Since Galileo was an astronomer, he also most likely saw the movement of the star's position in the sky as Copernicus did. However, thanks to his support, Galileo came under intense scrutiny. The introduction reads: “Galileo was forced to renounce his scientific discoveries and was sentenced to perpetual house arrest. His books were burned." (p.191). This action taken by the Church shows how the further discoveries made by Galileo aroused fear because they went against some of their teachings. Fortunately, his trial became the platform where his work was saved and disseminated throughout Europe, which certainly helped him gain supporters, prompting more revolutionary changes in thought. However, the reason why Galileo's discovery aroused greater acceptance was not only punishment by the Church. In fact, I think he gained more acclaim because he created a tool that helped him see and understand the spheres of the world better. Although the idea for this instrument was not entirely his, he managed to make one in which he says he "perceived objects satisfactorily large and close, since they appeared three times closer and nine times larger than those seen with the naked eye" (page 192). However, his work did not end there. “It would be superfluous to enumerate the number and importance of the advantages of such an instrument… I often observed with wonder and pleasure both the planets and the fixed stars… I began to look for (and eventually found) a method by which I could measure their distances” (p.192). Actions like these are why I believe people began to change and believe in a heliocentric system because they were given plausible information
