11. THE REASON OF PRECESSION OF THE EQUINOXES

The precession of the equinoxes - in other words is the antecedence of the equinoxes.

The precession of the equinoxes (Latin Praecessio aequinoctiorum) – is the historical name for the gradual displacement of points of the vernal and autumnal equinoxes (i.e. the points of intersection of the celestial equator and the ecliptic) towards the annual motion of the Sun. In other words, every year the vernal equinox comes a little earlier than in the previous year. 

Both equinoxes are preceded - and the spring and autumn. And this anticipation should be explained by the fact that the planet is gradually heated.

Generally, once we should remember that moment of equinox (any) corresponds to the time when the total temperature of the substance of both hemispheres is equal in magnitude. That is why in the equinoxes both hemispheres are at the same distance from the Sun.

The largest amount of solar radiation is accumulated by the planet's core. This is explained by the existence at any celestial body the centripetal Field of Attraction, because of the action of which elementary particles accumulated on the surface of the chemical elements of the surface layers of the planet flow down, moving towards the center of the planet. Namely because of this flowing of particles down, there occurs a cooling of the surface layers of the planet and a heating of the core. The more heated the planet's core, the less the value of its Field of Attraction. The less is the Field of Attraction, the slower the layers of the planet cool – i.e. the slower particles flow downwards. It turns out that the more the planet's core is heated, the faster there occurs the warming of a hemisphere. Substance of each hemisphere is external (surface) with respect to the central part of the planet.

An amount of substance in the composition in both hemispheres is the same. And the heating of the core of the planet occurs incrementally – i.e. in every next moment temperature of the substance becomes more and more. That's why when there is a change of the position of poles, and another hemisphere comes to replace a warmed hemisphere, starting to warm up, it warms up a little bit faster. I.e. a little earlier than it was last year, the temperature of this hemisphere compared with the temperature of the second hemisphere. And this just marks the moment of the equinox. Because of this the days of equinoxes occur all the time a little earlier than before.
