Ok Eric, since the proof that the above listed assumptions lead to predeterminability of outcomes is straightforward, I will be glad to find which of the above assumptions the 2 theories you linked reject. But this will take me some time.
Thanks for the discussion.

Hi Eric, maybe we are not understanding each other, but if you read my paper you will clearly see that the EPR-Bell’s version that I have re-examined do not need neither “outcome independence” nor “factorization of probabilities”. They only (implicitly) need these two assumptions (implicit in the common scientific way of thinking):
1) If there a…[Read more]

“I see no fundamental difficulty of understanding it from the perspective of a theory in which Macroreality is false, like Everett, relational quantum theory, or QBism”
Hi Eric, since I see many difficulties to give an operational notion of speed of influences in physical space without taking S,a,b,A,B as real events occurring in space, could…[Read more]

# “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 system. They just happen to occur spontaneously, undetermined, but correlated, even if at a distance”
This is not a way out, this is purely nonsense, with all the…[Read more]

Hi Eric, thanks for the comment.
#) “Note also that 1-3 are not the assumptions made by EPR at all”
They are. Maybe the presentation of the argument written by Podolski in 1935 it’s not so clear, so I’m referring actually to the later presentation of the argument in Einstein 1948 (thanks for the implicit reminder, I need to add the refer…[Read more]

Hi Eric, thanks for the reply.
#) “I gather that what you mean is that if Charlie’s observations are real, then they must be (real) hidden variables (for Alice). That may be true, but again, we do not need to make that assumption”
Independently by the fact that you explicitly make that assumption, it’s nevertheless surely true.

“However, we emphasise once more that those correspond to observed events, and note that we make no assumption
about hidden variables predetermining all measurement outcomes.”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…[Read more]

In this paper I will re-examine the EPR argument and Bell’s theorem putting particular emphasis on the relevant points for the analysis of the problem of locality (milestone of general relativity and classical field theories). I will clearly state the logical and mathematical
assumptions present in these cornerstones of foundations of q…[Read more]
