“The Hidden Resonance Behind Early Cosmic Giants”
Resonance Function FR and Proper-Time Acceleration in RST
B.1 Substrate Field Equation
The substrate field S(x,t) obeys:
∂t2 S − c² ∇²S + β S³ = σ(x,t) (1)
- c — propagation speed of substrate waves
- β — cubic self-interaction coefficient
- σ(x,t) — source term representing emergent matter/energy
- S — scalar substrate field
This nonlinear wave equation supports soliton solutions (localized energy lumps) corresponding to emergent “matter.”
B.2 Background–Perturbation Decomposition
Assume a homogeneous background S̄(t) with small perturbations δS(x,t):
S(x,t) = S̄(t) + δS(x,t), |δS| ≪ |S̄|
Substitute into (1):
∂t2(S̄ + δS) − c² ∇²δS + β (S̄ + δS)³ = σ(x,t)
Expand the cubic term:
(S̄ + δS)³ = S̄³ + 3 S̄² δS + 3 S̄ (δS)² + (δS)³
Neglect (δS)² and (δS)³ for linear analysis:
∂t2 δS − c² ∇² δS + 3β S̄² δS ≈ σ − ∂t2 S̄ − β S̄³
Define the RHS as an effective driving term:
Fdrive(x,t) ≡ σ − ∂t2 S̄ − β S̄³
So the linearized perturbation equation is:
∂t2 δS − c² ∇² δS + 3β S̄² δS = Fdrive(x,t) (2)
B.3 Natural Resonance Frequency
For plane-wave perturbations:
δS(x,t) ∼ exp[i(k · x − ωt)]
Plug into the homogeneous part of (2):
−ω² + c² k² + 3β S̄² = 0
Thus the natural oscillation frequency is:
ω0(k) = √( c² k² + 3β S̄² )
This ω0 defines the substrate’s intrinsic resonance scale.
B.4 Definition of the Resonance Function FR
Define the resonance function as the overlap of local perturbations with the natural mode:
FR(x,t) = δS(x,t) · cos( ω0 t ) (3)
When δS oscillates in phase with ω0, FR is maximized. This measures how strongly a local perturbation resonates with the substrate, driving faster evolution.
B.5 Connection to Density Contrast Growth
In RST, the matter density contrast δ = δρ / ρ obeys:
δ¨ + 2H δ˙ − 4πG ρm δ = γ FR(x,t) (4)
- H — Hubble parameter
- ρm — average matter density
- γ — coupling constant linking substrate resonance to effective gravitational growth
The right-hand side is an additional driving term for structure formation, beyond standard gravity.
B.6 Proper-Time Acceleration
RST posits that local proper time responds to the substrate:
dτ = dt [ 1 + α FR(x,t) ]
α is a dimensionless scaling factor. Regions with high FR accumulate proper time faster, so matter evolves more quickly than in regions with low resonance.
In terms of proper time, the density contrast obeys:
d²δ / dτ² + 2H dδ / dτ − 4πG ρm δ = 0
Since dτ/dt > 1 where FR > 0, δ grows faster with respect to coordinate time t in resonant regions.
B.7 Early Galaxy Formation
Let δgal be the collapse threshold for galaxy formation. A resonant solution of (4) can be written schematically as:
δ(t) ∼ δ0 exp( ∫ γ FR(t') dt' )
In regions with strong resonance:
tgal,RST ≪ tgal,ΛCDM
Galaxies collapse earlier, and stellar populations appear more mature at redshifts z ≈ 10–12.
B.8 Summary: PDE to Early Galaxies
- Start: Substrate PDE ∂t2 S − c² ∇²S + β S³ = σ
- Linearize: Expand around S̄(t) → perturbation equation with driving term
- Resonance: Identify ω0, define FR = δS cos(ω0 t)
- Growth: Insert FR into δ¨ + 2H δ˙ − 4πG ρm δ = γ FR
- Time-rate: dτ = dt (1 + α FR) → accelerated local evolution
- Outcome: Faster growth → early galaxy formation without exotic dark matter

B.1 Step 1: RST Substrate PDE
The substrate field S(x,t) obeys:
∂t2 S − c² ∇²S + β S³ = σ(x,t) (1)
- c — propagation speed of substrate waves
- β — cubic self-interaction coefficient
- σ(x,t) — source term representing emergent matter/energy
- S — scalar substrate field
This is a nonlinear wave equation, capable of soliton solutions (localized lumps of energy) that can correspond to emergent “matter.”
B.2 Step 2: Background + Perturbation Decomposition
Assume the substrate has a homogeneous background S̄(t) and small perturbations δS(x,t):
S(x,t) = S̄(t) + δS(x,t), |δS| ≪ |S̄|
Plugging into (1):
∂t2(S̄ + δS) − c² ∇²δS + β (S̄ + δS)³ = σ(x,t)
Expand the cubic term:
(S̄ + δS)³ = S̄³ + 3 S̄² δS + 3 S̄ (δS)² + (δS)³
Neglect (δS)² and (δS)³ for a linearized resonance analysis:
∂t2 δS − c² ∇² δS + 3β S̄² δS ≈ σ − ∂t2 S̄ − β S̄³
Define the RHS as an effective driving term:
Fdrive(x,t) ≡ σ − ∂t2 S̄ − β S̄³
So the linearized perturbation equation is:
∂t2 δS − c² ∇² δS + 3β S̄² δS = Fdrive(x,t) (2)
B.3 Step 3: Natural Resonance Frequency
For plane-wave perturbations:
δS(x,t) ∼ exp[i(k · x − ωt)]
Plug into the homogeneous part of (2):
−ω² + c² k² + 3β S̄² = 0
⟹ ω0(k) = √( c² k² + 3β S̄² )
This gives the natural oscillation frequency of the substrate, ω0, which is crucial for resonance.
B.4 Step 4: Define the Resonance Function FR
Define resonance as the overlap of local perturbations with the natural mode:
FR(x,t) = δS(x,t) · cos( ω0 t ) (3)
When δS oscillates in phase with ω0, FR is maximized. This function measures how strongly a local perturbation resonates with the substrate, driving faster evolution.
B.5 Step 5: Connect FR to Density Contrast Growth
In RST, the matter density contrast δ = δρ / ρ is sourced by substrate perturbations:
δ¨ + 2H δ˙ − 4πG ρm δ = γ FR(x,t) (4)
- γ — coupling constant linking substrate resonance to effective gravitational growth
The RHS term is extra “driving” for structure formation, beyond standard gravity.
B.6 Step 6: Proper-Time Acceleration
RST posits that local proper time is affected by the substrate:
dτ = dt [ 1 + α FR(x,t) ]
α is a dimensionless scaling factor.
Regions with high FR experience faster local proper-time accumulation → matter evolves more quickly.
Then, the effective proper-time evolution of density contrast is:
d²δ / dτ² + 2H dδ / dτ − 4πG ρm δ = 0
Since dτ/dt > 1 where FR > 0, the density contrast grows faster than coordinate-time evolution would predict.
B.7 Step 7: Early Galaxy Formation
Choose a threshold δgal for galaxy collapse.
Solve (4) numerically or with a linear approximation:
δ(t) ∼ δ0 exp( ∫ γ FR(t') dt' ) (resonant growth dominates)
In regions with strong resonance FR:
tgal,RST ≪ tgal,ΛCDM
Galaxies collapse earlier. Stellar populations appear mature at z ≈ 10–12.
