His observations in the sky spurred on many other telescope makers and astronomers to further explore the amazing and mysterious objects in the sky. Prior to Galileo's conflict with the Church, the majority of educated people in the Christian world subscribed either to the Aristotelian geocentric view that the earth was the center of the universe and that all heavenly bodies revolved around the Earth, or the Tychonic system that blended geocentrism with heliocentrism.

Remembering Galileo and the first astronomers, he did not hesitate to build the telescopes that I couldn't buy. Remember, the idea of the underlying mechanism of gravity wouldn't come until Newton's Principia Mathematica in 1687, which makes this both a reasonable and important question. At his father's behest, Gailieo gave up his. He also turned his telescope toward the Milky Way. The Catholic Church, however, took a far less enlightened view.
