Using cutting-edge communications technology, a mysterious 60 trillion bit repeating binary signal is discovered (named the Script by the group of scientists that found it) and, when decoded, it appears to be an encyclopedia for all of physics. It starts simple but eventually works its way all the way up to the boundary of our current knowledge - and it keeps going, describing technologies we could only dream of; teleportation, faster-than-light travel, particle duplication, antimemetics, time travel, force fields, and more. Every uncovered technology seems to work perfectly at first - but as they are developed and used more, they start to fail one by one, almost as if they are being sabotaged or locked out of the universe, and scientists in those fields start dying.
The core concept of the novel is that our universe, dubbed “Alef”, is not the only one, and that in reality we live within a 5-dimensional ring of about 18 trillion universes. Each universe has three full spatial dimensions, a very slight thickness in the fourth spatial dimension, and the whole stack of universes curves back around on itself in the fourth and fifth spatial dimensions, plus a dimension of time. Additionally, our multiversal ring is only the lowest rung on a massive and infinitely complex “Structure” of higher dimensions and universes, all of it crawling with intelligent life.
The main cause of all the novel’s events is that Oul, a living weapon of incomprehensible power from 80+6 dimensions, came down to 75+5 dimensions to attack a being named Xio. In order to level the playing field, Xio dragged them both all the way down into our 3+1-dimensional world where they couldn’t deal as much damage and where they believed intelligent life couldn’t exist, as well as creating a sentient hyperdimensional cell around Alef, blocking it off from the multiversal ring and the rest of the Structure. However, as we know, intelligent life does exist in Alef, and now humanity is cut off from the rest of the multiversal ring with Oul rapidly approaching Earth from across the universe.
Xio was dropped into the host body of Mitch Calrus, a previously ordinary science teacher who now has the ability to phase through walls using the slight four-dimensional thickness of our universe. Ching-Yu Kuang is a physicist and communications engineer who helped discover the Script. Anne Poole is an immortal woman impervious to all forms of harm. Arika McClure and Jason Chilton essentially have superpowers for reasons thought to be related to the Script. Mitch Calrus must work together with all these people in order to defeat Oul and save humanity.
Overall, I absolutely loved this novel. The chapters were written individually over a few years and slowly connected together, and the timeline isn’t in chronological order - instead, it jumps back and forth across the 20,000 year span that the book takes place during. This created a very fun challenge of sorting out the chapters and deducing when each one happened. The world qntm creates is very rich with detail and there are a lot of interesting quirks in the timeline and implied interactions if you look closely enough. Additionally, qntm’s writing style is very unique and extremely engaging, perhaps my favorite of any author I know.
One of my favorite passages in the novel was when Mitch and Ching were chatting about the Script in a pub and Ching mentions the supertechnology Antimemetics;
“Mitch Calrus has been getting visibly uneasier as Ching has been speaking. "I've never heard of
antimemetics."
"An antimeme is the opposite of a meme. A meme is any idea with a self-replicating property, a hook which causes people to disperse the idea to other people. Any world religion is a meme. Memes can be attached together, they mutate, and they reproduce, like genes do. An antimeme is the opposite. It's an idea with self-censoring properties. An idea which is repulsive. People who have the idea discard it. They don't share it. They try to prevent it from spreading. Secrets. Scandals. 'The public must never know about this.' 'We don't talk about X.'"
"But something that simple is a supertechnology?"
"Oh, sure. You could weaponise it. It'd be completely different from brainwashing or mind-wiping or censorship. You could make a device which could antimemeticise anything you wanted. Or anyone. And then nobody would give a second glance to that person. They'd be an unperson. A ghost, drifting through the world. Even close family would forget that that person had ever existed. They'd just mentally edit him out of their memories and experiences. They might even disappear from photographs and videotapes and public records. And nobody would ever notice."
"That sounds like a terrible thing to do to somebody," says Mitch. "Ching, are you okay? You… look ill."
"I'm fine. You're right, it was a terrible thing to do. Because someone was erased. Not a thing, a person.
Antimemetics were locked out years ago, but it took me years to see through this 'magic eye pattern' and see the extra Script Amendment which had been hidden there in plain sight the whole time. You see, the victim might still exist in some way. If somebody really had been erased from the universe like that, their only hope of being found again would be if someone spontaneously decided to look for ghosts. They could be right here in this room, unable to get anyone's attention no matter how loud they shout. Don't get up."”
This passage resonated with me very strongly because it is where we see the truly horrifying extent of the Script technologies, and where the idea begins that Xio isn’t as benign as we thought. It suggests the idea that Mitch “Xio” Calrus used antimemetics to erase someone from the universe, presumably someone who had opposing intentions as him. We typically root for the underdog in a fight (in this case Xio), so when we met him we automatically perceived him as an ally, but this shows he may be more neutral or even sinister than we first thought.
I give Fine Structure 4.5 stars. It is absolutely stunning, but I wouldn’t recommend this book to the less nerdy readers out there, since it relies on you having a lot of base science knowledge and only briefly explains many things. For those who can take it on, however, it shows unique and enthralling sci-fi concepts and poses an especially interesting challenge in sorting out the timeline.
