The Joe Rogan Experience.

Jamie (0:06)

Trained by day, Joe Rogan Podcast by night, all day.

Joe Rogan (0:12)

How are you, sir?

Filippo Biondi (0:13)

Fine, thank you.

Joe Rogan (0:14)

Thank you very much for being here. I'm really excited to talk to you. Obviously, there's been an amazing amount of interest and controversy because of your work. We should explain to everybody right off the bat what this is about. You are the man that was at the head of this research that is looking at structures that are underneath the bottom of the pyramid. And incredibly controversial, very fascinating. And if it's accurate, it essentially rewrites all of human history.

Filippo Biondi (0:46)

Yes. Thank you for this invitation. And yes, the group is composed by Corrado Malanga, which is the head of the group and the dean, a professor of chemistry at the University of Pisa.

Joe Rogan (1:02)

Can you explain your background, please, so people would understand?

Filippo Biondi (1:05)

Yes. My background is this. I am at Telecommunication Engineering. I graduate at the University of Pisa.

Joe Rogan (1:11)

What is that word again? Say it again.

Filippo Biondi (1:12)

Telecommunications Engineering.

Joe Rogan (1:13)

Telecommunications Engineering. Okay.

Your English is excellent, but your Italian accent, although fabulous, sometimes it's difficult to translate.

Filippo Biondi (1:22)

Thank you very much, Joe. I'm sorry, yes, that I'm not mother tongue of English.

Joe Rogan (1:27)

It's still much better than my Italian.

Filippo Biondi (1:29)

Okay. Thank you. Yes. I graduated myself at the University of Lecce, south of Italy, a very nice university, and it has the name of a famous mathematic Italian, which is Ennio de Giorgi. Ennio de Giorgi was living in the era when John Nash was living also, and they were one against the other, and they were both studying the 19 Hilbert problem, and Ennio de Giorgi solved this problem one week before John Nash.

Joe Rogan (2:20)

Ah, interesting. John Nash, who from the famous movie A Brilliant Mind, with Russell Crowe.

Filippo Biondi (2:26)

Yes. Yeah. So then I performed my PhD at La Sapienza in Rome, and now I'm here.

Joe Rogan (2:35)

And how did you get involved in this discovery?

Filippo Biondi (2:39)

Yes. I worked on radar and the synthetic aperture radar for a lot of time.

Joe Rogan (2:48)

For the Italian military, right? Some work.

Which you can't really talk about.

Filippo Biondi (2:53)

No. Right. And I was involved in some research where, together with the Italian Research Council of Bari, always south of Italy, we were testing some special processing that were able to perform something special. And so, this is...

Joe Rogan (3:22)

So, this top secret research that you work on for the Italian government led you to try this stuff out, try this technology out. And this is satellite-based technology, correct?

Filippo Biondi (3:34)

Yes.

Joe Rogan (3:34)

And it's radio tomography?

Filippo Biondi (3:37)

Yes. It is something, in my personal opinion, very simple.

The radar is installed on-board on the satellite. The satellite flies in this space at a distance of 600 kilometers, at 7 kilometers per second in velocity. So, while it flies along the orbit, it is able to catch snapshots of the Earth. The snapshots have to be focused. And this focusing procedure, let's say it in the azimuth, I take it easy, in the azimuth direction, is done by sound, by the processing of sound, because it is involved at the so-called Doppler frequency. You know, Joe, when you hear noises that are approaching to you, this noise will rise the frequency, because the target has a velocity, a positive velocity with respect to you. And so the frequency is raised up. And this procedure allows us to estimate, or to grab, let's say, the vibration information that is always present at the surface of the Earth, in terms of evanescent waves that are present on the surface of the Earth. So this vibration, which is mechanical vibration, carries inside of this the information that is located underground. And so, we did this.

Joe Rogan (5:13)

And was it a specific idea, was it the idea specifically to look under the pyramids, or was it something that was discovered accidentally?

Filippo Biondi (5:23)

Okay, yes. Once we discovered this method, it was a coincidence that I knew Corrado Malanga. And at that time, we are in 2018, he was studying the pyramids. And so, we were talking about something that, if there was some methods able to scan inside the pyramids, because he needed some information to conclude the research that he was doing. And so, I proposed him to use my technique. And we started to work together. And so, we focused at that time on the pyramids.
