Prior to accepting this knowledge, man thought the Earth was flat and that the Sun was rising and setting about the Earth. Now we know that it is indeed the Earth that revolves around the Sun.
I used to think I was the center of my own universe, then I discovered I am one of many.
Yet I still haven't discovered what indeed I revolve around. But this much is true, I revolve around the Sun, and its gravity that keeps me in rotation.
