i know many of the viewers will disregard this message, but to anyone out there who is knowledgable in ancient wisdom i humbly ask: regarding astrology from a scientific perspective, i understand that the tilt of the earth is changing approximately 1 degree per 70 years, and this in turn affects the position of the observable constellations above any point in the night sky. astrologers call it the precession of the equinoxes. if calculating ones zodiac for the time of birth, how would this affect the dates regarding the divisions of the 12 signs? also, would the fact that one lives in the southern hemisphere affect ones birth signs? if so is there a formula to apply to them in order for correction. sorry, i have not yet found an astrology site that is not burdened by dogma and nonscientific assumptions. thanks.
