Which model suggests that the Earth is at the center of the universe?

The model that places the Earth at the center of the universe is known as Geocentrism. This ancient astronomical paradigm posits that all celestial bodies, including the sun, moon, and stars, revolve around Earth. This worldview was prevalent before the Copernican Revolution, which introduced the heliocentric model, where the sun is at the center of the solar system.

Geocentrism held sway for centuries, largely due to the philosophical and theological beliefs of the time, which emphasized humanity's central place in the universe. The model was supported by notable astronomers like Claudius Ptolemy, who developed detailed epicycles to explain the observed motions of the planets around a stationary Earth.

Other options, such as heliocentrism, present a contrasting perspective, where the sun is recognized as the core of our solar system. Cosmology refers to the scientific study of the universe's origin, evolution, and eventual fate, rather than a specific model of planetary motion. Astronomy encompasses the broader scientific field studying celestial objects, which includes multiple models of the universe but does not specify a single one as being centered on Earth.
