Think of the oldest piece of architecture you can imagine. Whether we’re being scientifically accurate or not, you might have thought of the Great Pyramid of Giza. This legendary Wonder of the World was built at some point between 2509 BC and 2483 BC. You’d imagine that by now scientists know everything there is to know about the great structure however a recent discovery has researchers everywhere raising their eyebrow. Scientists were able to use cosmic rays in order to reveal a large void within the Great Pyramid.

The massive void found within the Great Pyramid was found by a group of scientists that were tracking particles known as muons. It was revealed in the November 2nd, 2017 issue of Nature Magazine that the researchers had unveiled what they believe could be a new passage or a new chamber. The Great Pyramid of Giza, also known as Khufu’s pyramid, was studied by the Heritage Innovation Preservation as well as the team undertaking the ScanPyramids program. Mehdi Tayoubi, President and Leader of the aforementioned organizations, said: “The void is there.”

Despite the excitement conjured forth by such a discovery, some researchers were loathe to let it amount to much. The Egyptology as a whole decided to turn their noses ever so slightly up toward it. Zahi Hawass, a famous Egyptologist said, “It’s very clear what they found as a void doesn’t mean anything at all.” Hawass is a former minister in Egypt with a post at the antiquities and focus on excavations. Hawass may rightly be hesitant to endorse the new discovery due in large part to how Tayoubi’s team works.

Tayoubi works closely with fellow researchers but they avoid taking on any Egyptologists. Their goal is to look at the Pyramid of Giza with ‘fresh and maybe a naive eye’. In studying this way, Tayoubi’s team is able to avoid preconceived notions to get a more unbiased and potentially accurate outlook on whatever it is that they are studying.
