The Revolutionary Ideas of Copernicus. Nicolaus Copernicus (1473-1543) developed a heliocentric model of the universe and in the process initiated the Scientific Revolution. In his model, Copernicus maintained that Earth was not the center of the universe.
Copernicus died the same year his book was published. After 1,400 years, Copernicus was the first to propose a theory which differed from Ptolemy's geocentric system, according to which the earth is at rest in the center with the rest of the planets revolving around it. he word helios in Greek means sun.. Heliocentric means that the sun is at the center. A heliocentric system is one in which the planets revolve around a fixed sun. Thus Mercury, Venus, the Earth, Mars, Jupiter and Saturn all revolve around the sun.
