Interstitial space

In physics, interstitial space or fractal space is a higher-dimensional space that spacecraft can travel at superluminal speeds.

Interstitial space is a multi-dimensional fractal representation of the physical universe, in which is contained an infinitely repeating pattern of the universe. Theoretically, this means that a spacecraft could travel any distance inside interstitial space and still return to its point of origin. This same principle also means a spacecraft could travel to any other point within the universe almost instantly, given that it could calculate such a short route.
