Teleportation is the theoretical transfer of matter or energy from one point to another without traversing the physical space between them. [1] It is a common subject in science fiction and fantasy literature, film, video games, and television. In some situations, teleporting is presented as time traveling across space.
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.

They can return from the same location when someone in the future re-opens the Net for them at an agreed-upon "rendezvous" time.
This is an example of mental time travel in animals. It was not a result of associative learning, that they actually chose the utensil instead of the food reward, since the scientists ran another experiment to account for that. Other examples, such as food caching by birds, may be examples of mental time travel in non-humans.
