[Serious] Do you believe in Zodiac stuff?

It's not spot on at all, actually. It's vague enough where it will apply to just about anything.

The silly thing about astrology is when it was invented in the Roman era the constellations were much different locations than they are today so even if they did apply then (which they didn't because there is no science behind it) they definitely wouldn't apply today. Because of the procession of the equinoxes, the equinox and solstice points have each moved westward about 30 degrees in the last 2,000 years.

Thus, the zodiacal constellations named in ancient times no longer correspond to the segments of the zodiac represented by their signs. In short, had you been born at the same time on the same day of the year 2,000 years ago, you would have been born under a different sign.

Precession of the equinox is caused by the fact that the axis of the earth's rotation (which causes day and night) and the axis of the earth's revolution around the sun (which marks the passage of each year) are not parallel. They are 23 l/2 degrees away from lining up; that is, the earth's axis of rotation is tilted. This tilt also causes our seasons, a fact that Ptolemy did understand but that many people do not understand even today. Ptolemy understood that the rotation axis of the earth was slowly precessing, or moving in a circle, with an angular radius of 23 1/2 degrees with a period of around 26,000 years. He deduced this from comparisons of data taken by the ancient Sumerians 2,000 years before his time. He did not understand what was pushing the precession, but he did understand the motion. We now realize that the sun is rotating with a period of around 30 days and that this causes the sun to bulge at the equator, which causes a torque to be exerted on the top like motion of the earth's day and night cycle. There is also a small 18.6-year variation caused by the moon's orbit around the earth, and the moon also has a small effect on precession; however, the sun's equatorial bulge is the main cause of the precession of the equinox, which is why your sign listed in the newspaper, by Sidney Omar for instance, in most cases is removed by one sign from the modern, actual position of the sun at your birth.
