The ScanPyramids [1] mission is an Egyptian-International project designed and led by Cairo University and the French HIP Institute (Heritage Innovation Preservation). [2] This project aims at scanning Old Kingdom Egyptian Pyramids (Khufu, Khafre, the Bent and the Red) to detect the presence of unknown internal voids and structures. [3]
The project, launched in October 2015, [4] combines several non-invasive and non-destructive techniques which may help to get a better understanding of their structure and their construction processes and techniques.[ clarification needed ] The team was using Infrared thermography, muon tomography, 3D simulation and reconstruction techniques. [5] [6]
ScanPyramids is an interdisciplinary project mixing art, science and technology. [7] On November 2, 2017, the ScanPyramids team announced, through a publication in Nature, [8] its third discovery in the Great Pyramid, a "plane-sized" [9] previously unknown void named the "ScanPyramids Big Void". [10]
On October 15, 2016, ScanPyramids confirmed their first unknown void discoveries thanks to muon tomography in the Great Pyramid. [11] [12] A previously unknown cavity [13] was confirmed on the North-Eastern Edge, [14] roughly at 110 metres (360 ft) high with similar void volume characteristics as a known "cave" located at 83 metres (272 ft) on the same edge. [15]
A second void was discovered behind the chevrons area of Khufu's North Face above the Descending Corridor (referred to as "SP-NFC" in papers). This area was investigated after thermal anomalies observation that led the team to position muon emulsion plates in the Descending Corridor. [5] [16] This void was further investigated during 2017 to provide more information about its shape, size, and exact position. [5] [17]
In 2017 more muon-sensitive emulsion plates were positioned in the descending corridor and in Al-Mamun's tunnel [ broken anchor ]. The void behind the chevrons could be confirmed through different points of view and its characteristics refined. Named "ScanPyramids North-Face Corridor" (SP-NFC), this void is located between 17 and 23 metres (56 and 75 ft) from the Great Pyramid's ground level, between 0.7 and 2 metres (2 ft 4 in and 6 ft 7 in) from the North Face. It could be horizontal or sloping upwards and it has a corridor-like shape. [19]

