A warp drive to achieve faster-than-light travel — a concept popularized in television's Star Trek — may not be as unrealistic as once thought, scientists say. A warp drive would manipulate space-time itself to move a starship, taking advantage of a loophole in the laws of physics that prevent anything from moving faster than light. A concept for a real-life warp drive was suggested in 1994 by Mexican physicist Miguel Alcubierre, however subsequent calculations found that such a device would require prohibitive amounts of energy. Now physicists say that adjustments can be made to the proposed warp drive that would...

What: A spacecraft that travels at faster-than-light speeds by distorting, or “warping,” the fabric of spacetime. Instead of trying to move through space, the warp drive moves space itself. The ship sits inside a bubble of spacetime bound by a negative energy field that races across the cosmos. Why: Chemical and nuclear propulsion, solar sails and ion thrusters all are too slow to reach the nearest star systems within a human life span. At faster-than-light speed (more than 186,000 miles per second), a warp-drive ship would travel 4.5 light-years to Alpha Centauri, the closest sun to our own, in about...

Light Speed a Barrier? To go, the children of tomorrow may have had to discover what is believed impossible today -- how to travel faster than light. Mel Zisfein, deputy director of the national Air and Space Museum, and an aerosynamicist amoung other things, has noted a similarity between the way most people today regard "C," the speed of light, and the way many people a generation or so ago regarded "a", the speed of sound. For this publication, he sketched the illustrations which appear on the following page, and drafted the following... "Some people used to look at...

NASA Researchers Put New Spin On Einstein's Relativity Theory Albert Einstein might be astonished to learn that NASA physicists have applied his relativity theory to a concept he introduced but later disliked namely that two particles that interact could maintain a connection even if separated by a vast distance. Researchers often refer to this connection as "entanglement." Researchers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., have discovered that this entanglement is relative, depending on how fast an observer moves with respect to the particles, and that entanglement can be created or destroyed just by relative motion. This might change...

Will Spacecraft ever Go Faster than the speed of Light? Compiled by VANNROX for BlueBay Source list and references included.Primary Sources include MSNBC,NASA,Analog, and other online publications. February 16 2003 Marc Millis, who manages NASA?s Breakthrough Propulsion Physics Program, says he?s more interested in ways ?to propel spacecraft farther, faster, more efficiently? than in the grand cosmological questions. ?And my ears perk up more when I hear about new experimental evidence than theories,? he says. There are a number of such theories based on experimental evidence. His top three of interest are: Photon Tunneling.Some experiments have indicated that photons...

HOUSTON — Beyond the security gate at the Johnson Space Center’s 1960s-era campus here, inside a two-story glass and concrete building with winding corridors, there is a floating laboratory. Harold G. White, a physicist and advanced propulsion engineer at NASA, beckoned toward a table full of equipment there on a recent afternoon: a laser, a camera, some small mirrors, a ring made of ceramic capacitors and a few other objects. He and other NASA engineers have been designing and redesigning these instruments, with the goal of using them to slightly warp the trajectory of a photon, changing the distance it...

A few months ago, physicist Harold White stunned the aeronautics world when he announced that he and his team at NASA had begun work on the development of a faster-than-light warp drive. His proposed design, an ingenious re-imagining of an Alcubierre Drive, may eventually result in an engine that can transport a spacecraft to the nearest star in a matter of weeks — and all without violating Einstein's law of relativity. We contacted White at NASA and asked him to explain how this real life warp drive could actually work.
