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.

∙ 9y agoGalileo was promoting Copernicus's model as the correct model of the planets' orbits, and he used a telescope for the first time to study the night sky.
He made two major discoveries that raised doubts about the ancient geocentric model devised by Ptolemy which placed the Earth at the centre of the universe. These were, first, the moons of Jupiter, which could be seen to orbit round Jupiter and not the Earth, and secondly the phases of Venus.
Venus's phase should always be a crescent according to the Ptolemaic system, but Galileo discovered it sometimes showed a gibbous phase (i.e. more than half), which is impossible in the Ptolemaic system.
Galileo took this as a 'proof' of the heliocentric Copernican system. He was wrong in this because Tycho Brahe had produced an alternative geocentric system that allowed Venus the full range of phases.
Eventually Johannes Kepler produced the modern model, with the Sun at the centre and the planets all in elliptical orbits, and it was later validated by Newton's theoretical discoveries and also by more accurate observations of the planets' positions in the later centuries. So Galileo was eventually proved right about the heliocentric idea - but during his lifetime there was no way of proving it.

Who was Galileo and what did he do How did he prove the heliocentric 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.
What is a sentence for heliocentric?
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.
What happened to Galileo when he tried to prove the heliocentric theory?
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.
What year did Galileo prove the Aristotle theory wrong?
Galileo challenged Aristotle's belief that heavier objects fell faster than lighter ones.
Why was Copernicus' heliocentric theory significant?
The Heliocentric theory was significant because Copernicus had proved something such a long time ago... the fact that it hasn't been proven wrong, or the fact that no-one else believed him because they didnt have the technology to prove it back then.

How did Galileo help prove that Copernicus' theory about the solar system was right?
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.
What invention used by Galileo helped prove Copernicus theory that the earth revolves around the sun?
The astronomical telescope.
How was the copernican theory proven correct?
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.
What method did Galileo use to prove his theory?
He used the pooping theory, allied with thought and intelligence. Oh, and he paid attention to his studies and read his books properly.
How did Copernicus prove that the earth wasn't in the middle of the universe?
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).
Why did catholic church oppose galileos heliocentric model of the universe?
The charge was ignoring the implications of the Copernican theory. Previously the Inquisition had asked him not to teach Copernicus' theory as anything but a hypothesis (which it was at the time). In 1632 he was asked to come to Rome to answer for alleged breaching the contract with the Inquisition. Recently, scholarship has shown that the document on which Galileo's trial was based was a forgery planted in the Roman Curia by an unscrupulous official. In 1979, Pope John Paul II called for the formal exoneration of Galileo. For a more complete discussion and references please get the book Seven Lies about Catholic History.See related link below.AnswerAt the time the heliocentric model was still a theory and had not yet been proven. Many Church leaders agreed that Galileo was probably correct. However, he was teaching a theory as fact when it had not yet been proven as such. This is very analogous to the evolutionary theory today that causes so much disagreement and division. The Church agrees that evolution probably occurred but the theory has not yet been proven beyond a shadow of a doubt.AnswerGalileo's model was a theory and he taught it as fact when, in fact, there was no proof at the time.AnswerActually, Galileo had a large following among the Roman Curia, including the pope. However, Galileo got himself into trouble by teaching that the heliocentric (Sun-centered universe) theory was fact. However, at the time it was just a theory or hypothesis and Galileo even stated that he could not prove it. Had he changed his approach to the subject we never would have heard today of the controversy. Unfortunately, Galileo was not a humble person and had quite a temper and sarcastic manner and began to attack the Church in speech and his writing. Even his close friend the pope became the target of his rage. Of course, this did not endear him to the Church and he lost much of his standing with the Roman clergy.AnswerGeocentric theories kept mankind, the deity's highest creation, at the center of the universe. Heliocentric theories displaced mankind from that position. This thought was abhorrent to the church. AnswerI don't think the Church was threatened by Galileo's observations. The Church had issues with Galileo's not complying with its restrictions on his teaching which, at that time, was only an unproved theory.
