Filippo Biondi, and Corrado Malanga have produced a text showing their unpatented Synthetic Aperture Radar technique works (Biondi, F.; Malanga, C. Synthetic Aperture Radar Doppler Tomography Reveals Details of Undiscovered High-Resolution Internal Structure of the Great Pyramid of Giza. Remote Sens. 2022, 14, 5231. https://doi.org/10.3390/ rs14205231)
This text describes "an imaging method based on the analysis of micro-movements on the Khnum-Khufu Pyramid", which they claim has achieved high-resolution full three-dimensional tomographic imaging of the pyramid’s interior and subsurface by processing series of SAR images from the second-generation Italian COSMO-SkyMed satellite system. According to them, the pyramid "becomes transparent when observed in the micro-movement domain". Based on their interpretations, they claim to have "completely reconstructed internal objects, observing and measuring structures that have never been discovered before". "The technique proposed in this article, unlike the classical SAR tomography developed in [52,64,65], has penetration properties orders of magnitude greater because what is proposed uses the vibrations (the phonons) and not the photonic information". The Pyramid they depict is full of voids, corridors and chambers. It also involved excavating huge masses of bedrock and dumping the rubble somewhere as yet undetected.
But what was it all for? Here's what they say about the functioning of this structure on pp 39-40/44 Note, this text was accepted by the journal's Academic Editors [Rosa Lasaponara, Ilaria Catapano, Luca Piroddi, Sebastiano D’Amico, Marilena Cozzolino, Nasser Abu Zeid, Patrizia Capizzi and Sergio Vincenzo Calcina].
The original is written as one massive-long paragraph, here split for clarity. In-text hyperlinks are my additions, the references to corridors and rooms arre toi both the existing nomenclature and their own ideas of where undiscovered ones exist]:
On the side of the Great Pyramid towards the river, the base is (acc. to Google Earth) 59 m a.s.l. The Nile is some distance aqway today., but the water level at the Cairo Kayak club in Giza is 16 m a.s.l. and the islands nearby have a height 16, 17, 18 m a.s.l. Yet the Italians claim [and this journal's academic editors accepted without challenge] that it once flowed at about +79 m a.s.l. (!). This is completre nonsense, it would have flooded sites on islands in the lower Nile valley (including Memphis) and ALL of the pyramid fields and their associated mastaba tombs (Hawara, Kahun, Meidum, Dashur, Zawiyet, Sakkara, Abusir etc). Completely stupid and utterly unfounded (and indefensible) idea. As for the nonsense about "boats" (eh?) and attendants clinging to the side of the pyramid (whatever its slope) using fragile early-dynastic siltstone vessels to lift Nile water up 90m to pour it down some shafts... it does make one wonder...."In the case of the pyramid of Khnum-Khufu, which we have analyzed in depth, it can be assumed, in analogy with other authors [5,25,76], that it was surrounded by an enormous basin full of water, which allowed the circulation of some boats. These boats were used by some attendants with the task of bringing the water to about 90 m high, pouring it into the south shaft by using many rotating stones probably similar to the Sabu diorite stone [28].
The SAR tec[h]nique allows us to provide evidence that the shape of this monument does not resemble a perfect pyramidic form because of the presence of a double changing in slope: the first of which is 14.5 ca. degrees at approximately 20 m high, while the second one is 6 degrees ca. at approximately 100 m high. The Nile River’s water should have filled the basin up to the height of the first change of slope of the pyramid, thus allowing the Egyptian boats not to get stuck with the keel on the side of the pyramid itself. "
Anyway this farrago goes on:
"The water would have invaded the King’s chamber, but having reached the height of the granite basin inside the chamber (often referred to as the sarcophagus), it would not have exceeded that level in height and would have instead risen in the north shaft, whose entrance is placed at the same height as the basin, creating an air seal that effectively airlocked the room. Having the King’s chamber in fact hermetically sealed would have caused excess water to rise up the north shaft.
The Queen’s chamber would also be filled with water, up to the height of the shafts, by means of two connections to the shafts of the King’s chamber, which were probably located in rooms 19 and 11, building a closed circuit, which is called Quincke’s tube [26].
