I would like to keep this thread on a cerebral level. If your post is closer to an anti-astrology rant, perhaps it would be more apt for the 'Astrology is Hogwash' thread.
I'd like to know more about the science of astrology. Topics that come to mind:
** Jung's studies that correlated 7 aspects in natal charts with successful marriages. (This is, after all, a dating site!)
** Ancient Egyptian data-gathering, upon which ancient and modern astrologers base their understanding of the significance of each planet, each house, each type of aspect.
** The contributions to knowledge of astrological "greats" -- Grant Levi, Elbert Benjamine (pen-name: C C Zain), Donna Cunningham, etc.
** Correlative studies between natal astrology and 'personality theory' as propounded by Myers, Briggs, Keirsey, and other psychologists.
** Any variance between our current (2006) understanding of planetary orbits and that of the ancients.
** Any current scientific studies being done to confirm or disprove the predictive value of astrology.
I wrote a blog about Astrology and Science. If you care to read it, go to http://www.iamscorpio.net/scorpio-blog.html It deals more with how modern scientific discoveries are now confirming the basic concepts of serious astrology (not those horoscopes in magazines and newspapers). I have some historical data as well which I might eventually post but nothing as in depth as you seem to be seeking.
All those years ago when I first began to study Astrology, I had no idea how much it would help me evolve spiritually. It helped me like no church ever could. That's not to say I don't attend. I do. I just don't grow spiritually there. I get spiritual support. That's different.
Sounds like you have done some homework. One way to prove the validity of something is to first prove it on yourself. I have an interesting site i like called astro.com. There is a vast array of knowledge in the astro click portrait section.By clicking the houses,signs,and planets,you can get explanations of aspects. You may be enlightened by what you find
