Time Machine

A time machine is a fictional machine for the implementation of time travel. Such machines that will allow any back and forth movement in time, are fictions: Although taking advantage of time dilation time travel into the future according to present knowledge feasible, but the design of a machine that accomplishes a journey into the past is, after current knowledge, not possible.

Time machines are a popular subject of science fiction. Seriously itself, science has, inter alia, on the basis of Albert Einstein's assumptions of a modifiable space-time and of findings at reduced spontaneous formation of matter in addition to large masses only with the transmission of 'information' in the past. However, these experiments do not appear due to the conditions ( high energy demand, large dimension) in the future be realized.

Time machines are often also the starting point for an alternative world stories. The fact that a time traveler changes the past, the story evolved differently narrated, and a parallel history in the making.

Examples

Fictional literature

• The first novel, which treated the subject was The Time Machine by HG Wells.

• In the book, 1227 Lost in the Middle Ages by Pete Smith revolve in opposite laser beams in a Bose -Einstein condensate. The Time Traveler's sitting comfortably on a sofa. This time machine is based on the research of Ronald Mallett and Lene Hau. The opposite circular laser beams produce a curvature of spacetime.

• In the book series Justin Time by Peter Schwindt you stand in the " time portal " in a gravitational field, which forms the top of a wormhole. This wormhole is opened by a trapped in a glass ball black hole. It is repeatedly emphasized that the realization of time machines only after the development of the general field theory was possible. From the fourth band betrayal in Florence there are portable time machine, called Wells aggregates. These can be taken on the journey, which facilitates the return significantly. Moreover, these time machines can be used as a teleporter.

• In Roman letters of the Chinese past by Herbert Rosendorfer a mandarin from the 10th century used a in the former Imperial China designed time machine to put a thousand years into the future. But this time machine transports only a people; the bag must not be too hard, otherwise the time traveler is probably stuck on the road. The time travel is abrupt and without loss of time. Because of the Earth's rotation, however, the place of departure and the destination are different. The time traveler can be produced by " time travel document ", which is deposited at a contact point ( and how vanishes by magic ), agree with his " Time Home " - where the energy for time travel is derived is not stated exactly in the novel.

• In the novel Timeline by Michael Crichton one uses quantum mechanics to travel through time. However, physical and psychological damage can be caused by the trip if the programming is not error-free.

• The novel The End of Eternity by Isaac Asimov describes a culture based entirely on time travel. This ensures the titular organization of eternity away by constantly bringing about time paradoxes for stability in human history about 70,000 centuries and coordinates inter-temporal trade. ( Pseudo-) scientific basics to explain the phenomenon of time travel, are not specified, indicated empirical characteristics of time travel itself only. The focus of the action is on the societal impact and ultimately the individual fates of the actors.

• Time Machine Stories (it. Macchina del tempo ) is an Italian comic book series.

Literature

In the non-fiction book A Briefer History of Time by Stephen Hawking and Leonard Mlodinow the subject of time machine or time travel and wormholes in Chapter ten is discussed. The laws of physics thus seem indeed allow time travel, but these are illogical: Why have the problems of humanity in the present, if in the future time travel would be possible someday? Where are the visitors from the future?

Science and remuneration

In Physics of the Impossible Michio Kaku shows the latest scientific knowledge in realistic ways to realize a time machine handy. Accordingly, the construction of a time machine due to the technological and financial effort will only be possible in the distant future.

Fictional films

• HG Wells novel was made ​​into a film in 1960, titled The Time Machine. A remake was created in 2002 under the title The Time Machine.

• In the British series Doctor Who (1963 ) the protagonist travels in a time machine called the Tardis, which has the appearance of a police cell, through time.

• In the movie trilogy Back to the Future of Fluxkompensator plays ( flux capacitor, literally actually " flow condenser ", not " compensator " ) play a significant role. It is housed in a vehicle of the brand De Lorean, DMC 12 The required capacity of 1.21 gigawatts for a journey through time provides a nuclear fission, for which the time machine requires plutonium. After a renovation in 2015, the energy is supplied by a generator powered by waste merger.

• Time travel is a central theme in the films of the Terminator series. Here is a fighting machine is sent from the future to the past in order to eliminate an important person in history or - to protect - the second and third part of the series.

• Was established in 2006, the Dutch youth film Crusade in jeans based on the novel by Thea Beckman. Here goes a youth soccer players in the past in order to change a football result but lands in the Middle Ages the middle of a children's crusade.
