The Metaphysics of Quantum Mechanics

The three major metaphysical aspects of quantum mechanics are:

1. Particle-wave duality.
2. The role of the act of observation in creating reality.
3. Nonlocality (spooky action at a distance).

Particle-wave duality and nonlocality, as metaphysical as they may seem, are aspects that have been observed experimentally and so would seem to be definitely a part of our physical reality.

But what about the quantum mechanical formalism that the act of observation actually creates reality? The central problem, of course, is who is the observer?

What do you think?

This is an interesting issue. It's worth pointing out in the beginning of the discussion that there are interpretations of quantum mechanics that do not require wave function collapse. For example, the Many-worlds interpretation, or consistent histories interpretation.

The one interpretation of QM I am absolutely certain is wrong, is MWI.

Care to share some more details?

I'd say its like trying to see a boggarts true form

They say you create your own world, in some aspects it may be but to a certain extent only.

Boundary penetration is more mind boggling to me personally, those crafty particles!

If you are viewing this on a laptop, consider this: your laptop gets so warm partially because of quantum tunneling. The electrons in the semiconducting computer chips "leak", and it's called a leakage current.

Their still crafty ;) Hot crafty things LOL!

I've actually spent the last 2 weeks going over this topic in my QM lectures, the maths i get, its just the idea

Not without going all spiritual...

It isn't something I can prove with either science or logic. My reasons are based on personal experience, which isn't much use in a debate about the metaphysics of quantum mechanics. Well...apart from maybe the fact that there's any such thing as "personal experience" in the first place.

Fair enough.

Nice. It's good you understand the maths - they are generally not easy. Which course is it?

I think having an understanding of the math gives one an advantage. It doesn't fully illuminate some of the philosophical matters, but it definitely demystifies many of the common concepts (e.g. "wavefunction", "uncertainty relation," etc).
