NASA Scientist Harold “Sonny” White is working on a warp drive at the Johnson Space Center in Houston, TX. His research is being funded by the Defense Advanced Research Projects Agency (DARPA). The warp drive would permit “fast than light” travel and permit space craft to visit neighboring star systems. The article explains that many scientists are skeptical that White’s proposed warp drive will work. White says that he is “on the verge” of completing a workable model of the warp drive. The warp drive works on the principle of compressing space time ahead of the space ship and expanding space time to the rear of the space ship. (See diagram above.) In theory the occupants of the space ship would be “unaffected” by the time compression and time dilation. The design concept relies on “negative energy.” No one has measured negative energy, but quantum mechanics predicts that it exists.
