The Sun-centered theory

Church Controversy
Biblical references saying that
"the world is firmly established, it cannot be moved."
Psalm 104:5 says, "the Lord set the earth on its foundations; it can never be moved."
Ecclesiastes 1:5 states that "And the sun rises and sets and returns to its place"
- By 1616 Galileo went to Rome to try to persuade the Catholic Church authorities not to ban his ideas.
- Cardinal Bellarmine, acting on directives from the Inquisition, delivered him an order not to "hold or defend" the idea that the Earth moves and the Sun stands still at the centre.
- 1632, Galileo published The book, Dialogue Concerning the Two Chief World Systems which support his theory.
- The book made him arrested in charge of heresy because of the sun center theory.
- Galileo was sentence to shut in his own house for the rest of his life and all of his book were banned .
