In Stargate: Universe, there is a group of people who become stranded on a ship floating a whole long way from home. They got there by use of a planet with a special super-powered core which had the power generation to dial that distance, but the ships power reserves were too damaged by the time the new crew got there that they couldn't dial back.

However we know that the Destiny had several 'Seed' ships which preceded it, placing stargates along the entire path.

What I ask is if they (either the Destiny crew or the SGC) could find enough power sources to connect to the gates that were between each galaxy the Destiny visited, (thus connecting every galaxy, as the Destiny gates had a very low range they needed a lot of power in order to get anywhere, this is why the gates at the end of each Galaxy need an external power source), could they make a new gate bridge between Destiny and Earth thus saving the crew of the Destiny? Or were there other limitations which may have barred them from this?

And not to confuse anyone, I know why they didn't do this, just asking if it were possible from a canon perspective.

  • Assuming a gate in each galaxy could be found that could supply the required power to jump galaxies, there's no good reason you couldn't do this. But then the question presents itself, why not just use that gate to connect directly to the Earth gate? – Valorum Nov 6 '17 at 20:00

    Well it was implied that using the bridge to/from Atlantis used much less power than a direct wormhole, which was why they installed the bridge. – Benjamin Nov 6 '17 at 20:01

    I don't BELIEVE the seedships dropped gates between galaxies, just once they were there. The Ancients probably assumed that if they wanted to gate to one of the in-galaxy gates they could just use one of their high-powered sources to do so, and probably rig something up so they can go back the same way. Seeding the intergalactic void with gates is something humans do as a workaround. – starpilotsix Nov 6 '17 at 20:07
  • I realise that the void wouldn't be filled by default which is why they would need power sources capable of dialing from the edge of one galaxy to the beginning of the next. – Benjamin Nov 6 '17 at 20:17

    Millions of galaxies away, I thought, but it seems that opinion is divided. That might make a good question here, actually, if nobody has already asked it. – Harry Johnston Nov 6 '17 at 20:24

This was never directly addressed in the show, the novelization of the pilot, or the tie-in comic book. So we'll have to examine the possibilities.

The McKay/Carter Intergalactic Gate Bridge was constructed by the following:

Place gates at strategic intervals

Thirty-four Gates from both the Milky Way and Pegasus Gate systems have been strategically placed in the massive void between our two galaxies.

There are several important points about these 34 gates:

  • They were under the control of the SGC (i.e. no enemies were using them)
  • They were known to be operational
  • The locations (gate addresses?) were known

None of this is true for Destiny. If any enemies have taken control of gates, or any have been destroyed (or gotten too close to a black hole), then they aren't any good for Destiny. And do you know the gate addresses for all of them? It's possible that they are maintained by Destiny and the ship can update for stellar drift, but once you start your journey, you won't be able to refer to that.

Write macros to be able to forward someone being transferred

A macro that I have written specially for the occasion will command each Gate in the chain to store you in its buffer and forward you along to the next, and the next, and the next, and the next, and the next until you arrive here.

[...] enter the Milky Way Gate system where a similar macro designed by yours truly will forward you along to the SGC

McKay wrote two distinct macros: one for the Pegasus Galaxy and one for the Milky Way Galaxy. We don't learn much about what this entailed, but this suggests there isn't a generic macro that can be used for any arbitrary galaxy's gate system.

If I were to guess, the macro involves specific gate addresses for each gate you are forwarding to, so you would need to take the time to understand the gate system of each galaxy and know which gates are viable. Or if gate addresses don't work between galaxies, then it involves a custom gate coordinate system.

Have a space station to transfer between gate networks

Once at the midway space station you simply exit the Pegasus Gate system and enter the Milky Way Gate system

Each galaxy's gate system can't interface with each other, so you need a place to stop between systems. Destiny doesn't have Puddlejumper-sized craft that can fit through the gate, so you need somewhere to stand.

