the person behind it, nicholas copernicus was the kind of at the end of his life. the year year the book was published was the year he died which is interesting when we look at contrast for the next book. he was 70 years old when this book was published. he had been working on the idea and considering publication for many years. i'm sure the idea that this would be a threat to the church was reason for him not to come right out and publish it right away. he didn't really, as i said suffer from publishing this, it did make the band book list for the church. the model is essentially the sun on the diagram is at the center of the universe and the bodies rotate around that. when previously the gpo center model was the idea that the earth was at the center of the universe and all of these celestial bodies rotated around that. so this proposal that takes the earth, or our world around the center of things was considered a crazy, radical idea that was not acceptable for those who believed that the earth was the center of the universe. copernicus magnum opus is published t
