I’ve been deeply affected by Neal Stephenson’s latest novel Seveneves. While I am often a slow and somewhat lazy reader, I found myself taking every opportunity I could to dive back into it. While my favorite novel, Anathem, also by Stephenson, presented a world I wanted to explore more deeply and spend more time in, I found that the story of Seveneves was one that I wanted to tell everyone I spoke to. I didn’t of course because everyone would hate that.

But this is the kind of book we’re talking about, where each event, each decision, and each change of fortune filled with suspense and excitement for what came next, and an enthusiasm to share with others what novel and evocative things I was experiencing.

I’m left with so many thoughts and questions. I don’t necessarily consider the fact that these questions haven’t been sufficiently answered to be a problem or a mistake by Stephenson, but immediately after finishing the novel, they are swirling in my mind, demanding my attention.

Here are some of those thoughts and questions, in no particular order, a few of which are simple questions about “what happened” to certain characters or with certain events that simply aren’t told, and others are more nuanced regarding motivations, character, and connections.

An obvious warning: If you haven’t read the book, I’m going to spoil pretty much everything here. It’s like a nuclear-spoiler bomb. If you have no intention of reading the book, or don’t care about spoilers, there’s probably no reason for you to read this post anyway.

Quickly: In Seveneves, the moon blows up because of unknown “Agent,” which humanity learns will kill everyone on Earth within a couple of years due to pieces of the Moon raining down like fire, wiping out everything. So the people of Earth send a select few into orbit with the International Space Station to begin the “Cloud Ark” to live in space until such time, thousands of years later, that they might return to Earth. Lots of awful things happen which lead to there being eight people left, all women, seven of them able to have kids. Through genetic manipulation they propagate the species on an asteroid where they parked the space station. 5000 years later, we see what humanity has become, an orbital species of seven races, only now beginning to dip its toe into repairing and repopulating Earth. Got it?

The book handled well the curious and difficult balance between the enormous impact of the end of life on Earth and the relatively smaller crises and concerns of the Cloud Ark population. This is a book about those people, not those lost in the Hard Rain, but I would have loved (in another volume or book?) a deeper exploration of how humanity coped with knowledge of its inevitable demise in one fell swoop. My brain would often hang on questions about how governments, economies, and institutions could continue plodding of their own inertia over the two years of preparation. The book cites isolated incidents of violence and riots on Earth (not including the zero-hour standoff in Venezuela), but my mind reels at the idea of a planet full of people all processing their absolutely-assured deaths. Maybe no book could handle it.

One real triumph for Stephenson in this book is how he brings to bear his penchant for detailed description. In The Baroque Cycle, I was often entirely lost and confused by his meticulous and lengthy descriptions of each setting’s most micro and macroscopic details, or long events with several characters all doing a lot of things I couldn’t keep track of. Anathem occasionally left me a big agog in a similar fashion in terms of architectural descriptions. (Not so much with Reamde which was a non-sci-fi suspense thriller.) But the intricate descriptions of Seveneves almost always served a definitive purpose. Even if at times I felt the lengthy descriptions of minute orbital mechanics were less than thrilling, they almost always paid off, anchoring me in the physics and the challenges they posed, or allowing me to better grasp the enormity and complexity of things like the Great Chain.

Why did the descendants of the Seven Eves avoid interbreeding to such an extreme degree? While it is explained that Moira finds ways to mitigate the genetic problems of inbreeding, one would presume that as soon as there were sufficient numbers of humans that they would immediately start mixing with the other “families,” increasing the (incredibly small) population’s genetic diversity by traditional means. I understand that the Council of the Seven Eves left us with seven women who each had very strong and differing opinions about the kinds and character of humans they wished to spawn, but I don’t understand how such an ideological point of view (and we are led to understand that “Blue” is averse to ideologies) could have been followed so rigidly, except perhaps by the presumably indoctrinated descendants of Aiïda.

By the time people are sufficiently numerous and have divided themselves into orbital territories in the Grain Chain, it makes more sense that folks might tend to reproduce with others who are like them and in relative proximity – traveling from one part of the ring to another was doable, but not simple. It’s simply difficult for me to understand why such a strict adherence to seven distinct racial lines would or could have been maintained in the first few generations on Cleft.

What happened to the Mars expedition? I suppose we are meant to assume that whether they got to Mars or not, given the upheaval of the Break and the inability of the Mars mission to subsist for more than a year or so, that they were simply lost. Certainly, the people of A.5000 would have been able to find out whether a human mission to Mars had ever made it there, and it’s never mentioned.

What is the story of the Pingers’ Epic? How did they manage to change themselves so (relatively) quickly? How many of them are there? What kind of society do they have? Could they have communicated to the people of the Great Chain if they’d wanted to? It is all clearly a book unto itself, not that we should presume that such a thing will ever come into being. I suspect it’s one of those things that Stephenson is just going to leave there for us to wonder about. But given all we hear about how the Cloud Ark was more of a pacifying story for a doomed population than a genuine long-term plan, it does seem like the underwater gambit could perhaps have been not a Plan B, but a Plan A; the actual best hope for humanity that was better-designed and better-prepared.

