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 ...
The key to the whole idea is wormholes—specifically, a type of wormhole called a ring wormhole. Now, wormholes are already entirely theoretical, so this discussion is going to get weird.
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 ...
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 ...

The novel features travel via wormholes between alternate universes. [57] [58] [59] Diaspora: Greg Egan: 1997: The novel features scientifically well founded depictions of wormholes. [60] [61] Timeline: Michael Crichton: 1999: In the novel traversable wormholes are used for time travel along with the theory of quantum foam. [62] [63] The Light ...
Traversable wormholes may be more than science fiction. Three new studies propose new theories for how to construct one. Human-Safe Wormholes Could Exist in the Real World, Studies Find
Outer Wilds (2019): A video game involving time travel which does not follow the principle, causing a game over if the player experiments to test it. All time travel in the Hallmark Channel original series The Way Home follows the Novikov self-consistency principle. Two of the main characters can travel backwards in time by jumping into a pond ...
