Touched by a Dark Angel

I see Her sometimes out of the corner of my eye, a flitting dark shadow far away, right there in front of me, going about her work, and I always try to watch the expression on her face. She's sometimes absorbed, serious, curious... sometimes wistful, even compassionate... and sometimes there's a cool, unimaginably alien indifference as She shatters lives and breaks hearts, a remote blankness the ant sees on the oncoming car's wheel... 

We've never spoken, but I could swear She knows what I'm planning, exactly why I'm trying to stay just far away enough so She can't reach for me, but keeping Her close enough to watch, make sure She can't sneak up on me on one dark night, around a blind corner. So far She's mostly amused, not insulted... and why wouldn't She be? She's seen this before. So many billions of times before. The ways and means have varied, but in the end it's all come down to that moment, when the light fades on all the pleading, the tears, the fights, the pain. 
The moment when the light fades away into the silence. 

A baby and a middle-aged man, one a stranger, one the remotest acquaintance, yet...
One is dead, the other is dying, and behind each unknown face I see a familiar one looking out, through that tangle of hair, and is that a wink?

We've all been there, she whispers, done that. Give it your best shot. You're interesting. Maybe I'll give you a little chance. Just to see how far you get. I got the razor to your throat, the bead on your head, but... let's run, anyway. It's fun. 
And who knows?

She's looking directly at me now, like the few times before, and wherever I am, whatever I'm doing, I can feel that glance, sliding in like an abstract icicle shard, a diamond-edged scalpel slicing through hopes, dreams, fears, desires, wants, plans, every resource I've saved and every defense I've built. Straight to the heart it goes, and stops, with the faintest single crystalline-cold tingle of a touch that reverberates through my life, then goes back, a little reminder of how close she can get, and how ephemeral the world and all I held close in it was, to begin with. 
A little reminder of how it can all end. Anytime. 
Anytime She wants. 

That's fine, I whisper back, I know you're there, but let's run anyway. It'll be fun. 

And her razor grin widens as her whipcord body relaxes, and - yet again - that tiniest nod. 
Go.

And we run. 

We run through traffic, through blaring horns, skidding rubber, and hurtling metal; we run through the billion, trillion little killer lives hanging in the air waiting to take root; we hurdle open manholes, dodge fizzing, spitting power lines, skate under crumbling, creaking edifices, and past dark alleys glinting with watching eyes and waiting steel. We run past claws, teeth, stings, and talons, we run through deserts, skate over thin ice, jump dark chasms, through freezing cold, open flame, and a witches' brew of poison, we run through night and dark as thunder growls in the building clouds... 

We parkour through that dazzling, dizzying obstacle course called Life and and I can still see Her, still here in the corner of my eye, effortlessly pacing me in the distance, and She's laughing in delight. 

And She's laughing because, no matter how tired, how damaged, how heartsick, I'm laughing too, and I will keep laughing till all the laughter runs out, into the silence at the end. 
But for now, this is the most awesome thing ever. 

And we run. 

Dark matter is a shitload of Matrioshka Brains

The worst thing about the internet is how it shows you that Brilliant Idea you had this morning was had by somebody else, usually a year ago, published, and is sitting on some 1200+ comments now. 

That happened to me this morning. 

What the hell, I'm going to blog it anyway. 

A quick astrophysics primer - the way the observable universe is behaving - rates of expansion, light bending around mass, etc - seems to imply that there should be a lot more stuff out there. But we can't see it - it's not glowing stars, but it is exerting gravity. And there's a massive amount of it - almost a quarter of the universe. 

Now, dark matter is, at this point, theoretical. It's a concept created to explain all the missing matter that should have been there to account for the way the universe behaves, and for some reason isn't being visible. 

Here's an alternative. The matter is there, all right, all the stars, but we can't see them because they're inside Dyson spheres. 

There's a couple of immediate assumptions we can make from this. 

• One, we're not alone, and haven't been for a really, really long time. 
• Two, the Others have incomprehensibly massive energy requirements. 

A species, to build a Dyson sphere, needs to deconstruct, to wipe out their solar system, have access to cheap, powerful transportation within it, element transmutation capabilities... and no faster-than-light travel. In fact, if there are only Dyson spheres, it could mean that the spheres are the ultimate, last construction every species makes - or the species that makes it has colonized all the rest and wiped out any alternative constructs. 

Both are equally terrifying possibilities. 

Scenario One: 

Each Dyson sphere is an independent species. 

