A New Idea: Particles as Numbers on a Branching Tree
A plain-language version of “ODR Thesis: The Compton Count as the Only Primitive”
The short version
This paper says a particle is simply a counting number based on its mass. That number sits on a special branching tree. The paper brings together five fields that found the same tree but never talked to each other.
What is a particle?
People have asked "what is a particle?" for thousands of years. Today's physics gives several answers. One view says a particle is a ripple in an invisible field. Another view says some particles only exist inside materials and borrow their mass from the material around them. The new idea here is bolder: a particle IS its Compton count. This count is simply the particle's mass divided by the smallest possible mass, the Planck mass. The result is a plain fraction — a ratio of two whole numbers. This fraction is the particle's true identity.
How the count finds a place on a tree
Every fraction can be broken down into prime numbers. The list of prime building blocks gives the particle an exact spot on a mathematical object called the Bruhat–Tits tree. This tree is like a family tree that never ends. Each spot branches out in a set number of directions. The tree has no center point — every spot looks the same. The tree also has no built-in size — no meter stick lives inside it. Size and scale come only from how the branches connect. The paper calls this tree the natural home for particle identity, replacing the usual three-dimensional space we learn in school.
The number system of nature
For about four hundred years, physics has used the full number line with all its infinite decimals. This paper asks a different question. What if nature uses only fractions — ratios of whole numbers — as its basic numbers? The full number line with endless decimals would then be just one way to complete the fractions, not the true foundation. The paper says every completion of the fractions matters equally. A particle's mass is one completion. Its prime-based spots on the tree are other completions. None is more real than another. The paper calls this view "place-democracy."
What about numbers like pi?
A common objection asks about famous numbers like pi, the ratio of a circle's around to its across. These numbers are not fractions. The paper answers that pi is still a limit that fractions can approach step by step. In the right units, pi is simply a ratio of two measured lengths. It does not force us to accept the full infinite number line as basic.
Quasiparticles and their shifting identity
Some particles inside materials have an effective mass that changes when the material changes. The paper handles this by saying these quasiparticles are not fixed spots on the tree. Instead, they are calculated from the fixed spots of the bare particle and the material around it. This explains why physicists call some particles elementary and others emergent. The paper says this claim would fail if anyone ever found a quasiparticle with the same mass in two different materials. No such case has been found in about ninety years of searching.
Testable guesses
The paper lists five ways to test these ideas. Two stand out. First, light from far-off star explosions might arrive at slightly different times depending on the light's energy. This would happen because the tree structure changes how very fast particles travel. Existing telescopes could test this within a few years. Second, the quasiparticle test already described could be checked against past data now. Three other tests need more work before they become ready.
Five fields, one tree, no talking
Between 1916 and 2016, five separate fields found the same branching tree. Number theorists found it in 1916. Quantum physicists found a related idea in 1928. Computer scientists built it in 1960. Mathematical physicists named the Bruhat–Tits tree in the 1980s. Holography researchers used it starting in 2016. None of these groups connected their tree to the others. The longest gap lasted 110 years. The paper says this silence cost science dearly — physicists worked with the wrong number system for particles because nobody crossed these boundaries.
What the paper does not show
The paper is honest about its weak points. It does not prove that the usual rules of motion and symmetry emerge from the tree at everyday scales. It does not yet calculate the exact energy-shift for star-explosion light. It does not handle particles that push and pull on each other — only free particles are fully treated. The tree idea for space itself is called the most fragile claim. The paper marks these as guesses, not facts.

Numbers it reports
Such an observation has not been reported in approximately 90 years of condensed matter physics. [speculative; null test held for ~90yr]
from 2.3 The Quasiparticle ExtensionPhysicists have used $\mathbb{R}$ for approximately 400 years, implicitly treating the Archimedean completion as the "real" number system.
from 3.1 Ostrowski's TheoremSystematic review of PDG and solid-state databases would test this negative prediction — it has held for approximately 90 years since Landau's Fermi liquid theory.
from 5.3 P5: Quasiparticle Invariance Null TestA single counterexample (identical $m^*$ in two chemically distinct lattices) would disconfirm the claim. [speculative] Testability: P2 is testable within 2-5 years with existing Fermi-LAT data or the Cherenkov Telescope Array (CTA).
from 5.3 P5: Quasiparticle Invariance Null TestRQ4 candidate P2 (Lorentz-violation dispersion from tree discreteness, testable with Fermi-LAT GRB data within 2-5 years) is the fulcrum: if confirmed, it elevates RQ1-3 from Philosophy to Physics.

How it is done
Ostrowski's theorem (1916) proves that the only non-trivial absolute values on $\mathbb{Q}$ are the Archimedean absolute value (the usual real norm) and the $p$-adic absolute values for each prime $p$ [established — mathematics].
from 3.1 Ostrowski's TheoremThe thesis proposes that Lorentz invariance is an emergent Archimedean symmetry, recovered at large separation scales where the tree's discrete structure is smoothed into the real continuum. [speculative — no proof exists] The p-adic AdS/CFT program faces the same issue: the BT tree's isometry group is $\operatorname{PGL}(2, \mathbb{Q}_p)$, not the Poincaré group.
from 4.3 Lorentz InvarianceThe 110-year gap between Ostrowski's theorem (1916) and its application to particle ontology (2026) represents a century of physics done on $\mathbb{R}$ when the natural number system for particle identities was $\mathbb{Q}$ with its $p$-adic completions.

What would falsify it
This is not a flaw — it is the precise geometric account of why condensed matter physicists distinguish elementary from emergent excitations. [speculative] Falsifiability: RQ1 would be disconfirmed if a quasiparticle were found with an effective mass identical across multiple chemically distinct host lattices — a single counterexample would demonstrate context-independence in a rational function.
from 2.3 The Quasiparticle ExtensionThis precedent supports the claim that Lorentz breaking is UV-only and undetectable at accessible energies. [speculative] Falsifiability: RQ3 would be disconfirmed if Lorentz violation were detected at energies below the Planck scale AND shown to have no tree-geometry structure — i.e., if the symmetry breaking were smooth and continuous rather than prime-structured.
from 4.3 Lorentz InvarianceWithout at least one falsifiable prediction that distinguishes ODR from standard QFT, the thesis is Philosophy rather than Physics.
