Galelei derived his theory from Copernicus. To Copernicus it was just a theory. Galilei managed to prove it when he invented the telescope and was able to see the moons orbiting Jupiter.
Copernicus created the mathematical theory to prove that the Sun, not the Earth, was the centre of our solar system. Galilei provided the calculations and observations to prove Copernicus' theory.
Galileo Galilei provided evidence in support of Copernicus' heliocentric theory through his observations of the moons of Jupiter and the phases of Venus. His work helped to validate the heliocentric model and contributed to the eventual acceptance of the theory.
Copernicus was in 1543, a polish astronomer named Nicolaus Copernicus. Copernicus's theory - The sun is at the center of the Universe. Galileo Galilei was in 1609, Galileo became the first person to use a telescope to observe celestial bodies.
The heliocentric theory, which posits that the Earth and other planets revolve around the Sun, originated in the 16th century. It was proposed by astronomers such as Nicolaus Copernicus and further developed by Galileo Galilei and Johannes Kepler during the Scientific Revolution.
Copernicus' theory was that Earth is not the center of the universe and we revolve around the Sun.
Copernicus' theory was that Earth is not the center of the universe and we revolve around the Sun.
Nicolaus Copernicus was the Polish scholar who published a heliocentric theory in his treatise 'On the Revolution of the Heavenly Spheres' in 1543. This theory proposed that the Sun, rather than the Earth, was the center of the universe, leading to significant changes in our understanding of the cosmos.
A hypothesis is an educated guess on the possibility of some phenomena while a scientific theory is when the phenomena is confirmed by observation.
The sun-centered theory, known as heliocentrism, was confirmed by observations made by the Polish astronomer Nicolaus Copernicus in the 16th century and further supported by the observations of Galileo Galilei in the 17th century. The idea that the Earth revolves around the sun replaced the previously widely accepted geocentric model.
Galileo Galilei . He only helped support the theory through his observations , he didn't invent the model, Copernicus did.
Nicolaus Copernicus and Galileo Galilei were two scientists who believed that the Earth revolved around the Sun, a theory known as heliocentrism. Their work challenged the prevailing geocentric model of the universe and laid the foundation for modern astronomy.
