They infinitely warp space and time, allowing nothing to escape: not matter, not even light. They are stellar corpses that have crushed themselves into oblivion, seemingly suspending the traditional laws of physics. The Big bang may have peppered the universe with primordial black holes, as small as protons but as massive as mountains. The universe itself may be disappearing into the final black hole. Black holes (BHs) and their warping effect on spacetime are described, beginning with a discussion on stellar evolution that includes white dwarfs, supernovas and neutron stars. The structure of static, rotating, and electrically charged BHs are considered, as well as the general theory of relativity, quantum mechanics, the Einstein-Rosen bridge, and wormholes in spacetime. Attention is also given to gravitational lenses, various space geometries, quasars, Seyfert galaxies, supermassive black holes, the evaporation and particle emission of BHs, and primordial BHs, including their temperature and lifetime. The author's engrossing, non-technical explanations are enhanced by numerous illustrations.

    However, it is one of the basic principles of quantum theory, the most widely accepted explanation of the subatomic world - and one of the fascinating subjects dealt with in Equations of Eternity.

    G. Lord was becoming a teenager in Southern California and her mother was dying of cancer, Lord's father-an archetypal, remote, rocket engineer- disappeared into his work at the Jet Propulsion Laboratory in Pasadena, building the space probes of the Mariner Mars 69 mission. Thirty years later, Lord found herself reporting on the JPL, triggering childhood memories and a desire to revisit her past as a way of understanding the ethos of rocket science. Astro Turf is the brilliant result of her journey of discovery.Remembering her pain at her father's absence, yet intrigued by what he did, Lord captures him on the page as she recalls her own youthful, eccentric fascination with science and space exploration. Into her family's saga she weaves the story of the legendary JPL- examining the complexities of its cultural history, from its start in 1936 to the triumphant Mars landings in 2004. She illuminates its founder, Frank Malina, whose brilliance in rocketry was shadowed by a flirtation with communism, driving him from the country even as we welcomed Wernher von Braun and his Nazi colleagues. Lord's own love of science fiction becomes a lens through which she views a profound cultural shift in the male-dominated world of space. And in pursuing the cause of her father's absence she stumbles on a hidden guilt, understanding "the anguish his proud silence caused both him and me, and how rooted that silence was in the culture of engineering."As in her acclaimed book Forever Barbie, which demystified an icon of feminine culture, Lord brings her penetrating insight to bear on a bastion of American masculinity, opening our eyes in unexpected and memorable ways.

    Dark matter. These strange and invisible substances don't just sound mysterious: their unexpected appearance in the cosmic census is upending long-held notions about the nature of the Universe. Astronomers have long known that the Universe is expanding, but everything they could see indicated that gravity should be slowing this spread. Instead, it appears that the Universe is accelerating its expansion and that something stronger than gravity--dark energy--is at work. In Einstein's Telescope Evalyn Gates, a University of Chicago astrophysicist, transports us to the edge of contemporary science to explore the revolutionary tool that unlocks the secrets of these little-understood cosmic constituents. Based on Einstein's theory of general relativity, gravitational lensing, or "Einstein's Telescope," is enabling new discoveries that are taking us toward the next revolution in scientific thinking--one that may change forever our notions of where the Universe came from and where it is going.

Voices from the Moon is an utterly unique chronicle of these defining moments in human history.

    It was 1982, fourteen years after I had last set foot in Vietnam, and thirteen years after I returned to The World. I had a family and a career. I'd never written more than an occasional letter to the editor in my life. My twisted insides had spawned ulcers. The nightmares were more frequent. I needed to get Vietnam out into the open, but I couldn't talk about it. Not after all those years. Thus begins John Ketwig's powerful memoir of the Vietnam War. Now, over 15 years after its initial publication, Sourcebooks is proud to bring ...and a hard rain fell back into print in a newly updated edition, with a new introduction by the author and eight pages of never-before-published photographs. From the country roads of upstate New York to the jungles of Vietnam, and finally to the Vietnam Veterans Memorial in Washington, D.C., ...and a hard rain fell is a gripping and visceral account of one young man's struggle to make sense of his place in a world gone mad.

    From the months each of us spent suspended in the womb anticipating birth to the moments when we wait for sleep to transport us to other realities, we are always aware of gravity. In On Gravity, physicist A. Zee combines profound depth with incisive accessibility to take us on an original and compelling tour of Einstein's general theory of relativity.Inspired by Einstein's audacious suggestion that spacetime could ripple, Zee begins with the stunning discovery of gravity waves. He goes on to explain how gravity can be understood in comparison to other classical field theories, presents the idea of curved spacetime and the action principle, and explores cutting-edge topics, including black holes and Hawking radiation. Zee travels as far as the theory reaches, leaving us with tantalizing hints of the utterly unknown, from the intransigence of quantum gravity to the mysteries of dark matter and energy.Concise and precise, and infused with Zee's signature warmth and freshness of style, On Gravity opens a unique pathway to comprehending relativity and gaining deep insight into gravity, spacetime, and the workings of the universe.

    Now in paperback, The Neptune File is the first account of the dramatic events surrounding the discovery of the solar system's eighth planet, and the story of two men who were able to see on paper what astronomers looking through telescopes for 200 years did not.

    In the 14 billion years since, scientists have pointed their telescopes upward, peering outward in space and backward in time, developing and refining theories to explain the weird and wonderful phenomena they observed.Through these observations, we now understand concepts like the size of the universe (still expanding), the distance to the next-nearest star from earth (Alpha Centauri, 26 trillion miles) and what drives the formation of elements (nuclear fusion), planets and galaxies (gravity), and black holes (gravitational collapse). But are these cosmological questions definitively answered or is there more to discover?Oxford University astrophysicist and popular YouTube personality Dr. Becky Smethurst presents everything you need to know about the universe in 10 accessible and engaging lessons.In Space at the Speed of Light: The History of 14 Billion Years for People Short on Time, she guides you through fundamental questions, both answered and unanswered, posed by space scientists. Why does gravity matter? How do we know the big bang happened? What is dark matter? Do aliens exist? Why is the sky dark at night? If you have ever looked up at night and wondered how it all works, you will find answers - and many more questions - in this pocket-sized tour of the universe!

    With a foreword by ESA astronaut Tim Peake.Started at the Royal Institution (RI) in 1825 by Michael Faraday, the Christmas Lectures have been broadcast on television since the 1960s and have formed part of the British Christmas tradition for generations. First devised to attract young people to the magic of science through spectacular demonstrations, they are now watched by millions of people around the world every year.Drawing on the incredible archive at the RI, which is packed full of handwritten notebooks, photographs and transcripts, this book will focus on thirteen of the most captivating Lectures given at the RI on space and time, taking a look at what we thought we knew then and what has been discovered since.

    Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    After a desperate six weeks, the beleaguered citadel surrendered to the Mamluks, bringing an end to Christendom's two-hundred year adventure in the Middle East.In The Accursed Tower, Roger Crowley delivers a lively narrative of the lead-up to the siege and a vivid, blow-by-blow account of the climactic battle. Drawing on extant Arabic sources as well as untranslated Latin documents, he argues that Acre is notable for technical advances in military planning and siege warfare, and extraordinary for its individual heroism and savage slaughter. A gripping depiction of the crusader era told through its dramatic last moments, The Accursed Tower offers an essential new view on a crucial turning point in world history.
