What had Sir Isaac Newton to do with the catholic church?
Sir Isaac Newton was an English physicist, mathematician, and astronomer who made many groundbreaking contributions to the fields of physics, mathematics, and astronomy. Newton was a devout Christian and had a deep interest in theology and the study of the Bible. However, he was not directly involved with the Catholic Church.

In fact, Newton was a member of the Church of England, which separated from the Catholic Church during the English Reformation in the 16th century. However, he did correspond with several prominent Catholic scholars, including the Jesuit astronomer Giovanni Battista Riccioli, and had an amicable relationship with them. Newton's theological views were highly unorthodox, and he had a particular interest in studying the mystical aspects of Christianity, including prophecy and alchemy.

Overall, while Newton had some interactions with Catholic scholars and was a Christian himself, he was not directly involved with the Catholic Church or its hierarchy.
I'm thinking of Galeleo. Can you tell me what he had to do with the Catholic church?
Galileo Galilei was a 16th-century Italian scientist who developed the theory of heliocentrism. He argued that the Earth orbits around the Sun, which was considered heretical by the Catholic Church at the time. Galileo was placed under house arrest for the rest of his life by the Church, and all of his writings were banned. His theory of heliocentrism was later proven correct, and he is now considered to be one of the most important figures in the history of science.
