DERIVING THE PLANCK LENGTH FROM THE LIGHT SECOND. A THOUGHT EXPERIMENT ON THE SPHINX AND THE GREAT PYRAMID.

The article presents a thought experiment linking the Planck length, a fundamental natural constant (~1.616255 × 10⁻³⁵ m), to the Light second (the distance light travels in one second, approximately 299,792,458 meters) through geometric and mathematical relationships involving the Great Pyramid of Giza and the Sphinx statue. By assigning an idealized base angle of about 51.84373° to the pyramid and using constants such as Euler's number and variants of the Golden ratio, the study derives proportions that connect cosmic distances—like the Earth-Moon distance—and ancient Egyptian measures, notably the royal cubit. The work suggests that these ancient monuments encode universal constants and cosmic proportions, implying a possible deep relationship between human creativity, sacred geometry, and fundamental aspects of space-time. Limitations include reliance on idealized values and the speculative nature of the intelligence behind these designs, with the author proposing further exploration of symmetries between material and spatial realities.
