Copernicus

Several reasons, but here's a few:

1) It offered no advantage over Ptolemy's orbits. Predicting planetary motion with one or the other was about the same.

2) It did not make "sense" that such a large object as our Earth could be kept in motion. The motions of other bodies was acceptable because (it was thought) they moved in the aether, and thus could continue to move forever.

3) We on Earth did not feel any motion.

4) If our Earth moved around our Sun, then we should see some change in the position of the stars in relation to our Sun -- but we don't. Indeed, the first record of detecting such a change was not until 1823.

5) Artistic and phenomenological descriptions of our Earth in the Bible indicated that it stood still.

Tycho Brahe was the most brilliant astronomer of his time, but he rejected heliocentrism based on #4.

Because it was the old catholic churches teachings.

you have been trolled! xD

Copernicus believed that the Sun was at the center of the universe, not the earth. It's very conter-intuitive, but he realized that such a model would best fit the way that the planets behaved. Unfortunately, he also believed that the planets rotated around the Sun in perfect circles. Thus, his theory didn't work any better than the Earth-centric models. It was only when Kepler proposed that the planets moved in elipses around the Sun that we finally had a model that could accurately predict the motions of the planets. Copernicus laid the groundwork and Kepler (and many others) finished what he'd started.

He taught people how to talk in English and write in Hebrew.

he was arrested by the church

Contrary to most people of the 14th Century, Copernicus believed that the Earth revolved around the sun. Galileo later proved Copernicus' theory to be correct.

The Heliocentric Theory.

- which is the idea that the stars, the earth, and the other planets revolve

around the sun.

We know very little what events Nicolae Copernicus viewed as "struggles," as he never wrote much about his inner thoughts. We can only speculate.

Amongst events that may have made his life difficult for Nicolae:

1) His father died when he was 10. His maternal uncle then became his benefactor and major employer.

2) When Nicolae uncle attempted to have him installed in a church post, the order (for reasons still unknown) refused. Nicolae then went to Rome to study canon law.

3) It took him seven years to get a degree while in Italy, indicating a lack of devotion to study in that specific field. Again, we don't know the details.

4) During the time he was an adminstrative assistant to his uncle, the city of Warmia was often under attack from Teutonic Knights.

5) Despite urgings from his friends and co-workers, Nicolae refused to publish his heliocentric ideas, fearing attacks for "the novelty and incomprehensibility of his theses."

Geocentric theory

Copernicus produced a new theory published in 1543 that had the Sun at the centre but in other respects it was similar to the Ptolemaic theory with its circles and epicycles.

He thought his model was simpler because many of the epicycles were smaller, even though there were just as many as in the Ptolemaic theory. We now know that this is because the Ptolemaic theory with the Earth at the centre required larger epicycles to 'take out' the Earth's motion round the Sun. In other words in the Ptolemaic model the Sun's orbit was the 'reverse' of the Earth's orbit. To that extent the Copernican theory was simpler.

Kepler's theory of 1609 did away with all the old circles and replaced them all with elliptical orbits for the planets, each one in its own plane, close to the ecliptic. He retained the idea that the Sun is at the centre, and devised the Three Laws of planetary motion.

After a full dynamical theory was produced by Newton that explained the elliptical orbits and Kepler's Laws, more and more people accepted that it was right, and that is the situation today, with tiny corrections due to Einstein's General Theory of Relativity.

Kepler formulated laws of planetary motion, while Copernicus merely(!) proposed that the sun was the center of the solar system rather than the earth.

Analice Nicolau was born on September 6, 1977, in Blumenau, Santa Catarina, Brazil.

While many say it was capernicus I think it was actually " Aristarchus" a couple hundred years before Capernicus.

If you were European, Europe.

they proved that the earth rotate around the sun not the other way making people doudt the ancient greek authorities

A geocentric theory is one that states the universe is centered by Earth. Geo means earth. The old Ptolemaic Model of the universe has earth as the center.

A heliocentric theory is one that is centered by a source of heat. Helio = heat. It basically states that the sun is the center of our galaxy. (Copernican Model)

He was Prussian, and at that time Prussia was a part of Poland.

That science was a process of changing ideas

Nicolas Copernicus did not use a telescope, the use of the telescope to study the solar system was not done until over 50 years later by Galileo.

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.

He knew about 6 planets. See the related link for further information.
