Lopsided Earth Core
The May 2010 edition of Science carried several articles expounding hypotheses to explain the lopsidedness of the solid ‘iron’ core of the Earth. As one might expect, the solid core is anisotropic, i.e. having different characteristics along the north-south, or spin axis direction, versus parallel to the equator. However, the new lopsidedness under discussion concerns what the authors of one paper describe as “a prominent feature of the Earth’s core”, a measurable difference in its Eastern and Western hemispheres.
This difference is inferred by studying the velocity and attenuation of waves generated by earthquakes at a number of seismic stations around the world. In keeping with the uniformitarian paradigm, geophysicists feel impelled to devise a steady-state explanation, i.e. some process that has been on-going for at least millions of years. Monnereau et al. hypothesize that the asymmetry “implies an eastward drift of the [solid iron] core material, driven by crystallization in the Western Hemisphere and melting in the Eastern Hemisphere”.
In this model the ‘grains’ of iron in the core, grow in size from tens of meters to hundreds of meters as they move slowly from West to East. They infer the size, and thus the relative ages of the grains by their scattering of seismic waves. The interesting aspect of this hypothesis is that the older, translated grains, are exposed in the Eastern Hemisphere by melting of the top layer of the solid core. Since the current data amount to a mere snapshot of the process they are not able to determine the time scale of this translation, suggesting that it takes 100 million years up to a billion years. Of course the core has grown throughout this period.
Cyclic Catastrophism
The CC scenario, observed and reported upon by one hundred generations of mankind, suggests that the melting of the outer layer of the inner core occurred during the Vedic Period (3700 to 700 BC) due to one hundred extended encounters with the planet priori-Mars (Mars and Mercury, its ancient core) during each of which it remained in a geostationary orbit directly above Mt. Kailas in Tibet for fifteen years at a time. The tidal force of this huge body, only 44,000 km (center to center) from the Earth caused extensive sub-surface melting of rock in the Eastern Hemisphere, as evidenced by the layer of molten rock still present just below the surface of Tibet (which remains unexplained by geophysicists to this day). This same subsurface melting extended to great depths, accounting for the melting of the outer layer of the solid core of the Earth, thereby exposing the larger, older grains in the Eastern Hemisphere of the core, without the need for the complex, unexplained transport of material within the core. Since this force was removed only 2,700 years ago, but a moment in geologic time, its effects would certainly still be present.
For all you aspiring astrophysicists who have not been exposed to Cyclic Catastrophism, who are just salivating to explain that a geostationary orbit above Mt. Kailas, at 30 degrees north latitude, is impossible, let me add that the spin axis of the outer rigid shell of the Earth shifted to Hudson Bay during each encounter, bringing Tibet to a temporary ‘equator’ and also accounting for the enormous North American glaciation centered there.
