It's the unstable vortex that disintegrates. The vortex only forms in the middle but not out on the edges.
That's why the floor don't get disintegrated.

What I've never understood is why the iris placed over the gate in SG-1 never disintigrated!

[Nebula]

The iris was placed 1 mm in front of the vortex in the gate....

So?

[Nebula]

The iris never touches the vortex... that's why it never disintegrates....

It is close enough to prevent objects from exiting the gate and allowing them to reform.

[Dalek]

But people have been disnitegrated by the wooshey bit. The iris comes online before the wooshey bit appears so yes, why isn't it destroyed?

It's close enough to prevent matter from reintegrating, yes, but, as proven by Sokar, high energy things, like the kawoosh, can reintegrate.
Besides, the kawoosh is a vital part of the activation sequence. It can't be magically turned off by a thin sheet of trinium!

[Nebula]

just checked Gate world...

says the Iris is so close to the gate it stops the kawoosh from forming all together.

my original est was off...

The Iris forms a barrier less than 3 ?m from the Whirlpool.

[MLeo]

Perhaps the flushing needs space to form? And it only disintegrates when it actually forms? Meaning the energy (that disintegrates) dissapates before it gets to a level that can disintegrate anything.

There was that episode where O'Neill was stranded on a planet due to a meteorite crash directly onto the gate, and they needed a particle cannon to make room between the debris, so the kawoosh didn't disintegrate the debris infront of it.

Thinking of it, the flushing vortex, in real life, can also be stopped to form if obstructed (while the actual water can flow freely).

Because by placing the iris 1mm above the event horizon of the wormhole, effectively assumes the gate has been "buried". However this hasn't always been consistent, but when is anything ever 100% consistent from one episode to the next?

As has been said, its a few micrometers, not millimeters. And if it assumed the gate had been buried, it wouldn't even make a connection.

I was mistaken. You are indeed correct that it usually sits a few micrometers in front of the horizon. Enough to allow the wormhole to form, but not allow matter to reintegrate. Anyone trying to come through the wormhole will be immediately crushed against the iris.

In one episode of SG1, they moved the iris slightly which in effect made the gate appear "buried". I confused the two facts.

Acctually as I remember it, the hot rocks cooled into a very hard "case" the particle beam was used to break the hard rock case so the "whoosh" could clear a big enough room for someone to enter. Maybe the "whoosh can't destroy very hard objects?

I just checked the episode.
The rocks did form an iris of sorts. The particle cannon was used to create a pocket of superheated gas thus allowing the vortex to form to disintegrate the rocks and create an even larger cavity.

The splash the wormhole causes when it's activated is actually perfectly safe, provided you can get the entire object within it.

But people have been disnitegrated by the wooshey bit.

Jack has dived into the splash before. At least I think it was Jack. The reason it cuts that guys head off is because it expands and contracts, right? If it popped out and stayed out, then it'd be as safe as the event horizon is after connection, right?

Not in the slightest
Jack has never dived into the kawoosh. Kawalskis head being sliced had nothing to do with the kawoosh. It was placed inside the event horizon when the workhole was shut down.

[NeoKaede]

Yeah, the splash always kills organic beings (remember that first season episode when SG1 ended in a prison cavern and those guys were throwing themselves into the vortex to "leave"?). I suppose it's some kind of residual energy that can't cut through hard materials, and that's why burying the gate works.

Imagine when someone finds a quarter of a head in some forgotten planet on the other side of the galaxy :lol:

[Darkthunder]

It's also been estabilished, that the gate doesn't "transmit" anything until the whole object has passed through the event horizon (SG: Atlantis episode). Thus, I doubt any piece of Kawalsky's head would've ended up on some remote alien planet

Ah, but as soon as it is cut off by the closing wormhole, thats is a whole object since it isn't connected anymore.

[Nebula]

No the head is lost... when one gate shuts down the other gate shuts down....
No time to transmit anything...

Remember that ep when.. was it Tilk?.. who got stuck in the gate... after the sending gate was destroyed??
