The Cult of the Geodynamo
The geodynamo theory, as proposed to explain our Earth’s measured magnetic field, extrapolated over a globe, is an unobservable scientific model, that requires a level of religious faith to believe in.
The Curie point is the temperature at which a material loses its ferromagnetic properties. The temperature of the Earth’s outer core is theorized to be around 5500-5700 Kelvin, well above the Curie point of iron, which is around 770-910 Kelvin. Simply, the convection currents in the outer core, as proposed by the geodynamo model, should not have ferromagnetic properties, but it is believed that they do anyways.
The theory predicts that the magnetic field intensity at the surface of the Earth should be around 30-60 microteslas, yet measurements show it to be around 50-60 microteslas. The field polarity is also supposed to reverse every 250,000 years, but per the consensus paradigm of the greater scientific community, it has been roughly 780,000 years since the last reversal, for some unexplainable reason. Also, quite strangely, the field axis we measure isn’t even aligned with the reported rotation axis, as the theory predicts. It’s off by 11.5 degrees.
The geodynamo theory, and its attempts to explain the Earth’s magnetic field, is contrary to reason. At its core, it breaks the framework of the Einsteinian cosmos, unless you are willing to maintain a tenant of religious faith.
