The idea of warping space as a means of propulsion has enjoyed theoretical study by physicists such as Miguel Alcubierre, who has speculatively designed his own drive. However, no actual practical technological approach has been proposed. Currently there is no known way to either naturally or artificially create a finite and bounded space-time region or "bubble". Such a region is necessary to localy suspend or encapsulate the spacecraft within its view of a “normal” space-time. Concurrently, external from that region, there would exist a “warped” space-time, in which the region moves through space-time at velocities exceeding the speed of light. Based on Alcubierre’s warp drive, a futuristic engine that uses dark energy to propel a spaceship faster than light, has been proposed, and could revolutionize space travel according to an article on the web site of Cosmos Magazine [1]. The idea is backed up by calculations made by physicists at Baylor University in Waco, Texas. Like something from Star Trek, their theory says that a spacecraft could travel at warp speed in a bubble of space-time, by manipulating dark energy, the mysterious invisible force accelerating the expansion of the universe. The spacecraft would essentially remain in the same place, while space-time ahead of the spaceship would shrink, expanding again behind it. Even if it was possible, though, a dark energy warp drive wouldn’t be very practical - the experts estimate it would consume the entire mass of Jupiter to move a spaceship just 10 meters at faster-than-light speed.
