  •  Having scoured the Giant Impact hypothesis... (1+ / 0-)

    I must ask: IF THE MOON WASN'T THERE YET, and the impacting body was 'merging' with the earth (both per the hypothesis), then where are the OTHER two bodies in this imaginary three-body scenario?  The ones that would extra-hypothetically take molten ejecta past the rapidly-accreting debris disk, out of Earth's gravity well entirely - and give it enough of a push to let the now-frozen ejecta coast uphill an extra 141 million miles?

    Entities start multiplying so early in the GI hypothesis itself that  William of Occam would've blown his brains out long before he'd've arrived at the 'little Earth rock that could'.  It's not that I don't have enough imagination - I just understand its limits. OTOH, Rube Goldberg would have had a field-day w/ the magic mantle-piece.

    Sorry if any of this sounds grumpy.  NOT a good day so far.

    This year, I'm doing something I've never done before - I'm voting a straight Democratic ticket

    •  sun & earth are the 2 bodies (0+ / 0-)

      Then comes the impacting body or the ejecta which can be treated as the 3rd body. For the interactions of more bodies, you need to get out a good computer program.

      Google "3 body problems". The bodies don't have to collide.

      look for my eSci diary series Thursday evening.