As also proposed by other authors [77], the pyramid, with its megalithic structure, was placed in vibration by the wind and the low frequencies thus developed, which acted as a low-pass filter allowing only low frequencies to bounce back on the roof of the Zed toward the King’s chamber [16].Such a room would behave like an air-filled bottle of Helmholtz [29], in which the granite basin acted as a bottleneck. The walls of the basin, vibrating at low and precise frequencies, linked to the internal and external measurements of the basin itself, proportional to multiples of π and the Golden Ratio φ [16], would have caused the water contained in the Quincke’s circuit to vibrate. These frequencies, traveling through the closed circuit of Quincke’s tube, at about 1400 m/s (speed of sound in the water), reached the Queen’s chamber, where the height of the water could not exceed the height of shafts from the floor. A particular frequency could be developed, which was suitably amplified by the correct dimensions of the niche present in the west wall, which acted as a sound box for a musical instrument, releasing into the air a sound frequency that was able to interact with a cylindrical container placed on the floor of the room, the traces of which are still visible [14]. This cylindrical container, probably made of wood, was put into resonance by the obtained low frequency.
Two individuals were placed both in the basin of the King’s chamber and in the cylindrical container, in the Queen’s chamber and appropriately treated with this low sound frequency for curative and religious purposes [21]."
So the Pyramid is a healing machine? Healing by wind-driven vibrations (!). I suspect that if this were the case, siting it in a massive cemetery, surrounded by graves and other memento mori might not have been the best marketing decision. The same goes for all the other 4th dynasty pyramidal-vibro-spas.
Quite apart from proving being in a vibro-bath actually is a medicinal technique applied by ancient Egyptians (or anybody outside today's wellness-industry alongside healing crystals), the "brilliant" Italians seem not to have considered how those "individuals" would get INTO (or out of) both chambers if the entrances (and by implication the entire Grand Gallery) were filled with water. Duh. Such scientific rigour.
Heedless of such practicalities they blunder on:
"At the end of the procedure, the King’s chamber was emptied by letting the water out of the Great Gallery and conveying it toward the room called “Grotto” toward the “Unfinished” chamber which brought the water back through a path in the floor, now occluded by debris, to the Nile.
How to get in if the whole lot is filled with water?
Subsequently, the Queen’s chamber was emptied in two steps: first, a granite “plug” in the corridor leading to the room was removed: (this passage actually has a slight hydraulic slope toward the Great Gallery) and the water was made to flow out, at the floor of the Great Gallery, where it was conveyed toward the “Grotto”. Subsequently, a plug placed in the floor was removed to finish the emptying of the room. The water thus conveyed through the hole in the floor, highlighted in a book published in 1877 [14], allowed the liquid to enter the room which, in our 3D reconstruction, corresponds to the number 14, eventually reaching the “Unfinished” room and returning to the Nile. The “Grotto” and room 14 are, in our opinion, necessary to stop the fall of water by slowing down its speed, with a mechanism similar to a common water jet pump used in laboratories to create vacuum in equipment, which is called Venturi’s tube.
The evident traces of erosion due to water inside the pyramid rooms are in support of our interpretative hypothesis. The three boulders that today are wedged at the beginning of the oblique corridor leading to the Great Gallery would have been used as “plugs” to block the access of water to the exit of the pyramid or from the Queen’s chamber by making them flow in different positions as needed.
The existence of passage 18 seems to be related to a little open room, which has never been described by anyone but is well tracked by photographic evidence, that appears located at the top of the entrance of the Great Gallery and was probably employed as security exit.
Dont ignore the Upper Mortuary Temple
The entire system of the ramps highlighted by the SAR could be interpreted as a gigantic resonant structure, having the purpose of equalizing any differences in vibration between the north and south part of the pyramid, with the aim of making the square structure reach number 10, placed around the Zed, an equalized vibrational signal. Similarly, the complex structure number 9 identified immediately below the plane on which the pyramid rests has a shape similar to structures used to absorb the effects of mechanical vibrations that are transmitted through the ground [30].
So in that reading, I guess the structure we call the mortuary temple, joined by its roofed corrodor to the riverside part of the complex (which by Biondi and Malanger's reading would have been under 20 m of water) was used for undressing so the "indivudual" could enter the water-filled pyramid, swim up the dark Grand Gallery to the airlocks in either of the chambers, after just flipping aside the sets of granite plugs holding the water in.
