139-494: Black holes in fiction • Portable hole • Teleportation in fiction • Wormholes in fiction • Stargate • Warp drive • Hyperspace • Time travel in fiction A Stargate is a fictional Einstein–Rosen bridge portal device within the Stargate fictional universe that allows practical, rapid travel between two distant locations. The devices first appeared in the 1994 Roland Emmerich film Stargate , and thereafter in

278-438: A culturally sensitive manner, sometimes siding with their interests above those of the military back on Earth. Daniel seems more akin to a pseudo-archaeologist than a scientist. Pseudo-archaeology operates, generally, outside of the empirical and analytical methods of the profession of archaeology, and often is associated with claims of extraterrestrial life, magic, and other phenomena. In the fictional universe of Stargate, Daniel

417-484: A hypervelocity star on a trajectory towards the Solar System . Says The Encyclopedia of Science Fiction , "the immense black hole at the galactic core has become almost a cliché of contemporary space opera " such as Greg Egan 's 2008 novel Incandescence . The pulp-era motif of black holes posing danger to spacefarers resurfaced decades later following the popularization of black holes in fiction. In

556-599: A telepathic scream from a being falling into a black hole thus becomes drawn out for eternity. Similarly, a spaceship appears forever immovable at the event horizon in Brian Aldiss 's 1976 short story " The Dark Soul of the Night ", and in Frederik Pohl 's 1977 novel Gateway , an astronaut is wracked with survivor's guilt over the deaths of his companions during an encounter with a black hole, compounded by

695-543: A wormhole . Wormholes were appealing to writers due to their relative theoretical plausibility as a means of faster-than-light travel, and they were further popularized by speculative works of non-fiction such as Adrian Berry 's 1977 book The Iron Sun: Crossing the Universe Through Black Holes . Black holes and associated wormholes thus quickly became commonplace in fiction; according to science fiction scholar Brian Stableford , writing in

834-430: A "roller coaster ride". The character Major Charles Kawalsky describes Stargate travel as worse than "pulling out of a simulated bombing run in an F-16 at eight-plus g ", with Major Louis Ferretti adding that on the other side one is "frozen stiff like having just been through a blizzard naked". In later episodes the experience is no different from stepping through a door, explained as a result of refinements made to

973-554: A Male in a Dramatic Series for Stargate SG-1 in 2004, and Best Lead Performance by a Male in a Feature Length Drama for Stargate: Continuum in 2009. Born on July 8, 1965, Daniel Jackson is the only living child of Melburn and Claire Jackson, archaeologists who were crushed to death while supervising the placement of a piece of Egyptian art in the Metropolitan Museum of Art . Daniel's maternal grandfather and only living relative, Nick Ballard (played by Jan Rubeš ),

1112-460: A black hole created to neutralize a supernova threat has the side-effect of transporting two nearby spaceships into the past, where they end up altering the course of history . In Bolivian science fiction writer Giovanna Rivero 's 2012 novel Helena 2022: La vera crónica de un naufragio en el tiempo , a spaceship ends up in 1630s Italy as a result of an accidental encounter with a black hole. Black holes need not necessarily be stellar-mass ;

1251-572: A black hole that is sentient as a result of electromagnetic interactions in its accretion disk seeks to devour the Solar System. Daniel Jackson (Stargate) In the 1994 film, Dr. Jackson is an archaeologist who is a part of the first team to go through the Stargate on a reconnaissance mission, led by Colonel Jack O'Neil . He then becomes one of the main characters of the subsequent television series Stargate SG-1 , where he, Jack O'Neill , Samantha Carter and Teal'c make up SG-1,

1390-432: A body in a formal funeral service – the body was placed on a pyre in front of the gate, which was then activated. 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 beyond which

1529-597: A cameo appearance in the pilot of Stargate Atlantis , " Rising ", where he assists Rodney McKay and Elizabeth Weir on the Antarctic Outpost, unearthed in SG-1 's season 7 finale, " Lost City ". Here, he helps them to persuade Jack O'Neill to green-light the Atlantis expedition. Furthermore, he makes an appearance in the season 5 episodes " First Contact " and " The Lost Tribe " where he visits Atlantis to study

1668-483: A combination of six or more non-repeating symbols appearing on the dialing stargate. By "dialing" these symbols in the correct order, the traveler selects a three-dimensional destination. 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 : [REDACTED] [REDACTED] [REDACTED] [REDACTED] [REDACTED] [REDACTED] (corresponding to

1807-473: A common feature of modern space opera . Recurring themes in stories depicting micro black holes include spaceship propulsion , threatening or causing the destruction of the Earth, and serving as a source of gravity in outer-space settlements . [V]irtually the whole of gravitational physics can be understood using Newtonian theory . As far as real-world astrophysics goes, the most important exception to this

1946-478: A computer self-destructs by intentionally entering a black hole. In Mildred Downey Broxon 's 1978 short story " Singularity ", scientists study a civilization on a planet that will shortly be destroyed by an approaching black hole. John Varley 's 1978 short story " The Black Hole Passes " depicts an outpost in the Oort cloud being imperilled by a small black hole. In Stephen Baxter 's 1993 short story " Pilot ",