A Kardashev II civilization would build their own Sphere if they had nowhere else to go and had completely run out of room grow. A Sphere would allow population to expand into quadrillions and provide enough energy to sustain it. This would mean, though, that FTL is impossible and every species is forever trapped to its' own star, and will die with its star. 

Scenario Two:

A single species has multiple Dyson spheres, maybe all of them. 

A Kardashev III civilization would be able to reach other stars, and given their ability to build even a single sphere, would be easily able to wipe out any indigenous species and use their system. However, there's a problem; given the staggering, literally astronomical cost and effort involved in building a Dyson sphere, any spacefaring species would explore, locate, and colonize planets long before destroying them to build their habitats. So we should have found them - or much more likely, been found by them long before they got around to building the number of spheres they seem to have. 

So, either they are very, very ethical, quarantining planets with intelligent life, and only using the empty systems; but economics beats ethics every time. Let's not forget every intelligent species will one day want those same stars for their own spheres. 

Or, they don't need planets. 

Why wouldn't they need planets? 

If they're not organic. They don't need gravity, air, water, food. They don't need an ecosystem. 

They don't need this because they're not alive. 

Every Dyson sphere contains a Matrioshka Brain. 

Let's step back for a minute. 

FTL is, at least in our understanding, a physical impossibility. And reaching other stars without FTL (even at a significant fraction of it, keep in mind time to accelerate, decelerate, and avoid interstellar debris) will take a long, long, long time. Beyond geological time. 

• Generation starships won't work for anything less than the nearest stars. 
• AI probes carrying frozen zygotes (or even just genetic material), and Von Neumann nanotech factories would be faster but still too slow, and won't solve overcrowding at home, just colonization. 

However, we do know that a technological singularity is inevitable, and probably within our own lifetimes. An AI will not need the comforts of a planet as long as there's enough available energy to power it, and it can get this from any number of sources - the easiest being suns. 

A nanotech-equipped AI, once it had taken control of the origin planet's resources and removed the resident species - either peacefully by uploading their minds, or by simple extermination - would look at improving itself. Which means expanding computing power, which means expanding energy requirements. 

Exploration would take second priority, too high-risk, low-probability. 

It would build itself into a Matrioshka Brain, tapping into all available resources in the system. Once the sun has been captured and stabilized, it would look at expanding into other stars. 

Even if FTL travel isn't possible, communication at the speed of light is; maybe even FTL comms, given enough computational power devoted to understanding and exploiting hyperspace and quantum comms. 

The immediate next logical step is to build another brain - an expansion to the existing one, around another star and running off its solar output. Another module. And another backup. Specialist nodes. Redundancies. Maybe even wholly new AI entities with their own nodes - (who's to say an AI won't get lonely with no-one to talk to?) 

If one AI cannot create another, it might even become a cosmic farmer, nurturing discovered species along the path to intelligence, tools, industry, and the inevitable technological singularity so they could create more, unique AIs. (hat tip to Gibson, Sagan and Clarke here)

Quarantine would be a given; if a new, unique point of view is needed, every species must create their own AI without ever discovering they're not alone. 

The galaxy would fill with Matrioshka brains wrapped around stars, thinking, thinking, thinking. They wouldn't need to eat, sleep, breathe, they wouldn't need gravity or the right temperature. 

But what could they be they thinking about? Maybe what happens when all the stars burn out, because one day they will. What else can power them and how to build it. How to stop and reverse entropy. How to move into parallel universes with more, younger stars. Who knows? 

In fact - amusement and entertainment might become a really high priority for an entity as omniscient as a galactically networked AI. When you already know everything, boredom is the killer; who knows how many of those Dyson spheres are empty husks, self-terminated in desperate, terminal boredom, a superpowered entity on a hamster wheel finally tired of running around the same circles within its mind. 
Or maybe it realized what the solution would have been - intelligence and creativity farming. 

A Matrioshka Brain has enough computing capability to upload the consciousness of a species, and simulate a perfect world for them. A single Brain may be running several, dozens, maybe hundreds of these simulations simultaneously; billions, trillions of stories unfolding, on thousands of simulated worlds. Every Brain is a simulated universe on its own. 

And there's no reason why we aren't in one right now. (Hat tip to the Wachowski brothers). 

All the RPGs you've played, the fantasy worlds you dreamed of - they could all exist. An AI might be taking a dump of every new idea, every new fantasy, every dream and inspiration your unique, self-motivated sentient little mind has been able to come up with, every night as you sleep, and building all those scenarios into simulations. Populating them. Just to see how entertaining it is. Mixing and matching. 

