My theory for what originally initiated particle-waveform duality is that while the physics of the universe would require particles to function deterministically, there has to be a certain amount of give in the universe to deal with the interaction of lifeforms who are chaotic in nature. This is where I believe the waveforms originate because of lifeforms generating entropy through their observations and interaction (Just look to Pauli to get a clue about upsetting experiments, or Heisenberg for that matter), those quantum states that would have originally been deterministic have to then deal with this influx of super-positioning. (Multiple Universes) This super-positioning waveform is important in regards to tangibility, If you were to decide to pick up a pencil for instance, you could pick it up in many different ways, lift it to varying heights, throw it across the room or even theoretically never have had the pencil to move about to begin with. This would mean that every atom would have to have the ability of shifting with what ever output your observable world would choose for that pencil. It doesn't of course mean that other outcomes never exist or cease to exist, it just means when you move that pencil, your linearly seeing more than one event, animate after another (This incidentally is the problem with "Absolute Rest" of a particle as it would cease to exist. I'm pretty sure even Einstein suggested there was no frame to time, no instance. [although paraphrased]). Each of those instances themselves potentially has alternative pasts and alternative futures. This is why I tried to point out that Determinism and Entropy are flip-sides of the same coin, they both play their role in the universe as a whole. Neither can rule the other out.
