The existence of a hidden passage in the northern face of the Great Pyramid of Giza has long been a topic of discussion. However, a recent study published in 'Scientific Reports' has introduced new insights using electrical resistance imaging technology for the first time in this context. This innovative approach helps researchers identify areas within the pyramid where electricity encounters resistance, suggesting the presence of voids or corridors.

Led by Dr. Hani Hilal, an engineering professor at Cairo University and former Minister of Higher Education, the 'Scan Pyramids' project engaged an international research team to conduct these experiments. The researchers positioned electrodes on the surface of the Great Pyramid and then passed a weak, safe current through them. By measuring how the electrical current traveled through the structure, they were able to generate a three-dimensional image that provides insight into the hidden architecture of this ancient monument.

This breakthrough not only adds to our understanding of the pyramid's structure but also raises questions about the construction techniques used in ancient Egypt. It opens up possibilities for further exploration and could lead to significant findings regarding the historical significance of the Great Pyramid and its builders.
