This book provides a concise introduction to the mathematical aspects of the origin, structure and evolution of the universe. The book begins with a brief overview of observational and theoretical cosmology, along with a short introduction of general relativity. It then goes on to discuss Friedmann models, the Hubble constant and deceleration parameter, singularities, the early universe, inflation, quantum cosmology and the distant future of the universe. This new edition contains a rigorous derivation of the Robertson-Walker metric. It also discusses the limits to the parameter space through various theoretical and observational constraints, and presents a new inflationary solution for a sixth degree potential. This book is suitable as a textbook for advanced undergraduates and beginning graduate students. It will also be of interest to cosmologists, astrophysicists, applied mathematicians and mathematical physicists.

Here is a self-contained exposition of the theory of gravitational solitons and provides a comprehensive review of exact soliton solutions to Einstein's equations. The text begins with a detailed discussion of the extension of the Inverse Scattering Method to the theory of gravitation, starting with pure gravity and then extending it to the coupling of gravity with the electromagnetic field. There follows a systematic review of the gravitational soliton solutions based on their symmetries. These solutions include some of the most interesting in gravitational physics such as those describing inhomogeneous cosmological models, cylindrical waves, the collision of exact gravity waves, and the Schwarzschild and Kerr black holes.

The Great Silence explores the multifaceted problem named after the great Italian physicist Enrico Fermi and his legendary 1950 lunchtime question "Where is everybody?" In many respects, Fermi's paradox is the richest and the most challenging problem for the entire field of astrobiology and the Search for ExtraTerrestrial Intelligence (SETI) studies. This book shows how Fermi's paradox is intricately connected with many fields of learning, technology, arts, and even everyday life. It aims to establish the strongest possible version of the problem, to dispel many related confusions, obfuscations, and prejudices, as well as to offer a novel point of entry to the many solutions proposed in existing literature. Cirkovic argues that any evolutionary worldview cannot avoid resolving the Great Silence problem in one guise or another.

People worldwide are questioning the materialistic, mechanistic scientific pradigm that has been the dominant cosmology for the past one hundred years or so. The purpose of The New Paradigm is to provide a philosophical foundation for a spiritual cosmology that can incorporate both modern science and ancient wisdom. This is a paradigm that many have hoped would arise to usher in the predicted New Age of elevated spiritual awareness and understanding. The New Paradigm offers insights into the nature of people and their relationship to the one universal Spirit they have called God. This philosophical treatise makes a strong case to the effect that people are created from the substance of Spirit and hence are powerful spiritual beings who have forgotten their true nature and origin.

This book is a comprehensive and coherent introduction to the role of cosmic strings and other topological defects in the universe. After an introduction to standard cosmological theory and the theory of phase transitions in the early universe, the book then describes, in turn, the properties, formation, and cosmological implications of cosmic strings, monopoles, domain walls and textures. It concludes with a chapter considering the role of topological defects in inflationary universe models. Ample introductory material is included to make the book readily accessible. It will be of interest to graduate students and researchers in particle physics, astrophysics and cosmology.

The discovery of life on other planets would be perhaps the most momentous revelation in human history, more disorienting and more profound than either the Copernican or Darwinian revolutions, which knocked the earth from the center of the universe and humankind from its position of lofty self-regard. In Here Be Dragons, astronomer David Koerner and neurobiologist Simon LeVay offer a scientifically compelling and colorful account of the search for life beyond Earth.
The authors survey the work of biologists, cosmologists, computer theorists, NASA engineers, SETI researchers, roboticists, and UFO enthusiasts and debunkers as they attempt to answer the greatest remaining question facing humankind: Are we alone? From their "safe haven of skepticism" the authors venture into the "rough seas of speculation," where theory and evidence run the gamut from hard science to hocus pocus. Arguing that the universe is spectacularly suited for the evolution of living creatures, Koerner and LeVay give us ringside seats at the great debates of Big Science. The contenitous arguments about what really happens in evolution, the acrimonious UFO controversy, and the debate over intelligence versus artificial intelligence shed new light on the wildly divergent claims about the universe and life's place in it. The authors argue that while no direct evidence of extraterrestrial life yet exists, habitats and chemical building blocks for life abound in the universe. A wealth of new astronomical techniques and space missions may provide this evidence early in the next century.
Lucidly written and scientifically rigorous, Here Be Dragons presents everything we know thus far about the emergence of intelligent life here on earth and, perhaps, beyond.

