Transporter glitch aboard the Enterprise

A transporter is a fictional teleportation machine used in the Star Trek universe. Transporters allow for teleportation by converting a person or object into an energy pattern (a process called "dematerialization"), then sending ("beaming") it to a target location or else returning it to the transporter, where it is reconverted into matter ("rematerialization").

The transporter was originally conceived as a device to convey characters from a starship to the surface of a planet without the need for expensive and time-consuming special effects to depict the starship or another craft physically landing. Malfunctioning transporters are also often used as a plot device to set up a variety of science fiction premises.
