This article deals with the stargates that feature as a central part of stories set in the Stargate science fiction universe. They are uniformly depicted as large, usually vertical metal rings.

They first appeared in the 1994 film Stargate, directed by Roland Emmerich, and then were redesigned to subsequently appear in the television series Stargate SG-1 and its spinoff Stargate Atlantis (as well as the animated series Stargate Infinity).^[2] The stargate is the central plot generator of these productions, allowing for stories focused on a small team of protagonists exploring other planets and meeting other races on foot, rather than the more prevalent, grandiose "space opera" of interstellar starships seen elsewhere in science fiction. Later in the series stargates are also used for more casual transportation to other worlds and other bases of the SGC. Stargates are also often used as shortcuts for small spacecraft to fly through such as the Goa'uld Needle Threader, Lantean Puddle Jumper, and Wraith Darts.

In the fictional Goa'uld language, the stargate is referred to as the Chappa'ai (Cha-Pa-Eye). This word for the gate is also used by many of the inhabitants of the Stargate worlds, no doubt brought to them by the Goa'uld System Lords. Stargates are referred to by the Ancients as "Astreaporta". The Gates have also been referred to as the "Ring of the Gods", "Circle of Standing Water", "Doorway", "Stone Ring", "Gateway", "Annulus", "Ring of the Ancestors", "Circle of Darkness", and "Portal" (by characters of less advanced societies that fear or revere the device), and even (in a deliberate self-parody) as "The Old Orifice."^[3] The Goauld language is a fictional language spoken by the Goauld and Jaffa from the television series Stargate SG-1. ...

Stargates are marked out by nine chevrons spaced equally around their circumference (See the schematic diagram below), and 39 symbols displayed on an inner ring on gates in the Milky Way Galaxy, or 36 on those in the Pegasus galaxy (it is unknown how many symbols feature on gates in the Ori home galaxy or on those in Ida) .^[2] They are typically 22 ft (6.7 m) in diameter, 64,000 lb (29,000 kg) in weight,^[4] and held to be made of the fictional heavy mineral "Naqahdah".

In the mythology of the canon, their creators were an alien race known as the Ancients,^[2] who called them the Astria Porta in their language, and scattered them on a variety of planets and moons, throughout the Milky Way and other galaxies millions of years ago. The Alteran who invented the Stargate was named Amelius, who incidentally was also the inventor of the Ark of Truth. Collectively, these comprise what is called the "Stargate Network", as they facilitate interaction between distant planets. The plot of Stargate effectively begins when the United States Air Force discovers how to use one of these devices that was discovered on Earth and begin to explore the galaxy through its use.^[1] Although stargates are present on many planets, most of the races they encounter are relatively primitive, and view the gates as no more than divine, sacred or terrifying relics, as evidenced by such names as "Ring of the Gods" or "The Great Ring".^[5]^[6]^[7] Canon, in the context of a fictional universe, comprises those novels, stories, films, etc. ...

Conceptual origin

The basic notion of the stargate concept is to have at least two mechanical devices (stargates) in two distant positions, such that, when active, the rings of each become similar to a physical, singular gateway or door-frame between the two locations. The concept was developed by the writers of the feature film Stargate, Dean Devlin and Roland Emmerich. Similar devices had been seen in previous fiction, but their complete conception as seen in the film was quite original — though there has been contention as to whether they plagiarized the idea from a previous script submission.^[8] Image File history File links SG-1_True_Science_Wormhole. ...

The idea of a "portal" for travelers has been seen often throughout the history of both fantasy and science fiction, often taking a similar form, a device or magical object shaped as a regular or irregular closed geometric form filled with a water-like, rippling puddle that represents the boundary point between the two locations. The stargate picks up heavily on this conception, emphasizing the "watery puddle" for the sake of an alien mystique.

Much of the inspiration for the functioning of the device is drawn heavily from theoretical astrophysics, particularly that of black holes and wormholes, a staple of science fiction, often used to create "shortcuts" through space. Although these may exist in reality, it is not widely held to be true that any such phenomenon could safely transport a human being,^[9] as such wormholes would most likely be created by excessive gravity (e.g. from a black hole) which would destroy any potential traveler.^[10] In Stargate however, this is circumverted by transporting a traveller through as an energy signature, and reintegrating him at the other end.

Surrounding plot

The Stargate film begins in 1928, when the titular alien device is first discovered and unearthed at Giza, with a young Catherine Langford watching as her father, the archaeologist who found it, directs its unearthing. It quickly skips to the "present day" (1994), in which an unsuccessful archaeologist Daniel Jackson is giving a lecture about his outlandish theories that the Great Pyramid of Giza was not built by the pharaoh Khufu. After he is laughed away, an aged Catherine Langford meets with him, and recruits his egyptological talent, taking him to a top-secret military base at Creek Mountain, where he is instructed to decipher the unique Egyptian hieroglyphs present on a set of cover-stones. He realizes that the indecipherable glyphs are in fact not words but images of constellations, such that by identifying 6 of them a position in space can be extrapolated. He is then shown the stargate itself, uses his new understanding to identify the 7^th symbol (the point of origin allowing a route to be extrapolated), and the gate is opened for the first time.

Because thousands of combinations had been previously tried and had failed, it was believed at the time that only two stargates existed, connecting Earth and the planet Abydos, which was visited in the film. At the beginning of the Stargate SG-1 series, however, a large set of additional valid coordinates were discovered engraved in ruins on Abydos. Because the coordinates pick out stars, and because time leads to stellar drift, other addresses were impossible to dial until Samantha Carter reworked the dialing system on Earth to account for this movement. After this, a massive network of possible connections suddenly became available. Even more addresses were later uncovered by Colonel Jack O'Neill from a repository of Ancient knowledge.