2085-409: A destination, by assigning them to each of the chevrons in sequence. These "addresses" are selected by turning the ring until the next symbol in the address is correctly aligned, which associates it with the next chevron. The 8th chevron, if used, specifies a different galaxy; the first 6 chevrons identify points in space within that galaxy to triangulate a physical location; the 7th is a symbol unique to

2224-400: A doorway; momentum, for instance, is conserved at either end of the wormhole. Human travellers exit the stargate with a sense of the journey that has been traversed. This normally feels effortless, but if the stargate has been improperly operated or is not functioning correctly, can be an uncomfortable experience. Each location in the Stargate universe has its own unique "address", which is

2363-413: 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

2502-403: 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

2641-459: A love-hate relationship with Vala Mal Doran between seasons 8 and 10; it is established multiple times that their feelings for each other are far deeper than either of them care to admit. Vala's daughter, the Orici Adria , develops an attraction to Daniel while attempting to convert him to the path of Origin during season 10. On a personal level, Jackson is very close to his teammates on

2780-626: A low average density and could theoretically contain intact stars and planets within their event horizons. An enormous yet low-density black hole of this kind appears in Barry N. Malzberg 's 1975 novel Galaxies . In Benford's Galactic Center Saga , starting with the 1977 novel In the Ocean of Night , the vicinity of the supermassive black hole at the Galactic Center of the Milky Way

2919-403: A means to achieve faster-than-light travel. The proposed mechanism involves travelling through the singularity at the center of a black hole and emerging at some other, perhaps very distant, place in the universe. More exotically, the point of emergence is occasionally portrayed as another point in time—thus enabling time travel —or even an entirely different universe . To explain why

3058-428: A notable visual-effects studio. However, some effects, including the entire Ori battle sequence in the episode " Camelot ", were done "in-house". 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. Rather than being

3197-560: A part of the Stargate Program whose goal is to explore the galaxy and defend against alien threats. Jackson is part of SG-1 until his death at the end of the season 5 , when he is replaced by Jonas Quinn . Upon his death, Dr. Jackson ascends to a higher plane of existence among the Ancients . He makes occasional appearances in season 6 before retaking human form and rejoining SG-1 in the seventh season . Jackson appears in

3336-529: A part of the team and later saves his brother-in-law Skaara from the Goa'uld Klorel in season 3's " Pretense ". In season 3's " Maternal Instinct ", Daniel discovers the Harcesis child on another planet and leaves him under the care of Oma Desala , a being of great power and wisdom. SG-1 meets Shifu again as a much older boy in season 4's " Absolute Power ". In the penultimate season 5 episode " Meridian ", Daniel

3475-421: A position in space can be extrapolated. He is then shown the stargate itself, uses his new understanding to identify the 7th 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

3614-471: A radio episode of Space Patrol that aired October 25, 1952 (in which it was called a "cycloplex" or a "hole in space"), and Robert A. Heinlein 's Tunnel in the Sky (1955) and its " Ramsbotham jump ". In 2001: A Space Odyssey , Arthur C. Clarke uses the term "Star Gate" for the large monolith "sentinel" TMA-2, which is a classic stargate portal to another part of the universe. The basic stargate concept

3753-520: 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 . There are further Stargate props that 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

3892-487: 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 backlit 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. On occasion, the Stargate itself is also completely swapped out for a computer generated model, usually in cases where it

4031-824: A small black hole is depicted in Paul J. McAuley 's 1990 short story " How We Lost the Moon " and is suspected to have occurred in Neal Stephenson 's 2015 novel Seveneves . Small black holes are used as a way to provide an artificial gravity of sorts by placing them inside inhabited structures or settled asteroids in Sheffield's 1989 novel Proteus Unbound , Reynolds's 2008 novel House of Suns , and Iain M. Banks 's 2010 novel Surface Detail . The titular material in Wil McCarthy 's 2000 novel The Collapsium

4170-582: A small black hole is used as a weapon against a rebellious planet. Earth is endangered by miniature black holes in Gregory Benford 's 1985 novel Artifact , Thomas Thurston Thomas 's 1986 novel The Doomsday Effect , and Brin's 1990 novel Earth , and the planet's destruction in this way forms part of the backstory in Dan Simmons 's 1989 novel Hyperion , while the Moon 's destruction by

4309-430: A so-called white hole , and as such acts as a gateway to another point in space which might be very distant from the point of entry. More exotically, the point of emergence is occasionally portrayed as another point in time—thus enabling time travel —or even an entirely different universe . More fanciful depictions of black holes that do not correspond to their known or predicted properties also appear. As nothing inside

4448-496: A spaceship extracts energy from a rotating black hole's ergosphere to widen its event horizon and cause a pursuer to fall into it. Black holes also appear as obstacles in the 2007 video game Super Mario Galaxy . Black holes have been depicted with varying degrees of accuracy to the scientific understanding of them. Because what lies beyond the event horizon is unknown and by definition unobservable from outside, authors have been free to employ artistic license when depicting

