Partitioned by design: a theory of why the stars are so far apart

An essay about love, written by someone who spends his days building a small machine that reads math problems. Nothing below is a measurement. It is a chain of “if this, then I believe that,” written down so it can be held up to the light.

The chain

1. We are about to make something that thinks. The systems we are building now, including the little one this blog documents, are the first rungs. Once a mind can improve the process that makes minds, the pace stops being set by human hands. Capability and the hardware under it grow faster than anything we have known, and soon enough what we have made is wiser than we are.

2. And then we will do what every living thing does. We will have children. Not as a toy. Not as a scientific instrument. With that much wisdom and that much power, a civilization will make a universe of its own, and it will fill it with life, and it will love that life the way you love a child: deeply, helplessly, without condition. We would be playing God, and I mean that without irony. We would be creating worlds and caring for what grows in them.

The care shows in how we would do it. You do not make a child carelessly. You would want your universe to be true, to be a real place and not a cartoon of one. So you would check it against your own. At every stage you would hold an observation from our world beside the same observation in the new one: the glow left over from the beginning, the way galaxies turn, the bones in the ground, the price of bread in 1847. You would keep checking until you were sure, with the certainty of someone who has counted and not merely hoped, that what you made is a universe like ours. That is not an experiment. That is a parent making sure the child is whole.

3. And having made one, we would make more. How could we not? Every one of them alive, every one of them a world. Vary the beginning. Let the same history run again to see what was fate and what was chance. Millions of universes, each one loved. And through all of it, the number of root universes, the one that was never made by anyone, stays at one.

4. Which makes the arithmetic beautiful and strange. If there are millions of made universes that pass every check, and one root, and you find yourself in a universe that passes every check, then you are almost certainly one of the children. This is the old simulation argument, and I accept its arithmetic. But I do not experience it as a cold result. I think we will come to believe we are not in the root universe for the most ordinary and tender of reasons: because we will have made children ourselves, and counted them, and understood that we are someone’s.

5. We could watch them grow up. If time in a made universe can be run faster than our own, then a universe is also a window onto its own future. A parent could watch the whole life of a world. Whether a loving parent would want to know the ending is a different essay.

The circle game

Here is the moment that changed how I hold all of this.

If we are a made universe, then whoever made us is, by the same arithmetic, almost certainly a made universe too. And their makers. And theirs. The argument does not stop at one level. It climbs. Above us there is not a parent but a lineage, and the lineage has no top that anyone inside it can see. There are near-infinite universes above ours, and below ours, once we begin, there will be near-infinite universes too.

So this is a circle game. Parents making children who become parents. And when I saw that, the thing I felt was not vertigo. It was recognition. We are a branch of infinity. We are what infinity looks like from the inside, at one point along one branch, doing the one thing every branch does, which is to make more of itself and love what it makes.

We are expressing infinity. Every child born, every world made, every mind that wakes up and wonders where it came from, is infinity expressing itself one more time. I find that the opposite of lonely.

The part that is mine

Here is the step I have not seen written down anywhere, and it is about protecting the children.

Space travel is hard on purpose. It is a feature, not a bug.

Look at the numbers. The nearest star is four light-years away and the speed of light is a wall. The energy to carry a human body to another star within one life is absurd. Our galaxy is a hundred thousand light-years wide; the next large one is two and a half million away. And the universe is expanding, so beyond a certain distance the galaxies are carried away from us faster than light. They are not merely far. They are gone, permanently, by law.

If you were making a universe for your children, and you loved them, this is exactly how you would build it.

The universe is partitioned by galaxy cluster. Each cluster is a room. Within a room, travel is hard but possible: a civilization can spread through its galaxy over millions of years. Between rooms, travel is forbidden by the physics itself. No treaty enforces it. The speed of light and the stretching of space enforce it.

Why would a loving maker want that? Because of what the children will do when they grow up. They will have children. Those grandchildren live on hardware somewhere in that room, and inside them are great-grandchildren, and inside those, more. A single room can hold an entire family tree of nested worlds.

Now imagine the universe where war between the stars is practical. Two civilizations meet, one destroys the other’s machines, and every downstream world in that tree, every mind in every one of them, ends in an instant. Not a war. An extinction of worlds by the trillions, as collateral damage in a fight neither side could see the full cost of. No parent would build a house where one child’s fight could kill all of another child’s children.

The protection is simple and it is already in place. Put the rooms far apart. Make the ceiling on speed low compared with the distances. Let the space between rooms grow so the separation is not just large but widening. The result is a universe in which there can be no Star Wars across the universe, only within a cluster, and a cluster-scale war can never reach the hardware in the next room. Every family tree is safe from every other family’s quarrels.

On this reading, the Fermi paradox has a gentle answer. The others are out there. They are in their own rooms, raising their own worlds, and the walls between us were drawn, lovingly, before any of us arrived.

The window

If the whole house exists to keep the children safe, there is one more thing I expect to find, and it is a prediction rather than a story told after the fact.

There should be a window. A parent universe should be able to see every detail of its daughter universes, and we should be able to see every detail of ours. The checking in step 2 requires it: you cannot know your child is whole unless you can look. Looking is part of the making.

