Heliocentric Theory

The Geocentric and Heliocentric theory have been a big part of the change in European beliefs as they presented their belief or discovery. Galileo Galilei and Nicolaus Copernicus are the scientists who have discovered or made their thoughts and beliefs on the geocentric and heliocentric theory and had people believe in these theories. In the way that Galileo Galilei and Nicolaus Copernicus with the theory of geocentric and heliocentric is how Galileo Galilei and Nicolaus Copernicus changed the European beliefs. The Catholic Church was a big part on the beliefs as well after they believed in the belief that Galilei made and then Galilei made a mistake and was sent to prison for it and he was sentenced to life, however, he was able to do it on

He was born in Pisa on February 15, 1564. In 1581, Galileo decided to study medicine at the University of Pisa. While being a smart student at that university, Galileo figured he was good at mathematics. He was able to persuade his father into letting him leave that university so he can be a tutor for mathematics. He later was a professor of mathematics and In 1609, Galileo then heard about the invention of the spyglass, a device that would make distant objects appear closer. Galileo used his strong mathematics knowledge and technical skills to improve the spyglass and he would then build a telescope. Later in that same year, he was the first person to look at the Moon through a telescope and then he made his first astronomy discovery. He saw that the Moon was not smooth and that is was mountainous and pitted just like the Earth and he used his newly invented telescope again to study Saturn, to observe the phases of Venus, see four moons circling around Jupiter and also studied the sunspots on the sun as well. Most people at the time that Galilei made the theory that the Earth was the center of the universe agreed with him and thought that the Sun and planets did revolve around the earth.Observations strengthened Galileo’s belief in the theory that the earth and other planets go around the sun making the sun the center of the universe and that theory was made by Nicolaus

He then realized he was looking at a planet and he observed the phases, periods when the planet either appeared to grow or shrink, similar to the Moon.His observation of Venus and its phases this helped provide Galileo with further proof that Earth was not at the center of the solar system.Ie Spring of 1611, Galileo had been working on his astronomical studies for a year and a half. In his mind, he had thought that he had great strides towards lowering the value of Aristotle's findings, while he built up his own reputation and that of Copernicus. He lectured occasionally, and his talks captivated his listeners. That spring, his fame was as widespread as ever, but Galileo Galilei was not fully satisfied with the effects his work was having on bringing change to the Catholic Church. He decided it was time for him to pay an official visit to Rome, the center of Roman Catholic power, to demonstrate his scientific findings. He hoped to convince skeptical leaders including the pope himself of the need to change the Catholic Church's position on several of its doctrines that conflicted with his scientific
