Here we go again... :( The earth is at the center of the universe. Spontaneous generation creates rats. Anyone who disagrees with these things is a liberal atheist. Why science itself is liberal! Let's just abandon all science, live in huts, and ignore any challenge to our orthodoxy.
Good heavens, it's 2006, and we're still debating if evolution is real. Sad but true. And for the record, I am a staunch Christian.
As a practical matter you can imagine that you are at the center and move out from there. The mathematics involved supports that and numerous other conjectures.
I'm still waiting to see if they've finally disproven that it's actually shaped like a dodecahedron.