Theoretically, you could use a ZPM to go from one land-based gate to another land-based gate in a nearby galaxy in order to prevent needing a stopover point, as the SGC has used to go to the Pegasus and Ida (i.e. Asgard) galaxies. But since Stargates aren't usually designed to connect to ZPMs, you'd have to macgyver a way to connect each Stargate to a ZPM, and have more than one available so that you could leapfrog them through the galaxy. Given the difficulty that the Atlantis expedition had in finding even one ZPM, and there being doubts about if Destiny even has the technology for a ZPM, this is unlikely to be a solution.

    I do like all of this post save for the end, as pointed out in another answer, if the SGC had 2 ZPMs they could hook one ZPM into the receiving gate, then if you disconnect the sending gate's ZPM the receiving gate's ZPM will take up the slack long enough to toss the first ZPM through to the other side, rinse and repeat. Sure this would mean that any macro designed would have to be changed each galaxy but it would allow you to get through the galaxy very quickly. – Benjamin Nov 7 '17 at 20:31

    @Benjamin What evidence do you have that you can power a wormhole via the destination gate, rather than the source gate (or that it can "take up the slack if the source loses power")? There have been plenty of episodes (mostly in SG-1) where a team is offworld and can't dial the SGC because they lack power on their end, despite the SGC having plenty of power (e.g. The Torment of Tantalus, Prisoners, Bad Guys). And it's not just the lack of a DHD; they manage to get home by manually rotating the rings and connecting to an external power source on their end. – Thunderforge Nov 7 '17 at 21:28
  • stargate.wikia.com/wiki/Stargate In the tab 'Power sources' it is stated that the dialing wormhole only needs enough power to establish the connection (ZPM would be enough in our case) and then either side can use the power to maintain the wormhole. So if you hooked a ZPM into the receiving gate and then took the ZPM from the sending gate the wormhole would be maintained – Benjamin Nov 7 '17 at 21:38
  • @Benjamin I distrust wikis (see this Harry Potter question for an example of a wiki having widely-circulated false information), and it lacks any direct quotes from episodes so I can't confirm if it's correct. That said, I've changed my answer to be open to that possibility, and instead highlights other problems with leapfrogging ZPMs. – Thunderforge Nov 7 '17 at 21:54

Theoretically, yes. Practically, no.

You'd need a team and a minimum of 2 ZPMs, but it could be done. For the purposes of this exercise, we'll assume that we have enough ZPMs spare to make the full journey, though in practice the SGC would run out by the time they reached even 1% of the distance to Destiny. We'll also assume that they know where Destiny is at all times so they don't get lost on the way, which is actually quite a likely outcome.

The way this works is fairly simple.

Step 1: Use the regular gate network to dial to the edge of the Galaxy. The DHDs and internal power sources inside the Stargates themselves will be enough to achieve this.

Step 2: Hook up a ZPM to the Stargate in your current Galaxy. Doing so will allow you to dial to a neighbouring Galaxy via an 8-Symbol address.

Step 3: Send a team through the gate with the other ZPM and hook it up to the receiving Stargate.

Step 4: Take down the ZPM on the dialling side and take it through the gate. When the power source is disconnected, the receiving Stargate takes up the slack of the power requirements, which is why we hooked up the other ZPM to it.

Step 5: After you go through and the connection terminates, take down the other ZPM. Now you have the full team and both ZPMs safely in another galaxy. Repeat from Step 1 as necessary until you're within range of Destiny's gate.

Of course, even if you succeed, all you really end up with is a bunch of extra mouths to feed on Destiny with some depleted ZPMs. Even if it can be accomplished, it could only be done once and you wouldn't be able to take enough supplies with you for it to be worth it.

TL;DR - It can be done, but it's not worth doing.


This was never directly addressed, however, seeing as the Universe-style gates are capable of dialing each other (S1E15 "Lost"), there shouldn't be any technical limitations. The only potential issue comes with power - the Atlantis expedition needed to use a ZPM to provide the gate at the SGC with enough power to dial Atlantis.

So, in short, yes, there isn't anything in the show preventing them from doing so other than the power requirements.


