Their construction combines colossal scale with a degree of geometric precision that remains challenging to replicate even with modern technology. Prevailing construction theories-chiefly external or internal ramp configurations-exhibit logistical, material, and geometric shortcomings that struggle to account for the verifiable accuracy of the finished structures [1]-[3]. This paper introduces the String Line and Center Pole hypothesis as a unified and parsimonious model for Old Kingdom pyramid construction. It posits that a central, vertically extensible timber pole, erected at the geometric center of the pyramid's base, served as a stable datum. A measured string line, extending from this pole to the structure's ascending perimeter, functioned as an analog guidance system for maintaining the precise angle of incline and the uniform convergence of the four faces. The hypothesis is substantiated through a synthesis of architectural, technological, and symbolic evidence: (i) axial placement of primary chambers in Sneferu's Red Pyramid and the Giza pyramids [3], [6], [8]; (ii) technological plausibility of a large composite pole given Old Kingdom cedar imports and advanced joinery evidenced by the Khufu ship [12]; and (iii) cultural resonance with the Djed pillar, emblem of stability and the backbone of Osiris [11]. The framework is testable via targeted non-invasive scanning of the central axes, building on the demonstrated capabilities of the ScanPyramids mission [9], [10]. ...
