SUPERANNO One of the most important unsolved problems of current physics, astronomy, and cosmology is the nature of dark matter and dark energy. These two invisible components of the universe seem to control the behavior of galaxies and the accelerating expansion of the universe, but we do not know what they are. The essential feature of Dark Matters, which sets it apart from all other such titles, is that it sees the whole universe as a tapestry. Original.

This book brings together process and postmodern theologians to reflect on the crucial topic of energy, asking: What are some of the connections between energy and theology? How do ideas about humanity and divinity interrelate with how we live our lives? Its contributors address energy in at least three distinct ways. First, in terms of physics, the discovery of dark energy in 1998 uncovered a mysterious force that seems to be driving the inflation of the universe. Here cosmology converges with theological reflection about the nature and origin of the universe. Second, the social and ecological contexts of energy use and the current energy crisis have theological implications insofar as they are caught up with ultimate human meanings and values. Finally, in more traditional theological terms of divine spiritual energy, we can ask how human conceptions of energy relate to divine energy in terms of creative power.

Most astronomers and physicists now believe that the matter content of the Universe is dominated by dark matter: hypothetical particles which interact with normal matter primarily through the force of gravity. Though invisible to current direct detection methods, dark matter can explain a variety of astronomical observations. This book describes how this theory has developed over the past 75 years, and why it is now a central feature of extragalactic astronomy and cosmology. Current attempts to directly detect dark matter locally are discussed, together with the implications for particle physics. The author comments on the sociology of these developments, demonstrating how and why scientists work and interact. Modified Newtonian Dynamics (MOND), the leading alternative to this theory, is also presented. This fascinating overview will interest cosmologists, astronomers and particle physicists. Mathematics is kept to a minimum, so the book can be understood by non-specialists.

Particles are the building blocks of the universe, shaping our very existence, as long as we view them as particles and not nebulous quantum objects For centuries, scientists have sought to discover and understand more about these particles, trying to unlock the secrets of how our universe was created and what will happen to it in the future, and thankfully we have now discovered a lot of answers in recent years. As an introduction to particle physics, which is aimed at physics undergraduates, this book discusses the range of quarks, leptons and bosons that we know or believe exist and the search for as yet undiscovered particles, including CERN's work on the Large Hadron Collider. The book also examines ways of testing whether or not an interaction would be possible or forbidden and also ways in which to identify unknown particles seen in a collision event. We also consider dark matter, what indicates that it exists and some possible candidates for it, and dark energy, the mysterious force that is actually causing the expansion of the universe to accelerate. David Chapple is a physicist who lectures in the OUDCE Department of the University of Oxford in particle physics, quantum physics and cosmology.

This book is a collection of fourteen essays that describe an inspiring journey through the universe and discusses popular science topics that modern physics and cosmology are struggling to deal with. What is our place in the universe and what happens in the magnificent cosmos where we exist for a brief amount of time. In an unique way that incorporates mythological and philosophical perspectives, the essays in this work address the big questions of what the universe is, how it came into being, and where it may be heading. This exciting adventure is a rich scientific history of elegant physics, mathematics, and cosmology as well as a philosophical and spiritual pursuit fueled by the human imagination.

An Introduction to Modern Cosmology Third Edition is an accessible account of modern cosmological ideas. The Big Bang Cosmology is explored, looking at its observational successes in explaining the expansion of the Universe, the existence and properties of the cosmic microwave background, and the origin of light elements in the universe. Properties of the very early Universe are also covered, including the motivation for a rapid period of expansion known as cosmological inflation. The third edition brings this established undergraduate textbook up-to-date with the rapidly evolving observational situation. This fully revised edition of a bestseller takes an approach which is grounded in physics with a logical flow of chapters leading the reader from basic ideas of the expansion described by the Friedman equations to some of the more advanced ideas about the early universe. It also incorporates up-to-date results from the Planck mission, which imaged the anisotropies of the Cosmic Microwave Background radiation over the whole sky. The Advanced Topic sections present subjects with more detailed mathematical approaches to give greater depth to discussions. Student problems with hints for solving them and numerical answers are embedded in the chapters to facilitate the reader’s understanding and learning. Cosmology is now part of the core in many degree programs. This current, clear and concise introductory text is relevant to a wide range of astronomy programs worldwide and is essential reading for undergraduates and Masters students, as well as anyone starting research in cosmology. Supplementary material, including full-colour images, updates and links for students and instructors, is available on the author’s website: http://www.roe.ac.uk/~arl/.

What's the meaning of it all? Or rather: what exactly is 'it'? Here Frank Wilczek, Nobel Prize-winning physicist and legend, examines the very nature of reality itself, showing how almost everything we think we know about 'it' is wrong. The Lightness of Being is an engaging tour de force, revealing a universe where matter is the hum of strange music, mass doesn't weigh, and empty space is a multilayered, multicoloured superconductor. Physicists' understanding of the essential nature of reality changed radically over the past quarter century. And Frank Wilczek has played a lead role in establishing the new paradigms. Transcending the clash and mismatch of older ideas about what matter and space is, Wilczek presents some brilliant and clear syntheses. Extraordinarily readable and authoritative, The Lightness of Being is the first book to unwrap these exciting new ideas for the general public. It explores their implications for basic questions about space, mass, energy, and the longed-for possibility of a fully unified theory of Nature. Pointing to new directions where great discoveries in fundamental physics are likely, and providing a visionary context for the experiments in CERN, he envisions a new Golden Age in physics.
