Question

How has Ptolemy’s theory been disproved today?

Answer 1

Ptolemy's theory of a geocentric universe, which placed the Earth at the center of the universe and all other celestial bodies in orbit around it, has been disproved by modern astronomy. This is due to the discovery of the heliocentric model, which places the Sun at the center of the universe and all other celestial bodies in orbit around it. This model was first proposed by Nicolaus Copernicus in the 16th century and has since been supported by a variety of scientific evidence.