The alien race encountered in the original movie is later developed in SG-1 as the Goa'uld, the dominant evil power in the Milky Way. The leaders of this race, the System Lords, pose as gods and use the stargates to transport slaves between worlds. This has resulted in a large number of planets throughout the galaxy sporting human life, often in civilizations more primitive than Earth. The majority of these civilizations, descended from former Goa'uld slaves, treat the stargate as a religious relic, often as a source of long-forgotten fear and evil.

For most of the run of Stargate SG-1, Earth was under constant threat from the Goa'uld, and is no match for their superior technology. In the face of this threat, the US Air Force established a top-secret base, the SGC (Stargate Command), as a frontline defence. Multiple teams are formed and sent on missions through the stargate, their primary objective being exploration, and through it the discovery of intelligence, technology and allies to help the fight against the Goa'uld. The primary team is called SG-1, and the series follows their adventures. Stargate SG-1 (often abbreviated as SG-1) is a science fiction television series, part of the Stargate franchise. ...

For a long time it was thought that the Goa'uld were the builders of the Stargate Network, but it was later discovered that they had merely made use of the relics left behind by a different and extinct race, the Ancients. At the climax of SG-1's 6th season, Daniel Jackson discovers that the Earth myth of Atlantis is in fact founded upon the Lost City of the Ancients, and Season 7 is spent trying to locate it. At the beginning of the show Stargate Atlantis, which coincides with the beginning of SG-1's 8th season, the city is found in the Pegasus Galaxy, and 8 chevrons are dialed to send an expedition there on what could be a one-way trip. It is there that they discover a new network of stargates, and are plagued by the nemesis of the Ancients, the Wraith. During the events of The Ark of Truth it is revealed that the pre-ascended Ancient known as Amelius originated the concept of the Stargate and wormhole travel.

Internal names

The Ancients placed stargates on thousands of worlds across the galaxy, but the gate network was open to use by all, and continues to be a convenient form of travel for many races. Some races, such as the Goa'uld, grew their ways of life around the gates, which became integral to the functioning of their culture. The Goauld (pronounced go-ah-OOLD , commonly GOOLD, or go-OOLD) are a fictional parasitic alien race in the science fiction television series Stargate SG-1 universe. ...

In turn, most races developed their own names for the stargates. The Ancients called them Astria Porta, a Latin-esque word for "Star Gate"; in Latin, it would really be either porta stellae or porta in astria. The Goa'uld and Jaffa call them the Chaapa'ai. The English word "stargate" is a direct calque of Chaapa'ai, and Chaapa'ai is itself a calque of Astria Porta. The Wraith call the Stargate the Portal.

Although stargates are present on many planets, most of the races which inhabit them are relatively primitive, and view the gates as no more than divine, sacred or terrifying relics, as evidenced by such names as "Ring of the Gods" and "Circle of Darkness".^[5]^[6]^[7] In the Pegasus galaxy, villagers know them as Rings of the Ancestors and variations thereof. They are also commonly referred to as "the ring", "the annulus", or simply "the gate". An annulus In mathematics, an annulus (the Latin word for little ring, with plural annuli) is a ring-shaped geometric figure, or more generally, a term used to name a ring-shaped object. ...

Operation

The film Stargate rushed very quickly over how a stargate actually works and is operated, but the subsequent television shows go into this area in a great amount of detail. In SG-1, it is explained that a stargate's destination is not fixed, but is singled out by a process known as "dialing".^[11] Once a destination is selected by the traveler, the stargate generates a wormhole between itself and a complementary device at the destination, by being supplied with a threshold amount of raw energy.^[12] Objects in transit between gates are broken down into their individual elemental components, and then into energy as they pass through the event horizon, and then travel through a wormhole before being reconstructed on the other side.^[1] For other uses, see Wormhole (disambiguation). ... The periodic table of the chemical elements A chemical element, or element, is a type of atom that is defined by its atomic number; that is, by the number of protons in its nucleus. ...

Dialing

Each location served by a stargate has its own unique "address", which is a combination of seven or more non-repeating symbols appearing on the dialing stargate.^[13]^[11] By "dialing" these symbols in the correct order, the traveler selects a destination. Image File history File links Download high resolution version (1012x569, 72 KB) Summary The seventh chevron on a Stargate (device). ... Image File history File links Download high resolution version (1012x569, 72 KB) Summary The seventh chevron on a Stargate (device). ...

The show is consistent with the mechanics of address-dialing. The process involves associating a unique symbol of the inner ring to each of at least the first seven of the chevron on the outer circumference. The main "address" is invariably dialed first, and the last symbol being the "point of origin" " representing the gate being used, which acts as the final trigger for the completion of the address sequence.^[14] As each symbol is dialed, the chevron is said to "engage" or "encode" and usually responds by lighting up or moving. When the final symbol of an address is dialed, that chevron is said to "lock" and the wormhole opens (this terminology is arbitrary and often interchangeable, but preferred by the recurring character Walter Harriman).^[14] If the address is incorrect or does not correspond to an existing or otherwise functional stargate, the last chevron will not lock, and all of the chevrons will disengage.^[12] For other uses of this name see Walter Harriman (disambiguation). ...

Addresses

The symbols used to comprise addresses are actually pictorial representations of star constellations. By identifying six constellations in space, a single point can be extrapolated that corresponds to the destination desired.^[1] It is assumed by the show that this is enough to identify the position of any stargate within a galaxy. The symbols dialed are often referred to as "coordinates", and are written as an ordered string; for example, this is the address used in the show for the planet Abydos:

(corresponding to the constellations of Taurus, Serpens Caput, Capricornus, Monoceros, Sagittarius and Orion). As explained by Dr. Daniel Jackson in the movie, the stargate requires seven correct symbols to connect to another stargate. As shown in the picture opposite, the first six symbols act as co-ordinates, creating three intersecting lines, the destination. The stargate uses the seventh symbol as the point of origin allowing one to plot a straight line course to the destination. Image File history File links Cropped. ...

