Hector: If a tree falls in the woods and no one is around to hear it, does it really make a sound?
Petra: I never understood that question.
Petra: If the tree falls, it creates sound waves. If no one is around to hear it, the physics of the event does not change. I just don't get why this is considered a recondite philosophical question.
Hector: Well, if we examine the same question at the particle level with quantum physics, it could be argued that the answer is indeterminate or chaotic, due to the Heisenberg uncertainty principle.
Petra: Why can't you ever take my side?
