It's painfully easy to have a clear intuitive picture of quantum physics. You just have to ditch one concept.
Universe is not made of little balls.
Particles ARE their wave functions. Nothing less, nothing more.
Sometimes those two wavevy objects interact as if two little balls bounced at one point, but that's only "accidental" similarity between the way they exchange the energy (and momentum) and the way macroscopic balls exchange the energy. Yes. It's not deterministic, what will be the parameters of that interaction. At what spot exactly will it seem to have happened, how much energy will be exchanged and how will it reshape and redirect the inital wavy objects. But thanks to our math we can predict likelyhood of everything that might happen.
Well, not exactly accidental because the way macroscopic balls bounce comes out of the exchange of energy by microscopic wavy objects bound tightly together. Same way that macroscopic magnetic interactions come from microscopic interactions of many thightly bound and oriented particles.
Wave functions never collapse into little balls, they just interact as if two balls bounced, and they get reshaped to be smaller and less fuzzy, but that's it. You can easily spread them back by interacting with them again in a different manner.
There's no such thing as a measurement. Measurement is just interaction with large rigidly bound chunk of matter which reshapes the measured particle because any interaction always reshapes.
There's really no reason to think that particles are little balls or matrial points or anything similar.
Initially people thought that because of photoelectric effect. That energy is transferred in quanta. But it's not hard to imagine this as purely fuzzy, wavy phenomenon where electrons are stuck around the nucleus in a sort of "harmonic" and they can't jump up to the place half-way to their next more energetic harmonic. Check out how orbitals look (and Chladni figures) if what I wrote seems unclear.
If you know any reason to think particles are little pointlike objects please let me known because I couldn't find any.
