The Progression to Proving a Heliocentric System

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

During most of the 16th and 17th centuries, it was not easy for scientists to make new discoveries and present them to the world. The Catholic Church, a dominating force during that period, persecuted anyone who would spread ideas and opinions that contradicted what the Bible stated. Both Copernicus and Galileo believed in the heliocentric theory, also called Copernicus theory, which stated that the sun was at the centre of the universe and the earth revolves around it. However, the Catholic Church did not agree with this idea because the Bible stated that the earth was at the centre of the universe and the sun revolved around it, which is the complete opposite. Due to this disagreement, Copernicus and Galileo were threaded by the Catholic Church and

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

Before the scientific revolution people believed that Earth was the center of the universe. That was widely believed by everyone until Nicholas Copernicus said that the sun was the center of the universe and the Earth orbited around it. Document one

Astronomy was a highly debated topic between scientists and the Roman Catholic Church. The Roman Catholic Church believed that the Earth was the center of the universe and there was a place for all of the gods/zodiacs in it. An astronomer from the Middle Ages, Ptolemy, created the drawing of the universe which depicted the Earth in the very center of the universe, or geocentric. The geocentric universe, also contained an outer name in latin translating directly to “The Empire of Heaven and the Home of God and the Elect( document C )”. Contrary to the beliefs of the Roman Catholic Church another astronomer from The Renaissance created a sun centered universe or heliocentric. This astronomers name was Copernicus, he created his universe based on observation of the movement of the planets and mathematics. During the Middle Ages it was strongly believed that the universe was geocentric, but now astronomers like Copernicus have disproved these beliefs with concrete

So when Copernicus brought up the idea of the heliocentric earth it came in conflict with the Church. In Document C it sates "Ptolemy... developed a theory of the universe that was adopted by most scholars during the

Document 3 shows how Galileo’s observations of the moon and laws of motion supported Copernicus’ heliocentric model. He discovered that the moon has craters, and is not a perfect sphere like Aristotle said. This was able to prove that Copernicus was correct. However, the Church disagreed and disliked his work. It was rejected by the Church and he was forced to recant or face execution.

Anybody can tell just by looking at the diagrams of the solar system from the two different time periods that there was a big gap in between the thoughts of the two men who made them. Ptolemy, the man who made it in the medieval period, made people believe that the earth was in the center of our solar system, and the sun was the third planet from the earth. He also made people believe that, “the outer sphere… the Empire of Heaven and Home of God and the Elect” (DBQ Online Document C). These facts were not only untrue, but they also caused everyone to believe that this was correct.

Copernicus published "On the Revolutions of the Celestial Spheres" in 1543 , sparking off the scientific revolution and a new era of astronomical thought. This theory explains that the sun, not the Earth, is the center of the solar system and planets move in a circular motion around it. This had many social, intellectual and religious made of huis idea. For instance, this theory brought into question the strict reading of the Bible and philosophies of the Catholic Church.

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

The first theory of the placement of the planets and stars to disprove the theocentric theory, God centered, was the geocentric theory. This idea began with the philosopher Aristotle in fourth century B.C. Greece, and was expanded and better explained in second century A.D. by Greek Astronomer Ptolemy. The main point of this theory was that the Earth was the center of the universe. This was “proven” by the observation of the sun moving around the earth every day, as seen in the

The Scientific Revolution is the qualitative jump in sciences in the 17th century. New discoveries in natural science, engineering, geography rejected many traditional ideas and a common picture of the world. Aristotle, Claudius Ptolemy, and Christian Theology represented the universe as geocentric conception where the earth was motionless and in the center of concentric spheres. (479) Such representation was supported till Nicolaus Copernicus (1473-1543) argued Ptolemy's conception and suggested heliocentric understanding. His conception opened the Earth as a planet where the moon took place as Earth's satellite and the sun was the center of planets. Also as Copernicus, Tycho Brahe and Johannes Kepler disagreed with Ptolemy's geocentric system. Based on the Brahe's work, Kepler came to conclusions that each planet moves in an ellipse and were able to calculate relations between planets' size and

Galileo Galilei was also a supporter of the Copernican Theory. Galileo believed the earth, and other planets, rotated on its axis around the unmoving sun. He used his new invention of the telescope to prove Copernicus’ theory. With the telescope, Galileo found sunspots on the earth’s moon, which gave proof to him that the heavens were not perfect and changeless but were more like the changeable earth. iv He also discovered Jupiter and the four moons that revolved around it. He only discovered one moon revolving around the earth. Galileo therefore stated if Jupiter were to revolve around the earth, then the earth would have to have at least four moons, and it doesn’t. v The Church objected Galileo’s theory because the Bible said the sun moved through the sky. Being totally rejected by the church, Galileo was forced to take back what he had written and was also prevented from any further teachings of his theory. Galileo was condemned by the Catholic Church for his ideas. The Church succeeded in silencing Galileo but couldn’t stop the advancements in science.

Nicolaus Copernicus was an astronomer who arose the Heliocentric Theory which caused the scientific revolution. Copernicus discoveries were very important, and impacted science to this day. Copernicus constructed his data from his astronomical observations of sun-centered cosmology. The Heliocentric theory is the belief that the sun is in the center of the universe and all the planets revolve around it. The Heliocentric Theory contradicts The Geocentric. “Copernicus's heliocentric solar system named the sun, rather than the earth, as the center of the solar system”. (http://www.biography.com/).

The use of the telescope led him to discover new characteristics of space and the solar system. He discovered Jupiter’s four largest moons and the rings of Saturn. He also discovered that the Milky Way galaxy is comprised of stars. The observation of mountains on the moon was made by Galileo as well. He also made numerous discoveries within these discoveries.
