The “Real” Warp Drive

UnknownSure, it sounds like science fiction. But some researchers suggest that warp drives might actually be a possibility:

’…nothing in relativity suggests that spacetime cannot contract or stretch faster than light. If spacetime around the ship bends in a certain way, the craft can be swiftly propelled and, in theory, travel a vast distance in little time.

The ship itself does not violate the Einsteinian prohibition on faster-than-light travel because, within its bubble of spacetime, the ship is not traveling faster than light. To a stationary observer, the ship would appear to be moving at light speed (or close to it). But it is actually the surrounding distortion of spacetime that is driving the bubble from origin to destination, kind of like a surfer riding a wave. Consequently, the ship is not empirically moving faster than light relative to anything else in its bubble. Yet if the ship and light leave the same space at the same time, the ship might get there faster than the light does.…’
