Nanotechnology, the mysterious Casimir Force, and interstellar spaceships

Travel through wormholes, time machines and hovering landspeeders are the stuff of science fiction novels. Nevertheless, scientists have suggested that the quantum mechanics of something called the Casimir effect can be used to produce a locally mass-negative region of space-time, a phenomenon that theoretically could be used to stabilize a wormhole to allow faster than light travel.