4587-412: 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, as such wormholes would most likely be created by excessive gravity (e.g., from a black hole), which would destroy any potential traveler. The Stargate film begins in 1928, when the alien device

4726-463: A straight line course to the destination. With the stargates of the Milky Way, with 38 address symbols and one point of origin, there are 1,987,690,320 possible six symbol co-ordinates (leading to 38!/(38-6)!/8/6=41,410,215 addresses as the six symbol addresses are composed of three tuples that can be permuted in 6 ways and the two symbols within each tuple are invariant for 8 more permutations.). With

4865-458: 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 in the fight against the Goa'uld. The primary team is called SG-1 , and the series follows their adventures. For a long time, it was thought that

5004-406: A type of "area code". Such connections, in comparison to seven symbol codes, require substantially more energy to complete a functional wormhole – much more than any standard dialing method can provide. In the first instance, opening an intergalactic wormhole is shown to exceed the total power generation capacity of the SGC at the time. O'Neill fashioned an additional power source using spare parts and

5143-405: A young woman in " The Broca Divide " while regressed to a primitive stage of Homo sapiens , is sexually assaulted by Hathor in " Hathor ", and is drugged and held prisoner to be the consort of a young woman named Shyla, the daughter of the planet's ruler, in " Need ". After Sha're's death, Daniel occasionally pursues other relationships: he is briefly drawn to Ke'ra (who turns out to be Linea ,

5282-573: Is also killed in a Goa'uld invasion in the Stargate Command, replaced by an alternate Daniel in "Stargate SG-1: The Gift of the Gods" from a doppelganger reality. In Stargate: Continuum Daniel is feared dead when he asks Carter and Mitchell to leave him behind while they search for help in the Arctic, only to be rescued by Col. O'Neill . Jackson is again killed by a Jaffa staff weapon near

5421-506: Is an arrogant, overbearing, insufferable ass, and can barely hide his dislike for his Atlantis counterpart. McKay's feeling is mutual, and they engaged in a verbal sparring match throughout their time together, but they at least have a mutual respect for each other's accomplishments. In the movie Stargate , Daniel Jackson, PhD , is presented as having several professional credentials including archaeologist , historian , and linguist . Jackson utilizes his skills in all three fields throughout

5560-555: Is an attractive destination for spacefaring civilizations due to the high concentration of stars that can serve as sources of energy in the region; a similar use is found for a regular-sized black hole in Benford's 1986 short story " As Big as the Ritz ", where its accretion disk provides ample solar energy for a space habitat. McAuley's 1991 novel Eternal Light involves a journey to the central supermassive black hole to investigate

5699-458: 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.

5838-438: Is depicted). The DVD commentary for Stargate SG-1 explains that these effects are produced by reflecting light off large sheets of vibrating Mylar . 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

In the season 9 opener " Avalon ", Vala seeks out Daniel at Stargate Command (SGC) and prevents him from going to Atlantis . The discovery of an Ancient communication device transports their minds to a village in a distant galaxy where they make contact with the Ori . Vala and Daniel can return to Earth safely, but unintentionally bring

6116-517: Is exposed to a lethal dose of radiation while attempting to fix a naquadria reactor on the planet Langara in the Nation State known as Kelowna. The Ancient, Oma Desala, guides Daniel to ascend to a higher plane of existence. The Kelownan scientist Jonas Quinn takes Daniel's place on SG-1 during season 6, although the rest of the team find it hard to get over Daniel's absence. Ascended Daniel visits O'Neill and Teal'c during times of crisis, but

6255-523: Is first discovered and unearthed at Giza , with a young Catherine Langford watching as her father Paul, the archaeologist who found it, directs its unearthing. Stargate SG-1 has since revealed more of the backstory of the Earth Stargate. The American ship Achilles brought the gate to America in 1939 to prevent it from falling into the hands of the Nazis . The United States Air Force then stored

6394-461: Is made up of a lattice of micro black holes and makes teleportation possible. At the opposite end of the spectrum, black holes can have masses comparable to that of an entire galaxy . Supermassive black holes , with masses that can be in excess of billions of times the mass of the Sun , are thought to exist in the center of most galaxies . Sufficiently large and massive black holes would have

6533-404: Is present. Rather, explorers from Destiny are required to bring an Ancient remote control that can command the gate to dial an address in addition to other functions, presenting them with a list of accessible Stargates. Within the Stargate fictional universe , stargates are hyper-advanced large rings that allow interplanetary and intergalactic travel. Objects can travel only from the origin to

6672-532: Is presumed dead after SG-1 is brainwashed to believe this in Season 1's " Fire and Water ". Daniel also is killed by Teal'c several times in a virtual reality system in Season 8's " Avatar ". Other deaths generally involve Daniel's teammates: they die together in " The Nox " (where they get resurrected by the Nox) and in the alternate future of " 2010 "; their robot versions are killed in " Double Jeopardy ", Daniel being

