Warp drive is a technology that allows space travel at faster-than-light speeds. It works by generating warp fields to form a subspace bubble that envelops the starship, distorting the local spacetime continuum and moving the starship at velocities that could greatly exceed the speed of light. These velocities are referred to as warp factors. Warp drive is the most common form of interstellar propulsion used in the Milky Way Galaxy, making interstellar exploration, commerce, and warfare possible.
