Consider that the galaxy is 100,000 light years across so even if there are a couple of other habitable planets out there, we aren't likely to get there for millennia.
- sethrin 10y agoWithout invoking abuses of either relativity or the rocket equation, current physical understanding more-or-less limits us to long-term 'generation ships'. There is some potential argument about cryogenic freezing/revival, but it may be more accurate to talk about human-descended life forms walking on exoplanets rather than homo sapiens sapiens per se.