Eight-symbol addresses were introduced in "The Fifth Race", opening up new plot lines by connecting stargates to different galaxies. The additional symbol acts as a type of "area code".^[15] Such connections, in comparison to seven symbol codes, required substantially more energy to complete a functional wormhole — much more than any standard dialing method can provide. Opening an intergalactic wormhole has been shown to require large amounts of power compared to a regular wormhole. This has been generated in a variety of ways in different episodes, although the main way is using a Zero Point Module (ZPM).^[16]^[17]^[15]^[18] The Fifth Race is an episode of the science fiction television series Stargate SG-1. ...

The show has never featured a nine-symbol address, so the purpose of the ninth chevron is unknown. However, Robert C. Cooper has stated that the purpose of the ninth chevron will be revealed in the upcoming series, Stargate Universe.^[19] One of the purposes proposed for the new series is that the ninth chevron connects it with a Ancient ship that seeds stargates throughout the galaxy, and was abandoned after the ancients ascended. It is unknown if this will be the final idea.^{[original research?]} The extra chevrons are so rarely used that stargates are often seen with those two chevrons embedded within the stone platforms that hold many of the gates upright (see the image at the top of this article). This has often led to the misconception that a stargate only has seven chevrons.^{[original research?]} Robert C. Cooper is a Canadian writer and producer. ...

Dial-Home Device

There are a handful of methods used in the shows to dial a stargate, and the most common is with the use of a Dial-Home Device. Almost always referred to as the "DHD" for short, it is depicted as a pedestal-shaped device with a round inclined control panel on top, consisting of two concentric circles of "keys", and a translucent red (Milky Way) or blue (Pegasus) hemisphere in the center; the keys represent the symbols on the rim of the stargate. By pressing these keys a traveler builds an address. The central hemisphere serves as an "Enter" key to activate the stargate once a destination has been dialed. In the Milky Way, the Dial-Home-Device contains 38 of the 39 symbols on the stargate, meaning there is always a missing glyph on each DHD. This missing glyph however is not the point of origin for the planet. It has been confirmed that the missing glyph on numerous DHDs differs based on how each stargate is positioned on different planets. The glyph that is hidden under the pedestal of the stargate, unseen along with the two chevrons, cannot be dialed by the DHD. This states that only certain addresses can be reached in certain positions in the galaxy. The only way to intervene and reach all destinations in the Milky Way is to manually dial the gate, or use an alternative dialer, such as the one at the SGC.^[20] In the science fiction television Stargate universe, a DHD (for Dial-Home Device) is an Ancient machine used to control a stargate. ...

Originally, carriage return was the term for the key, lever, or mechanism on a typewriter that would cause the cylinder on which the paper was held (the carriage) to return to the left side of the paper after a line of text had been typed, and would often move it...

The show makes it clear that every stargate originally had its own DHD, located directly in front of the gate and facing it.^[12] Over time, however, some DHDs have been damaged or lost. This has been the source of plot-difficulties for the protagonists on several occasions, as it is still possible to travel to a stargate that lacks a DHD, meaning that dialing home again will be much more difficult, if not impossible. One of the primary functions of the MALP that precedes an SG team is to confirm the presence of a functioning DHD.^[12] A MALP enters a stargate A Mobile Analytic Laboratory Probe, or MALP, is a device in the fictional Stargate universe, though based on the real concept of an Unmanned Ground Vehicle. ... In the science-fiction universe of the Stargate SG-1 television series, the SG military-team designation denotes a team that is a part of the Stargate Program, while the number following the designation is to distinguish between separate Stargate teams. ...

The Wormhole

Once an address is dialed, the gate is said to have created a "stable wormhole" between itself and the gate dialed. The creation process is depicted with great consistency, and hence has become one of the defining motifs of Stargate, at times being central in both the SG-1 and Atlantis title sequences. It involves the generation of the "puddle of water" portal which lasts roughly 2 seconds, and is completed by the ejection of an unstable energy vortex resembling a surge of water or quicksilver. The vortex is portrayed as a symbol of the stargate's power, invariably causing characters to be awed.^[21] Any matter which comes into contact with the vortex is destroyed, as is dramatically demonstrated by a pair of smoking shoes in the episode "Prisoners".^[22] Image File history File links Kawoosh_side. ...

Power for the wormhole can be drawn from both the point of origin (the dialing stargate's power source) and the destination.^[23] One of the most basic and repeated axioms of Wormhole Physics, the (fictionalized) field of study pioneered by the character Samantha Carter, is that unless an extraordinary amount of energy is being generated at either end, a wormhole can only be maintained for 38 minutes at a time.

The actual portal of a stargate appears inside the inner ring when an address is correctly dialed. This has the appearance of a vertical puddle of water which represents the "event horizon" in the show. In non-fictional parlance, an event horizon is the perimeter around a black hole or wormhole through which once one had crossed, the gravitational pull of the singularity would be too strong to overcome. The wavering undulations characteristic of water are supposed to represent the "fluctuations in the event horizon".^[11] This puddle may then be entered (usually accompanied by a water-like sound), and the traveler will emerge from a similar pool at the destination stargate. The show makes it clear that transit is strictly one-way; an attempt to travel "backwards" causes the traveler to be destroyed^[24] (though during the episode "New Ground" and in the first episode a man partially puts his hand through the event horizon of the destination gate and pulls it back with no apparent issues^[25] However, as matter is only transmitted through a stargate once the whole object has passed the event horizon (except in the same "A Hundred Days" episode where Teal'c dangled from a rope secured to a ceiling on the other side) the stargate would not have started to try to deconstruct him, instead waiting until he was entirely inside). Additionally, the outgoing gate is invariably entered from the same side as the unstable vortex present during stabilization of the wormhole.

