The sun-centered theory of the universe, known as heliocentrism, was primarily developed by the Polish astronomer Nicolaus Copernicus in the 16th century. His groundbreaking work, "De revolutionibus orbium coelestium" (On the Revolutions of the Celestial Spheres), proposed that the Earth and other planets orbit the Sun, challenging the long-held geocentric view that placed the Earth at the center of the universe. Copernicus's theory laid the foundation for modern astronomy and significantly influenced later scientists, including Galileo Galilei and Johannes Kepler.

the heliocentric theory is the theory that the sun is in the center of the universe. the geocentric theory is the theory that the earth is in the center of the universeGeocentric models had the earth as the center of the universe with the sun and all the planets orbiting it. Heliocentric models (the current accepted ones) have the sun as the center, with the earth and planets orbiting it.Geocentric was the idea developed by the Greek philosopher Aristotle of an earth-centered view of the solar system. With Christianity's influence, people had thought that God put Earth in the center of the universe. Heliocentric came later on by Italian astronomer Galileo that the sun was put at the center of the solar system while Earth and all the other planets orbit around it.
The heliocentric theory was originated by Copernicus.
that the world was heliocentric not geocentric aka sun centered universe and earth centered universe

No! It is heliocentric, or sun centered.
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)

Copernican challenges beliefs by claiming sun-centered universe
This was part of a theory developed by Claudius Ptolemy, a Greek living in Alexandria, Egypt in the second century AD, to explain the movements of the sun, planets and stars.
Copernicus
Galileo's most significant observation and discovery was that the universe (or now the solar system) was Sun-Centered. Originally, people accepted the Copernican theory that the universe was Earth-centered. For a few years Galileo had to defend his discover until 1616.
well this theory was that the sun was a princaple source of motive power in the universe
