Scott (Talk about not reading )Why I don't like our Moon ejected out
from the bowels of the Earth,you can read that I answered this in full on my post of 1/28/07 at 12.42pm " in depth". I "even read" by another astronomer that Moon"s lack of iron takes away the credibility of the Moon "once upon a time" being a chunk of the Earth. Scott where did the Moon's iron go. Iron is one of the most stable elements. Lots of iron found on top of the Earth's crust and in its crust. Very easy to dig up,and that proves even in its molted state not all the iron sank to its core. Please think of that when telling me all the iron was in the Earth's core when the Earth ejected out the Moon. Also why there is no known iron in the Moons core. Best you keep in your pea brain the Moon had to also be in a melting state. You can't answer this Scott because now you know your low wit has gotten you into trouble with known facts about the Moon. I would ask you to think about all this,but thinking is what parrot brains can't do. |

I would ask you to think about all this,but thinking is what parrot brains can't do. Okay, apparently you are even less clever than I gave you credit for. To whit: 1) What astronomer said this - sources please. I have given you those I quoted from. The least you can do is present the source so we can check the context of the statement. 2) There is ample evidence for iron in the makeup of the Moon - its core is likely iron based on average density compared to crust density (much like we do for the Earth) and the remnant magnetic field detected frozen in the crustal rocks, which is likely a fossil field from when the Moon rotated faster (before tidal breaking locked it into 1:1 synchronization) and its core was more molten than now (if it is even now partially molten). 3) Most computer simulations show the iron escavated from the surface of Earth fell back to it, leaving lighter material out of which to form the Moon. And in a previous post on this topic, I gave you a URL for seeing the results of some of those simulations. And as I made clear in my last post, no one claims ALL the iron making up the Earth had migrated to the core when the impactor hit Earth (and your statement above implies that the Moon was ejected by Earth without help, which is not what the collisonal-ejection model says). I said most of the iron. What iron made up the impactor also likely fell more toward the Earth than stayed in orbit after the impact, again, denying lots of iron to the Moon in its makeup. 4) So, we come to the conclusion that it is you that have your facts screwed up. The composition of the Moon is well know to me from the reference material I have here on my desk and is consistent with the collisional-ejection model at present. Even new data from Clementine and other recent missions are consistent with the model. As I have said all along, science is a harsh master, and has definitely dealt you a blow. You would be wise to learn some before you attempt to challenge it. Idle speculation is no match for the razor used in science to discriminate good from bad ideas. |

Dear Scott Miller. I can't remember the astronomer that also did not
like the Moon being hit by a Mars size object and that ejected out a large chunk from the Earth,and it went into orbit,and we call this large piece of the Earth the Moon;. This astronomer who's name I'll have to recall also pointed out that the 830lb of Moon Rock the Apollo astronauts brought back to Earth were not exactly like Earth rocks. I hope someone here will help me and let us know what these differences were? Best to keep in mind Jupiter has 61 Moons Uranus has 5 Moons that are even closer in orbit than our Moon so using the theory of ejection they all came out of Uranus.(being hit by a large object) Saturn has its Moons,and Titan is even larger that Mercury. That must have been a real big collision(oh ya) Hard to fit the theory in with Pluto I'll let you show how being hit created its Moon,Im sure you will make it fit. I'll leave out Jupiter 61 Moons,and you can work that in as well. Scott collision theory I do not like. capture theory fits in better for me. I know you do not like my ideas. but they are based on good science. Bert |

No one has said that the collisional ejection model is applicable to all satellite systems around all of the planets. It is applied to Earth because its system has a larger satellite/planet ratio in terms of diameter compared to other planets in the solar system. The only other higher such ratio is between Pluto and Charon. Most of the planetary systems with satellites (and Jupiter is up to 62 - I think I told you that once before) likely formed those from the original cloud of gas that formed the planet itself (mini solar systems of a sort) and/or later captured them (this explains many of the small outer satellites with retrograde orbits). Major difference between Moon rocks and Earth rocks is a lack of water in the crystaline structure of the rocks. There are slight differences in isotopic abundances, well within the limits expected and in some cases well explained by a high temperature event (such as the collisional ejection model). And, if you wish to see about how a collision might have been responsible for the satellite system of Pluto, visit the Hubble Space Telescope site and go to the HST images of its newly discovered satellites. The discoverers are the ones that have proposed the idea. Finally, your ideas are based on poor science. You have some inkling of an idea how you think science works, but each time you post a new message, it simply demonstrates that "an inkling" is being kind. |

Dear Scott Miller So using that theory on relative sizer Charon came
out of Pluto,and if the ratio in size is different you can use the capture theory(the one I like) Surely your joking Mr.Miller As I recall Moon rocks have a larger amount of an element that is extremely rare on Earth (need help to name that element?? ) You start your post by saying "There I* go again" I think my points are a good argument for capture over collision. Hitting two large objects together is messy,and to get get one to orbit around the other out of this explosion,is very,very bad thinking (science) Capture works easy,and is far more realistic It is in reality natures way You Scott Miller emphasis size and weight. Yet you forget size and weight objects accelerate at the same rate in a gravitational field Sorry your explanation is wrong and your lack of thinking is showing. Your virtual old time friend Bert |

In article .com,

Clueless AA - thats the first attack of the kook on the moon rocks. http://rst.gsfc.nasa.gov/Sect19/Sect19_6.html Chemically, the lunar rocks were mostly in a class by themselves, being different from their terrestrial rock type counterparts. They are deficient in iron, low in volatiles (including potassium and sodium), and are totally anhydrous (meaning that water was not present when they formed; water found on the Moon is discussed below); compared with Earth rocks, they were exceedingly fresh, showing almost no signs of alteration. As an example of their chemical specificity, examine this diagram which plots the ratio of potassium (K) to uranium (U) versus changing potassium content; note that both meteorites (chondrites and carbonaceous chondrites) and terrestrial igneous rocks plot in different areas of the diagram than the lunar rocks. However, the meteorite class Eucrites plots partly within the lunar samples field, suggesting that these are actually ejecta from the Moon that reached Earth. Perhaps a basic geology class is in order. -- Saucerheads - denying the blatantly obvious since 2000. |

Your virtual old time friend Bert How you do ramble. I have given you a scenario for the collisional-ejection model and included how it would vary the abundances of that material out of which the Moon eventually formed from that collisional material and you ignore that and play mind games. No, bert, capture does not work with a body as large as the Moon because such a body would have such a large kinetic energy relative to the capturing body (the Earth) as to be uncapturable by itself. There would have to be large body to transfer much of the energy to in order to reduce it to a level where Earth might capture it. Then, of course, you have to show the special circumstances necessary for the orbit obtained to be tilted with respect to the equatorial plane of the Earth. Specifically, the Moon would have had to come within 50,000 kilometers of the Earth's surface with exactly the right speed to leave its prior orbit around the Sun (hence the need for a body to transfer excess kinetic energy to), and done so without hitting our planet instead. So, if you think your points are good arguements for capture, you don't understand capture of a large body by another large body. You lose this game because I have too many references from too many people who have worked through this problem. As you haven't.... |
