It took two centuries for the Copernican model to replaced the Ptolemaic model because?
The short answer: when people's world views are challenged in such a manner that contradicts a previously affirmed belief system, they have difficulty accepting the significant change. There was much resistance to the idea of the sun being the centre of the universe as opposed to the earth. [Insert a great deal of study of Western History, Science and Religion here]
What else can I help you with?
Why did the Copernican hypothesis with gradual acceptance?
Because it was supported by observations.
Why do scientists not accept the ptolemaic model?
The Ptolemaic model is also known as the geocentric model, where the Earth is at the center of the solar system. Scientists refute this because orbital paths show that the solar system is heliocentric.
What were three of Tycho Brahe's reasons for believing his model was right?
Tycho Brahe produced a prodigious volume of measurements and observations, but he didn't fabricate or hypothesize any particular model, and didn't try to convince anybody of anything.
What showed Ptolemy's model for the universe was incomplete?
The geocentric system of Ptolemy said that all the planets stay in their prescribed spheres. By that was meant that each planet has its own shell (a hollow sphere) that it stays inside. The sphere of Mercury is closest to the Earth, then Venus and then the Sun. Galileo discovered the phases of Venus with his telescope. Now it's quite OK for Venus to have a crescent phase in the Ptolemaic system, because it can travel between the Earth and the Sun. But Galileo also saw that Venus had a gibbous phase at certain times, which the Ptolemaic system fails to account for. Galileo said this was a serious fault with the Ptolemaic system (correct) but he then claimed incorrectly that this must prove that the Copernican system - with the Sun at the centre - is correct. Galileo was wrong about that because Tycho Brahe came up with an alternative model that had Mercury and Venus orbiting the Sun, but then the Sun and the other planets still orbited round the Earth. This was a geocentric system that correctly described all the phases of Venus. But after the work of Kepler and Newton it was eventually agreed generally that the Sun has to be at the centre.
How did Galileos observation of Jupiter and venus support Copernicus' model?
Galileo's discoveries with the telescope sowed doubts about the ancient Ptolemaic model which had the Earth at the centre. First, Jupiter's moons orbited round Jupiter and not the Earth, the first objects that had been discovered that were not orbiting the Earth. Secondly the discovery of the phases of Venus raised doubt about the Ptolemaic model, particularly the gibbous phase when, we now know, Venus is round behind the Sun as seen from Earth. In the Ptolemaic model Venus never goes behindthe Sun (as seen from Earth) and the gibbous phase cannot happen.By implying in the title of his book 'Dialogue of the two world systems' that there were only two models in contention, those of Ptolemy and Copernicus, Galielo insinuated that if the Ptolemaic model was incorrect the Copernican system must be correct. This was logically flawed because at the time there were two other systems in the public domain that both explained Venus's phases. These were the models of Tycho, which was geocentric, and finally Kepler's which was heliocentric.Of these four, Kepler's was eventually accepted by everyone after Newton's theoretical discoveries showed that Kepler's elliptical orbits for the planets agreed with the new theory of dynamics.
Why models of the ealry ptolemy solar system were replaced by the copernican model?
The early Ptolemaic model placed Earth at the center of the solar system, which led to complex explanations for retrograde motion of planets. The Copernican model shifted the center to the Sun, providing a simpler explanation for planetary movements. Additionally, the Copernican model was supported by observational evidence and eventually gained wider acceptance due to its better predictive power.
How was Copernican model was an immediate improvement from Ptolemaic?
It was not an immediate improvement and actually it used more epicycles than the Ptolemaic mode so was more complicated. But the idea that the Sun is at the centre was taken up by Kepler in his studies of planets' orbits that led to the laws of planetary motion and eventually to the dynamic model of the solar system devised by Newton and others, which is the generally accepted model at the present time.
Why did the Copernican hypothesis with gradual acceptance?
Because it was supported by observations.
What is important about the copernican revolution?
Part of why the Copernican revolution was so important is because it changed how people viewed the word. Before Copernicus, they believed in Ptolemy, who thought that the earth was flat.