In this book, the authors present current research in the study of the evolution, theory and thermodynamics of black holes. Topics discussed include the effective theory of a matter field near the event horizon of a black hole; dilatonic black holes in 4D Gauss-Bonnet gravity; the relationship between the tunnelling rate of a rotating black hole and the first law of black hole thermodynamics; alternative theories of gravity without black holes; exotic smoothness structures for the application of standard Einstein equations to black hole structures; and lower dimensional quantum black holes.

This book is a historical account of how natural philosophers and scientists have endeavoured to understand the universe at large, first in a mythical and later in a scientific context. Starting with the creation stories of ancient Egypt and Mesopotamia, the book covers all the major events in theoretical and observational cosmology, from Aristotle's cosmos over the Copernican revolution to the discovery of the accelerating universe in the late 1990s. It presents cosmology as a subject including scientific as well as non-scientific dimensions, and tells the story of how it developed into a true science of the heavens. Contrary to most other books in the history of cosmology, it offers an integrated account of the development with emphasis on the modern Einsteinian and post-Einsteinian period. Starting in the pre-literary era, it carries the story onwards to the early years of the 21st century.

The authors are all world-renowned experts both for their research and teaching skills. In the fast-moving field of structure formation, this book provides advanced undergraduate and graduate students with a welcome textbook which unites the latest theory and observations.

Many people have observed that the "new cosmology" seems to have an affinity to, or at least room for, a religious understanding of the nature of reality. Why is this so, and what does it mean for contemporary spirituality? In this book Paul Brockelman argues that the new scientific cosmology also functions as a religious creation story, or "cosmogony," with the power to provide our culture with a new vision of an ultimately meaningful sacred reality, and a corresponding basis for a comprehensive guide to living.

The Planetary Scientist's Companion is a comprehensive and practical book of facts and data about the Sun, planets, asteroids, comets, meteorites, and Kuiper belt and Centaur objects in our solar system. Also covered are properties of nearby stars, the interstellar medium, and extra-solar planetary systems.

Illustrated throughout with photographs, sky charts, and diagrams.

Our Cosmic Origins tells the story of our remarkable adventure on this planet, beginning with a single event in the depths of space. It traces the rich and wonderful history of the Universe, from the Big Bang to the creation of atoms and molecules, from the formation of stars and planets to the emergence of life on Earth. Delsemme brings together cosmology, astronomy, geology, biochemistry, and biology to create a unique look at the complex story of the Universe. He chronicles how the first light atoms were made and formed stars and how heavier atoms were cooked in stars and scattered in space, creating dust mrains and organic molecules. He examines the growing eomplexity of plant and animal life, including the emergence and extinction of dinosaurs. Our Cosmic Origins shows how the coupling of eye and brain led to self-awareness and intelligence. It explores the cosmic coincidences that might explain our existence and concludes with the tantalizing suggestion that intelligent alien life is likely. This provocative book will appeal to anyone who has ever looked at the sky and wondered how we got here. Originally published in French, this edition has been revised to include the most recent research in astronomy and cosmology. Armand Delsemme has published four books and over 230 scientific papers. He received a Sigma Xi award for outstanding research and has had, by order of the International Astronomical Union, an asteroid named after him.

That is merely surface reality. Beneath it lies the deeper reality which reveals itself when the mind is without any armour, when the heart opens up, and when reason becomes free from all sorts of cunningness and instrumentality. Only then does music touch us, and take us to the depths of our existence." The book is full of revelationsAZan intimate engagement with the freshness of the morning and the depth of the dark silent night.

Carl Sagan's many contributions to science and society have been profound and far-reaching, influencing millions of people around the world. He carried out significant research in planetary science, was closely associated with the US space program, created the highly acclaimed television series Cosmos, and was the Pulitzer Prize-winning author of many best-selling popular science books. Carl Sagan's Universe is a fascinating and beautifully illustrated collection of articles by a distinguished team of authors, and covers the many fields of science, education, policy making, and related areas in which Sagan worked. The book is divided into four sections, the first two of which provide an absorbing overview of the US space program (as well as a complementary account of the Russian program), and of the history and current status of the search for extraterrestrial life. The final two sections deal with the importance of science education in the successful development of a technological society, and of the shaping of science policy in tackling the problems facing us today. Also included is a separate chapter by Sagan himself, discussing the place and role of our planet and mankind in the universe. Written in honour of Carl Sagan's many achievements, this book will fascinate and reward anyone interested in planetary science and exploration, the search for extraterrestrial life, or the role of science in the modern world.

