We know that the Catholic church has a troubled history with the idea of heliocentrism, but when did this history become history? What year would Galileo have gotten away with publishing his book?
In 1632, Galileo and the Catholic Church had a little spat. You may have heard about it. It was partly because he had evidence that contradicted the prevailing geocentric worldview, and partly because, while presenting that evidence, he called the pope a dummy. While it's doubtful that any pope would have warmed to the second offense, few people know when the church changed its opinion on the first offense.