How did Nickolaus Copernicus account for the retrograde motion of the planets?
The retrograde motion of the planets is well modelled by both the Ptolemaic system and the Copernican system, and by the other models. But the Copernican system explains it more simply because, for example, Mars's retrograde motion is caused simply when Mars is overtaken by the Earth, which goes more quickly round the Sun. Thus an observer on the Earth sees Mars appearing to go 'backwards' on the ecliptic around the time of closest approach (opposition). This can be easily demonstrated by assuming simple circular orbits.
Why did nicolaus Copernicus thought the sun was the center?
Copernicus produced a new theory published in 1543 that had the Sun at the centre but in other respects it was similar to the Ptolemaic theory with its circles and epicycles. He thought his model was simpler because many of the epicycles were smaller, even though there were just as many as in the Ptolemaic theory. We now know that this is because the Ptolemaic theory with the Earth at the centre required larger epicycles to 'take out' the Earth's motion round the Sun. In other words in the Ptolemaic model the Sun's orbit was the 'reverse' of the Earth's orbit. To that extent the Copernican theory was simpler. Kepler's theory of 1609 did away with all the old circles and replaced them all with elliptical orbits for the planets, each one in its own plane, close to the ecliptic. He retained the idea that the Sun is at the centre, and devised the Three Laws of planetary motion. After a full dynamical theory was produced by Newton that explained the elliptical orbits and Kepler's Laws, more and more people accepted that it was right, and that is the situation today, with tiny corrections due to Einstein's General Theory of Relativity.
How did Galileo's success hurt his career?
It was his lack of success that hurt his career. He asserted that the Earth orbits round the Sun following the Copernican theory. The church authorities said that while this could be taught as a useful theory and model for predictions of the planets' positions, it was by no means the whole truth because no adequate evidence for it had been found. The Copernican theory used circles and epicycles, like the earlier Ptolemaic theory, with the difference that the Sun was at the centre instead of the Earth. What caused the rift was the part where the Sun is assumed to be at the centre. Galileo maintained he had proof but that the cardinals were incapable of understanding it. The curch responded by putting Galileo in court for heresy and asking for the proof, but Galileo could not produce proof. In later centuries plenty of proof became available but in Galileo's time there was no proof, so in his own time he was proved wrong and this hurt his career and reputation.
Why do scientists not accept the ptolemaic model?
The Ptolemaic model is also known as the geocentric model, where the Earth is at the center of the solar system. Scientists refute this because orbital paths show that the solar system is heliocentric.
Why was the heliocentric model protested?
Because the Church had always held that the Earth was at the centre of the universe, and it took a long time to gather enough evidence to change this view. Just to say the Sun was at the centre wasn't enough to convince anybody, and it took around 150 more years for the heliocentric theory to gain acceptance after discoveries by Galileo, Kepler and Newton.Galileo's position was that his discovery of the phases of Venus showed a major flaw in the Ptolemaic theory. This was correct but it did not prove the Copernican theory must be right, because Tycho Brahe came up with an alternative system that explained the phases of Venus while still having the Earth at the centre.It contradicted the church, which held to the prevailing, centuries-old dominance of Aristotelian science.
Why did people not trust in Copernicus when he said earth revolves around the sun instead they believed in Ptolemy?
People did not trust Copernicus's heliocentric model primarily because it challenged the long-standing Ptolemaic geocentric view that had been endorsed by the Church and widely accepted for centuries. The Ptolemaic system was deeply ingrained in cultural and religious beliefs, making it difficult for people to accept a radically different perspective. Additionally, Copernicus lacked sufficient observational evidence to convincingly argue for his theory at the time, leading many to remain skeptical of his claims.
How many centuries between 500bce and 1500 bce?
10 centuries, because it is 1000 years.
Why WAS THE PTOLEMAIC THEORY ACCEPTED FOR LONG TIME?
Because the theory had predicted the motions of the planets better than any known method at that time.
