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 ...
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 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.

The Grandfather paradox, as depicted in Back to the Future, is a veritable brick wall of theoretical physics nuh-uhs. The range of mathematical processes we discovered show that time travel with ...
A recent study claims to have calculated a potential method of time travel. It involves a highly theoretical object called a “ring wormhole,” which is a type of wormhole that connects two ...
Theoretically, scientists say time travel is possible. The challenging part is recreating time travel in real life.
Killing baby Hitler is a thought experiment in ethics and theoretical physics which poses the question of using time travel to assassinate an infant Adolf Hitler. It presents an ethical dilemma in both the action and its consequences, as well as a temporal paradox in the logical consistency of time.
A time travel project probe from the year 2073 is sent to the year 1973 and goes wrong, creating a plague-ravaged, alternate timeline whose inhabitants are locked in a constant battle with killer robots. The hero must find a similar time machine in this alternate world and prevent the disaster from ever happening. 1994 Star Trek Generations
