The solar systems seem far away now, but they wont seem far when we are able to travel through space at 99% of light speed. Eventually humans will need to spread through the cosmos, and we will find a way. even if it means drifting for aeons on hulking ships which support immense populations, it is unavoidable: Humans will spread through the universe.
