 However, several objections raised against the Alcubierre drive appear to rule out the possibility of actually using it in any practical fashion.Another possibility predicted by general relativity is the traversable wormhole, which could create a shortcut between arbitrarily distant points in space.As with the Alcubierre drive, travelers moving through the wormhole would not "locally" move faster than light travelling through the wormhole alongside them, but they would be able to reach their destination (and return to their starting location) faster than light traveling outside the wormhole.
