Warp Drive
A warp drive or a drive enabling space warp is a fictional superluminal (faster than the speed of light) spacecraft propulsion system in many science fiction works, most notably ''Star Trek'', and a subject of ongoing real-life physics research. The general concept of "warp drive" was introduced by John W. Campbell in his 1957 novel '' Islands of Space'' and was popularized by the ''Star Trek'' series. Its closest real-life equivalent is the Alcubierre drive, a theoretical solution of the field equations of general relativity. History and characteristics Warp drive, or a drive enabling space warp, is one of several ways of travelling through space found in science fiction. It has been often discussed as being conceptually similar to hyperspace. A warp drive is a device that distorts the shape of the space-time continuum. A spacecraft equipped with a warp drive may travel at speeds greater than that of light by many orders of magnitude. In contrast to some other fictitious ...

Fredric Brown
Fredric Brown (October 29, 1906 – March 11, 1972) was an American science fiction, fantasy, and mystery writer.D. J. McReynolds, "The Short Fiction of Fredric Brown" in Frank N. Magill, (ed.) ''Survey of Science Fiction Literature'', Vol. 4. Englewood Cliffs, NJ: Salem Press, 1979. (pp. 1954–1957). He is known for his use of humor and for his mastery of the " short short" form—stories of one to three pages, often with ingenious plotting devices and surprise endings. Humor and a postmodern outlook carried over into his novels as well. One of his stories, " Arena", was adapted into to a 1967 episode of the American television series ''Star Trek''.

Tests Of Special Relativity
Special relativity is a physical theory that plays a fundamental role in the description of all physical phenomena, as long as gravitation is not significant. Many experiments played (and still play) an important role in its development and justification. The strength of the theory lies in its unique ability to correctly predict to high precision the outcome of an extremely diverse range of experiments. Repeats of many of those experiments are still being conducted with steadily increased precision, with modern experiments focusing on effects such as at the Planck scale and in the neutrino sector. Their results are consistent with the predictions of special relativity. Collections of various tests were given by Jakob Laub, Zhang, Mattingly, Clifford Will, and Roberts/Schleif. Special relativity is restricted to Minkowski space, flat spacetime, ''i.e.'', to all phenomena without significant influence of gravitation. The latter lies in the domain of general relativity and the correspon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Negative Mass
In theoretical physics, negative mass is a hypothetical type of exotic matter whose mass is of opposite sign to the mass of normal matter, e.g. −1 kg. Such matter would violate one or more energy conditions and exhibit strange properties such as the oppositely oriented acceleration for an applied force orientation. It is used in certain speculative hypothetical technologies such as time travel to the past and future, construction of traversable artificial wormholes, which may also allow for time travel, Krasnikov tubes, the Alcubierre drive, and potentially other types of faster-than-light warp drives. Currently, the closest known real representative of such exotic matter is a region of negative pressure density produced by the Casimir effect. In cosmology In December 2018, astrophysicist Jamie Farnes from the University of Oxford proposed a " dark fluid" theory, related, in part, to notions of gravitationally repulsive negative masses, presented earlier by Albert Ein ...

