Are Massive Structures Under Giza Pyramids Real? 2026 Science Explains Claims Summary

On March 15, a press conference in Italy sparked global headlines by claiming the existence of vast, non-natural structures deep beneath the Giza Plateau. The researchers, including Filippo Biondi and Corrado Malanga, asserted that their technology revealed a complex geometric environment extending nearly two kilometers underground. These structures reportedly consist of eight massive cylinders surrounded by constructs resembling spiral staircases, which merge into two giant cubic structures at a depth of over 600 meters. The scale of these alleged find is unprecedented, suggesting a level of engineering that would dwarf the pyramids themselves.

While the claims are breathtaking, the primary issue is the lack of a published technical paper for the 2025 findings. Current information relies heavily on press releases and the researchers' previous work from 2022. This lack of transparency makes it difficult for independent geophysicists to verify the data. The narrative presented suggests a subterranean world that defies our current understanding of ancient Egyptian capabilities, or perhaps even geological reality.

The methodology behind these claims is known as Synthetic Aperture Radar (SAR) Doppler Tomography. Typically, SAR is a standard tool used by satellites to track ground movements by pinging radar waves off the terrain and analyzing the return signal. However, radar waves at standard frequencies (around 10 GHz) are easily blocked by dense rock, making them generally unsuitable for 'seeing' through a pyramid. The researchers claim to have overcome this by measuring surface vibrations rather than direct penetration.

The theory is that internal structures affect the way the surface of the pyramid vibrates. By tracking the Doppler shift in radar frequencies caused by these micro-vibrations, the team believes they can reconstruct a 3D model of what lies beneath. This technique is conceptually similar to how geophysicists use seismic waves to map magma chambers under volcanoes. The crucial difference, however, lies in the frequency and the source of the vibrations being measured.
