We can only understand things so far as we’re able to analogize them to something tangible in some fashion.
For example, if that was your most vivid analogy of spin, then in some very true sense, for you, the Universe is ultimately filled with mobius strips of colored paper traveling through the tines of unseen forks.
Or if spin was visualized best by the Bali dancing cup trick, then the Universe is filled with very tiny dancers with two arms moving cups around their bodies.
Even if you mentally can move past the initial analogy (or metaphor) that gets you there, it all comes back to that first connection to reality. It also points to our limitations as a species; I believe we ultimately can only ever go as far as we’re able to analogize, in some form, to something tangible. We may move beyond what’s tangible, but it’s built upon tangible metaphors.
If something comes along that we cannot, in some way, model in some fashion, whether with physical analogies or mathematical analogies, we’re screwed. We will be unable to comprehend it at all.
