He said he had proof of the heliocentric idea, but refused to reveal it, saying that the cardinals were too stupid to understand it. But later in court he could not produce adequte proof and recanted.
However long after Galileo's death further scientific discoveries forced people to realise that the Sun is at the centre after all. In Galileo's time it was only speculation, not a scientific theory.
He was an Italian scientist of the 17th century. He did not prove the heliocentric theory. But everyone accepts the heliocentric principle now, after it was proved right; but that happened long after Galileo's time, after new scientific discoveries in the latter half of the 1600s.
Ptolemy thought that the Earth was the center of solar system and most people believed this theory. But Copernicus thought that the Sun was the center of solar system and most people didn't believed this theory. Who was right? Copernicus was right because later Galileo prove that if the Earth was at the center then he couldn't see the phases of Venus. Sentences for heliocentric. Galileo proved that the Copernicus's theory which was heliocentric was right.
He was not successful, despite mounting an elaborate propaganda campaign against the church. Galileo himself had earlier spoken in favour of the geocentric theory on the grounds that no movement could be seen in nearby stars as the Earth supposedly orbited round the Sun. This was a big obstacle to the full acceptance of the heliocentric theory until the 19th century, when Bessel measured the small movement of the nearby star 61 Cygni. Thus there was movement after all, called parallax, but it was just too minute to be observed until 1838, 200 years after Galileo's time.
Galileo challenged Aristotle's belief that heavier objects fell faster than lighter ones.
He didn't know it, he just brought out a new theory that showed that with the Sun at the centre the planets' paths could be explained more simply. That was in 1543 and Kepler produced another heliocentric theory in 1609 which had the planets moving in elliptical orbits round the Sun. The only thing in favour of Kepler's theory at the time was that it explained the planets' positions more accurately than previous theories. But 80-90 years later Newton's discoveries in gravity and the laws of motion were used to prove by theory that the planets must move in elliptical orbits.

Newton explained his theory
Galileo Galilei used his telescope to provide crucial evidence supporting the heliocentric theory, which posits that the Earth and other planets orbit the Sun. His observations of celestial bodies, such as the phases of Venus and the moons of Jupiter, challenged the geocentric model and helped establish the validity of Copernicus's earlier work. Galileo's findings were significant in advancing the scientific revolution and changing our understanding of the cosmos.

The astronomical telescope.
He used the pooping theory, allied with thought and intelligence. Oh, and he paid attention to his studies and read his books properly.
Galileo did not prove that Earth was not flat (It had already been agreed that it was round). Galileo invented the telescope and used it to prove that there were objects which did not orbit the Earth, supporting Copernicus' Heliocentric model for the universe. The Earth was known to be round by the ancient Greeks, but I do not who it found out initially (sorry).
Galileo's invention of the telescope helped him observe the phases of Venus, the moons of Jupiter, and sunspots, which provided evidence for the heliocentric model proposed by Copernicus. These observations challenged the geocentric view of the universe and supported the idea that the Earth revolves around the Sun.
Bruno did a pretty good job of it, and was burned at the stake for his troubles. Galileo's observations of the solar system were very thorough, and he had a decent telescope with which to record his findings. The evidence Galileo gathered was quite compelling.
