Deep inside the Great Pyramid, engineer Christopher Dunn claims he found physical proof of advanced machining—marks that should not exist in a structure built with copper tools. Examining tight granite passages, he identified what he describes as precision drill grooves and saw cuts, evidence that challenges everything we believe about ancient Egypt.
Christopher Dunn has spent more than five decades working in precision manufacturing, building components for jet engines, satellite guidance systems, and surgical implants. In his field, a deviation the width of a human hair means a part is scrapped. He is not an archaeologist or historian. He is an engineer who understands what controlled cutting processes leave behind in hard materials.In 1986,…
