Known Space; why so small??
I am quite new to the Known Space universe of Larry Niven. Ive just read Ringworld and Ringworld Engineers.
Why is known space so small? Its like 60 ly across, isnt it???
Even with hiperdrives that take weeks to travel a ly, its hard to believe humans are not exploring further away.
Maybe other books hint about the reason for the small human exploration and size of known space. Can anyone enlighten me?