Passage through a stargate is usually accompanied by a visual effect of shooting through a tunnel in space, though it is just meant to be a visual aid. The representation of the transit is sometimes almost instantaneous, and other times it appears to last up to 20 seconds. This is thought to be just a representation of how it might look. Since they are disintegrated, it would be impossible to truly see the inside of a wormhole or travel through it.

The actual time the travel takes on average 6 seconds. Novice travelers often emerge from the gate trembling as if they've been on a "roller coaster ride", and although it is often omitted later in the series, they also experience the sensation of being "frozen stiff."^[11] The character Charles Kawalsky compares stargate travel to pulling "out of a simulated bombing run in an F-16 at eight plus g" because of the energy going through the wormhole at such speed and then being "reintegrated".^[11] In other episodes, however, gate travel is superficially no different to stepping through a doorway.^[26] This has since been explained as problems with the man-made interface on the Earth gate, and has mostly been fixed over the years of stargate operations.

The visual effect resembles a spinning wispy tube, and was in Season 9 (and the first season of Atlantis) revamped to resemble a misty tunnel lit by shooting rings of light (almost looking like other stargates in the network).

Known statements about wormhole physics

As portrayed in the fictional universe of Stargate, wormhole physics is a field of study that describes the functioning of stargates and wormholes. It was pioneered by Samantha Carter. In the episode "Upgrades", possessing super-human abilities Samantha Carter wrote an entire book on the subject, claiming she had been wanting to write it for a long time previously but had never been able to find the time as it was such an incredibly complex subject. A fictional universe is an imaginary world that serves as the setting or backdrop for one or (more commonly) multiple works of fiction or translatable non-fiction. ...

Complexities of function

Both Stargate SG-1 and Stargate Atlantis introduce complicated facets of stargates to contrive more interesting plotlines. Some of these have been developed into integral parts of how stargates function.

Matter transmission

When an object passes through the event horizon (the "puddle"), it is not immediately transferred to the destination stargate, but rather the portion that has passed through is dematerialized and held in a "hyperspatial buffer".^[29] An object that hasn't completely passed through the event horizon may be pulled out again,^[29] and its atoms will rematerialise from the buffer as it is extracted. The gate does not begin transmitting an object until it has entirely passed through the event horizon. This ensures that only complete objects are transferred. Objects in the buffer remain in a state of suspension. This has been used to "store" people in medical need,^[29] but this is a dangerous maneuver, since any disintegrated matter in the buffer "ceases to exist" if the wormhole shuts down before the signal is transmitted.^[30] Furthermore, each time the gate is activated the buffer is wiped clean to receive new information.^[31] If the control crystal of a connected DHD is removed then an event horizon will form without establishing a wormhole, allowing any memory stored in the stargate to be reintegrated.^[31] Image File history File links Download high resolution version (1008x564, 267 KB) Summary From Stargate SG-1. ...

In computing, a buffer is a region of memory used to temporarily hold output or input data, comparable to buffers in telecommunication. ...

Several facets of the stargate are necessary for it to function as a useful personnel transporter. Matter emerging from a stargate retains any kinetic energy it had while entering, so a person running into one stargate will hit the ground running upon emerging from another. (Weapon projectiles also maintain their trajectory upon transit- a bullet fired through a stargate is just as dangerous as it would be otherwise) Also, the transmitting stargate does not allow the air molecules of the local atmosphere to pass through. The show explains that the stargate differentiates between objects attempting to pass through the event horizon and things that would naturally exert pressure, such as water, air, lava, etc.^[27] The cars of a roller coaster reach their maximum kinetic energy when at the bottom of their path. ...

Gate obstruction

A wormhole is prevented from forming if a significant obstruction is present inside the stargate's ring. Consequently, it is fairly common for stargates to be semi- or permanently sealed by burying them, invalidating that stargate address.

Image File history File links Download high resolution version (1024x576, 99 KB) Summary From Stargate SG-1. ...

Another means of controlling travel through a stargate is by placing a barrier a minuscule distance (less than three μm, in the case of the Earth's iris) from the event horizon,^[30] which allows the wormhole to form but prevents the reconstitution of matter upon arrival through the gate. In other words, a connection can be made but any matter trying to exit the gate will not regain its original structure, and hence will be annihilated. The iris on the Earth stargate and the shield on the Atlantis stargate perform this function, and have been seen to be used as an effective defensive precaution, whilst still allowing radio communication through the open wormhole. The SGCs Stargate with the Iris closed In the sci-fi television show, Stargate SG-1, the iris is a large, metal protective device that opens and closes over Earths Stargate. ... Aerial view of Atlantis. ...

Iris-type barriers also suppress the formation of an unstable vortex by not allowing the matter to form. Such barriers, however, are not the only way to prevent the vortex. Several aliens, including the Asgard and the Nox have demonstrated the ability to open a wormhole without the effect forming (Both races were allies of the Ancients, and may possess better knowledge of the stargate than other races). Also the Tau'ri in the future 1969 (Stargate SG-1).

