OK, I like Omnes too, and Fuchs and Peres. But their view is that the wavefunction is just a calculational device thru which we make predictions. So the collapse of the wavefunction is just us learning new results and revising our prediction.

But you seem to have a more physical model of what happens, "...when the frame of the particles and the observer are aligned by a common dimensional event (the measurement of the spin of one particle by the observer) that both frames become aligned and thus the spin of the second particle becomes apparent in the observer's frame." Does this alignment have a randomness?

Brent,

Sure, of course. I see what you mean now. Omnes is of course correct. That's what the equations tell us, that the results will be probabilistic. It's Everett who is off his rocker here by trying to impose some outlandish alternative interpretation....

    But it produces probabilities.  And the experiments confirm that the 
measured values
    are
    random with the distribution predicted.  But each measurement only produces 
one of the
    probable values.  So the question is how do you get from the probabilities, 
which is
    what
    QM+decoherence predicts, to actual realized unique values?  Omnes just says 
what do you
    expect QM is a probabilistic theory.  Everett says they all happen every 
time with
    different values and we 'happen' every time as observers with correlated 
experiences.

    What do you say?
