How strong is a Stargate?

[PTeppic]

In seaons matter of time it is not giving too much away to say it comes under the influence of a black hole...

So - given the gravity effects on P3W-451 where the gravity source is - wouldn't that gate simply collapse under the intense field strength?

 

[ColONeil]

It must be pretty damn strong, it survives an intense strenght, and a big bam from General Bauer

Yes the gate would quite quickly collapse due to the gravitational forces of the Black hole. However because of those same gravitational forces the gate would experience the flow of time at a different rate to an outside observer. Therefore a hundred years might pass on Earth in the same time as a minute does for the gate.

As seen in "Exodus", it is still possible to dial up the black hole gate, even though it has been two years since the gate was drawn in. See the episode to hear Carter's theory.

Spoilers.

















Also remember the stargate took a direct hit from a meteorite in the episode a hundred days.

Maybe if threatened by such a large force of gravity like in that ep the gate has systems to convert or redirect those forces to prevent it's demise? Them builders were smart. I think the Tauri meddling with the gate sorta threw the system a curve and it maybe malfunctioned in some way? Just a thought.

 

[PTeppic]

I think this is in another thread somewhere... since a lens usually does not itself self the intense effects of the beam being focused, the gate does not appear to suffer from the gravity which flows through it.

I expect that the "usually" part would be those not in an enviroment of intense gravity influence. Put a lens into gravity and the action of the lens would be different because of the effect of gravity on the lens. yadda, yadda. The nature of all those forces like light and gravity start to change when space gets warped. At least according to what I understood of that grand unified theory people were sputtering about ten years ago.

I didn't really think that there was a physics analogy for the idea I was trying to put down. It's been awhile since high school physics.

 

[PTeppic]

Lens/gravity - true.

But - the physics is made much worse by the lens being the wormhole itself, and therefore already something almost beyond physics, and potentially space-time itself. So, the lens is at two points in the galaxy, appears at the SGC end (for example) on the centreline (presumably) of the gates depth axis, but the gravity field is perpendicular to that axis....

Need new head - this one just exploded! :dead:

Sorry to hear about your head. The head fairy will be by Friday...
I took a bit of a peek at the episode in question. I think they did a pretty good stab at making the idea remotely science plausable and all the reasons why the bomb would disconnect the gate at least made sense in light of other episodes. I'm happy when a science fiction show actually digs into a bit of science. The time warping on planet and time warping bubble around the 'Gateroom thing gets a bit thin for the armchair scientist like myself because an explanation behind that would get to be really involved. (and maybe need input from that Hawking chap to make much progress) In some way the 'gate was acting as a containment system as well as a lens.

But another instance where time was given a nod was in "Tangent" where delayed radio transmissions were part of the story and if not strictly correct, at least given a nod. And since you mention exploding heads, the means of rescuing Jack and Teal'c got a bit of a short shift towards the end. All ya have to do is rent the movie "Event Horizion" with Sam Neil to see a bit more acute, acurate, and graphical example of exposure to space. Or, "Outland" with Sean Conery. Now, there's an old movie! :freak4: Gosh, I'm suddenly wondering if that rescue part is a rip on H2G2 where Dent and Ford are picked up by the Infinity drive. Remember the mantra "it's just a show,it's just a show..."

Actually, all you really need is heat. Everything has a melting point, or at least a temp at which it becomes flexable. I believe that the Ancients found the melting point for Naquita(sp?), and molded the peaces for the gate.

If there was no melting point for Naquita, how could the Stargates exist at all? Unless the ancients just stumbled appon a few hundred naturally formed rings with interlocking parts that just happen to estabolish intergalactic wormholes between one another...

...also, the fact that each Stargate is exactly the same, identical to the last detail, suggests that the Ancients melted the Naquita and poured it into molds to create the parts, therfore each gate being identical.

 

[PTeppic]

...or carved HUGE slabs of mined naquadah, perhaps using energy beam chisels.

I think the more likely, since we know naquadah can be fed into a reactor, is that like any mineral, has a melting point. However, you would perhaps have thought that direct hit by meteorite would get close? Perhaps not.

Each gate isnt identical, as each planet has a different point of origin the Glyphs have to be slightly different, also each Stargate which is on a different planet has a different set of constellations so basically each one is slightly different.....

Just remember the Tollans built there own Stargate.....

[PTeppic]

The Tollan gate apears to be the only new gate in perhaps thousands of years since the Ancients left the galaxy.

Despite the reality of actual constellation appearance in the sky, as disgussed in perhaps another thread, all planets seem to use the same single glyph no matter where they are located - apparently based on the view of that constellation from earth.

However, there are, in some cases, other galaxies/planets represented which are new. These appear to be the minority, since they are all within the same galaxy anyway. [With at least one notable exception.]

Makes you wonder if the Ancients came from earth...

i was under the impression that a wormhole could exist without a gate. and then you have 2 factor in that whole time distortion... never mind.

Well, they are still theoretical to earth physics, even to the point of the start of SG-1 although they seem to have guessed/deduced that this is how the gate system works before the first mission. There is just too much inter-stellar monitoring equipment not to think it was a travel device.
