Before dwelling into the social and academic reasons of both celestial perspectives, I must clarify the origins and definitions of each. The Ptolemaic system, also known as the geocentric model, assumed that the Earth was at the center of the universe. It was based upon the idea of circular deferents, epicycles and eccentrics, which accounted for the apparent movements of the planets (Matthews 34). The heliocentric model, which was presented by Nicolaus Copernicus, altered the reference point so that the Sun was at center of the solar system. He understood the relativity of perception, and thus stated that all the celestial worlds went around the sun (Matthews 34).
From an explicit viewpoint as to why the Ptolemaic model was such a widely

Stellar parallax was a noted phenomenon by academics of the 16th century. Despite having knowledge of this event, one could argue that the geocentric model was merely promoted to appease the mind. Believing that the Earth was at the center of the solar system was simple, and aesthetically pleasing. In his work, The Commentariolus, Copernicus comments about how their ancestors believed it was absurd that a “heavenly body, which is a perfect sphere, should not always move uniformly” (Matthews 36). Having the Bible to support their assumptions, I can claim that the populace must have only accepted arguments that reflected the order and regularity of nature.
On the other hand, heliocentrism promoted a perspective that relegated us from the forefront to a secondary position. In the grand scheme of the universe, we were now one of many planets that were orbiting the sun. In the mind of a person from the 16th century, contemplating a world in which they were not at the center must have been seemed imperfect. Ultimately, presented with an ideal system that gave a conceivable explanation of the movement of celestial bodies and allowed for the prediction of natural phenomena, the populace must have been
In his book, Repcheck recounts how a Catholic Church cleric invented a highly complicated theory of the heavens’ architecture. Copernicus made a breakthrough by solving a significant astronomical problem. Everybody except the astronomers had earlier accepted Aristotle’s concept that heavenly objects revolved around the earth in perfectly circular orbits. The astronomers were opposed to this notion since their calculations could not work according to it. Repcheck introduces Ptolemy who described a cosmos in which the earth positioned itself somewhat off-center and other heavenly bodies revolved in one circular orbit inside a second ideal circle at changeable speeds. Even though Ptolemy’s model was rather complicated, astronomers found it to be reasonable in their calculations. Astronomers were still using this new concept even 1500 years later. In this regard, the author starts to bring Copernicus into the picture.
In papal Rome in the early 16th century the “Good Book” was the reference book for all scientists. If a theory was supported in its holy pages, or at the very least not contradicted, then the idea had a chance of find acceptance outside the laboratory. Likewise, no theory no matter how well documented could be viewed with anything but disdain if it contradicted with the written word of, or the Church’s official interpretation of scripture. For these reasons the Church suppressed helio-centric thinking to the point of making it a hiss and a byword. However, this did not keep brave men from exploring scientific reason outside the canonical doctrine of the papal throne, sometimes at the risk of losing their own lives. While the Vatican was able to control the universities and even most of the professors, it could not control the mind of one man known to the modern world as Galileo Galilei. Despite a wide array of enemies, Galileo embarked on a quest, it seems almost from the beginning of his academic career, to defend the Copernican idea of a helio-centric universe by challenging the authority of the church in matters of science. Galileo‘s willingness to stand up for what he held to be right in the face of opposition from Bible-driven science advocates set him apart as one of the key players in the movement to separate Church authority from scientific discovery, and consequently paved the way for future scientific achievement.
A key parallel between the scientific revolution and the enlightenment was the decreasing belief in authority. The scientific revolution lead to great advances in astronomy, mathematics, geography, botany and medicine (7). A key discovery was that of Copernicus’ heliocentric theory (2). The heliocentric theory proposed that the sun was at the centre of the universe as opposed to the earth which was the common belief held strongly at the time. Copernicus discovered that the sun was at the centre of the universe, and that the moon orbited the earth while the earth orbited the sun. This theory raised profound qu...
“Upon this principle they imagin'd the earth rested in the center of the Universe,” the book said, “while all the celestial bodies (which were made for it) took the pains to turn round to give Light to it. They plac'd the Moon above the Earth, Mercury above the Moon, after Venus, the Sun, Mars, Jupiter, Saturn; above all these they set the ...

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 around the sun. The notion is as old as the ancient Greeks however. This work was entrusted by Copernicus to Osiander, a staunch Protestant who though the book would most likely be condemned and, as a result, the book would be condemned. Osiander therefore wrote a preface to the book, in which heliocentrism was presented only as a theory which would account for the movements of the planets more simply than geocentrism did, one that was not meant to be a definitive description of the heavens--something Copernicus did not intend. The preface was unsigned, and everyone took it to be the author’s. That Copernicus believed the helioocentric theory to be a true description of reality went largely unnoticed. In addition to the preface, this was partly because he still made reassuring use of Ptolemy's cycles and epicycles; he also borrowed from Aristotle the notion that the planets must move in circles because that is the only perfect form of motion.
