Earth currently resides on a bridge of stars and planets, Orion's Spur, that connects to all the arms of the galaxy, the Milky Way (Galactus). How likely is it that mankind will inherit the rest of the galaxy by free trade, war, peaceful action, colonization, etcetera? What threatens us from ever meeting such ends? We are presently 30 seconds from Mars. Feel free to weigh in on the destiny of the galaxy and mankind.
