Logic and causality??? Hi, what implications does quantum physics have on the realm of causality? For instance, due to the wave-particle duality, is it reasonable to say that the universe can be explained through causality? How does this change the concept of 'logic'? Intuitively, we believe that one thing causes another, no matter how complex or convoluted a system is. But with quantum physics, to what extent does the causal/logical model of the universe break down? I can't decide what to believe, maybe human language itself cannot explain what is going on.
