The whole FTL issue will be a hindrance to spreading outside the solar system.
I did read an odd article a while back about how Einstein got it wrong and it is possible to exceed light speed if you keep accelerating.
Not a problem at all once biology is fully understood. It only takes 22 million years for Sol to orbit the galaxy. We simply build space stations that are self sustained ecosystems. It does not matter how many generations exist before arrival at a destination. The issue is our hubris in the present and desire to be something more than we really are in the grand scheme of the universe.
