect of a single process that is creating more complex, highly organized, and more efficient forms of matter all the time, and at every level--from the microscopic to the stellar.

In vivid, compelling prose, Louise Young--an award-winning writer on science and a former physicist--takes us on an unforgettable tour of the world around us, showing how even the most ordinary aspects of life and the universe display a strangely beautiful symmetry. She clearly demonstrates that creation was not simply some big-bang eons ago, but rather is an ongoing process, one in which we are both witnesses and participants. Illustrating her findings with many remarkable photographs and fascinating examples ranging from geology to animal behavior, and from oceanography to genetics, Young gracefully canvasses the themes of growth, change creativity, and the mystery of the universe in a book that is as much poetry as it is science.

Based on solid scientific knowledge, yet informed by a refreshingly philosophical sensibility, The Unfinished Universe is a book that will inspire anyone who has ever questioned their place and purpose in a world filled with uncertainty and change.

"Evans and Berggren have produced a work that should be on the shelves of all students and scholars interested in the history of early astronomy. Because of the appeal of Geminos's text, this translation will provide a very valuable resource for teaching the history of astronomy and cosmology, as well as early science more generally. The translation is clear, the scholarly apparatus authoritative, and the commentary will serve the needs and interests of a wide range of readers."--Liba Taub, Director & Curator, Whipple Museum, and Reader, Department of History and Philosophy of Science, Cambridge University

"Evans and Berggren have provided both the specialist historian and the general scholar and reader with everything they might need to profit from the text. The introduction has a judicious discussion of the history of the book and its author, its place in the history of astronomy, its intended audience, and the general conceptual framework that it assumes. And the translators have done a splendid job of finding accurate English equivalents of the Greek terms and phrases."--Alexander Jones, University of Toronto

"Everything about this book is excellent. The translation is a model of clarity and the notes to each section explain the text in detail, both technically and historically. The extensive introduction is, by itself, the most detailed account to date of many, perhaps most, of the subjects treated by Geminos. The book will be of use and interest to everyone curious about ancient science, from the student to the specialist. Evans and Berggren have done such an excellent job in every way, their knowledge of the subject is so complete, that I can only admire their work andrecommend it as exemplary."--Noel M. Swerdlow, University of Chicago

This is a study of atomic nuclei, the properties of which find applications in diverse fields such as medicine and the generation of nuclear power. The explanations of nuclear structure and nuclear reactions in terms of constituent particles led to the discovery of new unstable particles culminating in the unified theory of electromagnetic and weak-nuclear interactions. In this new edition the author has updated the information and included a section on the relevance of recent discoveries to cosmology. Advances in accelerator and detector technology are noted and there is an account of nuclear reactions. Mathematical material is mostly to be found in the appendices. This book may be used as a first student text for courses in nuclear physics.

Is our universe dying?
Could there be other universes?
In "Parallel Worlds," world-renowned physicist and bestselling author Michio Kaku"--an" author who "has a knack for bringing the most ethereal ideas down to earth" "(Wall Street Journal)--takes readers on a fascinating tour of cosmology, M-theory, and its implications for the fate of the universe.
In his first book of physics since "Hyperspace, Michio Kaku begins by describing the extraordinary advances that have transformed cosmology over the last century, and particularly over the last decade, forcing scientists around the world to rethink our understanding of the birth of the universe, and its ultimate fate. In Dr. Kaku's eyes, we are living in a golden age of physics, as new discoveries from the WMAP and COBE satellites and the Hubble space telescope have given us unprecedented pictures of our universe in its infancy.
As astronomers wade through the avalanche of data from the WMAP satellite, a new cosmological picture is emerging. So far, the leading theory about the birth of the universe is the "inflationary universe theory," a major refinement on the big bang theory. In this theory, our universe may be but one in a multiverse, floating like a bubble in an infinite sea of bubble universes, with new universes being created all the time. A parallel universe may well hover a mere millimeter from our own.
The very idea of parallel universes and the string theory that can explain their existence was once viewed with suspicion by scientists, seen as the province of mystics, charlatans, and cranks. But today, physicists overwhelmingly support string-theory, and its latest iteration, M-theory, as it is this onetheory that, if proven correct, would reconcile the four forces of the universe simply and elegantly, and answer the question "What happened before the big bang?"
Already, Kaku explains, the world's foremost physicists and astronomers are searching for ways to test the theory of the multiverse using highly sophisticated wave detectors, gravity lenses, satellites, and telescopes. The implications of M-theory are fascinating and endless. If parallel worlds do exist, Kaku speculates, in time, perhaps a trillion years or more from now, as appears likely, when our universe grows cold and dark in what scientists describe as a big freeze, advanced civilizations may well find a way to escape our universe in a kind of "inter-dimensional lifeboat."
An unforgettable journey into black holes and time machines, alternate universes, and multidimensional space, "Parallel Worlds gives us a compelling portrait of the revolution sweeping the world of cosmology.

