septimus, perhaps the discussion of your idea would be something for a separate thread? Personally, I don’t see where you differ from Cramer’s transactional interpretation, and as with that interpretation, I’m not sure I really see the need. As leahcim notes, interpretational problems of EPR experiments mainly focus on how to save causality in the presence of apparently faster than light ‘spooky actions’ (which I consider neither spooky nor ‘actions’ in most senses of the word). To just throw out the notion of causality does seem like cheating somehow. And of course, the problems you get are those you get with any retrocausal proposal, such as paradoxical influences on the past, causal loops (i.e. A caused B retrocaused A), and of course, there’s also the problem of how our experience of a unidirectional arrow of time comes about; the usual argument of ‘entropy was lower in the past’ doesn’t work, since for every point in time, if causal influences propagate in both time directions symmetrically, one should expect that entropy is higher both towards the past and towards the future, as the dynamics that generate entropy increase work in both directions equally well.
