A Stargate is a piece of Ancient transportation technology.

Overview

Function

The Stargate creates wormholes, charged matter steams of force that happen outside our dimension, capped at each end with an event horizon. When the Stargate activates it creates an unstable vortex, which can destroy matter in its radius. (SG1: "Solitudes", "Prisoners", "The Light") There needs to be enough room in front of the event horizon for the matter to be allowed to reintegrate. (SG1: "The Enemy Within") If enough excess energy is directed into the Stargate, the wormhole can redirect to another nearby Stargate to deposit any travelers. (SG1: "Solitudes") If something is positioned within the event horizon the Stargate will remain open for as long as it is possible (SG1: "Shades of Grey") Without a DHD or another dialing computer, a Stargate can only dial other gates within about 300 light years. (SG1: "2001") When an unstable vortex forms, the excess energy causes the memory buffer to be wiped. (SG1: "48 Hours")

Power

Stargates are giant superconductors capable of absorbing many forms of energy including heat, solar, nuclear and static energies. (SG1: "The Torment of Tantalus") When disconnected from a power source, a Stargate can retain enough energy to dial out once. (SG1: "Nemesis") If enough power is directed at the Stargate then a wormhole can be maintained for longer than usual. (SG1: "Watergate", "Chain Reaction") The Stargate can absorb a lot power but if its capacity is exceeded, the Stargate is charged and can explode. (SG1: "Redemption, Part 1")

Durability

A Stargate is capable of surviving in tact from a direct hit by a meteor and the heat and friction caused by atmospheric entry. (SG1: "A Hundred Days", "Small Victories", "Watergate") They can survive being surrounded by superheated plasma but cannot survive in the fusion reaction of a star. (SG1: "Chain Reaction", "Exodus")

Transit

The Stargate will convert matter into energy to transmit it to another Stargate that reconstructs it into matter again. (SG1: "Red Sky") Energy can be transmitted through the Stargate including radiation, radio signals and Ascended beings, and some energy can be sent both ways through an active Stargate. (SG1: "Chain Reaction", "Maternal Instinct") The Stargate uses density, molecular structure, and the force being exerted on the event horizon to determine if something is trying to pass through. (SG1: "Watergate") Objects exit at the same velocity that the enter, but can exit at different speeds due to various circumstances such as unstable power sources. (SG1: "Upgrades", "Children of the Gods", "Red Sky", SGU: "Air, Part 1") The gravitational and time dilation effects of a Black hole can be transferred through a Stargate. (SG1: "A Matter of Time") If the Stargate shuts down as energy is being transmitted, it will be broken down to its base form, such as elements, in the area where the wormhole was passing. (SG1: "Red Sky")

When a Stargate receives an energy signature it is stored in a memory buffer temporarily, to make sure it received the whole signature, before it is reintegrated. (SG1: "48 Hours") The buffer can be forced to store a signature and then send it to another planet. (SG1: "Ex Deus Machina") It is possible to force the Stargate to create an event horizon to allow it to reintegrate anything stored in the buffer. (SG1: "48 Hours") The Stargate will only transmit things in discrete units and won't transmit anything if the item hasn't completely entered the event horizon. (SGA: "Thirty-Eight Minutes") The Stargate can connect to multiple Stargates at once and can transmit forms of energy through it. (SG1: "Reckoning, Part 2") A Stargate can only reach other Stargates within a 90,000 light year radius unless additional power is supplied. (SGA: "The Return, Part 1") Destiny-era Stargates have a much smaller range. (SGU: "Lost") Something passing into an incoming wormhole's event horizon appears to destroy it. (SG1: "A Hundred Days")

Chevrons

See: Chevron

The Stargate has nine chevrons on it which light up depending on the actions being undertaken. The top most chevron will light up temporarily when an Glyph is selected and another chevron will light up to denote which number in the address is being dialed. When a connection is made the top seven chevrons stay lit as the wormhole is active. (SG1: "Children of the Gods", "Solitudes") An eighth chevron is needed to dial addresses in other galaxies. (SG1: "The Fifth Race")

Glyphs

See: Glyph

The Stargate has 39 glyphs on the inner ring. (SG1: "Touchstone")

Point of Origin

See: Point of Origin

A special symbol among the glyphs is the Point of Origin that is required as the final symbol when dialing other planets. (Stargate, SG1: "The Fifth Race")

Dial Home Device

See: Dial Home Device

The Stargate can be controlled by the Dial Home Device. (SG1: "Children of the Gods")

Versions

Milky Way

The Milky Way has a network of Stargates in it. (SG1: "Children of the Gods")

Pegasus

Pegasus has a network of Stargates in it. (SGA: "Rising")

Tollan Stargate

See: Tollan Stargate

The Tollan, working with the Nox, developed their own Stargate which was placed on Tollana. (SG1: "Pretense")

Orlin's Stargate

See: Orlin's Stargate

The de-ascended Orlin constructed a small, single-use Stargate on Earth using Earth materials and technologies . (SG1: "Ascension")

Destiny Stargates

A Stargate aboard Destiny, as well as those deposited on planets from the Seed ships are a much earlier version. The entire Stargate rotates around until the wanted symbol is at the top where it will light up. The Stargate on Destiny has an orb at the top and after it deactivates, two vents at the sides will release a gas. (SGU: "Air, Part 1") The Stargates on planets have a large base they are placed into. Ancient Remotes are needed to dial these Stargates. (SGU: "Air, Part 3", "Sabotage") These Stargates have a much smaller range than later versions. (SGU: "Lost", "Intervention") These Stargates are less durable than later versions, capable of being destroyed with less effort. (SGU: "Common Descent")

Etymology

The Stargate is known by various names from different cultures:

History

The first idea for the Stargate was thought up by the Alteran Amelius who sketched a basic concept for it the night before his people left Celestis. (Stargate: The Ark of Truth) The Stargates were created by the Ancients who deposited them on many different worlds in the Milky Way and even gave one to the Asgard who put it on the planet Othala in the Ida galaxy. (SG1: "The Fifth Race") The Seed ships were launched to gather resources to manufacture Stargates and place them on planets in the path of Destiny. (SGU: "Air, Part 2") The Goa'uld used the Stargates to bring humans from Earth to other planets. (SG1: "Solitudes", "The Torment of Tantalus") The Stargate on Edora was hit by a meteor and it survived intact but the meteor caused the Naquadah in the soil to form a hardened Iris over it. (SG1: "A Hundred Days") When the DHD on P3X-116 was destroyed, it cut off power to the Stargate and Teal'c was trapped in the memory buffer due to their not being enough power to reintegrate him. He was later removed by creating an event horizon and allow him to be reintegrated. (SG1: "48 Hours")
