Before Nicholas Copernicas was born everyone thought that the Earth was in the middle of the univese, in in the early 1500's he proved them all wrong. Nicholas proved to them that the sun was in the middle and the Earth revolved around it. Nicholas made his prediction sometime between 1507-1515. Nicholas made his dicoveries with a compass.
Nichlas' predictions were rejected by the Cathlic Chuch (where he prepared to work)because they didnt make scence. Before Nicholas was a scientest he studdied paintings and maths, a few years later he made his prediction. Nicolaus Copernicus was a Renaissance mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at its center.
Nicholas' Father died when he was 10 years old so he lived with his mother and brother.
