I am wondering if there is a term for a certain phenomenon. I tried to search (here, google, asking folks whose coursework had more physics courses than mine [1 :) ]). But I have trouble coming up with specific terms to search, which is the original question anyway? I found several topics (about teleportation ;) ) here that discussed it directly...! ...but did not name it :) I have understood from searching, though, that this phenomenon, while common, is not guaranteed by known physical laws. That's just fine; that's not what I'm asking about. So I don't want to entice people unnecessarily to tell me about the circumstances of wormholes, teleportation, or passing through walls if you lean long enough. These things seem like exceptions to the "rule" I am asking about, but I am asking if there is term for the rule, not how to bend it. Thanks :) The phenomenon is that, generally, you can't get from any point A to any point D without also passing through all points B and C in between. Isn't there a handy term for referring to this phenomenon? For what it matters, it seems intuitive to me that this phenomenon is fundamental to observed experience, like inertia, the zeroth law of thermodynamics, or causality (though, again to admit, perhaps this phenomenon is not as reliable for physicists after all). Therefore, I wonder didn't somebody ever name it? Thank you for your time.
