Copernicus argued that the earth revolved around the Sun. What’s odd about this statement is that the Sun is presumed to be static. However, the Sun itself resides within the universe and occupies a location, which, oddly enough, is presumed to be an absolute location. However, does the Sun move? And if it does, how? Isn’t the Sun outside the center of the Milky Way Galaxy? Does it revolve around the core of this galaxy? Does the Milky Way itself revolve around a central galaxy?
