1. I don't know what would happen if the SG team went in the opposite way. It would be interesting to find out.

2. The Stargate is Ancient technology, I'm sure they(The Ancients) built the Iris into the Stargate, probably out of a metal resistant to the gate's event horizon. Or it the Iris could be sheilded somehow.

2) Speaking of the vortex (or the whoosh, watever you wanna call it) why doesn't it destroy the iris when the wormhole forms with the iris closed?

that was because the gate was hit by a metior, which melted some of the naquadah into an iris-like sheild, preventing the rubble from sealing the gate, they had to re-melt the naquadah away with a laser-like weapon (kinda like what Sokar tried to do) and then re-dial the gate lightiening fast causing the unstable vortex to ka-whoosh out and clear a tunnel, which allowed Teal'c to drill his way out and rescue Col. O'neill.



yes, I am a nerd.

End of line.

Gate obstruction

A gate obstructed by means of burialA wormhole is prevented from forming if a significant obstruction is present inside the Stargate's ring. Consequently, it is fairly common for Stargates to be semi- or permanently sealed by burying them, invalidating that Stargate address.

Another means of controlling travel through a Stargate is by placing a barrier a minuscule distance (less than three μm, in the case of the Earth's Iris) from the event horizon, which allows the wormhole to form but prevents the reconstitution of matter upon arrival through the gate. In other words, a connection can be made but any matter trying to exit the gate will not regain its original structure, and hence will be annihilated. The Iris on the Earth Stargate and the Shield on the Atlantis Stargate perform this function, and have been seen to be used as an effective defensive precaution, whilst still allowing radio communication through the open wormhole.

Iris-type barriers also suppress the kawoosh, but are not the only way to achieve this. Several aliens, including the Asgard and the Nox have demonstrated the
