Our Universe today is MUCH bigger than Copernicus could have imagined. In the first place, their idea was that our galaxy was the universe, and had no idea that many of those stars they wondered about were actually galaxies much like our own, including some vastly larger. The next major advance was the invention of the telescope followed by Galileo's creative studies with that, and that was when they began to realize that ours was not the only planet in the Universe.
They believed in a heliocentric universe. This meaning that the earth was not the center of the universe, but that the sun was. However, many people , including the church, did not agree with this theory. Instead they believed in a geocentric universe. Plato and Aristotle believed in this theory.
The heliocentric theory was devised by Nicolaus Copernicus, a Polish mathematician and astronomer who proposed that the Sun, not the Earth, was the center of the universe. His work laid the foundation for the Copernican Revolution and modern astronomy.
Nicolaus Copernicus proposed the heliocentric theory, which stated that the Earth and other planets revolve around the Sun. This challenged the prevailing geocentric model that placed Earth at the center of the universe. Copernicus's theory laid the foundation for modern astronomy and our understanding of the solar system.
Answer: -Ptolemy
Claudius Ptolemy and Nicolaus Copernicus both described the universe. Ptolemy, a Greek astronomer, wrote a book that combined all knowledge of astronomy that he could find. He expanded ancient theories with careful mathematical calculations in what was called the Ptolemaic Theory. Ptolemy thought the Earth was the center of the Universe and that the sun and other planets revolved around Earth. Although this theory was incorrect as we now know, it predicted motions of the planets better than any other theory at the time did. Copernicus, a Polish astronomer, published a new theory that would eventually revolutionize astronomy. Copernicus thought the Sun was the center of the universe, and all the planets (including Earth) orbit the sun. Although Copernicus correctly thought that the planets orbit the sun, his theory did not replace Ptolemaic theory immediately. When Copernicus's theory was accepted, major changes in science and society called the Copernican revolution took place.
Nicolaus Copernicus
Copernicus' theory was that Earth is not the center of the universe and we revolve around the Sun.
Copernicus' theory was that Earth is not the center of the universe and we revolve around the Sun.
Copernicus

The heliocentric theory is the theory that the sun is the center of the universe, not the earth.
Nicolaus Copernicus disagreed with his theory, Copernicus belived that Ptolemy's view was to complicated.
Nicholaus Copernicus was one of the first to challenge the theory that the earth was the center of the universe. He made up the Heliocentric theory.
He discovered the revolutionary theory about the sun.
He worked on his theory for years, but it was only published in the year of his death, in 1543.
He was a Polish mathematician who disagreed with Ptolemy's view that the earth is the center of the universe. The heliocentric theory is the theory that the sun is the center of the universe, not the earth.
