“Aristotle believed that objects fell to the ground because they were drawn to the center of the earth. It was only millennia later that gravity was discovered, and Aristotle’s beliefs were dismissed.”
ummmm….objects do fall to the ground because they are drawn to the center of the earth. (The reason they do so doesn’t have to do with something specifically located at the center of the earth, but they are attracted to the earth, and it is the center of the earth that they are pulled to because that is the center of mass.)
