Book Synopsis Lorentzian Wormholes by : Matt Visser
Download or read book Lorentzian Wormholes written by Matt Visser and published by American Institute of Physics. This book was released on 1995 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing on pivotal work by Einstein, Wheeler, Thorne, Hawking, and others, Matt Visser charts the development and current state of Lorentzian wormhole physics. Dr. Visser shows that by pushing established physical theories to their limits, it is possible to deduce the true physics of such exotica as wormholes and time travel. The physical framework he uses is derived from one of the major research frontiers of modern theoretical physics: quantum gravity the intersection of classical Einstein gravity and quantum field theory. About the Author Matt Visser is Research Assistant Professor at Washington University, St. Louis. He has lectured in the United States and abroad on topics including wormhole physics, time travel, and the chronology protection conjecture. He has conducted postdoctoral research at both the University of Southern California and at Los Alamos National Laboratory.

Book Synopsis Wormholes, Warp Drives and Energy Conditions by : Francisco S. N. Lobo
Download or read book Wormholes, Warp Drives and Energy Conditions written by Francisco S. N. Lobo and published by Springer. This book was released on 2017-05-16 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Top researchers in the field of gravitation present the state-of-the-art topics outlined in this book, ranging from the stability of rotating wormholes solutions supported by ghost scalar fields, modified gravity applied to wormholes, the study of novel semi-classical and nonlinear energy conditions, to the applications of quantum effects and the superluminal version of the warp drive in modified spacetime. Based on Einstein's field equations, this cutting-edge research area explores the more far-fetched theoretical outcomes of General Relativity and relates them to quantum field theory. This includes quantum energy inequalities, flux energy conditions, and wormhole curvature, and sheds light on not just the theoretical physics but also on the possible applications to warp drives and time travel. This book extensively explores the physical properties and characteristics of these 'exotic spacetimes,' describing in detail the general relativistic geometries that generate closed timelike curves.
Book Synopsis Black Holes, Wormholes and Time Machines by : Jim Al-Khalili
Download or read book Black Holes, Wormholes and Time Machines written by Jim Al-Khalili and published by CRC Press. This book was released on 2002-01-01 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Do you know: What might happen if you fall into a black hole? That the Universe does not have an edge? That the reason it gets dark at night is proof of the Big Bang? That cosmic particles time-travel through the atmosphere defying death? That our past, present and future might all coexist "out there"? With two remarkable ideas, Albert Einstein revolutionized our view of the Universe. His first was that nothing can travel faster than light-the ultimate speed limit. This simple fact leads to the unavoidable conclusion that space and time must be linked together forever as Spacetime. With his second monumental insight, Einstein showed how Spacetime is warped and stretched by the gravity of all objects in the Universe and even punctured by black holes. But such possible twisting of Spacetime allowed a magic not even Einstein could have imagined: time-travel. Theoretical physicist Jim Al-Khalili finally lays science fiction to rest as he opens up Einstein's Universe. Leading us gently and light-heartedly through the dizzying world of our space and time, he even gives us the recipe for a time machine, capable of taking us Back to the Future, to Alice's Wonderland, or on a trip with the Terminator.

Book excerpt: Do you believe that the world will end on December 21, 2012? Neither did astrophysics professor Ivan Peterson until he saw the irrefutable evidence before him. What started out as an ordinary day for Dr. Peterson quickly turned into a challenge to save the world. With heart-pounding intensity and challenges at every corner, Dr. Peterson must work with the U.S. Military, the President of the United States, a couple of friends, and a visitor from the future to try to save the Earth from destruction. With only days to go before December 21, 2012, and with no clear strategy to save the world from the myriad of possible destructive forces, Professor Peterson must try to prevent a catastrophe. Nothing is as it seems, and everything seems to happen at once. Ivan’s extensive education was no preparation for what he and the others must now face. Which force will destroy the Earth and its people fi rst: a hostile alien race or the increasingly tense nuclear countries of the world, all with their weapons ready to fi re at a moment’s notice?

Book Synopsis Encyclopedia of Distances by : Michel Marie Deza
Download or read book Encyclopedia of Distances written by Michel Marie Deza and published by Springer. This book was released on 2016-08-16 with total page 756 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 4-th edition of the leading reference volume on distance metrics is characterized by updated and rewritten sections on some items suggested by experts and readers, as well a general streamlining of content and the addition of essential new topics. Though the structure remains unchanged, the new edition also explores recent advances in the use of distances and metrics for e.g. generalized distances, probability theory, graph theory, coding theory, data analysis. New topics in the purely mathematical sections include e.g. the Vitanyi multiset-metric, algebraic point-conic distance, triangular ratio metric, Rossi-Hamming metric, Taneja distance, spectral semimetric between graphs, channel metrization, and Maryland bridge distance. The multidisciplinary sections have also been supplemented with new topics, including: dynamic time wrapping distance, memory distance, allometry, atmospheric depth, elliptic orbit distance, VLBI distance measurements, the astronomical system of units, and walkability distance. Leaving aside the practical questions that arise during the selection of a ‘good’ distance function, this work focuses on providing the research community with an invaluable comprehensive listing of the main available distances. As well as providing standalone introductions and definitions, the encyclopedia facilitates swift cross-referencing with easily navigable bold-faced textual links to core entries. In addition to distances themselves, the authors have collated numerous fascinating curiosities in their Who’s Who of metrics, including distance-related notions and paradigms that enable applied mathematicians in other sectors to deploy research tools that non-specialists justly view as arcane. In expanding access to these techniques, and in many cases enriching the context of distances themselves, this peerless volume is certain to stimulate fresh research.
