time travel
Quick Summary
Time travel, a prominent theme in science fiction, explores the concept of moving between different points in time. H.G. Wells's The Time Machine (1895) is a seminal work that popularized the idea of mechanical time travel.12
In physics, the concept of time is not absolute. Theories like special relativity suggest that time can be experienced differently depending on an observer's motion, a phenomenon known as time dilation. While theoretical constructs like wormholes could potentially offer shortcuts through spacetime, they are considered unstable and their existence is unproven.345
Science fiction often uses time travel to explore historical change, alternate histories, and the consequences of altering past events, as seen in works like A Connecticut Yankee in King Arthur's Court and 11/22/63.1