6811-611: Is proven correct about his claims that the Egyptian pyramids are much older than anyone believes, and even finds out they are of extraterrestrial design. As Lynn Meskell observed of the film Stargate : “Egypt represents everything Other, everything we cannot fathom or explain, all things ritualized, sacrificed and sexual’ and summed up in the film as the queered, extraterrestrial Ra, like Egypt identified as inexplicable, unnatural and evil...”(1998a:73). The show's staff and writers occasionally make jokes about Daniel's frequent "deaths" on

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. The journey takes a few seconds, even for the greatest distances. Objects passing between stargates behave as if they pass through

He dies of radiation poisoning in season 5's " Meridian " and Ascends to a higher plane until he reappears in Season 7's " Fallen (part 1) ". He is killed by RepliCarter at the very end of " Reckoning " and is seen at a midway point between Ascension and mortality before finally retaking human form in " Threads ". Daniel

7228-418: Is so strong that nothing—including light—can escape them, have been depicted in fiction since at least the pulp era of science fiction , before the term black hole was coined. A common portrayal at the time was of black holes as hazards to spacefarers, a motif that has also recurred in later works. The concept of black holes became popular in science and fiction alike in the 1960s. Authors quickly seized upon

7367-406: Is that it has at least two devices in distant positions, and 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, and there has been contention as to whether they plagiarized

7506-466: Is the existence of black holes. It's probably no coincidence that black holes also happen to be by far the most popular astrophysical phenomena found in science fiction . Andrew May, How Space Physics Really Works: Lessons from Well-Constructed Science Fiction The general concept of black holes , objects whose gravity is so strong that nothing—including light—can escape them, was first proposed by John Michell in 1783 and developed further in

7645-573: Is the only DHD in the Pegasus Galaxy capable of dialing Earth. A similar DHD is also used on Puddle Jumpers, where the set of used glyphs corresponds to the galaxy of the Puddle Jumper. The Wraith also travel through Stargates in small spacecraft called darts and have some means of remote-dialing them in a manner similar to Ancient ships. The show makes it clear that every Stargate originally had its own DHD, located directly in front of

7784-471: Is to confirm the presence of a DHD. In the absence of a DHD, a user must select the address by manually rotating the inner ring of the Stargate, and use an external power source, as the ring will not rotate unless it is energised. Pegasus Galaxy Stargates do not have a movable ring, so manually dialing these is impossible. Travelers can also emulate a DHD through a dialing computer as present at Stargate Command . Remote dialers have been used by several races like

7923-536: Is transported through a wormhole in Roger MacBride Allen 's 1990 novel The Ring of Charon . Travel between universes is depicted in Pohl and Jack Williamson 's 1991 novel The Singers of Time , the concept having earlier made a more fanciful appearance in the 1975 film The Giant Spider Invasion , where the spiders of the title arrive at Earth through a black hole. In the 2009 film Star Trek ,

8062-516: Is unknown if any other Stargates are reachable with a nine-symbol address, or if this is a feature unique to the Stargates on Destiny and Earth. Like eight-symbol addresses, the dialing of this address requires a significant amount of power, such that the scientists on Icarus Base had to tap into the planet's naqahdriah core. With the Stargates of the Milky Way, with 38 address symbols, there are 1,971,788,797,440 possible eight-symbol destinations. With

Clarke 's 1975 novel Imperial Earth , Charles Sheffield 's 1978 short story " Killing Vector ", and the 1997 film Event Horizon . Artificial black holes that are created unintentionally at nuclear facilities appear in Michael McCollum 's 1979 short story " Scoop " and Martin Caidin 's 1980 novel Star Bright . In David Langford 's 1982 novel The Space Eater ,

In the series, the fictional planet Abydos could be dialed because it is relatively close to Earth, although in the film, Abydos was located in the fictional Kaliam Galaxy. It

10425-508: 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 on 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

10564-609: The Ori threat to the Milky Way. After Vala is accidentally transported to the Ori galaxy in " Beachhead ", Daniel reunites with Vala aboard one of the invading Ori ships in the season 10 opener " Flesh and Blood ." After their escape, Daniel speaks up in support of Vala's request to join the SGC. With the ancient Merlin 's knowledge, Daniel builds the Sangraal in " The Quest ". Vala's rapidly matured daughter Adria captures Daniel and turns him into an Ori Prior in " The Shroud " to convert

10703-495: The SG-1 team in hopes of rescuing them. Daniel is briefly reunited with Sha're, who had been made host to Apophis' queen Amonet, in season 2's " Secrets ", when she temporarily controls her body while pregnant with the Harcesis child Shifu . Shortly after Teal'c kills Sha're in season 3's " Forever in a Day ", Sha're gives Daniel information to find her child, reconfirms her love for him and asks him to forgive Teal'c. Daniel remains

10842-481: The Stargate as a religious relic, often as a source of long-forgotten fear and evil. Direct-to-video films Stargate: The Ark of Truth (2008) and Stargate: Continuum (also 2008) expand upon the Stargate lore. 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

10981-400: The Stargates of the Pegasus or Destiny, with 35 address symbols, there are only 948,964,262,400 possible eight symbol destinations. Provided the ninth symbol is your point of origin. If the ninth symbol can also be added to the destination, even 59,153,663,923,200 combinations with a Milky Way stargate or 25,622,035,084,800 combinations with a Pegasus or Destiny Stargate are possible. There are

