Which Greek scientist suggested that the earth was at the center of the universe?

The model which Aristotle proposed in the book on the heavens was that Earth was in the center of the system and thus the universe with the known planets and Sun moving around us in perfect circles. This was latter propagated by Ptolemy who latter proposed the idea of the fixed stars.
First problem was that neither of the scientists could explain why the system was arranged so.
Secondly what lay after the fixed stars was never made clear. This was used by the church to put the Heaven and Hell after the fixed stars.
Thirdly Galileo had found out that Jupiter had many satellites orbiting it. Now with the basic assumptions any body can understand that this complex orbit would end in many collisions and also if Earth was so special why would Jupiter have many orbitals too.
These were the basic problems.

∙ 13y agoMany people thinks that Nickolaus Copernicus were the first man to put up a theory with the Sun ''in the middle''. That is not true, it were Aristarchus. Later in history, people doubted that again. And then Nickolaus Copernicus came with the same theory. So actually, first, we were right, then wrong, and then right again!

The heavenly bodies were believed to be attached to the
revolving crystalline spheres
in the following order: moon, Mercury, Venus, Sun, Mars, Jupiter, Saturn, fixed stars, and finally the sphere of the Prime Mover. The motion of the Prime Mover created the angular velocity which was imparted to each inner sphere and caused the motion of the entire universe model.

He actually lived in AD 90 - AD 168 and was a Roman citizen of Egypt who wrote in Greek and was not really Greek.

There are eight circles carrying the seven planets and the fixed stars.
Starting from Earth they are:-
- Moon
- Sun
- Venus
- Mercury
- Mars
- Jupiter
- Saturn
- Fixed stars

And as for Greeks who thought that the Earth was the center of the universe, you may be referring to Aristotle, who was a philosopher. And like philosophers today, managed to convince himself of a lot of hogwash that wasn't true. The LAST thing that Aristotle was was a "scientist", and he would have been insulted by the term if he'd ever heard it.
Aristotle, by the way, may have been the wrong-est person who ever lived, and probably set back the progress of science and medicine by 1500 years. His physics were kindergarten-quality, his anatomy laughably wrong; Aristotle's medical textbooks are probably responsible for more deaths than any other human being in history.

∙ 13y agoAristotle thought that the Earth was at the center of the solar system, which is the geocentric model. He believed we were staying still entirely, and that other planets and the sun were orbiting around us. In the way that we have eclipses for our planetary motion, he had spheres to account for the radical motion of the planets, which would become apparent under the idea that the earth did not move.
The order of the solar system according to Aristotle was (from earth out) Earth, the Moon, Mercury, Venus, the sun, Mars, Jupiter and Saturn. (Pluto and Neptune had yet to be discovered.) Outside this were the stars, and outside this was the "Prime Mover" that moved the stars at a constant speed. It also moved all of the other things in their orbits.
On an interesting note, the Christian Church adopted this idea in Medieval times, and they changed the prime mover to God, and the sphere of the firmament to be heaven. Only later was the heliocentric or sun-centered model introduced, and Copernicus, who introduced it, was taken to task by the Church for what was considered blasphemy.

∙ 12y agoAfter years of work with the notebooks of data from Tycho's lifelong observations,
Kepler came around to the decription of the solar system that fit Tycho's data best:
that the planets revolve around the sun in elliptical orbits with the sun at one focus
of each, that each planet moves faster when it's closer to the sun and slower when
it's farther from the sun, and that the ratio of
(square of the panet's orbital period)/(cube of the planet's distance from the sun)
is the same number for each planet.
Kepler came to that view by spending years analyzing Tycho's observations.
Almost 100 years after Kepler's death, Newton came along, wrote down a
theoretical formula for the force of gravity, and showed that if his theory of
gravity is correct, then planets must behave exactly as Kepler thought, because
that's how gravity works.

What were the early ideas of the solar system and who thought of them?
Aristarchus of Samos thought that the sun was at the center of the universe and some "educated" greek people thought that the earth was the center of the universe but they were dead wrong because modern science now has evidence that the sun is the center of the universe.
Who was the first propose that the sun was the center of the universe and everything else revolved around it?
No--he believed that the sun was the center of the universe.
Who was Anaximander?
AnaximanderThe Greek natural philosopher and astronomer Anaximander (ca. 610-ca. 546 B.C.) attempted to explain the origins of the universe through his theory of the apeiron.Anaximander was a pre-Socratic Greek philosopher from Miletus. He belonged to the Milesian School and learned from his master Thales.
Who was Lakshmi reincarnated from?
Lakshmi, an Indian goddess, can be thought of as an incarnation of Devi, the mother of the Universe, or Radha, the eternal consort of Krishna. She corresponds to the classical Greek goddess Aphrodite.
Where did geometry originate from and how?
Geometry has always been with us since the birth of the Universe and it was mankind who worked out its geometrical features over the past thousands of years. Geometry stems from a Greek word meaning land or Earth measurement.
Who was the greek scientist who believed the earth was the center of the universe?
Aristotle and Ptolemy - pick one.
What Greek scientist first put forth a heliocentric view of the universe?
Copernicus.
What were the early ideas of the solar system and who thought of them?
Aristarchus of Samos thought that the sun was at the center of the universe and some "educated" greek people thought that the earth was the center of the universe but they were dead wrong because modern science now has evidence that the sun is the center of the universe.
How did Copernicus and Kepler change peoples view of the world?
They were the first 'modern' (well, medieval) scientists to come up with the "heliocentric" view of the universe: the concept that the Earth revolves around the Sun and is not the center of the Universe itself. It should be mentioned that ancient Greek scientist had already discovered that some 1,500 years earlier, but their writings had been more or less forgotten by then. Well, not quite: it was much later discovered that Copernicus referred specifically to those earlier Greek findings in the draft of his book, but left it out in the final text.
Who described a geocentric universe in a book?
Claudius Ptolemy was the ancient Greek astronomer who described a geocentric universe in his book "Almagest." He believed that the Earth was at the center of the universe, with the planets and stars orbiting around it.
How was ptolemy's different from the earlier Greek model?
Ptolemy's model is different from the earlier Greek model because Ptolemy developed a compllex geocentric model of the universe and his model seemed to explain motions until the 1500s.The early Greek astronomers believed that Earth was the center of the universe.
Who was the first propose that the sun was the center of the universe and everything else revolved around it?
No--he believed that the sun was the center of the universe.
The Greek scientist Aristarchus was the first person to suggest what?
He first suggested that the Earth (and the other planets that were then known) rotated around the Sun instead of the other way around.
How was Ptolemy model different from the earlier greek model?
Ptolemy's model is different from the earlier Greek model because Ptolemy developed a compllex geocentric model of the universe and his model seemed to explain motions until the 1500s.The early Greek astronomers believed that Earth was the center of the universe.

Which country suggested that the sun was the center of the solar system?
Galileo was an Italian. Nicholas Copernicus was Polish. Aristarchus of Samos was Greek. These men suggested the sun was the center of the solar system. No country ever really adopted that position, but Galileo's stance eventually became popular among Italians and then the rest of the world.
Did the Greek invent the catapult?
no the greek did not invent it . a greek scientist invented it.
