So. I never watched the show in order until recently. Im on the late season 2 episode with the wormhole and I think I was scratching my head before with some other episodes as I thought it was two way. That episode finally made it clear it was one way. Also will add a mildly infuriating but do a community search for stargate does not bring up this community.
Great analogy! Also goes well with that big “splash” when you first connect
Yeah, whole knows what kind of scary physics is going on with that pretty splash and whirlpool as the gate manages to fight for stability.
