Stargate SG1 - how the gate works question

[Sluis Van Shipyards]

I was watching an older episode of SG1 where O'Neill has the Ancient computer downloaded into his head. So Carter and Teal'c go through to another planet to try to find help for him and they can't dial out. So Stargate Command dials them and talks to them, but they can't come through unless they dial in. So was the gate always a "one way street" or was it changed later on and in the other series? I always assumed that if the gates were connected you could travel in either direction.

So are you asking why the Stargate can send radio signals forward and backward, but not matter?

 

[micdavis]

It is a one way gate. You have to initiate the dial to travel.

Radio signals only can go both ways.

Gate travel was supposed to be one way, that is if you stepped through in the wrong direction you'd be disintegrated and destroyed. That was my understanding. Electromagnetic waves can travel in both directions though, which is why radio works.

I used more words and so Mic beat me to it.

Thanks, I guess I never paid that much attention. I always assumed you could go either way once the gates were connected.

Stargate travel, from the Movie/beginning of SG-1 right through to the end of Universe has always only been one way, it was never changed. Radio signals can go through both ways hence why they're always able to talk to each other from either side. I can't remember if that part was ever actually explained though.

I just found this nice little video on youtube showing a heap of cut together clips with information shown on screen explaining various parts of how the gate works: Stargate SG-1 - Wormhole Physics 101

Mostly it's just used for plot complications.

"It's a colossal negative space wedgie of great power coming right at us at warp factor 7."

That was cool.

Wow. Apparently I was asleep through most of all the series then... :lol
