Warp drive is a form a faster-than-light travel. Human ships used warp drive by the 26th century and even into the 51st century. The ships of the 26th century were powered by antimatter, which may be required for warp drive. Should the navigational computers be tampered with while a ship is in warp drives, it could disintergrate. (DW: Earthshock, DW: The Girl in the Fireplace)
