      This can’t apply because unlike the portals, both sides of the ring are moving at the same speed/direction.

        The ring is not touching the thing passing through it to impart any forces. The object passing through carries only what energy it takes with it.

          Then where does the energy to displace the air on the blue side of the portal coming from?

        Yes they are though, it’s the exact same premise.

        What force is generated where on the other side of the portal, it’s a hole in space, it doesn’t transfer anything.

        Speedy thing goes, speedy thing comes out. Nothing gets transferred to or from the hole.
