Hi Federico,
As I said, I have read your paper. But you do not provide a proof of that claim there. I’m saying that if you try to prove it you will find that you will fail, because there is a constructive example of a model that satisfies 1 and 2 above and reproduces quantum correlations (namely quantum causal models). In fact people even study…[Read more]

“could you give me some references where these interpretation account for that?”
This debate has developed in most detail in the case of the Everett interpretation. For example, Deutsch and Hayden, for example, have argued that a notion of locality can be maintained in Everett, and the notion of locality that can be maintained is essentially…[Read more]

Hi Federico,
“If you reject this principle (and I think that it would be even worse than the solipsism option) you would invalidate all the scientific knowledge we have. At this stage it would be useless to talk about locality or everything else. The hypothesis that causes are in the past and that correlations need an explanation in my opinion is…[Read more]

Hi Federico,
“The reality of the spatiotemporal events S, a, b, A, B (S is the process of emission of particles in the source) is a necessary condition to define speed of influences and so locality in physical space. In fact this is an implicit assumption of EPRBell argument/theorem“.
I agree that it is an implicit assumption in the EPR/Bell…[Read more]

Hi Federico,
One of the ways around the conclusion of predetermination, even while assuming Macroreality, is the “passion at a distance” resolution à la Shimony: the measurement outcomes happen to be correlated in the appropriate way, but it is not that one of the outcomes causes the other, or objectively collapses the state of the distant…[Read more]

Hi Federico,
Following up on our previous discussion, now that I’ve read your paper, can you provide a mathematical proof that assumptions 2 and 3 in your paper lead to predetermination of measurement outcomes? This should help clarifying that you actually need an extra assumption apart from Parameter Independence; i.e. you need an assumption…[Read more]

Hi Federico,
Thanks for the comments.
“Regarding the first part of the quoted sentence, I would like to note that from Alice’s perspective those events observed by Charlie are not more real than hidden variables (or than Bob’s measurement choices and outcomes) until Alice become conscious of them“.
Your comment seems to already deny one of the…[Read more]

Hello Wayne, Travis,
I’m sorry if you are already tired of this discussion, but having read your paper and the discussion above, I’d like to add a couple of thoughts, and would be very interested in your opinion, Wayne.
The main puzzle for me is still whether or not a notion of agency is at least implicitly required in order to make sense of…[Read more]
