It’s an untenable proposition.
I can easily posit a physical model to explain how a wave can appear to be a particle (in fact, those models already exist), but there is no sensible way for you to posit a model to explain how a true particle could appear to be a wave. The best and brightest minds for over a century have tried, and the best they came up with was “well, it changes into a particle if we happen to be looking at it, then it stops when we look away”, and that is not behavior that would be compatible with these things actually being particles.
“...well, it changes into a particle if we happen to be looking at it, then it stops when we look away”, and that is not behavior that would be compatible with these things actually being particles.”
Did you teach HS physics in 1963? You are quoting the same source as a well respected teacher I knew.
