Once we thought the universe was filled with shining stars, dust, planets, and galaxies. We now know that more than 98 percent of all matter in the universe is dark. It emits absolutely nothing yet bends space and time; keeps stars speeding around galaxies; and determines the fate of the universe. But dark matter is only part of the story. Scientists have recently discovered that the expansion of the universe is speeding up, driven by a mysterious commodity called dark energy. Depending on what dark matter and energy happen to be, our seemingly quiet universe could end its days in a Big Rip, tearing itself apart, or a Big Crunch, collapsing down to a universe the size of nothing, ready to be reincarnated in a Big Bang once again. For the general reader and armchair astronomer alike, Iain Nicolson’s fascinating account shows how our ideas about the nature and the content of the universe have developed. He highlights key discoveries, explains underlying concepts, and examines current thinking on dark matter and dark energy. He describes techniques that astronomers use to explore the remote recesses of the cosmos in their quest to understand its composition, evolution, and ultimate fate.

Download Gravitational-Wave Astronomy Book in PDF, ePub and Kindle
This book is an introduction to gravitational waves and related astrophysics. It provides a bridge across the range of astronomy, physics and cosmology that comes into play when trying to understand the gravitational-wave sky. Starting with Einstein's theory of gravity, chapters develop the key ideas step by step, leading up to the technology that finally caught these faint whispers from the distant universe. The second part of the book makes a direct connection with current research, introducing the relevant language and making the involved concepts less "mysterious". The book is intended to work as a platform, low enough that anyone with an elementary understanding of gravitational waves can scramble onto it, but at the same time high enough to connect readers with active research - and the many exciting discoveries that are happening right now. The first part of the book introduces the key ideas, following a general overview chapter and including a brief reminder of Einstein's theory. This part can be taught as a self-contained one semester course. The second part of the book is written to work as a collection of "set pieces" with core material that can be adapted to specific lectures and additional material that provide context and depth. A range of readers may find this book useful, including graduate students, astronomers looking for basic understanding of the gravitational-wave window to the universe, researchers analysing data from gravitational-wave detectors, and nuclear and particle physicists.

Download The Fabric of the Cosmos Book in PDF, ePub and Kindle
NATIONAL BESTSELLER • From one of the world’s leading physicists and author of the Pulitzer Prize finalist The Elegant Universe, comes “an astonishing ride” through the universe (The New York Times) that makes us look at reality in a completely different way. Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.

Download The Cosmic Cocktail Book in PDF, ePub and Kindle
The inside story of the epic quest to solve the mystery of dark matter The ordinary atoms that make up the known universe—from our bodies and the air we breathe to the planets and stars—constitute only 5 percent of all matter and energy in the cosmos. The rest is known as dark matter and dark energy, because their precise identities are unknown. The Cosmic Cocktail is the inside story of the epic quest to solve one of the most compelling enigmas of modern science—what is the universe made of?—told by one of today's foremost pioneers in the study of dark matter. Blending cutting-edge science with her own behind-the-scenes insights as a leading researcher in the field, acclaimed theoretical physicist Katherine Freese recounts the hunt for dark matter, from the discoveries of visionary scientists like Fritz Zwicky—the Swiss astronomer who coined the term "dark matter" in 1933—to the deluge of data today from underground laboratories, satellites in space, and the Large Hadron Collider. Theorists contend that dark matter consists of fundamental particles known as WIMPs, or weakly interacting massive particles. Billions of them pass through our bodies every second without us even realizing it, yet their gravitational pull is capable of whirling stars and gas at breakneck speeds around the centers of galaxies, and bending light from distant bright objects. Freese describes the larger-than-life characters and clashing personalities behind the race to identify these elusive particles. Many cosmologists believe we are on the verge of solving the mystery. The Cosmic Cocktail provides the foundation needed to fully fathom this epochal moment in humankind’s quest to understand the universe.

Download Dark Matter and the Dinosaurs Book in PDF, ePub and Kindle
In this brilliant exploration of our cosmic environment, the renowned particle physicist and New York Times bestselling author of Warped Passages and Knocking on Heaven’s Door uses her research into dark matter to illuminate the startling connections between the furthest reaches of space and life here on Earth. Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it might have been dark matter that killed the dinosaurs. Working through the background and consequences of this proposal, Randall shares with us the latest findings—established and speculative—regarding the nature and role of dark matter and the origin of the Universe, our galaxy, our Solar System, and life, along with the process by which scientists explore new concepts. In Dark Matter and the Dinosaurs, Randall tells a breathtaking story that weaves together the cosmos’ history and our own, illuminating the deep relationships that are critical to our world and the astonishing beauty inherent in the most familiar things.

Download The Light/dark Universe Book in PDF, ePub and Kindle
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.

Download The Dark Side of Modernity Book in PDF, ePub and Kindle
In this book, one of the world’s leading social theorists presents a critical, alarmed, but also nuanced understanding of the post-traditional world we inhabit today. Jeffrey Alexander writes about modernity as historical time and social condition, but also as ideology and utopia. The idea of modernity embodies the Enlightenment’s noble hopes for progress and rationality, but its reality brings great suffering and exposes the destructive impulses that continue to motivate humankind. Alexander examines how twentieth-century theorists struggled to comprehend the Janus-faced character of modernity, which looks backward and forward at the same time. Weber linked the triumph of worldly asceticism to liberating autonomy but also ruthless domination, describing flights from rationalization as systemic and dangerous. Simmel pointed to the otherness haunting modernity, even as he normalized the stranger. Eisenstadt celebrated Axial Age transcendence, but acknowledged its increasing capacity for barbarity. Parsons heralded American community, but ignored modernity’s fragmentations. Rather than seeking to resolve modernity’s contradictions, Alexander argues that social theory should accept its Janus-faced character. It is a dangerous delusion to think that modernity can eliminate evil. Civil inclusion and anti-civil exclusion are intertwined. Alexander enumerates dangerous frictions endemic to modernity, but he also suggests new lines of social amelioration and emotional repair.

In this dark and gripping sci-fi noir, an exiled police detective arrives at a lunar penal colony just as a psychotic android begins a murderous odyssey across the far side of the moon. Purgatory is the lawless moon colony of eccentric billionaire, Fletcher Brass: a mecca for war criminals, murderers, sex fiends, and adventurous tourists. You can’t find better drugs, cheaper plastic surgery, or a more ominous travel advisory anywhere in the universe. But trouble is brewing in Brass’s black-market heaven. When an exiled cop arrives in this wild new frontier, he immediately finds himself investigating a string of ruthless assassinations in which Brass himself—and his equally ambitious daughter—are the chief suspects. Meanwhile, two-thousand kilometers away, an amnesiac android, Leonardo Black, rampages across the lunar surface. Programmed with only the notorious “Brass Code”—a compendium of corporate laws that would make Ayn Rand blush—Black has only one goal in mind: to find Purgatory and conquer it. Visual, visceral, and tons of fun, The Dark Side fuses hard science with brutal crime and lunar adventure. It’s an intense, stylish, and action-packed thriller with a body count to match.
