The Great Pyramid of Khufu consists of about 2.3 million stone blocks averaging 2.5 tons, the heaviest over 50 tons. Its four sides align almost exactly with the cardinal directions, with an error of about 3/60 degree. In 2017, Nature published a muon imaging study revealing an unexplained large void above the King's Chamber. Mainstream scholarship explains it through state mobilization, ramps, and Nile canal transport. Fringe theories propose alien intervention, anti-gravity, or sonic levitation.

Debunked
Archaeologists have found workers' villages and ramp transport remains nearby, proving human organization built it. The astronomical alignment could be achieved by observation. "Ancient astronaut" and "lost high technology" theories are fringe hypotheses with no physical evidence. Mainstream archaeology holds that with mature quarrying, transport, and state organization, the construction was entirely feasible.
