the real explanation for the precession of the equinoxes here i am trying to formulate shortly what i have detailed in the article found at the address mentioned upper tabimagine two material points with equal masses bounded through a field gravitational one that rotates in vacuum around an axes perpendicular to the straight line that bind them the rotation axis is passing through the system s center of the mass the system is considered in equilibrium so the centrifugal force equalizes the attraction one tabthe two material points have the impulse variable even though the movement can continue non stop due to the conservation of the kinetic moment of the system so due to the inertness tabthe same we can imagine a system made from two parts bound through something that allows them to have the kinetic moment variable but the volumic impulse constant such a system is the earth it is formed from two parts the earth shell and its nucleus bound through a field magnetically the earth s volumic impulse remains constant due to the inertia while the kinetic moments of the two bounded component parts varying more explicit i don t think i could be unless with your help
