Stargate Technical The science behind Stargate increases with each episode. Discuss technology ranging from zat guns, the iris, the hand devices and of course the Stargate itself.

The Unstable Vortex

Hi everyone. This may have already been discussed, I'm not sure. Sorry if it has.

Ok, we've all seen the damage that the gate's unstable vortex can do. What's to stop it from vaporising the earth gate's iris? Or any other iris-like objects ontop of other stargates? Surely the vortex would go straight through a coverstone for example.

I could be missing some vital facts here so please correct me if I'm wrong. This has been driving me crazy! Lol.

I have feeling this has been covered, but:

a) the iris is open when the gate dials, and is closed immediately after the vortex... which is why the iris is always open when they are in the gateroom when the gate is idle. [However, I think there are occasional continuity errors where the iris is implicitly closed during the vortex]

b) the iris does not penetrate the axis of the event horizon, it is 3nm away from it. Objects which do penetrate, such as cover-stones, or the soil when a gate is buried, are what stops a gate connecting. It would seem to be a safety mechanism of the gate - it won't connect if something is already in the event horizon plane. Would be like putting proximity detectors on jet engines...

Ah, see I knew all that. I suppose it was just that I refused to believe that the iris being closed whilst the unstable vortex was being generated was simply a continuity error. Damn my stubborness! Lol.

Oh, and is it only a solid object/substance inside the Stargate's axis that could prevent a wormhole from being established?

Since radio waves are presumably penetrating even to Level 28 of the SGC, they must not affect connections. As for other non-solid things, not sure... i.e. like what??

Well for example, in 'Watergate' the off-world Stargate was completely submerged in "water". I am assuming then that only solid matter within the Stargate's axis will prevent a wormhole from being established. How is this so? Is there a scientific explanation for this or is this just yet another continuity error?

Good point - hadn't thought about that.... maybe it is just solid items. Any other examples?

Umm, not that I can think of. There may be other examples but that was the only one that really jumped to mind.

Thanks for answering all these annoying questions! They're just things that I've been wondering about for ages. It's really cool that you know what I'm talking about!

I've just thought about it and I have a theory.

The Stargate has safety mechanisms right? They detect whether something is in the Stargate's axis, and if so, prevent a wormhole from being established. It would make sense that the protocol would be induced if it were a solid substance within the axis as whatever matter passing through the wormhole would simply be destroyed once it made it to the other side. It wouldn't even re-intergrate would it? Well, water wouldn't be dense enough to prevent the matter from re-intergrating, so such a substance within the axis probably wouldn't induce the saftey mechanism and therefore stop a wormhole from being established.

Do you understand what I'm saying? I tend to over-complicate things sometimes :blush:... What do you think?

Sounds good. Solid objects could also skewer anything coming through - like a spear - which would be another reason to stop wormholes forming.

Of course, a 2 tonne concrete block about an inch away from the event horizon would allow wormholes to form but make the gateroom very messy! :evil:

Not to sound girly - but EWW!

(Of course the concrete block would need to be placed after the unstable vortex was generated ).

But still... Ew... Only the front inch of the person would be left behind! Like, have you seen 'Thirteen Ghosts'? It reminds me of a scene in that (which funnily enough centers around a character played by J.R. Bourne).

Actually (for those with a sick sense of humour) the thought kind of amuses me! Think about it... The person would step through the Stargate only to bump into this massive rock on the other side, like walking into a wall. I don't know why but I find that funny... The rest of it's just gross though...
