Filippo Biondi

Rogan states the stakes before the guest has said anything substantive: this is the research behind the most controversial claim in the field, and if the data hold, "it essentially rewrites all of human history." Biondi accepts the framing without inflation. He begins not with the pyramids but with the composition of the group — Corrado Malanga, and a chemistry chair at Pisa.

if it's accurate, it essentially rewrites all of human history

The one thing the opening makes clear is that the claim will rest entirely on method. Biondi is not an archaeologist; he is a telecommunications engineer, and the interview treats that as the relevant credential rather than an absence.

I am a telecommunication engineering

His academic path is given in brief: a degree at Lecce, a university named for the mathematician Ennio de Giorgi — with an aside about de Giorgi and John Nash attacking the same Hilbert problem a week apart — then a doctorate at La Sapienza. Then the part that matters: years of work on radar and synthetic aperture radar, some of it for the Italian military, which he cannot discuss.

I worked on radar and synthetic battery radar for a lot of time

Rogan asks whether the classified work is where the technique came from, and Biondi describes the platform without mystique: a radar on a satellite, six hundred kilometres up, moving at seven kilometres a second, taking snapshots of the ground as it passes.

The satellite flies in the space at a distance of 600 kilometers at 7 km per second in velocity

The explanation of the method is the technical core of the episode and it is given in the register of a lecture. The raw snapshots must be focused in azimuth, and that focusing is done through the Doppler shift — the same effect that raises the pitch of an approaching sound.

when you hear noises that are approaching to you, this noise will rise the frequency

The claim that follows is the one everything else depends on: the same processing captures the mechanical vibration always present at the surface, and that vibration carries information about what lies beneath it. Note what is and is not being asserted — no signal is said to penetrate the ground; the ground is read at its surface.

this vibration, which is mechanical vibration, carries inside of this the information that is located underground

The origin is not a grand plan. Having developed the method, Biondi happened to know Malanga, who in 2018 was studying the pyramids and needed interior information to finish his own work. The offer was instrumental: use my technique. The first scans followed in 2019.

it was a coincidence that I knew Corrado Malanga

The project then split in two. Version one was trained narrowly on the Great Pyramid, watching only its interior; the results were published in a peer-reviewed paper in 2020. Only after that did the group widen the survey to the whole plateau.

we published a peer review paper

The strongest part of the case, as presented here, is that the method was first checked against structures whose dimensions are not in dispute. It resolved the internal multi-layer feature known as the Z, and it produced images of the Grand Gallery, the Queen's Chamber and the King's Chamber, correct in size, dimension, position and location.

And accurate in terms of size and dimension. And also position and location

Only then did the group turn to the ground beneath, on the suggestion of the third member, Armando Mei, and widen the scan to the entire plateau. Rogan asks for a date and the answer is cut off by an ad break rather than evaded.

Retuning the algorithms for depth produced the images that made the story travel: structures that read as enormous columns, on his estimate twenty metres across. His own first reaction was disbelief, and the group sat on the results for six months — "my opinion was that was not real" — suspecting noise or a processing artefact.

we had those results in our desk without disclosure anything for six months

Rogan asks whether the regularity was itself suspicious — uniform spacing, aligned placement. Biondi's answer is that regularity is what pushed him toward disclosure rather than away from it, because the check available to him was replication on different hardware.

diversity is a good thing because it confirms other things that we were searching

The replication claim is quantitative: Italian Cosmo-SkyMed satellites first, then American Capella Space and others, and more than two hundred scans over the area with consistent results. That consistency is the whole of the evidentiary argument as stated here, and it is worth being explicit that it is a claim about repeatability, not about independent verification by other groups.

How many different scans have been done on this area? Two or three hundred, more than 200

Rogan supplies the counter-explanation he finds most plausible: gatekeeping. He calls the resistance confirmation bias — a wish that the finding be false, held independently of the scan count — and Biondi does not argue the point, which leaves it as Rogan's diagnosis rather than a shared conclusion.

They want this to not be true, regardless of the sheer number of scans
