Immediatly after observation an electron is in a definetely known place. A while after it is described by a complex valued field that is quite spread out spatially.
Combining many spread out complex fields can add to much narrower fields.
In QM sometimes superpositions evolve into non-superpositions in a perfectly predictable manner.
Having one facet of the superposition definetely locked in and knowing that the future state is going to be perfectly non-superpositional means that the fields of the other parts of the superpositions are perfectly locked in (so that they exactly cancel).
If these were missing then the result would be superpositional (keeping the directly observable part fixed)
Therefore the other parts are definetely there.
Even keeping the directly observable part constant there are still degrees of freedom what the other parts could be / are doing.
Quantum odyssey: + blue-blue, - blue-red, keeping left-side blue constant the right-side determines whether a hadamargate spits out a deterministic 0 or 1.
H(|0>+|1>)=|0>
H(|0>-|1>)=|1>
H(|0> + 0|1>)= H(|0>) =|0>+|1>
H(|0> - 0|1>)=|0>+|1>
There are two timelines where there are two different electrons. Then an event happens and after the electrons in both worlds are in the same state (also implies same field). In order for the evolution to be lawful they need to take hints from each other. Because the electrons before are different their field spreads are diffrent. This means there are outcomes that are allowed for one electron and forbidden for the other. In the case that the fields allow the transition when looking at each world separately there must be states that are allowed for both. In the case the electrons end up taking the same option the laws of each world separately do not feature any extra "kick forces" not explainable within just that one timeline.
One electron spreading to a spatial superposition overall is a valid QM process. QM is T-symmeteric so a spatial superposition converging to a single electron position is a valid QM process. QM laws are sufficient to do this, there are no extra choices needed or possible. If you consider each point in isolation on what things QM would allow to happen there, there are some field areas that do not come to pass because the situation is not actually isolated (ie position A has + somewhere and position B has - in the same position and when we take note of all the positions the sum ends up being 0 - there can be no electron there). In the merging process the different parts of cloud are sufficient to guide every part eventually to a single point. The indeterminism can be completely removed by the infuence of other parts.
Whether the situation is extended in space, time or possibility the essential mechanics stay intact. The time aspect of the dunamancy is connected to where electrons will arrive or where they came from. The possibility aspect of the dunamancy is connected to what "could have happened". But it actually happens as its non-happening would make its guidance vane.
Because QM always knows what to do, that you have a spread over possibilites means you have an incomplete picture. Either there are many subpossiblities that all take place ("underneath you", scattering, the electron goes "everywhere") or some of the possibilities will not take place as there are possibilities parallel to you that preclude them ("above you", convergence ,electron gets guided to pick only a small subset (pilot wave theory is both right and wrong)).
Compare and contrast meta-time deterministic universe being only approximately time consistent (Achron). Best chronal theory will have gaps in it (essentially whether the grandfather paradoxer traveller will appear dead or alive, which can not be removed by more chronal evidence) while having general inductive utility. Achrons can get to a point where they do not have to be surprised.
(come up with the possibility equivalent of the the time-side term "chronal" ("reading steiner" is somewhat but would benefit more from strictly possibility one instead of a more general mix of dunamancy))
A way to get a hold of convergence is to combine the fields of the possibilities to obtain that narrower field. Keeping the "local timeline" fixed many such guidances are possible (each foreing timeline providing a unique spin on what happens). Summing up all the foreign timelines would get you back to the original single timeline spread (symmetry of spread and convergence, hadamar is the gate of spread and the gate of convergence (or should it be called "recoherence"?)).
Quantum fluctuations as unforeseeable convergence pulls from far-off possibilities. Gravity as convergence pull (stuff like the Outer Wilds probe would have lesser effect compared to more deterministic stuff (astronomical uncertainty muffles rotation speeds?) ).
