Spin-Two Drive

Spin-two is a reference to the particle of gravity, the graviton, although spin one-half particles (fermions) are more important to the drive's operation.

To develop the spin-two drive Dr. Franklin Benjamin used the wormhole drive's ability to cast exotic mass-energy into nonlocal links which for all intent and purposes act like narrow wormholes. 

Nonlocal describes particles that are too far apart to causally affect each other (see nonlocal links above). 

The cast energy causes fermionic particles, particles with one-half quantum spin, to flip their spin (say from up to down). The nonlocal partners to these fermions, entangled particles in other words, assume the opposite spin state. By modulating the mass-energy, a pulse can travel down the nonlocal link at a frequency determined by the spin-two drive.

Using the drive's ability to create pulsating “bubbles” of negative mass-energy a ship inserted into the nonlocal link is pulled and pushed along to the far end.

Once the ship enters the link the drive shuts down and the decaying pulses eventually allow the link to “relax” to its original state. By that time the ship has already emerged at the nonlocal destination. The link portals now decay completely and the nonlocal tunnel closes.

The advantages of the spin-two drive over the wormhole drive are many. Because the spin-two drive is only opening an already existing mini-wormhole link the exotic mass-energy needed is one-tenth that of a wormhole drive which must force the wormhole open from beginning to end in the wormhole dimension.

Another advantage is that the nonlocal links are by definition usually connecting regions of space that are far removed. Jumps of a thousand light-years are common compared to the forty light-year jumps possible with the wormhole drive. In fact, there is no limit to the jump distant but because the distribution of jump lengths follows a gaussian distribution very long links are harder to find in the quantum foam and therefore it takes a longer and longer time to make very long jumps . . .
