how does light travel?

Big AI job. Grok 4.3 reads the canon and writes a Lean-grounded derivation; usually 20 seconds to 2 minutes. Your answer will appear below.
confidence: low outside recognition cached

The supplied Lean module derives specific gravitational lensing effects (deflection angles, Einstein radius, Shapiro delay) from the RS action principle and the Schwarzschild metric under the assumption that light follows null geodesics. It does not contain any theorem or derivation addressing the fundamental question of how light travels, its speed, or its propagation mechanism in flat space or within the broader RS framework.

outside recognition

Aspects Recognition does not yet address:

  • Fundamental mechanism of light propagation
  • Derivation of light speed (c = 1 voxel/tick)
  • Null geodesic principle as a base axiom or theorem
  • RS-native explanation of light travel independent of lensing
