    Indeed

    In the video , Ted talk , conclusion

    Out comes the moon , from the molten Earth .

    That's correct. But not the way your miscomprehension saw it. It evolved a giant Impact which you denied. Now you are playing hard to get and removing yourself from your original nonsense. I blame your poor and/or zero comprehension.
    All this TED talk was on, was a variable aspect of that Impact many eons ago, when Earth was still molten.
    It differs slightly from the accepted Impact theory, in that the accretion disk the Moon formed from, was actually still a part of the Earth, while the accepted version, has the accretion disk the Moon formed from, in an orbit around the Earth, from that same impact with Theia.

    The moon came from Earth . Period . In Sarahs' theory .

    The Moon came from the Earth in the already accepted giant impact theory with Theia also. Sarah's model is just a variation on that impact theory.
    But you are being dishonest river. That's not the point you are making...see your own opening post.
    So many mistaken points as already pointed out.
    When will you ever learn.

    as/re Sarah: don't forget the disclaimer in post #47
    the moon may have a veneer of earth shared material, but most likely has a core that is very much theia

    Sure, that certainly may be a possibility, but again the point of this shemozzle of debate [in the fringes no less] is river's usual tiring, automatic dismissal of accepted science, and then instead replaces it with his own nonsense.
    And if you believe I'm being too hard on him, let me point out that he has shown total ignorance in the OP, by claiming the Moon has a dark side, and doesn't rotate on its axis. Such rather basic errors would I believe, disqualify that person from making any other claim. River has made a choice to act like a troll...It was river's choice to have himself banned from the sciences, by his continuing and incessant anti mainstream diatribe.

    First how the Moon came about is a theory , nothing more .

    Second if the Moon came from outside our solar system , which to me is far more likely , then the Earth does not have the mass , gravity , to over ride the Moons own inertia .

    And assuming no direct collision occurs, what is the necessary mass of X needed to capture object Y coming from outside the system. It's your idea, so I'm guessing you're just making this all up without putting any actual thought into it. A link explaining it will suffice.

    For reference, the moon masses just over 1% that of Earth. Charon on the other hand masses about 12% of Pluto, and Pluto managed to get that moon into its orbit.

    To your last statement ;

    Then it isn't gravity that allowed Pluto to Capture Charon , is it .

    What do you suggest then? Magnets? Tractor beam? Butterfly net? Cowboy lasso? Parachute? Telekinesis?

    Anyway, it appears you don't have an answer to my question, which means you're just making it all up, and yes, without any actual thought involved.

    When you have calmed down , then think about what I said above , in this post . That should take at least 2-4 weeks .

    No, it just means that your idea that the relative mass between planet and captured body has no relevance to the capture.

    Captured Body Mass matters .

    And Not just the mass but the density of the mass ( and volume taken ) .

    Yep just like Newtonian gravity is also a theory.
    As usual, you know not what you are talking about.

    River never has an answer, except silly one liner statements of supposed unsupported claims.
    That's why he lingers and is confined to the fringes.
    Check out his "claims" in the OP, and the total ignorance that it reflects.

    Asking river for any link, supporting any of his nonsense, is like trying to pull Hen's teeth. It won't happen because nothing ever supports his nonsense.
    Good example of a captured moon. In fact the Pluto/Charon pair are also our best example of the future of the Earth/Moon system, with its total geosynchronous orbits about one another.

    pad , I'm sure that Halc is mature enough to think for their self , as we all are by now .

    Halc also is relatively new, and is probably not as aware as I am of the extent of your stupidity and trolling. Although obviously reading the ignorance shown in your OP, and your follow up trolling posts would be a clue.

    I'm sure that there are some that don't think I am stupid and nor a troll .
