The Pyramid Construction Enigma and the Limits of Scientific Knowledge

Abstract

This monograph undertakes a comprehensive multidisciplinary review of the unresolved question of how the Great Pyramid of Khufu was constructed, engaging critically with two centuries of Egyptological research and modern scientific investigations including muon tomography and the ScanPyramids discoveries. It systematically catalogues and evaluates all major extant construction theories—the external ramp, internal spiral, and Houdin's hybrid method—finding that none has achieved scientific consensus due to structural limitations of archaeological inference. The work develops in detail the cannibalization hypothesis, which proposes that the Giza plateau functioned as a closed-loop construction machine where successive pyramids recycled material from their predecessors, a model consistent with mass balance calculations and Egyptian recycling practices. The monograph then reframes the entire question epistemologically, examining how the loss of evidence, the problem of underdetermination, and cognitive pressures for closure, simplicity, and meaning drive both scholarly speculation and pseudoscientific proliferation. It argues that the persistence of this mystery is not a failure of effort but a structural feature of historical sciences, where product-to-process inference is inherently limited when construction infrastructure was intentionally dismantled. The principal findings confirm that no theory has been proven, the cannibalization hypothesis remains the most comprehensive current proposal, and the absence of evidence for ramps or internal spirals is as instructive as any positive discovery. Ultimately, this work offers not a definitive solution but a rigorous cartography of an unresolved problem, a methodological framework for continued investigation, and a sustained argument for intellectual humility as the central epistemic virtue in confronting one of the last great mysteries of the ancient world.
