An accessible introduction to modern physics that focuses on wormholes and discusses among other topics their structure, stability, dynamics, operation as time machines, utility as portals to parallel universes, and their implications for the distant future of humanity. Read the wormhole FAQ and the bullet point "principles" scattered throughout to quickly absorb the basics of wormhole physics. Go back and read the interstitial material for greater depth. Written by a physicist with years of experience in gently introducing physics to the mathematically challenged, it also covers the history of wormhole physics and delineates the unsolved problems at the forefront of research.
To create the exotic materials and technologies needed to make stargates and warp drives is the holy grail of advanced propulsion. A less ambitious, but nonetheless revolutionary, goal is finding a way to accelerate a spaceship without having to lug along a gargantuan reservoir of fuel that you blow out a tailpipe. Tethers and solar sails are conventional realizations of the basic idea. There may now be a way to achieve these lofty objectives. “Making Starships and Stargates” will have three parts. The first will deal with information about the theories of relativity needed to understand the predictions of the effects that make possible the “propulsion” techniques, and an explanation of those techniques. The second will deal with experimental investigations into the feasibility of the predicted effects; that is, do the effects exist and can they be applied to propulsion? The third part of the book – the most speculative – will examine the question: what physics is needed if we are to make wormholes and warp drives? Is such physics plausible? And how might we go about actually building such devices? This book pulls all of that material together from various sources, updates and revises it, and presents it in a coherent form so that those interested will be able to find everything of relevance all in one place.
The story of an elite team of scientists and soldiers who travel to other worlds through an alien-built portal, Stargate SG-1 gave its viewers a weekly dose of spectacle and high adventure. Over its ten-season run (1997-2007), the series explored the interactions of the scientific and military cultures represented by its characters, as well as the place of science in society. The initial airing of Stargate SG-1 coincided with the “Science Wars,” a highly public clash among scholars and public intellectuals over the nature and value of scientific knowledge. Critics of science argued that it was merely one form of knowledge among many, subject to biases and blind spots imposed by the culture in which it was created. Defenders of science—mostly scientists themselves—contended that it possessed a unique ability to uncover universal truths, and thus was uniquely valuable to society. In Science Wars through the Stargate: Explorations of Science and Society in Stargate SG-1, Steven Gil offers the first in-depth analysis of the series and places it in the context of contemporary debates about the nature of scientific thought. Gil contends that representations of science within SG-1 can be more fully understood through the prism of the Science Wars. Scientific ideas put forth in SG-1 demonstrate how such complex intellectual exchanges and debates have a place in popular culture and can be further understood through these fictional articulations. Although SG-1 serves as the principal case study, the analysis also casts light on the role and position of science in science fiction television more generally. The long-form narrative of Stargate SG-1 enabled it to engage, in sophisticated ways, with many of the questions at issue in the Science Wars. As the author illustrates, the show presented a complex, sophisticated portrait of science and scientists at a time when the scientific enterprise was under intense public scrutiny. Science Wars through the Stargate will be of interest to science fiction scholars and fans of the series, but also to those interested in the public’s evolving understanding of science and its role in society.
How does the Star Trek universe stack up against the real universe? What warps when you're traveling at warp speed? What is the difference between a wormhole and a black hole? Are time loops really possible, and can I kill my grandmother before I am born? Anyone who has ever wondered "could this really happen?" will gain useful insights into the Star Trek universe (and, incidentally, the real world of physics) in this charming and accessible guide. Lawrence M. Krauss boldly goes where Star Trek has gone-and beyond. From Newton to Hawking, from Einstein to Feynman, from Kirk to Picard, Krauss leads readers on a voyage to the world of physics as we now know it and as it might one day be.

This book uses the knowledge of physics to interpret the events and facts in the Universe from a completely different perspective as philosophically. In a way, this is a philosophy for physic with a different Universe model proposal. It proposes some answers for the mechanism of motion in the perspective of Speed, momentum, relativistic mass, mass existence, inertia, time dilation, length contraction by using Waveform Time due to expansion of the Universe. In this view, you can see the mechanism of time dilation and length contraction in the quantum level under constant speed and acceleration. The book also suggests some explanations for The Time, The Dimension, the 4th and 5th dimensions, The Anti Matter, The Spin, The Bonds, The Chaotic Systems. And the Book gives some answers in the same viewpoint for the impossibility of traveling in Time and reaching Light Speed for the Mass.
NEW SPACE OPERA FROM MULTIPLE NEBULA- AND HUGO-WINNING AUTHOR NANCY KRESS WHAT LIES BEYOND THE ELEVENTH GATE . . . Despite economic and territorial tensions, no one wants the city-states of the Eight Worlds to repeat the Terran Collapse by going to war. But when war accidentally happens, everyone seeks ways to exploit it for gain. The Landry and Peregoy ruling dynasties see opportunities to grab territory, increase profits, and settle old scores. Exploited underclasses use war to fuel rebellion. Ambitious heirs can finally topple their elders’ regimes—or try to. But the unexpected key to either victory or peace lies with two persons uninterested in conquest, profits, or power. Philip Anderson seeks only the transcendent meaning of the physics underlying the universe. Tara Landry, spoiled and defiant youngest granddaughter of dynasty head Rachel Landry, accidentally discovers an eleventh star-jump gate, with a fabulous find on the planet behind it. Her discovery, and Philip’s use of it, alter everything for the Eight Worlds. At the publisher's request, this title is sold without DRM (Digital Rights Management).

The Remarkable Life of U.S. Government Remote Viewer 001 Joseph McMoneagle is now known as the best Operational Remote Viewer in the history of the U.S. Army's Special Project-Stargate. His intelligence collection results have never been surpassed and rarely equaled. Among his achievements: He described the interior of a top-secret Soviet manufacturing plant and accurately predicted a new class of submarine under construction there. He sketched the location and described the thoughts of a kidnapped U.S. Army General being held by the Red Brigade in Northern Italy. Nearly a year in advance he accurately predicted when Skylab would leave orbit and where it would impact on the Earth's surface. After conventional reconnaissance failed, he and others were able to locate a downed Soviet bomber that had been carrying nuclear materials. He achieved these results using scientifically designed and tested double-blind protocols. And in the years since his retirement he has continued to demonstrate these abilities on camera for national television in three countries, in the lab at the famed Monroe Institute, and for private companies. Are his abilities a natural gift, or taught? Was it his largely unsuspected psychic ability that helped keep him alive in Vietnam, and aided in his invaluable contributions to the cold war effort, that made McMoneagle a first-class remote viewer? How much did he owe to his near-death experience in the 1970s? And why would he give up a safe and distinguished career as an advisor to the Commanding General of the U.S. Army Intelligence and Security Command to become Remote Viewer 001? This is his story."
