I might be wrong, but I think that\'s how Firefly (The Series) handled their universe. Instead of humanity being spread around an entire galaxy, it was spread within two or three large star systems, all relatively close together (In fact, I think the star systems were all orbiting one giant central star!) One giant star-system would be a nice way of avoiding the more Sci-Fi heavy (magic-like) forms of travel. Although, that being said, I\'m not sure how possible/likely a system like the one described above is.
