What new idea did Copernicus come up with?
He revolutionized astronomy with his ideas about the heliocentric universe, he also published a book about the orbits of the planets and his ideas about the heliocentric universe
Who propsose a sun-centered solar system?
In 1543, Copernicus published a book about a new idea he had. Most pople in his day thought that the Earth was the centre of the Universe. But, Copernicus disagreed. according to him, the Universe is not centred around the Earth, but the Earthis actually a planet circling the Sun.
How was nicholas Copernicus research proven by Johannes Kepler?
Kepler's theory eventually replaced Copernicus's theory after Tycho Brahe's measurements enabled Kepler to realise that the planets move in elliptical orbits and not in the circles and epicycles of the older Ptolemaic and Copernican models. Copernicus was able to simplify the older model by placing the Sun at the centre instead of the Earth. Kepler in his new theory of 1609 retained Copernicus's idea of placing the Sun at the centre.
Contary to ptolemy what did Copernicus argue concerning the construction of the universe?
Copernicus came up with a new theory of the planets' movements among the stars in 1543. It had the Sun at the centre instead of the Earth, which was in the centre in the ancient Ptolemaic theory. Both theories used circles and epicycles to describe the planet's orbits, which they modelled quite accurately. Copernicus's theory was promoted by Galileo. The modern theory retains Copernicus's idea of placing the Sun at the centre, but it uses elliptical orbits for the planets and was devised by Kepler (1609) working with the latest observations by Tycho Brahe.
What discoveries of Galileo's helped confirm the views of Copernicus?
Galileo's observations through his telescope, such as the phases of Venus and the moons of Jupiter, provided evidence for the heliocentric model proposed by Copernicus. These discoveries supported the idea that Earth was not the center of the universe and that there were other celestial bodies orbiting around the Sun.
