The Expanding Universe

This book explores the history of the discovery of the expanding universe, one of the most exciting exploits in astronomy.

An overview of modern cosmology, accessible to undergraduate students, with emphasis on physical foundations and relations to modern observations.

In this fascinating Very Short Introduction, popular science writer John Gribben tells the story of our growing understanding of galaxies, from the days before Galileo to our present-day observations of our many hundreds of millions of galactic neighbors. Not only are galaxies fascinating astronomical structures in themselves, but their study has revealed much of what we know today about the cosmos, providing a window on the Big Bang and the origins of the Universe. Gribben looks at our own "Milky Way" Galaxy in detail, from the different kinds of stars that are born within it, to the origins of its magnificent spiral structure. Perhaps most interesting, Gribben describes the many exciting discoveries have been made about our own galaxy and about those beyond: how a supermassive black hole lurks at the center of every galaxy, how enormous forces are released when galaxies collide, how distant galaxies provide a window on the early Universe, and how the formation of young galaxies shed needed light on the mysteries of Cold Dark Matter. John Gribbin is one of the best-known current popular science writers. His many books include the acclaimed The Universe: A Biography, In Search of Schrodinger's Cat, and Science: A History. He has written for many newspapers and regularly contributes to radio and television documentaries and debates, and also writes science fiction novels. He formerly worked for Nature and New Scientist and is presently a Visiting Fellow in Astronomy at the University of Sussex. 1. A Very Short Introduction 2. The Great Debate 3. Our Island 4.

This book analyses, with archival evidence, the three major changes to astronomers' theories between 1900 and 1931.

The story of Hubble and Humason is one for the ages—and in particular, the Cosmic Age. In this compelling book, science writer Ron Voller digs deep into how and why the two scientists continued to investigate their theory of universal expansion in the face of persistent doubt, contrary theories, and calamitous world events. The evolution of this dynamic duo’s tenuous friendship and professional partnership is in many ways as intriguing as their groundbreaking work on the evolution of the universe. The book therefore traces their lives from their childhoods into their burgeoning careers, revealing how a World War and their own personal differences stood in the way of initial cooperation. It then shows how despite all this, the two opposites eventually came together in the pursuit of something far greater than themselves. This grand story is inextricably interwoven with that of Albert Einstein, Willem de Sitter, and other great physicists of the era, all of whom took part in the staggering quest to make sense of the Big Bang and what followed. “Edwin Hubble has often been considered as an island of sorts—a lone wolf of astronomy. But Voller’s book shows otherwise, as he examines Milt Humason’s essential contributions to our understanding of the expanding universe.” - Daniel Lewis, Dibner Senior Curator, History of Science & Technology, The Huntington Library

Kinetic Theory in the Expanding Universe is a self-contained exposition of the applications of kinetic theory to basic problems in modern cosmology, such as the role of stable and unstable massive neutrinos and the theory of cosmological helium production. There has been rapid development of the theory of the origin and evolution of the universe in recent years, stimulated, in large part, by new observations and theories in astrophysics and particle physics. Bernstein takes a different approach and studies what can be concluded from the application of kinetic theory, and in particular the Boltzmann equation and its solutions, to cosmological problems. He begins with a brief survey of the necessary relativity, cosmodynamics, and kinetic theory, before going on to discuss specific problems, such as the role of stable and unstable massive neutrinos, electron-positron annihilation and the theory of cosomological helium production. The focus is in obtaining both a theoretical understanding and concrete numerical results.

The Hubble Space Telescope. No other telescope combines instant name recognition with the production of consistently spectacular images. Yet few people outside of the astronomy community realize that Hubble is now at the apex of its imaging capabilities. A collection of stunningly detailed pictures, made possible by the new Wide Field Camera 3, has yet to be incorporated into a popular-level book. Until now. Hubble's Universe will be the premier venue for the Hubble Telescope's most recent visual splendors. Bestselling astronomy writer Terence Dickinson showcases extraordinary late-breaking pictures, many of which have yet to receive wide distribution as news stories or in publications outside scientific papers, and presents a breathtaking portfolio drawn from an archive of over 500,000 existing Hubble images. The accompanying text balances accuracy with accessibility, Dickinson's hallmark. And thanks to the author's familiarity with Hubble's history and discoveries and his access to top Hubble scientists for insight and accuracy, the text includes facts and tidbits not found in any other book. Combined with hundreds of brilliant images, the clear, succinct and illuminating narrative brings to life the fascinating forces at work in the universe.
