Shocking or intriguing NASA challenges physics to build faster than light spaceship warp drive

NASA scientist Harold White has stunned the world with his announcement that he and his team has begun work on the development of a faster-than-light Warp Drive spaceship that can move faster than the speed of light defying Albert Einstein’s Theory of Special Relativity. Warp Drive, which is all set to challenge the light speed barrier, could result in speeds that could take a spacecraft to Alpha Centauri in a only two weeks even though the system is 4.3 light-years away! The idea sounds fascinating but disobeys the laws of physics.
In his 1994 paper titled The Warp Drive: Hyper-Fast Travel Within General Relativity physicist Miguel Alcubierre had suggested a mechanism by which space-time could be “warped” both in front of and behind a spacecraft. The idea immediately caught White’s attention.
“Remember, nothing locally exceeds the speed of light, but space can expand and contract at any speed. However, space-time is really stiff, so to create the expansion and contraction effect in a useful manner in order for us to reach interstellar destinations in reasonable time periods would require a lot of energy,” White told io9.
The Theory of Special Relativity does not allow objects to move faster than the speed of light within space-time. To increase the speed of moving objects to match the speed of light, it would need infinite amount of energy. White in a way suggested horrific amounts of energy —equal to the mass-energy of planet Jupiter (which is 1.9 × 1027 kilograms or 317 Earth masses). As a result, the idea was brushed aside as being far too impractical.
White later collaborated with Mark Rademaker, an artist, to create a new, more realistic design of what such a ship might actually look like. The updated model is more compact and chunkier and includes a sleek ship nestled at the center of two massive rings of negative energy which will create the warp bubble.
At the 100 Year Starship Conference in Atlanta, he said that the Warp Drive could be powered by a mass that’s even less than that of the Voyager 1 spacecraft. The reduction in mass from a Jupiter-sized planet to an object that weighs a mere 1,600 pounds completely reset White’s sense of plausibility — and NASA’s.
Warp Drive for FTL travel is at the level of speculation since NASA also considers that FTL travel is impossible. FTL results in time travel and time travel is considered far more impossible than light travel. Dr White too admits his research is still small-scale and is light years away from any type of engine that could be constructed into a spaceship like the USS Enterprise.
The story so far. Here are a number of clips from the BBC Explorations series that looks at what we have achieved so far in space travel.
