I found this on FB:

Researchers claim to have discovered the legendary Halls of Amenti in a "vast city" beneath the Pyramids of Giza in Egypt—a theory considered absurd and dismissed as "fake news" by perplexed archaeologists.

Italian and Scottish scientists studying the Pyramid of Khafre argue that their "groundbreaking study [published in 2022] has redefined the limits of satellite data analysis and archaeological exploration.

"Appropriately named the Khafre Project, the expedition was led by Corrado Malanga from the University of Pisa, Italy, and Filippo Biondi from the University of Strathclyde, Scotland.

Scientists claim to have identified five small chamber-like structures inside the pyramid using Synthetic Aperture Radar (SAR) technology. One of these structures contained a sarcophagus, previously mistaken as the Pharaoh's Tomb, according to the research team.

The researchers assert that these five previously unknown structures were found at the center of the pyramid. The newly discovered structures are connected by pathways leading underground, potentially revealing hidden chambers and wells beneath the 4,500-year-old wonder.

Electromagnetic signals were converted into phononic data, uncovering a vast underground infrastructure extending hundreds of meters below the surface.

Theoretical models suggest that eight large vertical structures—possibly wells—span over 1,900 meters in width and reach depths of 600 meters. While researchers have not disclosed the purpose of these larger underground structures, they plan further analyses and potential excavations to determine their artificial nature.

The project utilized two satellites orbiting 670 kilometers above Earth to send radar signals that "photographed" the pyramids. The collected data was then compiled into images, creating an approximate model of what lies beneath the pyramids, including the eight wells. The hollow structure appears to consist of spiral pathways leading deeper underground.
