If you look at this film backwards, you will see a particle coming from infinity and hitting a two body system at just the right energy to get integrated in it.The problem I see with this idea, is that I could watch the third body zip past the other two bodies with a deflection, and I could say "what are the odds! That's just exactly the right deflection to start forming the "w" on "watchamadoodle". Intuitively what you said makes sense, but it reminds me of the argument for God where people say "what are the odds!"
You'd see that and say: what are the odds!
That's really interesting on the QM interpretations. I don't understand the details, but it seems the copenhagen interpetation might have an advantage by mirroring the way that thermodynamics distinguishes past and future?