Power source

Power is always required to establish an outgoing wormhole, and is usually supplied by the DHD, but any stargate can receive a wormhole whether it has a power supply or not; the dialing gate is the one that supplies power to both. In a few cases, stargates have been dialed "manually" when more sophisticated means were not available. This was accomplished by providing sufficient raw power to the gate and then rotating the symbol ring by hand to lock each chevron.^[22] Power can be fed directly into the Naqahdah that comprises the gate; power harnessed from lightning strikes has been shown to be sufficient.^[12] The stargate that establishes an outgoing wormhole determines how long the wormhole is held open, and can generally close the wormhole at will. Under some conditions, a gate only needs enough power to connect briefly, then the receiving gate can provide enough power to maintain the connection.^[23] The same is true if the outgoing gate loses power while transmitting; if the incoming gate has a DHD, it will take over powering the gate until reintegration is complete. The fictional Stargate setting contains a number of elements and other compounds unique to it, as well as fictional properties for real elements and compounds. ...

Secondary gates

Some planets are known to possess "secondary" or "backup" stargates.^[32] The second stargate is normally inactive, with the primary stargate (defined by the presence of a functioning Dial-Home Device) receiving all incoming wormholes.^[27] If a stargate experiences a power surge while an outgoing wormhole is open, the other end of the wormhole has been observed to "jump" to the next closest gate in the network. (The effect can also be used as a defensive measure, as seen in the episode "Prototype" or to close a connection with the receiving stargate as demonstrated in the episode A Matter of Time). In the case of a planet with two gates, the closest is the inactive secondary gate. This scenario occurred in SG-1's first season, and resulted in a second gate being discovered on Earth, located beneath the ice of Antarctica.^[32] Image File history File links Download high resolution version (1024x576, 69 KB) Summary From Stargate SG-1. ...

The Antarctic gate was later revealed to have originally been the primary stargate on Earth, built by the Ancients. It could in fact be the first stargate ever built.^[33] The stargate originally used in the SGC, found in Giza, was brought to Earth, by Ra, from another planet. Since stargate addresses correspond to planetary locations and not individual gates, the new gate inherited the same address as the one in Antarctica. Because the Antarctic gate had been abandoned millennia earlier by the Ancients and no longer had a connected DHD, Ra's gate became the primary.

In the episode "Nemesis", SG1 transports the stargate from Stargate Command onto a crashing spaceship in order to escape. The gate is replaced at the SGC by the Antarctic gate. The original gate survives the crash, however, and the Russian military takes possession of it to conduct their own off-world travel. Because they were also in possession of a DHD (not found in the original Giza dig but recovered from Germany after WWII), which they activated and deactivated at pre-defined times, they were able to selectively become the primary gate. Using a strict schedule for returning teams, they were able to avoid detection by the US Air Force for some time.^[27] Nemesis (Part 1 of 2) is the Season 3 finale episode of the science fiction television series Stargate SG-1. ...

In Redemption, the second stargate was destroyed by Anubis. In order to continue their stargate program, the US Air Force took on loan the Giza stargate from the Russians at a hefty price, and this gate is now the only one left on Earth.

The stargates themselves are extremely resistant to damage or destruction: in one case, a stargate survived a direct hit from a meteor,^[24] whilst another was still capable of creating a stable wormhole while on a planet near a newly-formed black hole.^[28] A stargate has also been seen to continue functioning whilst entering a sun,^[34] though it was protected by a portable forcefield for a portion of its journey. In the SG-1 fourth season episode "Chain Reaction", the SGC sent a naqahdah-enhanced nuclear bomb to a planet whose surface had trace amounts of naquadah in its topsoil; the explosion destroyed the entire planet, yet the gate still remained open and intact.

Exceptions

Under normal circumstances, a wormhole can only be maintained for slightly more than 38 minutes.^[29] However, on a few occasions, this limit has been surpassed. The first breach of this general rule occurred to Earth's gate connected to a planet in the proximity of a black hole.^[28] This method was also used intentionally by the Ori.^[35] The second incident occurred when energy-rich liquid beings maintained the power for a gate while a Russian vehicle had its transmitter stuck.^[27] The third exception happened when Anubis used a weapon made by the Ancients (or with their technology) to slowly feed energy to a stargate. The gate remained active and eventually exploded.^[4] Finally the fourth exception happened after Earth ordered an attack on the Asuran home planet, after it was discovered that they were building warships. The Asurans responded by sending a satellite containing a stargate to Lantea, which activated and a powerful beam came through hitting Atlantis' shield. The expedition had hoped that the stargate would shut down after 38 minutes, but, as Dr McKay stated, the Asurans had an unlimited number of zero point modules, with that amount of energy at their disposal they could hold the stargate open indefinitely.^[36] The Ori (pronounced )[1] are fictional characters in the American science fiction television series Stargate SG-1. ... The Asurans are a fictional race in the science fiction series Stargate Atlantis that bear many similarities to the Replicators of Stargate SG-1. ...

Susceptibility

The stargate and its network is susceptible to computer viruses. In the episode Avenger 2.0 the entire stargate network is brought down by a virus created by Dr. Felger. Although not intentional the virus was altered by Ba'al to take the network down. It was previously unknown that each DHD does periodic correlative updates by dialing other gates in close proximity to one another. The updates were designed to compensate for stellar drift to thus maintain the proper coordinates. The stargate at the SGC uses a human developed "Dialing Computer" rather than a DHD which accounts for the lack of in depth knowledge regarding the DHD's. It is also what saved the network as the Earth stargate was the only gate unaffected by the virus because it has no DHD. Avenger 2. ...

Other uses

In several episodes of the series, the Stargate Network was used for a purpose other than interplanetary travel. In the plots in which these extra functions feature, they are almost always discovered by a fluke, and were not intended in the design of the stargates. Two such occurrences regard the stargate's interaction with time, such as "1969", in which the SG-1 team accidentally travels backward in time to the year 1969, as a result of the matter transmission stream passing through a solar flare. The character Samantha Carter intentionally uses this phenomenon in the episode "2010", where she uses advanced technology to predict a flare and send a message back in time. Time is also a factor in the episode "Window of Opportunity", when a scientist uses a failed time machine built by the Ancients to isolate a region defined by 14 stargates from the rest of the space-time continuum, causing a time loop. 1969 is an episode from Season 2 of the science fiction television series Stargate SG-1. ...

