    Don't, for heaven's sake, be afraid of talking nonsense! But you must pay attention to your nonsense.
    --L. Wittgenstein

    So when Nature tells you that your nonsense is wrong, try a nonsense that isn't contradicted.

    Hello not_Fritz,

    that's a very interesting model of the PNs getting started. It may help to understand the forms even of the young PNs, we are observing: the clumps (condensations), the cyllindrical shells, and the outer envelops.
    Bookmarked.

    Best,

    JG
