Project Phi Grid — Archaeological Extension v1.1: Monte Carlo test of dual-anchor φ-ratio grid node association with UNESCO World Heritage Sites and sensitivity analysis

A groundbreaking analysis identifies six statistically significant associations between UNESCO World Heritage Sites and a dual-anchor grid system, with one of the strongest signals (p = 0.0056) observed at a 200 km threshold. The study, an extension of Project Phi Grid, applies a Monte Carlo test to 87 cultural and archaeological sites using two anchor points: Wilkes Land (Antarctica) and the Hiawatha impact crater (Greenland). Sensitivity analysis reveals consistent results between 100–300 km, peaking at 150 km (p = 0.0001), while land-only nodes further confirm the signal with p = 0.0018. Notably, Göbekli Tepe exhibits a triple alignment against both anchors, marking it as 'HIGH INTEREST,' and Arslantepe Mound is confirmed as an additional hit at 125.6 km from Wilkes P13 n+1. All parameters were pre-specified to ensure robustness.
