The Universe within 12.5 Light Years - The Nearest stars
Pretty awesome when you think about it. Assuming we don't kill ourselves and are able to either develop some kind of faster, cost-efficient space travel (as obviously light speed is out of the question, and even near light speed is out of the question for at least a long time), it would only take us 20-30 years to get to some of these star systems.
I can totally see a "stellar neighborhood" in our little corner of the cosmos happening here.
