Gyroscope moment rotates Earth inner core vertically because of its unstable “egg” shape. The rest ellipsoidal part of the planet has opposite vertical motion. That is the polar shift. The Sun appears on the west. New angular velocity direction of the core and no homogeneous gravity field of the Sun cause acceleration of the core self-rotation with corresponding increasing of the Earth magnetic field, pushing the planet away from the Sun during millenniums. Sinus law of the core rotation makes significant jump in acceleration 6,500 years after causing new centrifugal redistribution of the planet water more concentrated around the equator area, followed by big earthquakes and volcano eruptions. It is a big flood. Planet with accelerating self-rotation of the inner core continues to leave sunny area approaching to the ice period. The shape of the core is ellipsoidal then, giving the chance to the “sunny” moment to rotate it vertically again 13,000 years after. The Sun appears on the east. It is another polar shift. New conditions cause mild slowing down of the core self-rotation pushing the planet toward the Sun. Magnetic field is slowly decreasing. 6,500 years after the same sinus law influences sharp decreasing of the angular velocity of the inner core. New redistribution of the planet water from the equator to the north and south appears, followed by big earthquakes and strong winds. It is famous big flood we “remember” it. The planet is approaching to the Sun losing angular velocity of its core and good shape for good stability. 6,500 new years and new global warming with new polar shift are in front of it, 26,000 years later.
