... C & C Workshop 1988:1 , pp. 32-36) although, as Alasdair Beal has pointed out (see C & C Workshop 1990:2 , pp. 20-23), these contain errors and have since been modified. Despite being strongly critical of the uniformitarian approach of orthodox scientists, he happily quotes Cook's simplistic extrapolation from current radiocarbon trends to claim that the atmosphere may be only 10,000 years old, even though just about everyone agrees that the atmospheric radiocarbon content must have fluctuated considerably. He mentions a 1979 paper which claimed that the oldest known rocks contain fossils of complex cells, but ignores the 1981 papers which cast considerable doubt on these conclusions. He ...
162. Epilogue: Questions And Answers (Ramses II and his Time) [Velikovsky]
... chronological placement of the strata. Scarabs, often carrying royal Egyptian names, are second only to pottery (usually sherds) as arbiters of age. What is then the verdict coming from pottery and scarabs in the court where conventional chronology and the revised scheme of it stand before the bar? 7. And what is the verdict coming from radiocarbon laboratories? I gave the story in short in the Introduction to my Peoples of the Sea. In Pensée VI, Winter 1973-74, pp. 5ff., I published a collection of letters spanning two decades, detailing my efforts to obtain radiocarbon tests of materials dating from the Egyptian New Kingdom. The single test which I succeeded in ...
163. The Velikovsky Affair [Books] [de Grazia books]
... to publication of his work. He reasonably claimed to have performed all tests within his power (the historical tests) but sought other tests requiring the use of equipment that he did not have access to. For instance, over a ten-year period he corresponded with several institutions - universities, museums, laboratories - trying to persuade someone to perform radiocarbon tests on Egyptian artifacts of the New Kingdom, without success. He also sought unsuccessfully to have the spectrogram of Venus analysed for heavy molecules of hydrocarbon. One wonders here, as in the case of other folk heroes, ' whether a condition of accepting with grave seriousness the rationalistic doctrine is to be innocent of experience of the world ...

... found 5 kilometres deep on the floor of the Atlantic Ocean'. Uranium-Thorium Dating Tool sources: Nature 345, p. 405; New Scientist 16.6 .90, p. 30; Daily Telegraph 11.8 .90; Sunday Correspondent 12.8 .90 New uranium-thorium dating of corals in Barbados gives consistently older dates than radiocarbon. The uranium-thorium dates agree with dendrochronological dates for the last 11,000 years, so are preferred. The amount of 14C in the oceans would appear to have varied by as much as 40% over the last 30,000 years. Lost Mummy Found?source: The Observer 20.5 .90, p. 4 ...
165. The Velikovsky Archive [Journals] [Aeon]
... presentations as well as Velikovsky's own replies. Some of this material was published in a special issue of KRONOS, [19] but much more exists in archival boxes that, unfortunately, remain inaccessible to researchers. Ash was Velikovsky's title for the correspondence documenting his effort at getting samples of Egyptian New Kingdom artifacts dated through the utilization of the radiocarbon method. Much of this correspondence was published in Pensée, [20] and is also available as part of the online archive. [21] Had it been published as a book, the Ash correspondence was to have been accompanied by discussions of the radiocarbon method, such as "The Pitfalls of Radiocarbon Dating," [22 ...

... event, such as cultural decadence, invasion by outside barbarians, internal conflicts, domino' collapse, over-centralization of authority, economic collapse, drought-induced famine, volcanic eruptions or widespread earthquakes. Only the last two come anywhere near Velikovsky's prime thesis of multiple near-collisions by an errant comet. Nevertheless, in an Appendix James refers to the inconsistencies of radiocarbon dating in the middle of the first millennium BC. Carbon-14 is formed continuously in the Earth's upper atmosphere by the action of cosmic rays on nitrogen, and in dead tissue constantly changes back into nitrogen by the emission of an electron. Unfortunately the amount of Carbon-14 in the atmosphere fluctuated greatly in the past, at times falling and then ...
167. Pole-Shift [Journals] [Catastrophism & Ancient History]
... Hapgood showed that the theory of continental drift (or "seafloor spreading"), as now presented to the public, gives rise to insoluble problems which can be resolved only by the assumption that shifts of the outer shell have occurred. In his book he detailed how such shifts could cause continental drift. By making use of thousands of radiocarbon datings of climatic events of the last 100,000 years, Hapgood demonstrated that the earth's outer shell has slipped over its interior- changing the relative positions of the poles- three times during that period. The last such change came at the end of the last ice age, about ten thousand years ago. A very simplified explanation ...

... more careful examination of texts referring to calendars, festivals, Venus and Sirius, in order to ascertain which of these two celestial objects (perhaps both) the Egyptians were really interested in, and how well the accepted astronomical chronology stands up to the test of further research." Following Professor Roy, DR EUAN MACKIE presented a paper on Radiocarbon Dating and Egyptian Chronology. In this, after an introduction to the theory and practice of radiocarbon dating, he presented the results of tests undertaken on materials from the 19th, 20th and 30th Dynasties during a research programme conducted over the last few years aimed specifically at short-lived samples from historically dated strata, with the purpose of achieving a ...
169. Pole Shifts And The Arctic Ocean Ice Cover [Journals] [Velikovskian]
... and glaciers of the northern and southern hemispheres grew larger the oceans fell 30 or so feet and exposed the submerged shores and the mollusks that inhabited these shores. The problem with Carbon 14 dating mollusks is that both fresh water and marine forms can obtain incorrect dates from the water lacking C 14 and giving dates which are too old.125 Radiocarbon in oceans is found in the mixing zones between the upper warmer and deeper cooler water layers, which show significant differences in carbon dioxide content. The older the specimen, under these conditions the greater the age of the mollusks appears as opposed to its true age.126 To make matters worse, shells taken from a burial mound gave ...
170. Ice Core Evidence [Journals] [Velikovskian]
... ! Yet Ellenberger and Mewhinney suggest that such a record can clearly disprove Velikovsky's hypothesis. With 70% of the volcanic acid signal correlation missing during Velikovsky's catastrophic timeframe, very little is secure and the evidence touted by Ellenberger and Mewhinney proves either extremely inconclusive or without real merit. For example, Hapgood presented a list of glacial eruptions based on radiocarbon dates in The Path of the Pole.(46) Here is an abbreviated sample: Date (Years) Place 8,620 +- 350 Japan 11,520 +- 400 Japan 11,720 +- 220 Japan 12,750 +- 350 Montana, United States 13,800 +- 300 Costa Rica It is ...
