Book Description
From Pulitzer Prize nominee Lawrence Weschler, a fascinating profile of Walter Murch, a film legend and amateur astrophysicist whose investigations could reshape our understanding of the universe. For film aficionados, Walter Murch is legendary--a three-time Academy Award winner, arguably the most admired sound and film editor in the world for his work on Apocalypse Now, The Godfather trilogy, The English Patient, and many others. Outside of the studio, his mind is wide-ranging; his passion, pursued for several decades, has been astrophysics, in particular the rehabilitation of Titius-Bode, a long-discredited 18th century theory regarding the patterns by which planets and moons array themselves in gravitational systems across the universe. Though as a consummate outsider he's had a hard time attracting any sort of comprehensive hearing from professional astrophysicists, Murch has made advances that even some of them find intriguing, including a connection between Titius Bode and earlier notions--going back past Kepler and Pythagorus--of musical harmony in the heavens. Unfazed by rejection, ever probing, Murch perseveres in the highest traditions of outsider science. Lawrence Weschler brings Murch's quest alive in all its seemingly quixotic, yet still plausible, splendor, probing the basis for how we know what we know, and who gets to say. "The wholesale rejection of alternative theories has repeatedly held back the progress of vital science," Weschler observes, citing early twentieth-century German amateur Alfred Wegener, whose speculations about continental drift were ridiculed at first, only to be accepted as fact decades later. Theoretical physicist Lee Smolin says "It is controversy that brings science alive"--and Murch's quest does that in spades. His fascination with the way the planets and their moons are arranged opens up the field of celestial mechanics for general readers, sparking an awareness of the vast and (to us) invisible forces constantly at play in the universe.

Book Description
This book brings together reviews from leading international authorities on the developments in the study of dark matter and dark energy, as seen from both their cosmological and particle physics side. Studying the physical and astrophysical properties of the dark components of our Universe is a crucial step towards the ultimate goal of unveiling their nature. The work developed from a doctoral school sponsored by the Italian Society of General Relativity and Gravitation. The book starts with a concise introduction to the standard cosmological model, as well as with a presentation of the theory of linear perturbations around a homogeneous and isotropic background. It covers the particle physics and cosmological aspects of dark matter and (dynamical) dark energy, including a discussion of how modified theories of gravity could provide a possible candidate for dark energy. A detailed presentation is also given of the possible ways of testing the theory in terms of cosmic microwave background, galaxy redshift surveys and weak gravitational lensing observations. Included is a chapter reviewing extensively the direct and indirect methods of detection of the hypothetical dark matter particles. Also included is a self-contained introduction to the techniques and most important results of numerical (e.g. N-body) simulations in cosmology. " This volume will be useful to researchers, PhD and graduate students in Astrophysics, Cosmology Physics and Mathematics, who are interested in cosmology, dark matter and dark energy.

Book Description
'Clear and compact ... It's hard to fault as a brief, easily digestible introduction to some of the biggest questions in the Universe' Giles Sparrow, BBC Four's The Sky at Night , Best astronomy and space books of 2019: 5/5 All the matter and light we can see in the universe makes up a trivial 5 per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That 'something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets. By the 1990s we also knew that the expansion of the universe was accelerating. Something, named dark energy, is pushing it to expand faster and faster. Across the universe, this requires enough energy that the equivalent mass would be nearly fourteen times greater than all the visible material in existence. Brian Clegg explains this major conundrum in modern science and looks at how scientists are beginning to find solutions to it.

Book Description
A Seminary Co-op Notable Book A BBC Sky at Night Best Book “An impressively comprehensive bird’s-eye view of a research topic that is both many decades established and yet still at the very cutting edge of astronomy and physics.” —Katie Mack, Wall Street Journal “Schilling has craftily combined his lucid and accessible descriptions of science with the personal story of those unlocking the finer details of the missing mass mystery. The result is enthralling...A captivating scientific thriller.” —BBC Sky at Night “Fascinating...A thorough and sometimes troubling account of the hunt for dark matter...You will come away with a very good understanding of how the universe works. Well, our universe, anyway.” —Michael Brooks, New Scientist When you train a telescope on outer space, you can see luminous galaxies, nebulae, stars, and planets. But if you add all that together, it constitutes only 15 percent of the matter in the universe. Despite decades of research, the nature of the remaining 85 percent is unknown. We call it dark matter. Physicists have devised huge, sensitive instruments to search for dark matter, which may be unlike anything else in the cosmos—some unknown elementary particle. Yet so far dark matter has escaped every experiment. It is so elusive that some scientists are beginning to suspect there might be something wrong with our theories about gravity or with the current paradigms of cosmology. Govert Schilling interviews believers and heretics and paints a colorful picture of the history and current status of dark matter research. The Elephant in the Universe is a vivid tale of scientists puzzling their way toward the true nature of the universe.

Book Description
The origin and evolution of the primordial perturbation is the key to understanding structure formation in the earliest stages of the Universe. It carries clues to the types of physical phenomena active in that extreme high-density environment. Through its evolution, generating first the observed cosmic microwave background anisotropies and later the distribution of galaxies and dark matter in the Universe, it probes the properties and dynamics of the present Universe. This graduate-level textbook gives a thorough account of theoretical cosmology and perturbations in the early Universe, describing their observational consequences and showing how to relate such observations to primordial physical processes, particularly cosmological inflation. With ambitious observational programmes complementing ever-increasing sophistication in theoretical modelling, cosmological studies will remain at the cutting edge of astrophysical studies for the foreseeable future.

Book Description
The authoritative story of the headline-making discovery of gravitational waves—by an eminent theoretical astrophysicist and award-winning writer. From the author of How the Universe Got Its Spots and A Madman Dreams of Turing Machines, the epic story of the scientific campaign to record the soundtrack of our universe. Black holes are dark. That is their essence. When black holes collide, they will do so unilluminated. Yet the black hole collision is an event more powerful than any since the origin of the universe. The profusion of energy will emanate as waves in the shape of spacetime: gravitational waves. No telescope will ever record the event; instead, the only evidence would be the sound of spacetime ringing. In 1916, Einstein predicted the existence of gravitational waves, his top priority after he proposed his theory of curved spacetime. One century later, we are recording the first sounds from space, the soundtrack to accompany astronomy’s silent movie. In Black Hole Blues and Other Songs from Outer Space, Janna Levin recounts the fascinating story of the obsessions, the aspirations, and the trials of the scientists who embarked on an arduous, fifty-year endeavor to capture these elusive waves. An experimental ambition that began as an amusing thought experiment, a mad idea, became the object of fixation for the original architects—Rai Weiss, Kip Thorne, and Ron Drever. Striving to make the ambition a reality, the original three gradually accumulated an international team of hundreds. As this book was written, two massive instruments of remarkably delicate sensitivity were brought to advanced capability. As the book draws to a close, five decades after the experimental ambition began, the team races to intercept a wisp of a sound with two colossal machines, hoping to succeed in time for the centenary of Einstein’s most radical idea. Janna Levin’s absorbing account of the surprises, disappointments, achievements, and risks in this unfolding story offers a portrait of modern science that is unlike anything we’ve seen before.
