Without a center


Copernicus was not the first person to propose a heliocentric universe; however, Copernicus provided a predictive mathematical model.

Copernicus placed the center of the universe near but not at the sun. Understanding how gravity controls the orbits of planets and moons escaped him, as well as Kepler and Galileo.

Andreas Osiander wrote an preface for the first edition of De revolutionibus orbium coelestium that stated that the Copernican theory was not intended as a description of the literal truth but only as a simpler mathematical description of astronomical observations to improve the calendar.
