Let’s begin with the left-handedness, because everything else will make even less sense if we don’t.
In Mirror-World, the overwhelming majority of people are left-handed. Not a quirky statistical outlier, not a slight preponderance — the overwhelming majority. Scientists who have peered through the portals and attempted to count hands have emerged visibly shaken, clutching their clipboards to their chests like talismans, muttering things about sample sizes and confirmation bias and whether they still believe in a God who would permit such an asymmetry to exist. They are almost certainly fine. Probably.
The handedness, however, is not the unsettling part. The unsettling part is the distances.
In Mirror-World, everyone is exactly half as far away from you as they appear to be. Pause with that for a moment. Let it do whatever it needs to do to your sense of spatial reasoning. What this means — and there is a formal mechanism here, the Inverse Square Law, which has the particular quality of a mathematical principle that sounds made up but is in fact devastatingly real — is that you are operating at approximately four times the collision risk compared to your own world. Four times. The person who appears to be across the room is, spatially speaking, directly beneath your elbow. The stranger who seems to occupy a comfortable social distance is, in the most literal geometrical sense, already inside your personal bubble and has been for some time. And the farther away someone looks, the closer they actually are. Distance, in Mirror-World, operates as a kind of aggressive hospitality. Go far enough away and you will arrive inside someone’s skeleton. And, what kind of twisted freak would welcome such a thing?
Here is where it gets genuinely deranged.
Collisions in Mirror-World are statistically no more common than they are here. Not slightly more common. Not marginally elevated. The same. The physics screams for carnage. The mathematics demands a civilization of perpetual bruising, a society in which every trip to the market is essentially a contact sport. And yet: nothing. People just sort of… don’t bump into each other. They navigate their half-distance world with a fluid, unconscious grace, moving around each other the way water moves around stones, as if the entire population had collectively agreed to ignore the Inverse Square Law and the Law had, with surprising graciousness, agreed to look the other way.
No one has explained this. Centuries of scientific inquiry have produced exactly nothing useful — a monument of bafflement, a cathedral erected in honor of not knowing.
Now. The portals.
Nobody has successfully passed through one. This is the first thing you need to understand about the portals — they are, in every meaningful sense of the word, a tease. They present themselves as entirely transparent, as crystalline and passable-looking as a window on a spring morning, practically whispering come through, come through, and then they permit absolutely zero passage. What they permit instead is observation. You can look in. The inhabitants can look out. That’s the whole arrangement, and it functions with the bureaucratic finality of a visa application denied without explanation.
The portals, incidentally, appear silver. Not transparent-but-sort-of-hazy, not clear-with-a-slight-tint — silver. A color. A color possessed by an object that is, by all documented physical measurement, entirely transparent. How a substance with no opacity achieves the property of color is a question that has driven several promising researchers into careers they had not intended to pursue. Insurance, mostly. Real estate. Fields where the answers, however disappointing, at least stay answered. Yet, ask anyone “What color would you say that portal is?” They will invariably answer “It looks silver to me.” Bizarre.
Do not attempt to think too hard about this. A person could go absolutely, irreversibly, clinically unwell thinking about the silver transparency of Mirror-World portals. Some have. We don’t talk about them anymore.
What we do talk about — whisper about, really, in the way you whisper about something embarrassing that is also somehow your fault — is what happens when someone tries to cross through. You’re blocked by some unknown force. Try too hard and the portal, in response to the attempt, shatters. And when it shatters, the crosser receives seven years of bad luck. The mechanism by which a parallel dimension enforces this sentence across the dimensional boundary into our world is, like everything about Mirror-World, is not understood. What is understood, in the loose conspiratorial way that most Mirror-World knowledge is understood, is that the inhabitants must practice a sort of Voodoo, that they are vindictive in the specific, focused way of people who have far too much free time on their hands, and that they do not appreciate having their portal infrastructure destroyed.
The free time issue is crucial. In Mirror-World, all written language is printed in reverse. Every book, every sign, every cereal box and bureaucratic form and legal notice arrives mirror-imaged, rendering it, for all practical purposes, unreadable by anyone without a mirror, considerable patience, and a willingness to accept that the universe is having a laugh at their expense. The result is that Mirror-World people simply do not read. They have, by force of dimensional circumstance, been liberated from the written word, and they have filled this newly vacated expanse of time with what turns out to be their primary cultural pursuit: watching us.
This is not metaphorical. This is not a commentary on parasocial consumption or the attention economy, though it absolutely is both of those things. The inhabitants of Mirror-World have developed a robust pastime built entirely around loitering near portal rooms, waiting for one of us to wander into viewing range, and then either staring with a focused, unnerving intensity, or pretending — with theatrical unconvincingness — that they haven’t noticed us at all. The latter is considered high comedy in Mirror-World. You can always tell when they’re doing it because they keep sneaking little sideways glances through the portal, the same way a person tries to discreetly observe a minor celebrity at a restaurant and convinces absolutely nobody that they’re not impressed by such things.
The truth, insofar as anything about Mirror-World qualifies as truth, is this: they are hopelessly, helplessly, somewhat pathetically in love with us. They have always been. They arrange their days around the possibility of our appearance. They perform indifference as a form of flirtation. They do not write, do not collide, do not obey the Inverse Square Law, and they spend the resulting surplus of time and psychic energy absolutely besotted with a version of reality they can see but never touch.
What exactly is this strange world? It’s an enigma, wrapped in a riddle, surrounded by soft, gooey caramel. I believe it’s safe to say that nobody really knows. However, I do have my suspicions.
Mirror-World people are strange. But then again — and here is the part worth sitting with, the part that makes the portal’s silver transparency feel almost appropriate — they are, in the most technical sense, us. Reflected. Reversed. Left-handed where we are right.
Looking back in a way that, somehow, we cannot quite see ourselves doing. Although, I suspect we do.
