Ptolemy knew that the Earth was spherical, and he knew it was roughly 24,000 miles around. He reasoned that if the Earth were rotating daily, it would produce a wind of about 1000 miles per hour, which would knock everything over. There was clearly no such wind, and so the Earth was clearly not rotating daily.
What else can I help you with?
When was ptolemy's discovery?
everything revolved around the earth.
According to Ptolemy what was the earths position in the?
The very center. he belived everything revolved around the earth.
What was the error in ptolemy theory about the structure of the universe?
Ptolemy's theory was incorrect because he believed the Earth was at the center of the universe and that the other planets and the Sun revolved around it. However, he was later corrected by, I believe, Copernicus (Ca-per-ni-kus) who stated the Sun was in the center of the universe and that the planets, including Earth, revolved around it.
Which assuptions do ptolemy and Copernicus disagree upon?
Ptolemy thought the earth was the center of the universe, so that the stars, the other planets and the sun revolved around the earth; Copernicus realized that for the orbits of the planets to make sense, the earth and the other planets had to revolve around the sun.
According to Ptolemy where was the sun relation to earth and the other plants?
According to Ptolemy's geocentric model, the Earth was at the center of the universe, and all celestial bodies, including the sun and the planets, revolved around it in circular orbits. The sun was positioned on a deferent circle that revolved around the Earth, following the movements of the planets. This model placed Earth as the focal point of the cosmos, with the sun serving as one of the key bodies orbiting around it.
According to ptolemy what was earths position in the universe?
Ptolemy believed that Earth was the center of the universe, with the Sun, Moon, and other planets revolving around it in circular orbits. This geocentric model of the universe was the prevailing view in Western civilization for over a thousand years.
What did Ptolemy believe the earth went round?
Ptolemy believed that the Earth was a stationary sphere at the center of the universe and that the Sun, Moon, planets, and stars revolved around it in perfect circular orbits. This geocentric model of the universe was accepted for centuries until the heliocentric model proposed by Copernicus.
How did Copernicus' view differ from ptolemy's?
Copernicus' view was that the sun was the centre of the solar system. He believed everything revolved around the sun in circular orbits. Ptolmey on the other hand placed a static Earth at the centre with the planets and the sun orbiting the earth.Copernicus thought that the solar system revolved around the sun and not the Earth.
Who was wrong about the theory of the universe?
Ptolemy thought that the Galaxy revolved around the Earth, this being called the Geocentric model. This is not possible as the Sun had a greater mass and gravity than the Earth. The Earth would be being pulled in by the Sun, not the other way around.
How many times did earth orbit the sun between 140 C.E when Ptolemy introduced his theories and 1543 when Copernicus introduced his?
The earth revolved around the sun 1403 times between 140-1543.
What did ptlomey believe?
Ptolemy believed in a geocentric model of the universe, in which Earth was at the center and the planets and sun revolved around it in circular orbits. He also developed mathematical theories to explain the motion of celestial bodies.
What was the major error in Ptolemy's theory about the structure of the universe?
Ptolemy's theory was incorrect because he believed the Earth was at the center of the universe and that the other planets and the Sun revolved around it. However, he was later corrected by, I believe, Copernicus (Ca-per-ni-kus) who stated the Sun was in the center of the universe and that the planets, including Earth, revolved around it.
