  2. Wormhole - Wikipedia

    en.wikipedia.org/wiki/Wormhole

    If two points are connected by a wormhole whose length is shorter than the distance between them outside the wormhole, the time taken to traverse it could be less than the time it would take a light beam to make the journey if it took a path through the space outside the wormhole. However, a light beam traveling through the same wormhole would ...

    A recent study claims to have calculated a potential method of time travel. It involves a highly theoretical object called a “ring wormhole,” which is a type of wormhole that connects two ...

  4. Time travel - Wikipedia

    en.wikipedia.org/wiki/Time_travel

    Time travel is the hypothetical activity of traveling into the past or future. 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 ...

  5. Wormholes in fiction - Wikipedia

    en.wikipedia.org/wiki/Wormholes_in_fiction

    In the FOX/Sci-Fi series Sliders, a method is found to create a wormhole that allows travel not between distant points but between different parallel universes; [119] [120] objects or people that travel through the wormhole begin and end in the same location geographically (e.g. if one leaves San Francisco, one will arrive in an alternate San ...

  6. Chronology protection conjecture - Wikipedia

    en.wikipedia.org/wiki/Chronology_protection...

    This occurs when the two wormhole mouths, call them A and B, have been moved in such a way that it becomes possible for a particle or wave moving at the speed of light to enter mouth B at some time T 2 and exit through mouth A at an earlier time T 1, then travel back towards mouth B through ordinary space, and arrive at mouth B at the same time ...

  7. Faster-than-light - Wikipedia

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

    As with the Alcubierre drive, travelers moving through the wormhole would not locally move faster than light travelling through the wormhole alongside them, but they would be able to reach their destination (and return to their starting location) faster than light traveling outside the wormhole.

  8. Intergalactic travel - Wikipedia

    en.wikipedia.org/wiki/Intergalactic_travel

    A wormhole is a hypothetical tunnel through space-time that would allow instantaneous intergalactic travel to the most distant galaxies even billions of light years away. Wormholes are allowed by general relativity .

    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 ...
