A: The Earth stays perfect still, at the center of the universe, and the sun revolves around it.
Trust me, I know what I'm talking about.
I've been studying astronomy since the day I could read. I've read everything on the subject; every major text, every discredited theory, every random, half-baked theory that someone jotted down on a piece of parchment.
I've read it all, in order, to better understand the context. I'm up to the year 1512. I highly doubt much has changed since then.
