The Great Pyramid of Giza was built in Egypt over 4,500 years ago as a tomb for their pharaoh, Khufu, and it has since become one of the Seven Wonders of the Ancient World. For centuries, there have been speculations that this 230 meter structure contains hidden passageways and cavities. Recently, scientists discovered that it houses a secret void, one that is roughly 100-feet long.
Thanks to a new technique called tomography, archaeologists have been able to use cosmic rays that collide with Earth’s atmosphere to detect a sizable, previously undiscovered cavity inside the Great Pyramid of Giza. This breakthrough was brought by the ScanPyramids project, which is an international mission under the authority of Egypt’s Ministry of Antiquities. It is coordinated by the Faculty of Engineering at Cairo University and the HIP Institute, and the project’s purpose is to use non-invasive visualization techniques to see through the pyramids. The method has previously been used in Japan to see through active volcanoes as well as the reactors inside Fukushima. Essentially, “we tried to do for the pyramid what a doctor can do with X-rays,” says Dr. Tayoubi, the co-director of the ScanPyramids project. Using 3D scans with lasers and drones, the project has unveiled astounding results, all the while preserving the site without destroying the tombs and structures.
These new findings greatly contribute to the quest to understand the mystery of this pyramid, which has long been speculated on. The purpose of this seemingly empty room is unknown since it is still unclear as to what the nature and contents of this room may be, although some Egyptologists have already developed theories as to what the Egyptians used it for. Scientists have no plans to drill into it, but rest assured, they will be developing methods in the near future to discover the secrets that this void may hold.
