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
We are not alone. They are here. And there’s no going back. Perfect for fans of The Fifth Wave and the I Am Number Four series, Dark Energy is a thrilling stand-alone science fiction adventure from Robison Wells, critically acclaimed author of Variant and Blackout. Five days ago, a massive UFO crashed in the Midwest. Since then, nothing—or no one—has come out. If it were up to Alice, she’d be watching the fallout on the news. But her dad is director of special projects at NASA, so she’s been forced to enroll in a boarding school not far from the crash site. Alice is right in the middle of the action, but even she isn’t sure what to expect when the aliens finally emerge. Only one thing is clear: everything has changed.

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
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.

"Tamsin Kuhn Trakroo has just started studying at The Prometheus Institute, the world's most famous and prestigious science school. The Instittued is a futurristic wonderland filled iwth genius teachers and floating helper robots known as S.T.A.T.s. But Tamsin is stressed! Her dead father now lives as a hologram stored in Tamsin's galasses, and he keeps beckoning her to destroy the Insttute. Can she trust her weird holographic Dad? Not to mention Tamsin's really cute roommate, Garyn, just discovered a dangerous energy source that could win her the Prometheus Institute Award for Superior Science, or it could tear a hole in the very space/time continuum! In the ultimate school of science, it's not your friends, your teachers, or your family that you can trust. You can only trust in SCIENCE!"--

Book Description
Cosmic inflation and dark energy hold the key to the origin and the eventual fate of the Universe. Despite the increasing prominence of these subjects in research and teaching over the past decade or more, no introductory textbook dedicated to these topics has been previously published. Dr. Konstantinos Dimopoulos is a highly regarded expert in the field, and an experienced communicator of the subject to students. In this book, he provides advanced undergraduate and early graduate students with an accessible introduction and equips them with the tools they need to understand the cosmology of cosmic inflation and dark energy. Features: Provides a concise, pedagogical "crash course" in big bang cosmology, focusing on the dynamics and the history of the Universe, with an emphasis on the role of dark energy Chapters contain questions and problems for readers to test their understanding The first book to make cosmic inflation and dark energy accessible to students

Book Description
How Vera Rubin convinced the scientific community that dark matter might exist, persevering despite early dismissals of her work. We now know that the universe is mostly dark, made up of particles and forces that are undetectable even by our most powerful telescopes. The discovery of the possible existence of dark matter and dark energy signaled a Copernican-like revolution in astronomy: not only are we not the center of the universe, neither is the stuff of which we’re made. Astronomer Vera Rubin (1928–2016) played a pivotal role in this discovery. By showing that some astronomical objects seem to defy gravity’s grip, Rubin helped convince the scientific community of the possibility of dark matter. In Bright Galaxies, Dark Matter, and Beyond, Ashley Jean Yeager tells the story of Rubin’s life and work, recounting her persistence despite early dismissals of her work and widespread sexism in science. Yeager describes Rubin’s childhood fascination with stars, her education at Vassar and Cornell, and her marriage to a fellow scientist. At first, Rubin wasn’t taken seriously; she was a rarity, a woman in science, and her findings seemed almost incredible. Some observatories in midcentury America restricted women from using their large telescopes; Rubin was unable to collect her own data until a decade after she had earned her PhD. Still, she continued her groundbreaking work, driving a scientific revolution. She received the National Medal of Science in 1993, but never the Nobel Prize—perhaps overlooked because of her gender. She’s since been memorialized with a ridge on Mars, an asteroid, a galaxy, and most recently, the Vera C. Rubin Observatory—the first national observatory named after a woman.

Book Description
To the eyes of the average person and the trained scientist, the night sky is dark, even though the universe is populated by myriads of bright galaxies. Why this happens is a question commonly called Olbers' Paradox, and dates from at least 1823. How dark is the night sky is a question which preoccupies astrophysicists at the present. The answer to both questions tells us about the origin of the universe and the nature of its contents ? luminous galaxies like the Milky Way, plus the dark matter between them and the mysterious dark energy which appears to be pushing everything apart. In this book, the fascinating history of Olbers' Paradox is reviewed, and the intricate physics of the light/dark universe is examined in detail. The fact that the night sky is dark (a basic astronomical observation that anybody can make) turns out to be connected with the finite age of the universe, thereby confirming some event like the Big Bang. But the space between the galaxies is not perfectly black, and data on its murkiness at various wavelengths can be used to constrain and identify its unseen constituents.
