the old geocentric theory that the Sun goes round the Earth
Did You Know?
The idea that the Earth is the center of the universe and that the sun revolves around it is an ancient one, probably dating back to the earliest humans. Not until 1543 did the Polish astronomer Copernicus publish his calculations proving that the Earth actually revolves around the sun, thus replacing the geocentric model with a heliocentric model (from Helios, the Greek god of the sun). But geocentrism remains central to various religious sects around the world, and still today one in five adult Americans believes the sun revolves around the Earth.
