Relativity

Once the area of science fiction, we now see more and more proof of the existence of extrasolar planets. Today's Astronomy Picture of the Day shows a graph built from the data from NASA's Kepler observatory. Models predict ten billion "Earths". Ten. Billion. Now, there are some caveats to the prediction (such as where these planets orbit), but I'll bet this turns out to be a lowball figure.
