Physics, Astronomy & Cosmology / Re: QM puzzle: Is a measurement being made in the 2 slit experiement all the time?« on: 02/12/2023 05:57:23 »
Let's just assume that the usual QM stuff does apply and I'll choose the Copenhagen interpretation of QM for this problem.And there is the source of your conundrum. All the stuff about measurements and wave function collapse are reasonably predictive models of reality but can't claim to be reality.
If you want to pursue the wave function model, it isn't actually zero anywhere, just infinitesimal in most places.
And yes, it is almost impossible to do any useful experiments with free electrons of less than about 1 MeV in anything less than a fairly hard vacuum. The range of a 1 keV electron in ambient air is about 0.05 mm.
