Great Pyramid 'code' claim sparks debate over ancient knowledge

Independent researcher Sefy Levy argues the Great Pyramid encodes a hidden numerical system tied to lunar cycles and celestial movements, suggesting the monument was designed to preserve advanced knowledge (math, astronomy) for eternity rather than merely commemorating Khufu. The theory hinges on parsing pyramid measurements with ancient Egyptian fractions and linking them to numbers like 27.5, 70, pi and phi; it was tested against 100,000 computer-model pyramids, with about 2.4% matching, but there is no peer‑reviewed evidence, and the idea sits among other pyramid conspiracy theories.
