Thanks for sharing this. I was vaguely aware of this explanation – I believe I watched a Richard Feynman video where he describes this.

The funny thing is that while the standard quantum explanation for this behavior is different than the situation I described in my post, it’s somehow even less intuitive than believing that the light “knew“ where to go before it left it’s source. Instead we are supposed to assume that it checked all possible directions and instantaneously made a (“correct”) decision.

I am fully aware that my sentences above are full of anthropomorphisms and are hopelessly classical. But in my classically oriented mind, my first way of describing the situation and you’re more correct way both involve a violation of what I would consider “causality”.
