The Great Pyramid of Khufu, or Pyramid of Cheops, was built over 4,500 years ago. The structure's height is 146.6 meters, and it consists of 2.3 million stone blocks weighing up to 60 tons. According to data, construction lasted 20–27 years, meaning roughly one block was installed per minute. The exact method of construction remains unknown to this day.
Professor Simon Schoiring proposed a new theory: instead of external ramps, the ancient Egyptians used internal corridors and chambers of the pyramid as a lifting mechanism with counterweights. In his view, this explains the pyramid's unusual design and shape. However, Egyptologists doubt the universality of this hypothesis, pointing out that neighboring pyramids, such as Khafre's, lack such internal spaces.
Russian researcher Roman Orekhov noted that the idea of an internal elevator raises questions, including the physical impossibility of using ancient ropes to lift multi-ton blocks. He also emphasized that the theory of a central shaft inside the pyramid remains speculation, as no evidence has been found to support it.
Nevertheless, Orekhov appreciated Schoiring's attempt to move away from the outdated theory of a giant inclined ramp, which has long raised doubts among specialists.
