I like how they are on another planet like it's a hiking trip. Lets dial this random place and go in a t-shirt

So I always assumed that the7 symbol addresses were 6 spatial coordinates (sc), plus the point-of-origin (po), while the eight were 6 sc + 1 po + a special distance modifier (sd), and the nine symbol address was just 6 sc + 1 po + 1 sd + something else. The idea that it is not that, but it is fundamentally something else, but rather reveals a qualitatively brand new aspect of the gates, an absolute address(!) is just so mind-blowing! The idea that any gate can be dialed absolutely just makes so much sense...

Man the Startgate franchise is so fascinating. I really hope the show will come back.

NICELY done Sir!!! This was well thought out and well described.. I'd buy you pint or two or three if we were in close proximity as you properly well deserve it!! WELL DONE INDEED!!!

good explanation, always thought that one gate dials to another.

I think I remember when Thor came to Earth to ask for help (that was the episode where he took Carter with him because he "needed someone dumber than he is", right?) Anyway, he had a little white stone that he used to dial back to Ida, without needing to use the SGC's dialing computer at all. Really impressive technology, not only a handheld dialer but also a wireless power source if it could connect that far. I've been thinking about relative power requirements, and I think Ida must be a lot closer than Pegasus (though possibly in the opposite direction, i.e. [Ida] - - - - - [Milky Way] - - - - - - - - - - - - - - - - - - - [Pegasus] or something like that) O'Neill's generator to connect MW to Ida ran off the liquid naqhadah cell from Teal'c's staff weapon (not very big, he only got 1 use out of it) A regular naquadah generator isn't enough to power the Ancient chair platform, for that they needed either a ZPM or a Mk 2 generator that lasted a few hours in The Siege. By the time the Atlantis expedition left, a number of years had passed since O'Neill built his generator. Scientists would have plenty of time to pick it apart and learn everything they could from it. In other words, the Mk 2 generator should be at least as powerful as the O'Neill generator. The Mk 2 generator was never even suggested as an alternative for dialing between MW and Pegasus. Even if it would take 10 of the things all linked together, that would still be a preferable alternative to hauling dozens of stargates around to build the gate bridge and midway station. The only power source they tried for this was a ZPM, black hole, or the alien fog on that planet that simulated "Earth" for everyone. In other words, it seems like the MW -> Pegasus connection is massively more expensive than the MW -> Ida one.

Due to the correlative update system mentioned in the show, to me the 7 and 8 symbol addresses were just DNS for the network used to look up the real gate address based on position.

My own theory about the ninth chevron is that it's a velocity variable telling the gate to search not just a specific region of space, but the entire universe for Destiny, and also serves as a signal telling Destiny to drop out of FTL and accept an incoming wormhole. As seen in the show, only a 9-chevron dial-in is able to force Destiny to drop out of FTL.

Logical. I don't recall watching that much of Destiny to see a return gate back to Earth. I do remember in the early show at least, only 7 locks on the stargate, unless the 2 additional locks were automatic. But when you get right down to it, the whole thing is like dialling a phone. except the number is in reverse order. traditionally in the UK we had 6-digit landlines (when I grew up, it used to be different before), then if you wanted to dial out of the area, you needed another 5-digit area code. Finally to call international number you needed the international code. So landlines became (Int code - area code - local number) Now in SG1, you have point of origin, so we can assume the system is a bit different order (i.e reversed) but we can also assume that it's a bit like a send call button. So discounting that send button, there are really only 6, 7 and 8-digit codes. Local galexy, area (diff galaxy), International. i.e. a roaming mobile spaceship somewhere in the universe. So considering the dial button, maybe it is in the same order we use? How pissed though would the Ancients be if some other alien species from another galaxy just happened to have built their own network, and maybe pissing about or got drunk ended up calling up the Ancient's network. not nessesarilly earth. but could have a few super advanced aliens hoping around our galaxy, looking for a way home to their galexy after they realised they screwed up. I could imagine that the Nox and the Tolen might be just a bit surprised someone is using their gates through their defences. Certainly the Tolen might or might not point them to earth as a people with experience in long range gate use. (assuming the Tolen know about Atlantis etc)

