Suppose we assume Bell experiments establish that Bell's inequality is violated, and that this can be interpreted to mean that hidden variables do not exist. Does this statement, if true, establish that Realism is false? By Realism, I mean the belief that the measured result of some property of a measured entity pre-exists the measurement. TY, A A "realistic" picture of entangled parties? One must be sure there is a space-time. Gisin, Zeilinger, et al., are not so sure about that. Zeilinger: “It appears that an understanding is possible via the notion of information. Information seen as the possibility of obtaining knowledge. Then quantum entanglement describes a situation where information exists about possible correlations between possible future results of possible future measurements without any information existing for the individual measurements. The latter explains quantum randomness, the first quantum entanglement. And both have significant consequences for our customary notions of causality. It remains to be seen what the consequences are for our notions of space and time, or space-time for that matter. Space-time itself cannot be above or beyond such considerations. I suggest we need a new deep analysis of space-time, a conceptual analysis maybe analogous to the one done by the Viennese physicist-philosopher Ernst Mach who kicked Newton’s absolute space and absolute time form their throne. The hope is that in the end we will have new physics analogous to Einstein’s new physics in the two theories of relativity.” -- You received this message because you are subscribed to the Google Groups "Everything List" group.
