Bruno did a pretty good job of it, and was burned at the stake for his troubles. Galileo's observations of the solar system were very thorough, and he had a decent telescope with which to record his findings. The evidence Galileo gathered was quite compelling.
The geocentric theory arose from observations and contemplation of the assumed perfect nature of the circle. It was never proved. (It would have been exceedingly difficult to prove it, since it turns out it's wrong.)
The heliocentric theory gained authority from the 1500's because it explained the observations better and with more simple geometry (once you realize that the ellipse is as "perfect" as a circle.
No, because he stated that the sun is at the center of the universe, but we have discovered that the universe is expanding.
I think the main error in the theory was the fact that Copernicus believed that
orbits must be circular.
Copernican's theory was proven by Sir Isaac newton when he came up with his theory of gravity. Some say that his theory was proven earlier by Galileo Galilei.
That the earth was not the center of it.
Heliocentric was the one.

There are no fundamental laws behind the Copernican theory. The three laws of planetary motion that we use now were discovered by Johannes Kepler and published in 1609, sixty-six years after Copernicus died. Kepler introduced the new idea of elliptical orbits. The idea that the Sun is at the centre (loosely speaking) was the only part of the Copernican theory that Kepler retained.
Nicholaus Copernicus, a German/Polish astronomer and mathematician, developed the Copernican Theory, a revolutionary idea which changed our understanding of the universe and how it rotates and progresses. He developed the idea of Heliocentrism, then a theory, now a fact, that the the sun, not the earth, is the center of the universe with all the planets revolving around it. His book, De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres) was finished in 1532, however, because of Copernicus' fear of rejection from the Church and his peers, the book was not published until 1543, shortly before his death.
You have answered this question for yourself. It was 'Nicolas Copernicus' , hencethe word 'copernican'.
Because it was supported by observations.
A Theory is unproven, but Laws are proven. Theory becomes law after that theory is proven correct.
In science, a theory is, by definition, proven and accepted as fact.

The Ptolemaic theory (geocentric) put forth by Claudius Ptolemy (100-170 AD) was based partly on the work of Aristotle. It was replaced by the Copernican theory (heliocentric) beginning around 1400 AD.
When a hypothesis is proven, it is no longer a hypothesis; a proven hypothesis is a theory.
A theory is never truly "proven" correct; data can be found time and time again that supports a hypothesis, which may then become a theory, but a theory doesn't really graduate to something else if it "seems" correct. Theories are always being modified as new advancements are made. "Law" (like the law of gravity) is a dated term that essentially equates to a theory in modern science.
No. It's never correct to say that anything is "only" a theory or "just" a theory or"merely" a theory or "nothing but" a theory or an "unproven" theory.A theory can never be proven, but it can be dis-proven in two seconds. If a theoryhas been around for three hundred years and it hasn't been dis-proven yet, thenthat's a pretty good indication that you can trust the statement it makes.
The heliocentric 'theory' is not really a theory at all, more an assertion that the Sun is at the centre of the solar system. Copernicus's theory assumes that the Sun is at the centre and provides a model of the planets' orbits that uses circles and epicycles to explain the observed orbits. He said it was simpler than the old "geocentric" (Earth centred) Ptolemaic system, but it was not really, it actually had more epicycles. Note: Perhaps the questioner got mixed up. The Copernican theory IS a heliocentric theory. Perhaps the question is about the geocentric theory and the Copernican theory. Anyway, Kepler simplified the heliocentric theory and now we know that his model is correct.
The Ptolemaic theory and the Copernican Theory
He went against the Aristotelian theory and he defended the Copernican theory.
A scientific theory is an idea that is supported by a hypothesis. Once the theory is proven to be permanently correct, it is a law or fact.