This controversial book examines one of the most fundamental questions of modern cosmology: how much matter is there in the Universe? This issue affects theories of the origin and evolution of the Universe as well as its geometrical structure and ultimate fate. The authors address this debate and point out the most likely avenues for determining the actual density of Universe matter in both visible and invisible forms by pulling together evidence from all available sources. They conclude that the balance of arguments presently lies with a density of around twenty percent of the critical density required for the Universe to ultimately recollapse. Written by two eminent cosmologists, this topical and provocative book will be essential reading for all cosmologists and astrophysicists.

Working physicists, and especially astrophysicists, value a good `back-of-the-envelope' calculation, meaning a short, elegant computation or argument that starts from general principles and leads to an interesting result. This book guides students on how to understand astrophysics using general principles and concise calculations - endeavouring to be elegant where possible and using short computer programs where necessary. The material proceeds in approximate historical order. The book begins with the Enlightenment-era insight that the orbits of the planets is easy, but the orbit of the Moon is a real headache, and continues to deterministic chaos. This is followed by a chapter on spacetime and black holes. Four chapters reveal how microphysics, especially quantum mechanics, allow us to understand how stars work. The last two chapters are about cosmology, bringing us to 21st-century developments on the microwave background and gravitational waves.

This upper-division textbook describes the composition and evolution of material objects in the universe. The survey begins with a discussion of terrestrial materials and ends with the composition of quasars and distant galaxies. There are two main themes: chemical processes responsible for the abundances we observe, and nuclear processes in which the chemical elements originate. The author presents a total pedagogic synthesis of the subject, building on the basic information in the first chapters to lead into a fuller explanation of the composition of the planets and stellar and primordial nucleosynthesis. The later chapters treat the analytical methods of stellar and nebular spectra, and move on to the composition of stars and galaxies. The book is fully referenced and includes problem sets for the student.

The quest for the farthest objects in the Universe remains one of the most challenging areas of modern astronomical research. Peering deeper and deeper into space reveals the most distant and powerful objects known and so unveils the embryonic epochs of the Universe not long after its birth in the Big Bang. Four world experts--chosen for their ability to communicate research astronomy at a popular level--each contributes a chapter to this lucid survey. They address the fundamental issues of scale in the Universe; the ghostly etchings seen on the cosmic background radiation; quasars and their evolution; and galaxy birth. This fascinating and accessible account offers an exceptional chance for the general audience to share in the excitement of today's forefront research of the early Universe.

This timely collection of articles celebrates the work of Maurice Shapiro, who is internationally distinguished for his contributions to the development of cosmic-ray physics. The papers focus primarily on cosmic-ray physics, X-ray, gamma-ray and neutrino astronomy and cosmology. The scope extends from the inner solar system to distant radio galaxies. Each chapter is written by a leading scientist in the field, including James Van Allen, discoverer of the Van Allen radiation belt and Fred Reines, discoverer of the neutrino.

This book is a quantitative introduction to what is known or theorized about the structure and evolution of galactic systems. It begins with a general introduction to galaxies and a summary of our empirical observations of galaxies in the universe, including our own. There are then three chapters on galactic structure: the manner in which motions of stars determine galactic shape, the determination of galactic masses, and the structure of discs in spirals. Galactic evolution, especially changes in chemical composition over time, is then covered. The book concludes with a discussion of the origin of galaxies and their relation to more general questions in cosmology. The presentation is sufficiently mathematical so that quantitative results can be discussed in detail. Throughout, the author stresses what are currently accepted results and what theories may need revision in what continues to be a rapidly developing subject.

In this volume, six leading cosmologists provide a current "state of the universe" report: what we have learned about its nature, but also what pieces are still missing from the cosmic puzzle. The roster of contributors reads like a Who's Who of modern cosmology: A. P. Lightman, Robert P. Kirshner, Margaret J. Geller, Vera C. Rubin, Alan Guth, and James Gunn. The book is an excellent overview of the big questions facing modern cosmology. It does not require a background in physics, so any lay reader who appreciates astronomy and the study of the cosmos will enjoy this lively discussion.

This book, first published in 1991, tells the story of how astronomy and physics work together to unravel many mysteries of stars and nebulae. Stress is laid on a non-technical description of how an understanding of these objects is obtained, not on just a mere review of facts. After a succinct, non-mathematical excursion into the principles of radiation and atomic structure, the text explains in simple terms the physical processes at work in stars and gaseous nebulae. A survey of masses, dimensions, luminosities, temperatures and chemical composition of stars is followed by an exploration of their interiors and how stars generate energy. An account of the exciting new field of high energy astronomy and the origin of cosmic rays is given at the end of the book. This is the ideal introduction for physics and astronomy students to the important field of modern astronomics. It should also appeal to amateur astronomers and the reader interested in the life history of a star.
