    Undergrad "The wavefunction never collapses"

    No from the perspective that I can see no similarly between the arguments put forward in the EPR paper and the MWI.

    No.

    Where did you get the idea that MWI does not respect entangled states? And might allow impossible uncorrelated outcomes?

    I don't understand that comparison at all. Bohmian mechanics is the complete opposite of MWI!

    I don't really understand the comparison. We still measure correlations that cannot be explained by local variables. The wavefunction itself is not a local variable.

    In MWI, the wavefunction is all there is. It is the reality.

    In MWI everything is real, so to speak. In fact, the mathematics of decoherence, treating the detector as a QM system, leads naturally to two branches. That's why the proponents of MWI are so enthusiastic. A collapse interpretation has to get rid of one branch. How does the other branch disappear?

    The branching is not a physical process. It's the usual evolution of probability amplitudes. Without decoherence, it's simple state evolution - albeit with non-locally-realistic entanglement. With decoherence it looks like a classical either-or scenario. The wavefunction itself is almost...

    It must be when the entangled state interacts with a measuring device and decoherence takes place.

    I don't see how MWI complicates this. It doesn't explain non-locality, but neither does it complicated the question of entangled states.

    Undergrad "The wavefunction never collapses"

    Here's how I look at the Schrodinger cat experiment. There are two questions: Why did the atom appear to do one thing or the other and not a superposition of both? This is the measurement problem. MWI explains this by saying that there are in fact two main branches, not one. Why was the food...

    Undergrad "The wavefunction never collapses"

    You haven't understood MWI. MWI is just regular QM without the single outcomes. It's very simple. Decoherence is complicated to get from a microscopic to a macroscopic picture. That applies to most interpretations.

    MWI is an interpretation of QM. There is only one entangled state here and only two possible measurement outcomes.
