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 ...
Time travel is deterministic and locally free, a paper says—resolving an age-old paradox.. This follows research observing that the present is not changed by a time-traveling qubit.. It’s ...
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), which are theoretical loops in spacetime that might make it possible to travel through time.

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.

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
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 ...
