Gate technology

[thekillman]

we do not know the nature of the limited range. it could be anything. including Stellar Drift, since the SGU gates do not have DHD's, which also power the gate, so power is a potential limit.

Power seems the most likely to me, but it doesn't explain why Destiny can't dial further. i'd say that it's the stargates limiting destiny in the form of the galactic identification method via the Gate Remote. the gates emit a signal but that signal isn't very powerful because the Gates have limited power

[Nth Chevron]

I still have my money on the fact they are limited to prevent hostile invasion of the MW through the Stargates, same as in Pegasus, the only gate capable of dialling Earth in the MW was Pegasus, at the very heart of the Lantean power sphere

So by this logic, saying there are not is absolutely wrong? If we've no proof that there are gates, that doesn't mean that saying there are is wrong. The Ori have to have a normal Stargate for the following to be possible:

Spoiler:

perhaps the ori created one specifically for the prior AFTER finding out about us

[Ltcolshepjumper]

It took Orlin hours to build a rudimentary stargate. Perhaps the Ori did the same after getting the information from Daniel. The other Priors had to get to the MW somehow.

[garhkal]

I also felt the Ori were the reason the prior's had stargate access, after reading it in danniel's mind.

[Rylor]

My guess is that it's a combination of two things. First, the power issue. The Destiny-style stargates are the oldest model we know of, so it's reasonable to assume that their power source was also limited to some degree.
Second, the fact that these gates were seeded specifically to be dialled by Destiny. They were never intended to be a full scale galaxy-spanning network, evidenced by their placement (corridor mapped out by the seed ships) and the lack of a local DHD.

The security issue is another possibility, but we don't know if the gates posess a security feature similar to the gate network in the Pegasus Galaxy or if they are capable of dialling further if provided with enough power.

[wingsabre]

My guess on why the SGU gates have limited range is because of power constrains. The gates don't have a DHD, and so it can't really power itself. The gates also have to be made by the seed ships, you don't want a lot of complexity in the gates being made through automation because more parts equals more chances for error. What if part of the seed ship breaks down? If it's making a very critical component, then they can't make anymore gates. As such, they needed to have a gate that's very minimum, and fairly automotive. This may also mean that there's no real network of gates, but instead each gate acts as a beacon. If you're in range of it, you'll detect it. That way, very little, to no power is devoted to maintaining the gate network, or to update it based on stellar drift. Instead both the seed ships, and Destiny will note the location, and calculate that themselves. Additionally, the seed ships travel in a single path, followed by Destiny. If you want to establish a network, it would make sense to seed the entire galaxy, but they don't do that, so it would really be a waste of energy. It would also be pointless to make it possible for a gate to travel across the galaxy. We've learned that gating long distances requires more power. That would mean that they would also have to find a good enough power source for the gates to do that, adding more resource requirements, and complexity to the network.

I agree that we have no definitve proof that the Ori had stargates before contact with Daniel and Vala. However we do have definitive proof that they were using transport rings.

Ascension does not make someone "all knowing" but it does grant a much deeper understanding of how the universe works. Certainly an ascended being would understand enough of the process to be able to construct a stargate if so motivated.
The question is whether the Ori were motivated to build stargates within their galaxy. It's hard to say. On one hand we have seen random villagers in the Ori galaxy aware of other planets such as knowing that Ortus Mallorm was on a different planet, and we know that the Priors are trained within Celestis itself. On the other hand, we have seen Priors transport Gerak's mind across the universe, and Adria has a device which could turn Daniel into a prior which probably means that a Priors staff is capable of making the transformation. Also the ascended Ori are clearly willing to interfere within their own galaxy.

We know that several Priors traveled to MW by stargate before the supergate was active. I tend to think that the Ori had a least one stargate likely built after their contact with Daniel and located within the city of Celestis which is why only Priors used it. It is also notable that aside from the Priors and Adria, the Ori invasion force is never shown taking advantage of the gate system within MW which could indicate unfamiliarity.

[garhkal]

Perhaps the Ori themselves teleported the Priors who had to 'rematerialize; out of a gate...

[Crias]

The destiny gates are a really really old first gen prototype, thats the only reason that they are limited in range. Oh and the Ori would have needed to know about stargates because the Priors used them all the time.

[Master Durangus]

The basis for limited connectiveness is seen in the chevrons. According to Carter, most of the connections are based on subspace, subspace itself does not have a "range," it's not measured by distance, so theoretically, each Stargate should be able to connect to each other. However, we find the basis of the Stargate technology (as postulated by Dr. Jackson) denying this fact.

Quick reminder: The Stargate chevrons are star constellations. A combination of 6 constellations plus a point of origin indicates an exact location, in this case, another Stargate. Dr. Jackson was first able to crack the Stargate's code when he recognized several of the constellations on the chevrons (Stargate movie).

