In this episode the presence of a blackhole near the distant stargate means that the team are unable to close the wormhome. When they realise that objects (smoke at first) was being drawn to the 'gate they guessed that it was the blackhole’s gravity that was attracting the objects.
The response was to close the iris. Later in the show, when the gravity became too strong and the iris was ripped apart, the effect of the blackhole’s gravity in the base was increased (people being dragged towards the stargate and such).
How is it possible that a piece of metal could have halted the effect of the 'holes gravity? Surely it shouldn’t have made any difference?
It’s Standard Operating Procedure to close the iris at any hint of threat, so they closed the iris as an automatic response. I doubt that the iris blocked the power of the black hole at all, the black hole kept pulling just as if the iris wasn’t there, but as long as the black hole wasn’t strong enough/close enough to pull the iris apart, smaller things (like air) wouldn’t be sucked through.
I haven’t seen the episode lately, so I don’t know if they actually say, “Oh good, the iris has decreased the power of the black hole! For now.” But assuming they didn’t…
I agree with Rysler. Everything was getting sucked toward the Gate - the iris made no difference. The effect of the black hole was increasing anyway. Hence the whole “world in danger” scenario.
I think “wizard” is about the right answer. Strictly speaking, the iris should have made no difference. But it’s positioned a few angstroms above the event horizon of the wormhole, so make up your own technobabble about the gravitational energy being prevented from reintegrating.
Could someone explain the ending of that episode? To close the wormhole, they…
used a bomb to pump a ton of energy into the stargate, which caused … what? Somehow, this solved the problem, but I didn’t understand what the bomb was supposed to do.

“OK, but in the scene where O’Neill & Cromwell are going down the ropes to position the bomb - the iris gives way and both men are suddenly jerked closer to the Stargate as if there’s a sudden increase in gravity. Which shouldn’t happen.”
My no-prize explanation: When the iris went, Earth’s air began to be sucked into the black hole. This caused objects, such as Air Force Colonels, to be pulled toward the gate by the airflow.
For example, take your vaccum and but a piece of cardboard infront of the hole. Nothing will get sucked through. Drop the cardboard and you’ve got suction. Basically the same thing, except a much bigger vaccum.
Great reference. Who here knows where that comes from, and further, who here has, in their very, very early youth actually sent off a letter requesting a no-prize and waited patiently expecting to actually get something?
That’s the one Diceman .
IIRC correctlySG-1 were under fire, O’Neill and Carter were jsut behind the other two and there was an explosion just as they enetered the gate which threw the wormhole just slightly off course.
