The Greek philosopher Aristarchus of Samos is credited with first questioning the geocentric theory in the 3rd century BC. He proposed a heliocentric model in which the Earth and other planets revolve around the Sun.
The concept of geocentrism, which posits that the Earth is the center of the universe with celestial bodies orbiting around it, was widely held by ancient astronomers and philosophers such as Aristotle and Ptolemy. However, it was the Greek philosopher Claudius Ptolemy who developed the most influential geocentric model of the universe in his work "Almagest" in the 2nd century CE.
The Ptolemaic universe theory was proposed by the ancient Greek astronomer Claudius Ptolemy in the 2nd century AD. He proposed a geocentric model of the universe with Earth at the center, and this theory dominated Western astronomy for over a thousand years.
Brane theory is not a cosmological model but a theoretical framework in theoretical physics that suggests the existence of additional dimensions beyond the known four dimensions (three of space and one of time). It is not related to the geocentric or heliocentric nature of the solar system.
Aristotle believed in a geocentric model, with Earth at the center of the universe. Ptolemy further developed this idea with his geocentric model that included epicycles to explain planetary motion. Copernicus proposed a heliocentric model, with the Sun at the center of the solar system, challenging the geocentric view. Galileo's observations with a telescope provided evidence to support Copernicus's heliocentric model, leading to the acceptance of the heliocentric theory over the geocentric view.
geocentric theory originated with the man named Aristotle.
Plato and his student Aristotle believed in the geocentric theory. It was the ruling explanation model about how our solar system was put together for several hundreds of years.

A few celestial objects appear to have retrograde motion.
Aristotle first thought that the Earth was the center of the solar system. Ptolemy was the second one to think of the theory.
The geocentric Solar system theory was first proposed by ancient Greek philosopher Aristotle and further developed by astronomer Claudius Ptolemy. This theory placed Earth at the center of the universe with all celestial bodies, including the Sun, planets, and stars, orbiting around it.
The idea of elliptical orbits in the geocentric theory was introduced by the ancient Greek astronomer Claudius Ptolemy, who proposed a complex system of epicycles and deferents to explain the observed motion of celestial bodies.
Aristotle believed in a geocentric model of the universe, with Earth at the center and celestial bodies orbiting around it in concentric spheres. He also theorized that the universe was eternal and unchanging.
Aristotle believed in a geocentric model of the universe because it aligned with his concept of natural motion, where he believed that the Earth was the center of the universe and that celestial bodies moved in uniform circular motion around it. This perspective was also supported by observations of apparent motion of celestial bodies in the sky.