Now, while I personally think this is a little iffy since what we know as constellations are from our "point of view." (If you took a photo from our planet, then went to another planet on a different side and took a photo, the constellation can appear different due to the difference in origin) nevertheless, that's how it works. These series of constellations (38 chevrons, IIRC?) are unique to our galaxy. This is the establishment of different gates per different galaxies (Pegasus gates, Milky Way gates). Example: The Half-Way Station between the Pegasus and MW galaxies. You saw a Pegasus gate with Pegasus-based constellations on one side and a MW gate with MW constellations on the other so that the same basis of the technology would work.

It's not the connectiveness, it's the basis of the technology. Sure, they could theoretically create a gate that had all constellations of the known Universe (probably 100s-1000s of chevrons) that would be able to dial all of them (the actual "space" traveled isn't technically relevant). But that would involve a massive gate for each gate in the system, it's much more efficient to base them galaxy-by-galaxy.

The Ori's Super-Gate probably used a very very advanced dialing computer linked to a subspace map that made it able to dial. Since the Super-Gate's did not have a pre-existing site yet were created, it's possible they weren't given their own set of chevrons (despite the SG-1 episode where they "dialed" in). It'd be unlikely that the Ori would use the chevron-based dialing system when it's not really accurate for a gate in the middle of nowhere. With their level of Ascended knowledge (and the lack of chevrons on the gate itself), it's much more likely that they identified the Supergate as a fixed position in spacetime using a subspace frequency attuned to it, so that, with a very advanced dialing computer, they simply sent the program to that pre-specified point in time, whether than having the Stargate's DHD finding the point via the chevrons.

Hopefully that's not too confusing...

[Master Durangus]

Whoops, forgot to add: Also, Orlin's build of a single-shot Stargate also lends credence to my theory that it is possible to create a Stargate and defining it in space-time as ONE point. He created a Stargate that could only go to one place when activated, probably using the same method that I described above: determining it's position in space and time, attuning the frequency of the receiving gate to the frequency of the sending in subspace and then connecting the two points in subspace.

[rushy]

OK so this is a stargate

In what ever galaxies SGU takes place in the stargates have a limited rang right? But in the Ori galaxy the gate's have the normal rage ∞ (like). The gates in the ori galaxy pre-date the gates in that are in the SGU galaxies. How dose this work people? Shame on you SGU writers.


P.S correct me if i'm wrong

You are. The SGU gates predate the Ori and Milky Way gates which in turn predate the Pegasus Gates.

Dont forget 8th Chevron address are extra galactic.

It just means it adds another distance calculation.

Also, i think the only thing that operates through subspace with Stargates is the wormholes and the Correlative update.

Stargates are in normal space and just the chevrons are used to locate them IN the real space, the number of chevrons are simply (well not simply but you get the point) spacial coordinates, when used in conjunction shrink the address from quadrant to region to sector to system to planet.

N.C

[garhkal]

Has anyone come up with a reasoning why radio signals won't work through a 9th cheveron address, unlike an 8th?

[Nth Chevron]

Most likely has something to do with the power needed to open one, the fact when you enter a 9 chevron wormhole your thrown out the other end at a greater velocity than what you entered, breaking one of Carters laws of wormhole physics.

Maybe due to the distance of the wormhole the subspace distortions interfere with radio signals because shorter wormholes arent as affected?

How long is a piece of string?

I might be wrong on this, but to the best of my knowledge, the range of a Stargate is solely determined by 1) If you have an address, 2) Ample power supply. I honestly don't think that the Ancients would have built Destiny without making sure it had enough power to get back. That being said, seeing as though they lost interest in Destiny in favor of Ascension, they probably did not figure Destiny to go so far out. We don't know if they could measure the distance from the Cosmic Background Radiation. May they did know it was far away and purposely didn't provide a way back. Those who went after it got far out were there for good unless they could devise a means to get back. However, that also being said, the Ancients probably had a way to get TO Destiny safely. I hope I didn't get to off topic.

[Crias]

Well I think the reason destiny cant dial earth back safely is probably the same reason we can’t dial destiny safely, we have no idea what we’re doing. If you think about it we only learnt how to use the Stargate 13 years ago, the ancients built the damn things. I’m sure they had a way home.

I tend to agree with this. Our understanding of the Stargate Network may be impressive, but it is certainly not as great as the people who built it.

On the other hand, the Ancients built the Stargate Network and they weren't smart enough to just turn it off (something Felger figured out accidentally) while they used the Attero Device.

Your assuming that they couldn't shut down the gate system when they may have been able to. If you were performing experiments against the wishes of the high council would you shut down the gate system? Sure sounds like a way to get noticed, especially if they can track ir back to you.
