Point is, that the source and composition of the lunar dust is well known. We can even duplicate it here on earth. There isn't anything magic about dust that consists of a combination of microspheres and hook ended fractured rocks. Put that in a highly charged environment, and no strange and incomprehensible theories are needed to explain why it sticks to things. It's shape, size, and static...... And now for Art. Art, the dust in not specifically something that is roaming around the universe in packs. The dust or lunar soil is composed of fractured and spheroidal minerals mixed in with meteoriodal material from the little buggers that hit the moon and formed those fragements. The reason that there is a lot of that stuff on the moon as compared to the earth is because metoroids hit the moon with regularity, and once formed, tend to stay there. On earth only the larger meteoroids make it to the surface (yeah, I know a meteoroid is one that makes it to the surface) and once there, they become assimilated, and are hard to find. Occam's razor isn't always correct, but in this case..... - 73 de Mike KB3EIA - |

It is believed that in prehistoric times,
an ice comet collided with the earth with so much force at a spot near the Yucatan Peninsula, that a chunk was dislodged and hurled into orbit. This collected and compacted becoming the earth`s moon. I think you will find that the Earth had two moons, and the one in a decaying orbit hit the Earth - creating the (now burried) crater, as well as leavin us with a somewhat thinner crust. The bit of green cheeze out there, over our heads, is as old as the "inner Earth", but like the Earth, it is steadily growing as more space debris arrives. If a comet had struck the Earth, then just the sheer momentum would have destroyed it, if it had been big enough to hurl something out of the Earths gravity. Even the Manson comet was not that big, and look at the size of that crater ;-) But back to space dust - Fred Hoyle (a well-know scientist from Yorkshire, England) pointed out that we all have noses with the holes underneath so that our air-intake is sheltered from the debris and diseases that are falling from space. Fred also invented the term "Big Bang", although he meant it sarcastically, in true Yorkshire fashion. (Eeeeeeee bah gum! The's nowt as odd as fowk!) |

If you guys want to read hard science without any mathematical
equations, read ATOM by Larry Krause... This is as close as you can get to understanding cosmology without having to take a PhD in physics at the university... If you read this and take the time to think and understand what he is sayiing I 'garontee' you will see the world in a whole new way... denny - an old farm boy who never wondered about the ability of cow **** to stick to your shoes... and "Two quarks for Muster Mark" |

The bit of green cheeze out there, over our heads, is as old as the "inner Earth", but like the Earth, it is steadily growing as more space debris arrives. As I understand it, the current "mainstream" thinking is that there were numerous collision events, of greatly different magnitudes, and very far apart in time. It's now believed that quite early in the lifetime of the solar system, when the planets were accreting out of a large dust-ring around the young Sun, a planetoid of roughly the size of Mars collided with the proto-Earth, striking a glancing blow. This impact shattered the smaller body and did really serious damage to the larger (probably re-melting much of it) and threw a lot of material back up into orbit around the (now-larger) Earth. Much of this material eventually fell back to the surface, some escaped entirely, and most of the rest eventually formed the moon. This event occurred quite a few billions of years ago. The impact at what is now Chicxulub in the Yucatan was a lot more recent (65 million years ago) and involved a much smaller body (perhaps 10 miles across). Current mainstream thinking is that this impact was probably the coup de grace for most of the dinosaurs... it was one of the largest impacts in the history of Earth, but there are geologic records of earlier impacts that left larger craters (the Vredefort and Sudbury structures). -- Dave Platt AE6EO Friends of Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

While the geologic record for Chicxulub is well documented the
commonly known "fact" that this caused the dinosaurs to die out is debatable since their demise was spread over millions years covering both pre and post Chicxulub impact; not just over a few weeks or months, or even a few hundred years.. The seabed record does show Chicxulub caused a drop in temperatures for some time period and significant species losses.. There have been a number of other massives die offs seen in the fossil records that are not well explained and not all can be tied to an impact... The other issues you point out, such as the genesis of the earth's moon coming by impact from an extra solar body is the currently accepted theory of mainstream cosmologists, less a maverick or two... denny |

Oh, I agree... that's why I used the phrase "coup de grace" and "most of the dinosaurs". There's good evidence that there was a lot of ecological stress from other causes (e.g. volcanism, change in ocean circulation patterns, etc.) which had been reducing the diversity and population of many Dinosauria for quite some time before the Chicxulub impact. And, of course, mainstream scientists now believe that one branch of the Dinosauria survived right up until present times. The seabed record does show Chicxulub caused a drop in temperatures for some time period and significant species losses.. I've seen one report which indicates that the area in which this asteroid hit consisted of rock which was unusually rich in sulphur, thus leading to a more severe sulphate-particle "nuclear winter" effect than what might have occurred if the impact had been elsewhere. One way or the other, it was probably a rather rotten time to be on this particular planet. There have been a number of other massives die offs seen in the fossil records that are not well explained and not all can be tied to an impact... Agreed. Life, and death, are both rather complex matters :-) -- Dave Platt AE6EO Friends of Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

As an aside, what has this got to do with the focus (eg. antennas) of this forum? Did the moderators kick you out of eHam? Every thing! They are static particles that rest on diamagnetic materials used for antennas. These particular lunar particle coverings was predicted more than a hundred years ago by the masters which is before radio was even thought of . I would have thought that the subject of antennas would fit right in here! Well Arthur, Some several silent days have passed on this subject that is going nowhere - it seems to mimic your forced retirement at eHam (or are both due to the wholesale lack of interest?). However, in keeping some semblance of a technical discussion on antennas (I have to review just which group this is), then some technical enquiry is in order (which I admit has a slim prospect of any coherent answer). So, does the a.) absence b.) presence of lunar particle coverings on my antenna c.) improve DX d.) exclude DX 5.) does not matter To repeat a message that hinged on the outcome of the Battle of the Coral Sea: "The World Wonders." 73's Richard Clark, KB7QHC |
