Download or read book Timelike Infinity written by Stephen Baxter and published by Hachette UK. This book was released on 2013-01-24 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Timelike Infinity: the strange region at the end of time where the Xeelee, owners of the universe, are waiting... The second novel in Stephen Baxter's Xeelee sequence. First there were good times: humankind reached glorious heights, even immortality. Then there were bad times: Earth was occupied by the faceless, brutal Qax. Immortality drugs were confiscated, the human spirit crushed. Earth became a vast factory for alient foodstuffs. Into this new dark age appears the end of a tunnel through time. Made from exotic matter, it is humanity's greatest engineering project in the pre-Qax era, where the other end of the tunnel remains anchored near Jupiter. When a small group of humans in a makeshift craft outwit the Qax to escape to the past through the tunnel, it is not to warn the people of Earth against the Qax, who are sure to follow them. For these men and women from the future are themselves dangerous fanatics in pursuit of their own bizarre quantum grail. Michael Poole, architect of the tunnel, must boldly confront the consequences of his genius.

Book excerpt: Michael Poole's wormholes constructed in the orbit of Jupiter had opened the galaxy to humankind. Then Poole tried looping a wormhole back on itself, tying a knot in space and ripping a hole in time. It worked. Too well. Poole was never seen again. Then from far in the future, from a time so distant that the stars themselves were dying embers, came an urgent SOS--and a promise. The universe was doomed, but humankind was not. Poole had stumbled upon an immense artifact, light-years across, fabricated from the very string of the cosmos. The universe had a door. And it was open...
Download or read book Flux written by Stephen Baxter and published by Hachette UK. This book was released on 2013-01-24 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Star humans were engineered to exist within the mantle of a star, mere tools of their Earth-evolved makers in a war against the Xeelee, owners of the universe. Stephen Baxter's third novel in his magnificent Xeelee Sequence is an exotic and endearing story of an abandoned people. Abandoned to their fate, their history lost along with contact with their makers, Star people survive in an environment that is possibly the strangest in science fiction. Microscopic inhabitants of superfluid air above a Quantum Sea and below the tangled Crust of the Star, swimming in an electric-blue grid, the Magfield, which is subject to violent storms, Star people struggle, like us, to make sense of their world... and the threat hanging over it. Though the truth is far more disturbing and ominous than they feared, they will confront, finally, their makers, and they will rebel against the purpose for which they were created.
Download or read book Exact Space Times in Einstein s General Relativity written by Jerry B. Griffiths and published by Cambridge University Press. This book was released on 2009-10-15 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Einstein's theory of general relativity is a theory of gravity and, as in the earlier Newtonian theory, much can be learnt about the character of gravitation and its effects by investigating particular idealised examples. This book describes the basic solutions of Einstein's equations with a particular emphasis on what they mean, both geometrically and physically. Concepts such as big bang and big crunch-types of singularities, different kinds of horizons and gravitational waves, are described in the context of the particular space-times in which they naturally arise. These notions are initially introduced using the most simple and symmetric cases. Various important coordinate forms of each solution are presented, thus enabling the global structure of the corresponding space-time and its other properties to be analysed. The book is an invaluable resource both for graduate students and academic researchers working in gravitational physics.
Download or read book Raft written by Stephen Baxter and published by Hachette UK. This book was released on 2013-01-24 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stephen Baxter's highly acclaimed first novel and the beginning of his stunning Xeelee Sequence finally enters the SF Masterwork series! A spaceship from Earth accidentally crossed through a hole in space-time to a universe where the force of gravity is one billion times as strong as the gravity we know. Somehow the crew survived, aided by the fact that they emerged into a cloud of gas surrounding a black hole, which provided a breathable atmosphere. Five hundred years later, their descendants still struggle for existence, divided into two main groups. The Miners live on the Belt, a ramshackle ring of dwellings orbiting the core of a dead star, which they excavate for raw materials. These can be traded for food from the Raft, a structure built from the wreckage of the ship, on which a small group of scientists preserve the ancient knowledge which makes survival possible. Rees is a Miner whose curiosity about his world makes him stow away on a flying tree - just one of the many strange local lifeforms - carrying trade between the Belt and the Raft. And what he finds will change his world...

