How did Galileo's work come into conflict with thechurch and how was it resolved?

He was challenging the legal authority of the church, they forced him to recant his theory. He then lived under house arrest for the rest of his life until death.

The Church and Galileo were at odds with each other because Galileo asserted that the earth orbits around the sun; in other words the sun is at the centre of the universe. The church disagreed because the Bible states that the Earth is at the centre of the universe. Unfortunately, Galileo did not have any evidence to prove his hypothesis. Evidence supporting Galileo's theories has been found in the centuries after Galileo's death. The conflict was resolved when Galileo withdrew his assertions based on the lack of evidence.
