The Great Pyramid's conspicuous speed of light latitude is no accident

"The Great Pyramid was built ∼4500 years ago but a neighbouring monument exhibits considerably greater signs of ageing. Sea levels were appreciably lower at the end of the Ice Age when Giza was situated at the intersection of the lengthiest geodesic and parallel over land, a record the carving of the Sphinx appears to have commemorated. The Sphinx patiently weathered a hostile climate until the Great Pyramid was constructed, whose latitude in degrees tallies with the speed of light, c = 299, 792 km/s, to six significant digits. The pyramid's geometry showcases both π and the golden ratio, φ, with the conjunction π − φ^2 ≈ π/6 ≈ φ^2/5 not only providing a natural basis for the cubit/metre ratio but also approximating the speed-of-light latitude in radians. Its scaling reflects the size of the Earth and its rotation rate. By relating cubits to metres and days to seconds, this mighty monument quite deliberately encodes the value of c, figuratively permitting the conversion of energy to mass. Parallels exist with a recent analysis of Avebury, which also demonstrates ancient knowledge of modern physics."
