Teleportation is the transfer of matter from one point to another, more or less instantaneously, either by alchemy, paranormal means, or through technological means. Teleportation has been widely utilized in works of science fiction. There is no evidence that such a phenomenon exists on the macroscopic level.

Apport is an earlier word used to describe much the same thing; bilocation is where an individual or object is supposed to be, or appears to be, located in two distinct places at the same instant in time (though "true" bilocation would be impossible due to the laws of quantum mechanics). The word "teletransportation" (which simply expands Charles Fort's abbreviated term) was first employed by Derek Parfit as part of a thought exercise on identity.

The word was coined in 1931^[1][2] by American writer Charles Fort to describe the strange disappearances and appearances of anomalies, which he suggested may be connected. He joined the Greek prefix tele- (meaning "distant") to the Latin verb portare (meaning "to carry"). Fort's first formal use of the word was in the second chapter of his 1931 book, Lo! "Mostly in this book I shall specialize upon indications that there exists a transportory force that I shall call Teleportation." Though Fort added, "I shall be accused of having assembled lies, yarns, hoaxes, and superstitions. To some degree I think so myself. To some degree, I do not. I offer the data."^[3] Fort suggested that teleportation might explain various allegedly paranormal phenomena, although it is difficult to say if Fort took his own "theory" seriously, or instead used it to point out what he saw as the inadequacy of mainstream science to account for strange phenomena.

[edit] Scenarios

One means of teleportation proposed in fiction is the transmission of data which is used to precisely reconstruct an object or organism at its destination. However, it would be impossible to travel from one point to another instantaneously; faster than light travel, as of today, is believed to be most likely impossible. The use of this form of teleportation as a means of transport for humans would have considerable unresolved technical issues, such as recording the human body with sufficient accuracy to allow reproduction elsewhere (i.e., because of the uncertainty principle), and whether destroying a human in one place and recreating a copy elsewhere would provide a sufficient experience of continuity of existence. The reassembled human might be considered a different sentience with the same memories as the original, as could be easily proved by constructing not just one, but several copies of the original and interrogating each as to the perceived uniqueness of each. Each copy constructed using merely descriptive data, but not matter, transmitted from the origin and new matter already at the destination point would consider itself to be the true continuation of the original and yet this could not logically be true; moreover, because each copy constructed via this data-only method would be made of new matter that already existed at the destination, there would be no way, even in principle, of distinguishing the original from the copies. Many of the relevant questions are shared with the concept of mind transfer.

Dimensional teleportation is another proposed means of teleportation. Often shown in fictional works, particularly in fantasy and comic books, it involves the subject exiting one physical universe or plane of existence, then re-entering it at a different location. This method is rarely seriously considered by the scientific community, as the currently predominant theories about parallel universes assume that physical travel is not possible between them.

A third proposed means of teleportation common in science fiction (and seen in The Culture novels and The Terminator series of films) sends the subject through a wormhole or similar phenomenon, allowing transit faster than light while avoiding the problems posed by the uncertainty principle and potential signal interference. In both of the examples above, this form of teleportation is known as "Displacement" or "Topological shortcut" (Scientific American)^{[citation needed]} which implies that this kind of teleportation may be similar in mechanism to time travel^{[citation needed]}. Displacement teleporters would eliminate many probable objections to teleportation on religious or philosophical grounds, as they preserve the original subject intact — and thus continuity of existence.

Teleportation by means of the mind or innate personal abilities are sometimes referred to as p-Teleportation, "psychoportation", or "jaunting"; named after the fictional scientist (Jaunte) who discovered it in The Stars My Destination (originally titled Tiger! Tiger!), a science fiction novel by Alfred Bester. This method could hypothetically work through any of the mechanisms proposed above, but is usually portrayed in fiction as displacement-type or dimensional teleportation to simplify its use in the story.
