Z-Drive

Z-drive was the Grenick solution to inter-galactic travel. It is similar in concept to the Grenick Rift drive, but with several key differences.

It operates by moving the traveller to another coordinate plane that does not have a relation to the current Plane and then from there moves them back to the current coordinate plane, at any location.

This works because all points on P1 (X,Y,Z) are equidistant to P2 (A,B,C).

The process itself involves stretching P1 space into P2 and then from P2 to P1, the stretching itself uses a specialized particle that allows the manipulation of space in general.

While the Energy requirements are massive, this form of travel remains practical because of the vast distances between galaxy.

A form of Inter-Universal travel is theorized to be possible by simply stopping while still in P2. the Complications implicated by this primarily concern figuring out which coordinate plane the universe exists in.
