{wiki=Astronomer_Copernicus,_or_Conversations_with_God}

"Astronomer Copernicus" refers to Nicolaus Copernicus, a Renaissance mathematician and astronomer who formulated a model of the universe that placed the Sun, rather than the Earth, at its center. This heliocentric theory marked a significant shift from the geocentric model, which was widely accepted at the time, and laid the groundwork for modern astronomy. "Conversations with God" is a spiritual book series written by Neale Donald Walsch.
