Schofield’s Substrate Theory Vs Reactive Substrate Theory (RST)
Two Substrates, One Universe: Comparing RST with Schofield’s Substrate Theory.
Both Reactive Substrate Theory (RST) and Jim Schofield’s Substrate Theory share a bold premise: reality is not built on abstract math or empty space, but on a physical medium—a Substrate. But beyond that shared foundation, the two theories diverge sharply in how they define that medium, how it behaves, and what it means for matter, energy, and the cosmos.
Here’s a breakdown of where they align—and where they split.
What Is the Substrate?
Schofield’s Substrate is made of tiny, undetectable particles—mutually orbiting leptons. It’s a particulate medium, like a modernized aether. Energy moves through it like a “bucket-brigade,” passed from one lepton to the next.
RST’s Substrate is not made of particles at all. It’s a continuous, elastic field. It doesn’t carry energy—it is energy, stored as tension and geometry. Waves, forces, and matter are all just different patterns in this field.
What Is Matter?
In Schofield’s model, matter is built from arrangements of leptons. It’s a bottom-up structure: small pieces make bigger ones.
In RST, matter is a soliton—a stable knot of tension in the Substrate. It’s not made of smaller parts. It is the field, twisted into a dense, self-sustaining shape. Mass is just the energy stored in that tension.
How Do Forces Work?
Schofield’s forces rely on physical transfer—energy passed between leptons. This likely limits interactions to the speed of light or slower.
RST uses field geometry. Forces arise from gradients and distortions in the Substrate. The Substrate Field Equation:
(∂²S/∂t² − c²∇²S + βS³) = σ(x,t) · Fᴿ(C[Ψ])
describes how solitons (σ) interact with the field, how tension builds (βS³), and how feedback (Fᴿ) maintains coherence. This allows for non-local effects—like quantum entanglement or gravitational push—without delay.
Do We Need Cosmic Inflation?
Schofield’s model, being particulate and speed-limited, would likely require inflation to explain the uniformity of the universe. Distant regions couldn’t have equilibrated without faster-than-light expansion.
RST doesn’t need inflation. Because the Substrate is continuous and tension redistributes instantly, the universe achieves equilibrium from the start. The Horizon Problem dissolves into a geometric solution.
Summary
– Schofield’s Substrate: particulate, mechanical, speed-limited – RST’s Substrate: continuous, geometric, non-local – Schofield’s matter: built from leptons – RST’s matter: stable knots of field tension – Inflation: necessary in Schofield’s model, redundant in RST
Both theories aim to restore physical realism to physics—but RST does it by redefining the medium itself. It’s not just a return to materialism—it’s a leap into geometric monism.
Schofield’s Substrate Theory..
This special print edition of SHAPE has been produced to mark 10 years of the journal. Collated here are two issues, originally published in May and June 2019, which collect together key papers on Jim Schofield’s ground-breaking new theory of physics, the Universal Substrate. This is a completely new approach to sub-atomic physics that hypothesizes the existence of as as-yet undetectable heterogeneous material substance, filling all of known space.
"There is a fundamental flaw in Physics. Space is not empty. Substrate Theory can help tackle all the biggest questions in physics, from the Spacetime Continuum to the Uncertainty Principle, from Casimir Effect, Redshift, Time Crystals, Superfluids and Dark Matter, to Virtual Particles and the work of Frank Wilczek."

Unlike its distant cousin, James Clerk Maxwell’s Aether Theory, this new Substrate conception can explain all Quantum phenomena, the anomalies of the Double Slit experiments, Wave/Particle Duality and its own strange illusivity. Without wishing to sound hyperbolic, the ideas contained within these issues are nothing less than a revolution in science - a complete rethinking of contemporary physics from the ground up; commiting to the scrapheap of scientific progress much of the last century’s detour into a realm which we might call Quantum Ideality.
While both theories propose a foundational Substrate, Reactive Substrate Theory (RST) defines it as a continuous field of tension and geometry, whereas Schofield’s model treats it as a particulate medium of orbiting leptons—leading to fundamentally different mechanisms for matter, energy, and cosmic structure.
Here’s a clear comparison between Jim Schofield’s Substrate Theory (as outlined in his ResearchGate PDF) and the Reactive Substrate Theory (RST)
1. Nature of the Substrate
Schofield’s Substrate Theory describes the Substrate as a material substance made of tiny, undetectable particles—specifically orbiting leptons. Energy is transferred through this medium like a “bucket-brigade,” where each particle hands off energy to the next. This is conceptually similar to older aether models.
RST, by contrast, defines the Substrate as a continuous, elastic field—not made of particles, but of geometry and tension. Forces and energy are not handed off—they propagate as tension waves or non-local stress patterns through the field itself. This allows for instantaneous effects across space, such as gravitational push or quantum coherence.
2. Definition of Matter
In Schofield’s model, matter is built from arrangements of these underlying leptons. It’s a particulate view: matter is made of smaller pieces.
In RST, matter is not made of pieces—it is a configuration of the field. A particle like an electron or quark is a soliton: a stable knot of tension in the Substrate. Its mass is the stored energy of that tension. This geometric view allows RST to unify matter, energy, and space as expressions of the same field.
3. Mechanism of Force and Energy
Schofield’s theory relies on physical transfer between particles. This means energy propagation is likely limited by the speed of light, and long-range coherence (like entanglement or gravitational equilibrium) would require additional mechanisms.
RST uses field geometry. Forces arise from gradients, curls, and distortions in the Substrate. The equation:
(∂²S/∂t² − c²∇²S + βS³) = σ(x,t) · Fᴿ(C[Ψ]) shows how solitons (σ) interact with the field, how tension builds (βS³), and how feedback (Fᴿ) maintains coherence. This allows for non-local effects and rapid energy transfer without particle exchange.
4. Cosmic Inflation and the Horizon Problem
Schofield’s model, being particulate and speed-limited, would likely require Cosmic Inflation to explain the uniformity of the universe. Distant regions couldn’t have equilibrated without faster-than-light expansion.
RST bypasses this entirely. Because the Substrate is continuous and tension redistributes instantly, the universe achieves equilibrium from the start. No inflation needed. The Horizon Problem dissolves into a geometric solution.
– Schofield’s Substrate: particulate, mechanical, speed-limited
– RST’s Substrate: continuous, geometric, non-local
– Schofield’s matter: built from leptons
– RST’s matter: stable knots of field tension – Inflation: necessary in Schofield’s model, redundant in RST
Both theories aim to restore physical realism to physics—but RST does it by redefining the medium itself. It’s not just a return to materialism—it’s a leap into geometric monism.
