Interstellar travel doesn't have to be slow for the travellers. You could get to Alpha Centauri and back to Earth in a day (at least as far as relativity is concerned), but for those who stayed on Earth, a decade would have passed.
That's the twin paradox btw.
- AnimalMuppet 6y agoHow many gs of acceleration would that take? Sure, you could accelerate your mass to a gamma of 6000 or so, and then back down, in half a day, and do it all again for the return trip, but would you still be alive at the end?
- ConceptJunkie 6y agoAt 1g constant acceleration, you could reach the center of the galaxy in your lifetime (~50 years). Everyone else... not so much.
