Folded-space transporter
A folded-space transporter is a device that moves objects via a dimensional shift. In the Federation, the principles of folded-space transport was first proposed in the Elway Theorem (External Link), though it was discarded in the mid-22nd century due to its dangerous effects on humanoid tissue.
The Ansata (External Link) separatist movement of Rutia IV (External Link) uses a folded-space transporter called an inverter, based on the Elway Theorem. Ansata leader Kyril Finn (External Link) credited the inverter with reinvigorating his group despite the fatal results of its use, because it allowed his forces to move quickly and with complete surprise anywhere they wished, including areas protected by force fields, and to escape without fear of being tracked.
The Sikarians of the Delta Quadrant employ a type of folded-space transporter called a spatial trajector, which had a range of some 40,000 light years. The crew of the USS Voyager attempted unsuccessfully to negotiate for this technology in 2371. When some members of the crew obtained a trajector module through other means, they learned that the trajector was fundamentally incompatible with Federation technology.
