Why this site. Giza is the most-claimed-about monument on Earth, and it deserves two separate answers. Our engine measures distances between monuments, and across the Memphite necropolis our October 2026 run returns 45 golden-ratio pairs where chance predicts 39.8 (p = 0.1799; our August run said 30.1), which sounds like something until the control lands: the control ratio pi/2 scored 1.23 times its expected count against phi's 1.13 and beat it. Separately, and this is the part most tests skip, the pyramid's own proportions really do approximate both pi and phi to within a twentieth of a per cent, because a slope of 5 and a half palms per cubit produces both at once. Flinders Petrie, who surveyed it, thought that was deliberate. Whether he was right is still open. We print the measurements and let you weigh it.
