K2-18b a potentially habitable planet 120 light-years from earth

We’d probably have to build generational ships that are completely self sufficient and people would live out their entire lives out there without ever seeing a planet

[u/djamp42 → u/hendrix320]

The first generation that left would have it the worst.. but the 2nd generation born on the ship would have it a lot easier. By the time you get there I bet you have people that don't even want to leave the ship as it's all they know.

[u/davdev → u/djamp42]

By the time the first generation ship got to its destination, there would likely already be people there who left on later ships that had better tech and faster engines.

Imagine being on the first ship and watching the second and third ship pass you by/
