"An account of the century of experimentation that confirmed Einstein's theory of relativity, bringing to life the science and scientists at the origins of relativity, the development of radio telescopes, the discovery of black holes and quasars, and the still unresolved place of gravity in quantum theory. Albert Einstein did nothing of note on May 29, 1919, yet that is when he became immortal. On that day, astronomer Arthur Eddington and his team observed a solar eclipse and found something extraordinary: gravity bends light, just as Einstein predicted. The findings confirmed the theory of general relativity, fundamentally changing our understanding of space and time. A century later, another group of astronomers is performing a similar experiment on a much larger scale. The Event Horizon Telescope, a globe-spanning array of radio dishes, is examining space surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way. As Ron Cowen recounts, one foremost goal of the experiment is to determine whether Einstein was right on the details. Gravity lies at the heart of what we don't know about quantum mechanics, but tantalizing possibilities for deeper insight are offered by black holes. By observing starlight wrapping around Sagittarius A*, the telescope will not only provide the first direct view of an event horizon--a black hole's point of no return--but will also enable scientists to test Einstein's theory under the most extreme conditions. Gravity's Century shows how we got from the pivotal observations of the 1919 eclipse to the Event Horizon Telescope, and what is at stake today. Breaking down the physics in clear and approachable language, Cowen makes vivid how the quest to understand gravity is really the quest to comprehend the universe."--

Ron Cowen offers a sweeping account of the century of experimentation that has consistently confirmed Einstein’s general theory of relativity. He shows how we got from Eddington’s pivotal observations of the 1919 eclipse to the Event Horizon Telescope, aimed at starlight wrapping around the black hole at our galaxy’s center.

In theory, at least, gravitational waves do exist. We are constantly bathed in gravitational radiation, which is generated when stars explode or collide and a portion of their mass becomes energy that ripples out like a disturbance on the surface of a serene pond. But unfortunately no gravitational wave has ever been directly detected even though the search has lasted more than forty years. As the leading chronicler of the search for gravitational waves, Harry Collins has been right there with the scientists since the start. The result of his unprecedented access to the front lines of physical science is Gravity’s Ghost, a thrilling chronicle of high-stakes research and cutting-edge discovery. Here, Collins reveals that scientific discovery and nondiscovery can turn on scientific traditions and rivalries, that ideal statistical analysis rests on impossible procedures and unattainable knowledge, and that fact in one place is baseless assumption in another. He also argues that sciences like gravitational wave detection, in exemplifying how the intractable is to be handled, can offer scientific leadership a moral beacon for the twenty-first century. In the end, Gravity’s Ghost shows that discoveries are the denouements of dramatic scientific mysteries.

The author of this history of mankind’s increasingly successful attempts to understand, to measure and to map the Earth’s gravity field (commonly known as ‘little g’ or just ‘g’) has been following in the footsteps of the pioneers, intermittently and with a variety of objectives, for more than fifty years. It is a story that begins with Galileo’s early experiments with pendulums and falling bodies, progresses through the conflicts between Hooke and Newton and culminates in the measurements that are now being made from aircraft and satellites. The spectacular increases in accuracy that have been achieved during this period provide the context, but the main focus is on the people, many of whom were notable eccentrics. Also covered are the reasons WHY these people thought their measurements would be useful, with emphasis in the later chapters on the place of ‘g’ in today’s applied geology, and on the ways in which it is providing new and spectacular visions of our planet. It is also, in part, a personal memoir that explores the parallels between the way fieldwork is being done now and the difficulties that accompanied its execution in the past. Selected topics in the mathematics of ‘g’ are discussed in a series of short Codas.

"What we know always leads to what we do not know. This book follows the historical path of the most brilliant theories in physics, and the people who made them: the general theory of relativity and quantum field theory. The paths of these very successful descriptions of the Universe intersect. When the two theories collide, the light that they shed on the understanding of our world is extinguished. We do not know the road ahead. Can they be merged into a single theory? Nobody has an answer yet. Where are the clues? In theory, experiments, mathematics, or cosmology? Is the most important physics question of our time too difficult, or is the answer already growing in the mind of a young woman or man somewhere in the world?"--Book jacket.

