Transwarp drive

Warp drive is a faster-than-light (FTL) spacecraft propulsion system in many science fiction works, most notably Star Trek. A spacecraft equipped with a warp drive may travel at speeds greater than that of light by many orders of magnitude. In contrast to other FTL technologies such as a jump drive or hyper drive, the warp drive does not permit instantaneous travel between two points but involves a measurable passage of time which is problematic to the concept. Spacecraft at warp velocity theoretically continue to interact with objects in "normal space". The general concept of "warp drive" was introduced by John W. Campbell in his 1931 novel Islands of Space.

Einstein's theory of special relativity states that energy and mass are interchangeable, thus, speed of light travel is impossible for material objects that weigh more than photons. The problem of a material object exceeding light speed is that an infinitely increasing amount of kinetic energy is required to attempt moving as fast as a massless photon. This problem can theoretically be solved by warping space to move an object instead of increasing the kinetic energy of the object to do so.

Warp drive is one of the fundamental features of the Star Trek franchise; in the first pilot episode of Star Trek: The Original Series, "The Cage", it is referred to as a "hyperdrive"/"time warp" drive combination, and it is stated that the "time barrier" has been broken, allowing a group of stranded interstellar travelers to return to Earth far sooner than would have otherwise been possible. The light speed time barrier shouldn't be confused with time dilation which occurs when approaching very fast speeds. Warp drive technology avoids time dilation.

The episode "Metamorphosis", also from The Original Series, establishes a backstory for the invention of warp drive on Earth, in which Zefram Cochrane discovered the "space warp". Cochrane is repeatedly referred to afterwards, but the exact details of the first warp trials were not shown until the second Star Trek: The Next Generation movie, Star Trek: First Contact. The movie depicts Cochrane as having first operated warp drive on Earth in 2063 (two years after the date speculated by the first edition of the Star Trek Chronology). By using a matter/antimatter reactor to create plasma, and by sending this plasma through warp coils, he created a warp bubble which he could use to move a craft into subspace, thus allowing it to exceed the speed of light. This successful first trial led directly to first contact with the Vulcans.
