Okay, so astrology to me sounds extremely unscientific. But I haven't read anything on the subject, and other than knowing that it's something a lot of scientists thing is.. unscientific. To be perfectly fair, I can't just dismiss it because other people dismiss it.
I'd like to be able to dismiss it for scientific reasons. Because I was reading my horoscope, and I was like, "Hmm, well these are extremely vague statements that could apply to anyone and I don't particularly identify with." But then I was reading a friends, and I majorly freaked out because of how accurate it was.
So because of that, I now want to know the truth. Either astrology works or it doesn't. Does anyone know how I could go about determining this? I mean, does anyone have any books or online articles that they would recommend? I'd really appreciate it. I just want to understand.
Here's a link:

In brief, there is no evidence from properly conducted trials that astrology can predict future events at a rate better than chance. In addition physics as we currently understand it precludes any possible effect on us from objects so far away.
Astrology can appear to work through a variety of cognitive biases or can be made to appear to work through various forms of trickery. For example when someone is majorly freaked out by the accuracy of a guess (and with a large enough population reading a guess it's bound to be accurate for some of them) that is much more memorable and much more likely to be shared with others than times when the prediction is obviously wrong. As such the availability heuristic might make you think that such instances are far more common than they actually are, while the actual frequency is entirely explicable by chance alone.
So our world would look exactly the same without astronomy? (I'm kidding of course but that statement should require further qualification)
