How did Copernicus’ Theory Change the World?

Nicolaus Copernicus, the father of modern astronomy, was a Polish astronomer. He was the first modern European scientist to propose the Heliocentric Theory of the Universe, which states that the Earth and other planets revolve around the Sun. Prior to the publication of his monumental astronomical work, The Six Books on the Revolutions of the Celestial Spheres, in 1543, European astronomers held that the Earth was at the center of the universe, a position shared by most ancient philosophers and biblical writers. Copernicus argued that the Earth rotated around its axis on a daily basis and that gradual shifts in this axis represented seasonal changes, in addition to correctly postulating the order of known planets from the Sun and a relatively accurate estimate of their orbital periods.

For more than 1,000 years, Ptolemy’s system was accepted European cosmology, but by the time Copernicus came, astronomical evidence had thrown some of his theories into confusion. Astronomers couldn’t agree on the order of the planets from Earth, and Copernicus dealt with this problem at the beginning of the 16th century.

Nicolaus Copernicus and heliocentric theory

Between 1508 and 1514, Nicolaus Copernicus wrote Commentariolus, or “Little Commentary,” a short astronomical treatise that laid the groundwork for his heliocentric system (centered on the sun). During his lifetime, the work was never published. He correctly postulated the relative distances of the known planets, including the Earth, from the sun during the discussion, as well as an estimate of their orbital periods.

How did Copernicus’ Theory Change the World?

Copernicus’ heliocentric theory was far from revolutionary, as it created as many problems as it solved. Heavy objects, for example, have always been assumed to fall to Earth because the Earth is the center of the universe. Why would they do this in a solar-powered system? He maintained the ancient belief that circles ruled the heavens, but his evidence demonstrated that even in a sun-centered universe, planets and stars did not revolve in circular orbits around the sun. Copernicus postponed the publication of his great astronomical work, “De revolutionibus orbium coelestium libri vi”, or “six books on the revolutions of the celestial spheres,” for almost his entire life due to these and other challenges. Completed around 1530, it was not published until 1543 – the year of his death.

How has heliocentric theory affected the world?

How has this affected the world? People’s perception of their place in the universe has been changed forever by the realization that the Earth is not the center of the universe and that other planets and stars do not revolve around it…

How has that changed the world?

Aside from science, the discovery that the Earth is not at the center of everything has caused many people to question the very nature of their existence and religion, earning scientists the Church’s wrath. The Vatican did not repent of its persecution of Galilee until 1992, when Pope John Paul III formally concluded a thirteen-year investigation into the church’s condemnation of the great Italian astronomer.
