3. The Earth and the Sun
Although most ancient Greek philosophers considered the Earth to be flat, Eratosthenes calculated that it was a sphere and worked out its circumference around 240 BC. Considering that he used only rough estimates, his calculation is surprisingly accurate. As it seemed obvious that the Sun moved in the sky and the Earth stood still, this was the basis of astronomy until the work of Copernicus in the 16th century. Once Copernicus's work was published in 1543, it became increasingly difficult for scientists to see the universe in the way they had done before with the Earth at the centre of the universe. However, the theory was so controversial for religious reasons that it didn't become widely known. When Galileo came to the same conclusions as Copernicus in 1610, he was accused of heresy by the Church and imprisoned, in case his view of the universe encouraged people to doubt the existence of God.
