Galileo's Dialogue Concerning the Two Chief World Systems

Galileo's "Dialogue Concerning the Two Chief World Systems" is a scientific debate comparing the heliocentric model, where the Sun is at the center, with the geocentric model, where Earth is at the center. Presented as a conversation among three characters, it advocates for the Copernican system, challenging traditional views endorsed by the Church. The work played a key role in promoting scientific thinking and evidence-based astronomy, despite controversy and opposition from authorities. It highlights the shift towards understanding our universe through observation and reason rather than solely relying on accepted doctrines.
