Warp 5... Sir! :}

How warp drive is supposed to work: here.

And some more technical/practical problems: here.

''Known for the Mexican physicist Michael Alcubierre who originally developed the idea in the 1990's, an Alcubierre warp drive would create a bubble of energy behind the ship and a lack of energy in front of the ship, like a giant cosmic wave a space ship could surf. That particular section of space can travel faster than the speed of light in the surrounding space, and anything on or in that bubble will accelerate with it.''
