Esteemed members of the tribunal, it is with great honor that I stand before you to defend the heliocentric model of our solar system. I present to you my findings, which are supported by rigorous observations and calculations. Through the use of a refined telescope, I have observed the moons of Jupiter in different positions, suggesting that they orbit Jupiter, not Earth. Such celestial bodies moving independently of Earth support the notion of a universe with the Sun, and not Earth, at its center. Additionally, my studies of Venus's phases have shown a pattern consistent with a planet orbiting the Sun. These findings, along with the work of my esteemed predecessor Nicolaus Copernicus, provide substantial evidence against the long-held belief in a geocentric system. I humbly ask you, dear members of the tribunal, to consider the implications of these discoveries and embrace the scientific progress they represent.
Imagine that you are Galileo Galilei defending your idea of a heliocentric solar system in front of a tribunal. Provide a summary of your defense.
