Wormhole Travel As Envisioned By Les Bossinas For NASA
A wormhole is a hypothetical structure that connects disparate points in spacetime. It can be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, different points in time, or both). Wormholes are based on a special Solutions of the Einstein field equations, solution of the Einstein field equations. More precisely they are a transcendental bijection of the spacetime continuum, an Asymptote, asymptotic projection of the Calabi–Yau manifold manifesting itself in anti-de Sitter space. Wormholes are consistent with the General relativity, general theory of relativity, but whether they actually exist is unknown. Many physicists postulate that wormholes are merely projections of a Four-dimensional space, fourth spatial dimension, analogous to how a two-dimensional (2D) being could experience only part of a three-dimensional (3D) object. In 1995, Matt Visser suggested there may be many wormholes in the universe if cosmic strings with negat ...

Language
Language is a structured system of communication that consists of grammar and vocabulary. It is the primary means by which humans convey meaning, both in spoken and signed language, signed forms, and may also be conveyed through writing system, writing. Human language is characterized by its cultural and historical diversity, with significant variations observed between cultures and across time. Human languages possess the properties of Productivity (linguistics), productivity and Displacement (linguistics), displacement, which enable the creation of an infinite number of sentences, and the ability to refer to objects, events, and ideas that are not immediately present in the discourse. The use of human language relies on social convention and is acquired through learning. Estimates of the number of human languages in the world vary between and . Precise estimates depend on an arbitrary distinction (dichotomy) established between languages and dialects. Natural languages are ...

Philosophical Fiction
Philosophical fiction is any fiction that devotes a significant portion of its content to the sort of questions addressed by philosophy. It might explore any facet of the human condition, including the function and role of society, the nature and motivation of human acts, the purpose of life, ethics or morals, the role of art in human lives, the role of experience or reason in the development of knowledge, whether there exists free will, or any other topic of philosophical interest. Philosophical fiction includes the ''novel of ideas'', which can also fall under the genre of science fiction, utopian and dystopian fiction, and bildungsroman. There is no universally accepted definition of philosophical fiction, but a sampling of notable works can help to outline its history. For example, a Platonic dialogue could be considered philosophical fiction. Some modern philosophers have written novels, plays, or short fiction in order to demonstrate or introduce their ideas. Common example ...

Multiverse
The multiverse is the hypothetical set of all universes. Together, these universes are presumed to comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called "parallel universes", "flat universes", "other universes", "alternate universes", "multiple universes", "plane universes", "parent and child universes", "many universes", or "many worlds". One common assumption is that the multiverse is a "patchwork quilt of separate universes all bound by the same laws of physics." The concept of multiple universes, or a multiverse, has been discussed throughout history. It has evolved and has been debated in various fields, including cosmology, physics, and philosophy. Some physicists have argued that the multiverse is a philosophical notion rather than a scientific hypothesis, as it cannot be empirically falsified. In recent years, there h ...

Parallel Universe (fiction)
A parallel universe, also known as an alternate universe, world, or dimension, is a plot device in fiction which uses the notion of a hypothetical universe co-existing with another, typically to enable alternative narrative possibilities. The sum of all potential parallel universes that constitute reality is often called the " multiverse". The device serves several narrative purposes. Among them, parallel universes have been used to allow stories with elements that would ordinarily violate the laws of nature, to enable characters to meet and interact with alternative versions of themselves or others from their home universe, thus enabling further character development, and to serve as a starting point for speculative fiction, particularly alternate history. History Early examples One of the first science-fiction examples of a parallel universe is Murray Leinster's short story '' Sidewise in Time'', published in 1934. Although Leinster's story was not the first example of ...

Weapons In Science Fiction
Strange and exotic weapons are a recurring feature in science fiction. In some cases, weapons first introduced in science fiction have been made a reality; other science-fiction weapons remain purely fictional, and are often beyond the realms of known physical possibility. At its most prosaic, science fiction features an endless variety of Sidearm (weapon), sidearms—mostly variations on real weapons such as guns and swords. Among the best-known of these are the List of weapons in Star Trek#Phasers, phaser—used in the ''Star Trek'' television series, films, and novels—and the lightsaber and List of Star Wars weapons#Personal ranged, blaster—featured in ''Star Wars'' movies, comics, novels, and TV shows. Besides adding action and entertainment value, weaponry in science fiction sometimes touches on deeper concerns and becomes a Theme (literary), theme, often motivated by contemporary issues. One example is science fiction that deals with weapons of mass destruction. In ear ...

