Black Holes In Fiction
Black holes, objects whose gravity is so strong that nothing including light can escape them, have been depicted in fiction since before the term was coined by John Archibald Wheeler in the late 1960s. The earliest stories featuring what would later be called black holes, such as E. E. Smith's 1928 story ''The Skylark of Space'' and its "black sun", typically portrayed them as hazards to spacefarers. Later works such as the 1975 '' Space: 1999'' episode "Black Sun" have occasionally done likewise, and a few have even depicted black holes being outright weaponized, one example being the 1982 novel '' The Space Eater'' by David Langford. A concept portrayed in many early works featuring black holes is that of gravitational time dilation—whereby time passes more slowly closer to a black hole as a consequence of general relativity—seen in works like Poul Anderson's 1968 short story "Kyrie" as well as Frederik Pohl's 1977 novel '' Gateway'' and the rest of his Heechee Saga; the op ...

Black Hole
A black hole is a region of spacetime where gravitation, gravity is so strong that nothing, including light or other Electromagnetic radiation, electromagnetic waves, has enough energy to escape it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary (topology), boundary of no escape is called the event horizon. Although it has a great effect on the fate and circumstances of an object crossing it, it has no locally detectable features according to general relativity. In many ways, a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with thermal radiation, the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly. Obje ...

Tomorrow Is Yesterday
"Tomorrow Is Yesterday" is the nineteenth episode of the first season of the American science fiction television series ''Star Trek''. Written by D. C. Fontana and directed by Michael O'Herlihy, it first aired on January 26, 1967. It was the first Star Trek episode to be written solely by a woman (Dorothy Fontana had previously written the teleplay for the episode “Charlie X” but the story was credited to Gene Roddenberry). In the episode, the ''Enterprise'' is thrown back to Earth in the 1960s where the US Air Force detects it so the crew must find a way to correct the damage to the timeline. Plot The USS ''Enterprise'' is thrown back in time to Earth during the 1960s by the effects of a high-gravity " black star". ''Enterprise'' ends up in Earth's upper atmosphere, and is picked up as a UFO on military radar. A U.S. Air Force F-104 interceptor piloted by Captain John Christopher (Roger Perry), is scrambled to identify the craft. Fearing an attack, Captain Kirk orders ...

Proteus Unbound
In Greek mythology, Proteus (; Ancient Greek: Πρωτεύς, ''Prōteus'') is an early prophetic sea-god or god of rivers and oceanic bodies of water, one of several deities whom Homer calls the " Old Man of the Sea" ''(hálios gérôn)''. Some who ascribe a specific domain to Proteus call him the god of "elusive sea change", which suggests the constantly changing nature of the sea or the liquid quality of water. He can foretell the future, but, in a mytheme familiar to several cultures, will change his shape to avoid doing so; he answers only to those who are capable of capturing him. From this feature of Proteus comes the adjective protean, meaning "versatile", "mutable", or "capable of assuming many forms". "Protean" has positive connotations of flexibility, versatility and adaptability. Name origin Proteus' name suggests the "first" (from Greek "πρῶτος" ''prōtos'', "first"), as ''prōtogonos'' (πρωτόγονος) is the "primordial" or the "firstborn". It is ...

Charles Sheffield
Charles Sheffield (25 June 1935 – 2 November 2002), an English-born mathematician, physicist and science-fiction writer, served as a President of the Science Fiction and Fantasy Writers of America and of the American Astronautical Society. His novel ''The Web Between the Worlds'', featuring the construction of a space elevator, was published almost simultaneously with Arthur C. Clarke's novel on the subject, ''The Fountains of Paradise'' - a coincidence that amused them both. Excerpts from both Sheffield's ''The Web Between the Worlds'' and Clarke's ''The Fountains of Paradise'' have appeared recently in a space-elevator anthology, '' Towering Yarns''. Sheffield served as Chief Scientist of Earth Satellite Corporation, a company that processed remote-sensing satellite data. The association gave rise to many technical papers and two popular non-fiction books, ''Earthwatch'' (1981) and ''Man on Earth'' (1983), both collections of false-colour and enhanced images of Eart ...

Artificial Gravity
Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of reference), as opposed to the force experienced in linear acceleration, which by the equivalence principle is indistinguishable from gravity. In a more general sense, "artificial gravity" may also refer to the effect of linear acceleration, e.g. by means of a rocket engine. Rotational simulated gravity has been used in simulations to help astronauts train for extreme conditions. Rotational simulated gravity has been proposed as a solution in human spaceflight to the adverse health effects caused by prolonged weightlessness. However, there are no current practical outer space applications of artificial gravity for humans due to concerns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur C
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a ...

Imperial Earth
''Imperial Earth'' is a science fiction novel by British writer Arthur C. Clarke, published in 1975 by Gollancz Books. The plot follows the protagonist, Duncan Makenzie, on a trip to Earth from his home on Titan, in large part as a diplomatic visit to the U.S. for its quincentennial in 2276, but also to have a clone of himself produced. The book was published in time for the U.S. bicentennial in 1976. Plot summary Duncan Makenzie is the latest generation of the 'first family' of Titan, a colonised moon of Saturn. Originally settled by his grandfather Malcolm Makenzie in the early 23rd century, Titan's economy has flourished based on the harvest and sale of hydrogen mined from the atmosphere, which is used to fuel the fusion engines of interplanetary spacecraft. As the plot opens in 2276, a number of factors are combining to make a diplomatic visit to the 'mother world' of Earth a necessity. Firstly, the forthcoming 500th anniversary of US Independence, which is bringin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
