The First Cause? Prime Mover Argument

[Alex K]

I don't think the dimensionality of space makes a big conceptual difference at that point. In copenhagen, the collapse doesn't mean that the wave function is gone, it is merely projected down to a new function which is zero except for those parameter values compatible with the result of the measurement. Experimental resolution plays an important role here, me no expert on the intricacies of that. But the randomness comes in where it is decided which possible measurement result of those that could come from the previous wave function, are actually realized.
