Granted, this is getting silly, but, the nearest star, Proxima Centauri, is about 4.5 light years away. Zeta Retuculi around 39 light years. I'm ready to hear what fantastic advancements are going to get us there.
well. when the Wright brother flew Kitty Hawk across those sands they would have thought the same thing. They could only just coax Kitty Hawk off the ground but could see that on paper, flight was possible and they proved it. We are all the Wright brothers - we know it is possible to fly to the moon with ridiculously basic technology.
We also know what the speed of light is and the philosophical/Mathematical boundaries this creates for us - but we are spending billions to find the answers to these questions (CERN and Tevatron) and getting promising results. The future of space travel is exotic THAT'S for sure. Ranging in exoticness from the very basic obvious rationality of the Space Elevator (a fiery plume has been so yesterday since at least ten years ago) to the extremely exotic knowledge that lightspeed may not even be a factor in the calculation of the space-time transit, especially in the case of the warping of the space-time continuum allowed by the theory of Mr Einstein.
