The Alcubierre "Warp Drive"
A recent scientific paper in theroretical physics, suggesting a technique for making an object move faster than light by expanding and contracting the fabric of space. This is not SF, this is reality. (Of course, actually constructing a drive based upon these principles is far beyond our current technical know-how. Just like the Tipler Time Machine, which starts with "Take a cylinder of neutronium half a light year long, and spin it around it's axis with a velocity of half the speed of light...")
