Humans aren't equipped for diving to the bottom of the ocean, flying in the stratosphere or walking on the Moon either. Alas, the time when we were limited to a specific environment and couldn't break out of it is long past. You're comparing that to intergalactic travel? Rofl. Interstellar, not intergalactic. The fact that you treat them as if they were interchangeable says a lot. Interstellar travel should be technically feasible for a civilization with a developed presence in its own system (low-cost launches due to economies of scale, industrial activities such as asteroid mining, settlements on more than one planet, solar power satellites, etc.. As in, there are technical designs for interstellar propulsion that we know to be realistic for a civilization with that kind of energy and resource availability. I don't think the fact that we haven't gone beyond the Moon in fifty years is significant, because technological development (and economic growth) of this kind won't happen within decades. |