President Julia Bliss Fletcher. It’s not entirely clear whether she was always cynical and conniving, but as I always say, one doesn’t become President of the United States without being at least partially sociopathic and messianic. Compound the unspeakable stress and pressure of leading a nation of humans that are all about to die, along with the loss of her own family, and the need to drop nuclear bombs on fellow humans, it’s easy to see how muted or dormant tendencies may have blossomed when the shit really hit the fan (or the Moon really hit the Earth).

That said, as the only successful unauthorized stowaway to Cloud Ark (I don’t count Sean Probst who had his own operation going and immediately sacrificed himself for the larger cause), I’m flummoxed by the leeway granted Julia by Izzy’s command structure. Certainly, bigger problems existed, and surely no one wanted to cause more grief and confusion by “jailing” the just-until-recently President of the Newly Pulverized United States. Still, it seems to me that her obviously violent and desperate route to the Cloud Ark should have led to far more scrutiny of her activities, and that she would face some form of justice for her (and call it what it is) crime. Perhaps none of that would have mattered, and she’d have caused the chaos that she did one way or the other. In a way, Julia was like a second Agent.

An Agent that allowed someone like Aiïda to really fuck things up. Of course with the population of all humanity reduced to eight, I can understand why she was allowed to remain free and alive, but I can’t help but think that considering all the horrible things she’d done, and her obvious hyper-aggressiveness and hostility toward the others, that she might have been considered too great a risk and too great a threat, and done away with before the regeneration of the species got going. Again, I get the need for genetic diversity, but it’s not as thought they really took advantage of that diversity, and who knew when she might snap and just kill everyone?

I also wonder why Moria couldn’t have found a way to carry on Luisa’s genetic lineage along with the others, perhaps with one of the other women acting as a surrogate. Seems a waste of perfectly good DNA.

And what the hell was the Agent, anyway? This is another one of those things that I’m comfortable not being told – it’s not a story about why the Moon blows up, but what happens next. But of course you can’t help but wonder if the answer will reveal itself throughout the entire book. It never does. Some poking around the web tells me that several folks theorize that the Agent is related to events in my favorite novel, Stephenson’s Anathem, which certainly could be the case. One of the mind-bending things about Anathem is how its multiverse setting could have tendrils into myriad stories. The way Julians are described in Seveneves remind me of the first “aliens” the people of Arbre encounter in Anathem, and if any race was going to make sure they got good seats on the multidimensional spaceship, it was going to be the Julians.

I was pleasantly surprised by how Stephenson made some of the characters so obviously analogous to known figures in real life. Doc Dubois was, to me anyway, clearly meant to mirror Neal deGrasse Tyson, and Camila was of course a take on Malala Yousafzai (though of weaker character than the real Malala, too easily overcome by charismatic personalities). The eminent scientist near the beginning to addresses the world at the Crater Lake event was probably meant to resemble a less-debilitated Stephen Hawking (and perhaps Dr. Hu Noah was as well?). And if Sean Probst wasn’t Elon Musk I’ll eat my hat.

I also think Stephenson often puts himself into his books (think Dodge in Reamde or Erasmus in Anathem), and it seemed to me that this time he was personified by Rufus. But that’s just a guess. I should say I don’t think Julia is meant to be an analog to Hillary Clinton at all: no one could accuse Clinton of being able to form a cult based on her charisma.

When Moirans “go epi” and experience changes in their phenotypes, to what extent are they really entirely different people? Kath Two is said to have “died” when the transformation to Kathree begins, but is that accurate or a kind of shorthand? They don’t eject all their memories, it seems, so perhaps it’s not dissimilar to the Trill on Star Trek, continuing on with new identities, anchored somehow with the memories of “another person” that you used to be.

Oh, there’s so much more. Will the Spacers, Diggers, and Pingers eventually interbreed? Who are the Owners? What is the full story of Sonar Taxlaw (perhaps the best-named character of all time), and what will her life be like now? Are there efforts underway to terraform Mars or other asteroids and moons? When do we get a Seveneves Sid Meier-style turn-based strategy game, and will it run on my current Mac?

And here’s a thing that strikes me about Stephenson more broadly. In all of the books of his I’ve read, as “out there” as his science fiction might get, one thing holds true: The aliens are always us. Be they from parallel universe, hiding in mines, adapting to the deep sea, existing in a virtual world, or simply an ocean apart in preindustrial times, we never need non-human extraterrestrials to “alienate” us. Humanity serves exceedingly well as its own threat, its own contrast, and its own focus of awe.

When emerging from the world of this book, I have a powerful sense of Earth’s fragility. Not just in the sense of what might slam into the planet, but of the permanence (or lack thereof) of the everyday objects around me. I have a sense of gravity as something not to be taken for granted, an ecosystem that is so battered and yet so resilient, and an entire universe that is such a relatively short distance “up.” The stark plausibility of this end-of-the-world scenario (like that of Station Eleven which I’ve also recently read) fills me with a kind of dread for how temporary our situation here on Earth inevitably is, and even if it doesn’t happen for millennia, how it really all could be taken away in one macro or microcosmic event. It made me want to hug my kids, not just for our shared precarious position in existence, but also for the incredible potential they possess to make things like orbital habitats for billions of people possible.

I didn’t want this book to end. I want much more of this story. To help alleviate that pain, I think I’ll dive back into Anathem.