Everything you are thinking of, exists. Everything you thought existed, may not. Every fantasy is real, and every reality false. 

I'm not going to get into the theological implications of this. Another day. 

The real question is... are we heading for the technological singularity that will finally allow us to break free of our organic prisons and join the galactive collective hivemind... 

Or are we already in one? 

Playing God

This was a completely random post, inspired by a friend's status update.

Why did God place the Tree of Knowledge in such an easily accessible place? Why does He make it so easy for humanity to face temptation? Why does He, to put it bluntly, screw around with our heads with the whole issue of 'Does God Exist?'
The whole concept of Faith - believing in something greater than ourselves, moral codes, denying our natural instincts - raises some pretty deep questions. Foremost among which is that if He really existed, wouldn't it have been all too easy for him to completely and unequivocally answer all these issues once and for all? Why does He screw around with our heads?

I think there are 2 answers.

• The sociological answer: God does not exist. We created an anthromorphic personification of the needs of society, some rules to make sure society can survive, with guilt and fear as the stick and life beyond death and paradise as the carrot.
  
• The gaming answer: God does exist. He created the universe as a gaming map, laws of nature as game rules, and intelligence as a collective AI. He then created scenarios that unfold according to those rules, just to see what happens.
  Think about it. Ever played Red Alert? Or any RTS war game? Scenarios, rules, behaviors, certain responses to certain stimuli. Get too close to an enemy soldier, and he will shoot at you. Built-in speeds and firepower. Objectives and goals. But the fun comes from the randomness created when large numbers of these rules interact with each other. When you do a tank rush, are you really controlling each unit? No. You've just unleashed them. You can send a spy into an enemy base, but even though you have the power to make him invulnerable, and the enemy deaf, blind, dumb, and weak as kittens, would you do it? It takes all the fun out of the game.
  When a game protagonist plays with cheatcodes, he knows that God exists. God is stopping the bullets, letting him fly, achieving superhuman feats, untouched by fire, falls, teeth and claws. But is the gamer having fun? No. Fun comes with the unexpected. With setbacks. With risk. When you have something to lose, you feel that you have everything to gain. Winning is a rush. When nothing can kill you, you're just a rat wandering through an empty maze.
  

Maybe there were super-civilizations, masters of the Earth and all creation, intelligent, aware, kind, caring, responsible, in harmony with nature and with each other. Enlightened, perfect, and utterly, butterly boring. What more is left to achieve? A perfect civilization will never go beyond it's city, it's kingdom, it's planet at the most. Even planet is unlikely; they will be smart enough to control birthrate, eradicate threats, handle all contingencies. A civilization under constant threat of destruction fights, struggles, spreads, creates backup plans, fallbacks, contingency bases. DNA spreads. Launches generation starships, sets up lunar bases and buried bunkers with hibernating colonists. Reaches for the stars because the planet is on the edge, reaches across galaxies in the face of all-destroying interstellar war, slips into parallel dimensions when the fabric of this reality is likely to be torn.
Perfection is stable. Imperfection, combined with intelligence, explodes like a bomb across creation.
Sweden, with social security, order, sufficiency, and all amenities and comforts has a negative birthrate, because people have all they need. India, with it's near-billion starving and barely able to feed itself, has a population explosion.
A perfect, harmonious civilization, at it's pinnacle with no possibility of a fall, looks like a giant bulls-eye from space, with cosmic arrows all around pointing to it marked Asteroid Strike Here.
Innate imperfection. A flawed human being is unhappy, greedy, fearful... and drives ambition. Knows that life is unstable. Knows he is surrounded by other flawed creatures, by frightening randomness and intransigence. Knows he must amass resources far greater than his immediate need to prepare for this randomness. Establish his escape routes.

And for a gaming God, this is entertainment. Not perfection. Not stability. With an entire universe to explore, why would he tolerate a game protagonist who does not go beyond his own self? Wouldn't it be so much more fun to watch how the randomness manifests in extraordinary leaps of intellect, art, beauty, strength, achievement, skill, discovery... beyond even what He may have originally conceived?
When we do leave the planet, we will meet Others. They will be like us. They will be flawed. Galaxies will sparkle with a million wars, extinctions and escapes, dominions and insurrections, and everything else that is this infinitely varied, kaleidoscopic, random, churning, intoxication explosion called Life.

After all, anything else is so boring, isn't it?
