The physical interpretation of QM particles always causes difficulty

A non-dimensional point particle has its own conceptual difficulty, being fundamentally a singularity.

By Heisenberg's uncertainty principle, its position and momentum cannot both be (simultaneously) precisely determined.

As a probability wave, the physical interpretation is perhaps even more problematic.

One interpretation is the combination of of all the possible paths of infinite point like particles in a multiverse scenario.

This obviously has conceptual difficulties.

I personally am trying out the idea of a QM object

__actually being__its probability function,

rather than the probability function being some kind of emergent property of some other (more physical) thing.

The probability functions of different QM objects can interact, overlap and combine (as in electron orbitals or a Bose-Einstein condensate).

I am suggesting that an isolated QM object has a very broad probability function,

but that interactions with the probability functions of other QM objects will cause the probability functions of the interacting QM objects to be more tightly defined.

The more tightly defined the probability function, the more particle like the object becomes.

Obviously this has its own conceptual issues, what does it actually mean to say that a QM object

__is__its probability function.
