Aside from the SFX, which we all know are for show, like hearing explosions in space, there wouldn't be any noticeable travel time.
Think of it this way. An active Stargate with an open wormhole would allow you to see the other side. In fact, two people standing at each Stargate, meaning each end of the wormhole, would be able to interact with each other as if they were truly a couple of feet apart. The actual space between both sides of a wormhole would be 0. They would look like they're standing on the other side of an inactive Stargate.
As Gatefan1976 pointed out, the quantum mirror that bridged alternate realities in SG1 is close to what an open wormhole would look like but, unlike the quantum mirror, there would be no obstruction between the two sides.
Good explanation. What I don't get then is why they have that "roller coaster ride" thing when traveling via stargates? I know they've cut way down on showing that SFX on all the shows, but it's been established early on in the Stargate canon that there is travel time between stargates. They even show it playing out on a star map grid in I think the first episode of SG1. So clearly they are saying the wormholes are not instantaneous but rather require time and space to be traversed.
So, your explanation makes sense but what I don't get is how the writers of the Stargate canon explain the difference in their model?
