As a side note, my idea seems to be interesting,
but it can be completely stupid. (No Everettista
was able to answer though, since long time).

It is possible to think that when the charged
particle hits the little scintillating surface 
'm', at time 't1', a split occurs.

After this split we have two worlds: A and B.

In world A the charged particle hits 'm' at time
't1' and the observer sees the flash. That is
the end of the story.

In the world B the charged particle does not hit
'm' at time 't1'. But the observer (who knows
the setup perfectly) at time 't1' realizes (if he
believes in MWI) that a split already occurred, 
and that he lives in the world B, where - at a 
later time 't2' - the charged particle will hit 
the face of the box.

In this case, perhaps, we cannot say that MWI 
is just the 'minimal' and 'mere' implementation 
of the QM (linear) formalism.

And the solution above seems to presuppose a sort 
of Newtonian time (which in QM is a difficult
