There are no particles, only waves. I do not know how long it will take people to accept this because I think it effects their very psyche, realizing that there is no mass outside of our observations.
The wave went through the slits, not the "wave function". There is no "quantum" because there is nothing to measure so there is no quantum physics.
The fact that we are quantifying things is the problem. When we look at everything as a whole which is effected by waves we will find the solution.
