I started a thread with the above title in the Physics & math Forum. Perhaps those who post here and seldom (or never) read or post in that forum might be interested in the topic. I hope that this will be the only post here.
I assume it's impossible to say unless you know whether a deterministic cause underlies quantum randomness. I sort of hope that the answer is 'yes' because (and it's unscientific - I know) I just like the idea of the universe running according to nice neat cause and effect relationships.
Laika: There is nothing unscientific about causality. Causality is inherent in all things. Quantum Mechanics, though it may be beyond our capacity to forever understand all the hidden variables, due to the nature of observation on that level, still presumably exists in a deterministic system. Things simply do not "act on their own".
Prince_James, you misunderstood me. What's unscientific is my preference of one scenario over another. I do tend to agree with you about an underlying deterministic system. But since the quantum world is so utterly bizarre to our macroscopically-biased understanding, I wouldn't be at all surprised if it turned out that at this level things simply do "act on their own".
