Black Holes, Wormholes and Time Machines


Book Description

Bringing the material up to date, Black Holes, Wormholes and Time Machines, Second Edition captures the new ideas and discoveries made in physics since the publication of the best-selling first edition. While retaining the popular format and style of its predecessor, this edition explores the latest developments in high-energy astroparticle physics




Black Holes and Time Warps


Book Description

In this masterfully written and brilliantly informed work, Dr. Rhorne, the Feynman Professor of Theoretical Physics at Caltech, leads readers through an elegant, always human, tapestry of interlocking themes, answering the great question: what principles control our universe and why do physicists think they know what they know? Features an introduction by Stephen Hawking.







Black Holes, Cosmology And Extra Dimensions (Second Edition)


Book Description

Assuming basic knowledge of special and general relativity, this book guides the reader to problems under consideration in modern research, concerning black holes, wormholes, cosmology, and extra dimensions. Its first part is devoted to local strong field configurations (black holes and wormholes) in general relativity and its most relevant extensions: scalar-tensor, f(R), and multidimensional theories. The second part discusses cosmology, including inflation and problems of a unified description of the whole evolution of the universe. The third part concerns multidimensional theories of gravity and contains a number of original results obtained by the authors. Expository work is conducted for a mechanism of symmetries and fundamental constants formation. The original approach to nonlinear multidimensional gravity that is able to construct a unique perspective describing different phenomena is highlighted.Much of the content was previously presented only in journal publications and is new for book contents, e.g., on regular black holes, various scalar field solutions, wormholes and their stability, inflation, clusters of primordial black holes, and multidimensional gravity. The last two topics are added in this new edition of the book. The other chapters are also updated to include new discoveries like the detection of gravitational waves.




How to Build a Time Machine


Book Description

Inspired at an impressionable age by the work of science fiction writers H.G.Wells and Arthur C Clarke, Paul Davies has thought long and hard about ways to travel in time. Here, the best-selling popular science writer finally reveals how it can be done - without breaking the laws of physics and without causing any earth-shattering paradoxes. Since time is money, time travel is a costly business. But with the help of a handy black hole, or better a wormhole, and a bit of luck, Davies's guide illustrates how this new mode of travel could yet be a viable option.

Black Holes, Wormholes and Time Machines


Book Description

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.




So You Created a Wormhole


Book Description

Welcome, intrepid temporal explorers, to the world's first and only field manual/survival guide to time travel!DON'T LEAVE THIS TIME PERIOD WITHOUT IT! Humans from H. G. Wells to Albert Einstein to Bill & Ted have been fascinated by time travel-some say drawn to it like moths to a flame. But in order to travel safely and effectively, newbie travelers need to know the dos and don'ts. Think of this handy little book as the only thing standing between you and an unimaginably horrible death-or being trapped forever in another time or alternate reality. You get: Essential time travel knowledge: Choosing the right time machine, from DeLoreans to hot tubs to phone booths-and beyond What to say-and what NOT to say-to your doppelganger Understanding black holes and Stephen Hawking's term "spaghettification" (no, it's not a method of food preperation; yes, it is a horrifically painful way to meet your end) The connection between Einstein's General Theory of Relativity, traversing wormholes and the 88 mph speed requirement The possible consequences of creating a time paradox-including, but not limited to, the implosion of the universe Survival tips for nearly any sticky time travel situation: How to befriend a dinosaur and subsequently fight other dinosaurs with that dinosaur Instructions to build your very own Rube Goldberg Time Machine Crusading-for fun and profit Tips on battling cowboys, pirates, ninjas, samurai, Nazis, Vikings, robots and space marines How to operate a microwave oven Enjoying the servitude of robots and tips for living underground when they inevitably rise up against us

Notes for a New Physics


Book Description

This is the second edition, with changes and additions, of a book proposed about two years ago. For the layman, modern physics is like an immense and magnificent cathedral that is impressive in its complex and sophisticated architecture, and amazing in size and richness of the workmanship. Yet, in this apparently almost complete edifice, there is no answer to a long series of basic and crucial questions, while in any case these answers are indispensable and preliminary to any general theory. It is essential to avoid the confusion between appropriate and clarifying answers and false tautological answers or formulas that actually say nothing about the questions posed. In this book, the starting point is the interpretation given by Einstein’s general relativity to explain the gravitational force not as an action at a distance but as an effect intrinsic to the deformation of space caused by a “mass”. This interpretation is extended to the explanation of any attractive or repulsive force as an effect of flattening of dimensions with positive or negative curvature, one for each force. It offers, without any forcing, an explanation for most of the unsolved questions of physics, of the nature of a mass, matter and antimatter, of the structure of an atom, of the origin of natural constants, of the quantization of phenomena, etc. It also offers a different interpretation of the nature of electrons and black holes. Furthermore, the existence of antimatter in protons, but not in neutrons, is also predicted, a phenomenon that appears to be documented by recent works. This book is not written by a physicist but it is also highlighted why a professional physicist would have to overcome serious or insurmountable difficulties to give innovative answers to the fundamental unsolved problems of physics using concepts unrelated to those currently accepted.




Lorentzian Wormholes


Book Description

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.
