The first to develop a sun-centered model of the universe, known as heliocentrism, was the ancient Greek philosopher Aristarchus of Samos in the 3rd century BCE. However, the model gained significant prominence and acceptance in the 16th century thanks to the work of Nicolaus Copernicus, who proposed a detailed heliocentric system in his landmark book "De revolutionibus orbium coelestium." Copernicus's ideas laid the groundwork for the later developments in astronomy by figures like Galileo and Kepler.
waterfall model is suitable for this as the requirements are clear and it is a simple model to develop.
Both Models Show That Celestial Objects Have Circular Paths
Medieval philosophers primarily adhered to the geocentric model of the universe, which posited that the Earth was at the center of the universe and that all celestial bodies, including the Sun and stars, orbited around it. This view was largely influenced by Aristotle and later reinforced by Ptolemy's astronomical system. The geocentric model was dominant until the heliocentric model proposed by Copernicus gained acceptance in the Renaissance.
Ptolemy developed the geocentric model of the universe, which positioned the Earth at the center and proposed that all celestial bodies, including the Sun, Moon, and planets, revolved around it in circular orbits. This model, detailed in his work "Almagest," dominated astronomical thought for over a millennium until the heliocentric model proposed by Copernicus gained acceptance. Ptolemy's system also included the concept of epicycles to explain the observed retrograde motion of planets.

A model of the universe is known as a cosmological model. These models aim to describe the structure, origins, and evolution of the universe based on various principles and observations. Astrophysicists develop and refine these models to better understand the vast expanse of space and time.
This is called the Geocentric model, from the latin prefix "Geo-" for earth or ground. This was dropped by the scientific community at the beginning of the renaissance for the Heliocentric model, which states that the sun is the center of the universe. However, even this has been abandoned. The general consensus now is that the universe has no definite center or, if it does, we can never find it due to the dimensional 'curvature' it has.
Aristotle did not develop the geocentric model; it was proposed by earlier Greek astronomers. Aristotle supported this model in his work "On the Heavens" around the 4th century BCE, arguing that Earth was at the center of the universe.
Ptolemy The correct answer is Copernicus. I just took the test.

Aristarchus of Samos was the first person (that we know of!) that proposed a heliocentric model of the universe, as early as about 200B.C). His model was rejected mainly because of Aristotle's influence.Copernicus was the next person to propose a heliocentric model of the universe which was published in 1547. although very controversial at that time, this model was the one that caught on.
Copernicus suggested a heliocentric model of the universe. Meaning, the earth was the centre of the universe and other planets had to orbit around the earth. This model of the universe was against Ptolemy's model of a geocentric model; a stationary Earth at the centre of the universe.
No, Aristarchus of Samos proposed a heliocentric model of the universe with the Sun at the center and the Earth revolving around it. This idea was contrary to the prevalent geocentric model at the time.
