  2. Time travel - Wikipedia

    en.wikipedia.org/wiki/Time_travel

    Time travel is a concept in philosophy and fiction, particularly science fiction. In fiction, time travel is typically achieved through the use of a device known as a time machine. The idea of a time machine was popularized by H. G. Wells's 1895 novel The Time Machine. [1] It is uncertain whether time travel to the past would be physically ...

  3. Time dilation - Wikipedia

    en.wikipedia.org/wiki/Time_dilation

    The faster the relative velocity, the greater the time dilation between them, with time slowing to a stop as one clock approaches the speed of light (299,792,458 m/s). In theory, time dilation would make it possible for passengers in a fast-moving vehicle to advance into the future in a short period of their own time.

  4. Speed - Wikipedia

    en.wikipedia.org/wiki/Speed

    If the average speed and the time of travel are known, the distance travelled can be calculated by rearranging the definition to = ¯. Using this equation for an average speed of 80 kilometres per hour on a 4-hour trip, the distance covered is found to be 320 kilometres.

  5. Time travel in fiction - Wikipedia

    en.wikipedia.org/wiki/Time_travel_in_fiction

    A time slip is a plot device in fantasy and science fiction in which a person, or group of people, seem to travel through time by unknown means. [12] [13] The idea of a time slip has been used in 19th century fantasy, an early example being Washington Irving's 1819 Rip Van Winkle, where the mechanism of time travel is an extraordinarily long sleep. [14]

    As far as timing goes, travel seems to be easier at certain times of year, seemingly at times related to the changing seasons. Claire first traveled back in time just after the festival of Beltane ...

  7. Faster-than-light - Wikipedia

    en.wikipedia.org/wiki/Faster-than-light

    Faster-than-light (superluminal or supercausal) travel and communication are the conjectural propagation of matter or information faster than the speed of light (c). The special theory of relativity implies that only particles with zero rest mass (i.e., photons) may travel at the speed of light, and that nothing may travel faster.

  8. Warp drive - Wikipedia

    en.wikipedia.org/wiki/Warp_drive

    Some argue that these effects mean that although it's not possible to travel faster than the speed of light, both space and time "warp" to allow travelling the distance of one light year, in less than a year. Although it is not possible to travel faster than the speed of light, the effective speed is faster than light.
