The Heliocentric Theory vs. The Catholic Church Essay

Ptolemy, a Roman astronomer came up with the theory that the universe revolved around Earth and all the creatures inhabiting it (Doc. C). This theory, The Geocentric Universe of Ptolemy, was adjusted by most of the people during The Middle Ages. However, much later on, Nicolaus Copernicus, a Polish astronomer, disagreed with Ptolemy’s theory. With his use of math and reason, he came up with a new theory called The Heliocentric Universe of Copernicus (Doc. C). He said that the universe & Earth itself revolves around the sun. The Church denied this theory because they did not want to be proven wrong. If the Church was wrong about this part of the universe, this would then cause man to wonder what else they could be wrong about, or even lied to them about. This new theory taught men to think for themselves and not to rely on the Church for

Johannes Kepler (1571-1630) was a German astronomer who believed in the heliocentric theory. Kepler is a clear example of the narrow line that separated science and religion. Nonetheless, his ideas would show that things could be solved through reason alone. He believed that the harmony of the human soul could be found through numerical relationships that existed between planets. He found that the planets: Mercury, Venus, Earth, Mars, Uranus, Jupiter, and Saturn all revolved at different times. For example, the earth revolved around the sun in a year while Saturn revolved around the sun in fifty years. From this, Kepler found a mathematical ratio, nine to the two-thirds power, to explain this phenomenon. This was revolutionary to humanity’s place in the universe. People were shocked that the universe could be explained by math alone rather than religion. This went strongly

While the Roman Catholic Church believed that the earth was the center of the universe, Nicolaus Copernicus’s discovered that the Earth actually was one of the planets hat revolved around the sun. “For, in the first place, they are so uncertain about the motion of the sun and moon that they cannot establish and observe a constant length even for the tropical year. (Document 1)” The church belief did not make sense because it was wrong. They were going off wrong information that they could not establish a constant year, which confuses people. Nicolaus said that the earth moved around the sun, which made more sense and

Aristotle’s model of the universe was a geocentric universe. This meant that the Earth was at the centre of the universe and that all stars were on a celestial sphere. A celestial sphere is an imaginary sphere which acts as a dome around the Earth from which you can see the stars and the universe. Although Aristotle’s model was good for its time it could not explain retrograde motion of the planets.

Galileo Galilei was an Italian philosopher born in 1564. As an adult, he didn’t believe the universal geocentric theory of the planets and heavens which was established by the

In this piece, Galileo is responding in letter to the Grand Duchess of Tuscany Christina in regards to reports that she had criticized the theories of Copernicus, which Galileo felt was along the correct line of thought for the heliocentric hypothesis. The heliocentric hypothesis was the belief that the planets, including Earth, revolved around the sun, rather than the heavens revolved around Earth. This was greeted with great skepticism by many during this time period with religion still the main focus of civilization. It was with this letter that Galileo attempted to convince the Grand Duchess that her criticism was misplaced and

In the early medieval period, the masses believed that earth was at the center of the universe and everything revolved around it. “...the judgement of many centuries has approved the view that the Earth remains fixed as center in the midst of the heavens…” Nicolaus Copernicus thought that this idea was absurd and continued to explain that the Earth actually moves. He was afraid to even discuss the idea as anyone during the period would just reject it immediately. The Earth being flat was in part influenced by religion and by writing his theories, he was almost apologetic for suggesting the heavens were different from what almost all people believed. “...that the earth is situated in the third sphere and revolves with great speed around the sun, is a very dangerous thing, not only by irritating all the philosophers and scholastic theologians, but also injuring our holy faith and rendering the Holy Scriptures false.” The change in culture was seen as a danger to religion as the new ideas went against a lot of factors in religion. The strict religious ideas caused almost a cultural revolt for new ideas. But because religion was being changed radically, it left room for new ideas like this to start spreading to the

Nicholas Copernicus was the first to question the universal truths and teachings of the church. He devised a theory that the earth along with the other planets revolved around the sun. This theory disagreed with Aristotle and the old teachings that the universe revolved around the earth, and that man was the center of the universe.

Galileo began to express openly his support of the Copernican theory that the earth and planets revolved around the sun. This challenged the doctrine of Aristotle and the established order set by the Catholic Church. supported the Copernican theory, which supports a sun-centered solar system. Galileo was accused twice of heresy by the church for his beliefs, and wrote books on his ideas.

In 1543 Nicholas Copernicus, a Polish Canon, published “On the Revolution of the Celestial Orbs”. The popular view is that Copernicus discovered that the earth revolves

A: Ptolmaics model suggested that the earth was the center of the universe. This was based around the concept that they believed that the orbit of the planets had to be perfectly circular and they had no idea just how far the planets were from the earth which meant that they could not account for the lack of stellar parallax. Or rather, if the earth was moving, then why don’t we see the stars at a different angles at different times in the year? They used this reasoning to justify the idea that the earth must be stationary.

Nicolaus Copernicus was the first to state that the earth is not the center of the

Nicholas Copernicus is considered one of the founders of modern astronomy. His discovery's led him to the conclusion that the Earth rotates on its axis and that it, like the other planets, revolves around the sun. His discovery's influenced scientists and astrologers that came after him, such as Galileo, Newton and Kepler.

Johannes Kepler was a German astronomer and mathematician who lived between 1671-1630. Kepler was a Copernican and initially believed that planets should follow perfectly circular orbits (“Johan Kepler” 1). During this time period, Ptolemy’s geocentric theory of the solar system was accepted. Ptolemy’s theory stated that Earth is at the center of the universe and stationary; closest to Earth is the Moon, and beyond it, expanding towards the outside, are Mercury, Venus, and the Sun in a straight line, followed by Mars, Jupiter, Saturn, and the “fixed stars”. The Ptolemaic system explained the numerous observed motions of the planets as having small spherical orbits called epicycles (“Astronomy” 2). Kepler is best known for introducing three

The Catholic Church played an important role at the time when all the works in which the movement of the earth was admitted, Catholics were forbidden to teach, and even read, the Copernican theories. The “Copernican Theory” modeled some problems of enormous importance for Christian’s obviously theological nature. Leaders like Martin Luther and John Calvin told us that Scripture brandished against Nicolaus Copernicus and provoked repression against its followers, but generally abandon the fight Protestantism once the “Theories of Copernicus” were confirmed with indisputable evidence. In this paper, I will first evaluate the history about how “Copernican Theory” and its model of the earth came into existence. I will also analyze the “Copernican Theory” in light of Churches idea of the earth being flat. I will ultimately argue that Nicolaus Copernicus played an important role in the history of Philosophy of Science.
