time machines
Fictional chronal transports
Time machines are hypothetical devices for traveling through time—forward to the future or backward to the past.
The concept is a staple of science fiction: The time machine transported her to Victorian England.
While physics permits certain theoretical frameworks for time travel, no actual time machine exists.
The term sometimes describes anything that evokes the past: Old photographs are time machines.
