Copernicus proposed a heliocentric model with the sun at the center of the solar system, while Galileo supported this idea with observational evidence through his use of the telescope. Galileo's observations also challenged the geocentric model supported by the Catholic Church at the time.
How did Ptolemy prove his model?
Galileo explained the backwatds motion of the planets
Who discovered heliocentric cosmology?
Nicolaus Copernicus The above answer is incorrect. Copernicus only proved what Aristarchus already discovered, however at that time people rejected his theory since Aristotle was more popular in terms of science than he was. "He presented the first known heliocentric model of the solar system, placing the Sun, not the Earth, at the center of the known universe...The heliocentric theory was successfully revived nearly 1800 years later by Copernicus" Aristarchus is the correct answer
