This is not physics or philosophy proving that our ethic is true. Experts disagree about much of what follows, and relational quantum mechanics in particular is one interpretation among several, not settled consensus. What this is: a resonance — three fields, working independently at wildly different scales, keep arriving at the same shape of idea. That convergence is worth having in our back pocket. It is not evidence, and we will not present it as evidence.
Zine No. 9, The Lines We Drew, warns against precisely the move we must avoid here: dressing a human value up as a law of nature, the way the bell curve was recruited to make "normal" look like physics and eugenics followed. So we say it plainly, up front. The atoms do not owe us this conclusion. We are noticing a rhyme, not collecting a proof.
The claim, in one line
Sameness is the fragile or fabricated thing. Difference isn't a deviation from a baseline — it's the condition anything real, including a self, gets made from.
One clarification keeps that line honest, because it braids together two different mechanisms that happen to teach the same lesson. At the cosmic scale, sameness is fragile: near-uniformity was simply the early universe's default, and it was unstable — the smallest unevenness grew into everything. At the social scale, sameness is fabricated: the "typical profile," the flat baseline, is manufactured and then treated as ground truth. Two mechanisms. One moral. We should never blur them into a single tidy slogan, because the precision is where the argument holds.
Three scales, one shape
The early universe was almost perfectly uniform: the cosmic microwave background — the oldest light we can see, the Big Bang's afterglow — varies in temperature by only about one part in 100,000 across the whole sky. A truly uniform cosmos would have stayed a dead, featureless fog forever: nothing dense enough for gravity to gather, no stars, no us. Everything that exists, exists because that near-sameness broke. The tiny perturbations are not noise on top of the story; they are the story. This part is well established (Penzias & Wilson 1965; mapped by COBE, WMAP, and Planck).
Gilles Deleuze argued that Western thought habitually treats difference as secondary — judged by a thing's identity to a concept, its opposition to a contrast, its analogy to a standard, its resemblance to an ideal. All four smuggle in the same assumption: that a fixed baseline exists first, and difference is only the distance from it. Deleuze reverses it — identity is produced out of a prior field of difference, not the ground difference strays from (Deleuze 1994).
That is exactly what a diagnostic model does to Autistic people: it measures us against identity, opposition, analogy, and resemblance to a "typical" profile that was never the ground truth to begin with. The flat line is the construct. Difference is what's actually there. Damian Milton's work on the ontological status of autism (Milton 2012) makes a kindred point from inside autism studies — the neurodivergent "spiky profile" gets read as deviation from a flat, typical baseline that was never the ground truth.
At the opposite end of every scale, Carlo Rovelli's Relational Quantum Mechanics proposes that particles don't carry fixed, standalone properties — what a thing is only becomes determinate in relation to another system (Rovelli 1996). Reading Rovelli from the inside, Helen describes not being a fixed, bounded thing moving through the world but something that emerges in and through its relations and encounters (Edgar 2026). We flag this leg as the shakiest: it is interpretation, offered as rhyme, not as physics settling a question about people. (A related move we add here, not in Helen's essay: Karen Barad's agential realism holds that it is relationships, not pre-given separate objects, that come first — Barad 2007.)
One term we have to handle carefully
Deleuze's "smooth space" (Deleuze & Guattari 1987) does not mean uniform. It means a field of ungridded, intensive variation — the opposite of striated space, which is fixed, measured, gridded. So the CMB's uniform fog is not "smooth" in Deleuze's sense; it's a pre-individual field, prior to both. The useful move is not "the universe was smooth and that's good." It's that diagnostic categories are the striation — the grid laid over a field that was full of ungridded variation before the grid arrived — and what LYDTYSS protects (the spiky profile, ★stuff, no-wrong-configuration) is the ungridded variation the grid keeps trying, and failing, to fully capture.
The bridge: ethodiversity
Between the cosmic argument and the single nervous system sits a middle layer, and it keeps the whole thing from being merely personal or merely abstract. Ombre Tarragnat's ethodiversity — the variety of ways of being and behaving across humans and other animals — makes the same claim at the scale of behaviour, and locates it precisely: not inside one organism, but as a property of a relational field, the way biodiversity belongs to an ecosystem rather than any single species in it (Tarragnat 2025). Its opposite, ethonormativity — the unspoken grid of which ways of being are allowed to count — is functionally striation applied to behaviour: a grid laid over a field that was varied before the grid arrived. Stimpunks keeps this in the ethodiversity glossary; the term also has earlier roots in conservation biology (Cordero-Rivera 2017), which we note as a Stimpunks aside rather than part of Helen's essay.
So the chain runs: CMB perturbations, quantum relation, Deleuzian difference-before-identity (why difference is fundamental) → ethodiversity (the same claim, scaled to behaviour and species) → the spiky profile and LYDTYSS (the same claim again, scaled to one bodymind). Ethodiversity is what lets the cosmic-scale idea land as something ecological and communal, not only intimate. Zine No. 8, The Universe Runs on Difference, already carries this layer.
What it gives LYDTYSS — and how to use it
It doesn't make the phrase heavier. LYDTYSS should stay exactly as unadorned as it is; the page works because it stays intimate, not academic, and this material must never be folded into it. What it gives us is an answer, ready when someone asks why difference gets to be the starting point rather than a thing to explain or excuse: because that's the shape reality takes wherever we've actually looked, from the CMB to a nervous system. Not despite the mess — because of it.
Hold this as backing material: something to draw on if a funder, researcher, or skeptical parent asks us to justify the framing. Physics and philosophy have been implicit in the zines already; if this becomes a future zine, its distinct claim must stay clear of No. 8. No. 8's point is one of breadth — variety beats monoculture. This page's point is deeper and different: difference is ontologically prior — identity is produced out of a field of difference, not the baseline it deviates from. "Difference comes first," not merely "difference is good." Framed that way, it's a genuine addition, and the ontological floor under both No. 8 and No. 9. If it becomes a zine, it should keep Helen's first-person voice and byline — the essay's intimacy is the point, and flattening it into institutional "we" would lose exactly what makes it land.

The cosmic microwave background is the oldest light we can observe — the Big Bang's afterglow. For about 380,000 years the universe was too hot and dense for light to travel freely; once it cooled enough for atoms to form, light was released to travel in straight lines, and it has been arriving ever since as faint microwave radiation from every direction. Two things matter here: it is extremely uniform (about one part in 100,000), and the tiny variations that do exist are everything — gravity grew them into galaxies, stars, and us.
