Astrology, the study of the impact of stars on human affairs.
It's a pity that astrology doesn't actually study anything outside our solar system. One star and a couple of planets (astronomers are debating what constitutes a planet, so we might have a few more or less than we are used to) are hardly the multiverse, but there is still plenty of information to go around.
A competent seer can apply the concept of oneness, observe the dynamics of any system (chicken bones, planets, or oneself) and inter- or extrapolate from there.
So it does work - if the astrologer groks the situation well.
It doesn't work however when you observe a very vague dynamic and claim it is accurate on a personal level. 12 boxes for billions of people? Stereotyping doesn't work.
Contrary to popular belief, the stars do not determine one's destiny.
Everything is connected to everything; everything affects everything.
Therefore, it is true that the stars affect people; however, this is not a one way connection! People affect the stars too.
The next time you think your destiny is determined by the stars, think of this: the destiny of the universe is determined by your heart.
Everything moves, breathes, lives, Loves, IS as One.