'An incredible tour of our universe's greatest mysteries' Professor Dan Hooper This cutting-edge book investigates the extraordinary potential of multimessenger astronomy to revolutionise our understanding of the universe The spectacular advances of modern astronomy have opened our horizon on an unexpected cosmos: a dark, mysterious universe, populated by enigmatic entities we know very little about, like black holes, or nothing at all, like dark matter and dark energy. This book discusses the extraordinary potential of a new discipline dubbed 'multimessenger astronomy', combining the traditional approach based on the observation of light from celestial objects, with a new method based on other 'messengers' - such as gravitational waves, neutrinos, and cosmic rays - that carry information from otherwise inaccessible corners of the universe. Interweaving the discussion of multimessenger astronomy with an exploration of the surprising connections between the study of the universe on the largest scales, and the physics of the infinitely small, this text provides an accessible and fascinating introduction to cutting-edge findings in recent cosmology which could soon revolutionize our understanding of the universe.

The world of science has been transformed. Where once astronomers sat at the controls of giant telescopes in remote locations, praying for clear skies, now they have no need to budge from their desks, as data arrives in their inbox. And what they receive is overwhelming; projects now being built provide more data in a few nights than in the whole of humanity's history of observing the Universe. It's not just astronomy either - dealing with this deluge of data is the major challenge for scientists at CERN, and for biologists who use automated cameras to spy on animals in their natural habitats. Artificial intelligence is one part of the solution - but will it spell the end of human involvement in scientific discovery? No, argues Chris Lintott. We humans still have unique capabilities to bring to bear - our curiosity, our capacity for wonder, and, most importantly, our capacity for surprise. It seems that humans and computers working together do better than computers can on their own. But with so much scientific data, you need a lot of scientists - a crowd, in fact. Lintott found such a crowd in the Zooniverse, the web-based project that allows hundreds of thousands of enthusiastic volunteers to contribute to science. In this book, Lintott describes the exciting discoveries that people all over the world have made, from galaxies to pulsars, exoplanets to moons, and from penguin behaviour to old ship's logs. This approach builds on a long history of so-called 'citizen science', given new power by fast internet and distributed data. Discovery is no longer the remit only of scientists in specialist labs or academics in ivory towers. It's something we can all take part in. As Lintott shows, it's a wonderful way to engage with science, yielding new insights daily. You, too, can help explore the Universe in your lunch hour.

Cosmology, the study of the universe, arouses a great deal of public interest, with serious articles both in the scientific press and in major newspapers, with many of the theories and concepts (e.g. the 'big bang' and 'black holes') discussed, often in great depth.Accordingly the book is divided into three parts:Part 1 is readable (and understandable) by anyone with a nodding acquaintance with the basic language of cosmology: events, lights paths, galaxies, black holes and so on. It covers the whole story of the book in a way as untechnical as possible given the scope of the topics covered.Part 2 covers the same ground again but with enough technical details to satisfy a reader with basic knowledge of mathematics and/or physics.Part 3 consists of appendices which are referred to in the other parts and which also contain the highly technical material omitted from Section 2.