Download or read book Xeelee Vengeance written by Stephen Baxter and published by Gollancz. This book was released on 2017-06-15 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Half a million years in the future, on a dead, war-ravaged world at the centre of the Galaxy, there is a mile-high statue of Michael Poole. Poole, born on Earth in the fourth millennium, was one of mankind's most influential heroes. He was not a warrior, not an emperor. He was an engineer, a builder of wormhole transit systems. But Poole's work would ultimately lead to a vast and destructive conflict, a million-year war between humanity and the enigmatic, powerful aliens known as the Xeelee. The Xeelee won, but at a huge cost. And, defeated in a greater war, the Xeelee eventually fled the universe. Most of them. A handful were left behind, equipped with time travel capabilities, their task to tidy up: to reorder history more to the Xeelee's liking. That million-year war with humankind was one blemish. It had to be erased. And in order to do that, a lone Xeelee was sent back in time to remove Michael Poole from history . . .
Download or read book Introduction to 3 1 Numerical Relativity written by Miguel Alcubierre and published by OUP Oxford. This book was released on 2008-04-10 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the modern field of 3+1 numerical relativity. The book has been written in a way as to be as self-contained as possible, and only assumes a basic knowledge of special relativity. Starting from a brief introduction to general relativity, it discusses the different concepts and tools necessary for the fully consistent numerical simulation of relativistic astrophysical systems, with strong and dynamical gravitational fields. Among the topics discussed in detail are the following: the initial data problem, hyperbolic reductions of the field equations, gauge conditions, the evolution of black hole space-times, relativistic hydrodynamics, gravitational wave extraction and numerical methods. There is also a final chapter with examples of some simple numerical space-times. The book is aimed at both graduate students and researchers in physics and astrophysics, and at those interested in relativistic astrophysics.

Download or read book A Relativist s Toolkit written by Eric Poisson and published by Cambridge University Press. This book was released on 2004-05-06 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 2004 textbook fills a gap in the literature on general relativity by providing the advanced student with practical tools for the computation of many physically interesting quantities. The context is provided by the mathematical theory of black holes, one of the most elegant, successful, and relevant applications of general relativity. Among the topics discussed are congruencies of timelike and null geodesics, the embedding of spacelike, timelike and null hypersurfaces in spacetime, and the Lagrangian and Hamiltonian formulations of general relativity. Although the book is self-contained, it is not meant to serve as an introduction to general relativity. Instead, it is meant to help the reader acquire advanced skills and become a competent researcher in relativity and gravitational physics. The primary readership consists of graduate students in gravitational physics. It will also be a useful reference for more seasoned researchers working in this field.
Download or read book Seminar on Differential Geometry AM 102 Volume 102 written by Shing-tung Yau and published by Princeton University Press. This book was released on 2016-03-02 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of papers constitutes a wide-ranging survey of recent developments in differential geometry and its interactions with other fields, especially partial differential equations and mathematical physics. This area of mathematics was the subject of a special program at the Institute for Advanced Study in Princeton during the academic year 1979-1980; the papers in this volume were contributed by the speakers in the sequence of seminars organized by Shing-Tung Yau for this program. Both survey articles and articles presenting new results are included. The articles on differential geometry and partial differential equations include a general survey article by the editor on the relationship of the two fields and more specialized articles on topics including harmonic mappings, isoperimetric and Poincaré inequalities, metrics with specified curvature properties, the Monge-Arnpere equation, L2 harmonic forms and cohomology, manifolds of positive curvature, isometric embedding, and Kraumlhler manifolds and metrics. The articles on differential geometry and mathematical physics cover such topics as renormalization, instantons, gauge fields and the Yang-Mills equation, nonlinear evolution equations, incompleteness of space-times, black holes, and quantum gravity. A feature of special interest is the inclusion of a list of more than one hundred unsolved research problems compiled by the editor with comments and bibliographical information.
Download or read book Black Holes written by Derek J. Raine and published by Imperial College Press. This book was released on 2010 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: This introduction to the fascinating subject of black holes fills a significant gap in the literature which exists between popular, non-mathematical expositions and advanced textbooks at the research level. It is designed for advanced undergraduates and first year postgraduates as a useful stepping-stone to the advanced literature. The book provides an accessible introduction to the exact solutions of Einstein's vacuum field equations describing spherical and axisymmetric (rotating) black holes. The geometry and physical properties of these spacetimes are explored through the motion of particles and light. The use of different coordinate systems, maximal extensions and Penrose diagrams is explained. The association of the surface area of a black hole with its entropy is discussed and it is shown that with the introduction of quantum mechanics black holes cease to be black and can radiate. This result allows black holes to satisfy the laws of thermodynamics and thus be consistent with the rest of physics. In this new edition the problems in each chapter have been revised and solutions are provided. The text has been expanded to include new material on wormholes and clarify various other issues.
