The wavefunction is the same object shared by all universes, correct? Thus a point's spatial neighborhood in one universe is not the full neighborhood of the point. I would imagine (if it's a coherent notion) taking a derivate only "within one universe" would have a different result than taking it with the full wavefunction.
Wouldn't an air molecule already going one way need a separate cause to be going that way (as in something that pushes it that way (probably another air molecule))? And wouldn't that put it simply further in configuration space (ie make interference less likely)? I have still trouble imagining when interference happens and when not. You need a path in configuration space to connect two points to have interference? And if the distance is big there are more chances for the intervening configurations to spoil the interaction?
It seems the air gets scrambled. I guess any device that could detect the scrambling would be as good as detecting the particle directly?

I meant the universe's neighborhood, at taking the derivative of the universe's wavefunction at that point.
