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.

This book was released on 2018-05-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the past 20 years causality violations and superluminal motion have been the object of intensive study as physical and geometrical phenomena. This book compiles the results of its author and also reviews other work in the field. In particular, the following popular questions are addressed: Is causality protected by quantum divergence at the relevant Cauchy horizon? How much "exotic matter" would it take to create a time machine or a warp drive? What is the difference between a "discovered" time machine and a created one? Why does a time traveler fail to kill their grandfather? How should we define the speed of gravity and what is its magnitude?

Download or read book Time Travel in Einstein s Universe written by J. Richard Gott and published by HMH. This book was released on 2015-08-25 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Princeton astrophysicist explores whether journeying to the past or future is scientifically possible in this “intriguing” volume (Neil deGrasse Tyson). It was H. G. Wells who coined the term “time machine”—but the concept of time travel, both forward and backward, has always provoked fascination and yearning. It has mostly been dismissed as an impossibility in the world of physics; yet theories posited by Einstein, and advanced by scientists including Stephen Hawking and Kip Thorne, suggest that the phenomenon could actually occur. Building on these ideas, J. Richard Gott, a professor who has written on the subject for Scientific American, Time, and other publications, describes how travel to the future is not only possible but has already happened—and contemplates whether travel to the past is also conceivable. This look at the surprising facts behind the science fiction of time travel “deserves the attention of anyone wanting wider intellectual horizons” (Booklist). “Impressively clear language. Practical tips for chrononauts on their options for travel and the contingencies to prepare for make everything sound bizarrely plausible. Gott clearly enjoys his subject and his excitement and humor are contagious; this book is a delight to read.” —Publishers Weekly
Download or read book Frontiers of Propulsion Science written by Marc G. Millis and published by AIAA (American Institute of Aeronautics & Astronautics). This book was released on 2009 with total page 786 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frontiers of Propulsion Science is the first-ever compilation of emerging science relevant to such notions as space drives, warp drives, gravity control, and faster-than-light travel - the kind of breakthroughs that would revolutionize spaceflight and enable human voyages to other star systems. Although these concepts might sound like science fiction, they are appearing in growing numbers in reputable scientific journals. This is a nascent field where a variety of concepts and issues are being explored in the scientific literature, beginning in about the early 1990s. The collective status is still in step 1 and 2 of the scientific method, with initial observations being made and initial hypotheses being formulated, but a small number of approaches are already at step 4, with experiments underway. This emerging science, combined with the realization that rockets are fundamentally inadequate for interstellar exploration, led NASA to support the Breakthrough Propulsion Physics Project from 1996 through 2002.""Frontiers of Propulsion Science"" covers that project as well as other related work, so as to provide managers, scientists, engineers, and graduate students with enough starting material that they can comprehend the status of this research and decide if and how to pursue it in more depth themselves. Five major sections are included in the book: Understanding the Problem lays the groundwork for the technical details to follow; Propulsion Without Rockets discusses space drives and gravity control, both in general terms and with specific examples; Faster-Than-Light Travel starts with a review of the known relativistic limits, followed by the faster-than-light implications from both general relativity and quantum physics; Energy Considerations deals with spacecraft power systems and summarizes the limits of technology based on accrued science; and, From This Point Forward offers suggestions for how to manage and conduct research on such visionary topics.

Download or read book How to Build a Time Machine written by Paul Davies and published by Penguin. This book was released on 2003-03-25 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: With his unique knack for making cutting-edge theoretical science effortlessly accessible, world-renowned physicist Paul Davies now tackles an issue that has boggled minds for centuries: Is time travel possible? The answer, insists Davies, is definitely yes—once you iron out a few kinks in the space-time continuum. With tongue placed firmly in cheek, Davies explains the theoretical physics that make visiting the future and revisiting the past possible, then proceeds to lay out a four-stage process for assembling a time machine and making it work. Wildly inventive and theoretically sound, How to Build a Time Machine is creative science at its best—illuminating, entertaining, and thought provoking.
Download or read book Nuclear Time Travel and the Alien Mind written by Anton Bernd Schmeikal and published by Nova Science Publishers. This book was released on 2018 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the unfunded opportunities (UFOs), like the TR3B or TR6, are already flying; with this in mind, it may appear that this book is published too late. However, this is not the case. Both extraterrestrials and humans have developed craft of similar a "planform". Officials and the media continuously feed the masses incorrect information. Drive technology of the honestly endeavoring "human" is outdated. It seems to have been copied from some ancient Indian scriptures. Indeed, electrostatic, electromagnetic and rotating plasma drives deliver fermionic power, but they are far from allowing humanity to harness the power of a hyperspace jump. In 2017, NASA ensured us that "for the near future, [a] warp drive remains a dream". As a matter of fact, both human and extraterrestrial humanoids have hypothesized the use anti-gravity, warping and time travelling vehicles, even what they call "living vessels". However, both have no theory, no theoretical foundations for nuclear time travel technology. This book delivers a few necessary basics concerning the possible future where this nuclear time travel could potentially become a reality.

