The concept you are referring to is known as "time travel with spatial displacement" or "chronotopology." It combines the idea of time travel with the concept of spatial displacement, allowing for movement through time while simultaneously moving backward or forward in space.
In traditional time travel scenarios, an individual would travel to a specific point in time while remaining in the same physical location. However, in chronotopology, the time traveler experiences a displacement in space as they move through time.
The exact mechanisms and theoretical framework for chronotopology may vary depending on the specific fictional or speculative model being considered. In some science fiction stories, this form of time travel is portrayed as a result of bending or warping spacetime through advanced technologies or the manipulation of hypothetical constructs like wormholes.
Essentially, chronotopology envisions a scenario where a person can travel to a different time period while also being transported to a different location in space. This allows for the exploration of distant places and eras through time travel, effectively combining temporal and spatial displacement into a single concept.
