Instead of spending paragraphs or entire chapters explaining the rules of this fictional world — the breeding habits of the native Grew, the intricacies of the spacecorn trade, the atmospheric pressure of Planet X — have that information roll out gradually through character action and dialogue. It’s simply a genre specialized version of fiction’s holy paean of SHOW DON’T TELL.
I’m telling you all this to make sure we’re on the same page when I say that Seveneves feels something like sixty percent infodumps. Or more. The moon explodes and all life on earth is doomed. What follows is lengthy descriptions of how, in the brief span of time we have left, humanity builds a set of vessels in space to survive our five thousand year exile from earth, waiting it out until the surface of the earth stops being bombarded by lunar debris and cools down. So the meat of Seveneves is technical explanations of the the structures humans are building in space, and how it is possible to build them. This is coupled with a primer on the science — with a particular emphasis on orbital mechanics — required to understand how space works.
Don’t get me wrong: There are characters, and they’re not poorly developed, though many are stand-ins for real life people. A Neil Degrasse Tyson stand-in named Doob is central. Hilary Clinton and Jeff Bezos analogues make appearances. But we’re talking about a 900 page book here. Characters and plot are not the focus, which is sort of counter to popular theory of what a novel ought to be.
Anyway, I thought it was great. I’ve never been partial to golden rules. Or rules of any kind really.
By attempting to encase the novel in real science, either what we can already do now or what we think we can do in the very near future, there’s an authenticity to the theory that makes it sing. I’m not a scientist. I have zero idea how much of this came from Neal Stephenson’s imagination and how much of it is solidly based in fact. But he sells it well enough that the novel feels like a legitimate merge of non-fiction science text and fictional adventure.
It does take a leap in the last few hundred pages, literally, time jumping to five thousand years in the future wherein humanity is terraforming earth in hope of returning full time. While the science theory is still there, sort of, it morphs into a second-rate fantasy novel that feels vaguely like Stephenson trying to create a setting for a video game RPG. It’s not bad exactly. Still a fun beach read. But a dramatic step down from the first two sections of the novel.