People also got shot out of gates during their early use in Season 1 and the original movie. This was explained as happening because the Earth gate did not have a DHD and thus wasn't updated for stellar drift, so the Earth gate had an offset connection to Abydos causing issues, basically Abydos was at the outer edge of the zone of space the gate assumed the Abydos gate would be in. This implies that gates can be connected even while they aren't entirely sure of the other gate's location in space and that the wormhole doesn't auto adjust to the actual location but even after connection confirmation is still just sent to a general area, further confirmed by damage to gates being able to redirect wormholes to nearby gates, basically the gates are built as "magnets" to wormholes and just opening a wormhole in their general area will cause a "lock". As a side note this also means that you cannot have multiple gates in close proximity with different addresses, IE on multiple planets in the same system and possibly a star system could even block its neighbors from having addressable gates if those neighbors were close enough to it. Overlapping addresses would cause havoc on the gate network if the 7 symbol addresses really do work as implied, so they must be separated and not overlapping. We know from Earth's use of Naquadriah hyperdrive technology that gravity interferes with subspace (drive failed going near a collapsing supermassive star), and the gates use similar areas of subspace to hyperdrive technology (known from SGA and the Attero device which disrupted hyperspace travel and gate travel at the same time.) Combine these facts and we can surmise that a massive object must be able to mess with gate travel. During Red Sun it is likely that the gate didn't want to connect because the path between the two gates was "offset" due to gravitational interference, the effect being the same as if a gate had experienced enough stellar drift to be just on the edge of the area of space it was supposed to be in. Carter messed with the Earth gate system to allow a "bad" connection, just like Earth had a bad connection to Abydos before they incorporated the new information from the Abydos Cartouche into their dialing program. One interesting thing about episodes like Red Sun is that they tell us that the Milky Way gates and their DHDs have overlapping functions. The gate itself has computational power and programming and does safety and sanity checks on what is going on, it is not just the DHD doing such stuff. Yet the DHD for some reason handles stellar drift calculation updates, dialing and some error handling (as seen in Fifth Race and 48 hours.) It strikes me as odd that the Ancients chose to not put all error handling and sanity checking into the gate itself and delegated some of it out to a remote device which may or may not always be there. It also seems that the Ancients realized this when they designed the Pegasus gates, given that they are designed to function in full without a DHD (as seen especially with their space gates and use of a lot of various temporary DHD types across that galaxy.) Still Pegasus gates can be "overridden" by their DHD given that the Atlantis dialing crystal can be incorporated into a DHD to enable 8 chevron dialing anywhere, maybe it's actually that the DHDs function as duplicates and extensions of the gate programming itself, allowing a complete override of the gate's own systems when a DHD is in place. After all, even "hard" rules like the 38 minute window on open wormholes is overridden several times on the show by Ancient devices, so its likely that with advanced enough understanding of the gate the SGC could bypass even that part of the gate's safety programming. I like the idea that all gates might have hidden 9 chevron addresses, but they wouldn't be viable for normal use due to the omni-directional connect signal being way too costly in energy for normal use. I just don't think it is likely to be the case though because such a 9 chevron address library would have to be built into every gate from its creation which leads to issues when we take into account non-Alterran gates or latter additions to the gate system. I think it is more likely that the Ancients created a few 9 symbol addresses for specific gates and left the majority to function normally. It also brings up the thought, what if Earth was still using the alpha gate when Destiny tried dialing the Earth 9 symbol address? Would they have connected to the beta gate instead since that was the original Ancient gate and not the latter Goa'uld placed one? If I had to guess there likely isn't much more than a handful of 9 chevron addresses in total, Earth, Destiny and possibly Atlantis and any other place of equal importance. Perhaps the Ancients included a small list of 9 symbol addresses in all gate base coding to allow for future use and some of them could even be entirely disused. Then again we are told that the only 9 chevron address that shows up so far in the Atlantis database is the Destiny one, so maybe there really isn't even more than that. All in all the ninth chevron seem to break all rules of the 7 and 8 symbol addresses, so we probably shouldn't use it to make any logical deductions about general gate functions.

A number of Pegasus space gates had visibly only 8 chevron positions.

We assume that stargates has interstellar stations to links with 100+ destinations of constellations. Milky way, Atlas, Antares, and neighboring Andromeda are sets more spaceports than other places.

