They say that action at a distance is "not compatible with special relativity" but retrocausality is because it's not full retrocausality (can't send signals back in time) but just a weaker kind. I think they've missed the point on that as they've just copied the argument for why action at a distance is compatible with special relativity.
- simonh 9y agoThat's not what they are saying at all. Your pre-judging the outcome by calling the end result 'action at a distance', but action at a distance is a proposed explanation of the outcome, not the outcome itself. That's what they are trying to explain. Retrocausality is an alternative explanation of the outcome to action at a distance.
