An Italian scientist, part of the research group at the University of Pisa, left the scientific community in suspense after declaring that he had found one “Underground City” Under the Egyptian pyramids. The discovery is about spiral staircases.
Filippo Bondi developed the method that first revealed the structures and then said this in an American podcast 4 other companies confirmed their results with topographic data identical to yours.

Bondi developed the method based on Synthetic aperture radar (SAR, in English). Using the Earth’s natural microscopic vibrations, they managed to create one Three-dimensional reconstruction of the pyramid’s subsoil. This is how they discovered the eight hollow cylinders surrounded by a spiral under the Pyramid of Chephren, the second largest in the Giza complex, which led to a chamber measuring 500 cubic meters and almost 700 meters deep.
The team said it found similar structures under the pyramid of Mycerinus, the third largest, and a cylinder under the Sphinx, all with spirals around it, which the team believes were stairs. “The pyramids are the tip of the iceberg, they are just a hat to complete something that is buried. The substance lies at the bottom.”Filippo assured the podcast American alchemy.

Now Bondi and the rest of the team are waiting for permission from the Egyptian government to open the tunnels – which already lead naturally to the structures. buried under centuries-old rubble: They would be service entrances for the underground complex.
