Comment It's not the universe, it's the concept... (Score 5, Insightful) 1190
I think what makes great science fiction isn't the universe, it's the concept behind it. Of course, you can argue that this is what distinguishes short stories (which tend to be much more concept-oriented) from novels (which need to develop deeper characters, unless you can figure out a device like Asimov used in Foundation to get away with shallow character development). Still, I can think back on the great science fiction I've read, and most of it is really about the ideas, not about the universe.
After all, most sci-fi universes are just our own universe with something changed - a more complicated version of a Sliders episode. If everything were actually different, we'd have no reference point and it wouldn't mean anything. It's the fact that almost everything is the same except for some crucial difference (more advanced technology, or the Nazis winning WW2, etc.) that makes the stories compelling. That's why so many of these stories include some kind of foil character that the reader can identify with (Arthur Dent is a good example of this, but literally almost every single sci-fi book ever written contains at least one main character that is strikingly similar to people contemporary to the author's own culture). The story can often be created simply by allowing the contemporary typical person to clash with the changes introduced in the universe.
