Demystifier's latest activity

"Correlation" might not be the best word to convey what has a causal effect. The point is that the A and D measurement results happen...

You are right, in the meantime I forgot what i) and ii) have actually been saying. :D The reason I ruled out ii) is because there was...

I agree, and I certainly agree that that's the position Bohmian mechanics takes, which is why I chose ii). :wink:

Are you sure you don't have the choices mixed up? Here they are again: i) seems like the one that is problematic if you don't want...

This, in essence, is very simple. Consider a product state $$|\psi\rangle = |A\rangle |B\rangle$$ Any state can be written as a...

Thanks @Demystifier! :smile: Indeed, I had never stopped to think about how important the post-selection role is in preparing Hardy...

There is no arrow of time in the microscopic regime. But the entanglement swapping involves measurements, and measurement is always a...

The main issue is - can an event in the future cause another event in the past? I say it can't. Let me explain. The very notions of...

Understood. I thought @Demystifier was saying that description explains the change in physics. My misunderstanding.

The Hilbert space doesn't change just because you make a measurement or perform a unitary operation. The full Hilbert space describing...

No.

Since @Sambuco talks about electron-positron annihilation, I would like to draw his attention to the Hardy setup...

Even if I accept that there is free will, not merely in some weak/illusional/emergent/compatibilist sense, but in the strong fundamental...

It seems to me that you fail to grasp the notion of a Hilbert space at a sufficiently abstract level. To understand it properly you have...

I think neither option quite follows. The future swap does not need to cause the earlier A/D outcomes, and the earlier outcomes do not...
