Conversion of 648 Metres to Feet: Key SAR Scan Discoveries Under the Pyramids of Giza Explained

Groundbreaking Discoveries Beneath the Giza Pyramids

Recent investigations have revealed astonishing underground formations located underneath the Pyramids of Giza. Scientists Corrado Malanga from the University of Pisa and Filippo Biondi from the University of Strathclyde, Glasgow, shared their groundbreaking findings during a press event held in Italy on March 15, 2025.

The researchers utilized Synthetic Aperture Radar (SAR) doppler tomography, a sophisticated radar technology, to analyze the Khafre Pyramid, which ranks as the second-largest edifice on the Giza plateau. Their initial research was published in the journals Remote Sensing and arXiv back in 2022, shedding light on these startling revelations.

Complex Subterranean Network Revealed

The analysis indicated an extensive underground network of structures that stretches nearly two kilometers (approximately 6,562 feet) beneath the pyramids. Among these findings were massive cylindrical formations that extend down to 648 meters (around 2,126 feet), merging into two large cubical structures.

During their presentation, Malanga and Biondi discussed their method for reconstructing the internal architecture of the Khafre Pyramid based on the SAR scans. They employed an innovative software program created by Biondi, which interprets radar signals as sound-like vibrations, effectively visualizing the pyramid’s hidden configurations.

According to their findings, five symmetrical structures were discovered at the pyramid’s base, each comprising five levels and featuring sloped roofs, interconnected by geometric pathways. Below this layer, they identified eight vertical cylindrical wells, approximately 648 meters deep, which appeared hollow and were encircled by spiral passages.

These wells connect to two sizeable cuboid structures estimated to measure around eighty meters (approximately 262.5 feet). The entire network is believed to extend about two kilometers beneath the pyramid’s surface, encompassing all three Giza pyramids.

“These aren’t natural formations,”Malanga asserted during the press conference.

Challenging Conventional Perspectives

While the precise purpose of these underground formations remains uncertain, Malanga suggested that the Giza pyramid complex could encompass more than merely serving as burial sites for the pharaohs. Traditionally, Egyptologists have posited that the pyramids were constructed around 2500 B.C. as final resting places for Khufu, Khafre, and Menkaure, relying on ramps and simple machines for construction. This new evidence casts doubt on long-held theories.

Interestingly, several theorists, including Nikola Tesla and Christopher Dunn, have previously suggested that the pyramids may have served as energy conduits. In his book, The Giza Power Plant, Dunn posited that these structures functioned as machines capable of converting vibrations into energy.

Elevating the discourse on pyramid functionalities, a recent excavation uncovered skeletal remains in a Sudanese pyramid, indicating that the pyramid building legacy extended beyond the elite classes, contesting the stereotype that they were exclusively burial sites for the wealthy.

As part of their initiative, the Khafre Project team is eager to pursue excavation opportunities to further investigate their findings, although this endeavor hinges on obtaining the necessary approvals.

As of this update, no additional information has surfaced regarding further developments in this intriguing discovery.
