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 ...
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.

A bootstrap paradox, also known as an information loop, an information paradox, [6] an ontological paradox, [7] or a "predestination paradox" is a paradox of time travel that occurs when any event, such as an action, information, an object, or a person, ultimately causes itself, as a consequence of either retrocausality or time travel.

Ronald Mallett loves the concept of time travel. He has since he was a kid. At 77, the former University of Connecticut physics professor still isn’t backing down from his theory: A spinning ...
The time-travel device, a portal called "the Net", remains in the time-traveler's present, while sending the time-traveler to a particular location (called "the drop") and time. They can return from the same location when someone in the future re-opens the Net for them at an agreed-upon "rendezvous" time.
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.
The presence of closed timelike lines indicates the possibility of time travel into the past. This creates the foundation for a time machine based on a circulating cylinder of light. Mallett's book, Time Traveler: A Scientist's Personal Mission to Make Time Travel a Reality, co-written with author Bruce Henderson, was published
