All you ever wanted to know about the 9th chevron

[Greenfire32]

Maybe I am missing something here but how did we know there was a ninth chevron back in 2004? why can't there be 10 chevrons?

I'll go easy on you because you're a probie. Pop in Stargate the movie and count the chevrons. There's 9 of them.

Rush theorized that the ninth chevron was used to lock onto moving targets though.

And where did you hear that?

The Ninth Chevron idea of it tracking doesn't make sense given stargates don't jump connections at least not safely. if the Gate was to move it would leave a location causing it to cut out. Because it would have left the location it was originally.

Would it not make more sense for it to be a further extension given the sheer number of planets, moons, dwarf planets, asteroids. So rather it's to dial between the clusters.

This would make sense given MilkyWay and Pegasus are in the Local group. Thus only an 8 digit address is needed.

123456-Point of origin-Galaxy(In this galaxies same group)-Cluster(To jump between groups)

I'm not saying that it's not possible for them to not assign a gate location for some reason (maybe they didn't chart a cluster for them to assign it, maybe they keep one aside for use later maybe like 555 is used in US films) and assign that to a special program in all the DhDs for certain ships. So that it scans through the network until it gets a gate that is identified as Destiny gate. Then opens the gate between here a destiny.

Maybe to dial 9 chevrons it requires this special planet energy. Possibly even the Subspace ZPM thingy (The One that Mckay couldn't make work, Blew up a solar system trying) Or a different power source.

I just don't think it makes much sense to use the 9th chevron given the sheer number of gates. if it's used to track a moving gate.

The Ninth Chevron idea of it tracking doesn't make sense given stargates don't jump connections at least not safely. if the Gate was to move it would leave a location causing it to cut out. Because it would have left the location it was originally.

Mckay said in Adrift (4x01) that to use a Stargate it must remain in a small area space, when anyone dials Destiny she drops to sub-lights, maybe even stops completely to allow the transfer to take place. The ninth chevron is just a range and location finder for the Destiny gate, as Destiny doesnt move very far when her stargate is being used for either incoming or outgoing wormholes, she doesnt leave the small area of space which the current dial-in address correlates to.

Or the ninth chevron is a signal to Destiny to drop out of FTL and remain stationary to facilitate transfer.

Every gate is moving. If it is on a planet then it moves as the planet spins on its axis and while it orbits the star.

[JoseP927]

But compared to FTL, they are moving very slowly. Even so, the DHDs have to update the coordinates every several hundred years or so (Avenger 2.0). The ninth cheveron could be thought of a command to do an instant correlative update, or more accurately, an integral of a correlative update (it updates ∆position/∆t).

Okay, we all know the basic deal: 1-6 are for a location, 7th is a Point of Origin.

So Normal Address:
XXXXXXY
X-Location
Y-Point of Origin

Okay, now from the 5th race and Atlantis we have 8-Chevron address:
XXXXXXAY
X-Location
A-"Area Code" (Galaxy Address)
Y-Point of Origin

Alright, now we have the 9th Chevron which has yet to be used, now here is an idea i read and i kinda like it: an Extension. This would come into play when there is more than one gate in a given area. Now i know you already think: well, duh, that cant be true because we had two gates, and we never needed to use the 9th chevron. Well right you are, because if the Ninth isnt used it goes the to the Primary gate, which so happened to be ours.

Okay, so here is how i think a 9 Gate Address would go.
XXXXXXABY
X-Location
A-"Area Code" (Galaxy Address)
B-"Extension" (Gate Selector)
Y-Point of Origin.

Now if you wanted to go to a planet with more than one gate in the same galaxy you just ignore the area code, which would just mean that it activates a different chevron.

In other words, each chevron has a duty, even in a 8 or 9 glyph address

1-6 are ALWAYS destination glyphs
7 is ALWAYS point of origin
8 is ALWAYS galactic addresses
9 is ALWAYS a gate selector

all thats different is the order the chevrons activate.
for a normal connection its: 1-2-3-4-5-6-7
for a out of galaxy its 1-2-3-4-5-6-8-7
for an extension its 1-2-3-4-5-6-8-9-7 if out of galaxy
for an extension in galaxy is 1-2-3-4-5-6-9-7

okay, what do you think?

the thing is with a 7 you have 6 points which makes the center where the point are crossed that is the destintion,7th being begaining point,so in order to dail a different galaxy a MW gate would have to have constlations of the stars in pegasuse,right,which means you would need 6 symbols that you cannot use for anything other then dailing pegause,so being that destiny is so far out and no one knows where it is,how would you get the markings to dail it,you have to have 6 points in space to get a single point,how would a MW gate have sybols that have not been seen yet,does not make sence at all its another writers error

[bra'tec]

I never thought of it like that

The theory is different. However it seems flawed and unlikely. Knowing that using the 8th Chevron takes a whole load of energy, we can establish that the 9th chevron would take up so much more energy. But it would seem pointless then to waste a ZPM just to get to a second gate on some planet! Maybe it would have strategic advantages... but still.. Why?

Alternate Universes are cooler and more likely.

The power required for the 8 chevron address is so great due to the distance traveled, (E.G. earth to othala, earth to atlantis, supergate to ori galaxy), and the same for the 9th chevron. However, the ninth chevron address is not an address per se, but a type of code. In the series opener, using the point of origin as the final chevron yielded no result, and only using earths symbol could get the gate open. This suggests that (presuming Destiny is the only ship of its kind) there is only two 9 chevron addresses (Destiny, and Earth). The ancients had built transporters all over Atlantis and were the originators of the ring transporters and the builders of the "puddle-jumper" ships, which means that the need for travelling to get to the other side of a planet would be a non-issue. That said, i suppose it wouldnt be impossible to travel from one gate to another on the same planet, especially with only one DHD involved, but it would take intricate calculations and it would most likely only be a seven chevron address, maybe even six since both gates are on the point of origin planet.