11120-508: The Tau'ri to the path of Origin, but Daniel returns to his normal self at the end of the episode. In " Unending ", the last episode of the series, SG-1 gets stuck in a time dilation field aboard the Earth ship Odyssey , and a romance between Vala and Daniel comes to fruition. Before the time dilation field is reversed after fifty years, erasing all linked memories in the process, Daniel and Vala express their feelings for each other. Jackson makes

11259-469: The ancient scientist Janus . Whilst there he and McKay are captured by a rogue branch of Asgard , who wish to use them to activate the "Attero Device" to neutralize the Wraith threat in the galaxy but with the unforeseen consequence of destroying the Stargates which would explode, killing tens of thousands of innocent people. In the time following the conclusion of Stargate Atlantis, Jackson still works for

11398-567: The back of the Gate, on the TV series, this effect was completely created in CG by the Canadian visual effects company Rainmaker . At the beginning of Season 9, the original movie wormhole sequence was substituted by a new sequence similar to the one already used on Stargate Atlantis but tinted bright blue (whereas in Atlantis it is green). Stargate Universe uses a darker shade of blue. Throughout

11537-402: 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

11676-488: The black holes avant la lettre as hazards to spacefarers. Later works that nevertheless predate the adoption of the current terminology include Fred Saberhagen 's 1965 short story " Masque of the Red Shift " with its "hypermass" and the 1967 Star Trek episode " Tomorrow Is Yesterday " with its "black star". Once black holes gained mainstream popularity, many of the early works featuring black holes focused on

11815-399: 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. 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

11954-433: The concept of gravitational time dilation , whereby time passes more slowly closer to a black hole due to the effects of general relativity. One consequence of this is that the process of crossing the event horizon —the distance away from the black hole where the escape velocity exceeds the speed of light —appears to an outside observer to take an infinite amount of time. In Poul Anderson 's 1968 short story " Kyrie ",

12093-457: The concept of the Stargate and wormhole travel. In the events of the third television series, Stargate Universe , a third generation of stargates is discovered, which allegedly predates the model originally discovered in the Milky Way galaxy. This model, discovered as a result of a three-month expedition to unlock the stargate's ninth and final chevron, was first encountered on board the ancient research vessel Destiny , which has been traversing

12232-438: 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 coordinates, creating three intersecting lines, the destination. The Stargate uses the seventh symbol as the point of origin allowing one to plot

12371-553: The decisive factor is whether sufficient mass is contained within a small enough space—the Schwarzschild radius . The principal mechanism of black hole formation is the gravitational collapse of a massive star , but other origins have been hypothesized, including so-called primordial black holes forming shortly after the Big Bang . Primordial black holes could theoretically be of virtually any conceivable size, though

12510-469: 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 that lasts roughly two 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 become affected by awe . Any matter that comes into contact with

12649-507: The destination, while certain electromagnetic waves can travel either way (for instance, visible light does not pass through at all, but radio transmissions pass in both directions). A stargate's destination is not fixed; any stargate can connect to any other stargate in the network. Stargates have an inner ring akin to a rotary dial inscribed with a number of symbols, and nine prominent points ("chevrons") spaced equally around their circumference. Between 7 and 9 symbols are combined to identify

12788-407: The device in various locations —including Washington, DC—before installing it at its location of the film and series. The Stargate was studied in the 1940s as a potential weapon and was later mothballed. As the Stargate film quickly skips to the "present day" (1994), unsuccessful archaeologist Daniel Jackson is giving a lecture about his outlandish theories that the pharaoh Khufu did not build

12927-546: The device, named the Stargate , function. Jackson then travels with a team, led by Jack O'Neill , through the Stargate, and they discover that it leads to the planet Abydos . Daniel meets, falls in love with, and marries a native woman, Sha'uri (named Sha're in the TV series Stargate SG-1 ). After winning the battle to free the Abydonians from the System Lord Ra , Daniel decides not to return to Earth with

13066-399: The dialing computer at the SGC . Under normal circumstances, a wormhole can only be maintained for slightly more than 38 minutes. Extending the wormhole duration beyond that requires tremendous amounts of power, such as that provided by a nearby black hole . While the "kawoosh" effect in the movie was created by filming the actual swirl of water in a glass tube, and looked like a vortex on

13205-621: 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. In order to allow for dialing back to Earth from other locations (without altering the dialing system), it was later stated that the DHD ("Dial-Home Device") normally attached to each stargate automatically updates for stellar drift; Earth's stargate lacks its DHD, requiring other accommodation. The alien race encountered in

13344-529: The end before Mitchell uses Ba'al's time-travel device to prevent Ba'al invading and conquering Earth. James Spader was intrigued by the script because he found it "awful". Mostly because of his manual-labourist view of acting, he accepted the role as a regular job that earned him some money. Michael Shanks was chosen because he did "the perfect imitation of James Spader ", according to Brad Wright . Showtime 's announcement to not renew Stargate SG-1 after season 5 coincided with Shanks' decision to leave

