I am verifying the answers generated by an automatic system to the following question: who was the first to argue that the sun was the center of the universe
Suggested answer: With the observations of William Herschel , Friedrich Bessel , and others, astronomers realized that the sun was not the center of the universe and by the 1920s Edwin Hubble had shown that it was part of a galaxy (the Milky Way ) that was only one of many billions.
Should I validate this answer?
