Spacial displacement was an ability built into the improved DeLorean time machine, which allowed for the time traveler to travel through space instantaneously as would make the jump through time. Destinations were locked to Earth's plane and numerous cities and regions could be visited outside of Hill Valley. It is assumed that when a destination was requested, its coordinates were located and mapped out. It is still unclear if this ability made the car a true teleportation machine.
Some cities and regions visited by the time machine:
- Chattanooga, Tennessee
- Salem, Massachusetts
- Chicago, Illinois
- Rome, Italy
- Caribbean Islands
- England
- Egypt
Behind the scenes
Because of the movement of the Earth (rotation, revolution about the Sun, and movement of the solar system and galaxy), the DeLorean Time Machine would already have needed to accomplish spacial displacement even before the first temporal displacement experiment. Doc Brown's calculations would have needed to take into account numerous variables even for Einstein to leave the parking lot of the Twin Pines Mall at 1:01 am and to appear on the same parking lot at 1:02 am.
If there were no spacial displacement, temporal displacement would place the time machine at the same point in the universe that it had been in previously, rather than at the same location on Earth; and the Earth itself would not be at that same point in space. Given the complexity of the mathematical equations simply for keeping the DeLorean in one relative location, such as Hill Valley, it is understandable that Doc had to work for additional years on spacial displacement calculations in order to move the DeLorean from one point on Earth to another.