On November 2, 2017, the ScanPyramids team published its third discovery in Nature , which was named "ScanPyramids Big Void", or "SP-BV" for short. It describes a newly discovered huge void in a circumscribed area above the Grand Gallery. It is estimated to have a length of at least 30 metres (98 ft) and a similar cross-section as the Grand Gallery. The ScanPyramids Big Void has been observed by three teams of physicists from different points of view (2 points of view in the Queen's Chamber and from outside in front of the North Face). [8]
Three scientific institutions specializing in particle physics have worked independently and each one used a different and complementary muography technique:
Like the work done on the "ScanPyramids North Face Corridor", more muography observations, from new viewpoints, need to be conducted in order to better determine the Big Void's shape, so that functional inferences can be drawn. [22] [ unreliable source? ] [23] As long the exact layout and function of the void is still unknown, the scientists have been cautious about using architectural nomenclature. [24]
In March 2023, the team published [25] its finding of the North Facing Corridor (NFC) behind the original entrance; the void is called "SP-NFC" (ScanPyramids - North Face Corridor) in the paper. [26]
On November 2, 2017, the Egyptologist Zahi Hawass told the New York Times: "They found nothing...This paper offers nothing to Egyptology. Zero." [27]
On November 3, 2017, Egypt's Ministry of Tourism and Antiquities said in a statement, "The existence of several void spaces inside the pyramid is not a new thing. Egyptologists and scholars knew about it several years ago," adding, "the ministry sees that the ScanPyramid team should not have rushed [ sic ] to publish their findings in media at that stage of their research because it requires more research and it is too early to say that there was a new discovery." [28]
On November 4, Khaled al-Anany, Egyptian Minister of Antiquities said, during a press conference, that the void space found inside the Great Pyramid of Khufu by the ScanPyramids project is a new revelation that brought the world's attention to Egypt. He added "What was discovered is new and larger than the known cavities, and we'll continue in our scientific steps". [29]
Other Egyptologists have welcomed the discovery. Yukinori Kawae told National Geographic "This is definitely the discovery of the century...There have been many hypotheses about the pyramid, but no one even imagined that such a big void is located above the Grand Gallery." [30] [31]
Peter der Manuelian, from Harvard University, said that "This is an exciting new discovery, and potentially a major contribution to our knowledge about the Great Pyramid." [32] [23]
Lee Thompson, an expert in particle physics at the University of Sheffield (UK) told Science: "The scientists have "seen" the void using three different muon detectors in three independent experiments, which makes their finding very robust." [33] Christopher Morris, physicist at Los Alamos National Laboratory called the findings "pretty amazing". [34] Jerry Anderson who worked on Khafre's Pyramid and was a member of the team of Luis Walter Alvarez, the first scientist to use muography inside a pyramid in 1965, [35] said to Los Angeles Times, with a laugh: "I am very excited and very pleased,...I wish we had worked in the Great Pyramid, now that I look back on it". [36]
This discovery has been featured in many international media as one of the top discoveries of the year 2017 (NBC News, [37] Euronews, [38] Physics World, [39] Science News, [40] Global News, [41] Gizmodo, [42] Business Insider, [43] Altmetric, [44] Egypt Today, [45] NBC, [46] MSN News, [47] Le Monde, [48] CTV, [49] The Franklin Institute, [50] Radio Canada, [51] Sciences et Avenir, [52] RTÉ, [53] PBS, [54] Yahoo, [55] La Vanguardia, [56] France Info [57] ).
The Great Pyramid of Giza is the largest Egyptian pyramid. It served as the tomb of pharaoh Khufu, who ruled during the Fourth Dynasty of the Old Kingdom. Built c. 2600 BC, over a period of about 27 years, the pyramid is the oldest of the Seven Wonders of the Ancient World, and the only wonder that has remained largely intact. It is the most famous monument of the Giza pyramid complex, which is part of the UNESCO World Heritage Site "Memphis and its Necropolis". It is situated at the northeastern end of the line of the three main pyramids at Giza.
A muon is an elementary particle similar to the electron, with an electric charge of −1 e and spin-1/2, but with a much greater mass. It is classified as a lepton. As with other leptons, the muon is not thought to be composed of any simpler particles.
Khufu or Cheops was an ancient Egyptian monarch who was the second pharaoh of the Fourth Dynasty, in the first half of the Old Kingdom period. Khufu succeeded his father Sneferu as king. He is generally accepted as having commissioned the Great Pyramid of Giza, one of the Seven Wonders of the Ancient World, but many other aspects of his reign are poorly documented.

The Egyptian pyramids are ancient masonry structures located in Egypt. Sources cite at least 118 identified "Egyptian" pyramids. Approximately 80 pyramids were built within the Kingdom of Kush, now located in the modern country of Sudan. Of those located in modern Egypt, most were built as tombs for the country's pharaohs and their consorts during the Old and Middle Kingdom periods.
The Giza pyramid complex in Egypt is home to the Great Pyramid, the Pyramid of Khafre, and the Pyramid of Menkaure, along with their associated pyramid complexes and the Great Sphinx. All were built during the Fourth Dynasty of the Old Kingdom of ancient Egypt, between c. 2600 – c. 2500 BC. The site also includes several temples, cemeteries, and the remains of a workers' village.
The Giza Plateau is a limestone plateau in Giza, Egypt, the site of the Fourth Dynasty Giza pyramid complex, which includes the pyramids of Khufu, Khafre and Menkaure, the Great Sphinx, several cemeteries, a workers' village and an industrial complex. It forms the northernmost part of the 16,000 ha Pyramid Fields in the Western Desert edge of the Nile Valley that are part of the UNESCO World Heritage Site, Memphis and its Necropolis.

