# FAQ — General Relativity  
### TriadicFrameworks /docs/theories/general_relativity/faq.md

This FAQ answers common questions about General Relativity as a
**geometric coherence theory of gravity**.

Gravity = **coherent curvature**.  
Geodesics = **coherence trajectories**.  
Spacetime = **a geometric operator field**.

No force metaphors.  
No rubber‑sheet analogies.  
No Newtonian fallback.  
Zero drift.

## ❓ What is gravity in this module?

Gravity is **coherent curvature**.

Not:

- a force  
- an attraction  
- a pull  
- a rubber‑sheet depression  

Curvature is a **geometric operator field** that shapes coherence
trajectories (geodesics).

---

## ❓ What is spacetime?

Spacetime is a **geometric operator field** defined by:

- a stable metric  
- curvature operators  
- causal structure  
- regime‑aware geometry  

It is not a “fabric” or a visual surface.

---

## ❓ What is a geodesic?

A **geodesic is a coherence‑preserving trajectory**.

It is not:

- a path an object “wants” to follow  
- a force‑driven curve  
- a Newtonian orbit with corrections  

Geodesics arise from the **metric and curvature**, not from forces.

---

## ❓ What does stress‑energy do?

Stress‑energy is a **curvature‑source operator**.

It:

- deforms curvature  
- modifies geodesic structure  
- preserves geometric coherence when valid  

It does **not** “pull” or “attract.”

---

## ❓ Why avoid rubber‑sheet analogies?

Rubber‑sheet metaphors introduce:

- force drift  
- visual distortion  
- dimensional collapse  
- Newtonian fallback  

They misrepresent curvature as a **2D surface deformation**, which is
incorrect.

GR uses **tensorial curvature**, not visual metaphors.

## ❓ What are the RTT regimes for GR?

- **R0:** pre‑geometric (no metric, no curvature)  
- **R1:** stable metric  
- **R2:** curvature operators active  
- **R3:** dimensional curvature operators  

Regimes describe how geometry behaves as structure increases.

---

## ❓ What causes geometric collapse?

Collapse occurs when geometry fails structurally:

- **G1:** metric degeneracy  
- **G2:** curvature divergence  
- **G3:** geodesic incoherence  
- **G4:** causal structure failure  

Collapse is geometric, not probabilistic.

## ❓ How do I “run” this module as a student?

Use the operators:

- **𝓖** — metric  
- **𝓡** — curvature  
- **𝓣** — stress‑energy  
- **𝓓𝓮𝓯** — geometric deformation  
- **𝓖𝓮𝓸** — geodesics  
- **𝓒** — coherence  
- **𝓐** — adjacency  
- **𝓢** — causal structure  
- **𝓡𝓮𝓰** — regime transitions  
- **𝓒𝓁** — collapse modes  

Build geometry → compute curvature → evolve geodesics → evaluate
coherence.

---

## ❓ How does GR connect to other modules?

- **LDS:** dimensional profiles of geometry  
- **NoS:** geometric similarity and curvature overlap  
- **Information Theory:** causal distinctions  
- **FFT:** dimensional curvature operators  
- **Thermodynamics:** horizon regimes  
- **QFT:** fields on curved backgrounds  

GR is a **central geometric module**.

---

## ❓ Is GR a force theory?

No.

Gravity is **coherent curvature**, not a force.

Force language is drift and is not allowed in this module.

---

## ❓ Is spacetime “bent” by mass?

No.

Mass‑energy **deforms curvature** through the stress‑energy operator.  
No bending, stretching, or visual metaphors.
