@Vexx: Wow, thanks for introducing me that book! Now I know that I'm not the first or the only one to have thought of this. And the story is rather fitting too, socially speaking.
Btw, to refute your argument a little. True, it isn't
necessarily infinite. But Earth also wasn't necessarily flat or the center of the universe. Let me just say that to me: imaginations, possibilities, and uncertainties are what make life interesting. And science is less whole without them.
That's enough for this topic, let's move on.