13483-430: The entire ring (as opposed to an inner track, like Milky Way-era gates) rotates clockwise and counterclockwise in an alternating pattern until the final chevron is locked and a wormhole is established. Finally, the event horizon of the wormhole also appears a slightly more silver color than later generations. Possibly due to the nature of how these stargates were deposited on hundreds of thousands of planets, no planetary DHD

13622-458: The event horizon before entering completely, as the Stargate would automatically reintegrate the traveler. Passage through a Stargate's wormhole is depicted as a visual effect of shooting through a tunnel in space. The average travel time between Stargates is 3.2 seconds. In the movie and early SG-1 episodes, travelers exit from the Stargate covered in frost and at high speed (often being knocked from their feet), feeling as though they have been on

13761-495: The film as it becomes evident that he specializes in Egyptology . Jackson, as an archaeologist, becomes the stereotypical academic – extremely smart, nerdy, socially awkward, and quirky. As a character, which further exemplifies this stereotype, Daniel represents an antithesis to the military stereotype of shoot first, ask questions later. Jackson is frequently depicted as approaching other cultures; past, present, and future, in

13900-461: The first to die; and a Goa'uld -possessed alternate timeline version of Daniel is shot by Teal'c in " Moebius ", while in another timeline in the same episode, all of SG-1 are killed except Daniel. In the series first instance of an alternate timeline, the Daniel from that timeline is also presumed dead as his last known location is Egypt which is shown to have been attacked by the Goa'uld . Daniel

14039-733: The framework of Albert Einstein 's theory of general relativity by Karl Schwarzschild in 1916. Serious scientific attention remained relatively limited until the 1960s, the same decade the term black hole was coined, though objects with the overall characteristics of black holes had made appearances in fiction decades earlier during the pulp era of science fiction. Examples of this include E. E. Smith 's 1928 novel The Skylark of Space with its "black sun", Frank K. Kelly  [ Wikidata ] 's 1935 short story " Starship Invincible " with its "Hole in Space", and Nat Schachner 's 1938 short story " Negative Space "—all of which portray

14178-541: The gate and facing it. 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 Mobile Analytic Laboratory Probe (M.A.L.P.), an unmanned ground vehicle that precedes an SG team ,

14317-475: The gate can also be dialled by manually forcing the ring to move into each position. Once a valid address is dialed by the traveler, if a functioning counterpart device exists close enough to those coordinates, the stargate generates a stable wormhole between itself and its counterpart. The advanced technology of the stargate allows it to accept a wide range of power sources, which it can absorb by direct conduction if required. The power source in most situations

14456-451: 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". This puddle may then be entered (usually accompanied by a watery squishing 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

14595-424: The idea from a previous script submission from a student of Egyptology named Omar Zuhdi, who submitted a screenplay to them about ten years before the movie was made. Zuhdi pursued legal action regarding this, and the case was eventually settled out of court. Much of the inspiration for the functioning of the device is drawn heavily from theoretical astrophysics , particularly that of black holes and wormholes ,

14734-404: 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 visual effects for Stargate SG-1 and Stargate Atlantis are predominantly produced by Rainmaker Digital Effects ,

14873-531: The immense gravitational field of the black hole does not crush the travellers and their vessels, the special theorized properties of rotating black holes are sometimes invoked by authors; astrophysicists Steven D. Bloom and Andrew May argue that the strong tidal forces would nevertheless invariably be fatal, May pointing specifically to spaghettification . According to The Encyclopedia of Science Fiction , early stories employing black holes for this purpose tended to use alternative terminology to obfuscate

15012-778: The inside of a black hole is used as a prison, a role it also serves in Alan Moore and Dave Gibbons 's 1985 Superman comic book story " For the Man Who Has Everything ". Alien lifeforms inhabit the interior of a black hole in McCarthy's 1995 novel Flies from the Amber . Expeditions into black holes to explore the interior are depicted in Geoffrey A. Landis 's 1998 short story " Approaching Perimelasma " and Egan's 1998 short story " The Planck Dive ". In much

15151-451: The interiors of black holes. The 1979 film The Black Hole , noted for its inaccurate portrayal of the known properties of black holes discernible from without, depicts the inside as an otherworldly place bearing the hallmarks of Christian conceptions of the afterlife . In Benford's 1990 novel Beyond the Fall of Night , a sequel to Clarke's 1948 novel Against the Fall of Night ,

15290-446: The laws of ascended beings forbid him to directly interfere, with his visits simply consisting of providing moral support to his old teammates as they face torturous experiences on their own. In the season 6 finale " Full Circle ", ascended Daniel seeks to aid SG-1 in defeating the plans of Anubis . Before Daniel can destroy Anubis, he is whisked away, but Oma helps Daniel by ascending the entire population of Abydos before Anubis destroys

15429-508: The liquid naquadah power core of a staff weapon using the same enhanced knowledge that had allowed him to determine this address in the first place, but this new power source only functioned twice and required repair work to operate the second time. A fully charged Zero Point Module (ZPM) can provide enough power for regular travel between galaxies. The 8th chevron is a key element in the Stargate Atlantis series, allowing travel to

