The universe is not geocentric - it has no center. Only Luna is geocentric.
Aristotle supported the geocentric model, which placed Earth at the center of the universe. He did not propose a heliocentric model with the Sun at the center. It was later astronomers like Copernicus who challenged the geocentric model in favor of a heliocentric one.
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 geocentric modelof the universe stated that the earth was at the centre of the universe.

Nicolaus Copernicus challenged the geocentric theory and presented the heliocentric theory. The heliocentric system placed the sun at the center of the universe.
Galileo's work caused controversy because it challenged the accepted geocentric model of the universe, which placed Earth at the center. His support for the heliocentric model, with the sun at the center, contradicted religious teachings of the time. This led to conflicts with the Catholic Church and Galileo being condemned for heresy.
Nicolaus Copernicus, Galileo Galilei, and Johannes Kepler were prominent scientists who challenged the Earth-centered view of the universe, known as the geocentric model. Copernicus proposed the heliocentric model, where the Earth and other planets orbit around the Sun. Galileo's observations with the telescope provided evidence for this heliocentric model, while Kepler refined it by discovering that planets move in elliptical orbits around the Sun.
Ptolemy

Only scientists and astronomers believed in the heliocentric theory, and some of them would be excommunicated or almost executed if they weren't geocentric.
