Hyperspace
In science fiction, hyperspace (also known as nulspace, subspace, overspace, jumpspace and similar terms) is a concept relating to dimension#Additional dimensions, higher dimensions as well as parallel universes in fiction, parallel universes and a faster-than-light (FTL) method of interstellar travel. Its use in science fiction originated in the magazine ''Amazing Stories Quarterly'' in 1931 and within several decades it became one of the most popular Trope (literature), tropes of science fiction, popularized by its use in the works of authors such as Isaac Asimov and Edwin Charles Tubb, E. C. Tubb, and media franchises such as ''Star Wars''. One of the main reasons for the popularity of the concept is the prohibition against faster-than-light travel in ordinary space, which hyperspace allows writers to bypass. In most works, hyperspace is described as a higher dimension through which the shape of our three-dimensional space can be distorted to bring distant points close to ...

Parallel Universes In Fiction
A parallel universe, also known as a parallel dimension, alternate universe, or alternate reality, is a hypothetical self-contained plane of existence, co-existing with one's own. The sum of all potential parallel universes that constitute reality is often called a " multiverse". While the four terms are generally synonymous and can be used interchangeably in most cases, there is sometimes an additional connotation implied with the term "alternate universe/reality" that implies that the reality is a variant of our own, with some overlap with the similarly named alternate history. Fiction has long borrowed an idea of "another world" from myth, legend and religion. Heaven, Hell, Olympus, and Valhalla are all "alternative universes" different from the familiar material realm. Plato reflected deeply on the parallel realities, resulting in Platonism, in which the upper reality is perfect while the lower earthly reality is an imperfect shadow of the heavenly. The concept is also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dimension
In physics and mathematics, the dimension of a Space (mathematics), mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any Point (geometry), point within it. Thus, a Line (geometry), line has a dimension of one (1D) because only one coordinate is needed to specify a point on itfor example, the point at 5 on a number line. A Surface (mathematics), surface, such as the Boundary (mathematics), boundary of a Cylinder (geometry), cylinder or sphere, has a dimension of two (2D) because two coordinates are needed to specify a point on itfor example, both a latitude and longitude are required to locate a point on the surface of a sphere. A two-dimensional Euclidean space is a two-dimensional space on the Euclidean plane, plane. The inside of a cube, a cylinder or a sphere is three-dimensional (3D) because three coordinates are needed to locate a point within these spaces. In classical mechanics, space and time are different categ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Higher-dimensional Space

A two-dimensional Euclidean space is a two-dimensional space on the plane. The inside of a cube, a cylinder or a sphere is three-dimensional (3D) because three coordinates are needed to locate a point within these spaces. In classical mechanics, space and time are different categories and refer to absolute space and time. That conception of the world is a four-dimensional space but not the one that was found necessar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is evenly populated, and a couple of railroads run up and down the coasts of the largest continent. Earth sends secret agent Sam Tallon to Emm Luther to infiltrate the theocracy and extract the coordinates of the "null-space" (Hyperspace (science fiction), hyperspace) jump points of a newly discovered colonizable world, a closely guarded secret. When the religious secret police discover that he has false credentials and has entered their world under false pretenses, a frantic chase and flight ensues. He is captured in his hotel room. A high-ranking officer named Cherkassky tries to render Tallon harmless by erasing his memory of the jump data, using a device called a "brain brush".

Bob Shaw
Robert Shaw (31 December 1931 – 11 February 1996) was a science fiction writer and fan from Northern Ireland, noted for his originality and wit. He won the Hugo Award for Best Fan Writer in 1979 and 1980. His short story "Light of Other Days" was a Hugo Award nominee in 1967, as was his novel '' The Ragged Astronauts'' in 1987. Life Shaw was born and raised in Belfast, the eldest of three sons of a policeman. He learned of science fiction at about 11 years old when he read an A. E. van Vogt short story in an early edition of '' Astounding Science-Fiction'' magazine. During the Second World War American troops passed through Northern Ireland and often left their used SF magazines behind at Smithfield Market, where they were available for locals. He later described the experience as being more significant and long-lasting than taking LSD. He attended Belfast College of Technology. In 1950 he joined the group Irish Fandom, which also included another Northern Irish science fic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Theory Of Relativity
The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to the forces of nature. It applies to the cosmological and astrophysical realm, including astronomy. The theory transformed theoretical physics and astronomy during the 20th century, superseding a 200-year-old Classical mechanics, theory of mechanics created primarily by Isaac Newton. It introduced concepts including 4-dimensional spacetime as a unified entity of space and time in physics, time, relativity of simultaneity, kinematics, kinematic and gravity, gravitational time dilation, and length contraction. In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in ...

MacGuffin
In fiction, a MacGuffin (sometimes McGuffin) is an object, device, or event that is necessary to the plot and the motivation of the characters, but insignificant, unimportant, or irrelevant in itself. The term was originated by Angus MacPhail for film, adopted by Alfred Hitchcock, and later extended to a similar device in other fiction. The MacGuffin technique is common in films, especially thrillers. Usually, the MacGuffin is revealed in the first act, and thereafter declines in importance. It can reappear at the climax of the story but may actually be forgotten by the end of the story. Multiple MacGuffins are sometimes derisively identified as plot coupons. History and use The use of a MacGuffin as a plot device predates the name MacGuffin. The Holy Grail of Arthurian legend has been cited as an early example of a MacGuffin. The Holy Grail is the desired object that is essential to initiate and advance the plot. The final disposition of the Grail is never revealed, suggesting ...

Causality (physics)
Causality is the relationship between causes and effects. While causality is also a topic studied from the perspectives of philosophy and physics, it is operationalized so that causes of an event must be in the past light cone of the event and ultimately reducible to fundamental interactions. Similarly, a cause cannot have an effect outside its future light cone. As a physical concept In classical physics, an effect cannot occur ''before'' its cause which is why solutions such as the advanced time solutions of the Liénard–Wiechert potential are discarded as physically meaningless. In both Einstein's theory of special and general relativity, causality means that an effect cannot occur from a cause that is not in the back (past) light cone of that event. Similarly, a cause cannot have an effect outside its front (future) light cone. These restrictions are consistent with the constraint that mass and energy that act as causal influences cannot travel faster than the speed of li ...
