QUOTE (Leonardo @ May 14 2008, 11:09 AM)

Take the collapse of the particle wavefunction as an example. This is effectively states the observer is the cause of the collapse of the wavefunction, however God is the ultimate observer. He is everywhere and sees (observes) everything. If God existed there could be no wavefunction collapse as He would already be observing every single particle in the universe.
I'm not sufficiently briefed in QT to ascertain if this should be the case, but it does seem from my limited knowledge that it would be.
So, if QT is 'right' can God exist? Or does He simply not observe anything? Perhaps this is the nail in the coffin of an All-PKG God?
It's a very interesting question, Leo.
Collapse of the particle waveform via observation is only one of the many Quantum interpretations, albeit the most popular one - the Copenhagen interpretation.
However, a new interpretation concerning Decoherence has been gaining popularity, which effectively removes the need for an observer. The basic principle behind Decoherence is that once a particle interacts with it's surroundings in a thermodynamically irreversible way, the waveform, for all intents and purposes, effectively appears to have collapsed. In short, it replaces the role of the observer with that of the wavefunction's surroundings, making the need for an observer redundant.
However - in QT, there are much more perplexing problems to deal with than just the Observer effect. In particular, there's a thought experiment designed by Einstein, Podolsky and Rosen -
the EPR Paradox, which was originally designed to show that there must be a gap in our knowledge of QT. It's a fascinating read.
Unfortunately (For Einstein et al), the actual experimental results support the Paradox, a result that gave rise to Einstein stating his belief that "God does not play dice with the universe" (and the eloquent rebuttal of "Einstein, stop telling God what to do" by Niels Bohr)
In layman's terms, the Paradox implies the following:
1. Information is being transferred between two entangled particles at faster than the speed of light.
2. A mechanism is in place that ensures, over time, that the correct number of matching particles is recorded
for the entire system - a Cosmic Auditor, if you will.
In short Leo - I think that currently QT actually tips the scales in the favour of a Cosmic Auditor / Intelligent Designer, rather than the other way around.
As you'll know - I'm a quantum skeptic. I believe that Einstein was correct and that Bell's theorem is flawed. If I wasn't - then I'd have to seriously consider believing in an Intelligent Designer.
