The motion of planets is not uniform and circular.
The universe includes objects we cannot see.
The sun is at the center of the universe.
The new idea introduced by Copernicus that significantly modified the geocentric model of the universe is that the sun is at the center of the universe.
The correct answer is "The sun is at the center of the universe."
To arrive at this answer, one would need to study the history of astronomy and the contributions made by various scientists. One of the pivotal figures in this field is Nicolaus Copernicus, a Polish astronomer who lived in the 16th century. Copernicus challenged the prevailing geocentric model of the universe, which placed the Earth at the center and all celestial bodies revolving around it.
Copernicus proposed a heliocentric model, which means that he suggested that the sun, rather than the Earth, is at the center of the universe. This idea was a significant modification to the existing understanding of the universe and had far-reaching implications for our understanding of planetary motion.
To learn more about this topic, one could study Copernicus' book, "De Revolutionibus Orbium Coelestium" (On the Revolutions of the Celestial Spheres), which laid out his heliocentric model and the evidence supporting it. Additionally, studying the work of other astronomers who further developed and confirmed the heliocentric model, such as Johannes Kepler and Galileo Galilei, would provide a deeper understanding of this new idea.
