Why astrology is not a widely accepted subject?

Astrology is accepted by many people and not by many others. People go to astrologer to get a prediction of their future and get remedies. But still it is not a widely accepted subject of study and research. I think the following are the reasons why it is not widely accepted as a formal subject.

1) Astrology is different than Sanskrit: Most of the astrology books are written in Sanskrit in stead of English. And educationists look astrology as a subset of Sanskrit, not a different subject all together. Most of the computer books are written in English, still nobody tells computer is a part of English. Once somebody knows basic English, English does not help someone to be better computer specialist. Similarly, one need to know Sanskrit to understand the original books, beyond that Sanskrit won't help to be a better astrologer. Astrology is a different stream all together to be taught by astrologer. It should be derived using mathematics not Sanskrit. Probable astrology developed when Sanskrit was the language of the learned people and now English is the common language among educated people. Astrology should have no problem in adopting english in stead of Sanskrit with the mathematical formula intact.

2)Astrology is not 100 percent correct: Astrology is about probability, it does not say with certainty. But the supporters of astrologer claim a hundred percent correct prediction with examples. Opponents discard it with wrong example. Many astrologer predicted Vajpayee will come to power again in 1998 but none predicted the same about Manmohan Singh in 2008 (at least the ones that post in the leading English dailies). Supporters take the right example where as opponents take the wrong one.

3) Why should one believe in astrology: Astrology has not answered why the prediction can come true. Many people claim it is the position of planet and cosmic rays affect one, they are not able to tell why the position of the planets not that of the people around u affect it. Say sun in mercury in 7th house gives an intelligent spouse why not father at 7th house gives an intelligent partner and grand mother in 7th house gives some other type etc. My honest answer is I do not know why the position of one's father does not matter, but that of Brihaspati matters. It can be a subject of research, but it works. We need to answer why before claiming it to be universally accepted. Similarly astrology says 1st house is for self, 2nd is for wealth and all. But it does not answer why 2nd house is for wealth and 7th for spouse.

4) Intuition: Intuition is an integral part of astrology. One can not be good astrologer without good intuition. Same horoscope is predicted differently by different astrologers. Unless intuition can be quantized, or astrology gives any different answers, it can not be accepted as a scientific study.
