A loophole where you don't move, space does the moving for you.
means A faster-than-light propulsion concept, mostly from science fiction (and a sliver of theoretical physics), in which a vessel rides a bubble of distorted spacetime instead of 'moving' through it in the usual sense.
from 'Warp' comes from an old weaving term — the lengthwise threads held taut on a loom, and by extension the act of bending or twisting something out of its true, flat shape. That sense of 'bending the fabric of' made it a natural fit when 20th-century sci-fi writers needed a word for distorting space itself; 'Star Trek' popularized 'warp drive' specifically, cementing it as the go-to term for fictional faster-than-light travel. The 'drive' half is just the ordinary engineering sense — a mechanism that propels — borrowed from drivetrains and engines generally.
- physics basis
- based on real math by Miguel Alcubierre, 1994
- the trick
- compresses space ahead, expands it behind you
- the catch
- needs exotic matter nobody has ever found
- speed limit
- technically never breaks light speed locally
