    Nor am I.
    But it is every member's duty in the sciences to correct errors where they see them.
    I agree, let's move on.

    Yep. If it were hollow and out were on the inside, as you suggested in post 4.

    But Radii's suggestion in post 12 - which is mostly what has been getting discussed - was about being on the outside. So there is no floor to stand on, only a "vertical" wall to cling to.



    Wait, what? It has a revolution of a little less than 8 hours. How does that relate to our "system"? What system?

    I was referring to the rotation rate, length of day, ~ 10 hours of most of the planetary mass, (jupiter, saturn ( even earth, if you take the angular momentum of the moon inward) ). a long shot, but closer to anything else.

    This is numerology.
    1. Find two unrelated things you want to relate.
    2. Cherry pick some traits that come close-ish.
    3. For ones that don't come close-ish, full-nelson them until they bend to your will.
    4. Ignore any that don't fit at all.
    5. Attach significance to the result, as if it has some meaning.

    Nebel does not have the foggiest, but lists numbing number co - incidences.
    The 5 minute light minute multiples in planetary orbit diameter,
    The ~ 27 day coinciding of Solar, Moon rotation and our reproductive rithm.
    The cancelling of the Jupiter & Saturn rotation speeds and their orbital velocities.

    Yup.

    Wasn't it von Daniken that claimed the Statue of Liberty is an alien artifact? His proof was that the height of the SoL in furlongs was equal to the distance to A. Centuari in parsecs, minus the number of leap years since it was erected.

    You can make numbers do anything you want, as long as you include enough of them.


    Numerology is number 14 on the Periodic Table of Irrational Nonsense.

    You are taking liberties with the grade of numerology I presented, they are written in real ratios. There are comforting coincidences though: The Earth orbit diameter is ~ 1000 light seconds ~2AU The weight of the atmosphere is equal to ~ 10 meter of water.

    Maybe the mods will separate out the numerology from this thread and move it to pseudoscience.

    This is ridiculous but the most ridiculous of all is to claim that the human menstrual cycle is fundamental to the solar system.

    not fundamental but seemingly in lock step with the rotation of almost all the mass in our neighbourhood. There is more to rhythms , than we might know now.

    Why is the same not true of hamsters, then?

    very good question, because in science , often deeper understanding comes from discovering where the theory diverges from the ideal., and that could lead into different disciplines.

    relating to the OP, the sliver from interstellar space, if for some reason the new arrival has retained, or ever had the spin rate of its home system (unlikeely), we could conclude that their main planets' day is ~25 % shorter than ours.

    What an irrelevant response.

    No, we couldn't.
    There are untold numbers of small bodies in our system, with a very wide range of rotation periods. If one of those ended up in another system, scientists there would be quite foolish to use it to conclude the rotation rate of anything in our system.

    An article on CBC concluded that the tumbler is like a piece of driftwood arriving with the tides. Being able to study some of that mechanism would give us great insights.
