The first page of The Time Machine published by Heinemann. Time travel is the hypothetical activity of traveling into the past or future. Time travel is a widely recognized concept in philosophy and fiction, particularly science fiction. In fiction, time travel is typically achieved through the use of a hypothetical device known as a time machine.
Quantum mechanics of time travel. The theoretical study of time travel generally follows the laws of general relativity. Quantum mechanics requires physicists to solve equations describing how probabilities behave along closed timelike curves (CTCs), theoretical loops in spacetime that might make it possible to travel through time. [1][2][3][4 ...
Einstein’s equations do show that time travel is possible. This would not be developed for a time scale of centuries or even millennia from now. This would make it a Class II impossibility. The two major physical hurdles are energy and stability. Traveling through time would require the entire energy of a star or black hole.
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.

Titor's purported military insignia. John Titor and TimeTravel_0 are pseudonyms used on internet forums between 2000 and 2001 by an individual claiming to be an American military time traveler from the year 2036. [1][2] His posts discussed various aspects of time travel, and described future calamitous events, including a global nuclear war.
Mistaken for a lady's maid, Kendra is forced to quickly adapt to the period as she figures out how to get back to her own timeline. There are five books in the Kendra Donovan series, so if you ...
A temporal paradox, time paradox, or time travel paradox, is a paradox, an apparent contradiction, or logical contradiction associated with the idea of time travel or other foreknowledge of the future. While the notion of time travel to the future complies with the current understanding of physics via relativistic time dilation, temporal ...
Closed timelike curve. In mathematical physics, a closed timelike curve (CTC) is a world line in a Lorentzian manifold, of a material particle in spacetime, that is "closed", returning to its starting point. This possibility was first discovered by Willem Jacob van Stockum in 1937 [ 1 ] and later confirmed by Kurt Gödel in 1949, [ 2 ] who ...
