  • With that kind of propulsion politically available, I doubt finding workable combinations of mitigation strategies to interstellar medium hazards would be the showstopper. Especially not one to hold us back for time scales that oceans did. Getting humans interested in prioritizing projects like that, to me, is the real headscratcher.

Though perhaps even more incredibly he actually does come all the way back. The historicity of his accounts is disputed and maybe only a part of it is true, but even if he only got as far as India, I still find it fascinating to imagine doing at that time.
