So Dakkanauts, I've been watching Stargate SG1.
In about four days, I've gotten halfway through season three, but I have a question that I don't believe has been answered yet.

If a person goes through Stargate A and exits Stargate B, could he go back through Stargate B and successfully exit Stargate A during the same established wormhole?

Yes.

No, wormholes are one way only (except radio/energy waves for plot purposes ). In order to get from B to A, you would need to establish a new wormhole from B to A.

Except there have been gates opened where one party has gone through from one end while something else has come through from the other (yep, even SG-1 played with its own continuity issues).

Thank you chromedog!

When was this?

Its mostly a problem only in the earlier seasons so OP's confusion is natural. Around Season 5 the show makers started getting their act together (though how a radio wave can go through but a person can't still makes no sense) but Stargate does have its continuity problems.

Officially, no. Wormholes go one way according to the canon science, but as in all science fiction (fantasy too) the rules of the universe disappear at convenient moments.

At some point in the series it was established that if Gate A connected to Gate B, and someone/thing tried to go backwards (B to A) that it would be destroyed and pretty much cease to exist. I know this happened at least once where one of their rovers came out a gate that was laying down, they got a quick video of the ceiling, and then the rover fell back into the gate and was lost.

Think that was the episode O'Neil was stuck on a planet when a metoerite hit the gate right?

Dang I miss the good ole stargates.

But also remember in SG:U, they'd have a wormhole open, going back and forth bringing supplies?
I'm not going to say what is and isn't possible with wormholes. I have no idea. but i'm almost 100% positive
that i've seen them open a wormhole and go back and forth through it in the world of SG.

Yeah that wouldn't shock me. The rules of the universe disappear at convenient moments. I didn't watch Universe though primarily because it ignores a lot of previously established canon and even has different tenets than the SG-1 and Atlantis series. The Destiny had a different kind of Stargate on it, so many that one can go back and forth? IDK what in universe explanation there is. Possibly the wormhole closed and reopened off camera.

they'd always have to redial from the planet on SG:U to go back to destiny.

But didn't they send those "Kenos"(SP?) through to look around? if it was a go, they'd go. if it was
inhospitable they'd go to the next one. sorry, i don't remeber which episode i'm thinking of. i think it was
when they were looking for water.

yeah the Kinos would go through to recon, and they'd pick it up when they went to the planet. The ship had a stockpile of the little buggers.

Kenos can be used to dial i think. Isnt that how they dial the gate when they....




As for OP. In the very first ep of SG-1 Apophis and his honour guard come and go back through the same wormhole. But that was before all the kinks had been worked out. There are a few issues through out the series though, most notable with the reintigration of matter. In one episode O'Neill steps through the gate and keeps his arm in the wormhole so that people on the other side cant redial another address. Under normal circumstances this would be impossible due to the fact that an object has to fully pass throught the gate to reintergrate and once through it is impossible to pass back, so putting his arm back through isnt going to happen. Things like this are just lovely little plot devices and should be taken in ones stride or just ignored completely.

In the first episode Apophis and his honour guard redial. They don't show it happening other than background lighting changing.

Then again, its been 2 months since I watched season 1.

You are correct. It even mentions that specific example in the wiki I linked to

Wow... I've watched that episode dozens of times but I just went back and watch the opening scene of ep 1 and i have never once noticed that the gate shuts off before.

Oh like I know how links work.

I think I only remember that because someone asked about it. I think we have watched a season a week, and that was a common question for people to ask. Hard to watch a tv show with a group of 10 people when 6 of them rotate through

alarmingrick wrote:But also remember in SG:U, they'd have a wormhole open, going back and forth bringing supplies?

Umm... when?

They never did two-way travel through Gates. The only things they allowed back and forth (as it made story-telling easier) were radio waves for communication.

The Goa'uld have a hand device that lets them dial a gate - Bahl uses it in one of the movies.
