The architectural precision of the Great Pyramid of Giza has long been a subject of scholarly interest, particularly concerning its structural integrity, geometric accuracy, and astronomical alignment. This study re-examines the pyramid’s construction through a comprehensive geometric and structural analysis, proposing a novel interpretation of its internal framework and mass distribution. By integrating trigonometric calculations and architectural evaluations, the research identifies the presence of a stabilizing rotated core within the pyramid, which may have contributed to its resilience against seismic forces and structural deterioration over millennia. A key finding of this study is the role of an internal clockwise spiral ramp, which facilitated construction and enabled precision in casing stone placement. This ramp, embedded within the pyramid’s mass, provided a structured means of ascending for construction workers, ensuring the accurate alignment of the pyramid’s four diagonals and apex. Furthermore, the study explores the relationship between the pyramid’s geometric proportions and its hypothesized astronomical correlations, drawing parallels between its spatial orientation and the celestial alignments documented in ancient Egyptian cosmology. The findings contribute to the ongoing discourse on ancient Egyptian engineering methods, shedding light on the pyramid’s enduring structural stability. By contextualizing the pyramid’s form within both engineering and astronomical paradigms, this research enhances our understanding of the architectural ingenuity of the Old Kingdom.
