How Antigravity Built the Pyramids: The Mysterious Technology of Ancient Superstructures

Nick Redfern argues that acoustic levitation was the key to the construction of the pyramids of Egypt, Stonehenge, Easter Island, and Baalbek, Lebanon. He cites various stories and theories, including a 9th-century papyrus, a Mayan story of a humanoid overseeing the construction of the Pyramid of the Magician, and Native American stories of ancient priests making stones light to move easily. The truth of acoustic levitation remains a mystery, but it may have been the work of ancient humans or aliens.
