Stargate (Filter?)

[p3rtan]

I dont know if this is already answerd or if they explain it in any episode i never watched. I got to things i wonder.
1. When they dail space from a planet.
The presshure in space is zero so shouldnt the stargate suck out the air from the planet when a gate in space is dailed.

2. In one epsiode Russia dails an underwater gate. Why didnt it drown earth with the living water. And. They got a sample trough but the high presshure of the entire ocean wont be pushed through the stargate.

I just dont get it.

The stargate is able to detect when something is trying to pass through it or not.

From watergate:

DM: We had to push the engines a little harder to get through the gate, but I suspected it was a countermeasure intended to keep the water from flowing through the gate.

SAM: It's possible. My research indicated that the gate actually has the ability to measure density & molecular structure and the force being exerted on the event horizon to determine whether something is trying to pass through.

a convenient truth, more likely a plot idea that is binding to the rest of the shows, better still, to save money on the FX budget by not having water comming crashing through the gate.

[Master_Templar]

Of course it is a Plot Device to prevent that. But it works well and the Ancients are intelligent, of course that would be a thought in its design.

For your point 1:

If you're meaning a SpaceGate being dialled, not being dialled to, then the receiving world wouldn't get the vacuum of space, as there is no movement of the vacuum. If you're talking about a SpaceGate being dialled to however, air, or the lack of it would be particles, and a particle can't travel through a wormhole that isn't going in their direction(incoming/outgoing.)

The "water" in the Watergate episode wasn't really water, more like an entity that resembled it.

I don't see much logic in your questions though....

[Col. Matarrese]

well air seems to be one of those things that doesn't pass through a gate, like light. It very easily could've been built in as a feature of the gate. As for the water, I think it's as one of the above posters described.

Well the gate was designed to be versatile...i mean i can work in a blackhole, whats space or water to it?
