A 1940 aerial photograph of the Great Pyramid of Giza captured a shadow pattern that revealed the monument’s faces are not perfectly flat. Each of the four sides is slightly indented along its center line, producing an eight-sided structure. The detail is subtle and generally only visible under specific lighting conditions, which has kept it out of most popular accounts of the monument.
The photograph was taken by a Royal Air Force pilot near the spring equinox. At that time of year, the low sun casts shadows that highlight the concavity down the middle of each face. The indentation is estimated at roughly half a degree, and it is consistent across the pyramid. Because the feature is so faint, it is not visible from ground level under normal daylight.
The source of the story is a video essay that frames the pyramid’s construction as an unresolved mystery. The narrator describes spending three years investigating engineering and alignment data, and using a quantum computing experiment to test whether the standard explanation for the pyramid’s construction is physically plausible. The article below summarizes the factual and technical arguments presented in that video without reproducing its promotional or speculative tone.
The Great Pyramid is aligned to true north with an error of roughly three arc minutes. Survey measurements from the 1920s, conducted by engineer J.H. Cole, found that the four sides of the base differ in length by only a few centimeters over spans exceeding 230 meters. The entire footprint, covering about 13 acres, is leveled so that the variation in height between corners is around two centimeters. These measurements are published and have not been seriously disputed.
The standard account holds that the pyramid was built over about 20 years using a large workforce of paid laborers, copper tools, wooden sledges, and mud-brick ramps. Evidence for this includes the excavation of a workers’ village near Giza, which contained bakeries, breweries, and food preparation facilities. Graffiti found inside the pyramid includes gang names painted on stones. In 2013, a French team discovered papyri at the Red Sea port of Wadi al-Jarf, including a diary by an official named Merer that documents the transport of limestone blocks by boat to Giza. These records confirm that organized crews moved materials and that significant logistical planning was involved.
What the documents do not explain is the precision of the finished structure. The leveling of the base, the tight alignment to cardinal directions, and the narrow joints between massive stone blocks are all features that modern engineers consider difficult to achieve. Some casing stones are fitted with gaps of less than a millimeter. There is no surviving record describing the surveying or leveling methods that would have produced this outcome.
The video essay also discusses the difficulty of maintaining accuracy over a long construction sequence. Small errors at the base would normally compound by the top. The author of the video claims that a quantum processor, when given the known constraints of the project, produced a result suggesting the work could not have been completed in 20 years using the tools assumed in the standard account. This claim is presented as a thought experiment rather than a published scientific finding. No independent verification of this experiment is provided.
Another technical point concerns the lack of a bright pole star at the time the pyramid is believed to have been built. Because of axial precession, the star Polaris was not positioned at true north around 2500 BCE. The builders would have needed a method for determining true north using star observations or other means. Various theories have been proposed, including one published in the journal Nature in 2000 by Egyptologist Kate Spence, but none have been conclusively confirmed.
The concavity of the faces adds another layer of complexity. If intentional, it would have required cutting blocks at slightly different angles along each seam, which would increase the difficulty of maintaining tolerance. There is no consensus among researchers about whether the indentation was deliberate or the result of settling or construction methods. The video treats it as an intentional design feature, but this is an interpretation rather than a documented fact.
The video does not claim to know who built the pyramid. It argues that the standard explanation leaves unanswered questions about how the structure’s precision was achieved. The narrator states that he does not support alternative theories involving aliens or lost civilizations, but he also does not accept the conventional timeline as complete.
The video is produced by a creator who sells books and promotes a subscription community. The tone throughout is designed to generate curiosity and encourage viewers to seek further information from his paid material. His framing treats the pyramid as a near-mystical object, but the underlying measurements and historical records are real and have been discussed by Egyptologists and engineers for decades.
In summary, the 1940 photograph documents a genuine feature of the Great Pyramid that is rarely discussed in popular accounts. The monument’s alignment, leveling, and joint precision are all well-documented facts. The historical record confirms that a large organized workforce was involved. What remains unresolved is the exact set of methods that allowed the builders to achieve the observed accuracy. The video’s conclusion is that the official story is incomplete, but it offers no alternative explanation grounded in evidence. The rhetorical framing is speculative, and the central claim about the quantum experiment is not supported by any published research.
