the heliocentric theory is the theory that the sun is in the center of the universe. the geocentric theory is the theory that the earth is in the center of the universeGeocentric models had the earth as the center of the universe with the sun and all the planets orbiting it. Heliocentric models (the current accepted ones) have the sun as the center, with the earth and planets orbiting it.Geocentric was the idea developed by the Greek philosopher Aristotle of an earth-centered view of the solar system. With Christianity's influence, people had thought that God put Earth in the center of the universe. Heliocentric came later on by Italian astronomer Galileo that the sun was put at the center of the solar system while Earth and all the other planets orbit around it.
The word for earth-centered is geocentric,
The heliocentric theory was originated by Copernicus.
He was a Polish mathematician who disagreed with Ptolemy's view that the earth is the center of the universe. The heliocentric theory is the theory that the sun is the center of the universe, not the earth.
It sounds like your teacher was referring to the geocentric theory, which states that the Earth is at the center of the universe, with all other celestial bodies revolving around it. This theory was widely accepted in ancient times until the heliocentric model proposed by Copernicus.
Aristotle's earth-centered theory of the universe is called geocentrism. It posited that the Earth was stationary at the center of the universe, with celestial bodies orbiting around it in perfect, circular paths.
that the world was heliocentric not geocentric aka sun centered universe and earth centered universe
observation proved the theory true.
Ptolemy. (his full name was Claudius Ptolemaeus).
1,500 years :D
A geocentric theory is one that states the universe is centered by Earth. Geo means earth. The old Ptolemaic Model of the universe has earth as the center. A heliocentric theory is one that is centered by a source of heat. Helio = heat. It basically states that the sun is the center of our galaxy. (Copernican Model)
1,500 Years .
No! It is heliocentric, or sun centered.
Nicolaus Copernicus proposed the earth centred theory
No Nicolaus Copernicus did not believe in the earth centered theory he believed that the earth and other planets center and revolve around the sun.
Galileo's most significant observation and discovery was that the universe (or now the solar system) was Sun-Centered. Originally, people accepted the Copernican theory that the universe was Earth-centered. For a few years Galileo had to defend his discover until 1616.
