Never before seen tunnel discovered in the Pyramid of Giza

Researchers revealed a never before seen corridor in the Great Pyramid of Giza, the last of the Ancient Seven Wonders of the World still standing.

The study published in the Nature Communications journal used a technology called cosmic-ray muon radiography to see into the pyramid in a nondestructive way, revealing a previously undiscovered tunnel along the north face, almost 5 meters behind what is called the “chevron zone” of the pyramid.

When the researchers took a second look using better technology, they found that the corridor was over 9 meters long and 2 meters wide, with a chevron shape on the ceiling.

This could be the first time any human had seen the inside of this corridor in 4,500 years.