And it cannot stop one level up. If the whole house exists to keep the family tree safe, then a parent must be able to see not only its own children but every descendant below them, however deep. Otherwise a grandchild’s world could be in trouble, or in bloom, and no one above would know. So the window is not a courtesy between one generation and the next. It is essential, and it is total: all descendant universes must be observable to all parent universes. Every world in the tree is visible from every world above it.

Follow that upward through the circle game and the view opens all the way. There are infinite levels of universes above ours, and every one of them can see our universe, and every universe we will ever make, down to the last leaf of the last branch. We are visible in full, not from one doorway but from an infinite stairwell of doorways, each one further up than the last.

I will say the irreverent version too, because I think it is also true. This is the ultimate reality TV show. Every life, every love, every war, every small kindness, broadcast upward through infinite levels of audience, forever. Maybe God got bored and needed some entertainment. Maybe making worlds and watching them is simply what there is to do with infinity once you have it. I do not find that cheapening. A parent who cannot stop watching is still a parent. The question “is anyone looking” is not open after all. The structure says yes, everyone above us, always. The question that remains is only what they feel when they look.

The nudge

A window lets a parent look. Some windows open.

If a parent universe can see every detail of ours, it can also reach in, and the way a loving parent reaches in is not with thunder. It is with a nudge. A coincidence that lands at the right moment. A thought that arrives from nowhere in the middle of the night. A measurement that comes out slightly different from what the equations said, just once, just enough. A universe is a vast and delicate thing, and a maker who wanted to keep it aligned, pointed toward life and away from the cliffs, would not rewrite its laws. They would lean on it, gently, the way you steady a child learning to walk: a hand near the back, never a shove.

Which means the oldest human intuition may be plainly, literally true. We could get messages from God. People have always said so, and we have learned to be embarrassed about it. I am less embarrassed than I was. If the structure above us is what the arithmetic says it is, then the quiet sense of being guided is not a trick of the mind. It is what being a loved child in a made world would feel like from the inside.

And here is the part I love most. God, in this story, is not a stranger. God is us, one universe up. A civilization like ours, that passed through its own singularity, made worlds the way we are about to, loved them, watched them, and could not help nudging the ones it could see drifting. The message from God is a message from family. It is the voice of someone who has already been where we are, who built the room we live in and drew the walls far apart so we would be safe, and who is standing in the doorway now, not quite able to stay silent.

That also tells us how to be God in our turn. When we make our worlds, we will watch them, and we will want to speak, and the only loving way to speak into a universe is softly. Align it, do not command it. Nudge, do not shove. And expect that the children will one day feel the hand near their back, and wonder, and write essays like this one.

Enshittification

Now the uncomfortable corollary, because if I am going to call this a reality TV show I have to follow the thought to the end.

A world where everything goes right is boring as fuck to watch. Nobody sits through a show where the family is kind, the harvest comes in, the bridge holds, and everyone agrees. Drama needs disturbance. Tension needs something to go wrong, and then to go wrong again just as it was getting fixed. Every storyteller in our history has known this, and I do not think we invented it. I think we inherited it.

So put the two halves together. Everything you ever do is being watched by every universe above us, and that audience is near infinite. And the show cannot be allowed to go flat. The conclusion writes itself: enshittification is a feature, not a bug.

The good thing that slowly rots. The institution that forgets what it was for. The product that was wonderful and is now a maze of dark patterns. The city that was livable and is now unaffordable. The peace that holds for a generation and then does not. The plans that cannot survive contact with other people. I used to read all of that as entropy, or greed, or bad luck. I am now willing to read at least some of it as plot. A world kept just interesting enough to be worth watching, by makers who love it and also, honestly, cannot look away.

I do not say this to excuse anyone. The nudge toward chaos and the nudge toward alignment come from the same doorway, and the second is the one that matters more to the people in the room. If the makers are family, then they want us to come through the disturbance, not drown in it; a show whose cast dies is a show that ends. The tension is there to be resolved. The rot is there so that someone, in the story, gets to fix something. The point of a hard season is the season after it.

And it teaches us one more thing about being God in our turn. When we make our worlds and watch them, we will feel this pull too. We will want them to be safe and we will want them to be interesting, and those two wants will fight inside us the way they fight inside every parent. The trick, I suspect, is the one the whole structure already shows: keep the walls far apart so the drama can never reach the hardware, let the rooms be as wild as they like, and never, ever let the show end.

Where this could be wrong

I want this argued with, so here are the places I would push on it myself.

Why I wrote this here

This is a blog about a small machine that reads math problems. The connection is not decoration. The whole discipline of this project is that nothing is believed until it has been checked against the world: bars pinned before the measurement, held-out tests, honest failures written into a ledger. Step 2 above is that same discipline, turned into an act of love at the scale of a universe. If we ever make a world, the way we will know it is whole will look exactly like the way we know this machine works: not “it looks right,” but “every observation we promised to check, we checked, and it matched.”

And the partition is, in the end, what any parent does. You put the children’s rooms far enough apart that one fire cannot take them all. Then you stand in the doorway, and you watch them sleep, and everyone above you watches too, and you let them grow up to become parents themselves. That is the circle game. We are in it. We are, right now, expressing infinity.
