    All you ever wanted to know about The Iris and the Wormhole

    The show has established that there must be something physically inside the ring. This has been reiterated several times, through several worlds burying their gates, and more recently in episode 6.20 Memento when they unearthed their gate and it had large blocks ensuring that no Goa'uld could come back.

    They've also stated before that the iris at the SGC closes just a few microns from the event horizon of the wormhole, and that the unstable formation (the splash) disintegrates anything it comes in contact with.

    The iris is not blocking the gate and preventing a wormhole from forming, so why doesn't the iris have a big hole burned through it every time it's closed and an incoming wormhole shows up? Shouldn't they have to close the iris after the wormhole has formed every time?

      A very good point. But one that the show has at least been consistent in handling--there have been a few times when there was a natural iris formed on other gates (A Hundred Days, for example) and the vortex didn't affect them, either, though once the iris had been breeched, the vortex was enough to carve out that cavern that Teal'c almost died in. My guess is that a solid iris just a few microns from the event horizon somehow prevents the vortex from forming; this would be consistent with the show, though it's never been directly stated.

        The destructive vortex particles can't form when an iris is present.

        When a stargate is buryed, and is turned on, the barrier forms an iris. when it's off and burried, the gate becomes unusable until it's unburried.

          Man you guys are realy analising these things.Very interesting but I don't know what to say about it.A good theory but it won't change to show.Maybe the writers of SG-1 should pay this forum a visit because I've seen some very good ideas.They should pay more attention to the little details Maybe they do?I do not know eh Not delivering critisme on the writers.Just thinking up loud

            I believe the Iris, since its so close and it covers completly the event horizon of the worm-hole it doesnt allow the particles to form

              i'm sure it's been said somewhere on the show....

              In fact, I'm 100% sure. Watch 100 days, they had to make the gap between the stargate and the stuff it was burried in bigger with a some particle thingy so that the vortex could form, and dig a bigger cavern.

                The iris is close to the event horizon, but not too close to stop a wormhole from forming behind it. (I think the actual wormhole is supposed to be two-dimensional anyway.) And we know that the iris will not allow incoming objects to fully re-materialize, probably because full re-materialization happens just outside of the event horizon. So it would probably be the same idea with the unstable woosh effect. It just doesn't have room to manifest itself outside of the event horizon with the iris closed.
                Does that make sense?

                  So if you stood with your face really close to the event horizon of an incoming wormhole, would you end up meshed with whoever came through in a painful and terminal fashion, or would they just hit you as they came out?

                    Yes. it's exactly what I've said, basically. It was all said in 'A hundred days'....

                      the atlantis stargate energy barrier behaves the same way as the terra titantium/trinium iris. from the movie we know the unstable vortex spurts out forward and backward. maybe all versions of the gate are designed to detect an intentional barrier which prevents the forward burst

                        I say that they would just slam into you as they came out. Hard.

                        Because, personally (and I really have no irrefutable evidence whatsoever to support this theory, I think that it just makes sense given what we've seen), I say that an incoming object is almost (if not completely) rematerialized while still just on the other side ("threshold zone") of the EH. If the iris is open, the object will simply be once again re-entered into our own dimension. If not, the object will be permenantly demolecularized. Take it or leave it, or ask me if you're confused, that's just my humble opinion.

                        There was also some great discussion about this topic in the thread:
                        Matter through an event horizon **SPOILERS for 38 Minutes and SG-1: 100 Days**
                        My original "threshold zone" theory is also in there somewhere.

                          Spoiler:
                          When the gate shield was activated right before an incoming wormhole, we saw the kawoosh expand until it hit the shield and then topped, and then went back it at the same time it would of had the shield not been there.

                            i dont realy remember that but if u say so then the sheild, not being so close to the event horizon as the iris, it would leave enough room for the particles to form, however the sheild was able to resist the vortex (damn those ancients, so good with sheilds )

                              Does that mean if someone went 'splat' against the Atlantis shield that you'd see it, because they're rematerialized against it?
