Offering a sweeping tour of fantastic physics and cosmic history, a view of the most fearsome places in the universe that finally asks what it will take to see the event horizon of a black hole.
We have long understood black holes to be the points at which the universe as we know it comes to an end - mysterious chasms so destructive and unforgiving that not even light can escape their deadly power. Recent research, however, has led to a cascade of new discoveries that have revealed an entirely new, and crucially important, side to black holes. Super-sized versions, often billions of times more massive than the Sun, lurk in every galaxy in the universe. And these chasms don't just vacuum up everything around them; they also spit out huge clouds of matter and energy. In Gravity's Engines, renowned astrophysicist Caleb Scharf reveals how these giant black holes profoundly rearrange the cosmos that surrounds them, controlling the number of stars in the galaxies and, in turn, the entire universe. With lucidity and elegance, Scharf traces the two hundred year history of our attempts to discover the nature of black holes, from an English academic turned clergyman in the late 1700's who first identified these 'dark stars' to Einstein and the great revolutions of relativity and quantum mechanics. Engaging with our deepest questions about our origins, he takes us on an intimate journey through our endlessly colourful universe, revealing how the cosmic capacity for life is ultimately governed by - and perhaps could not exist without - black holes.
Winner of the 1974 National Book Award "The most profound and accomplished American novel since the end of World War II." - The New Republic “A screaming comes across the sky. . .” A few months after the Germans’ secret V-2 rocket bombs begin falling on London, British Intelligence discovers that a map of the city pinpointing the sexual conquests of one Lieutenant Tyrone Slothrop, U.S. Army, corresponds identically to a map showing the V-2 impact sites. The implications of this discovery will launch Slothrop on an amazing journey across war-torn Europe, fleeing an international cabal of military-industrial superpowers, in search of the mysterious Rocket 00000.
This lavishly illustrated text, by two leading experts, presents all the current evidence for black holes and their cosmic context.
An Introduction to Gravity Modification, Second Edition is the result of a 12-year (1999-2011) study into the theoretical and technological feasibility of gravity modification, that presents the new physics of forces by replacing relativistic, quantum and string theories with process models. Gravity, electromagnetism and mechanical forces are unified by Ni fields, and obey a common equation g = (tau)c DEGREES2. Gravity modification is defined as the modification of the strength and direction of the gravitational acceleration without the use of mass as the primary source of this modification, in local space time. It consists of field modulation and field vectoring. Field modulation is the ability to attenuate or amplify a force field. Field vectoring is the ability to change the direction of this force field . This book reaches out to a wider audience, and not just to the theoretical physicist; to engineers and technologist who have the funding to experiment; just as Arno Penzias and Robert Woodrow Wilson experimented with the Holmdel Horn Antenna and discovered the microwave background radiation. The mathematics is easier than that taught in theoretical physics and therefore accessible to a wider audience such as these engineers and technolog
Electric propulsion systems for space vehicles must be able to restart and operate at zero and low gravity. This operation can be achieved if the tankage delivers only single-phase propellants. The requirements for feed systems of electric engines are described briefly. Also, the 1.85-second drop- test facility is described and the testing techniques are discussed. The minimum energy principle is presented along with a method for determining the direction of mass transfer in tapered tubes and liquid-vapor interface shapes in an annular space between concentric cylinders. Possible feed systems for electric engines are given, which utilize surface tension for fluid positioning and transfer. Zero-gravity and static-fluid configurations in cylindrical and spherical containers are discussed along with experimental observations. The interface 'overshoot' of the equilibrium zero-gravity configuration is also discussed.
This book investigates the literary imaginings of the postcolonial city through the lens of crime in texts set in Naples and Mumbai from the 1990s to the present. Employing the analogy of a ‘black hole,’ it posits the discourse on criminality as a way to investigate the contemporary spatial manifestations of coloniality and global capitalist urbanity. Despite their different histories, Mumbai and Naples have remarkable similarities. Both are port cities, ‘gateways’ to their countries and regional trade networks, and both are marked by extreme wealth and poverty. They are also the sites and symbolic battlegrounds for a wider struggle in which ‘the North exploits the South, and the South fights back.’ As one of the characters of the novel The Neapolitan Book of the Dead puts it, a narrativisation of the underworld allows for a ‘discovery of a different city from its forgotten corners.’ Crime provides a means to understand the relationship between space and society/culture in a number of cities across the Global South, by tracing a narrative of postcolonial urbanity that exposes the connections between exploitation and the ongoing ‘coloniality of power.’
On 14 September 2015, after 50 years of searching, gravitational waves were detected for the first time and astronomy changed for ever. Until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays and the rest. But gravitational waves – ripples in the fabric of space and time – are unrelenting, passing through barriers that stop light dead. At the two 4-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015 they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering. This was the first time black holes had ever been directly detected – and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a new, powerful path to understand the workings of the universe.