In several episodes, the stargate, and the cobbled-together dialing program utilized by the SGC, are nearly the cause of disaster. In the episode "Red Sky", the bypassing of a system error caused the stargate to introduce atoms of plutonium into the center of a star, causing the star to become unstable. In the episode "Ripple Effect", an unknown device and/or method was used to connect different realities and was reversed by use of an Asgard beam weapon.

Milky Way

A Milky Way stargate has 39 inscribed symbols on the inner ring. When dialing, this inner ring rotates until the dialed symbol is aligned with the seventh chevron, at which point the ring pauses, the seventh chevron moves down and up, and the appropriate chevron in the sequence engages. In the Stargate SG-1 series, an engaged chevron glows red. In the original Stargate film, all of the chevrons use this motion, and none of them glow red.

However, not all points in space represented by these addresses have stargates, in fact, there are sufficiently few valid coordinate sets that randomly dialing the stargate is largely futile.^[11] If the person dialing does not know the point-of-origin symbol, there are many more possible combinations.

Because the gate on Earth was found without a DHD,^[1] the stargate team on Earth developed the technology to interface with the gate in order to power it and dial it by the use of computers.^[11] (Essentially an automated version of 'manual dialing'.) When using a DHD, however, each chevron is activated immediately upon entry of the symbols, without the inner ring spinning. This allows for a much faster dialing process.

Symbols at Giza

Depicted in the original film, the stargate found at Giza, Egypt was the first discovered by modern humans of Earth, in 1928. In SG-1 the same gate is used by the SGC for the first three seasons to explore other planets.^[37] It was discovered in the season seven finale, Lost City, that the glyphs have syllable pronunciations that allow a gate address to be spoken aloud as a destination name. This is how the planet Proclarush Taonas was named. The gate symbols are as follows: Gizeh is also a popular brand in Germany of cigarette rolling papers; see Mascotte (rolling papers). ...

Pegasus galaxy

In the spinoff series Stargate Atlantis, an expedition dials the 8-symbol address

from Stargate Command to travel to the Ancients' Lost City of Atlantis, located in the Pegasus Galaxy. They find that the Ancients seeded planets throughout the Pegasus galaxy with stargates too, but used gates of a slightly different design. As these gates were built at a later date than the original Milky Way network, they may be of more advanced design, however at this point the differences appear mostly cosmetic.

The alternative stargate design in the Pegasus galaxy is one of many things the producers of the shows employed to differentiate the sister shows SG-1 and Atlantis. Pegasus stargates are designed with blue chevron lights instead of red ones, and the address symbols are groups of small blue lights (rather than embossed figures) that light up sequentially instead of rotating. In SG-1 it is stated that the rotating section of the gate unlocks when sufficient power to dial has been fed to the gate, allowing manual dialing in case the DHD is damaged or not present, as on Earth. Image File history File links Pegasus_stargate_with_very_detailed_glyphs. ... Image File history File links Pegasus_stargate_with_very_detailed_glyphs. ...

Unlike the Milky Way gates, Pegasus gates are depicted with 36 symbols. 7 symbols are still required to dial an interplanetary address, adhering to the same constraints as a Milky Way gate. With 36 symbols, the Stargate Network in the Pegasus Galaxy has:

Thus there are fewer possible addresses in the Pegasus Galaxy, although it may still be the case that there are more stargates there if more of the possible addresses are utilized than in the Milky Way.

In a departure from the definitive "anywhere to anywhere" ethos of SG-1, the only stargate in the Pegasus galaxy capable of reaching stargates in the Milky Way is the one located at Atlantis.^[38] This is due to a special "control crystal" unique to the Atlantis DHD, without which a Pegasus stargate cannot encode its eighth chevron.^[38] Unlike any other known gates, the Atlantis Gate can also identify the point of origin of the gate that tries to dial in, and can block an incoming wormhole.^[38]

Some Pegasus stargates are orbital: they lead to open space, something never seen in the Milky Way. This is again a departure from the "personal travel" rather than "starship travel" ethos of SG-1, as these gates are used solely for space-faring vessels and never for humans. It is possible that the Ancients created these gates for localized travel to worlds where ground-based gate travel would be hazardous, either due to climate or atmospheric difficulties or due to native creatures. Another explanation is that the Wraith moved the stargates of certain planets and put them into orbit, to restrict access for the local human population, while still being able to send in ships for culling. Orbital gates are depicted without a DHD, being powered by three power nodes spaced equally along the outer ring (see image). In the show, Puddle Jumper vessels and Wraith Darts have built-in DHDs to explain how a craft would return through an orbital gate. Image File history File links A space-born Stargate in the Pegasus Galaxy, as seen in the episode Sanctuary (1x14), Stargate Atlantis. ...

Orbital stargates have sometimes been referred to as "Spacegates" by characters on the show, but this has not been stated to be an official term.

In "Irresistible",^[39] a plan was put in place to create a bridge of linked stargates in the void between the Milky Way and Pegasus galaxies to circumvent the need for a ZPM to effect travel between Atlantis and Earth (see McKay-Carter Intergalactic Gate Bridge below).

One concept directly ported from SG-1 to Atlantis, and that was the idea of an "iris" that allows wormholes to form but stops anything trying to emerge.^[18] The Atlantis stargate has a force field that serves the same function. As with SG-1, only the protagonists' gate has this capability, being the singular real defense they have against major attacks (thus allowing the shows to continue despite having insuperable enemies).

