    Quantum physics gets weirder all the time.

    Not good reporting.

    This is a side step, but quantum physics isn't super confusing if your foundational base is not determinism.

    Still, it expands the idea of superposition into a more macro realm.

    Does it? I figure that if my dog is here, she isn't somewhere else. Sub-atomic reality won't change that.

    Is your dog so tiny that you can notice quantum effects with your dog?

    All my dogs were sentient. That what you mean?

    No. The idea that something doesn't exist without conscious mind observing it is just an old superfluous erroneous nonsense metaphysical interpretation of quantum physics that, contrary to popular belief, isn't part quantum physics itself.

    if you want a better idea what I am talking about)

    Quantum effects become progressively more difficult as you try and observe them at larger and larger scales as a whole until they become impossible to observe on the scale of, say, the size of a typical whole dog. That is why your dog must be tiny (just a few cubic nanometers max) for there to be a credible chance for you to observe them in your dog as a whole.

    I do know about the von neumann thing, why the view exists and why it is wrong.

    At the level of a dog, we don't see quantum effects. That doesn't mean they aren't there. Signal/noise thing, may be?

    I'd meant to comment on this before - I love the title to this thread - not quite the right number of syllables for a Haiku, but I think that's allowed in English language ones.
