Thinking about concealed possibilities;
Possibility, defined by Oxford languages 1. “noun
a thing that may happen or be the case.”
The Schrodinger cat thought experiment showcases the type of situation where a possibility may have been extinguished but this is not known so the now impossible is retained as a possibility, though this is incorrect. Smelling poison fumes escaping the closed box could be used as an indication that the live possibility has been extinguished.
Viewpoint or context ‘seen this way’ measurement protocol yet to be established is a different situation. The possibilities remain vital, only being extinguished when a relative viewpoint or measurement protocol is used to give a new singular observation or measurement outcome.
For a macroscopic object subsequent observation or measurement is still possible, depending on how the experiment is conducted. So to say that other possible outcomes have been extinguished is not necessarily true. It is true where only one outcome can be obtained. Such as in subatomic scale experiments or a destructive measurement protocol. At any scale is used. Application of different viewpoints or different measurements can give different outcomes.
This is relativity, an extraction from the absolute, existing, material template that embodies many possibilities. The ‘many worlds’ of possibility are not in the limited relative outcomes, but preceding them as a material. observation independent, Object reality.
