Great Void discovered in Pyramid of Giza

Great Void

Cosmic rays, harnessed from space, have been used to create a new scan of the Great Pyramid of Giza.

A great void has been discovered in the depths of the pyramid, one which engineers and scientists never knew existed before now.

Findings were published in science journal Nature this week, and the abstract to the piece reads like the set up for a particularly outlandish movie:

The Great Pyramid or Khufu’s Pyramid was built on the Giza Plateau (Egypt) during the IVth dynasty by the pharaoh Khufu (Cheops), who reigned from 2509 to 2483 BC1. Despite being one of the oldest and largest monuments on Earth, there is no consensus about how it was built2,3. To better understand its internal structure, we imaged the pyramid using muons, which are by-products of cosmic rays that are only partially absorbed by stone4–6. The resulting cosmic-ray muon radiography allows us to visualize the known and potentially unknown voids in the pyramid in a non-invasive way.

Here we report the discovery of a large void (with a cross section similar to the Grand Gallery and a length of 30 m minimum) above the Grand Gallery, which constitutes the first major inner structure found in the Great Pyramid since the 19th century 1.

This void, named ScanPyramids Big Void, was first observed with nuclear emulsion films7–9 installed in the Queen’s chamber (Nagoya University), then confirmed with scintillator hodoscopes10,11 set up in the same chamber (KEK) and re-confirmed with gas detectors12 outside of the pyramid (CEA).

This large void has therefore been detected with a high confidence by three different muon detection technologies and three independent analyses. These results constitute a breakthrough for the understanding of Khufu’s Pyramid and its internal structure. While there is currently no information about the role of this void, these findings show how modern particle physics can shed new light on the world’s archaeological heritage.”

Harnessing then rays allowed the participants to safely explore the inner workings of the Great Pyramid, as shown below:

Non-invasive investigation into the void will continue over the coming months.
