Discussions regarding the construction and purpose of the Great Pyramid of Giza have transitioned from addressing extraterrestrial theories to exploring potential mathematical encoding.

Initially, Egyptologist Joyce Tyldesley addressed popular theories suggesting the monument was built by aliens, attributing the persistence of such ideas to 19th and 20th-century science fiction. She maintains that the structure is a product of ancient Egyptian geometry and surveying tools.

More recently, researcher Sefy Levy has proposed the ‘Pyramid as Memory Hypothesis’, suggesting the structure contains an intentional numerical system. Levy argues that the pyramid’s dimensions were designed to preserve knowledge of astronomical cycles and mathematical constants, describing the monument as ‘the knowledge…made stone’ through its alignment with lunar, planetary, and stellar intervals.

Levy’s research suggests that by applying fractions used by ancient Egyptian scribes to the pyramid’s measurements, one can uncover figures corresponding to astronomical events. Specifically, calculations reportedly align with the 27.55-day interval between lunar perigees and the approximately 70-day interval between Sirius risings. The hypothesis also links proportions within the structure to cycles involving Saturn, Jupiter, Venus, and Mars, as well as mathematical constants like pi and the golden ratio.

While these findings offer an alternative to the mainstream view of the pyramid as a funerary monument for Pharaoh Khufu, the study remains hypothetical. The numerical correlations have not undergone independent scientific peer review, and critics suggest such patterns may emerge after the fact once measurements and target values are known.
