¿Cómo medimos el COSMOS? (Con Aldo de El Robot de Platón)

The video explores historical and modern methods of measuring cosmic distances. It begins with Eratosthenes and Hipparchus' calculations of the Earth and Moon's sizes. The concept of parallax and trigonometry is introduced to explain distance measurement. Aristarchus' early attempt to calculate the Sun's distance is discussed, followed by the more accurate method using the transit of Venus. Modern techniques, including radar, provide precise measurements of celestial distances.
