In A Brief History of Black Holes, award-winning University of Oxford researcher Dr Becky Smethurst charts five hundred years of scientific breakthroughs in astronomy and astrophysics. Right now, you are orbiting a black hole. The Earth orbits the Sun, and the Sun orbits the centre of the Milky Way: a supermassive black hole, the strangest and most misunderstood phenomenon in the galaxy. In this cosmic tale of discovery, Dr Becky Smethurst takes us from the earliest observations of the universe and the collapse of massive stars, to the iconic first photographs of a black hole and her own published findings. She explains why black holes aren’t really ‘black’, that you never ever want to be ‘spaghettified’, how black holes are more like sofa cushions than hoovers and why, beyond the event horizon, the future is a direction in space rather than in time. Told with humour and wisdom, this captivating book describes the secrets behind the most profound questions about our universe – all hidden inside black holes.

Dive into a mind-bending exploration of the physics of black holes Black holes, predicted by Albert Einstein’s general theory of relativity more than a century ago, have long intrigued scientists and the public with their bizarre and fantastical properties. Although Einstein understood that black holes were mathematical solutions to his equations, he never accepted their physical reality—a viewpoint many shared. This all changed in the 1960s and 1970s, when a deeper conceptual understanding of black holes developed just as new observations revealed the existence of quasars and X-ray binary star systems, whose mysterious properties could be explained by the presence of black holes. Black holes have since been the subject of intense research—and the physics governing how they behave and affect their surroundings is stranger and more mind-bending than any fiction. After introducing the basics of the special and general theories of relativity, this book describes black holes both as astrophysical objects and theoretical “laboratories” in which physicists can test their understanding of gravitational, quantum, and thermal physics. From Schwarzschild black holes to rotating and colliding black holes, and from gravitational radiation to Hawking radiation and information loss, Steven Gubser and Frans Pretorius use creative thought experiments and analogies to explain their subject accessibly. They also describe the decades-long quest to observe the universe in gravitational waves, which recently resulted in the LIGO observatories’ detection of the distinctive gravitational wave “chirp” of two colliding black holes—the first direct observation of black holes’ existence. The Little Book of Black Holes takes readers deep into the mysterious heart of the subject, offering rare clarity of insight into the physics that makes black holes simple yet destructive manifestations of geometric destiny.

Download and read online ebook The Curious History of Relativity write by Jean Eisenstaedt. This book was released on 2018-06-05. The Curious History of Relativity available in PDF, EPUB and Kindle. Black holes may obliterate most things that come near them, but they saved the theory of general relativity. Einstein's theory was quickly accepted as the true theory of gravity after its publication in 1915, but soon took a back seat in physics to quantum mechanics and languished for decades on the blackboards of mathematicians. Not until the existence of black holes by Stephen Hawking and Roger Penrose in the 1960s, after Einstein's death, was the theory revived. Almost one hundred years after general relativity replaced Newton's theory of gravitation, The Curious History of Relativity tells the story of both events surrounding general relativity and the techniques employed by Einstein and the relativists to construct, develop, and understand his almost impenetrable theory. Jean Eisenstaedt, one of the world's leading experts on the subject, also discusses the theory's place in the evolution of twentieth-century physics. He describes the main stages in the development of general relativity: its beginnings, its strange crossing of the desert during Einstein's lifetime while under heated criticism, and its new life from the 1960s on, when it became vital to the understanding of black holes and the observation of exotic objects, and, eventually, to the discovery of the accelerating universe. We witness Einstein's construction of his theory, as well as the work of his fascinated, discouraged, and enthusiastic colleagues--physicists, mathematicians, and astronomers. Written with flair, The Curious History of Relativity poses--and answers--the difficult questions raised by Einstein's magnificent intellectual feat.

Download and read online ebook The Black Hole of Empire write by Partha Chatterjee. This book was released on 2012-04-08. The Black Hole of Empire available in PDF, EPUB and Kindle. When Siraj, the ruler of Bengal, overran the British settlement of Calcutta in 1756, he allegedly jailed 146 European prisoners overnight in a cramped prison. Of the group, 123 died of suffocation. While this episode was never independently confirmed, the story of "the black hole of Calcutta" was widely circulated and seen by the British public as an atrocity committed by savage colonial subjects. The Black Hole of Empire follows the ever-changing representations of this historical event and founding myth of the British Empire in India, from the eighteenth century to the present. Partha Chatterjee explores how a supposed tragedy paved the ideological foundations for the "civilizing" force of British imperial rule and territorial control in India. Chatterjee takes a close look at the justifications of modern empire by liberal thinkers, international lawyers, and conservative traditionalists, and examines the intellectual and political responses of the colonized, including those of Bengali nationalists. The two sides of empire's entwined history are brought together in the story of the Black Hole memorial: set up in Calcutta in 1760, demolished in 1821, restored by Lord Curzon in 1902, and removed in 1940 to a neglected churchyard. Challenging conventional truisms of imperial history, nationalist scholarship, and liberal visions of globalization, Chatterjee argues that empire is a necessary and continuing part of the history of the modern state.
