Nicolaus Copernicus < NOVA NET ANSWER
The Ptolemaic Model followed a geocentric model of the solar system. This was then challenged by Nicolaus Copernicus, who claimed a heliocentric model which sparked an integral part of the Scientific Revolution called, the Copernican Revolution. Copernicus' proposal was followed by the Tychonic Model, with attempted to compromise with the geo- and heliocentric models. Then, Kepler improved by suggesting elliptical orbits. The Copernican Revolution came to a close with further speculation from Galileo Galilei and Isaac Newton TL;DR Because they were wrong
The Ptolemaic system has Venus travelling between Earth and Sun. Copernicus's theory has both the Earth and Venus going round the Sun although Venus is in a smaller orbit than the Earth. That makes it an inferior planet, which goes through inferior conjunction once in every synodic period, at which time it is liable to transit across the Sun's disk, as last happened in 2012. When Venus is close to passing between us and the Sun it appears as a crescent, like a crescent moon, and this is predicted by both the Geocentric and the Heliocentric theories. The main geocentric theory fails to predict Venus's gibbous phase when it is on the opposite side of the Sun. However this does not prove the heliocentric theory because Tycho Brahe's system predicts the gibbous phase for Venus yet it still has the Earth at the centre. The heliocentric theory was finally accepted long after the time of Copernicus, Tycho and even Galileo, when further scientific discoveries by Kepler and Newton, and others, made its acceptance inevitable.
What he withdrew was his insistence that the heliocentric theory represented the absolute truth. He did that when challenged by the Vatican to come up with a demonstration that it was true, which he could not do. However after Galileo's lifetime further discoveries were made that showed that the heliocentric theory was better than the other possible theories and it is now generally accepted.
Copernicus used early trigonometry to show that the observations of the movements of the planets in the sky are most easily explained by assuming that the Earth and other planets orbited around the Sun. He published this in 1543 in Poland. Copernicus also made contributions to Mathematics.It had previously been assumed that the Earth was the centre of the universe and that all other bodies revolved around the Earth. This appeared obvious to ancient astronomers since the heavenly bodies all rose in the East and set in the West. The planets (wanderers) altered their places in the sky relative to other bodies and this was explained by assuming that their motions executed circles within circles. However, in order to fit observations, this had to be carried to a ridiculous extreme.The theory that all other bodies revolved around the Earth had become part of religious dogma, so was vehemently opposed by the church.Copernicus's doctrine was opposed by the church for many years. In 1616 the Catholic church declared that it was contrary to the scriptures. Galileo had been a champion of Copernicus in Italy and was forced to recant and spent the rest of his life (1564-1642) under house arrest by order of the inquisition.He proposed a heliocentric system that Earth orbits the sun. apex cx

The first astronomer to dispute the model seriously was Nicholas Copernicus in the 1500s. His model used circles and epicycles, like the old Ptolemaic model, but had the Sun at the centre, which led to its being named the heliocentric model. Sixty years after his death in 1543, the Copernicus model was taken up by Galielo in his dispute with the Catholic church. In the latter half of the 1600s further discoveries led to wider acceptance of the heliocentric concept. However the rest of the Copernicus model was discarded and replaced by Kepler's model which had each planet in an elliptical orbit, and this was taken up and given scientific credibility by the discoveries of Newton and others.

Our notion of space has changed over time due to advancements in science, technology, and philosophy. From the geocentric view prevalent in ancient times to the heliocentric model proposed by Copernicus, our understanding of space has evolved as new discoveries have been made. Additionally, theories like general relativity and quantum mechanics have further shaped our perception of space as a dynamic and interconnected fabric.
