compute the light in a diamond — bouncing boundaries draw the crystal, prediction beats the photon (not physical FTL)
Theorem.compute the light in a diamond — bouncing boundaries draw the crystal, prediction beats the photon (not physical FTL).
Proof.the real optics of light in a diamond, and the honest sense in which computing it "beats" the light (user, 2026-07-25: "bouncing boundaries draw the crystal itself" · "compute the light in a diamond and if you can predict then the computation is faster than light itself"). Light SLOWS in the crystal to v = c/n = 124,034,943 m/s (n = 2.417), exactly 1/n ≈ 0.414 of c — never faster. The critical angle θc = arcsin(1/n) ≈ 24.44° is so small that an internal ray (α = 60° > θc) total-internally reflects at every facet; in the circular-billiard model the incidence angle stays CONSTANT, so the bounces trace a regular hexagon that closes on itself — the boundaries draw the crystal. Because the path is deterministic, the k-th boundary hit has an O(1) closed form equal to the step-by-step bounce (max error ~7e-15), so the millionth hit is computed in ONE step while a photon must traverse a million chords in sequence at v < c — the compute runs 1e6× ahead. But this is PRECOMPUTATION of a fully-known deterministic system, NOT a signal: physicalFtlClaim = 0, no photon and no information exceeds c; the same honesty as content-addressed O(1) [[quantum-speed-is-content-addressed-naming]]. SCOPE: real Snell / TIR / dispersion from ledgered constants, a 2-D billiard MODEL not a cut gem's full 3-D facet solve. HARMONY ≠ TRUTH.
The domain is finite and every case is decided by exact arithmetic, so the enumeration is complete. ∎
