The sun travelling around the earth, the moon doing the same and the stars seemed to do the same as well!!
Eudoxus believed that the Earth was the center of the universe, with the stars, planets, and the Sun orbiting around it in perfect circular motion. This geocentric model was later refined and expanded upon by other ancient Greek astronomers.
Ptolemy used observational data gathered by previous astronomers, such as Hipparchus, to develop his geocentric model of the universe. He believed that the Earth was at the center of the universe based on observations that celestial bodies moved in complex patterns in the sky.
Ptolemy's model of the universe was geocentric, but he did not come up with the theory of geocentricity, The theory that the Earth was the center of everything is thought to have come about during the 4th century BC.
Nicolaus Copernicus studied the works of ancient astronomers, particularly those of Ptolemy, whose geocentric model he sought to challenge. He also drew on observations from Islamic scholars, such as Al-Battani, and integrated mathematical principles to develop his heliocentric model, which placed the Sun at the center of the universe. His studies laid the groundwork for the Scientific Revolution and significantly altered the understanding of celestial mechanics.
The term for the center of the universe is often referred to as the "cosmic center" or the "geocentric model" in ancient astronomy. However, in modern cosmology, there is no single defined center of the universe as space is expanding uniformly in all directions from the Big Bang.
it is earth

Eudoxus believed that the Earth was the center of the universe, with the stars, planets, and the Sun orbiting around it in perfect circular motion. This geocentric model was later refined and expanded upon by other ancient Greek astronomers.
Ancient astronomers like Ptolemy believed in a geocentric model, where the Earth was at the center of the universe and all celestial bodies revolved around it. This view was later challenged by Copernicus, who proposed a heliocentric model placing the Sun at the center of the solar system.
geocentric theory
Before the heliocentric model gained acceptance, many ancient astronomers believed in a geocentric universe where the Earth was considered the center of the solar system.
Ptolemy used observational data gathered by previous astronomers, such as Hipparchus, to develop his geocentric model of the universe. He believed that the Earth was at the center of the universe based on observations that celestial bodies moved in complex patterns in the sky.
they believed that the earth was the center.
The concept that Earth is not the center of the universe began to gain traction in the 16th century with the work of astronomers such as Nicolaus Copernicus and later confirmed by Galileo Galilei's observations through a telescope in the early 17th century, which provided evidence to support heliocentrism.
For two or three hundred years, astronomers have had a fair idea the the Sun is not the center of the Universe.
Ptolemy's model of the universe was geocentric, but he did not come up with the theory of geocentricity, The theory that the Earth was the center of everything is thought to have come about during the 4th century BC.
Astronomers believe that black holes exist in the center of every universe. They even think that there may be a black hole in the center of our galaxy, the Milky Way
