Chapter 4: Ceilings and Information Erasure

The Hard Limit of Recursive Entropy and White-Noise Collapse


4.1 Overview

Entropy in ITT does not grow indefinitely. Unlike classical thermodynamics, ITT’s recursive substrate enforces a hard ceiling based on memory architecture.

When that boundary is reached, the substrate enters a white-noise state, erasing recursive memory.


4.2 The Entropy Ceiling

The maximum entropy a region can accumulate:

Sθ,max = nmax · ℓP² · Nfolds

Symbol Name Meaning
nmax Maximum recursion depth Permitted folds before saturation
P² Planck area Fundamental substrate resolution
Nfolds Fold sites Number of recursive locations

Physical interpretation: This is a computational saturation point beyond which no more meaningful structure can be stored.


4.3 The Saturation Ratio

Define the dimensionless saturation:

𝒮(n) = Sθ(n) / Sθ,max

Value State
𝒮 = 0 Zero entropy (perfect lock throughout)
𝒮 = 0.5 Half-saturated
𝒮 → 1 Approaching erasure threshold
𝒮 = 1 White-noise collapse

4.4 The Memory Collapse Transition

As Sθ → Sθ,max, the substrate undergoes a phase transition:

Stage What Happens
1. Memory degradation Tr(ℳ) → flat noise
2. Lock failure ℒ → undefined
3. Operator collapse Ψn+1 ≈ Ψn + noise
4. Entropic dominance σθ ≫ |dΦ/dn|

4.5 Behavior Near the Ceiling

As 𝒮(n) → 1:

Quantity Behavior
Shell-lock ℒ → 0
Time dilation γITT → 0
Entropy rate σθ → saturation
Memory trace Tr(ℳ) → flat noise
ITT temperature TITT → 0

Critical insight: Both time and temperature vanish at the ceiling—but for different reasons:

  • Time halts because γITT → 0
  • Temperature halts because the system can no longer exchange entropy

4.6 The Two Endpoints

Endpoint Condition State
White Noise 𝒮 → 1 before ℒ → 1 Information erased
Planck Lock ℒ → 1 before 𝒮 → 1 Information preserved

Black holes reach Planck Lock. Diffuse systems approach White Noise.


4.7 Implications

For Black Holes

Planck-core collapse is bounded at the entropy ceiling. No singularity forms because entropy cannot exceed the ceiling.

For Cosmology

Information on unreachable regions saturates and enters erasure. The cosmological horizon is an entropy boundary.

Information Paradox Resolution

Black holes don’t evaporate completely—they lock into Planck Cores at Sθ < Sθ,max.
