The scientist Mr. César Estéban gave a lecture titled "Astronomy for Skeptics" where he explained the differences between astronomy and astrology. He discussed the history of astrology and showed that horoscopes have been consistently incorrect, as the constellations have shifted positions over thousands of years. Through experiments and science, it has been proven that traits like aggression are not influenced by astrological factors like the planet Mars, and that people's personalities do not depend on their zodiac signs as horoscopes claim.
