Update: Still bummed about the 11-million-year commute to the planet Kepler B we discussed last month? Be sure to read BoingBoing’s article on the (im)practicality and cost of interstellar travel. While Kepler 22b might be a boring 11-million-year flight away, the nearest star, Alpha Centauri would only be a brisk 70,000 years or so.
