A recent non-peer-reviewed paper has revived alternative theories about the Great Pyramid of Egypt, proposing that the Pyramid of Khufu may have served as a cosmic communication device rather than simply a royal tomb. The theory points to the pyramid's highly precise alignment with the cardinal directions, its geographic position, and a striking numerical coincidence between its latitude (29.979234° N) and the speed of light (299,792,458 m/s). The author suggests the pyramid's placement and Earth's rotation could have subtly modulated gravitational patterns generated by Earth's orbit around the sun, potentially creating a kind of planetary beacon.
The paper also argues that the three pyramids at Giza were intentionally arranged to form a larger signal system, reflecting advanced ancient knowledge of astronomy and geometry. The claims remain highly speculative and have drawn criticism from archaeologists and physicists, who note that the theory depends on modern measurement systems unknown to the ancient Egyptians and lacks any scientific mechanism demonstrating that pyramids can transmit gravitational signals.