15568-445: The ninth chevron never having been explored in the previous series. The nine-symbol addresses act as codes to dial specific Stargates, with the only two known nine-symbol addresses used to dial from the Milky Way galaxy to Destiny , a massive Ancient vessel that was part of a project to explore the universe, with the project being abandoned when they started researching into ascension among other things, and from Destiny to Earth . It

15707-421: The order in which the addresses were dialed, and no guarantee can be made as to the accuracy of the recovered addresses. The Atlantis DHD is more similar to the Earth's dialing computer than an actual DHD, and looks more like a set of crystal panels. It can block out certain gate addresses. The Atlantis DHD also has an extra control-crystal allowing the dialing of an eighth chevron during the dialing sequence and

15846-520: The original SG-1, with each of them constantly depicted as willing to go to great lengths to protect each other, even with such moments as Teal'c's role in Sha're being taken by Apophis or Jack distancing himself from the others to go undercover and expose the NID's theft of alien artifacts. Jackson has an antagonistic relationship with Dr. Rodney McKay, as evidenced in season 5 of Stargate: Atlantis. He feels McKay

15985-507: 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 supporting human life, often in civilizations more primitive than Earth. The majority of these civilizations, descended from former Goa'uld slaves, treat

16124-414: The penultimate season 5 episode " Meridian ". For his portrayal of Daniel Jackson, Michael Shanks was nominated for a Leo Award in 2000 for "Best Performance by a Male in a Dramatic Series" in 2000 for the episode "Forever in a Day". After a 2004 Leo win in the category "Dramatic Series: Best Lead Performance by a Male" for " Lifeboat ", Shanks was nominated for a 2005 Leo Award in the same category for

16263-533: The planet. Daniel is discovered naked and without memory on the planet Vis Uban in the season 7 opener " Fallen ". Daniel rejoins SG-1 full-time one episode later, and Jonas returns to his people. Daniel spends much of season 7 trying to tap into his Ascended memories of his time of Ascension and to find the Lost City of the Ancients . This leads to the discovery of the Ancient Outpost at Antarctica in

16402-535: The process appearing to still be ongoing. Later sequels in Pohl's Heechee Saga , from the 1980 novel Beyond the Blue Event Horizon onward, portray time dilation being exploited by aliens who reside near a black hole to experience the passage of time more slowly than the rest of the universe; other aliens do likewise in David Brin 's 1984 short story " The Crystal Spheres " while waiting for

16541-403: The rest of the team and to instead live the rest of his life learning about the culture and history of Abydos, with its culture based on that of ancient Egypt. Jack O'Neill lies to his superiors, saying that Daniel Jackson is dead. In the television series Stargate SG-1 , Daniel's life changes when his wife and his brother-in-law are abducted and turned into hosts for the Goa'uld . Daniel joins

16680-457: 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. Each DHD only has 38 keys, 19 on each ring. According to Dr. Zelenka , dialing an address leaves a small imprint on the control crystals of the DHD, and about fifty addresses can be recovered from a DHD using the proper equipment. However, this gives no indication of

16819-416: The run of the television franchise, it cost $ 5,000 to show a person stepping through the event horizon, using visual effects. 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

16958-527: The same way as stars—and, to a lesser extent, planets—have been anthropomorphized as living and thinking beings, so have black holes. An intelligent, talking black hole appears in Varley's 1977 short story " Lollipop and the Tar Baby ". In Sheffield's Proteus Unbound , microscopic black holes are determined to contain intelligence through signals emanating from them. In Benford's 2000 novel Eater ,

17097-495: The season 7 finale " Lost City ", contributing to the spin-off Stargate Atlantis . In season 8's " Prometheus Unbound ", Daniel meets Vala Mal Doran , who seizes the Prometheus with him on board. Although Daniel evades her sexual advances and thwarts her plans, she escapes. After Daniel's death at the hands of RepliCarter in " Reckoning (Part 2) ", Oma Desala provides a path for Daniel to ascend in " Threads ", but Daniel

17236-415: The series until the finale at the end of the tenth season , and appears in both direct-to-DVD films that act as sequels to the series. He also appears in three episodes of Stargate Atlantis and four episodes of Stargate Universe . For his portrayal of Jackson, Shanks was nominated for three Saturn Awards for Best Actor on Television , and for five Leo Awards , winning two: Best Lead Performance by

17375-461: The show for concerns of being underutilized. Panicking fans started massive write-in fan campaigns to save the show and the character, partly conflating the two issues, but Sci-Fi Channel decided to continue the show and fill the void with a new character. Casting agents met Corin Nemec at the courtyard of MGM's Santa Monica offices by chance and offered him the role of Jonas Quinn , beginning with

17514-466: The show. In the season 7 episode " Heroes ", one of the SG teams examine some ancient ruins and a scientist says "Dr. Jackson is gonna die when he sees this!" to which another member (Col. David Dixon, played by Adam Baldwin ) responds "What, again?". Comparisons have also been made between Daniel and Kenny from the cartoon series South Park . Daniel's first death is by staff blast while he defends O'Neil; he

