How does the so-called "many worlds" interpretation of quanta explain the double-split experiment?

Question

Everett's "many worlds" proposal apparently bypasses the contradictions and explains the interfering probability waves somehow, but I don't understand.

Answer 1

I'm not   sure who Everett is, but I don't think you can use the many worlds approach to explain the double slit except in a really convoluted way.  If you accept that a quantum phenomenon is described by a probability function and only one probability is realized when the event is observed, and, by definition, all the other outcomes are excluded (can't be realized simultaneously), then each electron or photon passing through the slit can only appear once on the detection screen.  Now you could use many worlds to say that the observed pattern generated after repeating this experiment many times is just a superposition of different worlds.  Pretty convoluted and implies there is only one electron or photon in the experiment and that the many probabilities get superimposed to make the observed pattern.
