Scientists Map an Unexplored Corridor of Egypt's Great Pyramid Using Cosmic Rays
Thanks to cosmic rays, secrets of the last remaining Wonder of the Ancient World are being revealed.

The Great Pyramid of Giza, the largest of Egypt's famous landmarks, has stood tall for around 4,500 years. But the 2 million blocks that make up the tomb and fortress have not been impenetrable. Looters robbed the structure of its ancient treasures thousands of years ago and scientists have probed its interiors either by studying its corridors or with more advanced measuring techniques like thermal scanners.

The structure still holds many secrets, but since 2015 an international team of scientists, the ScanPyramids team, has been using subatomic particles to probe the unknowns of the monument. In 2017, they revealed a huge void -- creatively dubbed the Big Void -- situated above the pyramid's gallery, though the purpose of this void remains unknown.

On Thursday, in a study published in the journal Nature Communications, the team characterizes the structure of this corridor by taking advantage of the cosmic rays that constantly smash into the Earth.
