|Quantum mechanics: is a partial discipline of physics, dealing with processes at the level of elementary particles. Here, principles which cannot be observed at the level of everyday objects are valid. The special forces and interactions that prevail within the quantum world are not to be found on the macro level. See also superposition, entanglement, uncertainty principle.|

|Genz II 291
Quantum Mechanics/Interference/Mirror/Wheeler/Genz: it is not about interference at all.
N.B.: it is about the presence or absence of the second semipermeable mirror which does not allow the assumption or allow the photon to take any particular path. If the mirror is in its place, both paths must have contributed.
N.B.: the experimenter can make the decision in the course of the experiment!
((s) That is, after the photon has already passed the position. ((s) > backwards causality)
Gravitational lens effect/Genz: here the same principle plays a role, the photons have perhaps been traveling for millenniums, after they have passed the galaxy. Later, it is decided which way they have "taken".
Wave function/quantum mechanics/Genz: the wave function states that the photon cannot be assigned a single way around the galaxy.
Delayed choice/quantum mechanics/Genz: the delayed choice amplifies the oddities of quantum mechanics.
Copenhagen interpretation/Genz: Genz does not admit any reality to the quantum world. Therefore, Wheeler's "smoky dragon" (which makes the intermediate steps unrecognizable) is not needed. Therefore, it does not allow the "ghostly remote effects" (Einstein, Podolsky, Rosen EPRVsCopenhagen interpretation) as an argument.
Delayed choice/semipermeable mirrors/Wheeler/Genz: his experiment can clarify what the principle of free will forbids (see above): For example, it could be that with the decision whether the photon chooses one or the other way, also the other decision is made,...
...whether the experimenter will install one or the other device.

Wheeler/Natural laws/Genz: Thesis: God must roll dice, otherwise we could not understand "his" laws. ((s) initial conditions are more understandable than natural laws which would be arbitrary).
Law/Wheeler: thesis: every law will ultimately prove to be statistical.