As the daughter of a time traveler, Nix has spent sixteen years sweeping across the globe and through the centuries aboard her father’s ship. Modern-day New York City, nineteenth-century Hawaii, other lands seen only in myth and legend—Nix has been to them all. But when her father gambles with her very existence, it all may be about to end. Rae Carson meets Outlander in this epic debut fantasy. If there is a map, Nix’s father can sail his ship, The Temptation, to any place and any time. But now that he’s uncovered the one map he’s always sought—1868 Honolulu, the year before Nix’s mother died in childbirth—Nix’s life, her entire existence, is at stake. No one knows what will happen if her father changes the past. It could erase Nix’s future, her dreams, her adventures . . . her connection with the charming Persian thief, Kash, who’s been part of their crew for two years.
Download or read book Metamaterial Multiverse written by Igor I Smolyaninov and published by Morgan & Claypool Publishers. This book was released on 2018-11-29 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many physical properties of our universe, such as the relative strength of the fundamental interactions, the value of the cosmological constant, etc., appear to be fine-tuned for existence of human life. One possible explanation of this fine tuning assumes existence of a multiverse, which consists of a very large number of individual universes having different physical properties. Intelligent observers populate only a small subset of these universes, which are fine-tuned for life. In this book we will review several interesting metamaterial systems, which capture many features of important cosmological models and offer insights into the physics of many other non-trivial spacetime geometries, such as microscopic black holes, closed time-like curves (CTCs) and the Alcubierre warp drive.

Download or read book Warp Speed written by Travis Taylor and published by Baen. This book was released on 2006-05-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dr. Neal Anson Clemons, brilliant physicist and martial arts expert, was born at the very moment that men first landed on the moon, and his dream had always been to find a way to travel to the stars. And now he and his team have achieved a breakthrough, both in building a warp drive, and finding a new energy source powerful enough to make the drive more than an interesting theoretical concept. With the help of a beautiful Air Force Major and astronaut, Tabitha Ames, the US Government has funded the project, including assembly in orbit of the first faster-than-light probe. Unfortunately, forces working behind the scenes have much darker dreams, and they do not hesitate to blow up a space shuttle, attempt to kill Neal and Tabitha, and use the stolen warp technology to start what they expect to be a short victorious war with the United States. But Neal has ideas for using warp drive completely unsuspected by America's enemies, and repelling the all-out attack is only the beginning of a titanic struggle to reach the stars.
Download or read book Beyond Star Trek written by Lawrence M. Krauss and published by Harper Collins. This book was released on 2011-04-05 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the bestselling The Physics of Star Trek, the renowned theoretical physicist Lawrence Krauss took readers on an entertaining and eye-opening tour of the Star Trek universe to see how it stacked up against the real universe. Now, responding to requests for more as well as to a number of recent exciting discoveries in physics and astronomy, Krauss takes a provocative look at how the laws of physics relate to notions from our popular culture -- not only Star Trek, but other films, shows, and popular lore -- from Independence Day to Star Wars to The X-Files. What's the difference between a flying saucer and a flying pretzel? Why didn't the aliens in Independence Day have to bother invading Earth to destroy it? What's new with warp drives? What's the most likely scenario for doomsday? Are ESP and telekinesis impossible? What do clairvoyance and time travel have in common? How might quantum mechanics ultimately affect the fate of life in the universe?
