Images of the 1986 Challenger disaster stirred all these thoughts about the future of space travel and that critical achievement, sustainable colonization. Old fashioned rockets vs quantum tp, or perhaps sophisticated organic 3D printing ~ will we print ourselves to remote locations any time soon? If so, finding a viable destination would appear to be the sensible priority, which I suppose is what justifies projects such as Kepler. What a steep challenge lies ahead ~ even if we were to harness adequately Alcubierre’s ideas, if only to send robots and printers to pave the way. How far should we go? How far will we ever go?