Symbols at Atlantis

The symbols depicted on the Atlantis gate again correspond to constellations, although in this case the constellations are fictional. The Atlantis glyphs do have names as was seen during a shot of McKay's laptop in the episode "Sateda" but most of their names are currently unknown. Sateda is an episode from Season 3 of the science fiction television series Stargate Atlantis. ...

Ori "Supergates"

In the ninth season of Stargate SG-1, the Ori were introduced as a new main enemy for the show. Ascended beings who belong to the same race as the Ancients, they come from an entirely new galaxy, and are described as being masters of technology and Wormhole Physics equal to the original gate-builders. While it is not known what the stargates in the Ori galaxy look like, their presence is implied by the fact that the Ori were able to send Priors (religious messengers) to the Milky Way through a stargate. The only clue as to their design is that the transport rings used in their galaxy are white and pearly, suggesting by analogy that their stargates are of this design as well.

On two occasions in the plot of Season 9,^[35]^[17] they attempted to create an enormous stargate of unknown measure but much larger than a Ha'tak, which was made of individual modules which were passed through a standard stargate, presumably from the Ori galaxy. The modules formed the ring of what the character Samantha Carter called a "Supergate". These gates lack an inner track and are instead dialed by preprogrammed data crystals inserted into a panel on the side. Carter hypothesized that by tapping the power in a black hole, a Supergate connection could be permanent.^[17] This was later confirmed in the episode The Pegasus Project. A standard gate was dialed from the Pegasus Galaxy to another placed in proximity to the Supergate. The Pegasus gate was then placed near a black hole, and then had a series of nuclear devices detonated at its event horizon. This resulted in the wormhole jumping to the Supergate, thus preventing any future use of it by the Ori. The Goa'uld word for the Supergate is Chappa'ko (Cha-Pa-Ko). This connection was broken in the season ten episode, "The Shroud." Daniel Jackson explained that a Mark IX warhead beamed behind the event horizon of the stargate located in the Pegasus Galaxy would destroy the stargate and sever the connection, thus making it possible to establish a new connection to another supergate.

In an apparent continuity error, while the supergate segments in "Beachhead" arrived through a planetary stargate, the segments of the supergate later observed in "Camelot" and subsequent episodes were many times larger than a conventional stargate could accommodate. Additionally, the second supergate's dimensions appear to increase between "Camelot" and "The Pegasus Project;" in the former, Ori warships pass through with little lateral clearance, while in the latter the supergate appears much wider than the Ori warship passing in front of it.

Orlin's homemade stargate

On the Stargate SG-1 episode "Ascension," the outcast Ancient, Orlin built a miniature stargate in Samantha Carter's basement. Its components included 100 pounds of pure raw titanium, 200 feet (61 m) of fiber optic cable, seven 100,000 watt industrial strength capacitors, and a toaster. This gate was hooked up to the main power supply of the house and only connected once, to Velona, before it burnt out. It has been mentioned once since, in the ninth season episode "The Fourth Horseman." Image File history File links Mini_gate. ... Image File history File links Mini_gate. ...

With the destruction of the original Tollan homeworld, the Tollan's stargate was lost. Their new homeworld, Tollana, had no original stargate, and with the assistance of the Nox, a new gate was built.

The Tollan gate was smaller and slimmer than the Ancient's stargates, and has a pale white color. However, it seems to lack a DHD, or even an inner track for manual dialing, suggesting more advanced remote dialing. Jack O'Neill sarcastically criticized the Tollan stargate, saying "Ours is bigger" in the episode "Pretense".

McKay-Carter Intergalactic Gate Bridge

During the third season of Stargate Atlantis, a project to place a chain of stargates in the void between the Milky Way and Pegasus galaxies was initiated, to allow rapid transit between Atlantis and the SGC without the need of a ZPM to power the stargate.^[39] At the time, only the Atlantis gate had a ZPM available, meaning that the return trip from Earth required a three-week journey in a hyperspace-capable Daedalus-class battlecruiser. To this end, stargates were "harvested" from the surface or orbit of uninhabited planets and deposited accordingly on both ends. When Atlantis' ZPM was depleted,^[40] the project took on an added urgency and was made operational shortly afterward. For other uses, see Milky Way (disambiguation). ...

The McKay-Carter Intergalactic Gate Bridge (named as such by its co-creator Rodney McKay, recognizing Samantha Carter for the original idea) consists of seventeen stargates from the Pegasus network and another seventeen from the Milky Way network. A macro program written by McKay and uploaded to the gates' operating systems before dialing causes them to store incoming matter in their buffers, forwarding travelers from one gate to the next along the bridge, rather than emerging from the gate that is initially dialed.

Travelers will then exit at the Midway Space Station, halfway between galaxies, which serves as a transfer point. There, they will then use the other gate network (and a second macro program designed for that network) to continue on to their ultimate destination: travelers from Atlantis would use a Milky Way gate to travel on to Earth and similarly, travelers from Earth would use a Pegasus gate to travel to Atlantis. Even with this, the travel time between galaxies is just slightly over thirty minutes, making it far more efficient than traveling by hyperdrive. This article is about a hypothetical method of space travel. ...

When the first test of the gate bridge was conducted, only the framework of the station had been completed, so a Puddle Jumper was used. The test was a complete success, and the bridge was declared operational. It was later revealed that, since the last gate in the bridge must dial the exit gate, normally either Atlantis or Earth, the macro can be rewritten to dial a different exit gate in the destination galaxy.^[41] The station has since been destoyed by the self-destruct after the infiltration of the Wraith, whether or not it will be rebuilt is unknown. In the Stargate science fiction universe, the Puddle Jumper is a small craft capable of space travel created by the Ancients. ...

