TL;DR Summary
Could it be that matter exists as a wave in the past (if unobserved), until it is observed in the present?
I'm wondering if this would be a way to interpret the double slit experiment. In other words, when we observe an electron in the present, it goes through one slit or the other as a particle. However, if we do not observe it, it goes through both at once as a wave; we only see evidence of it having gone through both slits at some point in the past. As a side note, I'm not suggesting that all matter exists as a wave in the past, only that matter exists as a wave until it is observed in the present.

To put it more generally, could it be that quantum mechanics operates differently depending on whether the behavior in question took place in the past or is taking place in the present?

While these two videos may not answer your question, they can give you some good insight into how the double-slit experiment works and is interpreted today by physicists:

Having said that, we will close this thread, since we don't discuss personal theories of mainstream science subjects.
 
Got it, thanks for the response and for the heads up re closing the thread.
 
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
