The geocentric theory was held not just before 1543, but before the 1600s. It was a scientific belief and a theory that stated the Earth was the center of the universe and that everything else was held in orbit around it.
Plato's Theory of Astronomical Convulsion
Planet Earth was held to be the centre of the Universe and everything else in the sky was held to revolve around Earth.

Aristotle if thats how you spell it :)
Nicolaus Copernicus was a Polish astronomer who proposed the heliocentric model of the universe, with the Earth revolving around the Sun. His theory challenged the commonly held belief of a geocentric universe and laid the foundations for modern astronomy. Copernicus's work was published in his book "De revolutionibus orbium coelestium" (On the Revolutions of the Celestial Spheres) in 1543.
Aristotle if thats how you spell it :)
Aristotle's theory of the universe, which believed in a geocentric model with Earth as the center of the universe, was held as law for thousands of years despite being incorrect. His ideas were widely accepted and influential in shaping Western thought until the heliocentric model proposed by Copernicus and later supported by Galileo challenged this view.
