Epistemic Status: Exploratory theoretical Mathematical foundations are solid, physical interpretations are speculative but grounded in established theoretical approaches._

Overview This post proposes treating reality as an interconnected system of state machines, formalized through category theory. Building on Platonist views of mathematical primacy and recent developments in theoretical physics, I present a framework for understanding fundamental reality as logical/mathematical rather than purely physical.

Key Ideas

1. Mathematical Primacy Rather than viewing physical laws as fundamental, we consider them manifestations of deeper logical/mathematical structures. This aligns with:

• Platonic forms
• Mathematical universe hypothesis
• Computational approaches to physics
• Abstract structural realism

2. The State Machine Reality Framework (SMRF)

Core Components:

S: Set of possible reality states
T: Transition functions T: S → S
I: Initial states I ⊆ S
F: Validity functions F: S → {true, false}

Key Properties:

1. Determinism in transitions

2. Validity preservation

3. Mathematical continuity

4. Category Theoretic Formalization

Basic Structure:

• Category REAL with states as objects
• Transitions as morphisms
• Sequential composition representing time flow
• Identity morphisms for stable states

Advanced Features:

• Subcategories for reality branches
• Functors describing branch interactions
• Natural transformations preserving structure

Physical Interpretations

Conservative Interpretations

1. Time as morphism composition
2. Physical laws as transition constraints
3. Symmetries as natural isomorphisms

Speculative Extensions (Confidence: Lower, but mathematically consistent)

1. Quantum superposition as parallel states
2. Entanglement as functor-preserved correlations
3. Gravity as space-time functor transformation

Implications & Questions

Mathematical Questions

1. Can we derive known physical laws from this framework?
2. What are the completeness properties?
3. How does computational complexity manifest?

Philosophical Questions

1. What does this imply about the nature of time?
2. How does consciousness fit into this framework?
3. What are the implications for causality?

Technical Details (For those interested in the mathematical machinery)

For a reality branch B_i, we define:

B_i = (S_i, T_i, I_i, F_i) where:
S_i ⊆ S: Branch-specific state space
T_i ⊆ T: Branch-specific transitions
I_i ⊆ I: Branch-specific initial states
F_i: S_i → {true, false}: Branch validity

Natural transformations α: F → G must satisfy:

∀s,s' ∈ S, t: s → s'
α_s' ∘ F(t) = G(t) ∘ α_s

Discussion Questions

1. How does this framework compare to other mathematical approaches to fundamental physics?
2. What experimental predictions might differentiate this from standard physical theories?
3. How might this change our approach to unsolved physics problems?
4. What are the strongest objections to this framework?
