LaoNicolaus Copernicus proposed a heliocentric model of the universe where the Earth and other planets revolve around the Sun, challenging the prevailing geocentric view of the medieval period that placed Earth at the center. This shift in perspective laid the foundation for modern astronomy and our understanding of the solar system.

How current models of the solar system differ from either Aristotle or Copernicus model?
Aristotle had thought that the Earth was the Geo-centric or the center of the universe and everything circled or revolved around it. Copernicus thought that the Sun is the center of the universe. Copernicus' idea is called Helios-centric.
How did Copernicuss view of earth's position in the universe differ from Ptolemy's?
Copernicus proposed a heliocentric model, where the Earth and other planets revolve around the Sun, while Ptolemy's model was geocentric, with Earth at the center of the universe. Copernicus' model challenged the prevailing belief that Earth was the center of the universe and laid the foundation for modern astronomy.
How might the objects found in the early universe differ from the objects found in the universe now?
In the early universe there was only Hydrogen and Helium (and a smidgen of Lithium).
What is sub universe?
A sub universe refers to a smaller, self-contained universe that exists within a larger universe. It could represent a specific domain, dimension, or system that operates independently within the broader scope of the main universe. Sub universes can have their own rules, laws, and characteristics that may differ from the overarching universe.
How does the heliocentric model differ from the geocentic model?
The heliocentric model places the Sun at the center of the solar system, with the planets, including Earth, orbiting around it. In contrast, the geocentric model has Earth at the center of the universe, with the Sun and other celestial bodies believed to orbit around it. The heliocentric model was proposed by Copernicus in the 16th century, challenging the previously widely accepted geocentric model.
