In an article published this month in the journal “Church History,” Kelly clarifies some popularly held notions around Galileo’s travails with the church. But an examination of the fine details of Galileo’s conflict with church leaders doesn’t bear that out, according to English department distinguished research professor Henry Kelly. Many people believe that Galileo was hounded by the church for almost two decades, that he openly maintained a belief in heliocentrism, and that he was only spared torture and death because his powerful friends intervened on his behalf. Avaliable .Today virtually every child grows up learning that the earth orbits the sun.īut four centuries ago, the idea of a heliocentric solar system was so controversial that the Catholic Church classified it as a heresy, and warned the Italian astronomer Galileo Galilei to abandon it. ¿Quién fue Galileo Galilei? ¿Qué hizo?

Shortly before he died, he had to retract and deny the truth to avoid being burned at the stake. With as much recklessness as enthusiasm, Galileo made his results public even knowing that contradicting the geocentric theory (sun revolves around the earth) could lead him to be charged heresy. This theory says that the earth revolves around the Sun. With his new and improved telescope, he began to observe the stars and gather evidence that would end up supporting the heliocentric theory that Nicolás Copernicus formulated a century before. The success of his telescopes brought him fame throughout Europe and a lifetime position at the University of Padua in Padua, Italy. Inspired by the future applications of this new and unknown artifact, Galileo built his own telescope, soon surpassing the resolution and possibilities of the original instrument. Little did they know that this new discovery would change Galileo’s life forever. In 1609, a former student told him about a new Dutch discovery, monocular (telescope). Portrait of Galileo Galilei (Justus Sustermans, 1636) From that moment, he began to combine teaching with research and the invention of new scientific instruments. Some historians say that in a low voice, just after abjuring, he murmured the famous phrase: “Eppur si muove” (in English: “and yet he moves”), referring to the movement of the Earth around the sun.portant discoveries in the field of mechanics, he earned a position as professor of mathematics at the University of Pisa. At 25, after some imbeing burned at the stake. He decided to focus on his true vocation: physics. In addition, his low tolerance towards authority, ignorance, and lack of critical thinking of his teachers, led him to leave the university at age 21.