The first record of the movement of the planets was produced by Nicolaus Copernicus. He proposed that the earth was the center of everything, which the term is called geocentric. Kepler challenged the theory that the sun was the center of the earth and proposed that the sun was the center of everything; this term is referred to as heliocentric. Kepler’s heliocentric theory was accepted by most people and is accepted in today’s society. One of Kepler’s friends was a famous person named Galileo. Galileo is known for improving the design and the magnification of the telescope. With improvement of the telescope Galileo could describe the craters of the moon and the moons of Jupiter. Galileo also created the number for acceleration of all free falling objects as 9.8 meters per second. Galileo’s and Kepler’s theories were not approved by all people. Their theories contradicted verses in the bible, so the protestant church was extremely skeptical of both Galileo and Kepler’s
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.
improved by Aristotle. But Galileo came up with a new argument named heliocentrism. In a long
Aristarchus has only one existing book that is “On the Sizes and Distances of the Sun and Moon.” In it he calculated the diameter of the Sun, which is about seven times the diameter of the Earth, and estimating the Sun’s volume is about 300 times the volume of the Earth (the actual diameter of the Sun is about 300 times the diameter of the Earth.) In this book there is nothing indicating his heliocentric theory. Aristarchus’ book on the planetary system with the Sun in the center did not survive. He also added that the universe is many times larger than generally assumed by astronomers, and the fixed stars are at an enormous distance from the Sun and its planets. Aristarchus regarded the Sun as one of the fixed stars, the closest to the Earth.
In 1513, Nicholas Copernicus, composed a brief theory that stated that the sun is at rest and the earth is in rotation around the sun. In 1543, just days before his death, Copernicus published this theory in On the Revolutions of the Heavenly Spheres. This theory was meant to dissolve the long lived belief in Ptolemyís theory which stated, "The earth was at the center because it was the heaviest of objects(Kagan331)." This was a common belief at that time, which supported the religious beliefs that the earth was the center of the universe and God in the heavens were surrounding the earth. Copernicusís theory was shocking, but he published such a controversial theory without sufficient evidence, it had to be considered invalid.
How was the modern model of the solar system formed? Many of its elements come from Nicholaus Copernicus’ heliocentric theory. Summarized briefly, the heliocentric model of the solar system portrays the sun as the center of the solar system with the planets revolving around it. This is contrary to the older and more primitive geocentric model which portrays the Earth as the center of the solar system instead. Nicholaus Copernicus’ theory regarding the movement of the planets and the position of the sun and Earth has had a profound effect on the scientific understanding of the solar system. His ideas were originally met with opposition due to religious beliefs of the time. By publishing his theory, Copernicus set the stage for a drastic and positive change in scientific and religious beliefs.
This past 2 weeks we did a lot of interesting things like watch a superhero comic book documentary and finishing up Beowulf. The story style of Beowulf was new to me because of the characters tone and speeches. I’m used to reading modern stories and the way the author tells it. The Beowulf poet style can be still used to teach or show students and other readers of how people used to tell stories. The whole story of Beowulf was based on the Anglo-Saxon and their culture.
Much to the dismay of the Church, two astronomers Galileo and Kepler had the audacity to challenge the authorities by suggesting that the sun-not the earth-was at the center of the universe. The church had a stronghold on the way the spiritual and physical world worked, so these discoveries only added to the Church’s resistance to their aims. Their discoveries came only after Kepler and Galileo began to question ancient theories about how the world functioned. These ancient truths were widely held but were inconsistent with the new observations that they had made. Kepler had discovered the laws of planetary motion which suggested that the planet would move in elliptical orbits, while Galileo followed with his discovery of the principle of inertia. Galileo concluded his finding b...
The cosmological views of the Late Middle Ages revolved around the Aristotelian-Ptolemaic theory. This theory was adapted by the Church to explain the universe, as a result, many people believed the Aristotelian-Ptolemaic theory was perfect because the pope believed it, and he was infallible. The Church took many ideas from the Bible. One example would be that they believed that the universe was six thousand years old. Another major idea was that the universe was made up of a series of concentric spheres with a motionless earth at the center. Planets, commonly referred to as “heavenly bodies”, were made up of crystalline substance and moved in circular orbits. Stars are attached to these planets and are “pushed by angels”.
