Nicolaus Copernicus < NOVA NET ANSWER
that the world was heliocentric not geocentric aka sun centered universe and earth centered universe
The word for earth-centered is geocentric,
Galileo and Copernicus were two of the scientists to disprove Ptolemy's geocentric theory of the universe. The Ptolemaic theory stated that the center was earth.
The first scientist to dispute Ptolemy's geocentric model was Nicolaus Copernicus. In the early 16th century, Copernicus proposed a heliocentric model, placing the Sun at the center of the universe and suggesting that the Earth and other planets revolve around it. His work, particularly the publication of "De revolutionibus orbium coelestium" in 1543, laid the groundwork for the Scientific Revolution and fundamentally changed our understanding of the cosmos.
Ptolemy's biggest discovery was his geocentric model of the universe, which believed that the Earth was at the center of the universe with planets and stars moving around it in circular orbits. This model dominated Western astronomy for over a thousand years.
The universe is not geocentric - it has no center. Only Luna is geocentric.
A geocentric theory is one that states the universe is centered by Earth. Geo means earth. The old Ptolemaic Model of the universe has earth as the center. A heliocentric theory is one that is centered by a source of heat. Helio = heat. It basically states that the sun is the center of our galaxy. (Copernican Model)
The earth-centered model created by Ptolemy is called the Ptolemaic model or geocentric model. It proposed that the Earth was the center of the universe, with all celestial bodies moving around it in circular orbits.
