Petrosyan, Petros M.: - The author, Petros Petrosyan, graduated from the Yerevan Engineering University of Armenia, as a nuclear engineer. However, his research on the pyramids began since 1988, after which he established a hypothetically assumed model of the cipher of the pyramid consisting of 14 levels and 365 small pyramids. The pyramids started to interest the author when he heard and read about the pyramids of ancient Egypt. Meanwhile, his interest in research began when he often heard arguments that the pyramids represent more than structures or sepulchers.
