How the Universe Might Come from Information

A plain-language version of “Emergent Physical Reality”

The short version

This paper argues that space, time, and physical laws are not basic building blocks. They emerge from simpler rules about information. The author breaks down old ideas about physics. Then he rebuilds everything from three core rules about how information behaves.

The crisis in physics

Today's physics works well in practice. But its foundations rest on shaky ground. The two main theories do not fit together. One theory deals with gravity. The other deals with tiny particles and their forces. Scientists have hunted for smaller and smaller pieces of matter. This paper says that hunt misses the point. The very idea of "fundamental" parts is wrong. Instead, the physical world emerges from information processing. The paper tries to prove this with careful step-by-step reasoning.

Breaking down old foundations

The paper first shows that three famous numbers in physics are not truly basic. These numbers—gravity's strength, light speed, and the quantum constant—are just conversion tools. They vanish when equations use pure numbers without human units. The scale often seen as nature's smallest unit is built from these same non-basic numbers. So it too cannot be fundamental. This scale is called the Planck scale. Space and time geometry also fail as foundations. Geometry depends on matter. Matter depends on geometry. This circular trap means neither is basic. Both must emerge from something deeper.

Three rules to rebuild everything

The paper builds a new foundation from three starting rules, or postulates. The first defines what a physical system is: something with a state, which means information. This is a definition, not a testable claim. The second says information is conserved as systems change. This is the core physical guess. It could be proven wrong. The third is a rule of reasoning: when you lack full knowledge, assume maximum uncertainty. This is logic, not a law of nature.

Five levels of emergence

From these three rules, the paper derives physics step by step. Level one gets the study of large groups of particles and the study of heat and energy. This includes why disorder tends to increase. Disorder in a system is called entropy. Level two derives limits on how much information can fit in a region. It also shows why information scales with surface area rather than volume. Level three shows how ordinary space and time geometry emerge from information relationships on a boundary. This matches the holographic principle. That principle says all information in a space fits on its outer surface. Levels four and five sketch how gravity and particle physics could follow. Full details remain unfinished. The paper admits the exact math tool needed for level five is unknown. This tool is called the Hamiltonian. It is a math description of a system's total energy. It governs how the system changes.

What this does not show

The paper does not complete the full derivation of gravity or particle physics. It provides blueprints, not finished buildings. The specific operator that would reproduce all observed particles and forces has not been found. The author also does not prove that no other set of rules could produce similar results. The theory remains incomplete. Someone must find that unique operator. Then they must check it against every physical constant and ratio.

In the paper's words

This work presents a comprehensive, first-principles derivation of physical reality, positing that the universe is a hierarchical, emergent structure founded upon a minimal set of foundational postulates governing information, conservation, and logical inference. The argument proceeds in two stages: deconstruction and reconstruction. First, the traditional pillars of physics—dimensional constants, the Planck scale, and spacetime geometry—are critically analyzed and shown to be non-fundamental, derived concepts.

How it is done

Level 2 provides derivations of the Bekenstein Bound and Holographic Principle as arguments from physical consistency.
from Physical
Proof: Start with the standard form: $$i\hbar\frac{\partial \Psi}{\partial t} = -\frac{\hbar^2}{2m}\nabla^2 \Psi + V\Psi$$ Define dimensionless variables and operators: $t=t't_P$, $x=x'\ell_P$ (implying $\nabla^2 = \nabla'^2/\ell_P^2$), $m=m'm_P$, $V=V'E_P$.
from Time-Dependent Schrödinger
Proof: Start with the standard form: $$G_{\mu\nu} + \Lambda g_{\mu\nu} = \frac{8\pi G}{c^4} T_{\mu\nu}$$ Define dimensionless tensors by scaling with appropriate powers of Planck length $\ell_P$.
from Einstein Field Equations
This factor ensures consistency between the information density limit (Bekenstein bound) and the emergent geometric structure.
