Not quit, he went to prison because he proved that the sun turned around the sun and not the sun turn around the earth. But the Church wont believe him so they sent him to jail for "heresy".

Heresy means it is like you lie at a religious reason. :)

Answer 2

Galileo Galilei was sentenced to house arrest, not prison, by the Catholic Church for advocating the Copernican theory that the Earth revolves around the sun, which was considered heretical at the time. His support of this heliocentric model contradicted the Church's geocentric view of the universe.

Answer 3

He was not actually sent to prison but placed under house arrest and had his movements restricted by the Pope on suspicion of heresy.
