Double slits from the particles viewpoint

    How would two rapidly approaching slits appear to a particle? Would they appear fuzzy or even indistinguishable?

    The particle has no point of view, so there's no meaningful answer to that question.

    We could ask what a person approaching the barrier with the slits sees, or what a photograph taken by a camera would look like. The answer is exactly what you'd expect: a barrier with two slits in it.

    Actually, I think there is a more basic problem to Jilang's question. He is viewing the particle as having a path. There is no path. There is a place where the particle is detected. If the which way information is not captured, it never existed.
