Ra explains that there are gaps in the quarantine patrol that the orion crusaders are able to take advantage of. The ring in the article they describe is uniform/symmetrical with no weak points. All the quarantine is a bunch of guardian entities patrolling our planet. It would stand to reason if there were some kind of physical manifestation involved in the challenging of an entity, it would localized around the area the challenging occurred.
I don't agree at all with the sentiments that all things invisible are solely metaphysical. Ask yourself if the flu virus or any microbe is metaphysical because you can't see it?
I find many aspects of physics AND metaphysics fascinating. However, I personally don't feel it's helpful to just assume every single physical/metaphysical phenomenon was described in the Ra Material. Don never had the opportunity to ask about this protective ring in the Ra material because it was long before it was discovered. What if Don had asked about it, and it turns out the protective ring is a physical manifestation of Earth that needs to develop in order to protect 2D/3D inhabitants from harmful radiation (the "killer electrons" in the article)?