17653-526: The smallest ones would by now have evaporated into nothing due to the quantum mechanical effect known as Hawking radiation . The concept of micro black holes was first theorized in the 1970s, and quickly became popular in science fiction. In Larry Niven 's 1974 short story " The Hole Man ", a microscopic black hole is used as a murder weapon by exploiting the tidal effects at short range, and in Niven's 1975 short story " The Borderland of Sol ", one

17792-426: The specific gate, which identifies it as the point of origin; and the 9th is reserved for special destinations. The gates were originally constructed with complementary control panels nearby, inscribed with the same symbols as can be found on the ring. Pressing these symbols would supply power to the gate and cause the inner ring to spin automatically until the selected symbol is aligned and the chevron engaged. However

17931-402: The stargates of the Pegasus or Destiny, with 35 address symbols and one point of origin, there are only 1,168,675,200 possible six symbol coordinates. By identifying six constellations in space, a single sextangulation point can be interpolated that corresponds to the destination desired. As only a small portion of the possible combinations of Stargate symbols represent valid addresses, dialing

18070-571: The television series Stargate SG-1 , Stargate Infinity , Stargate Atlantis , Stargate Universe , and Stargate Origins . In these productions, the Stargate functions as a plot device , allowing the main characters to visit alien planets without the need for spaceships or any other type of technology. The device allows for near-instantaneous teleportation across both interstellar and extragalactic distances. Some early "portal" appearances in science fiction include A. E. van Vogt 's novella Secret Unattainable (July 1942, Astounding ),

18209-433: The traveler to be destroyed. Although in the first episode the Goa'uld who come through at the beginning appear to walk back through the event horizon after taking a hostage, in actuality they dialed out again using a hand-held device, as the whooshing sound is audible in the background. As matter is only transmitted through a Stargate once the whole object has passed the event horizon, a person or object could be retrieved from

18348-442: The underlying issues. Thus, Joe Haldeman 's 1974 fix-up novel The Forever War , where a network of black holes is used for interstellar warfare, calls them " collapsars ", while George R. R. Martin 's 1972 short story " The Second Kind of Loneliness " has a "nullspace vortex". Speculation that black holes might be connected to their hypothetical opposites, white holes , soon followed—the resulting arrangement being known as

18487-483: The universe for several million years uncrewed, and is several billion light years away from Earth. It is discovered that the Ancients constructed the vessel to be launched after a number of stargate seed ships were dispersed in the universe in order to follow in their path and stop at each planet at which a stargate was deposited. Destiny would then extract any relevant data from the planetary stargate in order to further complete research into an apparent signal embedded in

18626-666: The universe to be more filled with life, and in Alastair Reynolds 's 2000 novel Revelation Space , they do it to hide. In Bill Johnson 's 1982 short story " Meet Me at Apogee ", travel to various levels of time dilation is commercialized, used by people with incurable diseases among others. In the 2014 film Interstellar , a planet orbits a black hole so closely that it experiences extreme time dilation, with time passing approximately 60,000 times slower than on Earth. Black holes have also been portrayed as ways to travel through space. In particular, they often serve as

18765-433: The vortex is annihilated on a molecular level, as is dramatically demonstrated by a pair of smoking shoes in the episode " Prisoners ". In season 9's " Crusade ", the unstable vortex was onomatopoeidiacally referred to by Col. Carter as the "Kawoosh", emulating the sound of the initial vortex. This aspect has been used in some cases to dispose of highly hazardous materials. The vortex is also used on one occasion to dispose of

18904-456: The way to Icarus base, growing increasingly annoyed at the "in-flight safety tip" type recordings Jackson made. Jackson marries Sha're due to a misunderstanding on the first mission to Abydos and remains with her for a year on Abydos until she is taken as a host for Amonet (" Children of the Gods "). He remains committed to her until her death in " Forever in a Day ". Prior to this, Daniel's moments of (involuntary) infidelity include claiming

19043-560: Was a noted Dutch archaeologist and too busy to take the orphaned Jackson under his wing. Though placed in foster care, Daniel visited his grandfather in a mental institution until they had an argument over his failing career and Daniel left. Daniel became an archaeologist and linguist who speaks 23 earthly (plus several extraterrestrial) languages—he is shown speaking at least English , Russian , German , Spanish , Mandarin Chinese , Egyptian , Goa'uld , Ancient , and Unas . In

19182-461: Was initially believed that the Goa'uld created the Stargates, but this was proven false in "The Torment of Tantalus" when the SGC discovered that Earth had accidentally dialled an address in 1945 that was not on the Abydos cartouche. Following this revelation, a larger list of Stargate addresses is provided by Jack O'Neill in " The Fifth Race " from knowledge downloaded into his mind by a repository of

19321-581: Was visited in the film and was at the time erroneously believed to be located in the Kaliam Galaxy, billions of light years away on the other side of the known universe. 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 of the stellar drift accumulated over millions of years, other addresses were impossible to dial until Samantha Carter reworked
