Heliocentric And Geocentric Theory | History of the universe | History of Astronomy | Astrophysics

Today, virtually every child grows up and learning that the Earth orbits the Sun. But, four centuries ago, during most of the 16th and 17th centuries, fear of heretics spreading teachings and opinions that contradicted the Bible dominated the Catholic Church. A type of war between science and religion was in play, but there would be more casualties on the side of science. Before going into the main topic, we will discuss about heliocentric theory. What is the heliocentric theory? The Earth revolves the Sun. That is called heliocentric theory. Actually, helio meaning Sun, and centric meaning in the center, or Sun in the center. In Western civilization, ancient Greek astronomer Aristarchus of Samos, who was an ancient Greek mathematician and astronomer from Ionia, came up with a revolutionary astronomical hypothesis. He was the first person who proposed that the Sun-centered astronomical hypothesis of the universe heliocentric. He also said that the stars were distant suns that remained unmoved, and that the size of the universe was much larger than his contemporaries believed. At that time, however, Aristarchus' heliocentrism gained few supporters, and 18 centuries would then pass. Before Renaissance astronomer Nicolaus Copernicus produced a fully predictive mathematical model of a heliocentric system. Nicolaus Copernicus was born on February 1914-73 in Torun, Poland. Copernicus developed his own celestial model of a heliocentric planetary system. Copernicus' heliocentric theory about the way of the universe had challenged with geocentric theory of astronomer Ptolemy in the second century. Ptolemy's geocentric theory, where the Earth at the center of the solar system. In 1616, the Catholic Church declared Copernicus' theory heretical, because it was viewed as contradicting certain Bible verses. At that time, Galileo received permission from the Church to continue investigating Copernicus' ideas. Galileo Galileo was born on February 15, 1564, near Pisa, the son of a musician. Galileo was a Tuscan, Italian, astronomer, physicist, mathematician, inventor, and philosopher. When Galileo received permission from the Church as a result, the following year, Galileo was ordered to stand trial before the Inquisition in Rome. In Revolutions Copernicus states that the Sun is at the center and the Earth revolves around it while rotating on its axis daily. Nicholas Copernicus and Galileo both scientists held the same theory that the Earth revolved around the Sun. This theory now known to be true.
