- It seems that when a single electron hits this blob of helium, it has many possible paths through the helium in bubbles, each with a different wave function (which, as I understand, has complex values that add up to values whose magnitudes are probabilities at some point that I don't understand how to characterize). So far, I'm cool.
- Presumably (I don't see any mention of this in the articles) an electron eventually pops out of one of the bubbles, and we could (even if we don't at present) find out which bubbles were inhabited and which not.
- At that point, my crude understanding of quantum theory indicates that only the inhabited bubble(s) existed in a coherent description of passage through the helium.
- But, these guys are observing all of the bubbles, including those that don't turn out to be inahbited, and therefore according to my crude understanding shouldn't have been there.
My best highly ignorant guess is that the bubbles are all there, and the qualities of a bubble determine its likelihood of being inhabited. Even that highly ignorant guess begs a lot of questions regarding the mechanism that gives the bubbles fractional-charge-like qualities. Boy, do I wish someone with real understanding would really explain things.
