Scanning of the Great Pyramid of Egypt.

Thermal Scan of Egyptian Pyramids Reveals Mysterious Anomaly in the Great Pyramid

(Read the article on one page)

Scientists looking to uncover hidden chambers and other ancient secrets of the Egyptian pyramids for the first time using powerful scanning technology, have detected an ‘impressive’ anomaly within the Great Pyramid of Egypt, which could indicate something hidden behind the ancient walls.  The Egyptian Ministry has announced that they have several hypotheses, but will conduct more research before revealing them.

Researchers from Egypt, Canada, France and Japan started scanning the internal workings of four pyramids in Egypt, using advanced infrared technology and cosmic rays as part of an international project named Scan Pyramids , which aims to delve into the deepest recesses of the pyramids. So far, a number of anomalies in the heat signatures of the pyramids have been detected, but the Ministry of Antiquities announced one “particularly impressive one located on the Eastern side of the Khufu (Cheops) pyramid at ground level”.

"There is something like a small passage in the ground that you can see, leading up to the pyramids ground, reaching an area with a different temperature,” Antiquities Minister Mamdouh el-Damaty said in a press statement. “What will be behind it?"

Thermal mapping of the pyramids using infrared thermography is designed to identify any voids behind the pyramid walls, such as cavities, chambers, passages, or different types of construction materials, while cosmic-ray muons radiography detect unknown structures in the ancient monuments.

Discovery News reports that the Great Pyramid showed striking thermal differences. While temperature differences between two adjacent stones from limestone usually ranges from 0.1 to 0.5 degrees, the variation between blocks on the eastern side of the Great Pyramid is 6.0 degrees.

"This anomaly is really quite impressive and it’s just in front of us, at the ground level," said Mehdi Tayoubi, founder of the Paris-based  Heritage Innovation Preservation Institute  that is conducting the  Scan Pyramids  experiments.

Several thermal anomalies were observed on all monuments, but one, particularly impressive one, was detected on the eastern side of the Great Pyramid, also known as Khufu or Cheops, at the ground level.

At this stage, the research team is not revealing their hypotheses about the anomaly until further research is conducted.

Egyptologist Beth Ann Judas  said that the eastern side of the Great Pyramid, where the anomaly was found, was the focal point of the pyramid, with several major temples and tombs located on that side. "The Nile was to the east of the pyramid, and most everyone would have approached from the east," she said [via Huffington Post ]. "Pyramids also have a connection to the solar aspect, and the cult of the god Ra, in ancient Egyptian religion."

Tayoubi said that the next stage of investigations will involve building models and thermal simulations to test out different theories. The Scan Pyramids project is scheduled to last over a year, and will involve long term infrared survey of four pyramids – Khufu and Khafre at Giza, and the Bent pyramid and Red pyramid at Dahshur.

tidal forces? From a river?  how much googling did your “Research” involve?

I'm assuming you meant mica. Formica is some wood laminate.

If it was covered in Quartz then how did it erode? It wouldn't have been stolen as Quartz is quite cheap. Did you find Quartz blocks or fine Quartz particles around the base?

I agree it had some covering because the surface is too rough. If I was its sponsor I'd not leave it unfinished and rough like it is now.

Any student of history knows that the Pyramid was finished with a surface of white limestone, that has since been pilfered. And the sides are known to be slightly concave, so that the Pyramid is actually eight-sided.

Fide et Literis

I believe the pyramids at Giza were built long before the Egyptians came to that land. Historians try to explain them as burial chambers even though no evidence supports such claims. They also try to claim the "bent" and "step" pyramids were first attempts at constructing that culminated in the three large edifices on the plateau. This is a blatant lie. No one seems to explain how the structures suddenly appeared in the Forth Dynasty (26133-2498 BCE ) but the builders had no idea how to build them in the Third Dynasty, then completely lost the art again in the Fifth! Actually, the structures were found buried beneath the sands during the Fourth Dynasty! Egyptian Kings then claimed them as burial chambers and attempted to build more but failed, resulting the step and bent ones. These were the last efforts, not the first

Myths & Legends

Open Book Photo
A legend is a tale regarded as historical even though it has not been proven, and the term “myth” can refer to common yet false ideas. Many myths and legends describe our history, but they are often treated skeptically. This is because many of them, while explaining a phenomenon, involve divine or supernatural beings.


The ancient and mysterious Sphinx, Giza, Egypt.
In 1995, NBC televised a prime-time documentary hosted by actor Charlton Heston and directed by Bill Cote, called Mystery of the Sphinx. The program centered on the research and writings of John Anthony West, a (non-academic) Egyptologist, who, along with Dr. Robert Schoch, a professor of Geology at Boston University, made an astounding discovery on the Great Sphinx of Giza in Egypt.

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
