To Whom are you speaking, here? What is the fastest moving man-made object (pioneer 1, or voyager 1/2)? These are not even under acceleration. It should be very feasible to design Probes that can reach .1c and beyond. It also conceivable that habitat ships could also reach high speeds (although Acceleration would be very slow, and you wouldn't want to be going so fast that dust particles would do tremendous damage to the ship (a flaw in FTL travel)). But the point is that at .1c the galaxy would be colonized in a short time by an intelligent species. Even at .05c or .025c or .0125c, etcetera, the galaxy would /still/ have been completely colonized by now. Doesn't the drake equation show that there could be anywhere from thousands to millions of intelligent civilizations out there (in our galaxy alone, let alone the cluster or the universe)? So where are they? _They should have been here by now_.
