QM as written in mathematics is a very ugly beast, I saw a great blog post on ithttp://theeternaluniverse.blogspot.com.au/2009/09/just-how-prettyugly-is-standard-model.html
Now that's a lot of very complicated mathematics which looks like nothing how we see the world.
Now we have place QM firmly in it's position in the universe as a fundamental property of the universe we have to deal with the measurement problem.
Our initial attempts at the interpretation had invisible waveforms etc.
In the post 2008 era we now understand quantum decoherence is what the early interpretations tried to describe
Decoherence does not provide a mechanism for the actual wave function collapse; rather it provides a mechanism for the appearance of wavefunction collapse. The quantum nature of the system is simply "leaked" into the environment so that a total superposition of the wavefunction still exists, but exists — at least for all practical purposes — beyond the realm of measurement.
What all that is telling you is that the universe extends outside what we can see and touch ... above they call it ... beyond the realm of measurement.
The previous post article I linked brings in GRAVITY and unifies it with QM is this hidden realm in a scientific way.
What I am steering away from is "consciousness of an observer" arguments
I take an out on this mumbo jumbo as do most scientists
=>To many scientists the dualist interpretation fails a priori to compete with other interpretations of quantum mechanics because "consciousness causes collapse" relies upon a dualistic philosophy of mind (in particular, a radical interactionism), which is inconsistent with the materialist monism presupposed by many physicists.
I am a very very very materialist monism person
