The Time Displacement Engine or TDE makes use of a temporal core and field emitters to travel through time. The technology can be used on either a person or a space craft depending on how much power is used and how big the field emitters are.
Operation
The technology works by producing a spherical energy field that warps space-time in such a way to push the contents of the field from one point in spacetime to another. At the local focal point, the field of temporal energy becomes saturated and is carefully controlled to direct the field toward a remote focal point. At this remote focal point, the field expands out from the center before finally the two regions of space occupy at the same place at the same time for a nano-second. Existing matter at the remote location is pushed out of the way as the field expands leaving a void at the center prior to displacement.
Dangers
This process of time travel by sheer force is dangerous, and without proper shielding the distortions and energy released is capable of ripping a ship (or a person) apart. If the TDE is used on a person it becomes extraordinarily painful, occasionally the sheer force can be like standing in the center of a tornado unless the TDE is calibrated and modulated exactly to bring the target and source points together in perfect unity.
Scaling
While this technology scales in the extreme because of the dangerous nature of the process, the largest known TDE is on the dorsal central core of Starbase Tranquility orbiting Markab Prime.
