Book excerpt: Meet the players in the most fundamental scientific revolution since Copernicus The Facts of Matter It is one of the most disturbing aspects of our universe: only four per cent of it consists of the matter that makes up every star, planet, and every book. The rest is completely unknown. Acclaimed science writer Richard Panek tells the story of the handful of scientists who have spent the past few decades on a quest to unlock the secrets of “dark matter” and the even stranger substance called “dark energy”. These are perhaps the greatest mysteries in science,and solving them will reshape our understanding of the universe and our place in it. The stakes could not be higher. Panek’s fast-paced narrative, filled with original, in-depth reporting and intimate, behind-the-scenes details, brings this epic story to life for the very first time.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The laws of thermodynamics drive everything that happens in the universe. From the sudden expansion of a cloud of gas to the cooling of hot metal, and from the unfurling of a leaf to the course of life itself - everything is directed and constrained by four simple laws. They establish fundamental concepts such as temperature and heat, and reveal the arrow of time and even the nature of energy itself. Peter Atkins' powerful and compelling introduction explains what the laws are and how they work, using accessible language and virtually no mathematics. Guiding the reader from the Zeroth Law to the Third Law, he introduces the fascinating concept of entropy, and how it not only explains why your desk tends to get messier, but also how its unstoppable rise constitutes the engine of the universe.

Book excerpt: Advances made by physicists in understanding matter, space, and time and by astronomers in understanding the universe as a whole have closely intertwined the question being asked about the universe at its two extremesâ€"the very large and the very small. This report identifies 11 key questions that have a good chance to be answered in the next decade. It urges that a new research strategy be created that brings to bear the techniques of both astronomy and sub-atomic physics in a cross-disciplinary way to address these questions. The report presents seven recommendations to facilitate the necessary research and development coordination. These recommendations identify key priorities for future scientific projects critical for realizing these scientific opportunities.

Book excerpt: 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 excerpt: “Splendidly satisfying reading, designed for a nonspecialist audience.”—Kirkus Reviews, starred review Evalyn Gates, a talented astrophysicist, transports readers to the edge of contemporary science to explore the revolutionary tool—”Einstein’s telescope”—that is unlocking the secrets of the Universe. Einstein’s telescope, or gravitational lensing, is so-called for the way gravity causes space to distort and allow massive objects to act like “lenses,” amplifying and distorting the images of objects behind them. By allowing for the detection of mass where no light is found, scientists can map out the distribution of dark matter and come a step closer to teasing out the effects of dark energy on the Universe—which may forever upend long-held notions about where the Universe came from and where it is going.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Intended for undergraduate non-science majors, satisfying a general education requirement or seeking an elective in natural science, this is a physics text, but with the emphasis on topics and applications in astronomy. The perspective is thus different from most undergraduate astronomy courses: rather than discussing what is known about the heavens, this text develops the principles of physics so as to illuminate what we see in the heavens. The fundamental principles governing the behaviour of matter and energy are thus used to study the solar system, the structure and evolution of stars, and the early universe. The first part of the book develops Newtonian mechanics towards an understanding of celestial mechanics, while chapters on electromagnetism and elementary quantum theory lay the foundation of the modern theory of the structure of matter and the role of radiation in the constitution of stars. Kinetic theory and nuclear physics provide the basis for a discussion of stellar structure and evolution, and an examination of red shifts and other observational data provide a basis for discussions of cosmology and cosmogony.
