51. Magnetism and Axial Tilts [Books] [de Grazia books]
... may only end in some kind of an electric current which may be running through the core of the Earth at about the geographical spinning equator, very roughly perpendicular to the geophysical poles. It is important, too, to appreciate that these two features, the magnetic electric current and the geographical spinning equator may be largely independent of one another ... be obtained one way or another by atmospheric testing of the field; any number of reversals (or none at all) might have occurred without leaving discernible evidence. The geophysicist, however, can search for evidence of the magnetic field in rocks . Igneous rocks have often been imprinted with magnetism when in a molten state; ...
52. On Morrison: Some Further Remarks [Journals] [Kronos]
... this heat (the greenhouse effect) and cannot be due to a massive heat flux from the interior as Velikovsky continues to claim." Morrison seems to assume that the geophysical principle of isostasy is inoperative on Venus - that the Earth's "sister planet" has grown a unified crust that acts as a global raft to support locally anomalous burdens ... insulating properties of Venus' atmosphere. He also finds it advantageous to limit the temperature of the interior of Venus, 3000 years ago, to 2000 K, whereas most geophysicists would permit the Earth even today, perhaps billions of years after its formation, interior temperatures twice 2000 K. In any case, however, Morrison finds that in ...
53. The Ten Points Of Sagan [Journals] [Kronos]
... floods?" The evidence was cited by me on 300 pages of Earth in Upheaval, a book the reading of which is indispensable for the discussion of this and other geophysical problems raised by my work. Omitting purposely any reference to all literary heritage of ancient civilizations, Earth in Upheaval brings geological and paleontological evidence from all parts of the ... "There is no sign in rock magnetization of terrestrial rocks ever having been subjected to such strong field strengths." In this Sagan errs: The problem that vexes the geophysicists is exactly this- how to explain the remanent magnetism of terrestrial rocks and lavas which is in great excess of what the global magnetism could have imparted in them when they ...
54. Radiocarbon Dating The Extinction [Journals] [Velikovskian]
... be considered as extremely important with respect to radiocarbon's message is that it should not conflict with all the other evidence regarding mammoths living in the far north, or with other geophysical evidence to be truly valid. But it clashes with this other evidence in no uncertain terms. If the date for the extinction is truly 10,000 to 12 ... Geological Survey in their "Absolute Dating and the History of Man." "Our crying need for absolute dating of geologic events of materials has spurred such massive efforts by geophysicists during the past two decades that the activity along the path has raised, on the one hand, a host of geologic believers whose hope and faith are so frenetic ...
55. The Electric Universe [Journals] [SIS Review]
... , Winter 1974-5, pp. 27-39. 42. E. Asphaug,'... the images of Mathilde reveal some surprises and provoke an overdue reevaluation of asteroid geophysics. Mathilde has survived blow upon blow with almost farcical impunity, accommodating five great craters with diameters from 3/4 to 5/4 the asteroid's mean radius, ... Kristian Birkeland experimented with electrical models of the Earth's aurora and showed that it must have a connection to the sun. His early death unfortunately allowed the views of the influential geophysicist, Sydney Chapman, to dominate. Chapman proposed an isolated Earth in which the ionospheric currents were self-contained. After the discovery of the Van Allen radiation belts and a ...
56. The Empire Strikes Back [Books] [de Grazia books]
... letter disputing this evidence (provided this letter is not more abusive that Mr. Margolis' criticisms). If Dr. Velikovsky can suggest a recognized authority in astrophysics or geophysics willing to discuss his theory as a whole in the light of recent verification of some of his predictions, I would consider giving space in the Bulletin for a brief ... names of Menzel and Shapley because I remembered that they did analyze Velikovsky's theories at the time of their publication. I would be glad to have any other recognized astrophysicist or geophysicist (including the Princeton and Columbia astronomers who have pointed out in Science the correctness of some of Dr. Velikovsky's specific predictions), to present in the Bulletin briefly ...
57. Thrusting and Orogeny [Books] [de Grazia books]
... , they are not made of sediments, they are not folded and they have not been compressed [8 ]. The last sentence points up an impossible predicament for conventional geophysics: a supposed situation in which the continental crust folds and thrusts and compresses into abundant mountains while the oceanic crust slides up and under and around without making mountains, ... , as we said, continental drifting is called thrusting. The seabeds are flat, save for the steep oceanic ridges, the great rises, and the innumerable seamounts. Geophysicist Edward Bullard marks the contrast: The mountains of the oceans are nothing like the Alps or the Rockies, which are largely built from folded sediments. There is a ...
58. Uniformitarian Or Catastrophist? Ice Age Theory [Journals] [Velikovskian]
... leading to understanding of this phenomenon, has led to chaos, just as with the cause of the Pleistocene extinction. The tool of mythology which Velikovsky employed along with the geophysical evidence, clearly explains these phenomena in clear and rather coherent terms. His approach surely deserves a better appraisal than that furnished by hostile groups unalterably opposed to his thesis ... by cool water). Currently, the average June-to-September temperature is about 10 C. (Loewe, (1971), loc. cit.] According to estimates by geophysicists, Hudson Bay likely was non-existent between ice ages (if there was more than one) due to isostatic rebound. [Ibid., p. 333] Isostatic ...
59. Henry H. Bauer and Immanuel Velikovsky [Books]
... point because, in that section of his book, Corliss cites several scientists who say essentially the same thing. (69) Irwin I. Shapiro, a professor of geophysics and physics at M.I .T . states with respect to Venus' retrograde rotation that the possibility has been presented. "Venus once collided with an asteroid ... comparing the densities of the terrestrial planets we were able to cite Cattermole above, who claimed "Mercury is by way an exception" to this concept. In addition, geophysicist T. F. Gaskell had also reached the conclusion that the densities of the terrestrial planets are much too different to be accounted for by dust- cloud condensation and ...
60. Ice Core Evidence [Journals] [Velikovskian]
... in comparatively recent geologic time.(9 ) The only reason for rejecting this hypothesis is the catastrophic requirement inherent in lowering these canyons deep below the oceans. Using straightforward geophysical evidence, Johnson then showed how neither turbidity currents, nor land slides, nor submarine spring sapping can account for the creation of these remarkable sea canyons.(10 ... .
