Now, though, one of these claims - which had been published in the peer-reviewed journal Remote Sensing - has since been retracted owing to "serious methodological flaws and statistical errors".

Originally published in 2022, the study, which was authored by Italian researchers Filippo Biondi and Corrado Malanga, concerned the alleged discovery of an "underground city" under the Great Pyramid of Giza.

The pair had used an imaging technique known as synthetic aperture radar Doppler tomography to build up a picture of what they believed to be hidden structures - including tunnels and chambers - inside the pyramid's walls.It wasn't long until the story had made headline news around the world.

The issue, however, was that no direct evidence of these alleged tunnels and chambers had been found and the pair's interpretation of the radar data was deemed to be highly questionable.

With no peer review and no forthcoming excavations to prove the existence of such features inside the Great Pyramid, the decision was ultimately made to retract the study.

"The findings and conclusions presented in this article are not reliable," the journal concluded.
