"At rest, however, in the middle of everything is the sun"

The quote "At rest, nevertheless, in the middle of everything is the sun" by Nicolaus Copernicus describes his theory of heliocentrism, which challenges the extensively accepted view that Earth is the center of deep space. Copernicus recommended that the sun, rather than the Earth, is the center around which all planets revolve. The expression "at rest" stresses the significance of the stability and immobility of the sun, which played a crucial role in Copernicus' argument for heliocentrism. This theory had far-reaching implications for our understanding of the structure and function of deep space and was a considerable turning point in the history of astronomy.
