He did think that when he devised his theory, in the time of the Roman Empire, and people believed it for another 1400 years. There were other theories in the 16th century including one by Copernicus who placed the Sun at the centre instead, and then Johannes Kepler produced a new heliocentric theory that was confirmed by later theoretical discoveries of Isaac newton and others.
Now everyone believes the Sun is at the centre of the local Solar System, with the planets in elliptical orbits following Kepler's model.
Apart from some tiny modifications from Einstein's General Theory of Relativity, Kepler's theory is in use today all over the world. But Ptolemy's theory was still used for planetariums until computers came along.
Yes, by his time, the geocentric model was no longer widely accepted and nearly every scientist agreed that the Earth revolved around the sun.
Ptolemy believed that Venus, like other planets in his geocentric model of the universe, exhibited phases due to its position relative to the Earth and the Sun. He thought that the varying shapes of Venus as seen from Earth were caused by the changing angles between the three celestial bodies.
He believed that everything rotated around the sun. Also, he believed that the planets orbit were not circular, they are oval. He was a catholic, but they didn't like him because he was going against the church with what he believed.
Galileo believed that space was a vacuum without air and that celestial bodies like planets and moons moved in a mathematical, orderly manner. He also supported the heliocentric model proposed by Copernicus, which stated that the Earth and other planets revolved around the Sun.
Nicolaus Copernicus proposed that the Sun, not the Earth, was the center of the solar system and that the planets, including Earth, revolved around the Sun in circular orbits. This heliocentric model challenged the prevailing geocentric view of the time.
i think he was tring to figure out how the universe was shaped. he probably thought the earth was in the middle of everything because we could see the sun and the moon from earth, but the other planets only at certin points each year
Galileo, I think.
Eudoxus thought that the planets revolved around the Earth not the Sun.
that the earth was in the middle of the universe
He knew that the planets revolved around the sun in an elliptical orbit.
Galileo thought planets revolved around the sun because when he observed Jupiter, he noticed that its moons revolved around Jupiter and not earth. So everything else led up to that the Earth revolved around the sun.
Most ancient civilizations believed that everything revolved around the earth and in most cases they believed the earth to be flat. Also, it may have based around the religion of the civilization.
I think it would depend on who you asked. A serf might say life revolved about his lord. The lord might say life revolved around the king. The king might have said live revolved around the pope. And a pope might have said life properly revolved around the congregation, which was mostly made up of serfs.
Yes, by his time, the geocentric model was no longer widely accepted and nearly every scientist agreed that the Earth revolved around the sun.
Well for many years they believed the earth was the centre of the universe and thus everything revolved around the earth as opposed to the earth revolving around the sun. Think of a model where the sun revolved the earth, you can't even comprehend where the sun would go! heliocentrism is the current theory of the solar system, yes it's still a theory because that's how science works. Sciennce doesn't say it's a fact it just has many facts supporting it making it a strong theory.
they thought the universe revolved around the world and thought other theories impossible
Ask not what Ptolemy thinks of his solar system, but what his solar system thinks of Ptolemy.
