Reactive Substrate Theory (RST) – Dictionary for Humans
Reactive Substrate Theory (RST) – Dictionary for Humans
This is the “I’m smart but not formally trained” dictionary for RST. It’s written for curious humans who are okay with equations existing, but want the words to make sense first. Funny but technical, no condescension, no gatekeeping.
1. Full RST Dictionary (Plain English + Tech)
Field
Human version: Something that has a value everywhere. Like temperature in a room or wind on a map. RST version: S(x,t) and Ψ(x,t) are fields that fill space and can wiggle, bend, and store energy.
Substrate (S)
Human version: The “stuff” the universe is made of underneath everything. Not particles, not empty space, but a kind of reactive medium. RST version: S(x,t) is a nonlinear, tension‑bearing field. It stiffens when compressed and carries gravity as tension gradients.
Resonance (Ψ)
Human version: The pattern that rides on the Substrate. Think of a standing wave on a guitar string. RST version: Ψ(x,t) is the field that forms solitons (particles). It interacts with S and can become a stable lump.
Soliton
Human version: A wave that refuses to spread out. Like a stubborn water hump that just keeps going. RST version: A stable, localized solution of the S–Ψ equations. In RST, “particle” = soliton.
Coupling
Human version: When two things won’t mind their own business and keep affecting each other. RST version: Ψ deforms S (α|Ψ|²), and S focuses Ψ (κSΨ). That’s coupling.
Nonlinear
Human version: Push a little, it moves a little. Push a lot, it freaks out. RST version: Terms like βS³ and λ|Ψ|²Ψ make the response grow faster than the input. This is how you get solitons and avoid boring behavior.
β S³ (Stiffening Term)
Human version: The universe saying “Nope, you’re not allowed to collapse into infinity.” RST version: The βS³ term makes the Substrate push back harder the more it’s compressed, preventing singularities and runaway collapse.
ODE (Ordinary Differential Equation)
Human version: A rule for how something changes along one direction (like radius). RST version: The soliton shape equation for ψ(r) and S₀(r). It tells you how the particle’s profile changes as you move outward from the center.
PDE (Partial Differential Equation)
Human version: A rule for how something changes in more than one direction (space and time). RST version: The full S(x,t) and Ψ(x,t) equations are PDEs. They describe waves, interactions, and evolution.
Ansatz
Human version: A smart guess for the shape of a solution. RST version: Ψ(x,t) = ψ(r)e−iωt says: “Let’s assume the particle wiggles in time but keeps a fixed shape in space.”
Boundary Condition
Human version: Rules at the edges so the math doesn’t go feral. RST version: At r = 0: no slope. At r → ∞: fields go to zero. This makes the soliton finite and physical.
Gradient
Human version: Fancy word for slope or tilt. RST version: Gravity is a gradient of Substrate tension. Things roll “downhill” in S.
Energy Functional
Human version: A recipe that tells you how much “oomph” a configuration has. RST version: Integrate energy density over space → you get total energy. That’s the mass of the soliton.
Emergent
Human version: When something big and complicated shows up because lots of little things interact. RST version: Gravity, mass, and particles are emergent from S and Ψ, not fundamental objects.
2. RST Dictionary Cheat Sheet
FIELD = Something with a value everywhere (like temperature). SUBSTRATE = The underlying medium S(x,t). Carries tension and gravity. RESONANCE = The pattern Ψ(x,t) that can form particles (solitons). SOLITON = A stable lump of waves. In RST: a particle. COUPLING = S and Ψ affecting each other (feedback loop). NONLINEAR = Response grows faster than input (e.g., βS³, λ|Ψ|²Ψ). ODE = 1D change rule (shape vs radius). PDE = Multi‑direction change rule (space + time). ANSATZ = Smart guess for solution form. BOUNDARY = Rules at edges (center smooth, far away zero). GRADIENT = Slope. Gravity = slope in Substrate tension. ENERGY = Total “oomph” of a configuration. Mass = energy of soliton. EMERGENT = Big behavior from many small interactions.

4. RST Vocabulary for Beginners
This section is for future‑you, or anyone landing on your blog who thinks “this sounds cool but I don’t speak physics.” It’s the on‑ramp into RST language.
Core Ideas in One Breath
The universe is not made of tiny billiard balls. It’s made of fields. One field (the Substrate) is like a reactive medium. Another field (the Resonance) is like patterns in that medium. When the pattern and the medium balance each other just right, you get a stable lump: a particle.
Beginner Vocabulary
- Substrate: The “stuff under everything.” Not empty space, but a medium that can stretch, bend, and push back.
- Resonance: A pattern in the Substrate. Like a standing wave on a drum skin.
- Particle: A stable pattern (soliton) that doesn’t fall apart.
- Gravity: Not a mysterious force, but a tilt in the Substrate’s tension.
- Mass: How much energy is stored in the pattern.
- Nonlinear: The universe’s way of saying “things get weird when you push too hard.”
- Equation: A compact way of saying “if you do this here, that happens there.”
How to Read an Equation Without Panic
When you see something like:
∂²ₜ Ψ − v² ∇²Ψ + μΨ + λ|Ψ|²Ψ = κ S Ψ
You can translate it as:
- “Ψ wiggles in time” (∂²ₜ Ψ)
- “Ψ spreads in space” (∇²Ψ)
- “Ψ wants to oscillate” (μΨ)
- “Ψ pushes back on itself” (λ|Ψ|²Ψ)
- “S tells Ψ where to go” (κSΨ)
You don’t have to solve it. You just have to know what each piece is trying to do.
What You’re Allowed to Say (and Be Right)
- “Particles in RST are stable patterns in a medium.”
- “Gravity is tension in the Substrate, not a separate force.”
- “The equations describe how the medium and the patterns dance together.”
- “Nonlinearity is what lets particles exist without blowing up or fading away.”
That’s already more accurate than a lot of pop‑sci.
This “RST Dictionary for Humans” is meant to be a living page. As new terms show up in your journey — spin, topological charge, tensegrity, emergent spacetime — you can add them here in the same style: human first, technical second.
