It's even weirder than that, though, because with lazy evaluation you still have a complete description of the state involved; it's just a matter of unpacking it by executing the description. That's more analogous with a hidden variables theory. With retrocausality, it seems that performing an observation fundamentally adds information to that which has been observed.
If retrocausality can be likened to a computational mechanism, I'd be really interested to know what it is! Like I said in another comment, it seems like there's some element of monotonic computation involved, but the brand of monotonicity is quite unusual.

- RobertoG 9y ago>>"it seems that performing an observation fundamentally adds information to that which has been observed." disclaimer: I have not idea what I'm talking about. Is it not that the "adds information" that you mention, it's like sampling a probability distribution? Of course, then your program, the universe, it's not deterministic anymore (but I think that it's already the case when quantum physics is involved). So, your lazy function, don't do anything until is required and then it returns a sample from a probability mass function (not a pdf because we are talking quantum here).
- cma 9y agoNo. See the Kochen-Specker theorem. You can choose which way to measure in ways that sort of interact with one another statistically even after two particles are far separated.
- neolefty 9y agoCan anything be "forgotten" once it's been determined? For example--can two entangled particles be created, then forced to interact in a way that collapses their wave functions, then sucked into a black hole, without having been observed by anything that isn't sucked into that black hole--does their collapse matter? Does the universe forget it? If so, then could the whole universe be a reversible computation, once it's summed up from big bang to big ... whatever happens at the end?
