Dust in the Greenland Ice Cores
Let me quote directly from http://saturniancosmology.org/moses.php as follows.."Velikovsky proposed that Venus approached Earth from the Sun side, and thus Earth at first intercepted the cometary tail of Venus. Actually, Venus likely caught up with Earth, with Venus moving somewhat faster than Earth because Venus was on an inner orbit. The edges of the plasma tail would certainly have 'touched' the Earth's plasmasphere and transferred electrical charges and gas ions constituting the boundary layers of the plasmaspheres."
Let me add that these gas ions would not substantially effect the Earth's atmosphere, since this would only have been a transfer between the double layers of two plasmaspheres. The sudden new value of an electric field between Venus and Earth, when they sensed each other, would have de-ionized many of the gas ions in the double layers of both planets."The initial contact of the plasmaspheres might have resulted in severe changes in the weather. Storms and hurricanes could have been a fact, and, as a result, Egypt would have been blanketed with dust, not from Venus, but from the Sahara."
"I disagree with Velikovsky's proposed makeup of the tail of Venus. He assumes a composition of fine ferrous dust at the far end of the tail, larger particles closer in toward Venus, and then hot cinders and rocks in the tail portion closest to Venus. Although I will concede the presence of dust or hydrogen and methane gases (which he identifies with petroleum), the tail of Venus was a plasma -- composed of electrons, protons, and ionized atoms (likely of methane). It is not likely that the plasma tail would be composed of a hail of hot stones, despite the fact that the surface of Venus was at that time still incandescent. It is more likely that the grit and hot rocks were generated from the Earth's surface when the arc from Venus traveled over land surfaces and explosively launched dust, cinders, and rocks into the atmosphere. [note 11]"
Note 11 reads..."Velikovskian investigators have always assumed that the "fallen sky," which, from various sources, lasted 20 or 40 years, was made up of dust from the tail of Venus. Thus there was some disappointment among Velikovskians that no record of "dust" was found in the Greenland ice cores at a location corresponding to 1500 BC. As I have stated, there was no dust in the tail of Venus, and, as others also maintain, dust would, at any rate, have settled out in a few months."
The "fallen skies" were due -- most likely -- to nanometer sized dust in the stratosphere -- which will stay in suspension, especially since it forms a canopy which blocks sunlight. The dust particles are the result of continental sized forest and prairy fires from the arcs of Venus (which arc is recounted in Exodus).
It does not rain out. It doesn't rain at the stratosphere. Conservative estimates today are certain that even a limited nuclear war -- burning down a dozen cities -- would block sunlight for a decade. And I'll maintain that nanometer sized dust, even if it ended up in ice cores, could not be found (no-one has looked) or even seen. If icecores are to be investigated, they would have to be inspected for the time period 40 to a hundred years after 1492 BC."This is not to say that the whole of the ice core data is not muddled by many unjustified assumptions about formation of the Greenland glacier. Volcanic dust from the Santorini explosion of ca 1350 BC was at one time held to be detected, but this was later repudiated. The lack of funds has also greatly limited study."
The point again is, that, if the tail of Venus is understood as the shadow of a coma enclosed by a plasma double layer, the whole of the arguments about icecores disappears.
