Well, so how *does* warp work?”
A powerful, asymmetric subspace field is established around the ship by the warp nacelles. The field is composed of nested layers, each pushing against the one beyond it. This drives the ship forward, at a super-luminal velocity. The nacelles are powered by a tuned plasma stream from the warp core Matter/Antimatter Reactor (M/AMR). Injectors feed the plasma into warp field coil segments at specific times, causing pulses to run the length of the nacelle, front to back. This peristaltic flow causes the push of the nested warp fields, and moves the ship forward. The warp field wraps around the ship in a two-lobed bubble, with the locus at Main Engineering (by design). The shape of the ship determines the efficiency of the field, and this explains why the Enterprise has such a sleek design. Meanwhile, the subspace field reduces the inertial mass of the ship, aiding in maneuvering. In fact, a small subspace field is kept around the ship at Impulse speeds, so the Impulse drives have less mas