Such good knowledge.

who else is amped about new stargate coming out!

The address does change, just over galactic timescales. As the planets and stars move over thousands of years, the addresses gradually shift. If the gate hasn't moved too much, you can still connect to your target, but imperfectly, resulting in a rough transit and things like coming out covered in ice. If the planet has moved too much, though, the address will simply fail to connect, or connect to another world that has moved to the old location (very rare). This is why stargate command couldn't immediately use the addresses from the Abydos Cartouche; they had to evolve the stellar potions forward in order to get the current addresses, as all those on it were so far out of alignment as to fail to connect. In fact, Abydos itself was barely still in alignment, and in a few years they probably wouldn't have been able to connect with the address they found on gate cover either. Extragalactic addresses technically had the same issue, but since they defaulted to a single gate in the target galaxy, so long as the entire galaxy hadn't moved out of alignment, the address could still lock onto the galaxy's default even if it had significantly moved within its own galaxy (moving the special crystal that identified the Atlantis gate or specialized programming could change this default for Pegasus; it's never stated if Othala was set as the default for Ida in a similar way, but it does make sense the ancients would set that world as the default). One possible reason the Pegasus gates moved away form the embossed symbols could have been to allow the symbols themselves to more readily change as constellations did (thinking in longer time frames as their civilization became older). It's also unclear if Destiny proto-gates work this way; it's possible each proto-gate has its own address and the controllers just read it off.

What I don't understand is why a symbol for the origin must be provided. I imagine when a planet is pinged, the origin symbol gets translated into a six symbol address, allowing the other end of the wormhole to open. What I don't understand is why that can't occur automatically. You are always going to have the origin symbol as the last one, right? Unless there's some hidden reason to not include an origin...

so... 7 symbols is a phone number without area code 8 symbols is a phone number with an area code 9 symbols is an IPV6 address

If 9 chevrons is a physical address, that makes the Atlantis gates strange having the least amount of glyphs when they are the newest version. They should have equal or greater than other gates.

If the 9 chevron addresses dial a specific gate, why does Destiny's address to Earth still work? Since the Earth gate is once again the gate from Giza, which as you mentioned was the 2nd Stargate placed on Earth?

I did notice something, bugging me, the ancients, Alterans i think, built the gates destiny etc, but wen they dialed the 9th chevron, they used the icon from the goauld gate, wen they should have used the one from the ancients gate.

So something like the Puddle Jumper dialer has a non-descript "point of origin button" that works to hit the unique symbol automatically?

Hate being that guy but I do say this mostly to be informative rather than correcting. A seven chevron address would be intragalactic (within a galaxy) or interstellar (between star systems) while an eight chevron address would be intergalactic (between galaxies). It's a common misunderstanding.

It is probable me just being THICK but i am still total lost but THANK YOU 4 TRYING

So does that mean that every Gate and DHD, on a Planet has a Different Symbol as Home? If so then the DHD is locked to the gate since there is no 2nd one anywhere?

point of origin means from where are you travelling

So, gate work like an IP adress or a phone number ?

All Stargates must have the same 39 symbols. Else some gates will be inaccessible without multiple hops and that is a stupid design that Ancients will never do. Like you have to go to Mongolia physically to dial Korea and go there. This means total gates in a galaxy is fixed to 1.9billion gates. Also it is super easy to find point of origin because it's the only unique symbol on gate and dhd. This also means any gate can go anywhere and work because you're getting to a spatial coord and not the gate per se. Imagine milky way in a box. Every gate has unique xyz coord. Which means only 3 symbols are actually enough and point of origin is not even required. The big red button could just be the p. O. O. Also it would be cool if you could see live view through the gate itself. Like looking through a swimming pool to the bottom. Bidirectional travel would also have been better use of 9th symbol (their version of upgraded system). Stellar drift is nonsense since these are digital systems. The coords won't change to diff symbols and gate address can't change so the concept of stellar drift makes no sense Anyways despite its flaws Stargate is the most brilliant concept for movie and TV. Just amazing.

So with it throwing objects. Kind of. It the traveling sales me. Problem. What the most efficient point to point. Given time. The builder of the gate would have fix the issue. They instead cheated with it. Due to time constraints.
