Scotty, Beam Me Up - Gerry is Transported Using Star Trek Teleportation Machine

A transporter is a teleportation machine used in the Star Trek universe. Transporters convert a person or object into an energy pattern (a process called dematerialization), then "beam" it to a target, where it is reconverted into matter (rematerialization). The term "transporter accident" is a catch-all term for when a person or object does not rematerialize correctly.
