Copernicus was an astronaut and Mathematician, it is during the research that he was able to get the principle idea that the earth was not at the center of the universe.
Copernicus suggested a heliocentric model of the universe. Meaning, the earth was the centre of the universe and other planets had to orbit around the earth. This model of the universe was against Ptolemy's model of a geocentric model; a stationary Earth at the centre of the universe.
He believed in Heliocentrism (That the sun was the centre of the universe, not Earth).
he went to jail because he said the earth was not the centre of the universe. However in the bible it says that the earth IS the centre of the universe. He was thrown in jail for saying the bible was wrong.
The first scientist to say the earth is not the centre of the whole universe was Nicolaus Copernicus early in the sixteenth century.
Brahe's theories revolved around the ptolemaic system, where Earth was the centre of the Universe. Copernicus stated that the Earth is not the center of the Universe, but we revolve around other masses as well.
Solar centric or more usually heliocentric put the sun at the centre of the universe as opposed to the earth at the centre. We now know this to be inncorrect though the sun is at the centre of the 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.
Everyone thought that the sun orbits the Earth and all other planets but Copernicus studied the ski carefully. He found out that the Earth and all other Planets orbits the sun and the earth is not the centre of the universe. The sun is.
They believed in a heliocentric universe. This meaning that the earth was not the center of the universe, but that the sun was. However, many people , including the church, did not agree with this theory. Instead they believed in a geocentric universe. Plato and Aristotle believed in this theory.
Copernicus put forward the idea that the Sun, rather than the Earth, was at the center of the universe.
