I'm looking for the title and author of a sci-fi book I read while in Jr High school (1985 - 1987)
Basic plot from what I can remember:
The novel is set on a spaceship or space station that has been floating through space for 100's - 1000's of years. There is a group of people living on this ship in a section that is totally self contained. The people have been living here for 100's of years and don't believe that anything else exists outside of their contained section. One guy decides to challenge the notion that nothing exists outside of where they are and breaks through.
I could have sworn that this was an Asimov book, but I've gone through his catalog and can't find anything plotwise remotely close to this. Any help at all is greatly appreciated.
