Precession of the Equinoxes is a 20th century theory of why the Earth moves through all 12 constellations of the heavens over a period of 26,000 years.
It is an answer to why the Earth appears to be moving slowly through one of twelve distinct ‘Ages’, every 2,000 years.
It is believed by modern science to be due to the fact that the Earth wobbles on its axis.
Some even believe that this wobble is due to a discrepancy between magnetic north and true north that appears on a 2 dimensional map.
It is based on an observation that a spinning top wobbles due to the energetic experiences that it is experiencing as it slows down.
However the speed of spin of the Earth is constant and has been for millenia.
The Theory of the Precession of the Equinoxes is based on the belief that the Sun is stationary and the Universe circulates at the same speed as our Galaxy.
Science no longer believes that the Earth is the centre of our Universe.
However its theories are now based on our Sun being the centre of our Universe.