Interstellar War
An interstellar war is a hypothetical space war between combatants from different planetary systems. The concept provides a common plot device in science fiction, especially in the space opera subgenre. In contrast, the term ''intergalactic war'' refers to war between combatants from different galaxies, and ''interplanetary war'' refers to war between combatants from different planets of the same planetary system. Likelihood Michael H. Hart argued that if humans ever spread to other planetary systems, the actual likelihood of interstellar war would be low due to the immense distances (and hence travel times involved)—interstellar war would require a vastly greater investment of time and resources than present-day intraplanetary wars involve. By contrast, Robert Freitas argued that the energy expenditure required for interstellar war would be trivial from the viewpoint of a Type II or Type III civilisation on the Kardashev scale. Interstellar war in fiction The earlie ...

Military Science Fiction
Military science fiction is a subgenre of science fiction and military fiction that depicts the use of science fiction technology, including spaceships and science fiction weapons, weapons, for military purposes and usually principal characters who are members of a military organization, usually during a war; occurring sometimes in outer space or on a different planet or planets. It exists in a range of media, including literature, comics, film, television and video games. A detailed description of the conflict, belligerents (which may involve extraterrestrials), tactics and weapons used for it, and the role of a military service and the individual members of that military organization form the basis for a typical work of military science fiction. The stories often use features of actual past or current Earth conflicts, with countries being replaced by planets or galaxies with similar characteristics, battleships replaced by space battleships, small arms and artillery replaced b ...

Universal Translator
A universal translator is a device common to many science fiction works, especially on television. First described in Murray Leinster's 1945 novella " First Contact", the translator's purpose is to offer an instant translation of any language. As a convention, it is used to remove the problem of translating between alien languages when it is not vital to the plot. Especially in science fiction television, translating a new language in every episode when a new species is encountered would consume time normally allotted for plot development and would potentially become repetitive to the point of annoyance. Occasionally, intelligent alien races are portrayed as being able to extrapolate the rules of English from little speech and rapidly become fluent in it, making the translator unnecessary. While a ''universal'' translator seems unlikely, scientists continue to work towards similar real-world technologies involving small numbers of known languages. General As a rule, a universa ...

The Languages Of Pao
''The Languages of Pao'' is a science fiction novel by American writer Jack Vance, first published in 1958, based on the Sapir–Whorf hypothesis, which asserts that a language's structure and grammar construct the perception and consciousness of its speakers. In the novel, the placid people from the planet Pao rely on other planets for technological innovations and manufactured goods and they do not resist when an invading force occupies the land and levies heavy taxes. To expel the aggressors and make the planet more independent, three new languages are introduced. A scientific language induces its speakers to innovate more; a well-ordered language encourages its speakers to be industrious; and a warlike language induces competitiveness and aggression. The new languages change the culture and Pao ousts their overlords and develops a sophisticated modern economy. A shorter version was published in '' Satellite Science Fiction'' in late 1957. After the Avalon Books hardcover ap ...

Babel 17
''Babel-17'' is a 1966 science fiction novel by American writer Samuel R. Delany in which the Sapir–Whorf hypothesis (that language influences thought and perception) plays an important part. It was joint winner of the Nebula Award for Best Novel in 1967 (with ''Flowers for Algernon'') and was also nominated for the Hugo Award for Best Novel in 1967. Delany hoped to have ''Babel-17'' originally published as a single volume with the novella '' Empire Star'', but this did not happen until a 2001 reprint. Plot summary Babel-17 is a language that can be used as a weapon by enemy invaders during an interstellar war. Chinese starship captain, linguist, poet, and telepath Rydra Wong begins to learn the language. After several attacks have been made by the invaders who speak Babel-17, she soon realizes the potential of the language to change one's thought process and provide speakers with certain powers, and she is recruited by her government to discover how the enemy is infiltrating ...

Sapir–Whorf Hypothesis
Linguistic relativity asserts that language influences worldview or cognition. One form of linguistic relativity, linguistic determinism, regards peoples' languages as determining and influencing the scope of cultural perceptions of their surrounding world. Various colloquialisms refer to linguistic relativism: the Whorf hypothesis; the Sapir–Whorf hypothesis ( ); the Whorf-Sapir hypothesis; and Whorfianism. The hypothesis is in dispute, with many different variations throughout its history. The ''strong hypothesis'' of linguistic relativity, now referred to as linguistic determinism, is that language ''determines'' thought and that linguistic categories limit and restrict cognitive categories. This was a claim by some earlier linguists pre-World War II; (a debate between university professors) since then it has fallen out of acceptance by contemporary linguists. Nevertheless, research has produced positive empirical evidence supporting a ''weaker'' version of linguistic rel ...
