Beneath Pyramid of Khafre, Giza
SAR Spiral Tube Structures — Function Unknown
Full Description
8 cylindrical tubes with spiral internal structures extending over 1km deep beneath Khafre's pyramid, detected by SAR Doppler Tomography (Malanga & Biondi 2022). Each tube contains a central core wrapped in helical formations. Geometric precision and regularity across all 8 tubes suggests intentional construction, not natural karst features. If artificial, these predate any known engineering capability by millennia. If natural, the mechanism that would create 8 perfectly regular spiral tubes in a ring pattern is unknown to modern geology. The 80-90m cubic chambers at the base defy comparison with any known ancient or modern underground construction.

The Golden Ratio (Phi) in Pyramid Geometry
The ratio of the Great Pyramid's slant height (apothem ≈ 186.42 m) to half its base (115.16 m) is 1.6188, within 0.05% of the golden ratio φ = 1.6180339887... The face angle of 51.84° is the exact angle produced by a triangle whose sides are in a φ relationship. This means the pyramid incorporates both π and φ simultaneously — a mathematical feat since π and φ are related through the equation: φ²...
Fibonacci Sequence in Pyramid Design
The Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144...) appears to be embedded in pyramid proportions. The ratio of consecutive Fibonacci numbers converges to φ (the golden ratio), which is encoded in the pyramid's face angle. The pyramid's base-to-height ratio of 11:7 can be approximated by consecutive Fibonacci numbers (e.g., 55:34 = 1.617...). The number of courses of stone...
Granite Machining Evidence
Christopher Dunn's engineering analysis of the granite sarcophagus in the King's Chamber reveals tool marks consistent with modern CNC (Computer Numerical Control) machining. The interior surfaces show a precision of 0.001 inches over large areas.

The Big Void: A 30-Meter Cavity Hidden Inside the Great Pyramid
In November 2017, the ScanPyramids project (a collaboration between Cairo University, Heritage Innovation Preservation institute, and international physics teams) announced the detection of a previously unknown void inside the Great Pyramid. Cosmic ray muons — high-energy particles that rain down from the atmosphere — pass through stone but are partially absorbed. By placing muon detectors inside...
SAR-Detected Megastructures: 8 Spiral Tubes and 2 Cubic Chambers 1km Below Giza
Italian researchers Professor Filippo Biondi and Professor Corrado Malanga used Synthetic Aperture Radar (SAR) Doppler Tomography to scan beneath the Giza pyramids, publishing initial results in Remote Sensing (October 2022, Vol. 14, Article 5231). The technique analyzes micro-movements generated by background seismic waves (phonon-photon interactions at the surface boundary), creating...
