Hi Probablist
Yes, astrology definately can. Astrology was a tool for survival in its early conceptions, a divining tool for survival. People eventually learned through observation of the stars that they could predict things.
Though mainstream astrology omits the core divining nature of it (to maintain its secular harmlessness and 'entertainment' value), divination is astrologys' roots.
There are many methods to determining the future of things, a few of these being transits, electional & event astrology, and last but not least horary astrology. We can look at the natal chart (birth) of the thing inquired after --whether it be a rock, a person, or a building or launch of a business, and with transits we can investigate what should come of the thing. We can also ask a question about the thing enquired after (horary), and should we be truely concerned, this is also a reliable and much simpler method to determine what shall come of the thing, especially since we have one aspect of it in mind.
It
could say something about the future of mankind, but as always, there's a bit of the free-will element; but astrology will greatly describe our tendencies and what is most likely to happen. It is up to the astrologer to be skilled and objective enough to determine such an answer securely.
