Heliocentric means having the Sun as the center, such as in the heliocentric model of the solar system where the planets orbit around the Sun. This model replaced the geocentric model, in which Earth was believed to be the center of the universe.
Copernicus proposed a heliocentric model, where the Earth and other planets revolve around the Sun, while Ptolemy's model was geocentric, with Earth at the center of the universe. Copernicus' model challenged the prevailing belief that Earth was the center of the universe and laid the foundation for modern astronomy.
he said the earth was the center of the universe and everything revolves around it
The first scientist to say the earth is not the centre of the whole universe was Nicolaus Copernicus early in the sixteenth century.
Copernicus and Galileo were two key figures in the history of science who argued that the Earth is not the center of the universe, but rather orbits around the Sun. This heliocentric model challenged the long-held belief in geocentrism, where Earth was considered the center of the universe.
Ptolemy.
He said that sun was the center of the universe and that the earth and all the other planets orbit around it.
Pretty sure it was Ptolemy.
