Astrology is a pseudoscience which uses the position of celestial objects (stars and planets) to make predictions about a person and his future. But as science developed and experiments were conducted, the reliability of astrological predictions diminished.

Birth of Astrology

In times when there were no maps, people would rely on the position of stars to find their way. They observed that combination of stars formed patterns known as constellations. 12 constellations were identified and based on the dates when the sun would enter the constellation a person’s sun sign was decided. Many discoveries have been made since then. Firstly, there are not 12 but 13 constellations (Ophiuchus is the 13th constellation). Secondly, Earth’s wobble (Earth has a wobble cycle of 26000 years) on its axis causes a slip in the dates when the sun enters these constellations. So though the sun might have been in the Aries constellation in the month of April thousands of years back, now it is in the Pisces constellation during that month.

Astrology is not science

Astrological interpretations cannot be experimentally proved. The basis of its interpretations goes against the laws of physics and biology. Planets are so far off from earth that it is implausible for them to exert any influence (gravitational or otherwise) on the earth’s events. The magnetic field produced by household appliances is far stronger than that produced by distant planets.

Astrology and Chance

As per an experiment, astrologers were asked to match the birth charts with a person. The success rate expected was 100% as per astrologers. But when the experiment was completed, the success rate was found to be 51%. This is equivalent to the prediction of getting a head or tail while tossing a coin. Hence, astrology is actually no better than chance.
It is better to make plans for yourself and stick to them rather than relying on predictions.
