The warp drive: hyper-fast travel within general relativity
read the original abstract
It is shown how, within the framework of general relativity and without the introduction of wormholes, it is possible to modify a spacetime in a way that allows a spaceship to travel with an arbitrarily large speed. By a purely local expansion of spacetime behind the spaceship and an opposite contraction in front of it, motion faster than the speed of light as seen by observers outside the disturbed region is possible. The resulting distortion is reminiscent of the ``warp drive'' of science fiction. However, just as it happens with wormholes, exotic matter will be needed in order to generate a distortion of spacetime like the one discussed here.

Steering a warp drive without exotic matter
An accelerating positive-energy warp drive is constructed by matching a flat cavity to a Kinnersley photon rocket, obeying the derived control law −ṁ ≥ 3m|a| and needing no exotic matter.
