Man Isn’t Center of the Universe Anymore?
Before the sixteenth century, the common knowledge of astronomy was based off the Pythagoras, Aristotle, and the Ptolemaic model. They said the Earth was the center of the universe and everything, including the sun, planets, and the heavenly spheres rotated about its center. Aristotle established the principle that there were only seven planets considered wandering stars: Earth, moon, sun, Venus, Mars, Mercury, and Jupiter. Anything besides these stars were fixed stars. He postulated that the heavenly bodies, or the solar system did not move. This made complete sense at the time because it did account for every planetary motion and it was what the church believed. Claudius Ptolemy came up with this …show more content…
In 1514, he first wrote about his new model called the heliocentric model in his manuscript titled Commentariolus. He radically changed the idea of astronomy, however he did keep some basic ideas. His theory defined the Sun is the center of the Universe and the Earth and other planets rotated about it. The moon rotated about the Earth in his model still. He agreed with Aristotle and keep the ideas of the perfectly circular celestial spheres. He also kept the epicycles in his model, but tweaked them. This idea was extremely radical at the time because it makes the Earth, and therefore man, no longer the center of the universe and also no longer important anymore. The Church was not going to stand for this view because it goes against everything it teaches. The main reason why this was never published it was because he feared the repercussions of the church. Thirty-nine years later, De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres) was published only because he was convinced by Rheticus to do so on his death bed in …show more content…
Some disagreed with it completely, like the Roman Catholic Church and some astronomers. Most other astronomers agreed with his ideas to an extent before they began tweaking the model or idea to improve upon it. The first historically important astronomer to disagree with his work was Tycho Brache. He was a very talented, trained astronomer all over Europe. Brache discovered a new star, but known today as a supernova, in 1572 and a new comet in 1577. This did not go along with the Aristotelian view because new stars can never come about because the heavens are perfect and unchangeable. This alone would mean the Aristotelian view was incorrect, but he didn’t seem to mind this, but did mind that the Sun was the center of the universe. He could not agree with heliocentricism because that would mean the Earth was not the center of the universe and man was no longer important. Instead, he created a hybrid theory, mixing the old geocentric and new heliocentric models together. In this model, he decided the Earth was still the center; the moon and sun would orbit about the Earth and then the other planetary object would orbit the
