The sun rises in east and sets in the west. It obviously moves through the sky. Common sense tells me that when I sit, I am at rest. But that which is evident is often wrong. All facts have a shelf-life and science is the process of endlessly rediscovering the truth. The photo above shows the first depiction of the sun as the center of our universe; a sun that does not move and an earth that moves us perpetually.
