For decades, the joke was that the pyramids were just the tip of the iceberg. And now, in 2025, groundbreaking scans have revealed something astonishing beneath the Pyramid of Khafre: five multi-level structures, eight deep cylindrical shafts stretching 648 meters, and two gigantic cubic chambers stretching 2 kilometers beneath the Giza Plateau. This discovery, made by researchers from the University of Pisa and the University of Strathclyde using advanced Synthetic Aperture Radar (SAR) tomography, is rewriting everything we thought we knew about the pyramids. Some theories suggest that these underground structures could be the remnants of an ancient, advanced civilization, or even part of a lost energy grid, echoing Nikola Tesla’s speculations that the pyramids were an ancient natural energy harvesting system. Could this discovery be proof that the Great Pyramids were not just tombs, but something much more sophisticated? And if so, what else could be hidden beneath the sands of Egypt?