Asuran Satellite Weapon

The Asurans had developed an eight-chevron variant of a stargate that was created as a satellite weapon. Its components included a shield generator, sensors and a hyperdrive allowing it to orbit its intended target. Once this is accomplished, a wormhole would be activated after which an intense red energy beam reaches out and strikes the target which, in this case, was the city of Atlantis. The beam would originate from an Asuran stronghold which would both power the satellites defenses as well as maintain an ongoing wormhole. The satellite also had the added effect of preventing stargate travel through the Atlantis stargate as long as the satellite maintained its connection to the dialing stargate, as both gates would be attempting to use the Atlantis coordinates. The satellite was able to receive the incoming wormhole from the Asurans, indicating that it could override the Atlantis stargate, the dominant stargate on the planet due to its being connected to a DHD. It appeared as a satellite with a stargate in the center of its form which allowed it to maneuver and, thus, direct the energy weapon.^[36] Image File history File links Size of this preview: 800 Ã— 453 pixelsFull resolution (960 Ã— 544 pixel, file size: 56 KB, MIME type: image/jpeg) This image is a screenshot from a copyrighted film, and the copyright for it is most likely owned by the studio which produced the film, and...

Making of the props

Two full stargate props were originally built for the SG-1 pilot "Children of the Gods", the second of which was reconstructed from the prop used in the film. They are made of steel and fiberglass, and are 22 feet (6.7 m) in diameter. The second prop is less detailed, and is used for exterior scenes; in the pilot it was used solely on the planet Chulak. The primary one, however, is quite sophisticated. It is fully automated, and capable of rotating and emitting light. This is achieved by the use of a specially-designed 22-foot (6.7 m) circular gear, which turns the inner ring on a precise pinion drive wheel, using an eight horsepower electric motor. The top seven chevrons emit laser pulses which are read by a sensor fed into a computer responsible for the gate's movement, which is consequently able to start and stop the rotation very quickly. This main prop is kept almost immovably at the permanent set of the SGC, at Bridge Studios, Vancouver.^[42] Theatrical properties, or props, are items used in stage plays and similar entertainments to further the action. ...

There are further stargate props which are no more than two-dimensional or semi-three-dimensional (jar-lid shaped) stargates, being more lightweight and easier to erect on location. These are always filmed front-on to preserve the illusion. If a shot involves the iris, this is added in post-production, as the mechanics of it opening and closing would be very difficult to build. However, when a stargate is filmed with just a closed iris (i.e. without it moving), a tangible prop is inserted into place. The SGCs Stargate with the Iris closed In the sci-fi television show, Stargate SG-1, the iris is a large, metal protective device that opens and closes over Earths Stargate. ...

The visual effects for Stargate SG-1 and Stargate Atlantis are predominantly produced by Rainmaker Digital Effects, a notable visual-effects studio. However, some effects, including the entire Ori battle sequence in the episode "Camelot", were done "in-house".^[43] The unstable vortex effect, both in the film and the early seasons of the series, on account of being "difficult to achieve" was generated only once and recorded from various angles; this recording was the same used for all gate opening shots early in the series.^[42] Rather than being a jet of water, it is actually the image of high-pressure air being blasted into a tank of water. The effect was achieved by mounting a jet airplane engine two feet above a water tank, and using its 180 mph (290 km/h) windstream to create the sufficient water displacement. In post production, the surrounding water was removed with computer editing, and the image of the air-jet pasted into the center of the opening stargate. This technique was only used for earlier episodes, and the effect was replicated digitally soon after to allow more flexibility in shots. Rainmaker Digital Effects, more commonly just Rainmaker is a special effects studio located in Vancouver. ... Camelot (Part 2 of 3) is the Season 9 finale episode of the science fiction television series Stargate SG-1. ...

To cut down on costs, the opening of a stargate is often just implied rather than shown, by a costless sound-effect followed by distinct lighting effects characteristic of light shining through water (as the event horizon is depicted). The DVD commentary for Stargate SG-1 explains that these effects are produced by reflecting light off a large sheet of aluminum.

Aluminum is a soft and lightweight metal with a dull silvery appearance, due to a thin layer of oxidation that forms quickly when it is exposed to air. ...

The stargate itself is nearly always filmed against a blue or green backdrop, not only making it easier to paste the vortex imagery onto the scene, but also facilitating the superimposition of the "event horizon ripple effect", which is entirely computer-generated. However, if a shot only involves an open wormhole without anyone stepping through it, the crew may choose to use a "practical puddle," which is simply a back lit screen placed in the gate displaying a video of the wormhole effect. This only works, however, on a darker set, as otherwise the projection will get washed out.^[44] On occasion, the stargate itself is also completely swapped out for a computer generated model, usually in cases where it is being moved, or is depicted in space. Series producer Robert C. Cooper explained that it often costs a lot to erect a stargate on location, and so in some cases offworld gates are also entirely a visual effect.^[45] The bluescreen setup. ...

Use of the term "stargate" in other works

The basic concept of a "stargate" did not originate with the movie Stargate. Andre Norton's 1958 novel Star Gate used the term, while the portal concept is a key plot device used in science fiction for decades prior to the film.

Since the introduction of the stargate on the big screen, authors Lynn Picknett and Clive Prince wrote The Stargate Conspiracy: The Truth About Extraterrestrial Life and the Mysteries of Ancient Egypt. The book details an alternative theory which associated the term stargate with Egypt's past: either the pyramid itself is a gateway to the stars (because of the shafts pointing to a star) or the building of Heaven on Earth based on geographical location of the great and outlying pyramids (see: Orion).
