That's the question at hand in this thread. I list about 20 reasons for coming here in Flying Saucers And Science. I think the most important is that we suddenly pose a threat to the neigh- borhood because we will very soon be able to bother others and because we are nasty having exploded 2000 nuclear warheads. By the way it would take quite a bit of very heavy elements to increase our density even a few percent. And Fusion is appropriate for interstellar travel...
