There's a thought. After taking 4 generations to get there (and just imagine the nature of the politics on-board that ship, across 100+ years), our traveling descendants find it hard to even move around on Nova Terra's gravity.

Then, turning the ship around to travel back to Sena Terra with our new-found friends, 200 years have passed, and out of that ship emerges Superman, able to leap tall buildings in a single bound...

The mind boggles.
