i think Death Boo Z was touched in the wrong place by tarot cards.

Anyway, in regards to astrology, i find it hard to believe that the movements of various balls of gas a bajillion miles away have an impact on my life. That being said, if you look at in a purely scientific way and take into consideration some of the modern theories about the nature of the universe, and the fact that we still dont know jack about how it really operates.....well then in that case it may be possible, although still very very far fetched.

From the point of view of newtonian physics, and every action having an equal and opposite reaction, you could say that predicting the future is possible ("but quantum mechanics blows that outta the water" - Samantha Carter, SG1 )

In short, i wont dismiss that its possible, but i also dont believe some old lady sitting in a tent can do it.
