Hello!… and Welcome to learn Immense where you can enhance your knowledge to the wider aspects of the World. Let me tell you what you can expect to learn today from this post. The most prime initialisation of Astronomical and celestial observations scales its origin from the earliest civilizations of the world. Let me just give you a quick introduction about the observations.
THE GEOCENTRIC MODEL.
Astronomers from the earliest centuries postulated a model of the universe whose basic features had been defined by Aristotle 2,000 years earlier. The idea was pretty simple. Earth was placed stationary at the centre of the universe and the Sun, Moon, and other planets all revolve around it. This postulate was similar to a model where each object was fixed to a spinning crystalline sphere. Everything was fixed onto a spherical model. Rest was the natural state of any object, so a possible mysterious force which they then called Aether was believed to have existed. Medieval people often pictured the whole universe similar to that of concentric spheres.
THE NEMESIS OF THE GEOCENTRIC MODEL.
The downfall of the Geocentric model which was proposed by Ptolemy came into action during the Renaissance Era where a broad cultural awakening that included science and politics as well as art happened. The inhibition of perspective studies came into existence. The scientists and the creators of the Renaissance once again began to ask profound yet meaningful questions about the universe. How possibly do we know that the Earth is the centre of the universe? What is the ardent way to understand the motions of the stars and planets?.
THE HELIOCENTRIC REVOLUTION.
The heliocentric model is the astronomical model in which the Earth and planets revolve around the Sun at the centre of the Universe. Historically, heliocentrism was strongly opposed to geocentrism, which placed the Earth at the centre. The Heliocentric model was initially proposed by Aristarchus of Samos, A Greek astronomer who also invented the Lunar Dichotomy. But It was not known until the 16th century that a mathematical model of a heliocentric system was individually presented, by the Renaissance mathematician, astronomer, and Catholic cleric Nicolaus Copernicus, leading to the rise of the Copernican Revolution. Copernicus made few new observations. He finally concluded that the prediction of planetary positions would be simpler if we imagined that the Sun is at the centre and Earth is one of the Sun’s orbiting planets.
During the earliest of human civilization, there were not many possible hypotheses regarding celestial bodies. The Heavens above were of anyone’s guess and the way things were was just the way the gods had made them. It was felt there was no possible need to truly understand them or put them in any sort of order. The Greek scholars changed much of that plot. Some of the most identifiable scholars are Ptolemy, Copernicus, Aristotle and Galileo.
