- How does indeterminism appear if we look "backwards in time"?
I've been trying to imagine how a universe governed by indeterminism appears when viewed from present to the past.
My understanding is probably off here, so hopefully someone can point me in the right direction.
I'm thinking in terms of experiments such as the double slit experiment and Bell tests - as far as I understand them (an important caveat). Some of my terminology might be a little bit imprecise but hopefully it's accurate enough to convey the question I am trying to ask.
Starting with a Bell test for example, or an example where a choice of measurement is to be made.
A key element of the indeterminism is that "the future is open", that there are a range (no matter how limited) of branches that the experimenter's decision could follow. Of course, the same must also have been true of all the decisions taken in the past. So, instead of looking "into the future" we can look "into the past" . Looking into the past how would the Universe appear? Would it have the appearance of having followed a strictly deterministic path almost like a set of dominoes leading up to the present or am I mistaken in thinking this?
Let's say that we are at a point where the experimenter is about to make a choice (let's call the decision event A). If we stop and turn our focus backwards in time, will we see what appears to be a strict line of deterministic, causal events forming a chain up to this point in time when Choice A is about to be made? If we then jump into the future after Choice A has been made and perform the same restrospective inspection that has lead to a subsequent point, let's call it B. Will the universe appear to plot a deterministic line through the previous choice A, up to the new choice B?
Or will there be an broken chain leading back into the past, as such doing away with the notion of causality?
