Centuries ago, a dominant worldview was followed by most of the population. The medieval worldview primarily assumed that everything written in the Bible was undeniable, that the world was created in six days, that the earth was the center of the earth, and that deep down, unlike most people today, they were not looking for any answer to this question. to their questions, to their doubts, the only true and correct answer was “because God did it”, “because God said so”; “Even in the early Middle Ages, Europeans believed that the center of all truth and experience was in God” (reader, The Scientific Revolution, p. 2). However, this situation was about to undergo a radical change. In the 16th century this radical change took place, mainly in the scientific, philosophical and political fields. With new scientific discoveries, scientists began to reveal and doubts began to disappear as new discoveries occurred, Islam contributed greatly to all these discoveries. Evolutionary doctrines were being called into question, to the point that the new doctrines were much more credible. The Scientific Revolution was one of the main causes of the growth of secularism in Europe at the time. In this revolution, the writings and discoveries of scientists like Nicolaus Copernicus, Galileo Galilei and Isaac Newton led to a new understanding of the universe, a different worldview, which moved from the interpretation of God as the first cause, in an age of reason, in which we live at the moment. Some of the most important scientific breakthroughs in history were made through the experimentation and analysis of these scientists. In medieval Europe, it was generally accepted that the Earth was at the center of the universe and that the sun, planets and stars revolved around it. the planets were like perfect spheres, it was called...... middle of paper...... their speeds; he assured that the movement could be described mathematically. Such experiments by Galileo caused people to question the ideas of the Church. He refuted many ancient hypotheses put forward by the Catholic Church at that time and, through his experiments, brought about a reform that resulted in the beginning of secularism. “The Church concluded that his ideas were in contradiction with both doctrine and Scripture and demanded, on pain of death, that he reconsider his views” (The Scientific Revolution, p. 6). Regardless of what the Church wanted, Galileo insisted that the universe worked like a world machine, that everything could be explained by mathematics, or that it was wrong. “His revolutionary argument was the following: if a physical model did not correspond to the mathematical properties of the phenomenon, the physical model was false” (The Scientific Revolution, p... 6).
