A recent study has revealed that the Great Pyramid of Egypt is not simply a four-sided structure. Research published in 2023 in the journal Archaeological Discovery indicates that each face of the pyramid exhibits a slight concavity, transforming its traditional geometry into an octagonal figure, according to mathematician Akio Kato, the study’s author. This finding is based on satellite images and geometric analyses that identified features previously invisible from the ground.
Kato argues that this shape is not the result of a construction error, but rather an intentional decision that enhances the stability of the structure, allowing for a more efficient distribution of weight and absorption of stresses, such as those caused by seismic movements. Observations of the pyramid are not new; pilot P. Groves had already captured aerial images in 1926 showing indentations on the sides. Flinders Petrie also documented central lines on each face, reinforcing the theory that the ancient Egyptians possessed advanced engineering knowledge.
This discovery opens a new debate about the construction of the Pyramid of Khufu and how more than 2.3 million stone blocks were transported. As we reported in this note, the ramp theory has been questioned due to its logistical complexity.
