Of course there is no proven interpretation, but I quite like MWI. From my understanding of the theory, the particle does not interfere with itself: the particle follows all possible trajectories in each different 'world', and we observe but one of those trajectories. Once multiple particles are fired, we are _overwhelmingly_ likely to observe a wave-like detection pattern.

One poor universe, however, sees no evidence of wave-like behaviour at all!

IMHO it's weirder than that. Here's my bad explanation of a theory, and uneducated interpretation

There's a paper out there about positing a series of non-quantum universes (particles that aren't also waves), except where each universe exerts a force on all other universes to not be identical. Apparently, under this framework, for N such universes you get an N-step approximation of the wave form (reaching the wave form as n->infinity).

Which is pretty cool in an of itself, _and then_...

We observe the wave form. Does that then mean we're observing across all of those universes?
