A thing which is believed by most of peoples, how it is bogus?
It hardly matters how many people believe because when a lie is told repeatedly by different people again and again it becomes the truth..A few people may be able to look through the lie which does not mean they are wrong ..
Pay no mind to those who talk behind your back, it simply means that you are two steps ahead !!!
Both science and astrology are based on facts. Astrologers think that there is some power who controls us, and the position of heavenly bodies like sun, moon, star will decide weather some good or bad will happen with us in future, where as a scientist thinks that we (the man on earth) can control situations and facts that happen surrounding to him. Researches and experiments are going in on the both fields, one is trying to prove that nature controls us and other is trying to prove that human on earth can control nature by inventions and research. No one of either can completely ignored.
May be, because there are many evidences there which prove that no one can predict future. If you remembered, a prediction was saying that world will come to end in year 2012. It was claimed that the predictions of Maya calendar came true, and this prediction will also be true. But the truth is in front of everyone.
But,there are believers of Astrology. Some are of the opinion that Astrology is both Art and Science. Doyou remember Bejan Daruwalaa? He is well known for his prediction. I remember I used to read his predictions in all well known Print Media.
