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.
While radically different from Ptolemy's model, Copernicus's heliocentric theory was hardly an original idea. Similar theories had been proposed by Aristarchus as early as the third century B. C., and Nicholas de Cusa, a German scholar, had independently made the same assertion in a book he published in 1440.
