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 ...
Temporal paradox. 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 ...
The study of time travel generally follows the laws of general relativity. Quantum mechanics, on the other hand, needs physicists to solve equations describing how probabilities (represented by density matrices) behave along closed timelike curves (CTCs). CTCs are loops in spacetime that might make it possible to travel through time.
The Novikov self-consistency principle, also known as the Novikov self-consistency conjecture and Larry Niven 's law of conservation of history, is a principle developed by Russian physicist Igor Dmitriyevich Novikov in the mid-1980s. Novikov intended it to solve the problem of paradoxes in time travel, which is theoretically permitted in ...
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.
Casey McQuiston's second novel (following Red, White, and Royal blue, which is going to be a major motion picture this summer) is a queer time-loop romance set on the Q train in New York City, and ...
Chronology protection conjecture. The chronology protection conjecture is a hypothesis first proposed by Stephen Hawking that laws of physics beyond those of standard general relativity prevent time travel on all but microscopic scales - even when the latter theory states that it should be possible (such as in scenarios where faster than light ...
Time loop. The time loop or temporal loop is a plot device in fiction whereby characters re-experience a span of time which is repeated, sometimes more than once, with some hope of breaking out of the cycle of repetition. [1] Time loops are constantly resetting; when a certain condition is met, such as a death of a character or a certain point ...
