How Space and Time Might Come from a Static Network
A plain-language version of “Emergent Spacetime and Time from a Static p‑Adic Relational Graph”
The short version
This paper proposes that space and time are not basic building blocks of nature. Instead, they might emerge from a fixed network of connections. The authors use a special kind of math to define this network. They then derive several concrete predictions that could be tested against observations.
Why the old view causes trouble
Today's physics treats space and time as smooth and continuous. It also treats randomness in quantum mechanics as fundamental. This creates three hard problems. First, the energy of empty space cannot be calculated properly. Second, the rules for quantum measurement are assumed rather than explained. Third, computer simulations become too slow for large systems because they must track too many continuous variables.
The paper explores an alternative. What if the universe is a fixed, discrete network? In this view, empty-space energy would come from network shape. Quantum randomness would come from how observers move through the network. And calculations would become fast.
What the network looks like
The authors define a static network. "Static" means nothing changes in it from the outside. The network has points and links between them. Each link carries a weight. These weights use a special number system called p-adic numbers. This number system has a unusual property: the distance between two points is never more than the larger of their separate distances. This creates a tree-like space where all triangles are tall and thin.
The authors group nearby points into blocks. They define distance between blocks by adding up link weights. This new distance obeys the same unusual rule. Space thus emerges from coarse-graining, like seeing a smooth lake surface without noticing individual water molecules.
How time might emerge
The whole network stays fixed. But an observer inside the network, moving through a small part of it, would experience change. This experienced change is what we call time. It is not basic but comes from the observer's limited view.
What was calculated
The authors prove several results. First, a model of magnet-like behavior on a tree network shows a sudden phase change only when the prime number is three. This gives a way to identify which number system nature uses. Second, for one specific case, they calculate a light-cone shape length as twenty units. Third, they show that a bound on line directions in their space only restricts a special norm, not the ordinary count of lines. Fourth, they give exact formulas for how fast the network grows as one moves outward.
What remains unknown
The paper does not derive ordinary continuous space and time in full. It does not show that observers must experience the specific laws of physics we know. The phase transition result only works for one model on one tree shape. The light-cone calculation uses an assumed formula from prior work. The equiangular-line bound does not give a finite limit in ordinary counting. The coarse-graining error shows that very large distances are needed for high precision.
The authors note that connecting these results to real observations of entanglement patterns or cosmic background light remains future work. They have begun to make the idea testable, but they have not yet performed actual experiments or observations.

In the paper's words
The prevailing view that spacetime and quantum randomness are fundamental continuous entities conflicts with persistent conceptual and technical problems in quantum gravity and cosmology. A static, discrete, non‑Archimedean relational network offers a unified ontological alternative, but quantitative bridges to observable physics are missing. We define a p‑adic relational graph, derive an emergent ultrametric distance by coarse‑graining its adjacency structure, Using the p‑adic Potts model on a Cayley tree we prove that a phase transition occurs if and only if the prime p=3, providing a concrete signature of the underlying p‑adic substrate.

Application of the $p$‑adic equiangular‑line bound to a concrete $d=2$, $\gamma=0.5$ example; the bound constrains only the $p$‑adic norm $|n|_3\le1$ and yields no finite bound on the ordinary count of lines (Section 4).
from 1. IntroductionIn a $2$‑dimensional $p$‑adic Hilbert space with $\gamma=0.5$, the bound constrains only the $p$‑adic norm $|n|_3\le1$ and does not impose a finite upper limit on the ordinary number of lines.
from 5. ResultsSolving $\varepsilon(d,7)\le\eta$ for $d$ yields $$ \frac{14}{d-14}\le5\times10^{-3} \;\Longrightarrow\; d-14\ge\frac{14}{5\times10^{-3}}=2800 \;\Longrightarrow\; d\ge2814 . $$ Thus any pair of effective points separated by fewer than $2814$ graph edges would violate the $0.5\%$ error budget.
from 5. Coarse‑graining error bound for a target toleranceSubstituting $|d|_{p}=1$ (any $d$ not divisible by $p$) and $\gamma^{2}$ with $p$‑adic norm $1$ (e.g. $\gamma=0.5$ for $p=3$) reduces the bound to $|n|^{2}\le\max\{|n|,1\}$.
from Equiangular‑line bound under dimension and angle variationsA prototype ion‑trap system with $10$ qubits and full control electronics would require a cost estimate that depends on specific hardware choices; the performance metric will be determined by experimental measurement of ultrametric violation probability.
from (e) Projected cost and performanceThe concrete numerical results (phase transition at $p=3$, cylinder length $20$ for $p=5$, $k=2$, the bound constrains only the $p$‑adic norm $|n|_3\le1$ and does not impose a finite upper limit on the ordinary number of lines in $\mathbb{Q}_3^2$, and explicit vertex‑counting formulas) provide falsifiable predictions.

How it is done
We define a $p$‑adic relational graph, derive an emergent ultrametric distance by coarse‑graining its adjacency structure, Using the $p$‑adic Potts model on a Cayley tree we prove that a phase transition occurs if and only if the prime $p=3$, providing a concrete signature of the underlying $p$‑adic substrate.
from AbstractProof that a phase transition in the three‑state $p$‑adic Potts model on a Cayley tree occurs iff $p=3$ (Section 4).
from 1. IntroductionThis inequality links the number of admissible directions to the dimension $d$ and the common angle $\gamma$, mirroring the real‑space van Lint–Seidel bound. $p$‑adic quantum mechanics. $p$‑adic and adelic quantum mechanics extend ordinary quantum theory by allowing complex‑valued wave functions on $p$‑adic arguments $$3$$ .
from 2. Background and Related WorkGiven a partition $\mathcal{P}=\{B_\alpha\}$ of $V$ into disjoint blocks of size $m$, we define the effective distance between blocks $B_\alpha$ and $B_\beta$ as $$ d_{\alpha\beta}= \Bigl|\,\sum_{i\in B_\alpha}\sum_{j\in B_\beta} A_{ij}\,\Bigr|_p . $$ Using the $p$‑adic norm $|\cdot|_p$ from $$5$$ , $d_{\alpha\beta}$ satisfies the ultrametric inequality $$ d_{\alpha\gamma}\le\max\{d_{\alpha\beta},d_{\beta\gamma}\}, $$ ensuring that the coarse‑grained space is an ultrametric space.

What would falsify it
A single observation that would falsify the main claim is the absence of ultrametric clustering in high‑resolution entanglement data from a quantum simulator.
from 8.2 FalsifiabilitySpecifically, if the pairwise $p$‑adic distances inferred from measured correlations fail to satisfy the strong triangle inequality beyond statistical noise, the static $p$‑adic relational hypothesis would be refuted.
from 8.2 FalsifiabilityCan the $p$‑adic light‑cone structure be linked to observable causal horizons in cosmology?

from AbstractThis reliance incurs concrete costs: (i) the cosmological constant problem remains unsolved because vacuum energy is computed in a continuum field theory; (ii) the measurement problem persists because the Born rule is postulated rather than derived; (iii) numerical simulations of quantum many‑body systems scale exponentially with the assumed continuum degrees of freedom, limiting predictive power for large‑scale structure formation.