It may have been possible but the amount of ZPMs it would have taken to get to the Destiny would have been astronomical if they had that many ZPMs it would simply have been easier to dial Destiny and throw a bunch of ZPMs through

A more practical problem of galaxy hopping would be finding the addresses you need it would come down to random dialing 8 chevron addresses and hope the galaxy you connect to is in the right direction


Destiny's crew could only get themselves home if they find their own exploding naquadria planet or one covered in ZPM.

It's plausible that they and Earth working together might be able to learn how to duplicate the assembly line of a seedship and over maybe a decade after that build up a continuous gate bridge connecting all the hundreds if not thousands of galaxies along Destiny's path. It's really all the several million ly gaps between all those galaxies that poses the problem. Considering how fast they burned through every ZPM they ever had it seems unlikely they'd ever find enough to make a round trip from Earth without a full gate bridge.

(I do think the gate factory could be duplicated given memory sharing tech plus the mind swapping communication stones not to mention the full Asgard archive including bits of the Ancient's archive as well.)

We and the writers might have missed some alternatives though.

The Stargate wiki says a BC304 with a ZPM is as fast as an Asgard ship with it's "ion reactor". Both can reach Pegasus in 4 days, almost 300,000,000 times the speed of light. If nothing else this suggests that the output of Asgard reactors is in the same range as a ZPM if not as portable. And that Asgard core can tell them how to make them. It might even make them itself. If so and assuming it's hundreds and not thousands of galaxies, they might catch up in "only" a few years.

Yet another alternative could be to steal a move from the Ori and use Super Massive Black Holes to power a Stargate connection that could skip over a few dozen galaxies at a time. Say 50Mly instead of 3Mly. The only catch is they'd probably need an FTL Puddle Jumper to move (or assemble) a local gate near to that Galaxy's SMBH. When they catch up with Destiny they'd just need to find a nearby SMBH and retrace their steps to get home.

Maybe the Priors are feeling guilty enough to lend whatever built the super gate's pieces. It'd probably be a bit more watchable if the Hammond or Apollo and some mining crew/ship were establishing 40 or so super gates along Destiny's path. Maybe with the Priors helping out to make amends for all that murder and becoming completely intrigued and mystified whenever the planet builders do something even the Ascended beings never did.


It's simple, Destiny has explored 38 different galaxies, as Destiny is following the path of the seedships before it then it stands to reason that so have the seed ships.

You cannot seed gates between 38 galaxies, the effort would take you more than a lifetime and would require resources which the Destiny Crew simply did not have.

In addition the gates deployed by the seed ships are of an older design so may have a more limited range, also add the fact that in all three series no one has ever been shown to gate from one galaxy to the next without the need for vast amounts of energy and special gates with specifically coded dialling crystals.

  • This would be better if you could edit in some sources. – TheLethalCarrot Sep 11 '18 at 14:41
  • While I don't remember exactly how many galaxies were stated to have been explored, and I'm fairly certain it was never stated in canon, I'm also fairly sure it was far more that 38. Aside from that, the seed ships have already layed a line of gates all ripe for the return home, as that is where they started, Earth. So, with all the gates already lined up and each one being able to at least reach the next gate in the chain as proven in the episode which they gate bridge to the edge of the galaxy (twice) to get back to Destiny, you only need to worry about the intergalactic dials. – Benjamin Sep 11 '18 at 14:58
  • Which, since the gate on Destiny is capable of, we can assume that every other gate is capable of. Seeing as the only gate "type" with restrictions on extragalactic dialing are the Atlantis gates, which have been specifically altered by the Ancients to keep the Milky Way safe from the Wraith. So, in my thinking, it would be feasible if they managed to get a couple of high powered devices (ZPMs) through to the crew of Destiny – Benjamin Sep 11 '18 at 15:00
  • O'niell's power booster was eventually understood/duplicated. With it a MW gate went from 90,000 ly range to maybe 180,000-250,000 ly to the Magelleanic Clouds (all the other MW satellites are either within 90K ly, much tinier and/or almost as far as Pegasus) no reason to think Destiny's gates wouldn't reach that far with a booster. A few ZPM boosted ship might reach them in 10 years and fill in the extragalactic gaps in the gate trail. Probably not the best approach but doable in less than a lifetime. – John A Aug 20 at 9:40
