As the debate over what lies beneath Egypt’s Giza pyramids becomes continues, the scientists at the center of the dispute have shared new details they believe will silence critics.

The row began when Italian researchers said they used radar pulses to map more than 4,000 feet below the Khafre Pyramid, finding enormous shafts, chambers and a possible ‘vast city.’

Independent experts claimed the technology could not reach such depths, deeming the findings as ‘unscientific’ and ‘outlandish.’

Filippo Biondi, who specializes in radar technology, told DailyMail.com: ‘Most [people are] convinced that we are using radar to scan below the earth [and] that is completely false.’

He explained they collected acoustics from deep in the ground, including seismic waves, noise from human activity and photon interactions, to map the newly found shafts and chambers that extend more than 2,000 feet below the surface.

Biondi said these waves were collected by radar, specifically by analyzing Doppler centroid abnormalities—shifts or distortions in frequency patterns used to detect underground structures or changes.

However, Professor Lawrence Conyers, a radar expert at the University of Denver, who specializes in archaeology and was not involved in the study, still raised doubts.

‘Photon interactions? This is science fiction. And frequency shifts of what? We now have three different energy sources moving around: radar (electromagnetic), sound (seismic) and light (photons). This is all gobbly-gook.’

As the war over what lies beneath Egypt’s Giza pyramids continues, the scientists at the center of the debate have shared new details they believe will quiet critics

Biondi, Mei and Corrado Malanga of Italy’s University of Pisa announced the discovery last month that took the world by storm.

While the team is positive their technology has uncovered what would turn Egyptian – and human – history on its head, if true, they have yet to publish the research in a scientific journal for independent expert review.

This has led much of the scientific community to question the validity of the images that captured massive structures deep in the ground.

Dr Zahi Hawass, Egypt’s former Minister of Antiquities, told The National: ‘The claim of using radar inside the pyramid is false, and the techniques employed are neither scientifically approved nor validated.’

However, Biondi and Mei spoke with DailyMail.com to clear up misconceptions surrounding their methods. 

Biondi said that by analyzing Doppler anomalies in the synthetic radar data, he and his team can extract acoustic information from the Earth, similar to how a microphone captures sound. 

‘With a historical record of the Earth’s acoustic data, we can apply a technique called tomographic inversion, which is based on the Fourier transform,’ he added.

‘This allows us to create detailed scans of subsurface structures.’

Researchers believe there are other structures reaching more than 4,000 feet below the surface. The scans captured structures extend along the northern side with a tuning fork shape

The images captured eight descending wells, each measuring between 33 and 39 feet in diameter and extending at least 2,130 feet below the surface.

The results also revealed staircase-like structures wrapping around each of the wells that connect to two massive rectangular enclosures in the middle.

Each chamber measured around 260 feet per side.

During a news briefing last week, the team also announced the discovery of a water system beneath the platform, with underground pathways leading even deeper into the Earth. 

They stated that unknown chamber-like structures below this system could be part of a hidden city.

Mei explained that the theory of the lost city is based on ancient Egyptian texts, specifically Chapter 149 of the Book of the Dead, which refers to the 14 residences of the city of the dead.

‘It describes certain chambers and some inhabitants of the city. That is why we believe it could be Amenti, as described in ancient texts,’ he said. 

‘Of course, we must be certain, but we believe this could be the case because the pyramids are located exactly where the texts say. 

‘The texts state that the pyramids were built on top of the city, sealing its entrance.’

Biondi also noted that the unknown chambers more than 4,000 feet below the pyramid could be related to the legendary Hall of Records.

The Hall of Records is a long-standing myth in Egyptian lore, believed to be a hidden chamber beneath the Great Pyramid or the Sphinx, containing vast amounts of lost wisdom and knowledge about ancient civilizations. 

However, there is no reliable evidence proving its existence.

The researchers hope to obtain permission from Egyptian authorities to excavate the Giza Plateau and validate their findings—potentially rewriting human history.

‘We have the right. Humanity has the right to know who we are because, right now, we don’t,’ Biondi said.

They believe the city was constructed by a pre-existing civilization 38,000 years old, which predates the oldest known man-made structure of its kind by tens of thousands of years.

Professor Conyers said: ‘That is a really outlandish idea.’

He added that at that time in human history people ‘were mostly living in caves’ 38,000 years ago.

‘People did not start living in what we now call cities until about 9,000 years ago,’ he said.

‘There were a few large villages before that but those only go back a few thousand years from that time.’

Professor Conyers, however, agreed a ‘well or tunnel’ may exist beneath the pyramids, having been there before the pyramids were built, because the site was ‘special to ancient people.’

He highlighted how ‘the Mayans and other peoples in ancient Mesoamerica often built pyramids on top of the entrances to caves or caverns that had ceremonial significance to them.’
