How does democracy function in a society where air is rationed—and possibly under corporate control? How does sociology change if humans can’t reproduce unless they’re in Earth-normal gravity? How do we avoid a scramble for territory if some regions of space are better than others? Incidentally, what is the actual space law today, how did it get that way, and is it likely to change? These questions seemed very basic to space settlement, and frankly really interesting, but were typically skipped over as things that would just get worked out as the rockets got bigger.
All of these questions come up in one form or another in The Expanse, which is cool. Maybe it will be a primer of sorts…