Anti-gravity
Anti-gravity (also known as non-gravitational field) is the phenomenon of creating a place or object that is free from the force of gravity. It does not refer to either the lack of weight under gravity experienced in free fall or orbit, or to balancing the force of gravity with some other force, such as electromagnetism or aerodynamic lift. Anti-gravity is a recurring concept in science fiction. "Anti-gravity" is often used to refer to devices that look as if they reverse gravity even though they operate through other means, such as lifters, which fly in the air by moving air with electromagnetic fields. Historical attempts at understanding gravity The possibility of creating anti-gravity depends upon a complete understanding and description of gravity and its interactions with other physical theories, such as general relativity and quantum mechanics; however, no quantum theory of gravity has yet been found. During the summer of 1666, Isaac Newton observed an apple falling fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Replicator (Star Trek)
In ''Star Trek'' a replicator is a machine that can create (and recycle) things. Replicators were originally seen to simply synthesize meals on demand, but in later series much larger non-food items appear. The technical aspects of replicated versus "real" things is sometimes a plot element. Origins and limitations Although previous sci-fi writers had speculated about the development of "replicating" or "duplicating" technology, the term "replicator" was not itself used until '' Star Trek: The Next Generation''. In simple terms, it was described as a 24th century advancement from the 23rd century "food synthesizer" seen in '' Star Trek: The Original Series''. In ''Star Trek: The Original Series'', food was created in various colored cubes. In '' Star Trek: The Animated Series'' (1974), various types of realistic-looking food could be requested, as in the episode entitled "The Practical Joker". The mechanics of these devices were never clearly explained on that show. The subsequ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teleportation
Teleportation is the hypothetical transfer of matter or energy from one point to another without traversing the physical space between them. It is a common subject in science fiction and fantasy literature. Teleportation is often paired with time travel, being that the traveling between the two points takes an unknown period of time, sometimes being immediate. An apport is a similar phenomenon featured in parapsychology and spiritualism. There is no known physical mechanism that would allow for teleportation. Some scientific papers and media articles describe "quantum teleportation", a scheme for quantum information transfer, which does not allow for faster-than-light communication. Etymology The use of the term ''teleport'' to describe the hypothetical movement of material objects between one place and another without physically traversing the distance between them has been documented as early as 1878. American writer Charles Fort is credited with having coined the wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubber Science
Rubber science is a science fiction term describing a quasi-scientific explanation for an aspect of a science fiction setting. Rubber science explanations are fictional but convincing enough to avoid upsetting the suspension of disbelief. Rubber science is a feature of most genres of science fiction, with the exception of hard science fiction. Coinage The term ''rubber science'' was coined by Norman Spinrad in his essay "Rubber Sciences", published in Reginald Bretnor's anthology ''The Craft of Science Fiction'' (1976). Rubber science was Spinrad's term for " pseudo-science ... made up by the writer with literary care that it not be discontinuous with the reader's realm of the possible." In "Rubber Sciences," Spinrad proposed eight rules of rubber science to write plausibly about future technology: #Explanations must feel scientifically correct and have internal consistency. #Principles used for plot purposes must be planted in the reader's mind long before they are used as plot ...

Photon
A photon () is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless particles that can move no faster than the speed of light measured in vacuum. The photon belongs to the class of boson particles. As with other elementary particles, photons are best explained by quantum mechanics and exhibit wave–particle duality, their behavior featuring properties of both waves and particles. The modern photon concept originated during the first two decades of the 20th century with the work of Albert Einstein, who built upon the research of Max Planck. While Planck was trying to explain how matter and electromagnetic radiation could be in thermal equilibrium with one another, he proposed that the energy stored within a material object should be regarded as composed of an integer number of discrete, equal-sized parts. To explain the pho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Special Relativity
In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between Spacetime, space and time. In Albert Einstein's 1905 paper, Annus Mirabilis papers#Special relativity, "On the Electrodynamics of Moving Bodies", the theory is presented as being based on just Postulates of special relativity, two postulates: # The laws of physics are Invariant (physics), invariant (identical) in all Inertial frame of reference, inertial frames of reference (that is, Frame of reference, frames of reference with no acceleration). This is known as the principle of relativity. # The speed of light in vacuum is the same for all observers, regardless of the motion of light source or observer. This is known as the principle of light constancy, or the principle of light speed invariance. The first postulate was first formulated by Galileo Galilei (see ''Galilean invariance'').

Lorentz Factor
The Lorentz factor or Lorentz term (also known as the gamma factor) is a dimensionless quantity expressing how much the measurements of time, length, and other physical properties change for an object while it moves. The expression appears in several equations in special relativity, and it arises in derivations of the Lorentz transformations. The name originates from its earlier appearance in Lorentz ether theory, Lorentzian electrodynamics – named after the Netherlands, Dutch physicist Hendrik Lorentz. It is generally denoted (the Greek lowercase letter gamma). Sometimes (especially in discussion of superluminal motion) the factor is written as (Greek uppercase-gamma) rather than . Definition The Lorentz factor is defined as \gamma = \frac = \frac = \frac , where: * is the relative velocity between inertial reference frames, * is the speed of light in vacuum, * is the ratio of to , * is coordinate time, * is the proper time for an observer (measuring time intervals in ...
