Having recently finished Tsutomu Nihei’s masterpiece,
Blame!, I wanted to talk a bit about the various aspects of the world
Blame! takes place in. They’re just comments about the manga and are not necessarily part of the manga canon. The following discussion contains spoilers on the story of Blame, so if you wish to read the manga and haven’t done so, skip this entry of mine until you’ve read it.
Here we go.
Beyond people
In the lower levels of the City where people still live, time and physical constraints have separated groups of humans from each other. This has led to a branching of peoples and the creation of human sub-species, some so radical that they become transhuman, no longer attaining human form. Some radical evolutionary (or devolutionary) branches of the series may be the organic creatures we encounter later in the series, or in the spear-wielding ‘skivvies’ that we encounter in the earlier volumes.
Through centuries, maybe even millennia of natural selection, humans in different levels of the City develop different traits. The Electro-Fishers are noticeably short - a dwarf race of humans, while the race where Cibo comes from is noticeably taller than the rest of them (and even then, one of the races that Killy encounters earlier on is taller than even himself.) Varying levels of gravity in the City may have influenced this.
(Ironically, it seems that the Planters, people inside Toha Heavy Industries, were of normal height, indicating a possible Earthlike gravity inside THI and a higher gravitational pull outside THI, where the Fishers live.)
It can also be said that the Silicon Creatures are a special offshoot of humanity, breaking through the barrier of purely organic evolution into something techno-organic. In one of the alternate realities of Blame! the Silicon Creatures have evolved into newer models; it’s not a long shot that the Silicon Creatures of this world may evolve along the same lines.
And there is a third possible line of evolution – transcending physical form and evolving as data. Personally I cannot fathom to what lengths a data-form can become when it evolves, since I know data is currently static, non-evolving unless converted into something else forcefully. But maybe in the future the time will come where data itself can evolve into new data. Of course, I think that along with that, hardware and software will also evolve to adapt to the new data, or vice versa.
The Netsphere
In the world of Blame! the Netsphere is a utopia of sorts, a place for the chosen few – and also a place where one can control base reality. It is also a place where people exist as data, connected via some sort of interface. In the manga, the type of interface is uncertain, but it seems to be a direct link to the brain (with the Net Terminal Genes as a method of authorization) or a transference of one’s personal data.
The Netsphere is the Eden of the Blame! universe. The Safeguards prevent access to it; the Silicon Life have the same purpose, for different reasons (for a human in the Netsphere invalidates the Silicon Life) and some, like Davinelulinvega, wish to access it, even if it is forbidden.
It seems to me like the Netsphere is an insanely advanced version of the Internet. Virtual worlds like this have been postulated before in science fiction works.
What if the Netsphere is an Omega System, and base reality is merely simulacra nested within an even larger virtual reality, and our tangible reality may not exist anymore? It would explain a few things, namely how the Netsphere manages to control base reality and the immense logistical requirements needed to create something as gargantuan as the City. It would also explain how structure conversion towers and Safeguards manage to manipulate matter.
Well, maybe that’s thinking too much into it.
Megastructure
The structure where Blame! takes place is postulated to be a huge, layered Dyson Sphere, whose dimensions are approximated to take it to at least the level of the orbit of Jupiter (!) this fact alone makes the City hundreds of millions of miles in diameter. Some have thought that the materials needed to construct something of this magnitude would encompass several solar systems. The number of levels of the City may number in the millions, although as the levels go higher, the space it occupies also becomes larger, thus, only a few levels may exist. It has also been theorized that the construction of the Dyson Sphere has completely used up the entire planet Jupiter, if not the rest of the planets as well, including Earth.
It may be possible that the City is not a complete Dyson “Sphere” in the perfect sense; it may be that the sphere “grew” out of Earth and involved itself around the Sun in a different way, a Dyson “Wedge” if you may. That structure would involve considerably less materials than a full-fledged Dyson Sphere (although the amounts involved would still be pretty staggering.)
The Builders, whose chaotic actions made the City this way, create things out of seemingly nothing. The fact that the Builders have been known to teleport rooms or entire structures from one level to another may indicate that they may have some sort of transference or energy/data conversion technology we haven’t developed yet.
If base reality is a virtual reality, then logistics will not become a problem, only data handling capacity, and I think with the advanced computers of that time will be able to handle it.
The Passage of Time
Although you will probably breeze through all ten volumes in a few hours, the story of Blame! spans hundreds, if not thousands of years. Travel through the City takes enormous amounts of time, especially if one is on foot, and it seems that that is, for the greater part of the manga, the only mode of transportation Killy has.
Even with assistance, it takes months for Killy to traverse just one Megastructure. That’s one among thousands of Megastructures – and he has to go to the edge of the City, a trek millions of miles long. The other thing is, it’s not just a trek forward, it’s a trek upward, in essence, Killy is climbing upward slowly a structure millions of miles high.
Even the large storage room the size of Jupiter would have been a long, long walk (although the elevator ride up would have been much, much higher.
It is not known how much time Killy takes in traversing the levels between chapters 1 and around 7, before he meets Cibo. It could have taken him centuries before he reached Cibo’s level.
For civilizations to have developed at that level independently also takes time, and countless generations of people and memory would have evolved since then.
Memetic Degradation
With time, all memory fades. Like the Net Terminal Genes, the Memes of the Characters of Blame! also degrade over time. The first chapter of the manga is quite telling. Killy and the person with the dog (who we now know is Iko from an earlier age) do not know what a book is, much less what the “Earth” is. With the passage from time and mankind’s alienation from Earth, it seems that people have lost the memory of what Earth is.
Another form of Memetic degradation stems from the admission from some of the other human sub-races that they have lost the ability to read languages, simply because their ancestors had no need for the old language or they developed one on their own. From memetic degradation comes a reset of sorts, leading to the creation of new cultures. The Fishers have forgotten the purpose of Toha Heavy Industries (it was a ship carrying immigrants to space) after having lived outside for so long and have established their own culture. Also, there are no Fishers alive with the knowledge on how to make their weapons (probably carried over from the Planters)
It’s possible that after being separated, the Fishers went into a mode of pure survival, where their previous knowledge slowly died out after generations. When they were self sufficient enough to snap out of that mode, it was too late – their memes had already degenerated.
Only persistent memes remain strong; those that aren’t, and are not connected to tradition (in contrast to how the African Bushmen or any other ancestral tribe manages to keep traditions alive even by word of mouth) pass into legend, then obscurity, then memetic destruction.
Transcendence
Cibo is one of the most interesting characters in the series. She changes form and goes from body to body as the series goes on.
One can ask, even in the beginning the Cibo we know in the series was just backup data compared to the actual Cibo who conducted the Artificial Net Terminal Gene experiment. Is she the ‘real’ Cibo? Is the Cibo in Sanakan’s body still Cibo or a new being? What defines one’s ‘self’ in the world of Blame? How will physical bodies be of importance in this world? If one accesses the Netsphere, what will happen to that body?
Physical reality like ours and the 'reality of data' in Blame is still technologically far away, but in the future, who knows? We might find the secret to near immortality one day.
Living On
In closing, one of the essences of Blame! was the drive of humanity to propagate itself, to survive even in a cold and unfeeling world. All of the characters in the series were fighting for their own survival. For that, the Silicon Creatures sought Chaos, Cibo wanted escape. The Governing Agency wanted order. Who would survive till the end? Who will prevail? You'll have to read the manga to find out...
