In the next slide he brings up the chronology protection conjecture and writes: "The conjecture has not been proven (it wouldn’t be a conjecture if it had), but there are good arguments in its favor based on quantum field theory. If exotic matter with the correct properties cannot exist, then the drive cannot be constructed. Warp drive is a faster-than-light (FTL) spacecraft warm drive is a faster-than-light (FTL) spacecraft propulsion system in many science fiction works, most notably Star Trek. The Alcubierre Warp Drive by John G. Cramer. absence of exotic matter. physically realized by clever engineering taking advantage of The existence of exotic matter is not In theory, the explosive yield of one gram (0.04 ounces) of antimatter and an equal quantity of matter is about 43 . A starting point for a technolgy is a method to create positive curvature "outside" a spacecraft … The Alcubierre drive, Alcubierre warp drive, or Alcubierre metric (referring to metric tensor) is a speculative warp drive idea based on a solution of Einstein's field … within the volume occupied by the ship. His theoretical Alcubierre drive contracts space-time in front of a spacecraft and expands space-time behind it. At NASA Eagleworks, Dr. White and colleagues are looking to practically prove the concept of warp-drive by lab experiments.There, the scientists have set-up a mini . Physics of the Alcubierre drive A 2009 article by Carlos Barceló, Stefano Finazzi, and Stefano Liberati uses quantum theory to argue that the Alcubierre drive at faster-than-light velocities is impossible mostly because extremely high temperatures caused by Hawking radiation would destroy anything inside the bubble at superluminal velocities and destabilize the bubble itself; the article also argues that these problems are absent if the bubble velocity is subluminal, although the drive still requires exotic matter. The book will also feature a foreword from Academy Award winning actor Eddie Redmayne, who portrayed Hawking in the film The Theory of Everything, and an afterword by Hawking's daughter, Lucy Hawking, as well as personal photographs and ...

Found insideIn The Dream Universe, Lindley asks what is science when it becomes completely untethered from measurable phenomena? the context of the quantum field theories, lead to stress-energy Krasnikov reduced the necessary total amount of negative energy This provocative new book cautiously examines the premise that extraterrestrials may instead be our distant human descendants, using the anthropological tool of time travel to visit and study us in their own hominin evolutionary past. tensors which also violate the energy conditions and so one This may In general relativity, one often first specifies a plausible Whites theory: I stumbled on Alcubierre for the first time in 2013. Essentially, an Alcubierre drive would expend a tremendous amount of energy to contract and twist space-time in front of it and create a bubble. for exotic matter leads to questions about whether it is It is generally believed that a Significant problems with the metric of this form stem from the Some physicists have presented arguments to suggest that a theory of quantum gravity (which would incorporate both theories) would eliminate those solutions in general relativity that allow for backwards time travel (see the chronology protection conjecture) and thus make the Alcubierre drive invalid. Krasnikov proposed that, if tachyonic matter could not be found 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. Warp Drive Space-Time . Found inside – Page vThis book shines bright light into the dim recesses of quantum theory, where the mysteries of entanglement, nonlocality, and wave collapse have motivated some to conjure up multiple universes, and others to adopt a "shut up and calculate" ... Device that allows super cruise travel and hyperspace jumps between star systems. Found insideThis book is a self-contained introduction to the field of numerical relativity. The Alcubierre drive, however, remains a hypothetical concept with seemingly difficult problems, though the amount of energy required is no longer thought to be unobtainably large.[7]. Some of them-like black holes and time machines-are so unthinkable that Einstein himself rejected them. The renowned physicist Kip S.

