We never see the wormhole in Stargate, at least under SG1 canon. It's microscopic and simply used for transporting a matter stream. The ring field is a matter destabalizer and recombinator, pretty much the same thing as Star Trek transporters. Thats why radio waves can move two-way but matter is one-way.
Now if you're using Movie canon, yeah, it's broke.
Also, Marvel? Those aren't wormholes, they're magic portals.
Yeah, even if a wormhole is involved, the "surface" is some local magic machinery designed to make the trip survivable and ensure you pop out in the right shape on the other side.

The second video is about how the first video was made.
Seconded, and don't worry, the initial art gets a lot better over the decades. :)