Aliens. Ley lines. Water dowsing. Conspiracies and myths captivate imaginations and promise mystery and magic. Whether it's arguing about the moon landing hoax or a Frisbee-like Earth drifting through space, when held up to science and critical thinking, these ideas fall flat. In Weird Earth: Debunking Strange Ideas About Our Planet, Donald R. Prothero demystifies these conspiracies and offers answers to some of humanity's most outlandish questions. Applying his extensive scientific knowledge, Prothero corrects misinformation that con artists and quacks use to hoodwink others about geology-hollow earth, expanding earth, and bizarre earthquakes-and mystical and paranormal happenings-healing crystals, alien landings, and the gates of hell. By deconstructing wild claims such as prophesies of imminent natural disasters, Prothero provides a way for everyone to recognize dubious assertions. Prothero answers these claims with facts, offering historical and scientific context in a light-hearted manner that is accessible to everyone, no matter their background. With a careful layering of evidence in geology, archaeology, and biblical and historical records, Prothero's Weird Earth examines each conspiracy and myth and leaves no question unanswered.

In CONSTELLATIONS, award-winning astronomy writer Govert Schilling takes us on an unprecedented visual tour of all 88 constellations in our night sky. Much more than just a stargazer's guide, CONSTELLATIONS is complete history of astronomy as told by Schilling through the lens of each constellation. The book is organized alphabetically by constellation. Profiles of each constellation include basic information such as size, visibility, and number of stars, as well as information on the discovery and naming of the constellation and associated lore. Beyond details about the constellation itself is information about every astronomical event that took place or discovery made in the vicinity of the constellation. In the constellation of Cygnus (the Swan) we encounter the location of the first confirmed black hole. A stop at Gemini (the Twins) is a chance to say hello to the dwarf planet Pluto, and in Orion (the hunter) we find the location of the first identified gamma-ray burst. Stunning star maps throughout the book by acclaimed star mapmaker Wil Tirion show us the exact location of every constellation, the details of its structure, as well as its surrounding astronomical neighbors.

An award-winning science writer takes us into the lab to answer some of life's biggest questions: How was the universe created? And could we create our own? What if you could become God, with the ability to build a whole new universe? As startling as it sounds, modern physics suggests that within the next two decades, scientists may be able to perform this seemingly divine feat-to concoct an entirely new baby universe, complete with its own physical laws, star systems, galaxies, and even intelligent life. A Big Bang in a Little Room takes the reader on a journey through the history of cosmology and unravels-particle by particle, theory by theory, and experiment by experiment-the ideas behind this provocative claim made by some of the most respected physicists alive today. Beyond simply explaining the science, A Big Bang in a Little Room also tells the story of the people who have been laboring for more than thirty years to make this seemingly impossible dream a reality. What has driven them to continue on what would seem, at first glance, to be a quixotic quest? This mind-boggling book reveals that we can nurse other worlds in the tiny confines of a lab, raising a daunting prospect: Was our universe, too, brought into existence by a daring creator?

Demonstrating the unity of Tolkien's created world across Middle-earth's Ages. An in-depth examination of the role of divine beings in Tolkien's work, Tolkien's Cosmology: Divine Beings and Middle-earth brings together Tolkien's many references to such beings and analyzes their involvement within his created world. Unlike many other commentators, Sam McBride asserts that a careful reading of the whole of the author's corpus shows a coherent, if sometimes contradictory, divine presence in the world.In The Silmarillion, an epic history of the First Age of Middle-earth, Tolkien describes the Ainur, angelic beings under the direction of Eru Iluvatar, the legendarium's god, as creators of physical reality. Some of these divine beings, the Valar and the Maiar, enter physical reality to oversee its development and prepare for the appearance of sentient life forms in Middle-earth: Elves and Humans, Dwarves, and eventually Hobbits. In the early stages of this history, the Valar and Maiar interact directly with Elves and Humans, opposing the work of evil beings led by Melkor. Yet Tolkien appears, at first glance, to have ignored this pantheon in The Hobbit and The Lord of the Rings, set in the Third Age of Middle-earth. Tolkien's letters, however, suggest the cosmological structure continues. And representatives of the Valar and Maiar can be seen at work, such as Gandalf and Saruman. Tolkien also introduces hints that his divine beings continue to influence events invisibly, as with the prominence of luck in The Hobbit and fortuitous weather conditions in The Lord of the Rings. In the end, McBride argues, Tolkien's cosmology allows room for everything from poor decision-making to evil, suffering, and death, all part of a belief system that will make the final victory of Good much more powerful.

