The speed of light has often been called the universal speed limit, but scientists believe that breaking it may be possible. Physicist Miguel Alcubierre proposed a real-life warp drive in 1994, but the drive’s power requirements were so enormous that it was relegated to merely theory. Space.com is reporting that scientists at the 100 Year Starship Symposium have made adjustments to Alcubierre’s calculations, which lowered the power requirements significantly.
“Everything within space is restricted by the speed of light,” explained Richard Obousy, president of Icarus Interstellar, a non-profit group of scientists and engineers devoted to pursuing interstellar spaceflight. “But the really cool thing is space-time, the fabric of space, is not limited by the speed of light.”
With this concept, the spacecraft would be able to achieve an effective speed of about 10 times the speed of light, all without breaking the cosmic speed limit.
The only problem is, previous studies estimated the warp drive would require a minimum amount of energy about equal to the mass-energy of the planet Jupiter.
