How does astrology work?
This is my hypothesis on how astrology works:
The Sun (which is mythologically associated with Apollon, who plays the lyre) sends out a sound, which we as human beings cannot hear, but which can be registered by machines. This sound (or music, if you like) is created by the activity inside the Sun. The Sun's activity (and hence its music) is again influenced by the movements of the planets. At the moment of a child's birth the Sun's music is printed into the natal chart, which is then object to the continuous music from the Sun.
The problem with this hypothesis is that it does not include the Moon.
