The Quantum Mirror is a device which allows people to travel into an alternate reality and was created by the Ancients.


The quantum mirror is activated by a control device and is possibly made of Naquadah. After activation, the device shows an alternate reality through the use of its mirror. If a person touches said mirror, they would be engulfed in energy and transported to their chosen reality. (SG1: "There But for the Grace of God")


There But for the Grace of God

Daniel Jackson discovers the Quantum Mirror.

Before its initial discovery by SG-1, the Ancients had constructed the device. (SG1: "The DVD Collection 6") It was found on P3R-233 by Dr. Daniel Jackson, who upon touching was transported through the Quantum Mirror into an alternate reality where he found that Earth was about to be overrun by a Goa'uld invasion force, which was led by an alternate Teal'c. Daniel discovered that his reality was facing the same threat and asked the alternate versions of several of his friends to help him return to save his own world, reasoning that it was impossible for them to save their reality but the information he had acquired in this universe - including the gate address that the invasion originated from could still be used to save his own reality. Just before the alternate Stargate Command was destroyed, Daniel escaped into his reality. Afterward, the mirror was transported to Earth and stored in Area 51. (SG1: "There But for the Grace of God")

A year later, an alternate Dr. Samantha Carter and Major Charles Kawalsky escaped their reality through the Quantum Mirror. When Dr. Carter began to suffer entropic cascade failure at the cellular level due to the presence of two Samantha Carters in one reality, Major General George S. Hammond and SG-1 decided that, to save the alternate Carter's life, they would free their Earth which had been taken over by Apophis' forces led by Teal'c. The General also ordered that, upon completion of the mission, the quantum mirror be destroyed. (SG1: "Point of View") The quantum mirror was eventually melted down at Area 51. When the outer rim of the mirror was destroyed, the singularity that was part of the mirror detached, closed in on itself and vanished. As the personnel at Area 51 had prepared for this, all the destroyed quantum mirror took with it was a small concrete bunker and a naquadah generator. (SGA: "Entanglement")

In 2006, when many different versions of SG-1 began to appear, Dr. Bill Lee regretted that the mirror was destroyed. In response, Lt. Colonel Samantha Carter notes that it would be impossible to use the mirror to return everyone to their exact realities due to the number of alternate worlds involved. (SG1: "Ripple Effect")
