Warp drive may be more feasible than we thought

According to some physicists, the trick to achieving faster-than-light speed is relatively simple. All one has to do is figure out how to manipulate space-time itself -- because, after all, space-time isn't limited by the speed of light. Duh.

Scientist Harold "Sonny" White of NASA's Johnson Space Center explains:

The secret to warp speed is in spaceship design. Below is one concept:

I'm not sure how this works, but apparently the football is crucial.

There is, however, one major obstacle: energy. Studies have estimated that the minimum amount of energy required for a working warp drive would have to be "about equal to the mass-energy of the planet Jupiter."

Come on, scientists. "Feasible"? You keep using that word. I do not think it means what you think it means.
