Whenever a stargate is opened, we see some kind of blowback, which I'm told is called a "kawoosh". If there is nothing blocking the surface of the event horizon, this forms and comes out from the Stargate, then snaps into the event horizon and is not seen again until the gate is opened again.
We've seen instances where this destroys different types of matter.
Could this kawoosh be used to destroy another Stargate?
For instance, if you are able to transport a gate to a planet where there's another and deactivate the DHD on the first one, and position the second one correctly, wouldn't the kawoosh destroy the 1st gate?
My thought is that if that were possible, it would have been possible to destroy segments of the Ori super-gate using that method.
Would that have let them use a stargate itself as a weapon to destroy almost anything?