The Khufu ship is an intact full-size solar barque from ancient Egypt. It was sealed into a pit alongside the Great Pyramid of pharaoh Khufu around 2500 BC, during the Fourth Dynasty of the ancient Egyptian Old Kingdom. Like other buried Ancient Egyptian ships, it was part of the extensive grave goods intended for use in the afterlife. The Khufu ship is one of the oldest, largest, best preserved vessels from antiquity. It is 43.4 metres (142 ft) long, 5.9 metres (19 ft) wide, and 1.78 meters deep, and is the world's oldest intact ship. It has been described as "a masterpiece of woodcraft" that could sail today if put into a lake or a river.
Meritites I was an ancient Egyptian queen of the 4th Dynasty. Her name means "Beloved of her Father". Several of her titles are known from a stela found at Giza. She was buried in the middle Queen’s Pyramid in Giza.
G1-c is one of the subsidiary pyramids of the Giza East Field of the Giza Necropolis immediately to the eastern side of the Great Pyramid of Giza, built during the Fourth Dynasty of Egypt. It is the southern of the three pyramids of the queens and is the one of Queen Henutsen. It is 46.25 metres wide and had a height of 29.60 metres. A niche, four inches deep was dug in the south wall of the burial chamber. Pyramid G1-c was originally not a part of Khufu's pyramid complex, as its southern side is aligned not with the side of the Great Pyramid, but with Khufukhaf I's mastaba tomb nearby. Pyramid G1-c was at some point thought to possibly be a satellite pyramid, because it did not come with a boat pit like pyramids G1-a and G1-b. It was later determined to be an unfinished pyramid which was constructed in a hurry. Henutsen is thought to have been buried in the tomb. Dr. Rainer Stadelmann believes Khufukhaf is the same person as Khafra and the pyramid was built by him for his mother, but this identification is doubtful.
Pyramid G1-d is a satellite pyramid within the Khufu pyramid complex on the Giza plateau.
Several ancient Egyptian solar ships and boat pits were found in many ancient Egyptian sites. The most famous is the Khufu ship, which is now preserved in the Grand Egyptian Museum. The full-sized ships or boats were buried near ancient Egyptian pyramids or temples at many sites. The history and function of the ships are not precisely known. They are most commonly created as a "solar barge", a ritual vessel to carry the resurrected king with the sun god Ra across the heavens. This is a common theme in the Pyramid Texts, and these buried boats might be a real-life equivalent of solar barges. Similarly, another explanation behind these boats is that they were built for past kings to carry them to the afterlife. Because of these ships' association with the sun, they are often found in an east-west orientation in order to follow the path of the sun.
The Giza Solar boat museum was dedicated to display the reconstructed Khufu ship, a solar barque of pharaoh Khufu. It was constructed between 1961 and 1982, just a few meters from where the Khufu ship was found, on the southern side of the Great Pyramid, on the Giza Plateau in Egypt

Muon tomography or muography is a technique that uses cosmic ray muons to generate two or three-dimensional images of volumes using information contained in the Coulomb scattering of the muons. Since muons are much more deeply penetrating than X-rays, muon tomography can be used to image through much thicker material than x-ray based tomography such as CT scanning. The muon flux at the Earth's surface is such that a single muon passes through an area the size of a human hand per second.
The Diary of Merer is the name for papyrus logbooks written over 4,500 years ago by Merer, a middle-ranking official with the title inspector. They are the oldest known papyri with text, dating to the 27th year of the reign of Pharaoh Khufu during the Fourth Dynasty of Egypt. The text, written with (hieratic) hieroglyphs, mostly consists of lists of the daily activities of Merer and his crew. The best preserved sections document the transportation of white limestone blocks from the Tura quarries to Giza by boat.

We're avoiding the word 'chamber', we know that it's a big void, but we're not calling it a chamber
They found nothing," said Dr. Hawass, noting that such construction gaps had been known of for at least two decades. "This paper offers nothing to Egyptology. Zero.
"What was discovered is new and larger than the known cavities, and we'll continue in our scientific steps," Anany said
There have been many hypotheses about the pyramid, but no one even imagined that such a big void is located above the Grand Gallery.
Peter Der Manuelian, professor of Egyptology and director of the Harvard Semitic Museum, said the discovery was "potentially a major contribution to our knowledge about the Great Pyramid."
