Yeah, Galileo Galilei did it and was forced to retract it publicly, otherwise..... But they thought the sun orbited the earth....Galileo stated that the earth orbited the sun....
The first person to propose a heliocentric model was the Greek Aristarchus of Samos (c. 270 BCE) who concluded from his mathematical examinations that the Sun was the center of the solar system, although his model was rejected by most astronomers at the time. .However, it was not until the 16th century that a fully predictive mathematical model of a heliocentric system was presented. Nicolaus Copernicus, a Polish mathematician and astronomer, is the man who realized that all the planets orbit around the sun. He got most of that thought from the fact that the ancient Greeks discovered that the Earth was round. It was Copernicus who first published De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres) just before his death in 1543. This work detailed the conjecture that the earth was not at the center of the universe and that the earth and all other planets orbited the sun.Later, Kepler researched more into the subject; he found out that all planets orbit in ellipses and plotted the orbits of the planets.Supporting observations made using a telescope were presented by Galileo Galilei. He was forced to recant his finding under fear of death by the church who believed that the Earth was flat and at the center of the universe. They felt if the Earth rotated around the sun, it was not the center of the universe and this meant that the Earth was just another planet.Later, Newton produced the theory of gravitation and laws of motion that showed that bodies of different mass orbit about ther common centre of gravity. Since the Sun was found to be the most massive body in the Solar System, it had to stay near the centre, pulled out of position only a little by the gravitational forces from the planets. After that is was generally accepted that the Sun is the center.

You're thinking of Galileo; however, the fact that he had to deny, or "abjure," was that the Earth orbited the Sun instead of the other way around. People probably did think of the Earth as the center of the universe, however, the concept of "universe" was nothing like what it is today. Even the term used, "cosmos," meant both "universe" and "world."

Yes it can.
You're probably thinking of Ptolemy, though lots of people presumed the Earth was the center of the cosmos, just as they presumed their city was the center of the world. Today we speak of the "Ptolemaic System" (Geocentric) as though he somehow forced this idea on the rest of the world. Actually, the geocentric model was just one way to account for the observed data. Although we would say today that the heliocentric (Sun in the center) model does that better, since there is no actual center to the universe, it's possible to construct a working model using any point as the center for purposes of calculation.
cupercunicus- Actually it was Galileo
jobAnother Answer:Historically, most all believed the Earth was at the center of the Universe (geocentric) as Aristotle and Ptolemy had taught. But in the 3rd Century B.C., a greek by the name of Aristarchus of Samos proposed the opposite - the Sun at the center of the Universe (heliocentric) but this did not get much support. Then in the 16th Century A.D., a pole by the name of Nicholas Copernicus proved Aristarchus correct. A bit latter, Galileo, using a 'telescope' supported this discovery. Yet, Galileo was forced to recant all by the powerful RC Church.
