There is no doubt that Copernicus, who was born in Poland, was great scientist. In his twenty, he began observations of the sun, the moon and the planets use mathematical calculations. What shocked him was which he found the earth wasn’t the centre of the solar system. Only that the sun was the centre instead of the earth did the movements of the other planets made sense. Therefore, he kept this discovery as a secret until he felt it was complete in 1514, when he only showed it secret to his friends. While his friends encouraged him to publish his idea, Copernicus was cautious enough not to get it publishing until he was dying in 1543. Why didn’t he show his scientific idea to the world the moment he discovered it? The Christian Church was to be blame for it.