The subject matter of this work is an area of Lorentzian geometry which has not been heretofore much investigated: Do there exist Lorentzian manifolds all of whose light-like geodesics are periodic? A surprising fact is that such manifolds exist in abundance in (2 + 1)-dimensions (though in higher dimensions they are quite rare). This book is concerned with the deformation theory of M2,1 (which furnishes almost all the known examples of these objects). It also has a section describing conformal invariants of these objects, the most interesting being the determinant of a two dimensional "Floquet operator," invented by Paneitz and Segal.

The Physics of the Early Universe is an edited and expanded version of the lectures given at a recent summer school of the same name. Its aim is to present an advanced multi-authored textbook that meets the needs of both postgraduate students and young researchers interested in, or already working on, problems in cosmology and general relativity, with emphasis on the early universe. A particularly strong feature of the present work is the constructive-critical approach to the present mainstream theories, the careful assessment of some alternative approaches, and the overall balance between theoretical and observational considerations. As such, this book will also benefit experienced scientists and nonspecialists from related areas of research.

Astronomer Joseph Silk explores the Universe from its beginnings to its ultimate fate. He demonstrates how cosmologists study cosmic fossils and relics from the distant past to construct theories of the birth, evolution and future of the Universe. Stars, galaxies, dark matter and dark energy are described, as successive chapters detail the evolution of the Universe from a fraction of a microsecond after the Big Bang. Silk describes how physicists apply theories of subatomic particles to recreate the first moments of the Big Bang, and how astronomers chart the vast depths of space to glimpse how the most distant galaxies formed. He gives an account of the search for dark matter and the dark energy that will determine the ultimate fate of the Universe. Joseph Silk is the Savilian Professor of Astronomy and Head of the Astrophysics Department at the University of Oxford. He was previously Professor of Astronomy at the University of California, Berkeley. He holds a BA in Mathematics from Clare College, Cambridge, and a PhD in Astronomy from Harvard University. Silk is the author, or co-author, of many books, including The Left Hand of Creation (Basic Books, 1994) and A Short History of the Universe (WH Freeman, 1997). He is a Fellow of the Royal Society, the American Physical Society, and the American Association for the Advancement of Science.

In the early 1990s, a NASA-led team of scientists changed the way we view the universe. With the COBE (Cosmic Background Explorer) project, they showed that the microwave radiation that fills the universe must have come from the Big Bang--effectively proving the Big Bang theory beyond any doubt. It was one of the greatest scientific findings of our generation, perhaps of all time. In "The Very First Light," John Mather, one of COBE's leaders, and science writer John Boslough tell the story of how it was achieved. A gripping tale of big money, bigger egos, tense politics, and cutting-edge engineering, "The Very First Light" offers a rare insider's account of the world of big science.

Delineating the huge strides taken in cosmology in the past ten years, this much-anticipated second edition of Malcolm Longair's highly appreciated textbook has been extensively and thoroughly updated. It tells the story of modern astrophysical cosmology from the perspective of one of its most important and fundamental problems – how did the galaxies come about? Longair uses this approach to introduce the whole of what may be called "classical cosmology". What’s more, he describes how the study of the origin of galaxies and larger-scale structures in the Universe has provided us with direct information about the physics of the very early Universe.
