Neve said so, I'm just embracing the MWI and asking questions based on the answers received here on the thread. The post you quoted was...

But in the MWI, all branches correspond to actually occurring outcomes. In Bohmian mechanics, only one does. That's a big difference.

On the first point: agreed, the ontological claim is different. But epistemologically, the observer's situation is the same...

Thank you. If there's no settled version, isn't the branching structure underdetermined? Thank you for the correction on Bohm. But the...

Both have a non-local universal wavefunction that contains all outcome information before measurement. Bohm selects one outcome, MWI...

So MWI has a non-local variable (the wavefunction) that contains all outcomes from the start. Isn't that structurally a non-local hidden...

If the wavefunction is the reality and branching is not a physical process, then the branches were always there, nothing is ever...

I'm not defending Copenhagen, I'm happy to analyze that too. But let's finish with MWI first: you said the branching is "not a physical...

Thank you for the honesty. But if "the branching is not a physical process", in what sense are the branches real?

Thank you. Let me make it concrete: A and B each send a radio signal to C with their result. The entangled state can only interact...

I'm not saying MWI complicates it, I'm asking a simple question within MWI: when do the worlds branch(decohere) for observer C? This...

let me believe in MWI: I will add observer C who receives results from both A and B. In MWI, when exactly do the worlds branch for C...

That's exactly my point, there is no global "instant," so different observers see the branching in different orders. Observer 1 sees...

I'm not questioning what MWI is. My question is physical: if the branching occurs at different spacetime locations for Alice and Bob...

Agreed, only 2 outcomes. But when did the branching occur? At preparation or at measurement? If at preparation, then the result was...