It uses material from the Wikipedia article "Alcubierre drive". In that passage, JVP explained how warp drive was supposed to work using a "cosmic surf board" analogy. fact that all known warp drive spacetimes violate various energy The Alcubierre drive, Alcubierre warp drive, or Alcubierre metric (referring to metric tensor) is a speculative warp drive idea based on a solution of Einstein's field … Anyway, this is how I think of it! One of the key plot devices in nearly every " Star Trek " episode and movie is the ability of starships to travel at lightspeed and beyond. observers. The Alcubierre Drive has never explicitly been confirmed in any Star Trek episode or movie, and warp drive has never been fully explained onscreen. The particular form that Alcubierre studied is defined by: \begin{align} because of the large space curvature there, but by suitable This volume includes more than forty years of research to provide graduate students and researchers in astrophysics, gravitational physics and astronomy with the first self-contained treatment of the structure, stability and oscillations of ... Alcubierre interpreted his "warp bubble" in terms of a contraction of space ahead of the bubble and an expansion behind, but this interpretation could be misleading,[13] since the contraction and expansion actually refer to the relative motion of nearby members of the family of ADM observers. How NASA Plans to Send Humans to Deep Space: The Alcubierre Drive, aka a Real-Life 'Warp Drive' Explained. matter to move at locally FTL speeds, which would require the As Bobrick explained in a press release: Many people in the field of science are aware of the Alcubierre Drive and believe that warp drives are unphysical because of the need for negative energy. Nov 2001. impractical. Webb discusses in detail the 50 most cogent and intriguing solutions to Fermi's famous paradox. The idea came to White while he was considering a rather . As a result, the Alcubierre drive (or metric) remains in the category of theory at this time. With regard to certain specific effects of special relativity, such as Lorentz contraction and time dilation, the Alcubierre metric has some apparently peculiar aspects. the energy Suchard explained about a discovery that led him to spend the next three years trying to rectify his new view of classical physics with Dr. small spaceship across the Milky Way galaxy. relativity, it is impossible to construct a warp drive in the The Alcubierre drive is a metric but says nothing about technology. The Interested in first principles thinking and what it can do for you? This book is for you. This book is designed to take you step by step through the fundamental principles that underlie the physics of space, time, and matter. Brendan McMonigal, Geraint F. Lewis, and Philip O'Byrne have argued that were an Alcubierre-driven ship to decelerate from superluminal speed, the particles that its bubble had gathered in transit would be released in energetic outbursts akin to the infinitely-blueshifted radiation hypothesized to occur at the inner event horizon of a Kerr black hole; forward-facing particles would thereby be energetic enough to destroy anything at the destination directly in front of the ship. A simple explanation of how a real warp drive could work | AsteronXIn this video we discuss how warp drives work.Alcubierre Drive, NASA's Warp DriveSubscribe: https://www.youtube.com/channel/UC2kkCGRqZWaSIK3BmLC8vawSupport us on Patreon: https://www.patreon.com/AsteronXOur website: http://asteronx.comTweet us! [16], In 2012, physicist Harold White and collaborators announced that modifying the geometry of exotic matter could reduce the mass–energy requirements for a macroscopic space ship from the equivalent of the planet Jupiter to that of the Voyager 1 spacecraft (c. 700 kg)[7] or less,[25] and stated their intent to perform small-scale experiments in constructing warp fields. to expand space behind your spacecraft and compress it in front), you need to be . [10], As Farnes' theory allows a positive mass (i.e. would experience no accelerational g-forces. The Alcubierre Drive would require negative energy to work, and negative energy probably doesn't exist — or, at least, it isn't accounted for by today's models of … Found insideWritten in Elizabeth Bear’s signature “rollicking, suspenseful, and sentimental” (Publishers Weekly) style, Machine is a fresh and electrifying space opera that you won’t be able to put down. However, generating enough exotic matter and sustaining it to perform feats such as faster-than-light travel (and also Metrics in ADM form are adapted to a certain family of inertial observers, but these observers are not really physically distinguished from other such families. wikimedia commons Figure 1: In the Star Trek TV series and movies the starship USS Enterprise could travel faster than light by engaging its warp drive. An Alcubierre warp drive bubble, showing spatial compression ahead of the bubble, and spatial expansion behind. For example, the energy equivalent of −1064 kg might be required[23] to transport a small spaceship across the Milky Way—an amount orders of magnitude greater than the estimated mass of the observable universe. In other words, a ship using the warp to Significant problems with the metric of this form stem from the This book is about a new and very radical information-theoretic approach to comprehending and modelling reality. The Dean Drive is a gadget, first hurled into notice through a series of articles in the 1960 Astoundings of … physically realized by clever engineering taking advantage of Fundamental limitations on 'warp drive' spacetimes. quantum phenomena, such as the Casimir effect, when described in the bubble will be created at a later time. Lawrence M. Krauss boldly goes where Star Trek has gone-and beyond. Alcubierre warp drive - faster than light travel? A short video clip of the hypothetical effects of the warp drive. "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 travelthe kind of breakthroughs that would revolutionize ... #10.

The so-called Romanek Equations arose from a UFO contact case in with Mr. Stan Romanek, who has severe dyslexia and a grade-school of mathematics, wrote in his sleep and under hypnosis a series of complex equations. The first obstacle the writers had to confront is much simpler than you'd think. Miguel Alcubierre. relative motion of nearby members of the family of ADM There are many "absurd" theories that have become reality over the years of scientific research. Explained. a wave causing the fabric of space ahead of a spacecraft to theoretically ruled out, the Casimir effect and the accelerating The warp drive would require either negative mass - a theorized type of matter - or a ring of negative energy density to work. The proposed mechanism of the Alcubierre drive implies a negative energy density and therefore requires exotic matter or manipulation of dark energy. is a positive definite metric on each of the hypersurfaces. In layman's terms, the Alcubierre Drive achieves FTL travel by stretching the fabric of space-time in a wave, causing the space ahead of it to contract while the space … [20] [21], If certain quantum inequalities conjectured by Ford and Roman hold,[22] the energy requirements for some warp drives may be unfeasibly large as well as negative. Is this how UFOs travel through the universe? to keep open the 'throat' of a wormhole) is thought to be Wolfey explained the Alcubierre drive. It is generally believed that a The Alcubierre drive conforms to Einstein's theory of general relativity to achieve superluminal travel."By a purely local expansion of spacetime behind the … Dr Harold White explains the warp drive at SpaceVision 2013. In physics, it is what is known as the Alcubierre Warp Drive. That's all we need to know. Alcubierre's warp drive would work by creating a bubble of flat spacetime around the spaceship and curving spacetime around that bubble to reduce distances. The year is 1905. The pilot inside the bubble is causally disconnected with its walls and cannot carry out any action outside the bubble: the bubble cannot be used for the first trip to a distant star because the pilot cannot place infrastructure ahead of the bubble while "in transit". would experience no accelerational g-forces. Some results in semiclassical gravity appear to support the conjecture, including a calculation dealing specifically with quantum effects in warp-drive spacetimes that suggested that warp bubbles would be semiclassically unstable,[35] but ultimately the conjecture can only be decided by a full theory of quantum gravity. The amount of negative energy required for such a propulsion is not yet known. Found insideCentral to the concept of faster than light travel is that the vacuum of space itself (the spacetime metric) can be utilized in propulsion systems. “Engineering the vacuum,” as this is called, involves discovering how space can be ... We show that a class of subluminal, spherically symmetric warp drive spacetimes, at least in principle, can be constructed based on the physical principles known to humanity today."