The headlong rush, the rapid montage, the soaring superhero, the plunging roller coaster—Matters of Gravity focuses on the experience of technological spectacle in American popular culture over the past century. In these essays, leading media and cultural theorist Scott Bukatman reveals how popular culture tames the threats posed by technology and urban modernity by immersing people in delirious kinetic environments like those traversed by Plastic Man, Superman, and the careening astronauts of 2001: A Space Odyssey and The Right Stuff. He argues that as advanced technologies have proliferated, popular culture has turned the attendant fear of instability into the thrill of topsy-turvydom, often by presenting images and experiences of weightless escape from controlled space. Considering theme parks, cyberspace, cinematic special effects, superhero comics, and musical films, Matters of Gravity highlights phenomena that make technology spectacular, permit unfettered flights of fantasy, and free us momentarily from the weight of gravity and history, of past and present. Bukatman delves into the dynamic ways pop culture imagines that apotheosis of modernity: the urban metropolis. He points to two genres, musical films and superhero comics, that turn the city into a unique site of transformative power. Leaping in single bounds from lively descriptions to sharp theoretical insights, Matters of Gravity is a deft, exhilarating celebration of the liberatory effects of popular culture.

‘Gravity, a Geometrical Course’ presents general relativity (GR) in a systematic and exhaustive way, covering three aspects that are homogenized into a single texture: i) the mathematical, geometrical foundations, exposed in a self consistent contemporary formalism, ii) the main physical, astrophysical and cosmological applications, updated to the issues of contemporary research and observations, with glimpses on supergravity and superstring theory, iii) the historical development of scientific ideas underlying both the birth of general relativity and its subsequent evolution. The book is divided in two volumes. Volume Two is covers black holes, cosmology and an introduction to supergravity. The aim of this volume is two-fold. It completes the presentation of GR and it introduces the reader to theory of gravitation beyond GR, which is supergravity. Starting with a short history of the black hole concept, the book covers the Kruskal extension of the Schwarzschild metric, the causal structures of Lorentzian manifolds, Penrose diagrams and a detailed analysis of the Kerr-Newman metric. An extensive historical account of the development of modern cosmology is followed by a detailed presentation of its mathematical structure, including non-isotropic cosmologies and billiards, de Sitter space and inflationary scenarios, perturbation theory and anisotropies of the Cosmic Microwave Background. The last three chapters deal with the mathematical and conceptual foundations of supergravity in the frame of free differential algebras. Branes are presented both as classical solutions of the bulk theory and as world-volume gauge theories with particular emphasis on the geometrical interpretation of kappa-supersymmetry. The rich bestiary of special geometries underlying supergravity lagrangians is presented, followed by a chapter providing glances on the equally rich collection of special solutions of supergravity. Pietro Frè is Professor of Theoretical Physics at the University of Torino, Italy and is currently serving as Scientific Counsellor of the Italian Embassy in Moscow. His scientific passion lies in supergravity and all allied topics, since the inception of the field, in 1976. He was professor at SISSA, worked in the USA and at CERN. He has taught General Relativity for 15 years. He has previously two scientific monographs, “Supergravity and Superstrings” and “The N=2 Wonderland”, He is also the author of a popular science book on cosmology and two novels, in Italian.

Imagine a straight line tunnel right through the Earth connecting two cities, and a train falling through it. This is a Gravity train, and it has been a frequent example in physics books for more than a century. But could such a system actually be built? What new technological breakthroughs would be required? How has tunnel technology evolved during the industrial age so far? Francis Graham (Kent State University) examines this and the prospects of the future high technology required for it in this book, which takes an optimistic look at the future development of human society.
