Nuclear georeactor origin of oceanic basalt 3He/4He, evidence, and implicationsNuclear georeactor numerical simulation results and the observed high 3He/4He ratios measured in Icelandic and Hawaiian oceanic basalts indicate that the demise of the georeactor is approaching, but the time is not yet precisely determined. As the georeactor dies, the geomagnetic field that it presumably powers after a time will begin to collapse. But unlike previous geomagnetic collapses, that have restarted and re-energized the field, a time will come when the actinide fuel of the georeactor is too diminished to initiate self-sustaining neutron-induced chain reactions; the georeactor will die and sometime thereafter the geomagnetic field will die and will not restart. At some point in time after the georeactor dies, there will be no geomagnetic field and life on Earth will never be the same. The challenge now is to determine precisely the time of georeactor demise. Within the present level of uncertainty, one cannot say whether that time will come in the next century, in the next millennium, in a million years, or in a billion years. But one thing is certain: georeactor demise will occur.

The theory of a nuclear reator at earth's core has problems, the chief one being the random reversal of the magnetic poles. A reactor would be expotentially declining but during magnetic reversal events we see, in the fossil record, a weakening field(it's declined some 10% in the last 150 years or so)seems to indicate fluid dynamo currents in the outer core as the B dot origin. It may continue to weaken then suddenly REVERSE(N=S, S=N), or, as the fossil record shows, return to the initial orientation. The offset fields of Uranus and Neptune also indicate a fluid flow origin for planetary magnetic fields, not a central core origin. Also, from diamond cell/ high pressure studies, it would seem that the inner core is made of hexagonal iron crystals and does not generally participate in the earth's overall magnetic field.
