Warp rive is a form of faster-than-light propulsion in the fictional universe of Star Trek, capable of propelling spacecraft or objects to many multiples of the speed of light but avoiding the problems of time dilation. It is also featured in the computer games Stars!, StarCraft, Eve Online, and Darkspace, the Starship Troopers universe, and other television shows including Red Dwarf. Warp drive, called 'FTL' in the Titan novels, isn't capable of instant travel between points at infinite speed, unlike the other fictional propulsion technologies hyper-, jump, and infinite improbability drives. Ships using warp drive differ from those using hyperdrive by traveling within a small created bubble of normal spacetime, rather than by entering a separate realm or dimension like hyperspace. Spacecraft at warp can interact with objects in normal space.
