| Stargate | ||
A large circular ring, roughly 20 feet in diameter, the Stargate is made of the quartzite metal element called Naquadah. There is a vast network of them throughout the Galaxy.The Stargate is made of a metal not found on earth (Naquada). The metal is the only known element that absorbs (and energizes with) neutrinos. Somehow, when energized with neutrinos, the gate forms a stable artificial worm-hole with another gate. It will not react with any other substance -- radiation, particle bombardment, fire, pressure, etc. So with a valid glyph sequence encoded, and given a neutrino energy burst, the gate opens an artificial worm-hole to a remote Stargate. The Stargate can then instantaneously transport an object from one point in space to another. A wormhole is created between any two Stargates when one Stargate dials the address of another Stargate. All together, the Stargate contains 39 symbols, one of which represents a point of origin unique to that Stargate, and has 9 chevrons (of which, so far, only a maximum of 8 have been used) that are used to lock on to Stargate symbols and dial another Stargate. This sequence of symbols corresponds to vectors in three dimensional space where the target Stargate is located. A Stargate uses 6 of 38 symbols, representing star constellations, to locate another Stargate and then uses a final 7th symbol, unique to each Stargate, as its point of origin. So when dialing a destination on the gate, there are actually 7 chevrons used, 6 for the destination and the 7th is the point of origin. Although there are 9 chevrons in total no more than 8 have been used, when they went from Earth to the Pegasus galaxy. The 8th chevron was originally able to be used with the power booster that O'Neill was able to build with the knowledge of the Ancients in his brain (Stargate SG-1), and now using the ZPM, "The extra chevron adds a new distance calculation to the existing points, like a different area code, enabling them to dial a different galaxy. The purpose or function of the ninth chevron is still unknown. THE ATLANTIS STARGATE The chevrons are blue on the Atlantis gate, and, of course, the symbols themselves are different in this galaxy. Instead of physically spinning, the inner track spins in a pattern of light. The brightly-lit symbols also rotate around much faster than Earth's gate. The team accesses the gate's control systems -- more like a computer than a D.H.D. -- along with a new library of addresses, most of which are presumably for the Pegasus galaxy's gate network. After dialing another world, the tried-and-true system of M.A.L.P. probes and G.D.O. transmitters are still used. The Stargate at Atlantis is the only one they know of from the Pegasus galaxy that can dial Earth. At the touch of a button, the gate may be protected by an iris-like energy shield that the Ancient's revised, blocking matter from rematerializing. Things picked up from the show:- A Stargate can only send things through the wormhole in one piece. "The Stargate transports matter in discrete units," notes scientist Peter Grodin. "The outgoing Stargate won't transmit the matter stream until the demolecularization is complete." So "the front half of [an object] cannot rematerialize until the whole [object] has crossed into the event horizon. The Stargate is essentially 'waiting' for the contiguous components ... to enter completely before it can transport them. The Atlantis Stargate has blue chevrons not red like the Earth one. And it has only constellation panels instead of 39 . Text by zandr modified by Matej Dominik Voboril |
