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.
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.
Answer: -Ptolemy
Copernicus.
The big bang theory is the explosion that started the universe. Where as the big crunch is the theory where the universe will eventually contract and become increasingly clumped and eventaully all mater would collapse into black holes which would then coalesce producing a unified black hole or Big Crunch singularity.
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 proved that earth is the center of the universe
Copernicus
1543
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.
Heliocentric theory of universe.
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.
Ptolemy created the geocentric theory of the universe and Nicolous Copernicus created the heliocentric theory of the universe.
